I HAVE again been called on to aid in laying before the public an account of the Life and Work of an eminent member of my own profession; the reason being, as in former cases, an impression that occupations and pursuits so largely technical would be most appropriately described by some one familiar with them. I may further plead the justification of a close personal intimacy with Sir William Siemens during the greater part of his residence in England; and the fact of his having, a few years before his death, specially asked me to undertake some important literary work connected with his professional and scientific labours. This book may probably have three distinct classes of readers, each differently interested in its contents. The large circle of Sir William's private friends vi PREFACE. may expect to find in it the history of all the varied events of his chequered life; another large group of experts may look more specially for full records of his engineering and scientific labours; while the general public may only desire to learn what manner of man he was, and how he came to gain such honour and popularity. It has not been easy to provide simultaneously for all these requirements: to chronicle personal occurrences without appearing trivial, or to explain technical details without being dull. I must crave indulgence for any shortcomings, and shall be satis- fied if I may have succeeded in making the book generally readable. This In the last chapter there will be found a some- what full mention of published obituaries and press notices, called forth by Sir William's decease. might perhaps seem to savour of ostentation; but it has been the opinion of his friends that such spon- taneous and widely-spread testimony to his character and merits ought not to be ignored. It would hardly be necessary for English readers, but as a demand has been made for a German translation of the work, the notices in question will furnish to his PREFACE. vii compatriots a more unequivocal proof than could be given by any other means, of the estimation in which he was held in the country of his adoption. In the many cases where it has been necessary to mention Sir William's papers, communications, lectures, addresses, and so on, the quotations from them have been confined to such portions as were necessary to complete the narrative or to make it intelligible. The most important of these docu- ments will be reprinted in the volumes accompany- ing this work, and they can be easily referred to for any further information that may be desired. The history of Sir William's youth has been drawn from reminiscences furnished by his brother Werner; that of his early manhood has been obtained chiefly from an enormous mass of German correspondence, the deciphering of which I could hardly have undertaken had I not been kindly given most efficient aid by the executors. To them (particularly to Mr. Alexander Siemens), as well as to Lady Siemens and to other members of Sir William's and her family, I have to express my best acknowledgments for help in many ways throughout the work. viii PREFACE. My thanks are also similarly due to Sir William's secretary, Mr. E. F. Bamber; Mr. James Forrest, secretary of the Institution of Civil Engineers; Mr. Trueman Wood, secretary of the Society of Arts; as well as to Sir Frederick Bramwell, Sir William Thomson, Mr. W. H. Barlow, Mr. E. A. Cowper, and many other friends. ATHENÆUM CLUB, London, S.W. September, 1888. W. P. CONTENTS. CHAPTER I. INTRODUCTION.

Grounds on which the Biographies of Engineers may claim Attention— The Interest of such Biographies lies not only in the way a man has done his Work, but largely in the nature of the Work itself— What Engineering means: Derivation of the Word-Authoritative Description by the Institution of Civil Engineers—Magnitude and Importance of the Objects embraced in the Profession-Necessity of Division of Labour-Special Branches taken up by different Practitioners-General Nature of the Work to which Sir William Siemens devoted his Life. IN adding another Biography of an eminent Engineer to the many already existing, it may not be out of place to state briefly the grounds on which it is hoped that such a book may have a claim to attention. The interest of the Life of an Engineer will be found to lie, not only in the personal character and doings of the individual, but also, to a large extent, in the nature of his occupations. This is an important peculiarity in engineer- ing biography which must always be borne in mind in estimating its value. When an active worker in one of the more familiar walks of life has merited a public record, it may be usually taken for granted that the subjects of his labours will already be 49 B 2 [CHAP. I. INTRODUCTION. tolerably well known, and that the interest will depend on his personal manner of dealing with them. But this is not so with the Engineer. His profession is of such recent origin, of such wide extent, and of such great variety, that the ideas ordinarily prevailing in the public mind respecting the works and operations comprised in it, are necessarily very imperfect and vague. Hence it follows that when a man has made his mark in this profession, the nature of his work has to be explained to the reader, as well as the manner in which he has done it. And it may reasonably be expected that this additional information will enhance the interest of the book, as well as render it more intelligible. It may therefore be desir- able here to say a few words on the profession of Engineer- ing generally, and to explain the peculiar phases of it with which Sir William Siemens had chiefly to do. The term Engineer is popularly supposed to denote a person who has to do with engines,-but this is a fallacy. The true derivation of the word is of a much higher and more honourable character. Littré has shown that its root is to be found in the Sanscrit jan, to be born, from which came the Greek form yev, and the Latin gen. The latter entered into the French language in the form of a verb, s'ingénier, which all the best authorities agree to be the true origin of the word "Engineer." The meaning of this French verb is stated to be,* "chercher dans son génie, dans son esprit, quelque moyen pour réussir." Thus we arrive at the interesting and certainly little known fact, that an engineer is, according to the strict deri- The author may * Littré, Dictionnaire de la Langue Française. venture to refer, for further historical details, to his "Life of Sir Wil- liam Fairbairn, Bart." Large Edition. London, 1877. Chapters I. and II. CHAP. I.] THE ENGINEERING PROFESSION. 3 vation of the term, anyone who seeks in his mind, who sets his mental powers in action, in order to discover or devise some means of succeeding in a difficult task he may have. to perform. It would be impossible to give a nobler or more appropriate description than this, of the manner in which our greatest engineering works have been produced, or the nature of the qualifications by which the greatest men in the profession have acquired their renown. A year or two ago the Institution of Civil Engineers, finding that some misunderstanding existed, even among engineers themselves, as to the precise nature and extent of the occupations legitimately constituting their pro- fession, took some pains, for the sake of their own disci- pline, to define them; and this formal definition, given by the body exercising the chief guardianship of professional interests, may therefore be received as fully authoritative. The Council of the Institution quote a well-known early definition given in their Royal Charter of Incorporation passed in 1828, namely, that the profession of a Civil Engineer is- "The art of directing the great sources of Power in Nature for the use and convenience of Man." This is a very good description, as far as it goes, and we shall see hereafter that it is peculiarly appropriate to the labours of the subject of this Biography. But the Council proceed to explain that the endea- vour to utilise such powers has necessarily led to great varieties of operations of a scientific character, constantly enlarging their boundaries; so that, in the words of one of the early masters of the profession, "The scope and utility of Engineering will be increased with every discovery in philosophy, and its resources with every invention in mechanical or chemical science." They then state that, according to modern usage, the practitioners in the art may B 2 4 [CHAP. I. INTRODUCTION. have to do with many classes of works, giving the following as examples :- 1. Works for facilitating and improving internal commu- nications-as roads, railways, tramways, navigation by canals and rivers, bridges, and telegraphs of various kinds. 2. Works connected with the sea-coast, and for facilitat- ing communication between the sea and the land, such as harbours, docks, piers, breakwaters, sea-walls, and light- houses. 3. Works for facilitating communication across the seas; including naval architecture, iron shipbuilding, and the construction and laying of submarine telegraph cables. 4. Works for the reclamation, irrigation, or drainage of land; and for the prevention or the regulation of floods, including the improvement of rivers as arterial drains. 5. Works for cities and towns, such as sewerage, water supply, lighting, and street improvements. 6. Large and massive buildings generally, in their scientific and mechanical arrangements. 7. The operations of mining and of metallurgy, so far as they involve the application of mechanical science. 8. The design and construction of the mechanical prime- movers, such as steam-engines, water-wheels and other hydraulic motors, windmills, electric and other engines. 9. The design, construction, and adaptation to practical use of machinery and mechanical appliances of all kinds. 10. The design and manufacture generally of all large and important metallic structures, including artillery, and other large munitions of war. As the Council justly remark, this is indeed a compre- hensive catalogue, and if we consider the quantity of work that has been done under these various heads during the last century, and contemplate the effect that this work has had on trade, on commerce, on finance, on government, CHAP. I.] SIR WILLIAM SIEMENȘ'S WORK. 5 and indeed on every possible aspect of human interests, we cannot hesitate to admit that the profession of Engineering has become truly a great power. Now it will be easily understood, considering the vast extent and variety of the works comprised in the above list, that it has been found convenient to apply largely in the profession the plan of division of labour. The general scientific principles underlying the whole are pretty much the same; but the practical nature of the work to be done is so varied that certain practitioners have found it to their own interest, as well as to that of their clients, to con- fine their practice to certain special kinds of work. Thus some engineers devote their attention chiefly to railways and their adjuncts; some to hydraulic constructions; some to naval architecture; some to water and gas supply; some to mining; some to metallurgy; some to electric works; some to mechanical constructions; and so on. In describing Sir William Siemens's connexion with the profession, it would be easy to place him as a specialist in certain of the classes named in the Institution list; but it will be more appropriate to refer back in his case to the earlier general characteristic, "the art of directing the great Powers in Nature for the use and convenience of Man." This was essentially the work of his life; he took two great powers in nature, or, as he would have preferred to say, two forms of natural energy, HEAT and ELECTRICITY, and his life was chiefly and successfully devoted to direct- ing them for the use and benefit of mankind. In regard to Heat, his labours referred to new modes of its application, which not only effected great economy, but gave vast increase of power-advantages which may be said to have almost revolutionized many manufacturing industries. And as an outcome of this he was enabled, by 6 [CHAP. I. INTRODUCTION. new metallurgical processes, to extend enormously the use and the value of one of the most important of constructive materials known to Engineers. In regard to Electricity, he contributed materially to the inventions which gave it its wonderful modern develop- ment, and to the establishment of manufactories on the largest and most complete scale, which brought the new power into extensive practical application for the benefit of the world. But all this work, fraught with such great results, was not simple and easy to do; it involved long years of con- stant mental study and practical effort, interspersed with many trying difficulties, discouraging failures, and heavy losses; and it was only by perseverance and determination that success was at last attained. To chronicle all this, in such a manner as to do justice to Sir William Siemens's character, will require, as has already been stated, a good deal of explanation, which, though of a somewhat technical character, may, it is hoped, contribute to the interest of the personal history. And it may be added, that such was the activity of Sir William's mind, and such the versatility of his powers, that in addition to the two main objects of his work, he, particularly in the latter portion of his life, gave attention to many other matters which had little connexion with them, but which from their philosophical nature and useful bearing are eminently worthy of being recorded. His life was one of continual thought, leading to con- tinual activity, and resulting in continual usefulness. His labours were fully appreciated, and his name cannot fail to retain an honourable place in the records of the Engineer- ing Profession. FREDERICK WE NERVSIEMENS SIEMENS CARL SIEMENS CHAPTER II. PARENTAGE AND FAMILY. Father, his Position and Character-Mother-Number of Children: Werner, Hans, Ferdinand, William, Friedrich, Carl, Walter, Otto -Daughters-Business Relations between the Brothers-Family Customs-The "Siemens Stift." THE name of SIEMENS has been made famous by others bearing it, as well as by the subject of this Memoir; indeed it would be difficult to find a modern instance of a family comprising so many individuals whose intellcctual powers and technical genius have come prominently before the world. And having regard to the fact that close relations existed between William Siemens and several of his brothers during his whole career, it is desirable to give a somewhat full notice of the family generally. The father, Christian Ferdinand Siemens, was born in 1789 at Wasserleben, on the northern edge of the Harz Mountains. He was the youngest son in a large family, and his ancestors had, for three centuries before, been country people, engaged in the cultivation of the land. Ferdinand, as he was called, married early, and settled in the same line of life, at a small place called Lenthe, a few miles from Hanover, where he held the position of Domänen-Pächter, the title given to those who farm and cultivate Government lands. S [CHAP. II. PARENTAGE AND FAMILY. He had received, in common with all his father's children, a liberal education, and one of his brothers became Professor of Mathematics at the University of Halle. In a document written by William in 1873,* he says that his father had a good healthy organization; was energetic and of a restless disposition; was passionate, but tender-hearted; that his impatience was easily and forcibly excited; that he actively pursued historical studies, and had an excellent memory for historical events, including dates and names in ancient and modern history; had a studious and receptive mind; was independent in judg- ment, with a high moral standard, but was decidedly eccentric, in showing plainly his intense dislike to humbug or mere formalism. He was a fair classical scholar, but he had no pretensions to scientific knowledge, or to any acquaintance with the subjects on which his sons made themselves so famous. The lady he married, by name Eleonore Deichmann, born 1793, also came from a North German country family residing near Hanover. Her son said of her that she was of delicate figure, healthy when young, but subject to nervous disorders in after-life. She had a good general education; was high-minded and self-sacrificing; extremely sensitive; and devoted to her children, but without in- dulging them. She had a naturally religious mind, above formalities, and with somewhat excessive sense of duty. She was very gentle and amiable in character. It is recorded that she was refined and cultured in her tastes, and fond of poetry, sometimes writing it herself. The couple had a large family, eleven sons and three Kindly lent to the Author by Mr. Francis Galton. CHAP. II.] 9 FATHER AND MOTHER. daughters, of whom three sons and one daughter died in infancy. The occupation followed by Ferdinand Siemens was fairly profitable, and he may be said to have been in com- fortable circumstances; but his means were not so large as to enable him to do more for all these children than to give them the plain but substantial education which is within the reach of the middle-classes in Germany. In the year 1823, a few months after the birth of William, he gave up his position at Lenthe and removed, with his family, to a larger estate which he had leased at Menzendorf, near Lübeck, in the Grand Duchy of Mecklenburg. Here he lived for the remainder of his days. His faithful partner in life, worn out by the trials attendant on her large family, died in July, 1839, and he, unable to bear up under the heavy affliction of her loss, followed her six months later. A few years after his death, the estate at Menzendorf was given up, and the children were dispersed among relations and friends. The eldest son, Ernst Werner von Siemens, "the Berlin Siemens," as he is generally called, is deservedly looked up to as the founder of the fortunes and the reputation of the family, and he deserves special mention here from the fact of his having always assumed towards his brother William the position of his kindest patron, most trusted adviser, and most affectionate friend. * Werner was born at Lenthe, in 1816, and received his education at the Gymnasium of Lübeck. He showed an * Some of the information in this chapter is taken, by permission of the publishers, from an article in Cassell's Family Magazine, “A Family of Inventors,” which was translated, by Lady Siemens, from a German periodical. ΙΟ [CHAP. II. PARENTAGE AND FAMILY. inclination for the military profession, and in 1834 went to Magdeburg to enter the Prussian Artillery service as a volunteer. His eminent talents opened to him, in the following year, the doors of the Military School in Berlin, where he studied for three years, devoting his chief attention to mathematics, mechanics, and chemistry. In 1838, having received his commission as lieutenant, he returned to Magdeburg for active service, keeping up however, continually, his scientific reading. A year or two later he was transferred to the Technical Division of the Artillery, at Spandau, and soon afterwards to Berlin. In the meantime he had endeavoured to turn his scientific knowledge to some account. He had interested himself in the application of electricity to the deposition of metals; he had taken out a patent for the process, and later on he established in Berlin a small factory (the first in Germany) for carrying it into practice. In 1844 he was appointed to the important scientific post of Superintendent of the Artillery workshops; and this led him to throw himself with more ardour than ever into scientific pursuits, especially in regard to electricity, which was then beginning to acquire greater importance, from the introduction of the electric telegraph. Werner saw what a fertile field this invention would offer for his labours, and as early as 1846, he brought out important inventions relating to it, which gained him so much notice, that in the following year he was named a member of the commission for introducing the new telegraphs into Prussia. At this time, too, he founded, in conjunction with a friend, Mr. Halske, a manufactory of electrical apparatus in Berlin. But he was still a military officer, and in 1848 his duties called him to Kiel, where Danish men-of-war threatened the defenceless coast. Here, in conjunction with his CHAP. II.] II : WERNER VON SIEMENS. brother-in-law, Professor Himly, of Kiel, he laid the first submarine mines with electric ignition, the precursors of the modern torpedo. In the summer of the year 1848, he, acting as commandant of Friedrichsort, built the after- wards celebrated fortifications for the protection of the harbour of Eckernförde. In the autumn of the same year, he was recalled to Berlin in order to erect for the Government the first line of telegraphs in Germany, being that from Berlin to Frank- fort-on-the-Maine, where at that time the first German Parliament was assembled. This line was for its greater portion laid under ground in accordance with his proposi- tions, the conducting wires being for the first time insulated by gutta-percha; an invention which afterwards proved of much importance in the manufacture of submarine cables. After this he left the army, and devoted his whole atten- tion to his electrical pursuits. The factory, established shortly before, soon acquired large dimensions, and became one of the chief centres for the applications of electricity. and magnetism in the industrial arts. The firm of Siemens and Halske grew famous for the number of inventions and improvements introduced by them, as well as for the high quality and careful manufacture of the work they supplied. At a later period this firm, with the co-operation of some of Mr. Siemens's brothers, established large branch works at St. Petersburg, Vienna, Paris, and elsewhere. Werner von Siemens has also done much purely scientific work, and many honours have been conferred on him. In 1860 the University of Berlin conferred on him a Doctorate (honoris causâ); in 1874 he was elected a member of the Royal Academy of Sciences of Berlin; and he has lately been created a Knight of the Prussian Order “pour le Mérite," the highest scientific honour in that country, on account of his distinguished services to science and the I 2 [CHAP. II. PARENTAGE AND FAMILY. arts. He is an honorary member of many scientific socie- ties in many countries, and in Germany, not only is his name held in high esteem by men of science, but he is deservedly popular among the German people, who daily in their workshops are brought into contact with the results of his inventive genius. He was raised to the rank of nobility by the Emperor Frederick III., in 1888. The second son, Hans, born 1818, originally followed his father's pursuits; but afterwards devoted himself to indus- trial occupations. He owned a spirit distillery, and con- trived some new apparatus used therein. After the inven- tion and perfecting of the regenerative furnace by his brothers Frederick and William, he established large glass- works at Dresden, for the purpose of applying the furnace to that branch of manufacture, an improvement which was very successful. He died in 1867. The third son, Ferdinand, took entirely to his father's career, and, after managing one or two different properties, he purchased and settled on a large estate near Königs- berg, in East Prussia, where he still resides. The fourth son, William, is the subject of this biography. The fifth son, Friedrich, “ the Dresden Siemens,” as he is called, was born at Menzendorf in 1826. Like his brothers, he was intended to pass through the course of the gymnasium of Lübeck, but, having reached the third class, the desire of liberty urged him to abandon his place on the school bench, and to go forth into the world. He went on board a merchant ship when scarcely sixteen years of age, and there this youth, whose mental capacities afterwards proved so great, worked before the mast as a common sailor. After two years of this seafaring CHAP. II.] 13 FREDERICK SIEMENS. life his brother Werner tried to get him into the Prussian marine service, but while waiting in Berlin for this appoint- ment, Frederick was allowed to assist in the manifold ex- periments of his brothers. This chained him with a power very different from that which bound him to the ship, and out of the young sailor there was soon formed a clever, industrious, technical workman, who also afterwards became an originator on his own account. In 1848 Frederick was sent with telegraphic apparatus to England, where he joined his brother William, and studied under his direction. They remained together many years, and the important part taken by Frederick in regard to Heat Applications and the Regenerative Furnace will be found chronicled in Chapters V. and VI. When Hans Siemens died in 1867, Frederick undertook the management of the large glassworks in Dresden, and concentrated his talents on perfecting the manufacture there, so placing these works among the most important industrial establishments in Germany. He has also founded three other similar factories in Bohemia and Saxony, which give employment at present to two thousand workmen. In addition to the regenerative system of heating, he carried out an important invention in the "continuously working glass furnace," in which the rough materials being inserted at one end, the glass flows out thoroughly melted and ready for working at the other end. A further discovery of his is a new mode of cooling, which produces a material called "toughened glass," of extraordinary resistance. He has also paid much attention to the use of gas for heating and lighting, and by applying the regenerative principle he has constructed gas-burners giving a much more powerful illumination than any previously used. Since Sir William Siemens's death, Frederick has suc- ceeded him in the management of that branch of the 14 [CHAP. II. PARENTAGE AND FAMILY. business connected with furnaces and heat applications generally. The sixth son, Carl Heinrich, was born in 1829. He does not come much into the foreground as an inventor, but he stands distinguished for the energy and practical skill with which he has co-operated with his brothers. He had a share in founding all their large commercial undertakings, of most of which he is part proprietor. In 1853 the Berlin firm had undertaken the construction and twelve years' maintenance of a great system of tele- graphs throughout Russia, and this led to the establish- ment in 1855 of a large branch factory at St. Petersburg, which was at once taken charge of by Carl. In 1869 he went to London, and took up actively his position as one of the partners in the electrical works there. Some years later he was engaged in the laying of the Direct United States Cable, in the ship "Faraday." In 1880 he returned to Russia, where he still resides. He has received many acknowledgments of his merits, in orders from various sovereigns. The seventh son, Walter, born 1832, was Prussian Consul at Tiflis, and had the direction of large mining works in the Caucasus belonging to Werner and Carl. He also took part in the establishment of the Indo-European Telegraph, and managed a branch of the telegraph-manufacturing works established temporarily at Tiflis in 1863. He was accidentally killed by the kick of a horse in June, 1868. The eighth son, Otto, born 1836, took Walter's place, but he was very delicate, and died in 1871. CHAP. II.] 15 BROTHERS AND SISTERS. Of the two daughters who lived to adult age, one, Mathilde, the eldest of the family, married, in 1838, Herr Himly, an eminent scientific man, Professor of Chemistry at the University of Göttingen, who had afterwards much to do with William and other members of the family. Herr Himly was appointed in 1846 to a more prominent position at the University of Kiel, where his wife died thirty years later. The other daughter, Sophie, the youngest child but one, married Dr. Carl Crome, of Lübeck, who, in 1875, was one of those called to be Reichsgerichtsrath in Leipsic. It will be gathered from the preceding notices that four of the brothers, Werner, Williaıı, Carl, and Friedrich, were brought much into business relations with each other, and it may be added that (a circumstance not invariably pre- vailing in such combinations) they worked at all times most harmoniously together. Indeed, it is often now difficult to define what was the precise personal share either of them had in the many great inventions for which the world is indebted to them. It may, however, be said that, in elec- trical matters, Werner, William, and Carl were principally associated, while in the metallurgical inventions Frederick was William's chief coadjutor. There was a strong general and mutual feeling of affection and respect existing throughout the family. This was shown on the occasion of the marriage of a grand- daughter at Lübeck in 1871, when all the members of the family attended who could possibly do so. They took the opportunity of visiting Menzendorf, and of joining hands round the parents' grave, an affecting and appropriate address being delivered at the same time by Professor Himly. 16 [CHAP. II. PARENTAGE AND FAMILY. It is also worth mentioning that a remarkable Siemens Stift was founded some years ago for the promotion of general good feeling in the family, and for the benefit of those among them who were not in prosperous circum- stances. It was arranged that once cvery five years all members of the Siemens family, rich and poor, of direct descent, should, if possible, meet at a certain pleasant locality in the Harz mountains, and pass a day or two together in social intercourse. At the same time the affairs of any applicants for help were inquired into, and relief was, in all deserving cases, afforded out of a fund kept up by the subscriptions of the more wealthy families and indi- viduals. William twice attended these meetings, which in some cases were so large as to fill an entire hotel. CHAPTER III. YOUTH AND EDUCATION. Age to 19. 1823 to 1842.

CARL WILHELM SIEMENS was the seventh child, and the fourth of the sons who lived to an adult age. He was born at Lenthe on the 4th of April, 1823. It is not unusual, in Germany, when several baptismal names are given to a boy or girl, to repeat one name already borne by a brother or sister. In this family, another brother, born six years afterwards, was also named Carl, and the elder one was thereafter usually designated by his second name only. After his naturalization in England, the German names became Charles William, and although he signed with the initials C. W., he preferred to be called, as in his youth, simply William. He was a fairly strong and healthy child, although some- what delicately organised, and he manifested, as an infant, C 18 [CHAP. III. YOUTH AND EDUCATION. a very affectionate and sensitive disposition. While he was "the baby" of the family, and the constant companion of his idolized mother, he was noted for merrily singing about the house; but on the birth of the next child, his grief was so great at being supplanted in his position that his song was heard no more. This sensitiveness was further shown some years later, when the joking of his playmates on his red hair annoyed him so much as to produce, it was thought, a marked reserve and shyness in his behaviour. There is no record of his having shown in early life any partiality for mechanics, or of his having found any plea- sure in the observation of mechanical objects or con- trivances. He made no pigmy windmills, sailed no model boats, did not damage the furniture by baby-carpentering, or pull the clocks to pieces to see how they were made to go. In short, the child was in no way the father of the man who became one of the best mechanics in the most mechanical country in the world. The only way in which he gave any sign of his future powers was by a careful and attentive observation of men and things, which was manifested very early; for while almost an infant he was fond of roaming about alone in the fields and watching the labourers at their work from any place of concealment he could find. His brother Werner relates that one day in the harvest time, William, then only three years old, was missing when the family assembled in the evening. This naturally created great alarm, and dili- gent search was made for him, but without success. At the customary breakfast hour, however, the next day, William appeared, complaining of cold, but otherwise very comfortable. He had been hiding in a hedge to watch the men in the field, had fallen asleep, and only awoke at daybreak. The freedom from fear or uneasiness, manifested by the child at such a tender age, showed signs of another CHAP. III.] 19 SCHOOL AT LÜBECK. quality which distinguished him in after life, namely, self- reliance and independence of character. The first instruction he had was from a resident tutor at Menzendorf, along with his elder brothers, Werner, Hans, and Ferdinand. But the time soon arrived when it was necessary to think seriously of their prospects for the future, and the parents seem in this matter to have consulted and fallen in with the wishes of the boys themselves. Werner had expressed a liking for a military career, and he was accordingly allowed to enter the Artil- lery Corps, while Hans and Ferdinand preferred to remain in their father's occupation, although the former left it at a later period for the more stirring life of a manufacturer. When it came to William's turn to decide, we find again no inclination shown for anything analogous to his ultimate destination; he elected to devote himself to mercantile pursuits, and as an appropriate preparation he was sent to a school in Lübeck, called the Von Grossheim school. It was a Kaufmann- or Handel-Schule, or what in England would be called a "Commercial Academy," where a good, plain education was given, but without any attempt to impart refined literary or scientific attainments. A curious evidence of the boy's power of observation at this time was shown in an address given in the last year of his life, where he described in great detail the constitution of the German Trade Guilds, which he had made himself acquainted with in these Lübeck school days. On the 26th July, 1838, the mother wrote to Werner: What is to become of Wilhelm we do not know; we cannot at present settle him in Lübeck. Ferdinand [an uncle] has taken much trouble, but he can find nothing suitable for him. We have written to our cousin in Cologne, and perhaps he may go there. C 2 20 [CHAP. III. YOUTH AND EDUCATION. This application was acceded to, and it was accordingly settled that William should go as a pupil to the firm of Messrs. Deichmann, bankers of Cologne. But before this arrangement was carried into effect, Werner paid a visit to his parents, and the subject of William's future career was again discussed between them. Werner had taken a great liking to this younger brother, and interested himself strongly in his welfare. He appears to have doubted whether the proposed occupation of a merchant was a desirable one for him, and wished to have the matter reconsidered. Since the choice had been made Werner had seen much more of the world; his mind had become enlarged, his views extended. He had been for two or three years studying scientific and mechanical subjects in the Artillery School, and a vista was opening to him of a vast field of profitable occupation that might be found in the technical applications of science to industry. Moreover he, with acute penetration, saw what had hitherto escaped the observation of William's parents, and had probably been unsuspected by William himself, namely, that he possessed mental qualifications which would, when properly cultivated and encouraged, ensure for him success in scientific and mechanical pursuits. He accordingly laid these views before the parents, and after some hesitation on their part he succeeded in inducing them to allow William to consider the propriety of giving up the mercantile prospect, and of preparing himself for a mechanical career:-Techniker zu werden, as it was expressed in German ;-in other words, he proposed to make him an engineer. It does not appear that William himself shewed any strong feeling in the matter either one way or the other ; but he had great respect for his elder brother's judgment, CHAP. III.] 2 I SCHOOL AT MAGDEBURG. and possibly he began to be better aware of his own qualifications than formerly. At any rate he agreed to Werner's proposal. Having gained this point, Werner determined to bring his brother under his own immediate care. He had just been appointed to service in the garrison of Magdeburg, and he arranged that William, who was now fifteen years of age, should at once leave Lübeck, and go to a Gewerbe- Schule (industrial school) at Magdeburg, where Werner could observe and control his education. He accordingly went there at Michaelmas, 1838, and entered on a course of instruction of a more advanced description, including the general principles of natural science, which Werner was most anxious he should acquire. But Werner had still further views and plans for his brother. He wished not only to qualify him for scientific occupation at home, but to fit him in a certain degree for intercourse with strangers abroad, and he decided that he ought to learn foreign tongues. French was included in the Magdeburg school course; but Werner was not satisfied with this, and he resolved that William should straightway begin to study the English language. But he found that, although English was taught at the Magdeburg School, it could not be included in William's course without omitting some other subject which it was important for him to learn. To get over this difficulty, Werner arranged that the omitted subject should be mathematics, which he would contrive to teach the boy himself. In this way William studied mathematics under Werner's tuition in the early morning hours, before the opening of the school and the commencement of military duty. And so successful was this arrangement that when 22 [CHAP. III. YOUTH AND EDUCATION. the examinations came on, William passed in mathematics with a high certificate of proficiency. The change, however, was not altogether satisfactory to the parents. On the 24th December, 1838, the father wrote to William as follows: I have been sorry to see that you are put into the third class. How long will it be before you get into the first, and how did it happen? Do your utmost to get out of it by Easter. I really do not understand the school. No English in your class! and only two or three hours a week for French. You ought not to trouble yourself much about things which can be afterwards learnt by lectures or reading, so easily and pleasantly. Languages are the most important things for you; with these, arithmetic and natural sciences, and also the mercantile knowledge proper. I am anxious to hear, now you have full information, how the time in the school is appropriated. I send you herewith 50 Reichsthaler (£7 10s.), and hope you have not long been in difficulty. I should have preferred that you had been in a respectable and good house, boarding entirely; soldier-life is not good for you [alluding to his being so much with his brother Werner]. Much may still be arranged. Take care of your most valuable time; be frugal and economical, but without denying yourself anything absolutely necessary. If you find pleasure in follies, and in anything beside improving your mind, you will come to nothing. * What sort of a fellow is Siemens's son? How comes it that he, in his sixteenth year, sits only in the third class? Is he wanting in brains? Now farewell, my dear son; become an able, capable fellow, then will it surely go well with you in the world; but otherwise- Dein treuer Vater, C. F. SIEMENS. Soon after this the first great grief of William's life came upon him by the death of his mother, whom he passion- CHAP. III.] 23 MOTHER'S DEATH. ately loved. She was comparatively young, only 46, and was naturally healthy; but the trial of bearing fourteen children in quick succession, combined with the domestic cares of rearing them and of her household affairs generally, had broken down her constitution, and she became subject to nervous disorders. She had been ailing for some time, but in December, 1838, her husband stated she was getting better; and again, on the 3rd April, 1839, he wrote to Werner :- I can give you good news of your mother's health. She has improved daily, and will probably soon be perfectly recovered. But this hope was delusive; she became rapidly worse, and after much suffering she died on the 8th of July. The following letter was written by the father to Werner a fortnight after her decease; and it contains the first positive indication of the failure of his own health also. He had been always considered a strong man; he was then in the prime of life, and in his letter of the 24th December, 1838, he had said, "We are perfectly well." DEAR WERNER, 16th July, 1839. I pity you sincerely, on account of the mournful news that I have to give you. You both know, I am sure, what a rich capital of affection the dear departed one had invested in you. A I can yet hardly collect myself, probably on the ground that my health is not yet restored. The cough, palpitations of the heart, the constantly increasing pulse, the disturbed circulation, caused by every little exertion, and the incredible weakness, will not abate, but have, in this great excitement, become worse. slow walk through the garden lays me in bed. When I feel strong enough I will ask Dr. what my state really is; for the first time in my life I am anxious about it. For (horrible to say) if I do not live to be seventy years old, I shall have to leave helpless orphans behind. in 2 24 [CHAP. III. YOUTH AND EDUCATION. I must confess that it is a comfort to know that the dear departed one is free. For in her state there was no hope, and a longer life would only have implied a longer suffering. I should like to see you here, for I want more accurate news about William. I should like him to make a journey to Colleda and the Harz. He spoke further of domestic difficulties, of the failing of his crops through bad weather, and of the scarcity of money, and ended :— Now farewell, dear son; let me soon see something of you, and do not use such a thick envelope, which makes your letter cost a-half extra postage. C. FERD. S. By the same post he wrote to William, but in quite a different strain. He said not a word about the mother, or about troubles of any kind; but seemed desirous to inspirit him for his contemplated journey to the Harz, by telling him some of the historical legends, of which he had in his memory an ample store. The close of his letter is also very characteristic of his literary taste. DEAR WILLIAM,- 16th July, 1839. I shall be glad if you can make a journey to Colleda [in the Harz mountains], and make the acquaintance of my old brothers and sisters. Your uncle Augustus is an excellent man ; aunt Gretchen has always been considered by everyone as the crown of her sex, and I have for a long time loved and honoured her. .Coming back you may pass by Sachsenburg, Frankenhausen, and the Kiffhäuser. There Friedrich Barbarossa has lived long, and lives yet in the popular legend: there sits he still in the heart of the mountain, and sleeps; and his red beard is grown through the stone table; and he will wake up and again seize his mighty Kaiser-sword, when Germany's disgrace has reached its utmost limit. CHAP. III.] 25 FATHER'S LAST ILLNESS. There also his faithful esquire, the Smith Poltermann, from Jüterbog, the discoverer of the scythe, bustles about and brews his beer, as may be seen in the steam and fog caps to the summits of the hills foretelling changes of weather. Also, if you have time enough, visit the Mendeben Monastery, the still greater monument of German greatness. This was the customary halting place of Henry I., and of the great Otto, from which time there has been nothing but disgrace and misery in Germany. I have never seen this place without painful emotion. Do you not know the great importance of punctuation both in speaking and writing? Your manner of writing is, in this respect, almost ridiculous. You may learn this from a housemaid or from a crossing-sweeper. You make commas where full stops ought to be. The shorter the periods, the rounder the ideas; the more full stops, the more precise and concise, and consequently the clearer and better, is the style. You make also many blunders in spelling, and show no signs of instruction in the German language. The following, addressed to William, is the last of the father's letters that has been preserved :- DEAR SON,- MENZENDORF, 12th Nov., 1839. Now that I am at last able to do so, I send you some money. I have never been in such want of funds as in this autumn. I have often thought of you with sorrow. I would willingly have sent what you will want till Easter, but I shall be only too glad if I get through the time myself. * * * ※ In August I was stronger, but the melancholy and care threw me back again. The most cruel cough and pain in the chest have confined me to my bedroom for three weeks. I believed I should not last longer than until the appearance of the snowdrops; but the pain and the fever have abated.

The young ones are all happy. been of considerable help to you. your future in view. Greet Werner, who must have Answer soon, and keep always Dein treuer Vater, C. F. SIEMENS. The poor broken-hearted man did not even live to the time he had so pathetically allotted himself; he never saw the harbingers of spring; he died, aged only fifty-three, on the 16th of January, 1840. This sudden break-up of the household caused deep anxiety in regard to the prospects of the family, for the father had left his affairs in by no means a prosperous condition. The eldest daughter had married shortly before, but the other nine children, some very young, were but scantily provided for. In this strait the duty fell on the elder sons to take care of the younger children; and Werner, with great courage and devotion, although then only twenty-three years old, constituted himself the chief guardian of the family. To William his care became more tender than ever, and he now proposed to improve his scientific knowledge by sending him to the University of Göttingen.* He was encouraged to do this by the fact that his eldest sister had married Herr Himly, Professor of Chemistry there. The idea, indeed, had originated with her, for in a sad letter, written by her to Werner in September, 1839, immediately after their mother's death, she said :- Give my hearty greeting to William; if he remain so good and industrious, God will surely help him forward. I think, in his present circumstances, it would be advantageous for him at some * This is Werner's account, furnished to the author. William him- self, in 1882, described his going to Göttingen as "an act of rebellion against his guardians." See page 347. CHAP. III.] 27 SCHOOL AT MAGDEBURG. future time to attend lectures in Himly's subjects, and I often take a quiet pleasure in anticipating that he could then stay a winter or longer with me. This invitation was not forgotten, and after due consul- tation with the influential friends of the family, it was now taken advantage of. It happened that in addition to his sister another near relation also lived there, who had married the Colonel Commandant of Göttingen, Lieutenant von Poten, and it was anticipated that the high social intercourse he would obtain through the families of these relatives might fit and prepare him for cultivated society in after life. He accordingly left the Magdeburg School at Easter, 1841. His certificate of dismissal, dated the 25th March in that year, is still preserved, and it gives him an excellent character. He had long before got himself removed (according to his father's exhortations) into the highest class, and he had, in addition to the ordinary course of education, become fairly proficient in algebra, geometry, trigonometry, and physical and technical subjects. He had also acquired some knowledge of the French language, and his German style was pronounced fluent, and not with- out richness of idea, although not always strictly correct. He had been studious and persevering, and his behaviour had earned the praise of all his teachers. At the same time, the facilities at this Magdeburg School for acquiring a knowledge of physical science were very scanty compared with those generally provided in labora- tories now; and Sir William Siemens has himself stated that, on carrying his thoughts back, it would almost seem impossible that anything efficient could have been taught there. For example, the appliances then at his command for acquiring the rudiments of electricity were of a very 28 [CHAP. III. YOUTH AND EDUCATION. primitive kind: they consisted of a battery, composed of flannel and some pieces of copper piled up to a certain height, so as to produce a spark; and also an electrical friction machine, such as may now be seen in an advanced nursery. For mechanics there was a long scale with a pulley to show the acceleration of a body by gravitation. These formed the only scientific apparatus then existing at the Magdeburg Gewerbe-Schule.* After a visit to Menzendorf he went to Göttingen, enter- ing on his studies there on the 10th May, 1841. He attended lectures by Professor Hausmann, on physical geography and technology; by Professor Stern, on the higher mathematics; by Professor Wöhler, on theoretical chemistry; and by Professor Himly, on practical chemistry and physics. He also obtained admission to assist, for a short time, in the observations in the magnetic observatory of Wilhelm Weber. The following letter from Werner will illustrate the nature of William's studies, and give an idea of the pro- gress made :- MAGDEBURG, 26th June, 1841. Your letter has given me much pleasure. I almost envy you this fine opportunity of acquiring knowledge, but I am convince: you will use it to the best possible advantage. Your leisure hours will be employed in the pleasantest way by association with our dear sister, with Himly, and our other relations; and what can you, for the moment, desire further? In regard to the occupation of your time, I am only dissatisfied with the absence of drawing. You must certainly have instruction in this, for it is the most essential foundation of your proposed occupation, which you must on no account delay, for you are very backward in it. If you cannot get a good teacher, study from good text-books on the subject, and practise for yourself, espe- cially geometrical projection. * "Creators of the Age of Steel,” p. 136. CHAP. III.] 29 AT GÖTTINGEN. It would also be very profitable for you, if possible, to do some practical work, as it would much facilitate the conditions necessary for finding you a situation. If nothing happens to the contrary, you can stay for a year, and we can seek, at Easter, a favourable position for you in a machine factory. Your principal studies must now be mathematics, particularly in the applied branches, physics, and drawing; it would be good for you to hear some lectures on machinery, but I doubt if you can find them in Göttingen. Madgeburg is a wretched hole (ein fatales Nest). Nothing is to be got here; everything is dear and bad. My experiments, there- fore, progress very slowly, as the most important materials are wanting. The cursed money is the log continually tied round one's neck. In August of the same year his sister wrote to Werner:— William is very industrious and well-behaved; Himly and I both wish him to remain here for the winter. Towards the end of the year William wrote to his uncle Deichmann, who had charge of the money arrangements, asking leave to prolong his stay, and offering to make some personal sacrifices with a view to economy. The following are extracts from Mr. Deichmann's answer, dated 18 January, 1842 :— I am very glad to learn from your letter that you take pleasure in the matter you are engaged in. Be of good courage, and work earnestly. I give you my permission, my dear William, to remain till Easter in Göttingen; make the best use of the time, and follow exactly the counsels of your good brother-in-law, then will all be well. We must have a consultation about the expense which this longer stay will involve, but, even if I have to pay it out of my own pocket, I should wish that you fully complete your education there. As to what you say about self-denial and so on, I beg you will never again let me hear such high-flown nonsense, showing that 30 [CHAP. III. YOUTH AND EDUCATION. If you you have misunderstood the circumstances of the case. like to practise self-denial after you are of full age, I have nothing to say against it; but, till then, I am personally respon- sible for your welfare, and I beg of you to do nothing without my previous knowledge, or I may get into unpleasantness. Be cheer- ful and gay; constant work dulls the mind. Fresh air, exercise, and moderate enjoyment are necessary to render study effective, as I know by my own experience. Dein treuer Onkel, G. E. DEICHMANN. In the meantime, however, his brother was anxious to get him into more active employment, for the University life was expensive, and it was desirable to look forward towards his speedily earning his own living. The results of Werner's efforts in this direction are told graphically in the following letter:- DEAR WILLIAM, WITTENBERG, 21st January, 1842. I have received your welcome letter, and hasten, in reply, to send you a Christmas present, namely, a place in an engineering machine factory in Magdeburg. In Berlin the people asked many hundred thalers as premium, even up to 500, so that would not do, and this Christmas I went over to Magdeburg. The factory there, formerly belonging to Mr. Aston, has been re-organized by Count Stollberg; and it happened that the manager, Herr Schöttler, was looking about for some pupils, also requiring a considerable premium. A friend of ours had been speaking to him about you, and when I went to him he offered to take you, being a countryman of his (he also is a Hanoverian), without premium, and for an indefinite period. I did not at once consent, as I wished to make inquiries about him and the factory. All agree that, although not very learned, he is a good practical mechanic, that the factory has turned out many new steam-engines. (about twenty in the last year), and that it is the intention of Count Stollberg to increase it considerably. I believe, therefore, that in two years you may, in this place, educate yourself thoroughly. I asked uncle Siemens to settle the CHAP. III.] 31 AT GÖTTINGEN. 1 matter with Schöttler, and I send you his letter, from which you will see that there are some very favourable conditions attending the matter. Schöttler's son has been for two years in the factory, and has become practically proficient; but he is wanting in scientific education. He is getting instruction in Magdeburg; but that does not help him much, and he wishes you to aid him in this particular. He is a very agreeable and simple-minded young fellow, and I believe this will be a very advantageous arrangement for you, as a repetition of what you have already learnt will do you no harm; on the contrary, it will bring out any true knowledge you have acquired. If you are prudent, this arrangement will give you a power over the old man. So be merry, my dear youngster, as Madame Fortune has evidently prepared you a nice warm nest there! You will enter on your position at Easter, when perhaps I can meet you. Therefore take care to make good use of the remain- ing time in completing your theoretical education, for so good an opportunity will probably never occur to you again. Be especially industrious in studying mechanics, and the application of the higher mathematics thereto. I take it for granted that you are already well grounded in the principles of physics, especially in the mechanical part of them. I believe Schöttler will, in time, give you completely free lodging and maintenance; but in the meantime your expenses need not be large, as you may accept the offered free board without scruple. In March, 1842, Frau Himly wrote again : William leads here a true student's life; I see little of him except at meal times. I am, however, convinced that he is industrious, and so I willingly let him enjoy this happy time, which will be so soon over. On the 24th of the same month he received his final Testi- monial certifying to his studies, and adding that he had been "extraordinarily industrious," and that his conduct had been unimpeachable. He now, therefore, at the age of nineteen, bade adieu to his scholastic life, and in accordance 32 [CHAP. III. YOUTH AND EDUCATION. with the arrangement made some months previously, he went to Magdeburg to begin his practical training as an engineer. A few months after this the idea was mooted of his paying a visit to England. Professor Himly appears to have had some communication with a correspondent there, which is referred to in the following passage in a letter from Madame Himly to William, dated 8th July, 1842- I have been much pleased with your last letter; I see you are a sensible young fellow, or at least you try to appear so, inasmuch as you write so calmly about the London affair. I wish I could say something more definite to you about it. My husband has at present no answer. If nothing comes of this journey, take it as an indication that such fortunate accidents happen and may often come in your way, and therefore do not swerve in your trust in Providence and in yourself. Nothing further came of this at the time, but the idea, a significant one for his future career, evidently remained in the minds of himself and his friends. The relations between William and his brother Werner had now become closer and more confidential. Ever since Werner, on the death of the parents, had taken William under his special protection, the latter had constantly relied on his wiser and more experienced brother for advice and help; while Werner, now that William was advancing towards an independent position, began to look on him rather as a valuable future colleague than as a junior and a learner. Hence arose a strong mutual desire for frequent com- munication, and when William went to Magdeburg with a possibility of remaining there some time, the two brothers CHAP. III.] CORRESPONDENCE WITH WERNER, 33 ར made a compact for a systematic correspondence to be regularly kept up between them, not only on personal and domestic matters, but also discussing scientific and technical subjects, and communicating any ideas that might occur to them, or any experiences that might fall in their way. This arrangement was maintained with more or less regu- larity throughout all the vicissitudes of the lives of the brothers. Every scientific study, every new invention or idea, every important business transaction, every private joy or sorrow, was faithfully and freely communicated or commented on, and the correspondence only ceased when the King of Terrors struck, with such fearful suddenness, the pen from William's hand. A few of William's earlier letters, written from Magde- 'burg to Werner, who had then gone to reside permanently in Berlin, are still preserved. In one of them, dated 15th August, 1842, he sent a long description of a new kind of valve-gearing, for single-acting (Cornish) steam-engines, which he had invented; it was accompanied by an elaborate drawing, probably one of his first efforts at engineering design, and he said to his brother, with great good-humour- You will look with wonder on the drawing which accompanies this letter, and will have a hearty laugh at me when I tell you that it is a new valve-gearing, invented by me, which I have a strong inclination to take out a patent for. The drawing is lost, but by the description the invention appears to consist chiefly in the substitution of slide-valves for those ordinarily used in such engines. He, however, afterwards discovered some objections to his scheme, and it went no further. D 34 [CHAP. III. YOUTH AND EDUCATION. The next letter, dated 29th August, was chiefly devoted to the discussion of an invention which Werner had laid before him, called "The Pendulum." This was none other than the "Chronometric Governor," which we shall hear so much about hereafter. William began by saying- Your Pendulum seems to me of great importance for large steam-engines, both of high and low pressure, such as are found in manufactories and workshops, since these have a uniform motion, and require to be accurately regulated. But it would be difficult to apply to small engines, or to those which are single- acting. He then went into a detailed examination of the arrange- ments, stating several objections and proposing several improvements. He offered to make some small trials himself, and spoke of consulting some persons apparently engaged in the same factory. He said- I would not do much, for that would cost a deal of money, and might lead to nothing. I would not attempt to convert un- believers, if only one believer can be found who will provide the means. I would not show it to S- who has a curious obtuse- ness, and I have said little to M- for I found the whole set of them yesterday in a fierce wine-orgie, the very floor of the room testifying to their state. " My opinion is that we must at first seek only a small profit, if such is possible, in order to cultivate the Pendulum with more energy. A third letter, dated 12th September, spoke of a probable trip to the Harz mountains— Where we can be in the highest degree confidential with each other; for I have so much on my mind, which I cannot say in letters, even if I had patience enough to write it; and so would it be with you. The letter contained further remarks on the steam- CHAP. III.] 35 ELECTRO-GILDING. engine and the governor, but it is chiefly important on account of its reference to a new subject which was to be of great interest in his life. A year or two earlier Werner Siemens (as has been already mentioned in Chap. II.) had devoted some attention to the application of electricity to the processes of gilding and silvering, in which he had been aided materially by his brother-in-law, Herr Himly. He had taken out a Prussian patent for the process, and had established in Berlin a workshop for putting his inventions into practice. Werner had been in communication on this subject with William, and had urged him also to devote some attention to it, as likely to be profitable. William took the hint, and in this letter he said :— I have now been going on with the gilding work. Everything has succeeded with such startling rapidity that my expectations have been exceeded tenfold. The salts, which had become dry, dissolved immediately, and the first spoon dipped therein became perfectly and beautifully gilt in a minute, and half-a-dozen more followed. The little battery is so powerful that each single ele- ment gives lively sparks, and the magnetic-needle, with six coils, shows 75° deviation. The lamp also answers well. It seems to me you should exert yourself to sell the patent-right in other districts, so as to obtain profit elsewhere as well as here. He also spoke of a little artistic work he had been doing privately, namely, painting, for the wife of the manager, a landscape of Nordhausen, which he described as very cunning (höchst knifferlich). It is needless to reproduce here the elaborate mechanical details given in these several letters; but they are significant as showing the talent and capacity of the writer. They evince an acuteness of perception in mechanical matters; a power of close and correct reasoning; a sound judgment, a fertility of invention, and an ease and accuracy of expres- D 2 36 [CHAP. III, YOUTH AND EDUCATION. sion, which, in a youth of nineteen, who had only had a few months' experience in a workshop, are extraordinary, and undoubtedly shadow forth the brilliant future he attained in the engineering world. At the end of the year 1842, William paid a visit to his sister at Göttingen; and while he was there, Werner, who had been meanwhile transferred to a command at Berlin, wrote him a letter, dated 13th December, from which the following passages are extracted :- Your letter has given me great pleasure. It is good that you have made such great progress in working at the lathe. I should like to know whether you do turning in iron or only in wood?— the former is the more important for you. You may send me some pretty little specimen of your work, partly for my own satis- faction, and also that I may exhibit it to others. But do not neglect your drawing. Also keep up your studies of physics, mathematics, and the nature of machinery; the latter is ex- ceedingly important for you. The original intention was that William should remain for two years at the Stollberg factory; but his progress had been so rapid that Werner seems to have been inclined to abridge the time by one-half; for he goes on to say:- I will look out for some employment for you, both in Magde- burg and in Berlin; for at Easter you must begin to practise your new calling. As soon as I know anything certain, I will write to you. Perhaps you can obtain in Göttingen some recommenda- tions to a manufactory or to some influential person. Try to do this, as it would be very useful. Matilda writes me that you have made great progress in your appearance and manner. That delights me much, for you can hardly believe, my dear brother, what a powerful recommendation to all men exists in a free, manly, and unembarrassed address. The dancing lessons seem to have been useful to you; perhaps there lay eine kleine Liebschaft therein ? Or are you still fixed in CHAP. III.] 37 MEANS OF INCOME. Kölleda? If a furlough was not so difficult to get, and travelling was not so cursedly dear, I might pay little Minna a visit. But then you would be jealous! Farewell, dear brother, and forget not Deinen treuen Bruder, E. W. SIEMENS. Between this time and Easter modifications of Werner's plans had begun to set in. His electro-plating operations had answered well, and his active mind had contemplated a large extension of this trade, as well as the introduction of many other inventions, chemical and mechanical, which he conceived might be profitable. He and William had discussed these together in their correspondence, and the latter had contributed to the discussion the results of his newly-acquired experience in mechanical construction. But Werner was hampered by his military position and duties, which he dared not resign, as the pay was very important to him. Indeed the necessity of making more money was now very strong; the younger children were growing up, and were becoming daily a more onerous charge upon the elder ones. Werner therefore saw that some means of income must be found beyond what would be furnished by the Lieutenant's pay of one, and the small salary which the other might obtain in a machine factory. The hope seemed to lie in the energetic pushing of the inventions of the brothers, particularly the electro-deposit- ing processes; and it occurred to Werner that it might be advisable to revive the idea of William undertaking a journey for this purpose. He had consulted Herr Himly again about this, and in October, 1842, his sister wrote:- You seem to expect much from this gilding; but it is already very common. Himly is of opinion that William has not much to hope for in the large towns, where the people are advanced in 38 [CHAP. III. YOUTH AND EDUCATION. their knowledge. For example, the Elkington processes in London are probably very good. This early mention of the Elkington firm is singular, comparing it with what afterwards occurred. It is clear that at that time there was no idea of making a definite application to them; probably Herr Himly, in the course of his chemical investigations, had heard of the English manufacture, and mentioned it only casually. In spite, however, of his discouraging hints, Werner determined that the effort should be made, and it was accordingly arranged that William should get a temporary leave of absence from the Stollberg factory, and should undertake a journey, beginning with Hamburg, and going on, if possible, to England. The result of this will be told in the next chapter. + CHAPTER IV. FIRST YEARS IN ENGLAND. Age 20 to 28. 1843 to 1851.

WILLIAM started on his journey early in February, 1843. He was first to pay a visit to Menzendorf, after which he was to go on to Hamburg, his further proceedings being regulated by what he might do there. He took with him. samples of his stock in trade, namely, an electric battery of peculiar construction, and certain solutions for metallic deposition. He hoped, by exhibiting these, to show the value of the improved processes, and to effect sales of the right to use them. His first proceedings were told in letters to his brother Werner, which still exist: they were written in excellent spirits and with much enthusiasm, and they abound in jocose language, much of which loses its point in trans- 40 [CHAP. IV. FIRST YEARS IN ENGLAND. lation. The following extracts will tell all that is necessary for this history:- HAMBURG, 21 February, 1843. For the last two days I have been running about, in the hope of being able to do business; but the people here are worse than in Berlin, and I may probably have to leave the place unsuc- cessful. Early this morning I had a sort of half-and-half offer; I asked sixty louis-d'ors, and the man agreed to call on me and see the thing. I unpacked my solutions and apparatus, and brought the whole into proper order. In the afternoon he came to the inn with his stupid blank face (mit flauem Gesichte), but he soon went away blanker still; for the battery, which had worked ad- mirably before his arrival, suddenly seemed bewitched, and failed in its action. You think I ought to visit Holland, but there it will probably be worse than here. My opinion is, that England is the place if anything is to be done. He was, however, more fortunate in Hamburg than he anticipated, as his next letter showed- February 22nd. At last I have found out the right person. There lives here, quite hidden from the world, a fellow who has a tolerably large manufactory of metallic window-frames and such like. He has ordered from Rössler a considerable quantity of solutions, with a battery; but these are not sufficient for him, as he requires to treat articles of brass or cast-iron, 12 feet long, 2 feet wide, and 40 lbs. weight. I have undertaken to put him in the way of accomplishing his object, and for this service, which will occupy me a week, I have asked ten louis-d'ors, and my offer has been unconditionally accepted. He was especially pleased with the cleanliness and simple action of my battery. If I had not been a simpleton, I might have got from him eight louis more, for he now fears I may make the process known elsewhere. ! A formal contract was entered into between C. W. Siemens and the manufacturer, Herr J. D. Klopfer, on the CHAP. IV. 41 BUSINESS IN HAMBURG. 26th of February, ratifying this agreement. It is still preserved, and is a well-drawn explicit document, showing a fair business-like capability on the part of the young engineer. The letter continued:- My stay here costs little, for an old acquaintance from Lübeck has invited me to stay with him. As the crossing from Hamburg to London costs only £1, it will certainly be best to devote to that journey the money made here; and then, even if the speculation fails, my ardent wish to see England will have been fulfilled. If your new solutions give good results, send me, without delay, a large grand-looking specimen (einen grossen recht pompösaussehenden Gegenstand), and I shall not start for England till I hear from you. If the thing succeeds I will try to remain in that country (wenn es irgend geht, so will ich mir in England einen Anhalt zu verschaffen suchen). This mention of England as a probable permanent resi- dence is very significant. He also gave some impressions of the great fire which had desolated Hamburg in May, 1842, and added some remarks on the general life in the city. It is interesting to follow the course taken by the fire, but the impression which the view made upon me is not so great as I had anticipated. One sees too little of it at one time and from one place. It is remarkable how the new Bourse with a dozen houses in the square have remained, while massive build- ings, and even the churches, have been burnt to the ground.. A badly built wooden house has also been left standing in the middle of the conflagration, as if the fire did not think it good enough to attack; otherwise it would have burnt like a torch. The life here is much more original than in Berlin. The fullest provision is made for intellectual enjoyments. I am especially pleased with the free manner of thinking, and the independence of the Hamburg citizens. In all the beer-houses political matters are freely spoken of; the high and learned councillor is put down, 42 [CHAP. IV. FIRST YEARS IN ENGLAND. if need be, by the plain citizen, even if ten of his fellow coun- cillors are present. So is it also that in all public meetings and concerts where ladies go, the Hamburger keeps his hat on, while the unmarried ladies remove their head-covering. In the same letter he gave to his brother an account of what he had found at Menzendorf, where the family were still remaining after the parents' death. He says:- Hans lay, when I left, ill with a severe rheumatic fever; the poor fellow could not move a limb, and his brother Ferdinand was obliged to lift him, like a mass of boneless flesh, in and out of bed, which required a herculean power to do without hurting him. Ferdinand had also otherwise distinguished himself, and is a good practical farmer. Friedrich and Carl are, in heart and soul, sailors; the young ones are somewhat backward in their learning, chiefly from the fact that at home they have no place to study in, but are driven with their books from one corner to another. I have little to say about Sophie [then seven or eight years old] as she has enclosed a letter to you; she is very pretty and clever, and can play at chess already. It is unfortunate, however, that there is no rod in the house, which might do her considerable good! Walter and Otto are smart youngsters, and will, it is to be hoped, go to school at Easter; grandmother [the mother's mother] is as vigorous as ever, and the household arrangements suit her very well. Menzendorf is, I am thankful to say, to be given up in the spring; there are many speculators ready to give for it the price asked, namely 10,000 dollars. Werner answered the letter from Berlin, the 27th February, saying that, in consequence of illness and other disappointments, the electro-depositing work had not gone on so well, and adding further instructions :- If you go to England you must ignore colour, &c., and confine yourself to the simple plating-holding out the advantages of quicker and cheaper work . . . Give up beauty of gilding, and rely on durability, which is especially suited for that country. CHAP. IV.] 43 BUSINESS IN HAMBURG. Before all things you must have money; I have been long con- sidering how this is to be managed, and I will write to Uncle Ferdinand in Lübeck, to lend you 100 thalers. See if you can- not get something extra in Hamburg by offering some of the pro- cesses, you may thus obtain 10 or 15 louis-d'ors more. I wish you new success and open eyes in England. You must write to Schöttler, and say you have not finished your business, but will return soon. On the 9th of March William sent another letter, explain- ing that the reason of his long stay in Hamburg was the necessity of sending to Berlin for some materials, and add- ing that the apparatus he had sold to the window-frame maker had been perfectly successful. The battery was very powerful, and the deposition of copper in vessels 14 feet long went on admirably. He added:- I am now so far advanced as to be able to leave by steamer to- morrow morning. You had better not send to Uncle Ferdinand, for it may perhaps be inconvenient to him to spare 100 thalers out of his business, and it is not now necessary, as my window-frame maker will give me 12 louis-d'ors for the solutions. He has not purchased the gilding and silvering processes, as the affair has already cost him 500 thalers, but I have sold him certain articles which I do not want, and could not take over to England, for five louis-d'ors. I have therefore taken a passage ticket to London, and to-morrow morning at eight o'clock I shall be on the way. I have received nothing from Lübeck, and I hope I shall not want it, although I dare not spend in all more than six louis- d'ors in England, in order to be able to return with honour back home. Uncle Ferdinand has given me good letters of introduction, and if you can send me any others, pray do so immediately. Now, dear brother, I must close, for I have yet much to do. I will write from London, but do not let me wait long before hearing from you. Dein treuer Bruder, W. SIEMENS. 44 LCHAP. IV. FIRST YEARS IN ENGLAND. He must have arrived in the Thames about the 12th of March, 1843, and he took up his quarters in a little inn called the "Ship and Star," at Sparrow Corner near the Minories. He often in after life referred with pleasure to this his first introduction to England, and he gave publicly the following account of it in an Address delivered, as President of the Midland Institute, in the Town Hall, Birmingham, on the 28th of October,* 1881. He said :— That form of energy known as the electric current was nothing more than the philosopher's delight forty years ago; its first appli- cation may be traced to this good town of Birmingham, where Mr. George Richards Elkington, utilizing the discoveries of Davy, Faraday, and Jacobi, had established a practical process of electro- plating in 1842. It affords me great satisfaction to be able to state that I had something to do with that first practical applica- tion of electricity; for in March of the following year, 1843, I presented myself before Mr. Elkington with an improvement on his processes which he adopted, and in so doing gave me my first start in practical life. Considering the moral lesson involved, it may interest you, perhaps, if I divert for a few minutes from my subject in order to relate a personal incident connected with this my first appearance amongst you. When the electrotype process first became known it excited a very general interest ; and although I was only a young student of Göttingen, under twenty years of age, who had just entered upon his practical career with a mechanical engineer, I joined my brother Werner Siemens, then a young lieutenant of artillery in the Prus- sian service, in his endeavour to accomplish electro-gilding, the first impulse in this direction having been given by Professor C. Himly, then of Göttingen. After attaining some promising results, a spirit of enterprise came over me so strong that I tore myself away from the narrow circumstances surrounding me, and landed at the East End of London with only a few pounds in my pocket and without friends, but an ardent confidence of ultimate success within my breast. * See page 343. CHAP. IV.] FIRST PROCEEDINGS IN ENGLAND. 45 I expected to find some office in which inventions were ex- amined into, and rewarded if found meritorious, but no one could direct me to such a place. In walking along Finsbury Pavement I saw written up in large letters, "So-and-So" (I forget the name), "Undertaker,” and the thought struck me that this must be the place I was in quest of; at any rate I thought that a person ad- vertising himself as an "Undertaker" would not refuse to look into my invention, with the view of obtaining for me the sought- for recognition or reward. On entering the place I soon con- vinced myself, however, that I came decidedly too soon for the kind of enterprise there contemplated, and finding myself con- fronted by the proprietor of the establishment, I covered my retreat by what he must have thought a very lame excuse. By dint of perseverance I found my way to the Patent Office of Messrs. Poole & Carpmael, who received me kindly, and provided me with a letter of introduction to Mr. Elkington. Armed with this letter, I proceeded to Birmingham to plead my cause with your countrymen. In looking back to that time, I wonder at the patience with which Mr. Elkington listened to what I had to say, being very young, and scarcely able to find English words to convey my meaning. After showing me what he was doing already in the way of electro-plating, Mr. Elkington sent me back to London in order to read some patents of his own, asking me to return if after perusal I still thought I could teach him anything. To my great disappointment I found that the chemical solutions I had been using were actually mentioned in one of his patents, although in a manner that would hardly have sufficed to enable a third person to obtain practical results. On my return to Birmingham I frankly stated what I had found, and with this frankness I evidently gained the favour of another townsman of yours, Mr. Josiah Mason, who had just joined Mr. Elkington in business, and whose name as Sir Josiah Mason will ever be remembered for his munificent endowment for education. It was agreed that I should not be judged by the novelty of my invention, but by the results which I promised, namely, of being able to deposit with a smooth surface 30 penny- weights of silver upon a dish cover, the crystalline structure of the deposit having theretofore been a source of difficulty. 46 [CHAP. IV. FIRST YEARS IN ENGLAND. In this I succeeded; and I was able to return to my native country and my mechanical engineering a comparative Croesus. By dint of a certain determination to win, I was able to advance step by step up to this place of honour, situate within a gunshot of the scene of my very earliest success in life, but sepa- rated from it by the time of a generation. But notwithstanding the lapse of time, my heart still beats quick each time I come back to the scene of this, the determining incident of my life. Through the kind offices of Messrs. Elkington, and with the aid of some other documents, further particulars of this transaction may be added. Mr. Siemens had received from his uncle in Lübeck an introduction to a firm of merchants in Birmingham, and, hesitating to go directly to Messrs. Elkington, he applied to them in the first instance through this firm. The following letter states what happened. BIRMINGHAM, 21 March, 1843. We had to-day a long interview with Mr. Elkington about your new invention for gilding, &c. He has not been able to decide anything, for the following reasons:- 1. He says that if you gild by a galvanic battery, you will run the risk of infringing his patent. 2. He cannot see that your method has any advantages over his own, except that you can gild without damaging the polish or the objects. 3. He says that you ask much too high a price, as it is only for an improvement and not for any invention. He cannot, however, decide whether he will or will not purchase. If it is only an improvement, he is ready to treat, but he must know more about it, and wishes to see some specimens of what you have done. In short, we advise you to come here and bring your apparatus; otherwise you can do nothing with him. Hoping to see you as soon as possible, we are, with friendly greetings, BEACH AND MINTE, To Mr. W. SIEMENS, Ship and Star," Minories, London. CHAP. IV.] 47 APPLICATION TO ELKINGTONS. He Mr. Siemens took this advice, and went to Birmingham to see Mr. Elkington, as mentioned in his statement. afterwards examined the patents and discussed the subject fully by letter with his brother in Berlin, the result being that he revised his modes of operation, and so far satisfied Messrs. Elkington that they authorized him to take out a new patent at their expense. This patent was issued on the 25th of May, 1843 (No. 9741) in the name of Moses Poole, being " a communication from abroad." The title was for "Improvements in the deposition of certain metals, and in apparatus connected therewith," and the specification was duly enrolled on the 25th of November in the same year. The invention consisted in the employment of certain new solutions of gold, silver, and copper for the purposes of electrical deposition, and in the application of what the patentee called a "thermo-electrical battery" for deposit- ing the same. This battery consisted of alternate vertical bars of German silver and iron connected together in the usual way, and inserted in a frame; the lower ends of the bars dipped into a sand bath heated nearly to redness, while the upper ends were kept cold by a current of cold water. This kind of battery was specially claimed, in- dependently of the solutions, " for the purpose of generating electrical currents applicable to the deposition of metals." Messrs. Elkington appreciated the ingenious efforts of the inventor, and paid him for his invention the sum of £1600, less £110, the cost of the patent. He spent a con- siderable time at their works, experimenting on his process, and one of their present assistants remembers well the interest attaching at the time to the operations of the "young German," German," as he was called. His process is said to have been quite successful but owing to various changes which took place in the modes of manufacture, it was not : 48 [CHAP. IV. FIRST YEARS IN ENGLAND. commercially used to any large extent; being superseded by others more economical. Messrs. Elkington were, how- ever, well satisfied with their bargain; they were pleased with the young man and his ways, and remained always his powerful friends and supporters. The success of this enterprise transcended the most sanguine expectations of the family, and when young Siemens returned to Germany, he was considered quite a hero. Frau Himly wrote to Werner on July 7th, 1843, as follows:- A few days ago we had the first news from our dear Goldfish, since he has seen you. Your satisfaction at his appearance as Cræsus will naturally be as great as my own; it has been one of the greatest joys I have known. Ah! Werner! why have our dear parents not lived to see it! Shall you divide the money in´a fraternal way? I am convinced that William will make further fortunate speculations, and therefore you may, take your share without hesitation. In a letter to William himself, she said :— We all send greetings and good wishes to our Golden Brother. We have not yet heard you are engaged to be married; rich men like you are much exposed to that sort of thing: the girls will look on you with quite different eyes now! My husband asks whether any ebb-tide has yet begun in your treasure bag! We may make good allowance for family pride, as well as for the exceptionally favourable reception he received from Elkingtons, and still we cannot but admire the qualities shown by William on this his first essay in the real business of life. A young man of only twenty years of age, with scarcely any experience in commercial matters, almost without money or friends, and with only a limited technical knowledge of the matters he had to deal with, CHAP. IV.] LEAVES MAGDEBURG FINALLY. 49 had undertaken to negotiate, in a foreign land, even the language of which was strange to him, the sale of a new invention; and by dint of perseverance, intelligence, and skill, he contrived to effect the object of his mission with a success far beyond the expectations of those who had sent hitn. Such a beginning, although, as will be seen, it was followed by temporary reverses, indicated strongly the possession of those mental faculties and powers which ultimately determined his high position and character. The success was for the time eminently useful. The two brothers were becoming hard pressed by the charge they had taken of the younger children of the family, and the proceeds of William's business transaction came oppor- tunely to their relief in this pious duty. William returned to his situation in the Stollberg factory at Magdeburg, where he remained for the rest of the year. But the comparative ease with which the Elkington money had been obtained stimulated the brothers to bring out new inventions, and the correspondence between them in regard thereto was continued with much zeal. By a letter from Werner in Berlin to William at Magde- burg, dated the 28th of November, 1843, it appears that a third person, a clever mechanic named Leonhard, had been taken into their confidence. The "Chronometric Governor," mentioned in the last chapter, had been the chief object of study, and it was arranged that William should make a second journey to England and endeavour to sell it, the proceeds to be divided equally among the three. Some months passed in further discussion of the matter; the invention was patented in Germany; trials were made of it on a small scale, and the results of these being considered satisfactory, William finally left Magde- burg at the beginning of 1844. E 50 [CHAP. IV. FIRST YEARS IN ENGLAND. The following certificate was given him on leaving :- William Siemens of Menzendorf has been, and has worked as a pupil in this machine factory for about two years. During this time he has been industrious, trustworthy, and well-behaved. In addition to some manual work, he has especially been occupied in machine-drawing, and has acquired considerable facility therein. 19th January, 1844. SCHÖTTLER, Count Stollberg's Machine Factory, Magdeburg. He at once proceeded to London, where he arrived on the 8th of February. This visit determined his future career, for his efforts to introduce the new invention brought him in contact with the leading engineers and scientific men, and he received so much encouragement from them, that he was led to believe that a more congenial and more profitable field for his labour would be found in England than in his native country, and from that time England became his home. The invention of the Governor was the chief subject of his journey, but it was not the only one. The brothers had, among their multifarious schemes, taken an interest in a peculiar process of printing invented shortly before in Germany, and had together made some important improve- ments therein. It was therefore arranged that William should endeavour also to prosecute this invention, in con- junction with the Governor. The two occupied his earnest attention for some years, and it will be convenient now to trace his proceedings in regard to each separately. CHAP. IV.] THE CHRONOMETRIC GOVERNOR. 51 THE CHRONOMETRIC GOVERNOR. Mr. Siemens appears to have lost no time, for there is extant a brief manuscript notice of the general nature of this machine, written in imperfect English (although quite explicit and intelligible) the day after his arrival in London, the 9th of February, 1844, and signed "Wilh. Siemens, Civil-Ingeneer of Berlin." Armed with this document he waited on the Consul- General for Prussia, Mr. Bernard Hebeler, who not only received him kindly but was afterwards an earnest and useful friend to him. Mr. Hebeler pointed out the necessity of his associating himself with some one who could aid him in the technical part of his work, and for this purpose in- troduced him to Mr. Joseph Woods, a civil engineer of repute then practising in London. Mr. Siemens quickly appreciated the advantage of such an association, and after due discussion of his objects and plans, an arrangement was made between him and Mr. Woods for joint action. The first step necessary was to secure the invention by an English Patent, and this was taken out in the name of Mr. Woods on the 18th of April, 1844. It may be conve- nient here to give a brief description of what the invention was. Steam engines for turning machinery have always been liable to irregularities in their velocity of motion, arising partly from variations in the steam-pressure, and partly from variable resistances in the work done. Several con- trivances have been used or tried to equalise the motion› but the one most successful has been the well-known governor❞ invented by Watt, consisting of a centrifugal pendulum caused to revolve with the engine, and connected with the throttle-valve admitting the steam. When the E 2 52 [CHAP. IV FIRST YEARS IN ENGLAND. movement is accelerated the pendulum rises and diminishes the steam-pressure; when, on the other hand, the movement is retarded the pendulum falls, and by enlarging the steam passage tends to produce acceleration. It was well known to engineers that this contrivance, though fairly efficient for ordinary purposes, was not a perfect regulator, as its action admitted necessarily of cer- tain fluctuations in the speed; and as the brothers Siemens conceived that greater uniformity would be desirable, they tried to improve the mode of regulation. They conceived the ingenious idea of establishing, alongside the engine- shaft, another independent rotating movement, the speed of which should be invariable, and should serve to regulate the velocity of the engine. This second movement was actuated by a weight, and the uniformity of its rotation was easily secured (as it was subject to no variations of power or load) by simple regulating contrivances. The comparison between the uniform and the variable motion was made, by a very ingenious device, not only to declare itself automatically, but also to effect the regula- tion. The main engine-shaft turned an endless screw which geared into a pinion connected with the uniform motor, and was also capable of sliding longitudinally in the direction of its axis. When the two velocities corre- sponded, the screw revolved without any sliding, but the moment the engine velocity began to vary, the screw began its longitudinal motion, and by a connexion with the steam-admission this effected a regulation of the most efficient and sensitive character. An improvement, pa- tented by Mr. Siemens in 1845, substituted a bevel-wheel arrangement for the screw and pinion, and further improve- ments of a minor kind were included in a patent of 22nd December, 1847. It will be seen that the novel feature of the invention, CHAP. IV.] THE CHRONOMETRIC GOVERNOR. 53 C namely, the added uniform motor, acted as a time-keeper, with which the motion of the engine could be compared, and this gave to the invention the name of the "Chronometric Governor." Mr. Siemens, presuming on his fortunate experience with the electro-plating inventions, at first wished to sell the patent-right entirely, which he valued at an enormous sum, namely about £36,000. But he soon found that such a transaction was out of the question, and he consequently endeavoured, in conjunction with Mr. Woods, to adopt some other means of making the invention productive. It was proposed to grant licenses; but even this did not answer, and it became necessary, in order to induce manu- facturers to try the machines, that Messrs. Siemens and Woods should actually supply them, getting them made under their own direction. In order to bring the matter more prominently under the notice of the engineering world, Mr. Woods, on the 10th of March, 1846, presented a Paper on the subject to the Insti- tution of Civil Engineers, giving a full description of the machine, and explaining its advantages. The invention was very favourably received, and in the discussion that followed the Paper, several eminent engineers, including Mr. Robert Stephenson, Mr. Charles May, and Mr. Joshua Field, gave testimony in its favour. Some months later Mr. John Penn (one of the best authorities in such a matter) expressed himself as follows in a letter to Mr. Hebeler, September 1, 1846 :— I have and always have had a very favourable opinion of Siemens's governor, and think it reflects much credit on the in- I hope to see it extensively applied, and have no doubt it will be, when more generally known. ventor. With these advantages the invention had a good start, and the governors were applied to many steam engines 54 [CHAP. IV. FIRST YEARS IN ENGLAND. in various parts of the country, occasionally in the works of eminent engineering manufacturers. Some of them appear to have effected their object, and to have been reported on favourably; but, as in the case of many mechanical novelties, a good deal of trouble and difficulty was occasionally met with in their application, and cases of failure were not uncommon. The manufacture was per- severed in for many years, and it will be found alluded to in future periods of this biography. A working model of the governor was exhibited at the Society of Arts in 1849, and again at the Great Inter- national Exhibition in Hyde Park in 1851; it was spoken of in the Jury Report of the latter as "well known and approved," and was awarded a "Prize Medal." ANASTATIC PRINTING. The other invention which William Siemens brought to England in 1844 created considerable sensation at the time, and its early history is curious. In October, 1841, the proprietors of the Athenæum journal received, from a correspondent at Berlin, a reprint of four pages of their number of 25 September, containing some woodcut illustrations. The copy, both of the letter- press and of the engravings, was so perfect a facsimile, that if it had reached them under other circumstances they would never have suspected that it had not issued from their own office. They urgently applied for explanation, but all they could learn was that this, and similar reprints of other illustrated works, had been made by a new process lately discovered, which was kept a profound secret. The Athenæum published a notice of this on December 4, 1841, headed "Printing and Piracy," and pointed out the vast evil which the discovery might inflict on the publishing CHAP. IV.] 55 ANASTATIC PRINTING. trade, particularly in regard to costly illustrated works, the reproduction of which had been hitherto supposed too difficult to be attempted by unauthorized hands. They sent the copy they had received to the Government, and it was submitted by Lord Monteagle to the Commissioners appointed to inquire into the Exchequer Bill forgeries; but no further notice appears to have been taken of it. In the meantime the process was being further tested in Germany. The inventor of it was a Mr. Baldamus, who originally lived at Erfurt, but who afterwards removed to Berlin. During his efforts to perfect the invention, he became acquainted with the brothers Werner and William Siemens, to whom he explained his process; and they, seeing its merit and probable advantages, agreed to join him in it. William especially contributed his mechanical skill to its improvement by designing presses adapted to it, one of these being, moreover, the first roller quick printing press that had been used in the trade. When William made his arrangement with Mr. Joseph Woods, this process was included in the bargain, and Mr. Woods took out an English patent for it on June 6, 1844. It was entitled "Improvements in producing and multi- plying copies of designs and impressions of printed or written surfaces;" and the patent embraced two objects. First, a mode of obtaining, on metallic surfaces, reversed facsimiles of typography, engravings, designs, writings, &c. and secondly, mechanical presses for printing impressions from such reversed facsimiles. ; The process generally was called "Anastatic Printing," being the avάoτaois, or fresh raising up, of copies.* * This very appropriate name was suggested by Mr. Joseph Woods's brother, Mr. Edward Woods, lately President of the Institution of Civil Engineers. 56 [CHAP. IV FIRST YEARS IN ENGLAND. The readiness with which part of the ink of any newly printed book, or engraving, can be transferred by pressure to a smooth surface beneath, is well known, and this was taken advantage of to obtain a reversed facsimile on a plate of zinc. When the ink was old, the transfer was facilitated by certain chemical means. The plate was then treated alternately by water and by oily ink, as in lithography, and from this, by proper presses, the required copies were obtained. The presses were of two kinds; either small presses worked by hand, or larger self-acting machines moved by steam power. Specimens of the printing were laid before the Society of Arts on the 27th November, 1844, and the process was noticed again in the Athenæum of 18th and 25th January, 1845, exciting much admiration, mixed as before with some alarm at its possible results. A month or two later it was exhibited to the President and many influential members of the Royal Society, and it attracted the attention of Professor Faraday, who thought it of sufficient importance to devote to it a Friday- evening lecture at the Royal Institution. This was delivered on the 25th April; * the lecturer explained the process in his usual clear manner, and during the description a complete anastatic copy of a page of a printed work, with woodcuts, was made by Mr. Woods, who attended for the purpose with his press and workmen. Mr. Siemens stated, in later life, that this favourable notice had obtained for him an entry into scientific circles, and helped to sustain him in the difficulties which soon after he had to encounter. * An abstract of the lecture will be found in the Athenæum of 3 May, 1845, page 437. CHAP. IV.] 57 ANASTATIC PRINTING. C Mr. Siernens was at first as sanguine about this invention as about the governor, and he valued the patent right at the high figure of £50,000. But here again no purchaser could be found, and it was resolved that Mr. Siemens and Mr. Woods should together introduce the invention to the public, and try to render it profitable by actual working. Much depended on the presses, and it was necessary in the first place to experiment on and perfect them, par- ticularly the self-acting steam press, which was expected to be the most important element of success. They were put into the hands of two eminent mechanical engineering firms, Messrs. Easton and Amos, of Southwark, and Messrs. Ransomes and May, of Ipswich, and much care was bestowed upon them. When they had been sufficiently tested, it was considered advisable to found what was called a "Grand Printing Establishment," where the anastatic process could be commercially worked for the public demand. Workmen had to be specially trained, and a connection opened among various branches of trade connected with literature and art, all which took a long time, involved the outlay of large sums of money, and was attended with much trouble and anxiety. These proceedings lasted for some years. It is difficult now to trace exactly the various phases of the concern; sometimes we find mention of favourable results, but the chief records are those of difficulty and disappointment, which at length drove Mr. Siemens to abandon the thing altogether. He had been assisted throughout the work by a Mr. Appel, a German who had been originally a workman of Mr. Baldamus, and on the 30th December, 1846, Mr. Siemens wrote to him as follows:- DEAR APPEL,—I am sorry to be obliged to inform you that our outlay for the object of bringing the printing to practical perfection 58 [CHAP. IV. FIRST YEARS IN ENGLAND. has so largely increased, and that there is at present so little pro- spect of its becoming profitable, that we find ourselves compelled next year to give it up altogether. The orders taken must however be carried out, and I will ask you to get a perfect set of samples of all kinds for use hereafter. I have arranged with Mr. Woods that the premises shall be closed on the 15th of January. Mr. Siemens then suggested in some detail what it might be advisable for Mr. Appel to do, and offered to help him in every possible way. The result of this was that Mr. Appel carried on the process on his own account for some years with varying success, showing it at the International Exhibition of 1851. It was, however, ulti- mately superseded by other processes, and it does not seem to have ever realised, commercially, the anticipations of its inventors and promoters. [DIFFICULTIES AND TRoubles. The first three years of William's residence in England were chiefly occupied in trying to introduce the two inven- tions above described; and they were memorable years to him and his family on account of the disappointments and troubles which the attempt involved him in. His first brilliant success had made him unduly sanguine, as is shown by the preposterous money value he attached to the new inventions. And even though he failed to find purchasers, he seems to have still expected that his attempt to work them himself would be easy, and largely remunera- tive. But he had the inexperience as well as the confidence of youth, and he was doomed to see his anticipations bitterly disappointed. In the first place, it was necessary to find money, and to spend it with no sparing hand. He himself began the out- CHAP. IV.] 59 DIFFICULTIES AND TROUBLES. lay; he was entitled to a small patrimony of about £700; this was realized, and, together with all his ready money, was appropriated very soon. Then his brother Werner, and his sister Frau Himly, who both shared in his expecta- tions, shared also in the expenditure. Then Mr. Woods advanced a considerable sum, and when all this had been swallowed up, still larger contributions were obtained, chiefly through Mr. Hebeler. In a letter to this gentleman, dated 12th December, 1844, we find Mr. Siemens thanking him warmly for former help, and assuring him of the pro- spect of success, but expressing his regret at the heavy expenditure, and asking for further advances. It was not only for working the two inventions in England that money was wanted, but such was the con- fidence of the brothers in them, that patents were taken out in France, Belgium, Prussia, Austria, Bavaria, and most of the German States, all which required heavy payments, with very remote probabilities of return. And the items of expenditure were sometimes of a curious character, for in one letter William speaks of the governors requiring to be "well-greased" (i.e., the men using them wanting heavy fees) to make them work well. Moreover the prolific ingenuity of the brothers was con- tinually prompting them to new inventions. We find them discussing schemes for improvements in paper-making, ships with new modes of propulsion, winged rockets and flying apparatus, locomotives on new principles, railway appliances, and in fact a long miscellaneous category of contrivances, all to be patented and experimented on, if money could be got for the purpose. In some of these cases William's ingenuity ran ahead, and the elder brother had to restrain him. In one case Werner said, “Parental love is a beautiful thing, but it makes the sharpest eyes blind to the defects of the progeny." On 60 FIRST YEARS IN ENGLAND. [CHAP. IV. the other hand, we occasionally find William exhibiting a "Furcht" about the schemes which Werner had en- couraged. But they did not confine their attention to their own inventions; they interested themselves also in those of other people. Werner said in one of his letters :- We have already obtained fame, people are continually applying to me, directly or indirectly, to introduce their inventions, and we might do a good business in this line. And of course" introducing the inventions" usually implied finding money for them. Among other things, William entered into negotiations in 1845 with Mr. Frederick Ransome of Ipswich (at whose house he was a guest while the Anastatic Press work was going on) in regard to a process Mr. Ransome had in- vented and patented for the manufacture of artificial stone. William devoted much time to the examination of the process in this country, while Werner actively endeavoured to introduce it on the Continent. The process is well known as a successful and valuable one, but it does not appear that the efforts of the Messrs. Siemens led to any result profitable to them. But the inventions pressed upon them were seldom of such a good character. In one case we find an application. from a Mecklenburg sculptor, who, having, as he believed, discovered the "perpetual motion," wrote to William urging him to claim for it a large prize, which he under- stood had been offered in England for the discovery, the application being accompanied by formal certificates from the civic authorities, testifying to the perfect success of the machine! When it was found that all the money was disappearing CHAP. IV.] 61 DIFFICULTIES AND TROUBLES. without any immediate prospect of return, some of the parties who had advanced it naturally became uneasy. At first there had been full confidence. One of William's friends in Berlin wrote, for example, "I shall hope to see you here soon, when you have again got some thousands of pounds sterling out of the goddams!" And we often find mention of "attractive hopes," "high return for ad- vances," and so on. But these sanguine expectations were soon seen to be delusive. Even early in 1844 Werner began to complain of the unsatisfactory notices sent home by his brother, and in writing of his sister said, "Mathilde complains bitterly and loudly over our speculation, which she considers already totally lost." As time went on such complaints continued to increase; for Werner had heavy expenses of his own to meet, and he felt keenly the continual drain which the inventions caused, keeping him, as he expressed it, in a continual state of “money famine." Even the workmen employed had to suffer, for instead of receiving payment to provide them with necessaries, they had to be put off with promises of a share in the ultimate gains. But the money loss was not the worst of the matter, for the disappointments and failures that occurred gave rise to complaints, dissensions, and recriminations among the parties concerned, which, had it not been for good temper and forbearance on all sides, would have caused irreparable mischief. William Siemens found himself in a very delicate position. He had to earn his living, and it was not agreeable to him to appropriate to this purpose the money advanced by his relations and friends. He might easily have found less anxious means of obtaining a livelihood (and indeed a proposal was once entertained of his going back to manage C 62 [CHAP. IV. FIRST YEARS IN ENGLAND. a manufactory in Germany), but he was restrained by the conscientious scruple that, having induced his friends to lend their money on the faith of his assurances, he was in honour bound to stick by them, and do his best for their interests. A few extracts from some of his letters during this time will illustrate his state of mind. On the 31st of May, 1845, he said :- • I could not look any longer cool while my affairs get injured and spoiled daily more and more. At present I am almost ashamed to say I am connected with the Anastatic Printing . The whole proceeding stops and suffers, while I am condemned to be a silent spectator, to see the injury which is done to my own and confided property, and the gradual decay and ruin of my future happiness. . . I only ask for so much more as to enable me to pay my immediate debts, having not been able to satisfy my land- lady for some time. On the 18th of October he further wrote :— There must be made some great alteration in the mode of carrying on our business; for one thing, this being the date of the glorious day of Leipsic, I will, in remembrance of it, gain one victory over myself, which is, that I will not indulge any more in quarrelling I am now determined to discontinue this tantalizing idle sort of life, and to take a situation, however humble, whereby I can secure the means to provide for myself . . . Finally, I offer you my hand, to drop all feeling of animosity, which has made me sick already. • In the autumn of 1845, being desirous to earn something independently of the patent business, he undertook some railway work. It cannot now be ascertained what or where this was, or who put it in his way; but as that was the time of the great railway mania, when the services of engineers were so much in demand, he had probably not to look far for such employment. At any rate, he was CHAP. IV.] 63 DIFFICULTIES AND TROUBLES fortunate enough to get paid for it, and the money thus earned enabled him to go to Germany, and settle some private affairs. By the end of that year things had become so much. worse that the two brothers came simultaneously to the conclusion that the attempt to work the inventions must be abandoned. William's first step, in furtherance of this view, was to relieve his brother from all further responsi- bility, taking the duties that remained entirely on his own shoulders. The letter from him to Werner, conveying this resolution, is unfortunately lost, but its general nature may be inferred from the following passages in Werner's answer, dated the 3rd of January, 1846. Our joy over your letter, which we received on New Year's Eve, and especially my own satisfaction at the agreement of our views, prompted us at once to go to see poor Meyer, and drink a glass of grog with him to drown the disappointed hopes of the last year. But the gloomy feelings were alieviated by the new course of life which is now marked out for me. I have given up all my former sanguine expectations, and will, in accordance with your advice, now devote all my energies to one object, namely, to the galvanic telegraph, and what hangs thereupon. I will use every effort to extricate myself from the desperate position in which I have been placed, and I wish myself health and perseverance to attain my object. I am glad that you have come to a similar resolution; take care that you succeed in it. Make use of any of our hitherto joint affairs which you may think desirable, and throw the rest away. I hereby renounce all claim on any success that you may hereafter bring about, in regard to them. We shall still remain true brothers, and may still reciprocally help one another. If can aid me in finishing the heavy task I have already begun in the education of our brothers, you will, I know, do so, and I shall receive your help with much pleasure. It is both your right and your duty to share this care with me. you But do not suppose that I write this in any momentary excite- C 64 [CHAP. IV. FIRST YEARS IN ENGLAND. ment, and that I may repent it afterwards. The resolution has been long in my mind, and I have only been waiting for an oppor- tunity of expressing it to you. Do not therefore raise any objec- tions, which will be useless. We have many other things to confer on together. The governor affair lies dead; I am glad to get rid of it, and will not worry myself about it any further. I will sell the three specimens I have cheaply. I and the brothers heartily wish you, if not a joyful, at least a fortunate and profitable new year. May our paths, from hence- forth separate, bring each of us to the goal we are striving for. Good luck to us! William could not himself immediately give up the patent business. He was obliged to do what he could to extricate himself honourably from his engagements, and he still believed at least in the Governor. When, therefore, he had relieved Werner of his troubles in regard to it, he made an engagement with a firm in Hamburg to act as continental agents for that invention. In May, 1846, he had an offer, from the Government of Peru, of employment in that country, but he did not con- sider the state of things there sufficiently stable to justify him in accepting it. On the 19th of June we find him writing a long letter to his London colleague, containing the following passages:- You took a part in these two inventions, which I wish, with all my heart, had never come to my knowledge. So long as my own property lasted I entertained no doubt that the patents would be sold for the price which they were worth at the time, before my means were exhausted. I was, however, disappointed . . . I had to labour under the greatest disadvantages, and was con- stantly exposed to the meanest chicanery. . . When I came back from Germany I found the printing establishment much neglected, being left under the charge of a decayed schoolmaster. I tried to improve it, but he gave it its death-blow by a measure so utterly absurd that I did not feel justified to sacrifice any more time about • CHAP. IV.] 65 DIFFICULTIES AND TROUBLES. it. . . In addition to all this which I had to encounter, I had sometimes not the means of living, my small paternal heritage and all other property being entirely consumed. Thus I have passed two and a half years in perfect secludedness and painful anxiety, devoting the best strength of my life entirely to these two inventions, the fate of which I have not even the power to con- trol. . . . The advance of money binds me in honour to persist in our mutual cause, without seeing any chance of their proving beneficial to me. I have already been obliged to reject two • offers which would have secured me a comfortable living. How I can, under these circumstances, prove my energy I am at a loss to understand. I wish for work, and plenty of employment is the only thing that makes me feel happy. Discussions of this kind went on till the end of the year, when he succeeded in bringing the whole affair to an end. Lamentable, however, as all this was while it lasted, there is no doubt that it served a useful purpose, by educating and training Mr. Siemens for his future career. Notwithstanding his great ingenuity, he was as yet wanting in practical experience of the technical difficulties which beset new mechanical inventions, and he was still more ignorant of the multifarious obstacles which stand in the way of their commercial success. The idea that an invention which appears promising to the inventor ought at once to find a remunerative application, is a delusion which too often exists in young and sanguine minds, and which is only to be eradicated by bitter experience. These years served to purge young Siemens's mind of many such fallacies; he not only acquired in them a much larger and more useful technical experience (for it is an axiom in engineering that failures are the best teachers), but they made him better acquainted with the commercial views of inventive industry, and these advantages amply compen- sated him in future life for the troubles he had undergone. F 66 [CHAP. IV. FIRST YEARS IN ENGLAND. AIR PUMPS. During this period Mr. Siemens brought out another invention, which, although it did not yield him any profit, is worth mentioning. It was an improvement in the manner of exhausting air by mechanical power. His attention was drawn, in 1845, to the atmospheric railway system, which was at that time exciting considerable interest, and on the 10th of March in that year he wrote to Mr. Charles May (an eminent engineer who had occupied himself in that matter), proposing an improvement in the mode of exhausting the air from the atmospheric tube. Nothing came of this at the time, but about a year later the suggestion was renewed. The invention was examined and thought well of by Mr. (afterwards Sir William) Cubitt, Mr. Brunel, and Mr. Samuda, the promoters of the line, and it was determined to make a trial of the plan, when the action of the railway became deranged, and the system was abandoned. Mr. Siemens, however, included the invention in the specification of his second Governor Patent of the 24th December, 1845. The chief part was briefly described by him in the claim as "a Double Cylinder Air-Pump for compressing or exhausting elastic fluids generally, thereby diffusing their resistance more equally over the up and down stroke of the pistons." The two cylinders were of unequal capacities, and were so arranged that the com- pressing side of the first or larger cylinder communicated with the suction side of the second or smaller one, whereby the limit of exhaustion was much extended. The plan was afterwards used with success, particularly for exhaustion in sugar-boiling. CHAP. IV.] THE REGENERATIVE STEAM-ENGINE. 67 HEAT AND ITS APPLICATIONS. The Regenerative Steam-Engine. Being wearied with the troubles of the governor and the printing patents, Mr. Siemens determined to strike out a new line of action. During the year 1846 he had occasion to visit the manu- facturing districts of Lancashire, and, seeing a prospect of profitable employment there, in the early part of 1847 he removed to Manchester, where we find him addressed, first at No. 4, Town Hall Buildings, and subsequently at II, Talavera Place, Broughton, and 50, Burlington Street, Green Hays. He appears to have been engaged on several engineering matters for different parties, but his principal source of income was derived from an engagement at the large print works of Messrs. Hoyle and Sons, Mayfield. Following up the ideas he had carried out at Messrs. Elkington's, he had entertained a plan for the electric coating of metals, not, as before, for the sake of appearance, but by a thicker and more substantial deposit, which should be serviceable in the arts; and he further proposed, in connexion with this, to make more extended use of the electrolytical process as a mode of copying engraved designs. At the Mayfield Print Works, among other things, he made extensive experiments with the view of improving, by these means, the modes of obtaining the engraved copper rollers. used in calico printing. But the most important result of his residence in the Lancashire district was the attention he paid to the nature of steam-power. This was the foundation of the whole industry of the country; steam-power depended on the F 2 68 [CHAP. IV. FIRST YEARS IN ENGLAND, application of heat; and his keen observation soon showed him that this element was but imperfectly understood, and might probably offer a fertile field for his inventive powers. His anticipations proved correct, for it may be said that heat became thenceforward the chief object of his study. He employed himself upon it, in some form or other, throughout the whole of his subsequent life, and his later labours in regard to it assumed a magnitude beyond any other of his occupations. He had studied the theory of heat, and had kept pace with all the later discoveries therein. He had made himself master of the profound investigations of Joule, Mayer, Carnot, and others, and had become well acquainted with the great modern doctrine of the Conservation of Energy, of which the dynamic theories of heat had furnished such conclusive demonstration. Applying to these theoretical considerations his eminently practical mind, he could not fail to see what an enormous loss of valuable energy was continually going on, by the waste of heat, in almost all manufacturing and industrial processes, and it became his earnest endeavour to discover and introduce means of saving this wasted power. He had already, towards the end of 1846, been discussing with his brother Werner the action of heat as a power- giving element, and he was prepared to take any oppor- tunity that offered for continuing his investigations in a practical shape. His first efforts were naturally directed to the steam- engine, for it had been one of the first corollaries from the thermo-dynamic theory that this machine, in its most perfected state, only utilized a small fraction of the energy developed by its combustion of coal. CHAP. IV.] THE REGENERATIVE STEAM-ENGINE. 69 In the spring of 1847, being engaged at the works of Mr. John Graham, of Manchester, he had occasion to undertake some operations with the condensing apparatus of the engine, and turning over in his mind the subject of the loss of heat, he conceived the idea of an arrange- ment which he thought would save some portions of this waste. After a full discussion of the invention with his brother, he consulted, confidentially, Mr. John Hick, an eminent mechanical engineer of Bolton, on the matter; and Mr. Hick, after making some experiments, gave his opinion that though there would be many practical difficulties in applying the invention, yet the principle was good and promising, and it deserved a trial. He further liberally agreed to construct, under Mr. Siemens's direction, an experimental engine, in order to test the practicability of the scheme. This engine was ready towards the end of the year; it was of four horse-power, and its results were so far suc- cessful as to encourage Mr. Siemens to proceed with the patent, which was accordingly granted on the 22nd of December, 1847, under the title of "Improvements in Engines to be worked by Steam and other Fluids." In addition to the engine built by Mr. Hick, he had engaged with Messrs. Hoyle to construct for them an experimental condenser and a drying apparatus, both embodying applications of the new principle, and by the aid of these constructions he occupied himself in working out and improving the details of his plan for a great part of the year 1848. The designs being matured, Mr. Siemens sought for help in carrying out his invention, and Mr. Woods intro- duced him to a manufacturing firm of great eminence and large capabilities, Messrs. Fox, Henderson, and Co., of 70 [CHAP. IV. FIRST YEARS IN ENGLAND. Smethwick, near Birmingham. Some negotiations took place, and their nature may be inferred from the following draft letter found among Mr. Siemens's papers :- 3, BARGE YARD CHAMBERS, BUCKLERSBURY, 20th June, 1848. Messrs. CHARLES Fox and JOHN Henderson, GENTLEMEN,—In reference to our conversation respect- ing my patent for "Improvements in Engines to be worked by Steam and other Fluids," sealed on the 22nd of December, 1847, I beg to inform you that I desire your assistance by entering fully into the manufacture of these engines, and taking on yourselves the expenses contingent thereon, excepting so far as regards the outlay incurred by Mr. Hick, of Bolton, in consideration of which he is entitled to receive 1 sterling per horse-power of 70,000 lbs. raised 1 foot high per minute, as shown by indicator. It is my desire and intention that you should have the exclusive working of the patent, in such manner as may hereafter prove most advantageous to all interested therein; and in order to induce you to use your best endeavours to introduce these im- provements, I am willing to sell you one-third share in the pro- perty of the said patents for England and Scotland for the sum of £1000 sterling, to be paid as follows: £500 within one month from the date hereof, and the remainder by a bill at six months date from the payment of the first instalment. I hereby acknowledge a first payment of £100 on account of the first instalment, for which I give you my acceptance secured on the patent until our final agreement is completed, in order that you may have the said £ico returned if our final agreement should by any event fail. CO I am, yours truly, C. W. SIEMENS. This draft appears to have been written by Mr. Joseph Woods, who always acted as Mr. Siemens's adviser, until his sudden death by cholera in the fearful epidemic of that disease which prevailed in London in the autumn of 1849. His loss was a real calamity to Mr. Siemens, as, notwith- CHAP. IV.] THE REGENERATIVE STEAM-ENGINE. 71 standing occasional differences, Mr. Woods had been always one of his best friends. The negotiation with Messrs. Fox and Henderson does not appear to have led, at that time, to any definite arrange- ment, nor indeed does Mr. Siemens seem then to have been very sanguine as to the success of his invention; for on a visit to his sister at Kiel in the beginning of 1849, an idea was seriously put forward by him that he, with his brothers Frederick and Carl, should go over to the gold diggings in California, which were then attracting multi- tudes of enterprising spirits. This proposal was, as usual, discussed in the correspondence between the brothers, and a few characteristic remarks by Werner upon it, in letters ranging between January and March, may be extracted. He said:- เ Your earnest wish to go on adventures in a far land is intelli- gible to me. I should have it in your place, and indeed have had it. I am not inclined to warn you, or even to express a wish against it; it would grieve me to see you take a step which might part us for ever, but I should rejoice as much to see you make your fortune there as here. Then it is clear America is rising; we are sinking; and an in- dustrious and well-educated man will there always fall on his feet. So if you, Fritz and Carl, are adventurous and resolve to go, I will offer no impediment, but will give you every help I can. I believe, however, that it is better to make gold than to seek it ; the value of hand-labour must be equilibrated, and since gold- seeking has become a mania, this labour must be the worst pro- vided for. Brewing, distilling, tool-making, and so on, will be the best means for seeking gold. The idea was abandoned, and the negotiations with Messrs. Fox and Henderson were resumed. At the end of November, Mr. Fox, accompanied by his chief engineering manager, Mr. Edward Cowper, went to Mr. Hick's factory at Bolton, to see the new engine, which was shown and 72 [CHAP. IV. FIRST YEARS IN ENGLAND. explained by Mr. Siemens. Its working was not very satisfactory, but after some further consideration the firm agreed to take the matter in hand. It was, however, thought desirable that Mr. Siemens should be on the spot to give his personal services, and an arrangement was made for him to attend in Messrs. Fox and Henderson's manufactory, receiving, not only his interest in the patents, but also a fixed salary of £400 a year, which relieved him from anxiety as to his means of livelihood. He accordingly removed to Birmingham, and entered on his work early in the year 1849, taking a lodging at Summerfield Cottage, Birmingham Heath, a mile or two from the factory where he was occupied. He had an office to himself, and was given the services of the chief drafts- man of the firm, to aid him in the designs. At a later date, his brother Frederick, who had come over from Berlin, was engaged by the same firm at a salary of £2 per week, to aid in the preparation of the drawings, and in other works connected with his inventions. This arrangement lasted some years, and was of much advantage to Mr. Siemens; it enabled him to carry out experiments serving as a preparation for the brilliant heat- applications of his after-life; and, what was of equal importance, his work and attentive observation in a factory renowned as one of the first schools of mechanical engineering in the country, gave him an amount of practical experience which was of the greatest benefit in his futuré career. He profited much by the advice and assistance of Mr. Cowper, who remained his firm friend through life, and gave him essential support in his later heat- inventions. It may here be advisable to give some brief description of the "Regenerative Steam-Engine." CHAP. IV.] THE REGENERATIVE STEAM-ENGINE. 73 The patent of 1847 shows that in Mr. Siemens's first attempt at heat-saving, he endeavoured to apply the eminently simple and practical idea which afterwards formed the leading feature of his great heat-inventions, namely, what was called the "regenerative principle.” He found that in almost all industrial applications of fuel, heat was lost by the passing away of currents at high temperatures; and it occurred to him that by presenting suitable masses of solid conducting matter to these currents, their superfluous heat might be taken up, and might then be given out again in some useful way. << The simplest illustration of this process may be found (though applied for a different purpose) in the ordinary respirator" used by consumptive persons. A pierced metallic plate is fixed over the mouth, and when the warm breath is exhaled, its heat is taken up by the metal, so that in the following inhalation, the cold air, passing in the reverse direction through the pierced plate, picks up again the heat stored therein, and so becomes warmed before entering the lungs. The application of this principle to the arts is easily understood. If any highly heated current, escaping from a heating operation, is made to pass through such a “respi- rator" before it reaches the atmosphere, it will deposit a certain amount of its heat in the metal; and if, then, a cold current from the atmosphere be sent through it in a reverse direction, it will pick up such heat again and become warmed, so saving fuel. This is the "Regenera- tive Principle." The name is not appropriate, as there is no regeneration of heat; it is only a temporary ab- sorption and a subsequent giving out again, as water may be temporarily absorbed by a sponge; but the term 74 [CHAP. IV. FIRST YEARS IN ENGLAND. has come into use for the purpose, and can hardly now be changed.* It is right to say that the principle in question was not claimed as an original discovery by Mr. Siemens. It had been clearly described in a patent taken out as early as 1816 by the Rev. Dr. Stirling, and had been applied both by him and by Captain Ericsson to heated-air engines; but it was looked upon by engineers as unsound in prin- ciple, and its application had very little beneficial result. Mr. Siemens saw not only its theoretical correctness, but its great practical value, and the wide success it afterwards attained fully justified his views. The patent showed two applications of this principle, namely, a "Regenerative Engine," and a "Regenerative Condenser." The first of these was a very elaborate machine. It followed, generally speaking, the principle of the previously existing heated-air engine, but with the substitution of superheated steam for air. The steam was used in a single-acting vertical cylinder, the lower part of which was heated by a furnace. After propelling the piston upwards, the steam was withdrawn from the cylinder and passed through a respirator, where it deposited a large portion of its heat, and became cooled and reduced in pressure, so allowing the working piston to descend. It * The erroneous name is due, however, not to Mr. Siemens but to Dr. Stirling, the inventor of the apparatus. In a letter to Mr. Manby, dated Oct. 1, 1853, Mr. Siemens said, "Have the kindness to assure Mr. Stirling that I have no desire to undervalue the merit of his brother and himself, which merit I consider is very great indeed, since I have learnt that they are the originators of the Respirator (or Regenerator). I shall be glad to profit by any further correction or suggestion which Mr. Stirling may wish to make; and perceiving him to repudiate the name ‘Respirator,' I really think he would confer a benefit on posterity if he would give his child a proper name, that of 'Regenerator' being certainly incorrect, and likely to produce misconception." CHAP. IV.] THE REGENERATIVE STEAM-ENGINE. 75 ر. was then forced back, picking up a portion of the heat again, and receiving a further increase of temperature from the fire, to cause it to repeat its working stroke as before. A small quantity of fresh steam at high pressure (but only about one-tenth of the contents of the cylinder) was admitted from a boiler at the beginning of every working stroke, and a corresponding quantity was allowed to escape in its expanded and cooled condition into the atmosphere or into a condenser. Two cylinders of this kind worked side by side, with alternating strokes, and acting on the same crank-shaft. The respiratory or "regenerative" process was at first performed in a series of successive chambers; but the action was afterwards simplified by the substitution of a regenerative cylinder and piston, and respiratory surfaces more nearly resembling the original simple type of the apparatus. Another important feature of Mr. Siemens's patent was what he called his "Regenerative Condenser," which he afterwards further improved by a modification patented on the 20th of March, 1849. In order to get a good exhaus- tion, it was desirable to keep the condenser cold, while to feed the boiler it was advantageous that the water coming from the condenser should be as hot as possible. He contrived to make the regenerative principle satisfy these antagonistic requirements in an ingenious way. He made the exhaust steam first pass through a metallic respirator, so depositing a large portion of its heat; after which it entered the condenser proper, which was kept cold, and in which accordingly exhaustion was obtained. The water collected in the condenser was then forced back through the respirator, so picking up the heat again from the metallic surfaces and arriving at the "hot well" in a highly 76 [CHAP. IV. FIRST YEARS IN ENGLAND. heated state, to be fed into the boiler. The advantages he expected to obtain were chiefly increased power from the better exhaustion, and the saving of heat by using boiling feed-water. The manufacture of the engine was duly taken in hand at Fox and Henderson's works according to the agreement, but it progressed very slowly. A condenser, designed according to the improved plan of 1849, was made in September of that year, and attached to a 16-horse-power engine at Saltley Works near Birmingham. It was not perfect, but it served to illustrate the principle. On the strength of this, Mr. Siemens, in May, 1850, gave a description of the condenser to the Society of Arts, ex- plaining its principle, and stating the result of its working. Mr. Robert Stephenson was in the chair, and after the reading of the paper a considerable discussion arose, in which the Chairman, Mr. Scott Russell, Mr. Crampton, and others took part, the general opinion being in praise of the novelty and ingenuity of the invention. The result was that the Society awarded Mr. Siemens, for it, their gold medal, which was presented to him on the 22nd of July in that year. In 1851 he wrote another paper for the Institution of Mechanical Engineers, entitled, "On a new Regenerative Condenser for High and Low Pressure Steam Engines." It was read at the meeting of the Institution at Birmingham, on the 30th July, 1851. The author gave a short historic sketch of the steam-engine condenser generally, explain- ing his new arrangement, and its mode of application to different forms of engine. About the same time, one of the complete Regenerative Engines, of 100-horse power, was put in hand, but it was a long time under construction, and the experiments made CHAP. IV.] 77 REGENERATIVE EVAPORATION. with it were not satisfactory. On the 26th of March, 1851, Werner wrote- Your delay in announcing the success of your engine troubles me; I believe you will have found many defects which must be remedied. But hold up your head if the first attempts fail; you have strength enough to build success upon them. こ ​On June 2nd the prospect seemed brighter, although Werner still advised patience— Quantitative determinations are necessary to prove the value of the thing, and longer experiments will in any case lead to many modifications. Rome was not built in a day! Werner was right; for at the end of 1851, the results obtained by the engine were so doubtful, that it was de- cided to construct a new one on altered plans. Regenerative Evaporation. During Mr. Siemens's work on his engine, it occurred to him that the regenerative principle might be applicable with advantage to other purposes where heat was em- ployed, and among them to the process of evaporating liquids on a large scale, as in the manufacture of salt and sugar, and in distilling operations. Towards the end of 1848, he entered into communication with some large salt manufacturers on the subject; he did not get much en- couragement from them, but he included the apparatus in his patent of 1849. He called it a "Regenerative Evaporator." It was a most elaborate arrangement of evaporating pans, but its general nature may be expressed by the following quota- tion from the patent specification: The improvement in the process of evaporating brine or other liquid consists of so constructing apparatus for that purpose that 78 [CHAP. IV. FIRST YEARS IN ENGLAND. the steam or other vapour, which is formed in consequence of the evaporation of the said liquid, is caused either to accumulate, or to be compressed into a smaller compass, whereby its temperature is increased, and it is made available to support the further evapo- ration of the same liquid by its own continued re-condensation, in consequence whereof a large saving of fuel is effected. According to this process, he stated, the vapour, "by a process of accumulation, is made to yield its latent heat continually back to the evaporating brine, and hence the effect of the fire may be multiplied indefinitely.” Mr. Siemens attached great importance to this inven- tion, and he hoped great things from its introduction on the Continent, where large salt and sugar industries were carried on, and where, fuel being dear, the importance of saving therein was very great. He had, as usual, explained the matter to his brother Werner, who fully entered into his views, and exerted him- self actively during some years to introduce the invention in Germany. Patents were taken out for many countries, and negotiations were opened in all directions with persons engaged in salt and sugar works and other industries to which the inventions might apply. But the manufacturers were, as the English ones had been, shy of adopting the novel process. It required an entire remodelling of their works, and a great outlay of capital, which they did not feel warranted in under- taking, without an unmistakable assurance of the success of the plan. Here lay the difficulty. The Messrs. Siemens obtained plenty of statistics; they used the most elaborate reason- ing to show the advantages that might be expected, and produced ingenious working-models in support of their views. But the manufacturers were obstinate in their re- CHAP. IV.] REGENERATIVE EVAPORATION. 79 luctance to be convinced; they ignored all the arguments, and said that small models might be delusive; they re- quired that positive and unquestionable results should be produced by trials on an actual practical scale, before they would embark their capital on the changes required. Werner saw the justice of these demands, and accord- ingly decided to erect, in Germany, at the cost of himself and his brother, a full-sized apparatus, which might be experimented on and perfected by themselves, and the results of which might be exhibited to those interested. This was done, and Frederick was sent over to superintend the work. It cost a great deal of money, and after all produced no result sufficiently favourable to make a com- mercial success. Meantime the attempts in the English market had been renewed. Towards the middle of 1850, Mr. Siemens went to Northwich, in Cheshire, and made some experiments on the application of his regenerative evaporator to some of the salt works there. These experiments were inquired into by Messrs. Fox and Henderson, who, having satisfied themselves on the matter, undertook to manufacture the apparatus along with the regenerative steam-engine. It was proposed to form a Company to work the in- vention, but the English salt-makers still hesitated to encourage the change, the advantages of which they con- sidered doubtful on account of the cheapness of their fuel. Messrs. Fox and Henderson, however, succeeded in obtaining an order to fit up an entire apparatus at the "Anciennes Salines Nationales de l'Est," at Lons-le-Saul- nier, in France. This was ready at the end of 1851, but it was stopped in London on account of some difficulties raised by the French Customs, and never reached its des- 80 [CHAP. IV. FIRST YEARS IN ENGLAND. tination. Mr. Siemens went to France to try to pass it, but without success, and the loss attending the transaction was the cause of much unpleasant discussion between him. and Messrs. Fox and Henderson. The relations between them had, indeed, become "strained" some time before; for the manufacturers, not finding the inventions turn out so profitable as they expected, had become somewhat less courteous to the inventor. The discomfort went on for some time; when the Lons-le-Saulnier losses and difficulties brought it to a climax, and Mr. Siemens's personal engagement with Messrs. Fox and Henderson was put an end to. ELECTRICAL WORK. After William had been a few years in England he com- menced the occupation on electrical business which after- wards expanded to such large dimensions. The early proceedings of himself and his brother in regard to electro-depositing have already been mentioned; but after William's departure for England, Werner took up the science of electricity in a wider sense, devoting special attention to the theory and practical construction of the electric telegraph, which was then scarcely known in Ger- many outside the circle of men of science. When it began to assume a practical shape, namely, about 1844, Werner brought his knowledge and inventive power to bear upon it. He designed telegraphs, and patented important im- provements in them, which soon became popular. He did not, however, at first manufacture them himself, the actual construction being carried out during the years 1844, 1845, and 1846, by arrangement with several manu- facturers, the chief of whom was the mechanic Leonhard, already mentioned as connected with the invention of the CHAP. IV.] 81 ELECTRICAL WORK. chronometric governor. In a letter to William of 3rd January, 1846, Werner gave particulars of his arrange- ments with these parties; he mentioned important works. in prospect, and declared his intention of devoting himself henceforward, heart and soul, to the promoting of this enterprise. On the 13th December of the same year he again wrote- I am now resolved to establish for myself a fixed career for tele- graphy. This will become a special and important branch of scientific engineering, and I feel that I have a call to take up its organization, as it is, I am convinced, yet in its infancy. One result of this "call" was the determination to set up a manufactory of his own, when the opportunity might arise. He had become acquainted with a mechanician named Halske, of whom he thought highly, but who was engaged in a manufacturing business with another person. It happened that, towards the middle of 1847 this partnership became dissolved, and Werner at once entered into negotiations with Mr. Halske, which re- sulted in the establishment of a factory in their joint names. As this was the small beginning of one of the largest and most successful undertakings of the kind ever known, and one eminently influencing William's career, it may be interesting to give the simple and modest chronicle of its rise and progress in Werner's own words, taken from various letters to his brother at the time. He says, in August, 1847:- I have now made a definite arrangement with the mechanician Mr. Halske (who has separated from his former partner) for the establishment of a manufactory, and hope that in six weeks it will be in full work. G 82 [CHAP. IV. FIRST YEARS IN ENGLAND. He explains how the necessary funds will be provided, and goes on- Mr. Halske, whom I have fully associated with me in the affair, will undertake the management of the shop, and I shall devote myself to the laying of the lines, the arranging of the contracts, &c. We shall for the present manufacture only telegraph instru- ments, signalling apparatus for railways, and wire insulated by gutta-percha. We shall, however, I think, call it a Machine Fac- tory (Maschinen Bau-Anstalt), in order to leave our hands free. The capital required is small; a few thousand thalers will suffice for the building, and we may, if we are fortunate, turn this over a hundred times in a year. Such a factory is urgently needed, and we are protected against rivalry by my patents, and the influence of my position, which is now considerable. After long seeking, a suitable locality has been found and engaged: the windows look upon the Anhalt Railway, which I shall in all probability have to provide with apparatus; this will be very con- venient, as we can test the instruments in the workshop. I live on the ground floor; the workshop is on the first storey, and Halske lives on the second. The work will begin on the 1st of October. On the IIth of that month he writes- I have now resided eight days in my new home, and a great deal of hammering and filing has been going on over my head. We are sadly off for machine-tools, as one of the lathes has given way, and we have only now one to use, though five were ordered. Halske is a thoroughly practical, clever, and good fellow, with whom I shall get on capitally, and whom I feel bound to bring honourably forward. On the 20th of December he says- Our factory is now fully occupied, and we employ ten men ; but Halske cannot leave his post, and we must get further assistance. In 1848-9, the firm undertook a large contract for tele- CHAP. IV.] 83 ELECTRICAL WORK. graphs from Berlin to Frankfort and Cologne; and in December, 1849, Werner wrote- The workshop now numbers thirty-two hands, and will soon be increased to forty-five; we can turn out four telegraphs a week, which will suffice for the next year... The orders promise to amount to six. I hope our time of trial is now over, and that life will now turn to us all its agreeable side. You, dear William, have certainly deserved it by your long and determined battle with its unfavourable circumstances. At the end of 1850 the factory was still more prosperous; money was plentiful, the firm having some £1,500 in their banker's hands, and great improvements were in full pro- gress. At the Great International Exhibition of 1851, in Hyde Park, Messrs. Siemens and Halske exhibited a large assort- ment of specimens of their telegraph work "as used on all Prussian Government lines, and on most of the railway lines of Northern Germany, making a total of about 3,000 miles, besides extensive lines in construction in Russia and other countries." Among these exhibits were a novel system of magneto-electric telegraphs with underground wires, and specimens of "gutta-percha coated electric line wire, first invented by Mr. [Werner] Siemens, and applied by him on a large scale since 1847." They were awarded a Council medal, and the system was spoken of in the Jury Report with high praise. At the end of 1851 the firm took much larger premises, costing them £7,500, and from that time forward their course was one of constant prosperity. The demand became very great, the contracts more numerous, and the nature of the work more comprehensive, until the establish- ment took a position as one of the chief centres for the application of electricity and magnetism in the industrial G 2 84 [CHAP. IV. FIRST YEARS IN ENGLAND. arts, and acquired, by the magnitude of its operations and the excellence of its work, a world-wide reputation. When Werner's telegraph work had begun to take a settled form, he lost no time in engaging William to co- operate with him by making his inventions known in Eng- land, and endeavouring to get orders for them; and on the establishment of the factory this co-operation became more desirable. William, therefore, undertook this duty, which was not inconsistent with his continued work at his inven- tions in Fox and Henderson's factory. About the middle of 1848 Frederick Siemens, who had for some time been acting as an assistant at Berlin, came over to England with samples of new machines and appa- ratus, and aided William in his endeavours to introduce them. On the 9th of June, 1849, Werner wrote to William as follows. Alluding to the execution of orders from England, he said- I do not know whether the English import duty is 10 or 20 per cent.; if the latter, it would be advantageous to make the work in England in order to avoid it. The construction of delicate machinery of this kind is but little cultivated in that country, as is shown by the fact that some of the most important scientific instruments wanted there have to be made either in Paris, or in Berlin, or in Vienna. I believe that at a future time you will yourself establish an engineering factory in England, and then we must arrange that you shall take up a branch of our electrical business, for which we will send you competent workmen, while we, in return, will work an engineering factory here to be laid down for us by you. It is true that for this purpose some hun- dred thousand dollars must be saved, but this may be done in a few years, if we go on as we have done hitherto. . . . For your English orders you shall soon receive telegraphs which will outdo all hitherto produced. You yourself shall name your share of the profits, but do not make it too small, for I would rather see tive CHAP. IV.] 85 ELECTRICAL WORK. > dollars in your pocket than two in my own. In no case should it be less than 10 per cent., when the apparatus is ordered from here. Werner's bold prediction as to the establishment of an English factory was afterwards, as we shall see, magnifi- cently realized. On July 30, 1849, William read a Paper at the Society of Arts describing his brother's construction of telegraphs. He illustrated the Paper by models and diagrams, and the description seems to have attracted considerable attention. In 1850 the English agency had become of so much importance that a more formal agreement was entered into for it as follows: LONDON, March 16, 1850. The undersigned have this day come to the following agree- ment:- Werner Siemens, for himself and in the name of the company "Siemens and Halske," gives over to William Siemens the agency, for England, of several inventions in the region of electro-magnetic telegraphs. William Siemens takes on himself the entire work and charge, and will carry out sales and other measures, according to his judgment, suitable to the purpose. and an The cost of patents, &c., will be borne by the company, advance of £210 has already been made to William Siemens for the purpose, the receipt of which he acknowledges. The profit arising out of the undertaking shall be divided as follows: viz., two-thirds of the net profits to Siemens and Halske, and one-third to William Siemens. For orders for apparatus to be made for England in the Berlin factory, William Siemens is to reckon 12 per cent. increase for his trouble. Further profits are to be divided as above described, in the ratio of 2: : I. If William Siemens is unable to devote sufficient time to trans- act all the business arising out of this contract, he shall employ 86. [CHAP. IV. FIRST YEARS IN ENGLAND. Frederick Siemens to assist him, and shall give him for such assist- ance one-quarter of his portion of profits. (Signed) WERNER SIEMENS, C. WM. SIEMENS. William's first work, under this agreement, was to intro- duce, in March, 1850, his brother's gutta-percha wire covering to the British Electric Telegraph Company, and a few months later he carried out an arrangement for working the manu- facture in this country. He further induced Messrs. Fox and Henderson to interest themselves in the telegraph work, and this led to large telegraph contracts being executed, partly by them and partly by Siemens and Halske, under William's direc- tion, on the Lancashire and Yorkshire railway and else- where.

HAVING now gained considerable experience, both technical and commercial, by his seven years' active though chequered life in England, Mr. Siemens resolved to enter into business on his own account. After leaving Birmingham he returned to London, and stayed some time at the Panton Hotel, Haymarket; but in March, 1852, he took an office at No. 7, John Street, Adelphi, with the view of practising as a civil engineer. He had already become pretty well known as an ingenious mechanical inventor, and, while he continued his exertions to introduce his most important inventions, he laid himself out to undertake any general professional work that would earn him money. Accordingly, during nearly the whole of this period, he had many things on his hands at the same time, and with 88 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. that versatility of resource so characteristic of him, he appears to have devoted to each the attention that it specially required, without neglect or confusion. It will facilitate the description of his labours to notice the various subjects separately. THE REGENERATIVE STEAM-ENGINE. The matter that occupied him most was his endeavour to apply the scientific principles of heat to a new form of steam-engine. We have explained in the last chapter the origin and nature of this, and have chronicled his un- successful efforts during several years to carry his idea into practice. Notwithstanding, however, the difficulties that attended these efforts he still persevered bravely. In 1852 he undertook, for his own satisfaction, an im- portant series of experiments on the total heat of steam and its expansion when in an isolated state, which he described to the Institution of Mechanical Engineers, on the 29th June, 1852. This was also translated into German, and published in "Dingler's Polytechnisches Journal." In the meantime he had been at work towards the practical construction of his engine, on which he had already been occupied with Messrs. Fox and Henderson. On October 9, 1852, he took out a patent for improvements in it, consisting generally of modifications of the former arrangement, combined with a peculiar heating apparatus, whereby he expected to obtain great strength to resist pressure at high temperatures, and a large development of heating surface in a narrow compass. Towards the end of 1852 he finished the modified design, and Messrs. Fox and Henderson, who still continued their practical interest in the invention, agreed to make a new CHAP. V.] THE REGENERATIVE ENGINE. 89 engine. Mr. Siemens resolved to devote, for a time, his whole attention to its construction and trial, and accordingly he took up his residence again in Birmingham, sending for his brother Carl, then in Paris, to undertake the duties of his London office. This work appears to have occupied him, more or less, from January till April, 1853. He then wrote to Messrs. Fox and Henderson long and full reports of his trials, and the results he had obtained. He stated that the principle involved had been " fully realized in its practical working," and that the engine had exerted considerable power; but that in its then incomplete state it was under several serious disadvantages, particularly losses by leakage, and he recommended its completion, with certain alterations. He now determined to make a new effort to interest the engineering world in what he was doing, and for this purpose he wrote another essay, of a much more advanced and elaborate nature than his former one, in order to explain the scientific principles on which his invention was based, and more generally the doctrines and practice affect- ing heat as a source of mechanical power. He presented this Paper to the Institution of Civil Engineers, and it was read there on the 17th May, 1853. It was entitled, "On the Conversion of Heat into Mechanical Effect," and was divided into three heads. The first, "On the Relations between Heat and Mechanical Effect," was, in fact, a somewhat elaborate exposition of the then new doctrine of thermo-dynamics, considered as bearing on practical engineering matters, and particularly on heat motors. The second head was, The second head was, "On the Perform- ance of Actual Engines, including Heated-Air Engines;' and the third was, "On the Necessary Characteristics of a Perfect Engine." The Paper showed great knowledge and "" 90 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. ability; it excited an interesting discussion, in which several eminent engineers took part,* and it received from the Institution the award of their Telford Silver Medal. It was afterwards translated into Italian, and published in Genoa, by the company formed at a later time to work the invention. In the meantime Messrs. Fox and Henderson had been considering the reports of the action of the experimental engine furnished them by Mr. Siemens, and his proposals in regard to its completion. They, however, viewing the question rather from a commercial than from a scientific point of view, were not satisfied as to the prospects of success it offered. They discussed the matter with him, and in July, 1853, an agreement was come to that. Mr. Crampton, an engineer of much experience in steam machinery, should be called in to give his advice on the subject generally. The result of this measure was a deci- sion, in which Mr. Siemens appears to have acquiesced, that the form of the engine was not favourable to the beneficial application of the principle; and it was agreed that he should prepare drawings for a new construction on an altered design. But This disappointment, after such long-continued labour, affected his health, and he felt the necessity of rest. he could not delay the engine matter, and he wrote to his brother Frederick, who was then at Stettin, instructing him to do what he could towards the preparation of the new drawings. In the beginning of September, feeling some- what better, he went to Berlin, and after a month of happy * At that meeting the author of this work undertook at some length the defence of Mr. Siemens's views respecting the action of the respirator, which had been called in question on that and former occasions. CHAP. V.] 、 THE REGENERATIVE ENGINE. 91 intercourse with his family, he returned to London fairly recovered. The designs for the engine took much time, and were not finished till March, 1854, when the drawings, fifteen in number, were submitted to Messrs. Fox and Henderson, and, after examination by them, were transferred to Mr. Hick, of Bolton, who had in this case undertaken the manufacture. The engine, which was of 15 horse-power, was tried in January, 1855, and the results showed con- siderable improvement. On the strength of this several other engines were made, varying from 5 to 40 horse-power, and were erected at various places in England, France, and Germany. Two of them, of 5 and 20 horse-power respectively, were shown and worked at the "Exposition Universelle," held in Paris in 1855, where the invention was awarded a First-Class Medal. The regenerator, according to Mr. Siemens's account, fulfilled its office with surprising perfection, and considerable economy of fuel resulted. Notwithstanding a break-down when the engine was exhibited before the Emperor, a French manufacturer, having watched its work- ing for some time, purchased it, after repair had been made, at a fair price. On the 11th April, 1856, Mr. Siemens described the engine in a lecture at the Royal Institution in Albemarle Street. After alluding to the dynamic theory of heat, he explained that, in an ordinary steam engine, viewed from the position of the new theory, only one-fourteenth of the total heat imparted to the boiler was really converted into mechanical effect, the remaining thirteen-fourteenths being lost, chiefly in the condenser. He then described his im- proved engine, which was, he said, the result of nearly ten years' experimental researches, and which he believed to 92 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. be the first practical application of the dynamic theory of heat for the purpose of saving fuel. He professed by its means to provide a motive force at one-third or one-fourth part of the cost and incumbrance of the present steam engine. In June he took out a patent for modifications of the details, and for the use of super-heated steam. The success of the engine at the Paris Exhibition at- tracted much attention to it on the Continent, from the promise it offered of a large saving of fuel, and a Conti- nental company was got up in the same year for the pur- pose of manufacturing the engine. It had its principal seat in Genoa, and was called the "Società Anonima Continentale, per le Macchine a Vapore, sistema Siemens,” and Mr. Siemens was the engineer. It appears to have been an affair of some magnitude, and to have had rami- fications in Paris, Vienna, Liège, and other Continental towns. The following letter to Mr. Siemens will show the feeling of the company towards him and his inven- tion :- MONSIEUR, GÊNES, 24 Novembre, 1855.

Agréez, Monsieur, ces sentiments avec lesquels j'ai l'honneur de me signer, Le Président du Conseil, NICOLAS BARTHÉLÉMY, Delle Vianetz. The company appear to have begun actively by con- structing engines in several places, among them being one at Stettin. This was tried in January, 1856, but it worked unsatisfactorily, and after a few days it broke down by the rupture of one of the cylinders. Mr. Siemens felt this misfortune severely; his sister wrote to him, on the 11th of January :- You complain of being sick in body and soul! Ah, William, do not take these business troubles too much to heart; I feared that the broken cylinder would give you a cruel blow; you are toc susceptible, too ambitious; there is nothing perfect in this faulty world. It was not, however, in his nature to be permanently discouraged by such an accident, for we find him at the same time pushing on the Russian and Polish patents for the invention; and he determined to go at once to Stettin to have the defect remedied under his own superintendence. He worked there some six weeks, and at the beginning of February some new disaster happened, which caused Werner to congratulate him on "having a whole skin.” 94 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. The engine was got to work again by the end of February, when, Mr. Siemens having returned to London, his brothers Werner and Walter, with Mr. Halske, made trials of it, but the results were not favourable. Another engine erected by the company at Beauvais also gave much trouble. The company desired to have a sample engine at their chief seat of business, and one of 4 horse-power was made for the purpose in Paris, and was erected in Genoa at the beginning of 1857, to work a flour-mill. It appeared to show great economy of fuel, and a commission of Italian government engineers, headed by the Minister of Public Works, Signor Paleocapa, was appointed to experiment upon it. But in spite of these hopeful prospects, complaints were continually made of leaks, destruction of working parts, undue consumption of fuel, imperfect action, and so on. In short, as Mr. Siemens remarked in one case, "nothing but bad luck" seemed to attend the engines, which all his per- severance and ingenuity failed to subdue. On the 24th of April, 1858, he wrote another long Report to be laid before the company at their annual general meeting. He stated that financial considerations had prevented any extensions, and that consequently he had only to report on the progress of work already in hand. He alluded to the difficulties encountered, which, however, he hoped would be removed by improved designs. But the speculation became more and more hopeless; the shareholders at length refused to make any further advances, and at the next annual meeting, in 1859, it was decided to abandon the enterprise and to dissolve the company.

Dans l'état actuel des choses et après les graves sacri- fices que nous tous avons faits pour la réussite de notre entreprise, je crois que la détermination qui a été prise est la plus conven- able et la plus judicieuse. Malgré tous nos efforts, nous n'avons pas pu réussir à obtenir une application utile et profitable pour la Société d'une invention qui a eu l'approbation des hommes les plus capables de l'époque (témoins le Rapport des ingénieurs nommés par le gouvernement de Piedmont). Les actionnaires se refusant au versement des sommes ultérieurs, il était impossible de maintenir les appareils, et de fournir aux dépenses nécessaires pour le maintien. Confiant comme je suis toujours dans la vérité de mon inven- tion, et dans le progrès futur de son application, je continuerai, avec mes moyens particuliers, et peut-être sous de meilleures con- ditions que celles d'une Société anonyme sans beaucoup de moyens, l'exploitation des machines à vapeur regénérée, et j'espère que la Providence voudra couronner mes efforts. Voulant témoigner à tous ceux qui se sont associés à cette entreprise et qui voulurent la seconder en prenant des actions, mon sentiment de reconnaissance et de justice, je viens par le présent à déclarer que, si par mes efforts particuliers l'invention sera productive dans l'avenir, je participerai aux actionnaires l'avan- tage que j'en tirerai en proportion de leurs actions et aux termes de l'acte de Société et des statuts approuvés par le gouvernement Sarde. * * * * Agréez, monsieur le Marquis, l'assurance de ma parfaite considération. C. W. SIEMENS. 96 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. Mr. Siemens kept his word as to following up the subject, for in August, 1860, he took out a further patent for intro- ducing the regenerative furnace and other novelties into the engine; but, as he said a year or two later,* "Many practical difficulties prevented a realization of the success which theory and experiment appeared to promise." In fact, notwithstanding all its theoretical merits, the regene- rative engine was pronounced, even by its talented inventor, a practical failure. REGENERATIVE EVAPORATION. Concurrently with his work upon the steam-engine, Mr. Siemens continued his endeavour to press forward the application of the regenerative principle to evaporation. In 1852 and 1853 attempts were again made to interest the Cheshire salt manufacturers in it, but without success, and at one time Messrs. Fox and Henderson seriously contemplated establishing salt-works on their own account at Gloucester. The experiments on the apparatus manufactured in Berlin were still continued at much expense, but without any satisfactory result. Werner said (6 April, 1853):— The evaporator gives us headache. Our improvements only make the result worse. I will try again to-morrow, but do not hope for success. A week later he recorded his failure, and offered to transfer the whole affair to another firm who were specially interested in salt and sugar works. These persons, how- ever, declined to proceed in the matter without William's personal aid, and so nothing further was done.. * Proceedings Inst. Mechanical Engineers, 1862, p. 22. CHAP. V.] THE REGENERATIVE FURNACE. 97 In 1853 and 1854 Mr. Siemens entered into negotiations with a mining company in Belfast, then newly established to work a salt bed at Carrick Fergus, and induced them to try the apparatus which had been made (as stated in Chap. IV.) for the Salines at Lons-le-Saulnier in France. The company hesitated a long time, in consequence of the Cheshire judgment against the new plan; but at length they agreed to work it for a year on trial, and to buy it if found successful. It was erected there accordingly at the latter end of 1855, but there is no record of its remain- ing permanently in use. In November, 1855, he applied for a further patent for improvements in the process by substituting a permanent gas for the vapour of the evaporated liquid; but this did not go beyond provisional protection. The prospects of the invention were not sufficiently encouraging to induce Mr. Siemens to devote more attention to it, and at last the regenerative evaporator, like the regenerative engine, died away. THE REGENERATIVE FURNACE. The failure of these heat inventions must have been even more disappointing to Mr. Siemens than those of an earlier period, inasmuch as he had better prospects of success. The regenerative principle was undoubtedly sound, and he had devoted ten or twelve of the best years of his life to its application, during which time he had the support of many eminent engineers, the practical aid of two of the best manufacturing firms in the country, and the funds of a powerful commercial association. Neither theoretical know- ledge, nor practical experience, nor ingenuity, nor skill, nor money, nor perseverance, nor influence, was wanting. H 98 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. But in spite of their promised advantages, the regenerative steam-engine would not supplant the simple machine of Watt, nor would the regenerative evaporator supersede the old-fashioned sugar and salt pans. It is hard now to explain these failures. Probably they arose from the aims being too high, and from the intro- duction of more complication than the nature of the machines would bear. In the steam-engine, for example, instead of the simple plan of evaporating and re-condensing water, in which the most ordinary mechanic could hardly go astray, there was substituted the alternate heating to a very high tempera- ture, and re-cooling, with the aid of the regenerator, of a permanent elastic fluid, which introduced not only a more elaborate construction, but new difficulties in the manage- ment, in consequence of the more intense heat applied in the working parts of the machine. And with the regenerative evaporator the more com- plex arrangements required larger outlay of capital, with greater trouble in working, and sometimes endangered the quality of the manufactured article. These difficulties were courageously attacked by Mr. Siemens's inventive ingenuity, and there is no doubt that in many cases satisfactory results were attained by the new machines; but on the whole the long and repeated trials showed that the complications and difficulties intro- duced were not commercially compensated for by the advantages gained in the saving of fuel. Such a heavy disappointment would have altogether disheartened many men, but it only served to bring out more prominently Mr. Siemens's strength of character. He relied on the soundness of the theoretical principles he had adopted as to the feasibility of heat saving, and simply CHAP. V.] THE REGENERATIVE FURNACE. 99 turned his attention towards other possible modes of carry- ing them into effect. In this effort he found an able coadjutor in his brother Frederick, who, as stated in the last chapter, had come over to England in 1848, and had been working with him during the whole of the experiments with the engine and the evaporator. During the year 1856, Frederick Siemens appears to have conceived the happy idea that the regenerative principle, which William had been so earnestly striving to carry into effect by complex arrangements of engines and evaporators, might be made available in a much more simple manner by applying it directly to the ordinary furnaces in which the fuel was consumed. It is often found, in tracing out the history of an inven- tion, that the simplest form is the latest in presenting itself to the inventor, and this case furnishes a striking instance of the fact. The new improvement was indeed, in principle, of extreme simplicity. It was well known that, in the working of powerful furnaces, the smoke and gases resulting from the combustion passed away into the atmosphere at a very high heat, while the air supplying the fire was drawn in at the ordinary atmospheric temperature. All therefore that the inventor here proposed to do, was to apply the regene- rative principle by means of a "respirator," so arranged as to intercept and absorb the superfluous heat from the escaping gases, and to give it out again in heating the air used to feed the fire. In this way not only would waste be prevented, but the intensity of action of the furnace might be much increased. The brothers studied the matter together, and William gave his powerful aid to the perfecting of the arrangements for carrying the invention into practice; but as the idea H 2 100 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. was Frederick's, it was necessary that the patent should be taken out in his name, and it was accordingly granted to "Frederick Siemens, of 7, John Street, Adelphi, London, Engineer," on the 2nd of December, 1856. William was always pleased to explain that the original merit of the invention belonged to his brother. The title of the patent was, for an "Improved arrange- ment of furnaces; which improvements are applicable in all cases where great heat is required." The chief object of this invention, namely, the application of the respirator, or regenerative" principle, was described in the first claim, for- (( Constructing furnaces in such manner that the heat of the pro- ducts of combustion is absorbed by passing the same through chambers containing refractory materials so arranged as to present extensive heat-absorbing surfaces; and is communicated to cur- rents of air or other gases by passing the latter currents alternately over the same heated surfaces. The principle was illustrated by a drawing of a heating- furnace. The products of combustion, after leaving the furnace, were passed through a "regenerative" chamber, containing fire-brick surfaces so disposed as to allow the current to pass freely amongst them, after which the currents, having parted with a large portion of their heat to the fire-bricks, passed away to the chimney. When the regenerator had become thoroughly heated, the fire-current was diverted from it, and passed into a similar one on the opposite side; and at the same time the atmospheric air intended to feed the fire was turned into the heated regenerator, passing through it in a reverse direction. By this means the cold air or gases were first brought into contact with the less heated material nearest the chimney, and subsequently with the more heated portions, until they CHAP. V.] THE REGENERATIVE FURNACE. ΙΟΙ finally passed over that portion of the surface which was nearest to the place of combustion, and which consequently became heated to the highest degree. The result of this arrangement was that the air, before it reached the fire, became heated nearly to the temperature of the fire itself, thus producing not only great saving of fuel, but almost unlimited power. While the air was thus entering the furnace through regenerator No. 1, the heated current passing away from the fire was heating regenerator No. 2; and when the former was sufficiently cooled, and the latter sufficiently heated, the two currents were reversed, by a simple damper apparatus, and so the alternation was effected from time to time as required. The patent showed a variety of furnace for using car- buretted hydrogen, or other inflammable gas, instead of solid fuel; and also other variations in the applications of the principle. The invention was described by William in a Paper read by him before the Institution of Mechanical Engineers, on the 24th June, 1857; and as this was his first public announcement of an apparatus which afterwards turned out of such great importance, the following extracts may be interesting :- The high importance of the stores of combustible material which are distributed upon the surface of the earth, renders their wasteful expenditure and rapid diminution in quantity in many parts a serious subject for consideration; and in the writer's opinion, there is no object more worthy of the earnest attention of engi- neers and men of science generally, than that of causing the generation and application of heat to be conducted on scientific and economical principles. Our knowledge of the nature of heat has been greatly advanced of late years. . . . If we investigate the operations of melting and heating metals—and indeed any opera- tion where intense heat is required-we find that a large pro. I02 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. portion of heat is lost, amounting in some cases to more than 90 per cent. of the total heat produced. Impressed by these views, the writer has for many years devoted much attention to carrying out some conceptions of his own for obtaining the proper equivalent of effect from heat; some of the results he has obtained are known to the members of this Insti- tution. The regenerative principle appears to be of very great importance, and capable of almost universal application, and the object of the present Paper is to describe an application of this principle to furnaces of every description. The invention of the regenerative furnace is due to the writer's brother, Mr. Frederick Siemens, and it has been matured and variously applied by the writer within the last few months. The result has in all cases been a large saving, amounting to from 70 to 80 per cent. of the total quantity of fuel hitherto consumed. The apparatus employed is, moreover, of a very simple and permanent description, and combines economy of fuel with other advantages, amongst which are the total prevention of smoke, and a general improvement in the quality of the work produced. The first experiments were carried out by the two brothers with a furnace they built for the purpose in Scotland Yard; but furnaces on a full practical scale were erected and worked under the management of Frederick Siemens, in the beginning of 1857, at the steel works of Messrs. Marriott and Atkinson, Sheffield, to be applied to the melting and re-heating of steel; and at Messrs. Lloyd, Fosters, and Co.'s works at Wednesbury, in Staffordshire, for the re-heating of iron. These were successful, the saving of fuel being very large, much greater than was expected; but many formidable difficulties had to be overcome, in particular the providing of materials sufficiently refractory to withstand the more intense heat produced. Experiments, therefore, were carried on, principally in Sheffield and Staffordshire, for some -years, during which, in May, 1857, William took out a • CHAP. V.] THE REGENERATIVE FURNACE. 103 patent in his own name for practical details required to render the furnace applicable to certain special purposes. These experiments were in progress at the time of the final collapse of the engine and evaporator, and the pro- mise of their success no doubt tempered the blow, which otherwise would have fallen so heavily upon him. In the mean time an important and very successful application of the furnace had been made to the heating of the air for hot-blast iron smelting furnaces. This was suggested by Mr. E. A. Cowper, and was patented by him in 1857. The regenerator had to be made to work under considerable pressure of air; and to fit it for this purpose, it was enclosed in a fire-brick lining, which was placed inside a wrought-iron air-tight casing, capable of resisting the pressure of the blast, while the brick lining resisted the heat. Mr. Siemens fully appreciated the arrangement, which he called "one of the most interesting applications of his furnace;" he gave Mr. Cowper all possible assistance, and his name appeared in one of several later patents, taken out for its improvement. It was largely applied in almost all iron-making countries, and its advantages were thus summed up by Mr. Siemens :- No wear and tear of pipes. No leakage (which in the ordinary stoves amounts to 20 per cent.). Increased make of iron from the same furnace and the same amount of blast used. Large saving of fuel used to heat the air. Still larger saving of fuel in the furnace itself, owing to the increased temperature of the blast, which is commonly raised to 1500°. These savings over the whole iron manufacture of the 104 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. world are said now to amount to about half a million sterling per annum ! REFRIGERATION. As an instance of how thoroughly Mr. Siemens had studied the theory of heat, it may be mentioned that he did not neglect what may be called its negative phase, namely, the operation of cooling or refrigerating. He appears to have discussed this matter with his brother Werner as early as 1852; and some experiments were made with the aid of Frederick, but nothing was practically done till 1855, when he took out a patent (30th October, No. 1,105) for "Improvements in cooling and freezing water and other bodies." It was based on the decrease of temperature in the dis- solving of certain chemical salts. Water was caused to percolate through a mass of crystalline chloride of calcium, and as the solution became reduced in temperature, it was used to cool other bodies, such as bottles of water, and so on, by circulating round them. The patent showed an ingeniously-contrived machine for the purpose, and the details of the process were further improved by another patent on the 13th September, 1858. On the 29th July, 1857, he had applied for a patent for cooling by the expansion of air (since so much used), but it was not proceeded with. In 1857 he had one of the machines constructed at his workshop in Millbank Street, Westminster, and the process was adopted with some success on the steamers of the Peninsular and Oriental Company. Some machines were also made for breweries; but the invention did not come into extended use. CHAP. V.] 105 THE WATER-METER. THE WATER-METER. The first real and unequivocal success that Mr. Siemens achieved after he had taken up his residence in England was an invention that he brought out in 1851, namely, a new kind of meter for measuring water. About the middle of this century a great sanitary move- ment took place, and as a consequence attention was prominently directed to the water-supply of towns. Public inquiries were set on foot, and legislative measures were enacted for improvements in the supply. Dissatisfaction was expressed with the mode of distributing water into houses, particularly as to the great waste that was found to occur, and, acting on the analogy of gas distribution, a desire was expressed that water should be supplied by meter. But although many attempts had been made to devise a machine which should register the quantity of water delivered, no such machine had been constructed in which the selling and buying parties could place confidence.* Mr. Siemens saw the want, and appreciating the advantages which a successful water-meter would offer, both to the public and to the inventor, he determined to tax his ingenuity to solve the problem. As early as 1845 he had imagined an ingenious con- trivance which, by the aid of clockwork, should register the flow in a given time through a weighted valve, but the necessity for winding up the clock made this too trouble- some for general use. He then proposed to do the wind- ing by a screw-propeller turned by the water-current; * See Proceedings of the Institution of Civil Engineers, vol. xvi., page 60. IC6 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. but as soon as he began to develop this idea it flashed on his mind that if the screw could be made to rotate, as was highly probable, with a velocity proportionate to that of the water-current, all the complications of the loaded valve and clockwork might be dispensed with, and the screw itself might be made to serve as the meter, without any other paraphernalia, except the ordinary means of recording the revolutions. Thus arose the idea of a meter to be formed by placing an endless screw, or system of helical vanes, suspended on two points in the axis of a moving cylindrical column of water. The inventor, however, saw that there would be many practical difficulties in getting such an apparatus to be trustworthy, and the execution of it was delayed some years. At the beginning of 1848 he asked his friend Mr. Woods what he thought of the idea of a "revolving meter pump," and the reply was favourable. Still, however, nothing practical was done till 1851, when after many trials, with the aid of his brother, at the Berlin manufactory, he succeeded in producing a model that gave promising results. Armed with this, he made application, through a Mr. Schwabe, a friend in Manchester, to the Corporation of that city, who appointed a committee of inquiry to examine the invention, the result being that they ordered six meters on the new plan, to be tried for two months, and then to be paid for if they worked satisfactorily. He had obtained an advance of £250 from Mr. Schwabe to enable him to try experiments, and he put the work into the hands of a firm of high reputation for the manu- facture of water fittings, Messrs. Guest and Chrimes of CHAP. V.] 107 THE WATER-METER. Rotherham, who took from Mr. Siemens a formal licence to make and supply the meters in case the invention should succeed. The meters for Manchester were completed in the spring of 1852, and worked so well as to justify Mr. Siemens in lodging a patent for a "Fluid Meter," which was dated. the 15th of April in that year. This simply carried out in various modifications the principle before named, the inven- tion being stated to consist in- Various arrangements of screws or helices, which are caused to revolve by the passage of water or other fluid through them, and of fixed guides and channels in connection with such screws or helices to regulate and direct the current of the fluid, together with various contrivances for registering the number of revolutions of the screws. The patent contained also an application of the same principle to forming a screw log for measuring the speed of a ship through the water—a contrivance since much used. But though the principle was simple, its suitable appli- cation in a practical form needed great ingenuity, and its inventor had to bestow much study upon it before the most effective and trustworthy arrangement could be de- vised. The experiments and trials for this purpose were partly carried on in the Berlin factory, and partly by Guest and Chrimes. They occupied some time, and led to a second patent for improvements dated the 23rd March, 1853. This was taken out in conjunction with a Mr. Joseph Adamson, an engineer of Leeds, who had about the same time directed his attention to water-meters, and had already brought out some inventions in regard thereto. Mr. Siemens had examined these, and an arrangement was made that the new improvement should be protected in their joint names. 108 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. This patent for "Improvements in Rotatory Fluid- Meters" introduced a plan considerably differing from the former one, being an application of the principle of re- action, previously used for hydraulic purposes in “Barker's Mill" and the "Turbine," both which forms were included in the patent, as well as one resembling an ordinary under- shot water-wheel. The Barker's mill form proved ulti- mately to be the most useful for general practical purposes, and was almost exclusively the one sold. Its construction is shewn on the Plate, which has been kindly furnished for this work by Messrs. Guest and Chrimes. The simplicity and efficiency of this contrivance caused it to be soon appreciated. As early as August, 1852, above a hundred meters had been ordered, and the sale increased fast. It was not only adopted extensively in many towns in England, but it also excited much attention on the Continent and in America. 1 In January, 1854, Mr. Siemens read a Paper, on water- meters generally, before the Institution of Mechanical Engineers, and this was followed by a later one on the 30th July, 1856, when he described the improved construction of meter definitely adopted. On December 2nd of the same year the subject was also discussed at the Institution of Civil Engineers,* when Mr. Siemens made some remarks explanatory of his own invention, stating that he had been the first to bring into use a meter which would work with a high water-pressure. Meters of various kinds were discussed at considerable length, and that designed by Mr. Siemens was spoken favourably of by several eminent waterworks engineers. Some further patents were taken out by Mr. Siemens * Minutes of Proceedings Inst. C.E., vol. xvi., p. 46. b H ao PERSPECTIVE VIEW OF DRUM. THE WATER METER. W SECTION OF METER.

The prompt success of this invention was a most fortunate thing for Mr. Siemens, for in 1853, although the patent was only a year old, it was beginning to bring him in a handsome income, and so relieved him from the pecuniary anxieties he had suffered, more or less, ever since he had come to England. The demand and sale continued to increase, and the royalties received by Mr. Siemens for the sale in Great Britain alone amounted for many years to above £1000 a year; in addition to which there was a considerable income from meters made on the Continent, the invention being protected there also. The following excellent remarks on the scientific merits of the invention are taken from a notice written by Sir William Thomson for the Royal Society: The Water-meter exactly met an important practical requirement, and has had a splendid thirty years' success. It applied curiously subtle hydraulic principles, which, even irrespectively of the practical value of the instrument, are of great interest. Imagine a Barker's mill running absolutely unresisted. The discharged water must have approximately zero absolute velocity on leaving the nozzles; in other words, its velocity relatively to the nozzles must be approximately equal to the contrary absolute velocity of the nozzles. Hence the machine will rotate in simple proportion to the quantity of water passing through it. By an extension of similar considerations, it is easy to prove that if the wheel, instead of being unresisted, is resisted by a force exactly proportioned to the square of its angular velocity, its velocity must still be proportional to the quantity of water passing through per unit of time. Thus, provided this law of resistance is main- tained, the whole angle turned through by the wheel measures the whole quantity of water that has passed. Now think of the diffi- culties which Siemens had to overcome to apply this principle. IIO EARLIEST INDEPENDENT PRACTICE. [CHAP. V. What has been roughly called a Barker's mill must be completely inclosed in the supply water-pipes, its nozzles discharging into water, not into air. It must be of very small dimensions to be convenient for practice, and its bearings must be kept oiled to secure not only that it may not be injured by the wear of running for years, but also that the constant frictional force of solid rubbing on solid may be as nothing compared to the resistance, proportional to the square of the velocity, exerted by the circum- ambient liquid upon a wheel with sharp-edged vanes rotating in it. After a few years of trials, difficulty after difficulty was overcome, and the instrument did its work with the accuracy and conve- nience which met practical requirements. It was, we believe, the protection offered by the British Patent Law which, in the case of this very instrument, allowed Siemens to work it out in England, and so helped him eventually to find his home among us, and to give us primarily the benefit of his great inventiveness in all directions; while the want of similar pro- tection under German law at that time rendered it practically impossible for him to work out so difficult an invention in his own country. In a practical point of view the Siemens water-meter has been one of the most useful and valuable machines ever brought into hydraulic engineering; nothing has been dis- covered superior to it for the special objects it is intended to serve, and no material improvement has been made in it since it received its final form under the patent of 1853. It is still largely used. Down to the end of 1885, nearly 130,000 meters had been sold by Messrs. Guest and Chrimes alone, and in many cases it has been established as the standard apparatus for the sale of water. SMALLER INVENTIONS. The Chronometric Governor.-Although difficulties and failures had often occurred in applying this invention, yet Mr. Siemens seems to have had encouragement enough to CHAP. V.] III LEAD PIPES. > persevere in regard to it; it continued to be used to some extent, and formal licences appear to have been granted to several firms in various parts of England for supplying the governor, Messrs. Hick of Bolton taking the principal management of the business. In 1853, in order to bring the merits of the invention more prominently before the world, he presented a Paper to the Institution of Mechanical Engineers, which was read at the meeting in Birmingham on the 27th of July of that year. It continued to be tried to some extent; but although the beauty and ingenuity of the invention were unquestion- able, it was of greater sensitiveness than was required in ordinary steam machinery, and it did not come into general use. It was, however, applied with success to more delicate purposes; for example, to regulate the motions of chrono- metric instruments in the Observatory of Greenwich. The late Astronomer-Royal, Sir G. B. Airy, originated this application, with Mr. Siemens's concurrence, and it has remained in use to the present time. The subject of uniform motion had a great attraction for Mr. Siemens, and he returned to it at a later period. Manufacture of Lead Pipes.-On 29 March, 1859, he exhibited, at the Institution of Civil Engineers, a machine of his own invention for joining lead pipes, by pressure only between the surfaces of metal, instead of soldering. He and Werner had given much attention to the use of lead pipes, as a covering protection to underground electric cables; and this improvement had arisen in the course of their experiments. II 2 EARLIEST INDEPENDENT PRACTICE. [CHAP. V ELECTRICAL WORK. When Mr. Siemens commenced practice on his own account in London, he was better able to carry on the electric telegraph work which he had taken up shortly before, and this work had the great advantage that it was a source of income free from risk. He now therefore exerted himself actively to push the interests of the Berlin manufacturing firm, to introduce his brother's inventions, and generally to further electrical operations in this country. On March 2, 1852, and at the two following meetings, the subject of electric telegraphs was discussed at the Institution of Civil Engineers, and Mr. Siemens contributed to the discussion a long and detailed account of the tele- graph in Germany. He stated that the arrangements of the instruments and wires which had been adopted and executed by his brother, to a large extent, in that country and other parts of the continent, differed essentially from other systems. He described, by the aid of specimens and models, the German pointing and printing telegraphs, the latter of which printed the messages given and received in common type on slips of paper, thus giving a duplicate record of the communications, legible by everybody, at both ends of the line, and avoiding all possibility of error. He further alluded to the peculiar system adopted of laying the wires, and described the means used for dis- covering and correcting defects in the insulation. This was the first important communication Mr. Siemens made to the Institution, of which he became afterwards so distinguished a member. In the same year he spent some time in Paris, endea- vouring to establish an agency there, his negotiations afterwards being continued by his brother Carl. CHAP. V.] v.] . 113 SUBMARINE CABLES. When in the autumn of 1853 he went to Berlin for the benefit of his health, his communications with the firm. there led to a change in his relations with them. Hitherto he had been simply an agent, but it was now arranged that he should become a partner, and that the English work should be elevated to the character of a distinct branch of the electrical business, under his personal management. We find him accordingly undertaking works of considerable magnitude, among which were, at various times between 1853 and 1856, the furnishing of large sup- plies of materials, instruments, and apparatus for the Government telegraphs in India. About this time a new description of telegraph work sprang up, which, as it soon assumed great magnitude, and formed indeed for some time the most important electrical subject of Mr. Siemens's attention, it is desirable here to mention somewhat fully. This was the establish- ment of telegraph communication across the seas by means of submarine cables. The Siemens family were connected, more or less, with this matter from the time of its introduction. When electrical telegraphy was first designed, the conducting- wires through which the motive agency passed were placed in the air, supported on posts, with insulators attached. The air, under ordinary circumstances, was also a non- conductor, and this was the simplest means of effecting the required insulation. In 1846, however, the remarkable non-conducting pro- perty of gutta-percha was discovered by Werner Siemens, and having regard to its great plasticity and ease of mani- pulation, he proposed to use it for covering telegraph wires, in order to be enabled to lay them underground, which he conceived would be a more secure system. In the spring I 114 EARLIEST. INDEPENDENT PRACTICE. [CHAP. V. of 1847 he proposed this system to the Prussian Govern- ment, and having completed successfully, in the autumn of that year, the first experimental line of 20 miles long, his plan was adopted, and in the years 1848 and 1849 about 3000 miles were so laid. This system has since been most successfully applied. It has not superseded overhead wires, but has divided the telegraph world with them. Each system has its peculiar advantages, and both are largely used. It soon occurred to Werner Siemens that his method of insulation would admit of the conducting-wires being carried not only through damp ground, but actually through water-an almost perfect conductor; and, to prove the correctness and practicability of his idea, he, in March, 1848, submerged in the bay of Kiel several miles of copper wire, coated with gutta-percha, to establish an electric communication between the shore and several points in the deep channel, where mines had been laid for warlike pur- poses; and this was undoubtedly the first attempt ever made to establish electric submarine communication. About the same time also he carried successfully a sub- merged telegraph-wire across the Rhine from Deutz to Cologne.* The idea was too valuable to be let sleep, and it was clearly the province of England, in her insular position, to take the earliest advantage of it. The question of forming a telegraph communication between England and France had been often mooted, and in 1847, Mr. Jacob Brett, an eminent English telegraph engineer, had obtained a pro- visional concession from the French Government for the * These data were communicated by Mr. Wm. Siemens to the Institution of Civil Engineers, in a discussion on submarine telegraphs, 13th January, 1857. CHAP. V.] 115 SUBMARINE CABLES. purpose; but the practicability of the project being doubtful, the concession was allowed to lapse. Werner Siemens's proceedings had now changed the aspect of matters. In 1849 a successful experiment was made off Dover by Mr. C. V. Walker, the electric engineer of the South Eastern Railway, and, a second concession being obtained, on the 25th August, 1850, a submarine cable was actually laid across the strait from Dover to Cape Grisnez. It consisted simply of a copper wire covered with gutta-percha, but without any further protection; it was about half an inch in diameter, and was loaded with lead to keep it down. The communication was effectual, and a few complimentary messages were transmitted across; but on the following morning, when the French official engineers arrived to test the communication, the wire refused to act, the Government declined to believe it had ever done so, and the concession was cancelled. The mystery was afterwards explained. A diligent French fisherman, plying his vocation off Cape Grisnez, picked up the cable in his trawl and cut off a piece of it, which he bore in triumph to Boulogne, exhibiting it there as a specimen of a rare sea-weed with its centre filled with gold! This curious accident gave an indication that another condition beside the sufficient insulation was necessary, namely, that the cable must be protected-a condition which ever afterwards was deemed of supreme importance, and received great study. But, for the time, the difficulty produced great disappoint- ment and discouragement to the enterprise; a third conces- sion was obtained in 1851, and the "Submarine Telegraph Company" was formed, but the scheme was viewed unfa- vourably by several engineers in England, and all the French engineers declared it to be impossible. Contractors noted for their enterprise and liberality refused to under- I 2 116 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. take it, and the public, when applied to for funds through an excellent direction, liberally subscribed to the extent of £300. At length, when the concession had only seven weeks to run, an engineer and contractor, the late Mr. Thomas Crampton, who had been much engaged in the formation of the London, Chatham, and Dover Railway, and who was deeply interested as a shareholder in the Submarine Com- pany, came forward. He professed perfect confidence in the feasibility of the scheme, and volunteered, not only to execute the work, but to provide half the necessary capital. His offer was accepted; in seven weeks the means and manner of carrying out an undertaking such as had never been known before, were devised; the form of cable suit- able to all the requirements of the case was designed; the machinery for its manufacture was invented and made; the cable itself was spun; and on the 25th September, 1851, it was laid across the Channel with perfect success. It was 24 miles long, consisting of four copper wires, insulated by gutta-percha, covered with tarred yarn, and protected by an outer covering of galvanized iron wires. It has remained perfect to the present time, and still forms one of the communications between the two countries. After submarine telegraphy had thus become an accom- plished fact, it naturally extended in all directions. In 1853 a cable 60 miles long was laid between Dover and Ostend; and another 115 miles long, between Orfordness, in Suffolk, and Scheveningen, in Holland; and, England having led the way, the example was speedily followed by foreign governments. Skilful engineers took up the subject, and subaqueous telegraphs began to multiply in all parts of the world. It was impossible that, among the engineers engaged in CHAP. V.] 117 SUBMARINE CABLES. this new branch of electrical practice, the Siemens family should keep in the background, and the manner of their active introduction into it was as follows. The firm of R. S. Newall & Co. of Gateshead-on-Tyne, large wire-rope makers, seeing the great demand arising, had laid out works for the construction of submarine cables on an extensive scale. They saw also that the design, con- struction, and laying of submarine cables, were opening out very difficult questions, both of electrical science and engineering practice; and they wisely determined to secure the aid of persons specially skilled in these subjects. Their choice could not have fallen on better coadjutors than the Messrs. Siemens. They therefore formally engaged the firm of Siemens and Halske to act as electrical and consulting engineers for them in the matter of submarine cables. In this capacity Messrs. Siemens, during 1858 and 1859, carried out the electrical tests, and assisted at the laying of many of the earlier cables, among which may be mentioned those- From Bona, in Algeria, to Cagliari, in Sardinia, for the French Government; From Cagliari to Malta and Corfu for the Mediterranean Extension Company ; From the Dardanelles to Scio and Candia, for the Levant Company; From Syra to Scio, for the Greek Government; From Singapore to Batavia, for the Dutch Government; From Weymouth to the Channel Islands; From Suez to Suakim and Aden, and from Aden to Kurrachee, for the Red Sea and India Telegraph Com- pany. When the Red Sea cable was laid, Werner Siemens 118 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. went out specially to aid in the operation, and in returning home he was one of the sufferers in the memorable ship- wreck of the Peninsular and Oriental steam-ship Alma. This vessel left Aden for Suez at 6 A.M. on the 11th June, 1859, having about 400 persons on board, among whom were several gentlemen who had been engaged in laying the telegraph, including Mr. Newall, his partner, Professor Lewis Gordon, Mr. Lionel Gisborne, the chief engineer of the Telegraph, and Mr. Werner Siemens. In the middle of the following night the vessel struck on a coral reef in the Red Sea, part of which was above water. The passengers and crew were landed hastily on the reef, and after enduring great sufferings and privations for three days, were rescued, without any loss of life, by H.M.S. Cyclops. A full account of the disaster was given in the Times of the 7th July, 1859. It may be well imagined what intense anxiety was suffered by the families until the safety of their relatives was ascertained. William Siemens took an important part in the work for Messrs. Newall, and was responsible for the electrical testings, though he did not, in any cases, attend the laying. He also now began to apply his own inventive powers to electrical work, and we find patents taken out by him in 1854, 1856, 1858, and 1859, for improvements of various kinds in telegraph detail, either his own or communicated by his brother Werner. For some years after the institution of the London branch of Messrs. Siemens and Halske's firm, the apparatus used in the telegraphs was either made in Berlin or procured from manufacturers in England. But as the orders began to extend considerably, the question arose whether it would not be advantageous to set up a special CHAP. V.] 119 FACTORY IN ENGLAND. workshop in London, according to the idea expressed by Werner Siemens some years before.* On the 28th October, 1856, William Siemens, in writing to Dr. O'Shaughnessy, the East Indian Government Agent, said :- It is fully my intention, being a resident in this country for many years, to put up an establishment for the manufacture of telegraph materials in this country, as soon as there will be a sufficient demand for them. And in the following July he made, writing to another party, a similar statement. In the next year, 1858, he took steps to carry out this idea. He found some premises at No. 12, Millbank Row, Westminster (near the site of the present Lambeth Bridge), which he thought would be suitable, and, with the co- operation of the Berlin firm, he had them fitted up with the necessary tools and provisions. A skilled and expe- rienced assistant from the Berlin Works, Mr. Mittelhausen, was sent over in October, 1858, to aid him in the laying out and management of the place, and it was ready for work by the end of the year. This little factory was capable of employing some 80 to 100 workmen; and it was used principally for the manu- facture of the smaller descriptions of telegraph work, such as instruments, batteries, insulators, and so on. But it had also another object to which Mr. Siemens attached much importance, namely, to provide him with a convenient locality for carrying on experiments connected with the new inventions and improvements which his prolific genius still prompted him to contrive. He had been obliged hitherto to make use, for this purpose, of con- * See page 84. 120 EARLIEST INDEPENDENT PRACTICE. [CHAP. v. veniences afforded by other manufacturers; but it was far more advantageous to have a place where he could effect his trials in security against prying curiosity, and under his own personal supervision. In these premises were elaborated the details of many electrical novelties, of furnace arrangements, of the refrige- rating machines, the pyrometer, the resistance measurer, the bathometer, and of many other novelties, which went successfully before the world; and here were strangled in their birth any unfortunate offspring of Mr. Siemens's brain which had not the power of competing in the struggle for existence. The Millbank workshop continued in use till 1866, when it became merged in the larger establishment that will be spoken of in the next chapter. } DOMESTIC LIFE. Something should now be said on Mr. Siemens's private and domestic life during this period. In the first years of his residence in England he had no settled home. While in London, fighting with the early troubles of his patents, he lived in modest lodgings, giving his business address at the offices of his friend Mr. Woods, in Barge Yard, Bucklersbury. Then came his roving occupations in the provinces, and his engagement with Messrs. Fox and Henderson, after which, on settling in London, in 1852, he made arrangements to board, conveniently near his office, at No. 7, Adelphi Terrace. Here he entered the family of Mr. William Hawes, a well-known professor of music, one of the vicars choral and master of the boys at St. Paul's Cathedral, and the father of the celebrated contralto singer Maria B. Hawes. During his residence with that family he CHAP. V.]. 121 DOMESTIC LIFE. had, in 1853, a very severe illness (typhus fever), and was most kindly nursed by the members of it, as also by his friend, Luigi Scalia, who was as a brother to him. He never ceased to remember with gratitude the kind treat- ment he received at that time. He remained with Mrs. Hawes till 1854 or 1855, when, his prospects beginning to look brighter, he rented a house. on his own account in Kensington Crescent, taking his brothers, Frederick and Otto, to reside with him. Here he lived till his marriage. His love for the country and pure air determined his homes-which were always, if possible, within the sight of green trees. He was now able to make himself more known in general society, and to receive friends in an unassuming way, having, in the midst of his manifold and anxious work, always time for kind thoughtfulness of others. Hospitality was indeed then, as in all his subsequent life, a part of his nature. The friends he chose were usually men of capability, and having an aim in life. He was well acquainted with many of the eminent foreigners who sought refuge in this country after the political convulsions of 1848. Among them were Semper, the renowned architect, Richard Wagner, Bucher (with whom he was intimate, although not agreeing with his political views), Kinkel, whose son he at a later period took into his employment, and the brothers Luigi and Alfonso Scalia, with whom he formed a true friendship that never flagged, even after the brothers left for Italy to join the ranks of Garibaldi. He visited at the houses of many friends, where he occa- sionally met men eminent in literature, art, or science, and in this way he became personally intimate with many of the leading men among his professional brethren. 122 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. With their encouragement and support he now formally enrolled himself among them by joining the Institution of Civil Engineers. He had, indeed, applied much earlier, in 1846, but could not then be received, being under the required age of twenty-five. His election to the grade of Associate came off on the 4th April (his birthday), 1854. He was described as having been "for the last three years in business on his own account, occupied in the establishing of extensive lines of submarine and other telegraphs on the Continent, and in other works." He was proposed by Sir Charles Fox, and seconded by many distinguished men in the profession. Among the engineers with whom he formed acquaint- ance was Mr. Lewis D. B. Gordon, the son of Joseph Gordon, Esq., W.S. of Edinburgh. This young man had been educated as a civil engineer, and had so distinguished himself in science, that at the early age of twenty-four he had been appointed to the important post of Professor of Engineering in the University of Glasgow. He was also practising his profession in London, and it happened that, like Mr. Siemens, he was much engaged in electrical pursuits. The similarity of occupations and scientific tastes led to a close friendship between these two young men, which was further encouraged by Mr. Gordon's having married a Hanoverian lady, in some measure connected with Mr. Siemens, her sister being the wife of his cousin Herr Oberamtsrichter Gustav Siemens of Hanover. As early as the year 1851 negotiations had been going on for a permanent association between Mr. Siemens and Professor Gordon in a large and important electrical under- taking; and although this did not come about, they were frequently coming in contact, in business matters, through CHAP. V.] 123 NATURALIZATION IN ENGLAND. Mr. Siemens's transactions with the firm of Newall and Co., in which Professor Gordon was a partner. A personal friendship was thus formed which led to an intimacy between Mr. Siemens and the other members of the Gordon family, and this ultimately ripened into an attachment between him and Miss Anne Gordon, the youngest sister of the Professor. He now determined to naturalise himself in this country, where henceforth all his interests would be centred; and on the 19th March, 1859, as he used amusingly to say, he took oath and allegiance to two ladies in one day—the Queen, and his chosen partner in life. Two extracts from letters written during his engagement may be given. Miss Gordon was an educated singer (a pupil of Manuel Garcia), and had been suffering from a cold. He said- Your letter has indeed been a heart's pleasure to me, telling me as it does that your health, and even your voice, is fast coming back; for after all, the singing canary is preferable to the moulting one, however much one may prize the bird for its other qualities. Again, after she had expressed an interest in the re- generative engine, he wrote— How happy I am that you feel an interest in my engine as well as in myself. My inventions are the children of my thoughts, whose education has yet to be completed, and you will be a kind stepmother to them, will you not? The marriage was delayed some time in consequence. of the shipwreck of Werner Siemens and Professor Gordon in the Red Sea, but, on their safe return, it took place at St. James's, Paddington, on the 23rd July, 1859. The couple at once set off for Germany, that the family 124 EARLIEST INDEPENDENT PRACTICE. [CHAP. V. might become acquainted with the English member who had entered into it. The marriage was a thoroughly happy one. Everyone who had afterwards the privilege of introduction into his house well knew what a "helpmeet" he found in the wife of his choice, and how his labours were lightened by the cheerful home she made for him. They took a pleasant little villa near Twickenham, where they lived between three and four years. The following extracts from some of the congratulatory letters he received, will show how this important step in his life was viewed by his own family. From his Brother WERner. VIENNA, 24th March, 1859. As I was just packing up I received your great, long-expected, news! Receive my most heartfelt congratulation. May every joy and blessing spring from your anticipated marriage! Give also to your dear fiancée, whom I joyfully welcome as my future sister-in-law, my fraternal greeting. Anne Gordon has always appeared and been described to us as so liebenswürdig, klug und brav, we can only congratulate you on having won her. I hope in the summer to have the opportunity of knowing her better; so settle definitively, and bring her, as your young wife, to your old home! She will certainly have a hearty welcome! From WERNER'S Wife. BERLIN, 29th March, 1859. You could not, dear William, have given us greater pleasure than you did by your letter of yesterday.

AFTER his marriage Mr. Siemens appears to have made a new start in life, with increased vigour. His prospects were certainly brighter than ever they had been before. In the first place he had a highly successful invention, the water-meter, in full work, which, without trouble to him, was bringing him in a fair income. Secondly, in regard to the heat applications, he had now thrown aside the ineffective machines which had given him so much anxiety and disappointment, exchanging them for the Regenerative Furnace, the success and popularity of which seemed almost certain. Then, thirdly, he had an excellent position in his electrical work, which ensured him good and certain remuneration, with every probability of future increase, and a kind of occupation extremely congenial to his tastes and abilities. CHAP. VI.] 127 GENERAL POSITION. He had therefore no longer any need to continue the struggling endeavours to introduce novelties, and to force untried inventions into notice, which had occupied him for the last sixteen years, draining the pecuniary resources of himself and his friends, and keeping him in a constant state of worry and trouble. In writing to a confidential friend he expressed this clearly. said:- He A great change has come in me. Instead of persisting obsti- nately in my desire to realize a certain idea at the evident sacrifice of health and wealth, in order to throw it aside when it might begin to bear fruit, I wish now to strive to pursue a more prudent. course, caring a great deal more for the result, and less for the thankless task of accomplishing mere novelties. He accordingly came to the sensible resolution to devote his attention mainly to that kind of work which was likely to be profitable;—and not to jeopardise his position and his comfort by striving after ingenious new schemes. He was not, however, debarred from exercising his prolific inventive power. There were, as we shall see, abundant ways in which this could be brought into play consistently with his main designs. The change was, that either his inventions formed part of his general work, or if they were occasionally independent of it, they were such as he could now afford to indulge in without fear. One of his first steps was to consolidate his position among his professional brethren. In 1854 he had been elected an Associate of the Institution of Civil Engineers; but he now aspired to be transferred to the rank of full Member. This was a matter not without difficulty, inasmuch as Mr. Siemens was a contractor and manufacturer, and the 128 [CHAP. VI. ACTIVE BUSINESS. rules of the Institution excluded these classes from full membership, except in cases where the candidate could show very distinguished merit in the power and practice of engineering design. This exception was admitted to apply in Mr. Siemens's case. The recommendation for his transfer was signed by ten of the most distinguished men in the profession, and he was transferred to the grade of full Member of the Institution on the 11th December, 1860. His next care was to obtain a recognized standing in the scientific world, and he found little difficulty in this. His scientific work, while residing in London, had become so well known that a number of influential friends recom- mended him to the notice of the Council of the Royal Society. The following is a copy of the "Qualifications of the Candidate,” as stated in the formal certificate of recom- mendation to the Council:- CHARLES WILLIAM SIEMENS, Esq., 3, Great George Street, Westminster, Mem.

The recommendation was signed by the following Fellows of the Royal Society :- JOHN HAWKSHAW; J. F. BATEMAN; T. GRAHAM; G. B. AIRY; M. FARADAY; J. PERCY; A. W. WILLIAMSON; W. THOMSON; R. FITZROY; C. WHEATSTONE; J. P. GASSIOTT; J. FIELD; G. RENNIE; C. MANBY; T. WEBSTER; W. POLE; J. G. Appold; J. P. JOULE. He was selected by the Council as one of the fifteen candidates to be recommended to the Society; he was elected a Fellow on the 5th June, 1862, and was formally introduced at the Society's meeting on the 19th June. In 1859 he removed his office from John Street, Adelphi, to No. 3, Great George Street, Westminster, in order to be near the head-quarters of the engineering profession, and here he transacted jointly his own business and that of the telegraph firm. During the period over which this chapter extends he was almost exclusively engaged on the two great subjects, which indeed occupied him more than anything else for the remainder of his life;-namely, Heat and its Applica- tions, particularly to Metallurgy; and Electrical Science and Practice. He found time, however, to extend his writings on scientific and technical subjects, in which he afterwards showed great facility, and by which his name became more known in the mechanical and scientific world. These occupations will now be described more in detail. K 130 [CHAP. VI. ACTIVE BUSINESS. THE REGENERATIVE FURNACE. In the last chapter an account was given of the inven- tion of this furnace in 1856 by Frederick Siemens, and of its successful introduction into use by the joint labours of the two brothers. Experiments were carried on for some years, with a view to the perfecting of the apparatus, and its adaptation to a variety of uses;-and during these, the Messrs. Siemens saw clearly that a problem of great mag- nitude was opening up before them, by the novel and remarkable capabilities of the invention. It was soon found that the adaptation of the new regenerative apparatus to furnaces of ordinary kinds would effect considerable saving of fuel; but this turned out to be only a minor point of advantage. It gave a far more important effect in the production of greatly increased temperatures, and consequently much higher power. The action of the respirator absorbed and utilized the heat that formerly escaped into the air from the chimney; -this was the cause of the saving of fuel. But it did more. It brought the supply of air to the furnace, not at atmospheric temperature as before, but strongly heated, causing a most vivid combustion of the fuel; and when the heat of this was added to the already highly-heated entering air, a temperature was produced much beyond what had been previously obtained by any heat-producing apparatus on a large scale. It was clear, on this account, that the new furnace would give a widely extended range of effect in metallurgical operations and chemical processes generally. The experimental trials, therefore, were now largely devoted to the testing of this new power, and to the CHAP. VI.] THE REGENERATIVE FURNACE. 131 determination of how it might be most successfully and advantageously applied. The result showed an enor- mous capability of producing high temperatures; and the great difficulty became how to provide such materials, and to arrange such a construction of furnace, as should in practical use withstand the great heat produced. In fact most of the early failures consisted in the destruc- tion of the furnace itself, or of its accessories, in the attempts to apply the heat to the objects to be acted on. In the course of these trials a modification suggested itself to the two brothers, of such a character as to amount to a most important new invention. It was found that the use of solid fuel, in the body of the furnace, offered obstacles to the favourable working of the system, and the idea arose of substituting gaseous fuel, the solid fuel being converted into combustible gases in a separate construction called a "gas-producer." This was patented 22nd January, 1861, in the names of the two brothers jointly. The patent said :— It is an essential part of our invention that the solid fuel should be decomposed in a separate apparatus, so that the introduction of solid fuel into the furnace may be altogether avoided; and inde- pendently of the advantage that results from heating the gaseous fuel prior to its entering into combustion, there is a great advantage derived from the absence of any solid carbon or ashes in the working chamber of the furnace, by which we are enabled to carry on operations in the open furnace which it has only been possible hitherto to conduct in covered vessels or pots. The specification described various modifications of furnaces having "gas-generators" of this kind. The new invention was described by William Siemens in a second Paper read to the Institution of Mechanical K 2 132 [CHAP. VI. ACTIVE BUSINESS. Engineers on 30th January, 1862. After alluding to this original form of the furnace, he said :- In attempting, however, to apply the principle to puddling and other larger furnaces, serious practical difficulties arose, which for a considerable time frustrated all efforts; until by adopting the plan of volatilizing the solid fuel in the first instance, and employing it entirely in a gaseous form for heating purposes, practical results were at length attained surpassing even the most sanguine expectations previously formed. The fuel employed, which may be of a very inferior description, is separately converted into a crude gas, which being conducted to the furnace has its naturally low heating power greatly increased by being heated to nearly the high temperature of the furnace itself, undergoing at the same time certain chemical changes whereby the heat developed in its subsequent com- bustion is increased. The heating effect is still further augmented by the air necessary for combustion being also heated separately to the same high temperature. Elaborate and full descriptions of the improved furnace, as applied to different purposes, were given in the paper. This invention immensely improved the furnace, and made it applicable to much more extended processes, while its facility of management became much increased. The condition also of using an inferior fuel became a great advantage; for, in fact, combustible matters which would be utterly useless in an ordinary furnace were capable of being utilized without difficulty in the new gas-producer saw-dust, peat, lignite, soft coal or coal slack, might all be made available by simple modifications of the apparatus, so that large resources of fuel hitherto deemed waste material were brought into use and acquired commercial value. It was also remarkable that a new and unexpected source of fuel arose from the construction of the grate, namely the decomposition of water which, being kept underneath the bars, evaporated, and in passing CHAP. VI.] THE REGENERATIVE FURNACE. 133 as vapour through the fire became decomposed and furnished hydrogen in a combustible form. Another peculiarly valuable property of the new arrange- ment was the capability of exercising a large control over the quality of the heating agent, as immediately applied to the substance acted on. In the old form of furnace, the flame and heated currents from the fuel contained im- purities and foreign substances of many kinds which were often prejudicial to the quality of the article produced. In iron working, for example, the coal contained sulphur or phosphorus or silicon, which could not be prevented from damaging the material in the furnace; and in many chemical processes of a more refined nature, the impurities. in the solid fuel caused great inconveniences. But with the new gas fire, many impurities were left behind in the gas-producer, and the acting flame lost to a large extent its noxious power. In the more delicate chemical work, means were soon discovered of cleansing the gas, and rendering it a simple pure heating agent, by which the furnace operations were simplified and the manufactured article was improved. This was one of the qualifications which brought the furnace into such high repute for glass making. An experimental Gas Furnace had been built by Frede- rick Siemens at the works of Siemens and Halske in Berlin; and when the details had been satisfactorily arranged and the patent secured, others were constructed for actual use. The first of these was erected in 1861 at the flint glass works of Messrs. Lloyd and Summerfield, at Birmingham, and in 1867 it was stated by Mr. Siemens to be still at work, saving 50 per cent. of fuel. Another, built soon afterwards for glass works at Mexborough, in Yorkshire, worked equally well; and the success of the 134 [CHAP. VI. ACTIVE BUSINESS. invention became at once acknowledged in the glass trade.* Among the earliest users of the furnaces were the well- known large glass manufacturers, Messrs. Chance, near Birmingham, who had been induced to try them at the recommendation of Mr. Cowper. The success The success was so prompt and marked that they gradually increased the number to thirteen, in addition to a special one for optical lighthouse lenses, a manufacture requiring great care and perfection. It happened that in March, 1862, Professor Faraday, who was visiting Messrs. Chance's works on other business, saw some of these furnaces at work, and he was induced to make the following application to Mr. Siemens :— MY DEAR SIR,— ROYAL INSTITUTION OF GREAT BRITAIN, March 22, 1862. I have just returned from Birmingham, and there saw at Chance's works the application of your furnace to glass making. I was very much struck with the whole matter. As our managers want me to end the Friday evenings here, after Easter, I have looked about for a thought; for I have none in myself. I think I should like to speak of the effects I saw at Chance's if you do not object. If you assent, can you help me with any drawings or models or illustrations, either in the way of thoughts or experiments? * Mr. Cowper relates a curious incident illustrating the novelty of the great heat-production of these furnaces. The manager of a large glass works went to see one of them at work; but he would not believe that such an intense temperature could possibly be produced by such a small quantity of fuel as he saw burning, and with such a quiet steady draft. He fancied that the heat had been surreptitiously got up by more powerful means before he arrived. He expected it would soon cool down, and he waited through all the following night to see the diminution, and to expose the fraud. It was not till daylight came, and found the furnace continuing the same action, that he became convinced of the groundlessness of his suspicions, CHAP. VI.] THE REGENERATIVE FURNACE. 135 Do not say much about it out of doors as yet, for my mind is not settled in what way (if you assent) I shall present this subject. Ever truly yours, C. W. SIEMENS, Esq., &c., &c., &c. M. FARADAY. Mr. Siemens was much pleased with this flattering offer. He at once communicated with Faraday, and explained to him fully the whole construction, action, and capabilities of the invention. Faraday was even more interested in these explanations than he had been in the sight of the furnaces themselves, and they opened to him such new views of the matter that he consented, at Mr. Siemens's urgent request, to go again to Birmingham for the purpose of making further observations with Mr. Siemens's aid. He wrote again :- MY DEAR SIR,— ROYAL INSTITUTION OF GREAT BRITAIN, Wednesday, May 28, 1862. The moment I got upstairs I found that I could not go to Birmingham on Tuesday or Monday 10th or 9th. I am engaged to receive an LL.D. Degree at Cambridge on the occasion of the Installation of the Duke of Devonshire as the Chancellor of the University, and whether the day will be Monday or Tuesday is yet doubtful. But if Wednesday the 11th will suit you, I will go on that evening to Birmingham by the 6 P.M. train as we proposed. C. W. SIEMENS, Esq., &c., &c., &c. Ever truly yours, M. FARADAY. They accordingly went together, and Mr. Siemens often afterwards alluded to the two days spent with Faraday as among the happiest of his life. It was not only a great pleasure to him to have the opportunity of explaining his apparatus to such an appreciative observer, but he was, as 136 [CHAP. VI. ACTIVE BUSINESS. he said, perfectly enchanted with Faraday's manner, and struck with admiration of his character and attainments. The lecture undertaken by Faraday was given at the Royal Institution on the evening of the 20th June, 1862, the Duke of Northumberland, K.G., in the chair. He described the furnace with his usual lucidity, and the lecture is remarkable as having been the last ever delivered by that great philosopher. It is recorded in the Proceed- ings of the Royal Institution, Vol. III., page 537. The furnace was shown in the International Exhibition of 1862, together with the water meter and with the gas engine mentioned on page 154. A medal was awarded to Mr. Siemens for these, the special grounds being stated as the "Practical success of the furnace and water meter, and the originality of the whole." After this the Regenerative Gas Furnace became a great and undoubted practical success, and soon received numerous industrial applications. Before the end of 1862 about 100 of them were applied for various purposes in England and on the Continent. The early experiments had not been without trouble. Many real difficulties were encountered before the best construction and arrangements were arrived at; and even when the furnaces came more into use, failure often occurred when novel applications were made, or where unusual con- ditions had to be fulfilled, or where the management was unskilful or not in conformity with the inventor's direc- tions. But these failures differed essentially from those which Mr. Siemens had had to encounter with his previous heat inventions, inasmuch as they were clearly seen to be exceptional, and were altogether overborne by the general success, which was clear and undeniable. The saving of heat by the regenerative process rendered CHAP. VI.] THE REGENERATIVE FURNACE. 137 itself obvious by the reduced temperature of the current escaping into the atmosphere. With ordinary furnaces this heat was often so great that volumes of flame might be seen emitted at the top of the chimney. Indeed, as a fierce heat had to be maintained for the work to be done, there was no available means of preventing a large portion of the gases so heated from passing away. But with the regenerative furnace, although the heat inside might be above 4,000° Fahr., it was found that the gases escaping might be cooled down to between 200° and 300°, only just in fact what was sufficient to create a draft in the flues. At the London and North Western shops at Crewe, an ingenious plan was adopted of proving this. A piece of freshly cut wood was enclosed in the chimney flue, and kept there under lock and key for a certain number of days, and if, on being examined, it was found to be burnt, or even badly charred, the men who worked the furnace were fined for want of care and waste of fuel. The following extracts from some of Mr. Siemens's letters will show the results obtained. Speaking of one of the Glass Furnaces he said :— The saving of fuel is very clearly demonstrated by the circum- stance that an ordinary furnace of the same number of pots is worked by the side of it. The old furnace consumes fourteen cart loads of coal per week and the new furnace six. But the new furnace is so much better that it brings out a charge of glass in half the time. This gives a saving of more than three-fourths of the fuel; but an advantage of equal if not more importance is realised in the new furnace by the superior quality of glass obtained from a given mixture of materials. In another case he wrote: In general, where the furnaces work day and night, 50 per cent. 138 [CHAP. VI. ACTIVE BUSINESS. of fuel in weight is saved, and where expensive material, such as coke, has been heretofore employed, much larger saving has been effected by ordinary loose refuse coal (slack) being substituted. Then as to the intensity of the heat obtained, Mr. Siemens said:-- The greatest heat which can be produced by direct combustion of coke and air is about 4,000° Fahr. But with my regenerative furnace I should have no difficulty in going to 10,000°, in fact to any degree the material composing the furnace can be made to stand. The furnace melts the steel in pots very well ; the only dif- ficulty experienced consists in occasionally melting the pots also ! The furnace was discussed at the 1865 meeting of the British Association at Birmingham, on a paper by Mr. S. H. F. Cox, one of Mr. Siemens's assistants, when several eminent authorities, including Professor Miller (the eminent chemist), Mr. Bessemer, and Sir William Arm- strong, spoke strongly in its favour. In 1867, at the Exposition Universelle at Paris, one of the "Grands Prix" was awarded for the "Siemens Four à Gaz, à Chaleur Regénérée," chiefly on account of the perfect success of the furnaces in the leading glass works in France. As the advantages of the invention became more widely known in the industrial world, the demand for the furnaces went on constantly increasing year by year. Mr. Siemens's own energy was severely taxed in devising and arranging the various applications, a task involving constant personal interviews and enormous correspon- dence; and he had not only the aid of his brother Frederick, but a large office staff of skilled draughtsmen, and a CHAP. VI.] THE REGENERATIVE FURNACE. 139 travelling body of experienced assistants engaged in super- intending the erections and testing the working of the apparatus. In 1868, the demand had become so great that the office could not keep pace with them. The appli- cations had extended not only throughout the glass making trade, in which the invention had formed a marked epoch, but to various operations in iron and steel works, to the heating of gas retorts, to smelting and reducing ores and other metallurgical operations, to chemical manufactures, and in fact to all industrial processes where heating was required. All these had involved the construction of hundreds of furnaces, many of quite novel design, and some of unprecedented magnitude. This success brought Mr. Siemens a considerable acces- sion of income, for his share of the patent rights. The charges made were very moderate, being usually stipulated at one-eighth part of the saving effected; or sometimes £10 to £20 per annum for each furnace used. But as the manufacturers began to realize the benefits of the invention, they often commuted the payments into a lump sum. On the whole, the returns became very large, and increased continually. The results of experience during the quarter of a century that has elapsed since the introduction of this invention, have tended constantly to increase the estimation of its value, and to extend its use to a greater variety of purposes. Indeed, there is hardly an industrial process of any kind where great heat is required, that has not benefited by the application of the Siemens furnace, the advantages being not only an enormous economy of fuel, and the production of a much higher temperature, but also greatly increased facility of application and management, more perfect. combustion, and an entire absence of smoke, 140 [CHAP. VI. ACTIVE BUSINESS. In 1880, after nearly twenty years of continuous working and extended application, Sir Henry Bessemer, who could certainly speak with authority on the subject, described the furnace as at once the most philosophic in principle, the most powerful in action, and the most economical of all the contrivances for producing heat by the com- bustion of fuel. Puddling Iron. One of the purposes which Mr. Siemens had most earnestly in view for the regenerative furnace, was its application to the process of puddling, i.e., the formation of malleable iron from the pig or cast iron produced by smelting the ore. This object presented itself to him almost immediately after the furnace was brought out. In the middle of 1857 he had a furnace for this purpose. erected at the iron and steel works of Messrs. Rushton and Eckersley at Bolton in Lancashire. This was experi- mented on by himself, and he made offers to introduce the invention at some of the large ironworks in Staffordshire; but the results do not seem to have been encouraging. The subject was on his mind for many years afterwards, and he often renewed his proposals thereon to manu- facturers, insisting on the advantages they might gain thereby. In 1863 he included the "four à puddler,” in a formal licence to Messrs. Martin in France; and in 1864 he offered to the Mersey Steel and Iron Company to con- struct puddling furnaces for them at his own risk. It appears that some furnaces were erected in conse- quence of these proposals, but the results were doubtful, and Mr. Siemens turned back to his own former trials at Bolton, and resolved to carry them further. He was so satisfied with the promise of those trials, that CHAP. VI.] 141 THE PUDDLING FURNACE. in 1868 he described the furnace in a paper laid before the British Association. The Council of the Association were impressed with the importance of this paper, and they decided, unsolicited, to publish it in extenso in the Proceed- ings instead of in abstract as usual; an honour seldom granted. The paper was considered the best read at the meeting. After a careful scientific analysis of the chemistry of the puddling process, he said :- Led by these chemical considerations, and by practical attention to the subject, I am brought to the conclusion that the process of puddling, as practised at present, is extremely wasteful in iron and fuel, immensely laborious, and yielding a metal only imperfectly separated from its impurities. After describing the new furnace, he pointed out the advantages it had shown in economy of time, fuel, and labour, in facility of management, and in increase of quantity and improvement in quality of the metal pro- duced. He added, that the application was about to be tried by several enterprising iron firms, and this was afterwards done. In 1871, a committee was appointed by the Iron and Steel Institute, "to visit various works in which improved appliances or arrangements for puddling were in operation," and they laid their Report before the meeting in 1872. They mentioned several places where puddling furnaces on Siemens's plan were in use. In some cases the reports were favourable, but in others difficulties were met with; and on the whole the application of the regenerative furnace to this purpose does not appear to have come into use to any important extent. 1 142 [CHAP. VI. ACTIVE BUSINESS. STEEL MANUFACTURE. A far more important and successful use of the furnace was, however, brought into operation by Mr. Siemens during the period comprised in this chapter; namely, its application to the production of steel; and as this proved to be one of the most important of his life's labours, it deserves a somewhat full notice here. The ordinary method of steel making by the process. called cementation, i.e., by the prolonged heating of bar iron in contact with charcoal, was tedious and expen- sive. Other modes had been partially used; but it was not till the introduction of the Bessemer process, between 1856 and 1860, that the metal could be produced on a large scale and at a cheap rate. This process, how- ever, required a peculiar and cumbersome apparatus, and a desire was naturally felt for simpler means of accomplish- ing the same end. Such a means had been suggested as early as 1722 by Réaumur, the distinguished French philosopher, who pro- posed to produce steel in large quantities by simply fusing wrought and cast iron together on the open hearth of a reverberatory furnace. This proposal was afterwards. renewed by a well-known practical steel maker, Heath, of Sheffield. The experiment had been tried, but it had not succeeded in consequence of the defects and want of power in the furnace employed. Mr. Siemens saw that with his regene- rative furnace it might be possible to carry out this idea; and accordingly, soon after the earliest patent was ob- tained, Frederick and William Siemens made some trials with this view. But they were very imperfect, and it was CHAP. VI.] THE STEEL MANUFACTURE. 143 not till the great improvement was effected by gaseous fuel in 1861, that there was any real hope for the steel manufacture. The advantages of the improvement, for this purpose, consisted not only in the increased power, but also in the exclusion of solid fuel, which rendered it possible to secure a degree of purity in the melted product, which, with ordinary reverberatory furnaces, was quite unattainable. This application of the Gas Furnace to steel making was clearly in the minds of the brothers Siemens when it was first brought out by them, as is shown by the following passage in the original patent of January, 1861 :- We are enabled to carry on operations in the open furnace which it has only been possible hitherto to conduct in covered vessels or pots. We are thus enabled to melt flint and other superior qualities of glass in open pots, to fire pottery without enclosing the same in saggers, or to melt steel and other substances upon an open hearth or bed without injury. In a subsequent part of the patent a construction of furnace is described, which it is said— May be employed with advantage for smelting iron, for making steel, or roasting copper and other ores. In attempting to carry the idea out, great difficulties had to be encountered. The question arose whether steel could be melted and maintained as steel upon the open hearth of a furnace, at a temperature exceeding the melting point of most fire bricks. The general opinion of practical men was entirely opposed to the idea; and its realization required both time and patience. During the year 1861 Mr. Siemens brought the subject before Mr. Abraham Darby, of Ebbw Vale, in South Wales; 144 [CHAP. VI. ACTIVE BUSINESS. and some experiments were tried by the two brothers, with the aid of some manufacturers, at the great steel making locality, Sheffield. But they failed, partly on account of defects in the early furnaces, and also, in a great measure, from the want of perseverance on the part of the manu- facturers and their workmen. The earliest successful use of the Siemens furnace for steel purposes appears to have been, not for the original produc- tion of the metal, but simply for the melting of it in large quantities. It may be explained that one of the most important operations in the steel manufacture consists in subjecting the material to the process of melting in pots, so producing what is called cast steel. Pieces of steel, already converted by cementation or other carburetting process, are melted in crucibles or pots, exposed to a high heat in a furnace, certain ingredients being sometimes added to affect the chemical composition. The result of this melting is greatly to improve the quality, producing the most valuable form of steel. But the quantity of steel that can be melted in each pot is necessarily limited; the manipulation is troublesome; and the whole process is expensive. One of the first questions therefore was whether, by this Siemens furnace, the melting of steel could be effected without the use of crucibles. In 1862 Mr. Siemens had some correspondence with Mr. Charles Attwood, of the Tow Law Iron Works, near Durham, on this subject, and made for him a design for a furnace, sufficient to melt 5 cwt. of steel on the open hearth. There is no record of the details of Mr. Attwood's trials, but the result was that although the furnace fully answered its purpose, he did not succeed in getting the quality of steel he desired, and the manufacture was not continued. CHAP. VI.] THE STEEL MANUFACTURE. 145 In the meantime a friend of Mr. Siemens, an eminent French metallurgist, M. Lechatelier, had been interesting himself to get the furnaces used abroad, and Mr. Siemens had granted, at his instance, a license to the "Société Boigues Rambourg & Cie.," of Fourchambault, to use the heating system in conjunction with some process designed by M. Lechatelier. A furnace was erected and some samples of steel were obtained, but the roof of the furnace soon melted down, and the proprietors were so disheartened that they abandoned the trials. The subject was taken up with more success by another firm, Messrs. Pierre and Émile Martin, steel and iron manufacturers, at Sireuil in the Department of the Charente. A correspondence was opened between them and Mr. Siemens which led to the agreement set forth in the following letter: LONDRES, 26 Mars, 1863. À MONSIEUR ÉMILE MARTIN, 12, Rue Chaptal à Paris,— Me référant à la conversation que j'ai dernièrement eu l'avantage d'avoir avec vous à Paris, il est entendu que vous êtes autorisé d'appliquer mes procédés de chauffage à vos fours à puddler, à rechauffer, à souder, et à fondre l'acier sur un sol ouvert dans vos forges de Sireuil.

ACTIVE BUSINESS. constructions et la mise en marche de vos nouveaux fours, je mettrai une personne capable à votre disposition, ses frais de voyage aller et retour, ainsi que ses appointements à raison de 20 francs par jour, demeurant à votre charge. C. W. SIEMENS. Messrs. Martin acted on this privilege by getting a fur- nace constructed under Mr. Siemens's direction. But they did not confine its use simply to melting steel already made, they adapted it for effecting the production of the metal, by the process suggested by Réaumur and Heath, namely, by fusing cast and wrought iron together. They succeeded in producing, by this method, cast steel of excellent quality and of various tempers; they received a new and extended licence from Mr. Siemens in 1866, and their produce, as farther carried out and improved, was awarded a gold medal at the French Exhibition of 1867. In 1865 further experimental trials were made, at Mr. Siemens's instance, at Barrow, and other places in England and Scotland. They were successful in producing good steel, but difficulties were found to arise, chiefly from the action of the great heat on the structure of the furnace, and the manufacture was not profitable. Mr. Siemens however held to the opinion that the process would, if perfected, be of great value, both scientifically and commercially; and despairing of seeing it successfully carried out by manufacturers, he determined to change his plan of operations. Hitherto he had done nothing beyond supplying the furnaces, leaving the steel making and melting operations entirely to the manufac- turer. But he resolved now to undertake some extensive experiments on steel making under his own eye, for the purpose of thoroughly investigating the question. CHAP. VI.] 147 THE STEEŁ MANUFACTURE. In 1865 a favourable opportunity of doing this occurred. It happened that a furnace erected some time before on his principle at No. 20, Hampton Street, Birmingham, had become disused; and the premises where it stood were offered to Mr. Siemens. He saw this would be a conve- nient place for his steel experiments, and it was accordingly arranged that he should rent the premises for a year, with liberty to alter and use the furnace as he desired. Possession was obtained the beginning of 1866, and on the 29th March he wrote to Mr. Attwood:- The steel furnace at Birmingham is alight, and appears to do well. The first charge will be melted on Saturday. In August he said :- The steel melting furnace which I erected at Birmingham has now been in full operation for some time, and is a most complete success. It has been working night and day for five weeks in melting extra soft steel for wire, and the furnace lining is still intact. The body of the furnace will last for several years, and the lining when it fails can be replaced in a day. The consumption of fuel does not exceed 1 tons of slack per ton of cast-steel of the softest kind produced. . . . I can produce a ton of cast-steel for less money than Bessemer, and of superior quality. The experiments went on unremittingly, and were so useful, and the results so important, that Mr. Siemens found it worth his while to take a lease of the premises for fourteen years. He did not wish at that time to be considered a steel manufacturer, or to interfere with the trade, as he preferred to work in co-operation with the steel firms. He arranged that they should commission him to manufacture steel for them, supplying him with the materials, and sometimes also with the labour, but he directing the whole details of manufacture. In fact, what L 2 148 [CHAP. VI. ACTIVE BUSINESS. he wanted was that the makers should see for themselves what it was possible to accomplish, if his process was carried out thoroughly and effectually. As, however, his operations became larger, it was difficult to avoid executing orders for steel that were sent him, and towards the end of 1867 he resolved to extend the works and add new furnaces, so as to enable him to keep a stock of materials, and, to a small extent, manu- facture steel for sale. He still, however, desired to avoid. the appearance of competing with the steel trade, and for this purpose he determined to give a name to his works which should indicate the limited purpose he had originally in view in regard to them. He at first thought of the term "Model Steel Works;" but afterwards considering that this would imply conditions of perfection that were not to be attained in such a position, he altered the name to "The Siemens Sample Steel Works," by which title they were afterwards generally known. The work was at first carried on under great dis- advantages; the processes were new, and Mr. Siemens. had to educate his own workmen; but by perseverance the difficulties were overcome, and the results of the experiment were most beneficial in enabling him, not only to work out successfully the details of the various processes, but to exhibit and prove their advantages to manufacturers in the trade. He succeeded perfectly in obtaining a full command over the qualities of steel manufactured, and samples made at the works obtained, like Messrs. Martin's, one of the great prizes at the Paris Exhibition of 1867. He now took out his first patent specially for the steel manufacture. It was dated 21st August, 1867, and entitled "Improvements in Furnaces and in Processes and Apparatus CHAP. VI.] 149 THE STEEL MANUFACTURE. in connection therewith, principally applicable to Metal- lurgical Operations." It commenced by stating :— Cast-steel may be produced directly from the ore. Or it may be produced by melting cast-iron (containing by pre- ference manganese) and scrap-iron, or scrap-steel, or blooms of puddled steel or iron in a reverberatory furnace,— Or it may be produced by these two processes conjointly. The improved arrangements of furnaces for these purposes were described, and the claims bearing on them were as follows: Second.-Making cast-steel upon the open hearth of a furnace by causing wrought-iron, steel, or white cast-iron to descend upon inclined planes or through hoppers, where they become gradually heated, into a fluid bath of cast-iron under the influence of very intense heat, where they are dissolved and converted into cast steel. Third.-Applying regenerative gas furnaces to the operations set forth... in such a manner that a portion of the products of combustion are withdrawn to heat the materials descending into the furnace by gravity, while the remaining products of combustion, which have not been reduced in temperature by contact with cold materials, pass through regenerators to the chimney in the usual manner, the effect being that the temperature of the furnace is not reduced by the introduction of such cold materials. In May, 1868, Mr. Siemens explained his invention in a lecture given to the Chemical Society of London ;—and it may be convenient here to give a brief description of the processes used by him. The basis in all cases is the use of pig-iron, which is melted so as to form a "bath" in the furnace. But this contains a superfluity of carbon, and in order to reduce the quantity of this to the small proportion necessary to form steel, the liquid mass has to be partially decar- buretted by treatment with some other substance, and this decarburization may be done in two different ways. 150 [CHAP. VI. ACTIVE BUSINESS. First, it may be effected by adding malleable iron, usually in the shape of what is called "scrap." A bath, of say 30 cwt. of highly heated pig metal is provided on the furnace hearth, into which from 4 to 5 tons of scrap metal or puddled bars are gradually introduced in a heated con- dition. They readily melt and mix with the pig metal, and the addition is continued until a point is reached when the carbon of the combined fluid mass does not exceed 0.1 per cent., a point which can be readily ascertained by testing a sample taken from the bath. Ferro-manganese or Spiegeleisen is then added in such quantity as will impart the requisite proportion of carbon and manganese to form the quality of steel required. This process was named by Mr. Siemens the "scrap scrap" or "Siemens-Martin" process, from the fact that Messrs. Martin had been instrumental to its first introduction by the aid of the Siemens Regenerative Gas Furnace. Secondly, it may be effected by adding iron ore. A bath of from 6 to 7 tons of molten pig metal is prepared, and ore (previously melted by preference with such a proportion of fluxing material as is necessary to form with the earthy matter of the ore and the silicon contained in the pig metal, a basic slag), is gradually introduced until, by the reaction of the ferric-oxide with the carbon and silicon of the bath, the latter substances are consumed, and a fluid bath of almost pure iron is obtained, when the operation is stopped, and Spiegeleisen added as before. This is called the "Siemens" or "Ore" process, and it is considered to have the advantage, that there is greater certainty as to the result, because of the known composition of the materials used, which cannot be the case in dealing with large quantities of scrap, obtained, probably, from many different sources. One of the advantages claimed for the open hearth pro- CHAP. VI.] 151 THE STEEL MANUFACTURE. cess, on either modification, consists in its not being dependent on a limited time for its results. The heat of the furnace is such that the fluid bath of metal, after being reduced to the lowest point of carburization, may be main- tained in that condition for any reasonable length of time. During this time samples can be taken and tested, and additions either of pig metal, of wrought scrap, or ore, may be made to it to adjust it to the desired temper. The proportion of Spiegeleisen or ferro-manganese, exactly requisite, is then added, and the result is a bath of metal the precise chemical condition of which is accurately known. This circumstance renders the material applicable for certain purposes for which pot-steel has hitherto been mostly employed.* Having established the efficacy and settled the details of his processes, Mr. Siemens determined to take steps to introduce them into beneficial use: and his first attempt was in the shape of an application to the London and North Western Railway Company. It occurred to him that his inventions might be advantageously applied to an object which would at once commend itself to the Railway Directors, namely the utilizing of their old worn out iron rails by converting them, with slight expense, into new ones of the superior metal, steel. The great advantage of steel over iron rails, in point of durability, was then just becoming appreciated, but the cost of new steel rails was high, and Mr. Siemens saw that by offering the companies the means of making them themselves at a cheap rate, he would be laying before them a tempting proposal. He therefore wrote as follows to Mr. Ramsbottom, the * Address to the Iron and Steel Institute, 1877. 152 [CHAP. VI. ACTIVE BUSINESS. engineer in charge of the London and North Western Railway Works at Crewe. The subject upon which I particularly wanted to see you is one of considerable importance, and having finished my plans and ex- periments, I think it will save you time and trouble if I put a distinct proposition before you, and through you before your Company. I have now fully succeeded to melt steel in from two to four ton-charges upon the open hearth of my Regenerative Gas Furnace. The quality of the steel produced is equal to pot-metal produced from the same materials, and the operation is conducted with the greatest ease. The cost of melting a ton of scrap-metal and its proportion (of 10 per cent.) of pig metal does not exceed 30s. per ton including fuel, labour, wear and tear of furnace and the ferro-manganese required. The cost of four furnaces and producers capable of producing easily 5000 tons of cast-steel per annum, would not exceed £3000. You would probably not require so great a number of furnaces for melting your scrap-steel, but iron is equally applicable, and it has struck me that your Company would have a great interest in converting old rails into steel of sufficient quality to make good steel rails. The old rails would have to be cut into lengths of three feet, and the weight of steel ingots produced would equal that of rails and pig metal put together, there being no waste in the process beyond what would be made up by the ferro- manganese. I shall be able to give you the means of trying this process at my own steel works at Birmingham in a furnace which will take 16 cwt. charges. On The Directors carefully considered the matter, and after some delay determined to make the experiment. the 4th June, 1868, Mr. Siemens, at their request sent in a more formal proposition; this was accepted, and some fur- naces were built under his direction. They fully answered their purpose, and the conversion of old rails into new ones by their aid has gone on to the present day. CHAP. VI.] 153 THE STEEL MANUFACTURE. In 1868 a somewhat similar application was made to the Great Western Railway, but in a different manner. Mr. Siemens obtained a truck load of their old rails from Swansea. He took them to his works at Birmingham, and converted them into steel ingots, which were sent to the rolling mills of Sir John Brown & Co. at Sheffield, to be rolled into new rails of the Great Western pattern. These were then delivered to the company, and were found by them to be of such remarkably good quality as to establish fully the value of the process.* The result of these applications was that in the year 1868 Mr. Siemens had under hand the construction of several furnaces for the carrying out of his modes of making steel. It would have been well if he had stopped here, and allowed the development of the new invention to take place among the manufacturers, contenting himself, as in the case of the Regenerative Furnace, with the highly profitable patent royalties that must have accrued to him. But he now wished to go further. The success of the trials at the Sample Steel Works, the general interest shewn in the new processes, and the prospect of supplying a valuable and high class material in constantly increasing demand, at prices realizing great profits, tempted him to do what he had formerly set his face against, i.e., to enter into trade as a steel manufacturer on a large scale. Towards the end of 1867, Mr. Siemens and a few friends proposed to form a private company to establish steel works in accordance with the new process. The locality first suggested was either on the Thames or in the North of England: but on further consideration the * These rails, though subject to more than ordinary traffic, were not taken up till 1878, and then were not worn out. 154 [CHAP. VI. ACTIVE BUSINESS. • district of South Wales was preferred. Search was made in this neighbourhood, and attention was directed to certain works at Landore, near Swansea, the property of Mr. L. L. Dillwyn, M.P., where Mr. Siemens had erected furnaces a few years before. In July he visited the neighbourhood, and other sites were considered, but on the 6th August, 1868, he wrote to one of the promoters :- It is really the utmost time to move, and I am quite satisfied to adhere to Landore and get to work. I have commenced setting out the works upon your plan, and hope to see you very soon, or we shall lose the whole year. An arrangement was accordingly made, and a small company was formed, under the name of the Landore Siemens Steel Company, Mr. Dillwyn being the Chairman, and Mr. Donald Gordon (Mr. Siemens's brother-in-law) the Managing Director. The works were purchased, and the alterations to fit them for their new purpose were made with all possible speed. They were set to work about the middle of 1869, when 75 tons of steel per week were produced of excellent quality. MISCELLANEOUS MATTERS. Regenerative Gas Engine. In 1860, Mr. Siemens designed an engine to be worked by gas, under a patent taken out by him in August of the previous year. It was driven by a combination of coal gas and air, the mixture being fired at each stroke by an electric spark. It was provided with a regenerative apparatus for saving a great part of the heat which would otherwise be discharged with the waste gases. An engine on this plan was actually constructed; it was shown at the International Exhibition of 1862, and is now CHAP. VI.] 155 MISCELLANEOUS MATTERS. in the Museum at South Kensington. It was mentioned by Dr. Siemens in a discussion at the Institution of Civil Engineers, 4 April, 1882. He said that the gas engine of the present day was, in his opinion, in the condition of the steam engine at the time of Newcomen. His own engine had promised to give very good results; but at the time of its invention he was too much occupied with other matters to attend to it. The time, however, was come when the subject required full investigation, as it was one of great importance to engineers. Gunnery Inventions.—Mr. Siemens gave some attention to the engineering implements of war. In 1861 he designed, and obtained a provisional patent for a peculiar kind of war-ship, intended to throw a large shell which he expected would "make an irreparable breach in an enemy's ship's side." He explained his invention to the Admiralty, but nothing came of the communication. In 1867, he was asked to give his advice in regard to checking the recoil in gun carriages, and he recommended hydraulic compression. This was afterwards adopted, without, as Mr. Siemens complained, any acknowledgment of his services in the matter.* Birmingham Gas Consumers' Company.-After the "gas producer” had been well tested in its application to heating furnaces, Mr. Siemens conceived the idea that he could adapt it to supplant the usual modes of manufacturing gas for illumination. In the year 1863, he induced some of his friends in Birmingham to take up the idea, and to get up a company for supplying gas so made to that town. He pre- pared designs for a gas producer, which, as he stated, would generate gas of the highest power, both for lighting and * Journal of the Iron and Steel Institute, 1881, vol. i., p. 489. 156 [CHAP. VI. ACTIVE BUSINESS. heating purposes; he laid great stress on the latter kind, which he said could be supplied for sixpence per 1000 feet. It would also produce coke very superior in quality to that ordinarily made in gas works. The company was to be called the Birmingham Gas Consumers' Company. A bill for the purpose of establishing it was presented to Parlia- ment in the spring of 1864, but it was rejected by the Committee appointed to examine it, and the proposition was never renewed. Governor.-During this period he revived the subject of his old chronometric governor, which always seems to have had a special attraction for him. On the 25th January, 1866, he read a second paper upon it before the Institution of Mechanical Engineers. After referring to the former description of his invention, and stating that it had acted at Greenwich with almost mathe- matical precision, he described an improved form of the machine lately introduced by him. The general idea, i.e., regulating the motion by com- parison with a chronometric action, was unchanged, but instead of the former pendulum apparatus he had now substituted a revolving cup containing fluid, the centrifugal action of which furnished the regulating element. He explained the applicability of the apparatus to clocks as well as steam engines, and concluded by saying :— The writer's practical career having commenced twenty-three years ago with the subject of the chronometric governor, although his attention has since been engrossed with other subjects, he trusts that this application of a new principle of action may lead to a more complete realization of the object in view, namely, the attainment of really uniform rotation in mechanism. But he had a higher view in regard to this invention than the mere practical regulation of steam engines. He CHAP. VI.] 157 MISCELLANEOUS MATTERS. looked upon the subject of "uniform rotation" as one of general scientific interest, and he accordingly presented a paper with that title to the Royal Society; it was read there on the 12th of April, 1866, and subsequently received the honour of being printed in the Philosophical Trans- actions. The improvement here described, was protected by a patent dated May 2, 1865: but we do not find that the invention had any important practical success; it was, how- ever, in later days, put to a use not originally intended. It had been remarked, that in regulating the speed of an engine, the machine acted to some extent as an absorber of surplus power, and this suggested the idea of applying it as a substitute for the treadmill or crank, in forced prison- labour. It was thus used in the gaols of Liverpool, Manchester, Leicester, Stafford, and elsewhere, giving every satisfaction. British Association.-During this period, Mr. Siemens took an active part in the proceedings of the British Association for the Advancement of Science. A body of this nature naturally presented great attraction for him. He had joined it in 1856, and had attended many of its meetings, communicating papers, and joining in the discussions. In the year 1869, at the meeting at Exeter, he was appointed President of Section G., Mechanical Science, on which occasion he delivered to the section an effective and appropriate opening address. This was not, as many such addresses are, a mere account of progress made and works effected, in mechanical science; but it discussed several interesting and relevant topics in a way showing much thought and originality. Among the subjects treated of were technical education; the Patent Laws; the application of heat; and the impor- 158 [CHAP. VI. ACTIVE BUSINESS. tance and utility of cooling processes, which have in later times been so largely developed. ELECTRICAL WORK. We must now turn to the other great branch of work that occupied Mr. Siemens, namely, electrical matters. While he appeared to be absorbed in the multifarious chemical, mechanical, and metallurgical details attendant on his gigantic furnace operations, he was also steadily and quietly persevering in his electrical business, which indeed now began to assume greater importance. At the end of the period comprised in the last chapter, ¿.e., in 1859, Mr. Siemens's position was that of managing partner of the English branch of the firm of Siemens and Halske, having a small manufactory of telegraph apparatus under his own care in London. They were already supply- ing telegraph work to a considerable extent, and Mr. Siemens had established a character for special acquaint- ance with the subject of submarine cables. Malta and Alexandria Cable.-In 1860 the firm were appointed by H.M. Government to superintend the en- gineering and electrical departments in the manufacture and laying of a cable which was originally intended to con- nect Falmouth and Gibraltar, and for which Messrs. Glass Elliott & Co. were the contractors. The destination of this cable was afterwards changed, when it was determined to lay it between Rangoon and Singapore, and for this purpose it was shipped at the end of the year on board the Queen Victoria. The vessel, however, encountered severe weather in the Channel and had to put into Plymouth for repairs, after which it was found impossible for her to reach the Malay coast in time for the fine season, and the project was therefore abandoned. CHAP. VI.] 159 ELECTRICAL WORK. In January, 1861, it was finally decided that the cable should be laid between Malta and Alexandria, and the scheme was successfully carried out in the following summer. The cable was divided into three sections, between Malta and Tripoli; Tripoli and Benghazi, and Benghazi and Alexandria respectively, the total length being about 1350 miles. The cable was laid by Government, Messrs. Siemens being engaged by them to act as electricians during the operation. Indiarubber as an Insulator.-The two brothers, Werner and William, having by this time had considerable ex- perience in regard to submarine cables, determined to make known some of the results they had arrived at, and in 1860 they wrote a joint paper to the British Association, embodying their studies of the Principles and Practice involved in dealing with the electric conditions of Submarine Electric Telegraphs. This paper had reference principally to the insulation, and to the use of indiarubber as an insulating material. An ingenious machine was devised by them for applying this to cables, and it was fully described by Wm. Siemens in a paper given to the Institution of Mechanical Engineers on the 8th August, 1860. Other published Papers.-Mr. Siemens had other ex- periences with the same cable, which he thought worth making known. In May, 1862, he gave to the Insti- tution of Civil Engineers an elaborate paper "On the Electrical Tests employed during the construction of the Malta and Alexandria Telegraph, and on Insulating and Protecting Submarine Cables." He had introduced new methods of testing, which he considered had given to this 160 [CHAP. VI ACTIVE BUSINESS. long cable a great superiority over all former ones in per- manency and in transmitting power;-and he gave full particulars of these methods and their results. In the course of these trials he had been led to study the con- struction of submarine cables generally, and he added notes of opinions which he had arrived at, particularly regarding their protection and insulation. This paper was rewarded by a Premium. He had further taken advantage of the manufacture of this cable to institute some experiments on the general electrical conditions of submarine cables, which he commu- nicated to the British Association at their Meeting at Newcastle-on-Tyne in 1863. Exhibition of 1862.-The firm of Siemens and Halske sent to this Exhibition a very large assortment of electrical apparatus of various kinds, appearing both as British and as foreign exhibitors. The collection attracted great notice, and was rewarded by three separate Medals, namely:- One for "the general excellence of their telegraphic apparatus ;"— One for "a well-constructed telegraph wire-covering machine" for coating with indiarubber. And one for "their mechanical transmitter for Morse's telegraph, and for their voltaic induction coil, the most powerful exhibited.” While the exhibition was going on Mr. Siemens wrote, for the Practical Mechanic's Journal, a general description of the electrical instruments and telegraphic apparatus shown therein. This article, prefaced by a history of the electric telegraph, and profusely illustrated by engravings, was so full and elaborate as to form a complete record of electric telegraphy as it existed at that time. CHAP. VI.] 161 THE ATLANTIC CABLE. The Atlantic Cable.-After the failure of the first cable laid across the Atlantic in 1858, the Board of Trade ap- pointed a Commission, consisting of Captain (now Sir Dou- glas) Galton, R.E., Professor Wheatstone, Mr. (afterwards Sir) William Fairbairn, and Mr. G. P. Bidder, to join with the officers of the Atlantic Telegraph Company in holding an enquiry into the "best form for the composition and outer covering of submarine telegraph cables." This joint Com- mittee sat for nearly two years, and they took a great amount of evidence from persons of experience on the subject. Among these was Mr. Siemens, who gave evidence. twice, namely, on the 1st December, 1859, and on the 9th March, 1860. He stated fully the results of his experiences with submarine cables ;-described experi- ments and observations he had made;—and gave at con- siderable length his ideas as to how a deep-sea cable should be constructed;-adding that he saw no reason why a cable lying 2,000 fathoms deep should not last as long as in shallower water. He also contributed an additional Paper, by himself and his brother, giving elaborate calculations and observations on electrical resistance and induction, with various materials. The Commission, in April, 1861, laid before Government a full Report, which, with the evidence and many valuable documents, was published as a Parliamentary Paper. Although Mr. Siemens's share in the matter of this first Atlantic enterprise was not very prominent, the study he gave to the subject was not lost upon him, for when, some ten years later, his firm undertook to lay additional cables across the Atlantic, he was able to make good use of the knowledge he had thus acquired. The Charlton Factory.-In 1863 a great change was effected in regard to the electric work. M 162 [CHAP. VI. ACTIVE BUSINESS. A few years' experience with the small Millbank work- shop had enabled the firm to see that, in view of the con- tinually increasing orders, an extension of the manufac- turing capabilities of electrical apparatus in England would be very desirable. Moreover, after the experience they had had in advising on and superintending the submarine work of other firms, they believed it would be to their advantage to undertake this branch of the business themselves. The Berlin firm had by this time increased greatly in magnitude. They had not only much extended their own business, but they had thrown out large branch establish- ments of a similar kind in St. Petersburg, in Vienna, and elsewhere; and they were not averse to bring up their London works to a like scale of importance. William was charged with the duty of arranging this. He found a piece of land of suitable character adjoining the Thames at Charlton, near Woolwich, where, with the concurrence and aid of the Berlin firm, he designed and erected manufacturing works of the kind desired, suitable for making all kinds of telegraph instruments, apparatus, and materials, including submarine cables, which could be thus shipped for transport directly upon the river. Thus originated the electrical manufacturing works which have since become so celebrated and so well known. At the close of 1864, Mr. Halske retired from his con- nexion with the London firm, which was then reconstituted, the three brothers, viz., Dr. Werner Siemens, of Berlin, Mr. Charles William Siemens, of London, and Mr. Carl Siemens, of St. Petersburg, being in partnership, and carry- ing on the business, from the beginning of 1865, under the name of "Siemens Brothers." The Berlin firm retained the name of Siemens and Halske. These works were gradually enlarged as the business increased, and as the applications of electricity became CHAP. VI.] 163 THE CHARLTON FACTORY. more extended to other objects, such as lighting, power- giving, and so on. They now occupy an area of above six acres; they have sometimes employed between 2,000 and 3,000 men, and have been capable of turning out 60 miles of submarine cable per diem. It need hardly be said that, although the three brothers had joint interest in the works, yet William, as the resi- dent partner and manager, had the chief responsibility in their management, and the most active share in the opera- tions. He gave unremitting personal attention to the works, and the result was that the multifarious processes there carried on, and the great variety of apparatus that issued therefrom, bore largely the impress of his originality and inventive power. It was a saying common in the work- shops, that as soon as any particular problem had been given up by everybody else, it had only to be taken to Mr. William Siemens for him to suggest half a dozen ways of solving it, two of which would be complicated and impracticable, two difficult, and two perfectly satisfactory. He had, to aid him, an efficient engineering and electric staff, at the head of whom was Mr. L. Loeffler, who had formerly been engaged in the Berlin firm, and who, at a subsequent period, became the managing director of the establishment. It would be tedious and unnecessary, in this work, to give any lengthy reference to the many works executed at the Charlton Factory. Our notices must be confined to those which were of special interest, or in which the part taken by William Siemens was specially deserving of mention. M 2 164 [CHAP. VI. ACTIVE BUSINESS. The Algerian Cable. The first work of importance undertaken in the new factory was a contract with the French Government for the manufacture and laying of a submarine cable to form a communication with their colonies in Algeria. It was to be about 140 miles long, extending from Oran, a town on the Algerian coast, to Carthagena in Spain, from whence land communications already existed with France. In January, and again in May, 1863, Mr. Siemens went to Paris to negotiate the matter. This was the first time the firm had undertaken to lay, on their own responsibility, a deep-sea cable, and on the 13th May Werner wrote to William as follows:- I hope this will find you in Paris. We shall be glad if you bring about this first contract for cable- laying. Although the depths, as far as I know, are considerable, I do not consider the laying itself very risky. I do not think we could, in case of need, get the whole up again, for raising a cable has always its difficulties, yet the risk is endurable, if we cannot get better terms; a more real difficulty consists in the uncertainty as to the means and conditions we may find there. The contract was duly obtained, and the new factory at Charlton being ready, the manufacture of the cable was at once put in hand there. The design of this cable was on a somewhat novel plan, so far as the outer covering was concerned, which consisted of a binding sheathing of thin brass or copper strips, overlapping each other and put on the hemp covering under great pressure. It was described in a paper to the British Association in 1865. The construction of the cable took longer time than was anticipated; but Mr. Siemens worked day and night at the factory to get it finished, and it was embarked on the 10th of December, 1863, on board a French ship specially CHAP. VI.] 155 THE ALGERIAN CABLE. fitted for the purpose, and which was afterwards named the Dix Décembre in honour of the day. It had been arranged that Werner and William should both go out to superintend personally the laying of the cable, and they left London for the purpose, accompanied by Mrs. William Siemens, on the 19th December, passing through Paris and Madrid. On January 1st, 1864, the Diary of Mrs. Siemens says: "A new year in a new country. 'Auf nach Valencia,' and here we are in Valencia; Werner, William, and I, drinking the healths of our dear ones in Germany and Old England.” From thence they travelled by land through Almanza, Alicante, and Murcia, to Carthagena, where they joined the ship that carried the cable. It had been decided to begin the laying from the Oran end, and on January 9th the ship left Carthagena, arriving at Mers-el-Kebir, near Oran, the following morning. The necessary preparations having been made, and the "shore end" having been laid, on the 14th January the Dix Décembre was brought up to the spot, and having connected the cable end, the laying commenced at I P.M. All appeared to go well for some hours, when the cable broke. After the fracture the ship returned to Mers-el-Kebir. A consultation was held on board, and the question was raised whether it would be possible to lay the remainder of the cable, still lying in the vessel, between Oran and another town in the South of Spain, Almeria, a distance much shorter than to Carthagena. To further this enquiry the ship sailed on the 15th for Almeria; some soundings were taken, and she returned on the 19th, having passed through a fearful storm. More consultations followed, and it was at last decided to try the Almeria line. On the 28th another connexion was made to the shore end, 166 [CHAP. IV. ACTIVE BUSINESS... and at 6 A.M. the laying was begun, but about 7 P.M. the cable again broke, and the following day the ship returned to Carthagena. Mr. Siemens and his party then proceeded to Madrid, and afterwards to Paris; he remained a long time in treating with the Government as to future pro- ceedings; and he did not get home till nearly the end of February. On this journey, as well as on many subsequent ones, it was a great comfort and assistance to William to have the companionship of his wife. In one letter to her sister she wrote:- With such a husband, surely I can brave all things, and being ever at his side I make him careful of himself, and now and then turn even this into a pleasure trip! . But those who have travelled in Spain some twenty years ago in the depth of winter, may form an idea how much a delicate lady would have to "brave" in such a journey. It was not only the intense cold, for the alleviation of which there was no provision, but there were many other discomforts of many kinds; and in the six weeks during which she had to endure these trials her health suffered materially. The French Government had authorized Mr. Siemens to carry out his proposal for a second attempt, and he forth- with put in hand the manufacture of the new quantity of cable required. This was ready in a few months, and about the beginning of August, 1864, William left England for Toulon, from whence he proceeded on board a French Government steamer to Algeria. On this journey he would not allow his wife to accompany him. On the 12th September she received a telegram telling her that the cable was successfully laid; but on the 17th followed another announcing "quelques dérangements." He CHAP. VI.] 167 THE ALGERIAN CABLE. remained till the end of October, but all his endeavours to make it right were in vain. • On the 11th November he wrote thus to Colonel Stewart: You will doubtless have heard that I have been unsuccessful with the Oran and Carthagena Cable. Upon the second attempt it was indeed quite successfully laid, and worked admirably for a few hours, when the cable broke, ten miles from Carthagena, upon the edge of a precipice which descends almost perpendicularly from comparatively shallow water to 2800 metres. I had given 25 per cent. slack in approaching the rising ground, which, according to the soundings (by the French Admiralty), rises gradually. The cable must have been for nearly a mile in tree suspension, and a fluctuation in the strength of the currents caused it to give way. The French Government admit that the soundings were to blame, and that a cable is not practicable in such a locality; they have therefore determined to go from Algeria to Sicily, Corsica, and on to Nice, and to charge me with the manufacture of the surplus length, making use of as much of the old cable as I shall succeed to take up. I took some up which had been laid in January last, and which was quite unaltered. It had been at 2400 metres depth. This alternative line was laid by the French Govern- ment in June, 1865, but no material portion of the old cable was recovered. The contract with the French government was of a complicated nature, and led to a law suit (which, however, was never decided, being stopped by the Franco-German war), but the great proportion of the expense fell on the Siemens firm. William felt the disaster very keenly, not only on account of the pecuniary loss, which would have gone far to swamp a less stable business; but from a natural feel- ing of disappointment at the failure of the first large • 168 [CHAP. VI. ACTIVE BUSINESS. telegraph operation he had taken on his own responsibility. He explained this to Werner, who, at the beginning of 1865 answered him, as usual, in encouraging language as follows: I hope you will begin the new year in good health and with fresh courage. May the end of it correspond to your hopes and expectations. You are right! the by-gone year has given you hard blows ;- but they were endurable, and what is most important I have been glad to infer from your letters that they have not weakened your courage or active power. If that is so, the material losses are of subordinate importance. Possibly fate may ordain that they may hereafter appear as gains ; the furnace and telegraph business still prosper, thanks to your indomitable activity and intelligent management. Misfortunes have at least the good feature that they warn us against presump- tion, and stimulate our prudence. The Indo-European Telegraph. Towards the end of this period, the two firms, Messrs. Siemens and Halske in Berlin, and Messrs. Siemens Brothers in London, executed jointly a work of great national importance and of high responsibility, namely the establishment of a line of land telegraphs forming a direct communication between England and India, and afterwards known by the name of the Indo-European Telegraph. The first telegraph communication from Europe to India was attempted to be made in 1860, by the laying of a submarine cable, under the auspices of the "Red Sea and India Telegraph Company," between Egypt and the West Coast of India. Egypt was already in telegraphic communication with Europe, and the new cable, which was 3500 statute miles long, was in six sections, passing from CHAP. VI.] THE INDO-EUROPEAN TELEGRAPH. 169 Suez by Kosseir, Suakim, Aden, Hallain, and Muscat, to Kurrachee, at the mouth of the River Indus, where it joined the Indian Government system. This cable was finished over its whole length in February, 1860, and was accepted by the company; but it soon failed, and in April 1861, four out of the six sections had ceased to work. There was naturally a great public outcry at this dis- appointment, and an attempt was made to meet the want by a combination of different routes, chiefly overland. The Indian Government proposed to lay a submarine cable from Kurrachee through the Persian Gulf. They consulted, through their agent, Colonel Stewart, R.E., Messrs. Siemens upon this project, and Werner and William Siemens sent in, in October, 1862, a joint report upon it. It was afterwards carried out. communicating, in the Persian Gulf, with Fao on the Turkish, and with Bushire on the Persian shore. From Fao the wire was continued by a Turkish land line to Constantinople, where it joined the general European system. An alternative line was also formed as follows:-the Indian Government continued the line by land from Bushire to Teheran; the Persian Government carried it to the Russian frontier at Djulfa, and the Russians then pro- longed it across the Circassian range into Southern Russia, where it also came upon the European system. Messrs. Siemens lent their aid in these works, supplying some of the materials for the land portions. The lines were opened in 1865, but from the very first they failed to satisfy the public demands. No dependence could be placed on the service; the charges were high; messages sometimes occupied weeks, and then came to hand unintelligible; the order of the messages was fre- quently inverted; and great confusion, uncertainty, and loss were occasioned. The untrustworthy character of the 170 [CHAP. VI ACTIVE BUSINESS. service at length became so burthensome that the Govern- ment was being continually importuned to move in the matter, and at length earnest efforts were made to bring about a better state of things. Messrs. Siemens were the most active agents in the change. In addition to their connexion with the existing lines they possessed large mineral holdings in the Caucasus, giving considerable traffic and requiring the permanent residence of their own agents in the country; and in this way they had acquired valuable knowledge as well as important influence in the locality. They had at an earlier period taken part in a scheme for establishing a company to construct and work an indepen- dent overland line from England to India, via Prussia, Russia, and Persia, and in 1865 negotiations were opened with the several governments, for obtaining the necessary concessions. These negotiations were chiefly carried on by the three brothers, Carl in Russia, Werner in Prussia, and William in England, in conjunction with General von Chauvin, the Director-General of Telegraphs for Prussia, General von Lüders, who filled the same post in Russia, and Colonel Bateman-Champain, who represented English and Indian interests in Persia. The following extracts from a letter from Werner to William, dated probably early in 1865 (the name of the month is lost), will give an idea what an important part the brothers played in this affair :— I have had a long conference with Chauvin, and as Lüders will be here in a few days, we must now take decisive steps in the matter of the Concession. By Chauvin's information the matter stands thus:- According to the Convention sent you, Russia and Prussia have agreed that they will establish the London-Teheran line, and Chauvin is commissioned to conclude the contracts, &c. Russia CHAP. VI.] THE INDO-EUROPEAN TELEGRAPH. 171 has already agreed to give a Concession for the construction through the whole of Russia, from the Prussian frontier. The material engagements on the other side consist first in the payment of five francs for a single through-message, and secondly in the laying of an additional wire for internal Russian correspondence, on payment to be agreed on. This wire will serve as a reserve for the Indian line. Russia and Prussia will also allow their other lines to be used for messages, if the line should be anywhere interrupted; this is very important. The five francs for Russia, and the two and a half francs for Prussia, are to be rateably reduced, if the states ever reduce their general tariff. Prussia will give the company a Concession for the construction of a line from England to the Prussian coasts, which the company can use at any time, if the agreement with the Electric Company should not be carried out, or extinguished, or if the present wires of the Electric Company should not suffice. Prussia will also undertake to place at the disposal of the company as good an amount of communication as they obtain elsewhere on the line. These fundamental conditions fully correspond with what we have desired ;-in regard to Russia they go indeed much further. As to the company to be formed, a convention must be con- cluded with Russia and with Prussia, which will regulate the whole matter. Chauvin is of opinion that England will also join, according to Major Champain's statements, so soon as the company is actually formed. He proposes with this object to visit England soon; and as he and Lüders will be in Paris next month, you will be able then to treat with both of them. This much is certain, that Prussia as well as Russia and England have the earnest desire, as well as the decided intention, to esta- blish the England-India line, and that they will make considerable sacrifices to carry out the matter. We must now take decided steps. We have really no ground for drawing back: the parties interested wait for our propositions, and will then treat with us. It would, perhaps, be best that you and Carl should come here while Lüders is here, and perhaps also Champain, to settle all with one blow. In any case I wait 172 [CHAP. VI. ACTIVE BUSINESS. for your contract-propositions as early as possible. as possible. In the form we must as far as possible give way, if we are to have the substance thoroughly favourable. The only difficulty relates to the telegraph officials in Russia. In Prussia good men will be chosen. As to finding the money, I believe we could do it here; but Chauvin, and Russia also, wish the introduction of English capital, and an English company. The question is now, Do you think that the capital, at least the greater part of it, can be found in England? And if so, can we retain the construction and mounting of the line securely in our own hands? If not, I will set about the preliminaries here. The most important thing, however, is to have an immediate sketch of the contracts with the governments. You have Carl's sketch of the Concession for Russia; and I hope to have your propositions as early as possible. From this time the negotiations were continually going on for three years, the Messrs. Siemens actively engaging in the necessary discussions. Sometimes William was sent for in great haste to Berlin, sometimes the brothers had to meet the representatives of the powers in Paris, and sometimes conferences took place in London. All this led to incessant correspondence, at first in negotiating the terms of the concessions; then in ar- ranging the route and the details of construction, and finally in discussing and settling the methods of carrying out the undertaking. In short, the burden of the whole matter, from its inception to the opening of the line, appears to have been borne on the Siemens's shoulders. At length they were prepared to act, and, armed with the necessary powers, they promoted the formation of ar English company to carry out, by private enterprise, what the States, with their inelastic arrangements, had failed to accomplish. This involved the erection of a new indepen- CHAP. VI.] THE INDO-EUROPEAN TELEGRAPH. 173 dent line of telegraph, about 2750 miles long, through Russian and Persian territory, from the Prussian frontier to Teheran, and so connecting the existing Prussian system (and through it the British Islands) with the lines of the Indian Government already described. The company was called "The Indo-European Telegraph Company," and it was formed in alliance with the Electric and International Telegraph Company. The prospectus was issued in April, 1868, and it was thus noticed in the City article of the Times of the 16th of that month:- A prospectus has been issued of the Indo-European Telegraph Company, with a capital of £450,000, to carry out the projected lines, for which concessions have been granted to Messrs. Siemens by the Prussian, Russian, and Persian governments. [Here follow descriptions of the undertaking, statements of the terms of charge, and so on.] The working is to be direct, and under English management throughout; the concessions are to be made over to the company by Messrs. Siemens, in consideration of their receiving one-fifth of the surplus profits over 12 per cent. ; and the same firm have tendered to complete the whole undertaking during the year 1869 for £400,000, and to maintain it for a further sum of £34,000 per annum. The entire scheme appears to have been honestly framed, and the board is composed of men of practical experience. In a commercial and political sense the importance of the work is unquestionable. One half the capital had been subscribed before the issuing of the prospectus, and the remainder was obtained immediately afterwards. Messrs. Siemens's tender for the construction of the line was sent in on the 27th of April, 1868; it was accepted early in June, and the lines were completed by the 10th of December, 1869. 174 [CHAP. VI. ACTIVE BUSINESS. The complete line from England to India, as worked by the company, passes from London to Lowestoft, thence by submarine cable to Norderney, then by Emden and Berlin to Thorn on the eastern frontier of Prussia, and thence by Messrs. Siemens's new line to Teheran, and so by the Indian Government lines to all parts of India. In order to give the company complete control over the communication, the Prussian Government agreed that there should be laid down, for their exclusive use, two additional wires, with separate posts, and under separate management, throughout their district, from Norderney to Thorn. By this arrangement, therefore, the whole communication from England to India is kept in British hands. The entire line is shown on the Map. We are only here concerned with that portion of it undertaken to be constructed by Messrs. Siemens. This, as already stated, was about 2750 miles long. Commencing on the eastern frontier of the Prussian dominion, it entered Poland, and passed eastwards through Alexandrovna, Warsaw, and Jitomir, to Odessa. From thence it was carried along the northern shore of the Black Sea and the Crimea, by Kertch and Poti, and through Circassia, to the Persian frontier at Djulfa, whence it pro- ceeded by Tiflis and Tabriz to its terminus at Teheran. In the course of the line were three submarine cables : one, about a mile and a half long, to cross the river Dnieper; a second, between II and 12 miles long, to cross the Straits of Kertch; and a third submerged in the Black Sea, east of the Crimea, between D'Juba and Scotcha. This latter part of the line required much careful considera- tion, and gave a great deal of anxiety. Werner, in one of his multitudinous and voluminous letters to William on the subject, 2nd Oct., 1867, gave a picturesque description of the state of the case. He said: 70 30 15 15 30 45 60 75 !

According to him it is possible to reach by land with mules as far as Anakspiga, about five miles northwards from Suchum Kalais, and as far as that he considers a land line practicable, but not a step further. From thenceforward mountains, thousands of feet high, go right to the sea, offering giddy perpendicular precipices, which probably descend equally deep under the sea surface, and offer no means of crossing them. If you desire to go from one valley to another, you have to travel a couple of days, climbing inland, and seeking a passage over the great Caucasian range. It is, however, projected to make a road over those heights, which perhaps may hereafter be useful to us. [The truth of this anticipation will be seen in the sequel.] In the meantime, it is certain that in the immediate neigh- bourhood of the coasts the sea has great depths. Near Poti, where the harbour works have caused the locality to be well examined, we have found three or four precipitous terraced descents, the first about 100 feet high, the latter much higher. The engineers who have sounded the Caspian Sea, have found two great hollows, one on the Caucasian, and another on the Persian coast, in the latter of which, at 6000 fathoms, no bottom is found! And it is the general opinion of the Russian geologists and engineers, that the Black Sea has similar formations, and that, especially on the shores of the Caucasus, very great depths exist. I regret to say that all this seems to me very probable. Sound- ing would be a long and very difficult work; we cannot measure the colossal Caucasian formations with the puny measuring rods we use ! This grave matter was subject to long discussions. The land line, owing partly to the physical mountain difficulties described, and partly to the fact of its passing through wild districts uninhabited by civilized people, had to be 176 [CHAP. VI. ACTIVE BUSINESS. abandoned; and for a long time Messrs. Siemens hesitated to take the responsibility of laying a submarine cable in such a sea. However, the latter alternative seemed the preferable one, and after more enquiry, William Siemens, who was never wanting in enterprise, resolved to undertake it, the operation of laying being performed under his own personal superintendence. The distance so to be traversed was 92 nautical miles; and the cable contained three separate conductors of the usual construction. The shore ends had a heavy sheathing of galvanized iron wires, covered externally with tarred jute, while the deep sea portion was armed by flexible copper sheathing, capable of resisting permanently both the attacks of the Teredo and corrosion by sea water. The cable being ready, Mr. Siemens left London, accom- panied as usual by his wife, on the 24th May, 1869. After a few pleasant days spent in Berlin, they went on by Vienna down the Danube to Pesth, thence to Rustchuk and Varna, and by steamer on the Black Sea to Constanti- nople. He wrote from there, dating the 17th June:- I expect the cable ship on Saturday, and to start on Monday next. We are highly pleased with Constantinople, which I learn is much improved in cleanliness; but we have moved to-day out to Therapia for freshness, and because we have found agreeable friends here. The Ambassador, Sir Henry Elliott, and lady are very kind, and much interested in the expedition. Yesterday Carl and I dined with Halel Pasha à la Turque, which was very amusing, and a most elaborate affair. My wife says she is very happy, and very well, in which I concur. They remained a fortnight in Constantinople, arranging business matters, and waiting for the arrival of the ship carrying the cable. On the 21st June they embarked on board this ship, named the Hull, and had a pleasant CHAP. VI.] 177 THE BLACK SEA CABLE. voyage for four days, when, within a short distance of their proposed landing-place, Poti, they were suddenly visited by one of the terrific Black Sea storms, and suffered many hours of tossing and suffering, after which they were enabled to land, crossing the dangerous bar in a steam tug. Lady Siemens's diary gives a graphic account of what she calls that "God-forgotten place," where, she says, "frogs of enor- mous size and mosquitos seem the principal inhabitants.” She was dangerously ill there, but was carefully and tenderly nursed by her husband. Being now arrived near to the site for the cable, the necessary preparations for submersion were made, the work was put in hand, and on the 14th July Mr. Siemens had the satisfaction of telegraphing to London the news of its successful accomplishment. This work being done, Mr. and Mrs. Siemens, accom- panied by Carl and his son, went from Kertch in their steamer to Yalta, where they landed and made an enjoy- able excursion, passing Livadia, Orianda, and Aloupka (the residence of Prince Woronzoff), and on through the valley of Baidar, by Inkermann and Balaclava, to Sebas- topol, which still lay all in ruins. From Sebastopol they sailed to Odessa, then went on to Galatz, and embarked there on a steamer bound for Vienna. On the 26th July they were in Berlin, and on the 9th August they arrived in London. The change and the pleasure of the journey had been beneficial to Mrs. Siemens, for, on her reaching home, her husband wrote- Anne is, I think, improved in health, but very thin, in conse- quence of the great heat, and the discomfort of Eastern travelling. The whole line of telegraph on land was laid with iron N 178 [CHAP. VI. ACTIVE BUSINESS. posts, special wire insulators, and every engineering and scientific improvement of the day, in order to facilitate its effective working. The construction of the line involved great difficulties, partly by physical obstacles, but chiefly by the fact of the line passing through an uncommercial and unsettled country, peopled in some parts by only semi-civilized races. In the first place, it was not an easy matter to get the necessary apparatus delivered upon the ground. The materials for the Persian portion of the line, consisting of 11,000 iron posts, 33,400 insulators, and 900 miles of wire of large section, were shipped to St. Petersburg, whence they were transported on the Neva and the Volga to Astrakhan, and again shipped across the Caspian for Len- koran, Astara, and Recht, the northern ports of Persia. At these ports it was found difficult to get beasts of burden to distribute the materials in the interior of the country within the prescribed time. Then when the materials were on the ground, their fixing met with new obstacles of a strange and unusual nature. The Circassians, who were often roaming about armed, and who had but little respect for law and order, used to find amusement in firing at the insulators, up- setting the posts, and damaging the wires;—and until they could be brought to good behaviour, the workmen and inspectors were obliged often to work and go about under a guard of Russian soldiers. Then some curious difficulties were found from the effects of great cold in winter, combined with some peculiar conditions of moisture in the air. Occasionally the wires would become surrounded with envelopes of frozen dew, increasing to some inches in diameter, which would weigh down the wires, or would break up into sepa- CHAP. VI.] THE INDO-EUROPEAN TELEGRAPH. 179 rate beads, hanging like huge necklaces between the poles. These conditions rendered necessary either extra strong wires, or short bearings, where they were found likely to occur. Then there were other evils. At some periods large numbers of the men were invalided by fever or other diseases; and one of the best German members of the staff died. There also occurred frequent quarrels with the natives, sometimes carried to bloodshed;-in one instance a good native servant was beheaded by swift native law, on a groundless charge of shooting a villager. But the good temper and spirit of the officers carried them through their difficulties, which indeed they often viewed on the amusing side. For example, one of the staff stationed in Persia, wrote to William in February, 1869, as follows:- The construction from Caswien forwards has given us much amusement, although sometimes we have been near sticking deep in the mire. We have had the opportunity of learning to ride, though not altogether to the advantage of our lower garments; for when I came here my inexpressibles were in three pieces! But we have come out safe and sound, and have laughed more than complained. Some days we stood with the labourers in the snow, waiting for material; the men shivered and grumbled; so we showed them how to make snow-balls, and then divided them into two parties, and got up a great battle. In the villages the people feigned a great respect for us, and brought us presents, which we had to pay for dearly. They would not work till we thrashed them, and they tried to cheat us in every way. With the Persians it is always 66 to-morrow ;" and to-morrow they have forgotten all they promised to-day. Yesterday H. and T., with some other Europeans, rode out to hunt hares, when H. fell into a hole thirty feet deep, and came out with a black eye. I should explain that the Persians make their water-conduits in a very peculiar way. They dig round holes in the ground two to four feet in diameter, and so deep, N 2 180 [CHAP. VI. ACTIVE BUSINESS. that water stands in them; they are laid out in a line, and then tunnels are driven in the earth from one hole to the other, and so the conduit is complete. It was into one of these holes that H. fell. However, on the whole, there is much to be learnt here, and I am very glad I came. At the end of October the line was so far advanced that attempts at speaking through to London were made, and by the end of 1869, as already stated, the contract, as regarded its essential work, was complete. General Telegraphic Work.-Mr. Siemens took out several patents during this decade, for improvements in the details of electric apparatus, many of which were applied and used in the operations of the firm. He also delivered two important lectures on Deep Sea Telegraphs at the Royal United Service Institution, one on the 23rd June, 1865, and the other on the 5th of March in the following year. In 1867 he laid before the British Association a description of a new form of Electrical Resistance Measurer-of remarkable practical utility for simplicity and cheapness of construction, ease of manipulation, portability, and for its being capable of employment with exactness by unskilled and inexperienced operators. Magneto-Electric Currents.-In 1867, the two brothers brought out a most important scientific invention in the domain of magnetic electricity, namely, the production of powerful currents without the aid of permanent magnetism. But as this invention, both in its nature and its results, is inseparably bound up with the Dynamo-Electric Machine, which only received its full development some years later, it will be convenient to postpone further notice of it till the next chapter. CHAP. VI.] 181 DOMESTIC LIFE. DOMESTIC LIFE. As stated in the last chapter, Mr. Siemens on his marriage went to reside at Twickenham. There he lived very happily for some years. He was always fond of the country, and he thoroughly enjoyed the pleasant freshness. and quiet of his country home. The couple were always ready to welcome their friends, but made no ostentatious display. Their principal pleasure was travelling. Indeed, for Mr. Siemens it was almost a necessity to have frequent change of scene. His business connexions and occupations re- quired him to be frequently away from home, and he generally contrived to combine his business journeys with those of recreation, feeling keenly the delight of getting away from the dark smoke of furnaces, and the busy hum of electrical manufactures, to scenes of beauty and interest. In August, 1860, he and his wife, accompanied by his wife's sister, went on a trip to Germany. On the 3rd of September, Werner and William attended a great meeting at Coburg, the object of which was to strive to promote German unity; they then joined the ladies at Kösen, greatly excited at the success of the gathering, and wearing the badge of the movement, Schwarz-roth-gold. On the 17th they went to Dresden to visit Hans Siemens, and to see his glass-works, in which the new regenerative gas furnace was about to make such important and successful changes. In August, 1862, he started with his wife for a long trip in Germany and Austria. Trêves was full of interest for him (having as yet never seen Roman antiquities in Italy). Vienna was also visited, and from thence a beautiful tour was made through Baden, over the wonderful Semmering Railway into Styria. Here he visited the great Steel Works of Meyer, and was naturally much interested in 182 [CHAP. VI. ACTIVE BUSINESS. the processes carried on there. They returned by Salz- burg and the Salzkammergut, Dresden and Berlin. Towards the middle of 1862 he found it necessary to remove his residence to London. His business was so extending that the loss of time in going backwards and forwards between his house and his office became a serious matter. Moreover, he was just contemplating the establishment of the large Electrical Factory near Woolwich, in a direction out of London diametrically opposite to that of his residence. And further, duties of different societies, scientific business, and social en- gagements, so increased on him that he found the distance from London hampered him in this particular also. He was indeed reluctant to give up the charm- ing locality of his Twickenham residence, which had hitherto been such a delight to him;-but the business considerations were imperative; and he hoped to com- pensate himself by more frequent pleasure-trips to a greater distance away. Accordingly he took a house called Aubrey Lodge, on Campden Hill, the highest point of Western London, and within a stone's-throw of Holland Park. This situation gave perhaps the maximum of fresh air and country appearance that could be obtained within a short drive of his office. Here he remained till 1870, and he soon found the advantage of the change of residence, not only in business facilities, but also in enabling him to increase his social enjoyments. Towards the end of this period, he indulged his hospit- able inclinations by giving occasional receptions, as large as his house would allow. These were full of life and interest: science, art, literature, and the reunion of different nation- alities always lent a brightness to them; and it need hardly CHAP. VI.] 183 DOMESTIC LIFE. be said that in all these entertainments and gatherings, his wife was his prominent coadjutor. The time saved from the daily railway journeys enabled him to extend the range of his studies and occupations. He now began to devote more attention to literary work. As early as 1851 he had attempted English composition, in the form of scientific and technical papers on subjects he was engaged in, and several successful efforts of this kind have been mentioned in former chapters. He increased the number of these, improving them in form and style, and offering them to circles of higher rank. During the decade included in this chapter we find that he wrote no less than twenty-two scientific memoirs, all which were favourably received, and willingly published by the bodies to whom they were presented. Many of them are noticed elsewhere. In some cases these were publicly read by the officers of the Societies; but he more usually read them him- self; for he was somewhat proud of the fuller knowledge he had acquired of the English language, and by no means hesitated to exhibit it when he had an opportunity. In addition to these papers he was also induced frequently to deliver lectures and addresses to smaller societies, schools, and other institutions; sometimes reading them, and at other times delivering them extempore. Many of these, though acceptable enough to their hearers, were not considered by Mr. Siemens important enough to pre- serve. For example, on the 15th of April, 1861, he gave a lecture in the City of London school, to gratify the wish of Dr. Mortimer, then Head Master. No description of this, or even mention of its subject, has been retained, but a memorandum made at the time records that the boys were delighted with the experiments made. 184 [CHAP. VI. ACTIVE BUSINESS. The expeditions to the Mediterranean in 1863 and 1864, ending so unfortunately, have been already noticed in their proper place. In the spring of 1866, he determined to indulge a desire he had long entertained, namely, to see Italy. He left with his wife in April; from Marseilles they drove along the Riviera, taking ten days to see it thoroughly; from Genoa they travelled to Pisa and Florence; and from thence to Padua, Ferrara and Venice: returning by Trieste, Vienna, Prague, Dresden, and Berlin. Here five of the brothers, Werner, William, Frederick, Carl and Walter, met together, and, as a listener remarked, the great aspirations manifested in their intercourse, were astonish- ing to hear! Later on in this year, however, he had occasion to take a holiday from a less pleasant motive. In the night of the 26th July, he was suddenly taken alarmingly ill; prompt remedies restored him in some measure; but he was at once sent away to Bonchurch in the Isle of Wight; a pretty cottage was taken for him for a month, during which time he was neither allowed to read nor write. often spoke of this enforced rest as a happy one; he said it was an easy life when he could get his wife to read and write for him, adding that sometimes he found he could trust her to do the thinking for him also. On 11th August, Werner wrote to him :— He Your communication about your illness has really frightened me. I hope rest and sea air will restore the old freshness; but you must for the future spare yourself more, and take care against too great exertion and excitement. About six years ago, when I was about your age, I found my upper storey beginning to trouble me ("aufzumucken wie der Berliner sagt "). Since that time I have been obliged to spare my head, and I feel nevertheless a consider- able diminution of my mental energy and power of working. We must draw in with advancing years! CHAP. VI.] 185 DOMESTIC LIFE. On his return home he stayed in London for a week or two, but he was advised to complete his cure by a trip to Scotland, and this so revived him that he returned full of ambitious new ideas and schemes. The Christmas holidays of 1866-7 he spent in Berlin, meeting there Mr. and Mrs. Carl Siemens, from St. Peters- burg, and Walter from the Caucasus. He then paid a visit to his married sister in Lübeck, taking pleasure in pointing out to his wife all the scenes of his youthful school days. In March 1867, Hans Siemens died, and William went immediately to Dresden, to be present at the funeral, and to advise with the family as to the carrying on of the large glass-works which had been under the care of the deceased. This resulted in the duty being taken by Frederick, in whose hands it has since remained. In the middle of the year he was frequently in Paris, on the occasion of the Great Exhibition. The 30th of June was the day of the "Grands Prix," presented by the Emperor, a fête that went off with all due éclat. In the middle of 1868, he had to mourn the untimely death of his brother Walter, German Consul at Tiflis, and agent in Persia for the Indo-European Telegraph. In the autumn, after attending the British Association, he deter- mined to take a good holiday in Switzerland. After visiting his wife's brother, then residing on the Lake of Geneva, he went to Chamouni, and ascended with two guides to the Grands Mulets, the half-way resting place in the ascent of Mont Blanc, his wife accom- panying him as far as the "pierre pointue." He made this ascent over the glaciers with his usual energy and determination; but unaccustomed as he was to this rough climbing, his exertion caused him fatigue and suffering for some time afterwards. The journey was 186 [CHAP. V ACTIVE BUSINESS. continued by carriage and mules over the Tête Noire to Martigny, and on to Leukerbad, crossing the Gemmi pass by the Kanderthal to Thun, Berne, and Paris, and reaching home on the 23rd September. The long expedition in 1869 to the Black Sea, to lay the Indo-European Cable, has already been described. CHAPTER VII. ACTIVE BUSINESS-continued. Age 47 to 56. 1870 to 1879.

TAKING a general view of Mr. Siemens's position at the beginning of this period, we find that the results of his ten years' practice since the time of his marriage and naturali- zation had been eminently favourable to him. The great heat invention, the Regenerative Gas Furnace, had been successful beyond his most sanguine hopes; it had not only acquired him great fame throughout the world, but had proved a fortune to him of itself. Then its latest outcome, the steel manufacture, was promising great things. The new processes, invented and elaborated by himself with his accustomed ingenuity and perseverance, 188 [CHAP. VII. ACTIVE BUSINESS. had been abundantly proved to be of the greatest value in the economy of British industry;-and the manufactory he had started for working the process offered at least fair prospects, though they were not afterwards realized. The electric business was also in a flourishing condition. A large factory had been successfully established, in which much profitable telegraphic work was being done; and which admitted of very large contracts being undertaken. Some of these were, by their nature, liable to much risk; the first submarine work had been unfortunate, and other worse disasters were in store ;-but the Indo-European line had shown the capability of the proprietors and managers for undertaking great works and for resolutely battling with the difficulties inherent in them, and there was no lack of confidence in entrusting important contracts into the hands of the firm. com- Moreover, the branch of engineering which this manu- facture represented was at this time of a peculiarly hopeful character. The industrial use of electricity was paratively a new thing, and was developing and increasing at a rapid pace. The feasibility of carrying on instan- taneous telegraphic communications across the widest oceans had just been thoroughly established; new inven- tions of importance were constantly arising, others of still greater magnitude were looming in the distance, and no one with any scientific knowledge, or with any commercial foresight, could doubt that a great future was opening for the application of this source of mechanical energy. And if such a future did come, it was pretty clear that the brothers Siemens-men not only thoroughly versed in the science of electricity, but who had probably done more in its practical use than any other individuals—must come in for their full share of the benefit its application would realize. CHAP. VII.] POSITION AND PROSPECTS. 189 Then Mr. Siemens had by this time a high personal reputation. He had, years before, been admitted to the ordinary technical grades certifying to his scientific and professional qualifications ;-but he had now advanced beyond this to a standing implying special distinction. He had shown, by practical proofs, his complete mastery over the sciences with which he had to do,—and his views and opinions commanded respect and deference. He counted the most eminent men of science among his intimate friends, and in his own professional circle he received every mark of admiration and esteem. Mr. Siemens, therefore, had every reason to be well satisfied with his position;-and as, in the year 1860, he had taken a new departure by increased activity in his most promising occupations, so now in the year 1870, having achieved a reputation and a competence, he de- termined to take advantage of both. And this he did in two ways. In the first place he resolved to increase his social and personal enjoyments, partly by mixing more freely in society;-partly by enter- taining his friends and acquaintances in larger numbers and in better style; and partly by stealing away more time than he formerly could for his greatest delights, a country life or foreign travel. Then, secondly, he determined to take advantage of his better position by devoting more time and attention to matters which, though less profitable, were of a higher mental order. He wished to cultivate more freely the scientific views of his occupations;—to study scientific processes, or to propose scientific inventions. And in connexion with this he went more than formerly into literary work: writing papers; giving lectures; attending and taking part in scientific societies; and so on. These 190 [CHAP. VII. ACTIVE BUSINESS. were occupations that he had always liked, but in which the inexorable demands of business had heretofore for- bidden him to indulge so freely as he desired. It must not, however, be inferred from this that he was ever led to neglect his business or his practical work; or to underrate the value of his own personal part in it. In fact he had still plenty to do, and he did it conscientiously; but having now thoroughly good and trustworthy coadjutors and assistants, the strain of his personal attention became less onerous than formerly. He was still not freed from the uncertainties of com- mercial business, and he was doomed to suffer some terrible trials. But his old patience and endurance did not forsake him, and he bore them nobly. The subjects desirable to chronicle here, as engaging Mr. Siemens's attention during these ten years, are, the prosecution of the steel manufacture and other metal- lurgical applications of the Regenerative Gas Furnace ;— electric telegraphs, including submarine lines of great magnitude;—and the application of powerful electric currents to lighting and other uses. To these we must add now, a special head for miscellaneous inventions of a scientific nature; and another for his relations with scientific societies, for lectures, addresses, and literary work of various kinds. This decade formed the most active period of his life, it included the greatest amount and variety of important work, it was fraught with the most stirring incidents, and its record must necessarily occupy a considerable space in his biography. CHAP. VII.] THE STEEL MANUFACTURE. 191 HEAT AND METALLURGY. The Steel Manufacture. In the last chapter we had to chronicle the origin and progress of Mr. Siemens's inventions for the production of steel, culminating in the establishment of the works of the "Siemens Steel Company," at Landore, for carrying on its manufacture. At the commencement of the present period these works had just come into operation, and Mr. Siemens was much occupied in regard to them. The quality of the steel made there was good, and the demand for it was increasing. In July, 1870, more than 100 tons of steel rails per week were sent out, besides cast- ings and forge steel; and in August, 1871, the works were fully occupied, and had orders for some time in advance. There was, therefore, every encouragement to enlarge the establishment; an additional plot of land was taken, very favourably situated, and new works of a more extended character were laid out upon it, including not only the steel-making plant, but blast furnaces to smelt the iron; and the company also took collieries, to provide themselves with coal. It need hardly be said that Dr. Siemens used every endeavour to make the works as perfect as possible, and to introduce therein not only the best results of his past experience, but every new improvement that his ingenuity could devise. Money was not spared for buildings and plant; and by the year 1873 the Landore Works were making some 1000 tons of steel weekly, and had the character of being the largest steel-making works in exist- ence after those of Krupp, the Barrow Company, and one great Sheffield firm. Dr. Siemens was not, however, satisfied with turning out 192 [CHAP. VII. ACTIVE BUSINESS. a large quantity of steel; he wished to gain a special repu- tation for excellence in quality. It had been a reproach to some of the other new steel-making processes that, though they could make steel in large quantities at a moderate price, and though occasional samples might be very good, yet the general quality could not be depended on, to such an extent as to justify the use of the material in cases where good and trustworthy properties were absolutely necessary. One of these cases was the use of steel for ship-building. Naval architects had seen for some years the new metal supplanting iron for rails, for machinery, and for many other important purposes. It had been, moreover, clearly proved that good steel was much stronger than iron of equal size, and the opportunity of saving weight by its use was very attractive. For this reason attempts had been made to introduce steel for the construction of vessels; but they were met by the difficulties as to trustworthiness in quality, and the imperative demands of safety interfered with the practice. The merchant service, who were bound by Lloyd's Rules, succeeded in getting some concessions in dimensions by the use of steel under certain stringent conditions; but the Government, more cautious on account of the increased perils of war-ships, could not see their way clearly to a similar policy. In 1864 the Admiralty instituted an elabo- rate series of experiments on steel at Chatham Dockyard; and the results were very remarkable. The material was proved to be one-third stronger than iron when it fractured fairly; but it had an erratic mode of breaking, which showed the danger and uncertainty to which ships would be exposed if constructed of this metal. Years passed, and still the uncertainty remained. The French, bolder than our builders, had adopted Bessemer CHAP. VII.] THE STEEL MANUFACTURE. 193 steel in their ships of war; but their use of it was bound up with such excessive precautionary measures, that our Admiralty declined to be hampered by imitating them. Such was the state of the question when, in the year 1875, Mr. (now Sir) Nathaniel Barnaby, C.B., Director of. Naval Construction of the Royal Navy, read before the Institution of Naval Architects a Paper on Iron and Steel for Ship-building, at the close of which he said :- The uncertainties and treacheries of Bessemer steel, in the form of ship and boiler plates, are such that it requires all the care which it has bestowed upon it at L'Orient to avoid failure. The question we have to put to the steel makers is, What are our prospects of obtaining a material which we can use without such delicate manipulation, and so much fear and trembling? We have gone on for years using iron plates which are a compound of impure irons, of different and unknown qualities, welded together imperfectly in the rolls. We want a perfectly coherent and definitely carbonized bloom, or ingot, of which the rolls have only to alter the form in order to make plates with qualities as regular and precise as those of copper and gun metal, and we look to the manufacturer for it. I am ready, for my part, to go further than the French architects have gone, and build the entire vessel, bottom plates and all, of steel; but I know that at present the undertaking will involve an immense amount of anxiety and care. We ought not to be behind any other country in this matter, and it shall not be my fault if we are. This challenge could not fail to attract Dr. Siemens's attention. He had already, as has been stated above, long been aiming at excellence in quality, and he had had, no doubt, shipbuilding purposes prominently in view. What was wanted for this purpose, in plates or bars, was a soft material, only slightly carburetted, or as it was termed, “mild," in chemical composition; combining O 194 [CHAP. VII. ACTIVE BUSINESS. the mechanical qualities of good tensile strength with high ductility; and above all, which would be thoroughly uniform and trustworthy. He now took up the subject with increased energy and determination; he conducted a series of experiments lasting over some months, specially directed to the manu- facture of plates and other forms needed in shipbuilding ; and he succeeded in producing them in the quality he desired. This being done, the representatives of the Landore Works obtained an interview with Mr. Barnaby, and explained to him that they were disposed to accept his challenge. The Admiralty considered their propositions, and after the lapse of some months, devoted to the testing of speci- mens of steel supplied by the most eminent firms in the country, a contract was entered into between the Admiralty and the Landore Company for the supply, by the latter, of the plates, angles, and beams, to be used in the construction. of two armed despatch vessels, the Iris and the Mercury, to be built at Pembroke Dockyard. These vessels differed in important particulars from the ordinary heavily iron-plated ships, being designed with the special object of securing lightness and speed. To attain this end attention was naturally turned towards the use of steel, and Mr. Barnaby was glad to accept Dr. Siemens's offer. Each of the vessels was 300 feet long, 46 feet broad, and with a displacement of 3735 tons. The steel was supplied, and was subjected to the most stringent tests, fulfilling satisfactorily the required con- ditions. A full account of these tests was given by Mr. Riley, the manager of the Landore Works, in a paper "On Steel for Shipbuilding as supplied to the Royal Navy," read at the Institution of Naval Architects on the 7th of April, 1876. CHAP. VII.] THE STEEL MANUFACTURE. 195 In speaking of this transaction at a subsequent time (Report of 15 June, 1882), Mr. Barnaby said :- The difficulties arising from defects, the anxiety, the labour attending the investigation of the Inspectors' Reports, and the great cost, induced us to recommend their lordships to authorize the building of the Iris and Mercury of steel, of a quality not known in the English market, but offered by Dr. Siemens in conformity with our Specifications. The Landore Works acquired great fame, and were often visited by persons interested, such as the members of the Scientific and Engineering Institutions, who sometimes came in numerous parties. Dr. Siemens always received such visitors in the most friendly way, and showed them everything that was to be seen. In 1876, while the orders for the Admiralty ships were in hand, the representative of the Engineer journal visited the works, and descriptions of them were published in that periodical of June 23rd and 30th, and July 7th. These may be referred to for a general idea of the magnitude of the concern. It is sad, now, to be obliged to speak of a reverse side to the picture; but it must be said that notwith- standing the fame of the Landore Company, and the abundance of their orders, they had for some time, been in anything but a prosperous condition, in a commercial point of view. The enlargement and extension of the works had been encouraged by the acknowledged excellence of the manufacture, and the flourishing state of the iron market in the early days of the concern. But in after years, owing to the ruinous fall in prices, to diffi- culties in the management, and to other causes, the pro- perty became largely deteriorated in value, and the share- holders had to submit to great losses, Dr. Siemens himself (who made every self-sacrifice to carry on the works), being the principal sufferer. 0 2 196 [CHAP. VII. ACTIVE BUSINESS. It is right, however, to add that this result was not in the least respect due to any failure in the processes of manufacture. The produce of the works was always kept up of unexceptionable quality, the steel made there bearing always a high character. It was supplied to some of the best firms, and was used for the most important purposes. Through all the financial troubles of the Landore Company the production of high class steel from their works never stopped, and it is carried on to the present day. The use of the Siemens and Siemens-Martin processes has now largely extended, and the metal produced by them has proved of excellent quality. Sir William Siemens estimated that the quantity of steel which had been made by his processes to the end of 1882, amounted to about 4,000,000 tons. The production now, in Great Britain alone, is nearly 1,000,000 tons per annum. Production of Iron and Steel direct from the Ores. When Mr. Siemens was first designing his steel-making processes, he had conceived the possibility of carrying his improvements further. In his own method the produce of the blast-furnace formed the principal basis, being used either as pig metal, or as puddled iron, or both. But he expressed his belief that the direct conversion of ores into iron and steel would ultimately be accomplished, and he directed much attention to this object, which indeed formed one of the chief subjects of experiment at the Birmingham Sample Steel Works mentioned in the last chapter. In 1866, he was in treaty with a Mr. Henderson of Glasgow, for trying experiments on the reduction of certain ores; he took out a patent in September of that year, and CHAP. VII.] THE DIRECT STEEL PROCESS. 197 designed a furnace for Mr. Henderson according to his plans. In the steel-making patent of August, 1867, further reference was made to this subject, and at the beginning of 1868 he had erected a new furnace for the purpose at Birmingham. In his lecture to the Chemical Society in 1868, he gave some more detailed indication of his views. After de- scribing the pig-iron process, he said :— It would be unreasonable to expect steel of really high quality in using those materials which are already contaminated in the blast-furnace, and I am sanguine in the expectation of producing cast-steel superior in quality and at a low cost directly from the better description of ores. My experiments in this direction extend over several years, and last year I sent to the French Exhibition a few bars of steel produced from hæmatite ore which had stood a high test in Kirkaldy's machine. He then described, with some elaboration, the furnace which he had contrived. But he afterwards found the results unsatisfactory, and he accordingly changed his plans. He took out further patents in 1868 and 1869 for various modes of accomplish- ing the object, particularly one in which a rotatory cylinder was introduced, in conjunction, of course, with the Siemens furnace, which played a prominent part in all these metal- lurgical operations. He hoped to do great things with this process at the Landore Works, for, writing in September, 1868, he said :— Whatever happens, the ore arrangement must not be postponed, because steel from the ore must be the Cheval de Bataille of the new Company. With this view, experiments were instituted at the Landore Works, where a rotatory furnace was erected; but as he 198 [CHAP. VII ACTIVE BUSINESS. found that such experiments could not be satisfactorily carried on without interfering with the business arrange- ments there, he determined to resume them at the old Sample Works at Birmingham. These experiments were at once put in hand, under the charge of a relation, Mr. Alexander Siemens (subsequently appointed one of his executors), who had come to Dr. Siemens as a pupil some years before. In March the process was in good trim, and many visitors from Landore and other places called to see its working. In April, some of the results were sent for exhibition in London, together with a model of the new furnace; and samples of the products were also sent to Vienna. The experiments were carried on at Birmingham more or less till the spring of 1874. Meantime, in 1873, he had brought the subject forward again prominently before two eminent bodies, viz., in another lecture before the Chemical Society, the 20th March, and in a paper given to the Iron and Steel Institute on the 20th April. He described two modes of effecting his purpose, one by means of a stationary and the other by means of a rotative furnace chamber, the former being applicable chiefly where comparatively rich ores were available, and the latter for poorer ores. The paper at the Iron and Steel Institute excited much attention, and the subject was discussed at considerable length by many of the best authorities in the iron trade, who all admitted the great importance of the subject, and expressed high appreciation of Mr. Siemens's labours. Samples were exhibited of steel produced by the process, of very high quality. Encouraged by this success on a small scale, he ventured upon some larger applications, the principal one of which was made at Towcester, in the iron producing districts of Northamptonshire. Three rotative furnaces were put up • CHAP. VII.] THE DIRECT STEEL PROCESS. 199 there, and the results were given at considerable length by Dr. Siemens in another paper read before the Iron and Steel Institute at Newcastle-on-Tyne the 17th of September, 1877. These results showed that iron and steel of very high quality could be produced by the direct process from the ores then available, but the question still remained, at what cost could this conversion be effected? and Dr. Siemens was of opinion that the experimental works at Towcester were not sufficiently complete to determine this question. A long discussion followed Dr. Siemens's paper, in which many eminent metallurgists and practical iron makers took part. Mr. Bell, M.P., F.R.S. (now Sir Isaac Lowthian Bell, Bart.) said :— With regard to Dr. Siemens's paper, whatever might be its com- mercial results, it was impossible to over-estimate the value of such researches as those in which he had in recent times distinguished himself; because whether they led to commercial success or not, much was learnt in their prosecution, and thanks to his candour the Institute might always count upon having laid before them, so far as he was able to give it to them, a true exposition of the circumstances attending those researches. Mr. Bell afterwards said in a letter to Dr. Siemens, 12 November, 1878- I am engaged on an examination into the various processes of making iron, and among others that known as the "Direct." I have been reading over again your two papers on your own work in this direction, and have compared what you did with what I have seen of Clay's, of Chenot's, and of Blair's. I must admit, on closely-argued grounds, there are things which require careful study to disprove, although, as you know, I have a kind of instinctive opinion that the Blast Furnace will be difficult to exterminate. Dr. Siemens persevered for many years in his object, and designed many inventions to promote it. Indeed, the metallurgy of steel and iron was perhaps the most fruitful 200 [CHAP. VII. ACTIVE BUSINESS. subject of his inventions, for between 1863 and 1881 there appear no less than twenty-seven patents which have this object directly contained in their title, as well as many others for furnaces and heating arrangements. But Mr. Bell's instinct was right, for notwithstanding all these inventions, it must, we fear, be admitted that the direct iron and steel making processes never fairly passed beyond their experimental stage; and what would have been their future had their originator lived to carry on his researches can now only be matter of speculation. ELECTRIC TELEGRAPHS. During the ten years comprised in this chapter, the factory at Charlton was particularly active. In 1869 it had been decided that Mr. Carl Siemens, after the death of his wife, should come to London and take personal part in directing the concerns of the firm, in which he had a large monetary stake. The contracts increased considerably both in number and in magnitude, and at Carl's urgent instance the works were considerably enlarged from time to time. The firm executed much ordinary telegraph work, which it is unnecessary here to specify, but some of their larger contracts have to be mentioned on account of William's connexion with them. Indo-European Telegraph. In the last chapter it was stated that this line of tele- graph was essentially completed, according to the contract, by the end of 1869. But some further arrangements had to be made before the public could be allowed to use it, and in the meanwhile some disasters occurred which further retarded the formal opening. The circumstances CHAP. VII. THE INDO-EUROPEAN TELEGRAPH. 201 that caused the delay are worthy of description, as they may give an idea of the difficulties that had to be con- tended with. We give them from the inspectors' reports made at the time. The maintenance of a considerable line of telegraphic communication during the first twelve months of its existence is always a task of some difficulty and disap- pointment. The wires composing the lines, however care- fully prepared, will betray hidden defects; the posts will yield where the ground is treacherous; and the insulators are liable to be wantonly destroyed by the mischievous persons of any community where the telegraph is a novelty. These difficulties had particularly to be ex- pected in this case, and were guarded against by the appointment of a considerable working staff of guards and superintendents of the line. There were other troubles of a different character, and more difficult to be dealt with. At the beginning of the year 1870, immediately after the completion of the works, weather of extraordinary severity set in in Persia and the South of Russia, beginning with sleet and heavy falls of snow, and followed by intense cold, the thermometer falling sometimes to 70° Fahr. below freezing point. The wires, being weighted by a thick coating of sleet, were drawn tight by the cold and broke in hard places, or at defective joints. These fractures, however, would not have been very material but for other evils. In Eastern Russia, where the stoppage occurred, the contractors had been required to use a peculiar kind of insulator, which, though good enough on European lines generally, did not suit very rough climates and uncivilized inhabitants: they collected the snow, which spoiled the insulation; and moreover they were easily broken by stones mischievously thrown 202 [CHAP. VII. ACTIVE BUSINESS. at them by the natives. These had to be taken down and changed for a more suitable pattern. In the spring, when the weather became milder, the line was got into order: after some preliminary trials, at the beginning of April the direct communication between London and Teheran, a distance of 3700 miles, was declared open, and on the 12th of that month a party of gentlemen interested in the undertaking met Mr. Siemens at the London office in Telegraph Street, to test the speed and efficiency of the service. In this line use had been made of the Siemens system of Relays, by means of five of which, messages could be sent direct throughout this great distance (about one seventh of the circumference of the globe) without re- transmission by hand at any intermediate station. Major Smith, of the Indian Government telegraphs at Teheran, telegraphed: "What is your time?" He was answered from London: "Eleven fifty. What is yours?" The answer came: "Three twenty-seven P.M., as near as we can say." General Sir W. Baker, K.C.B., Member of the Council of India, who was present, with the object of testing the through communication with India, then sent at 12.45 P.M. the following message: "Sir William Baker to Colonel Robinson, Calcutta ; am delighted with working of Indo- European line through to India." The answer from Calcutta arrived at 1.50: "Calcutta, 7.7 P.M. Director of Traffic to Sir William Baker, London. Thanks for your message received in 28 minutes. Will send on to Colonel Robinson." Other messages were sent with equal success. This trial being so satisfactory, preparations were made for opening the line to public traffic. It was, CHAP. VII.] THE INDO-EUROPEAN TELEGRAPH. 203 however, necessary to devote a month or two to the improvement and regulation of the details, and all was nearly ready when, on the 7th July, a most unexpected calamity occurred, namely, the destruction of the land lines in Georgia, and of the cable lines in the Black Sea, by an earthquake. The land lines were thrown down, and the wires torn asunder in many places; but this was the least portion of the mischief, and could soon have been remedied. The worst evil was the damage to the submarine cable east of the Crimea. This had remained in excellent working condition till the earthquake, which tore it asunder in two places. A steamer, furnished with all necessary appliances, was immediately despatched from Kertch; but in endeavouring to raise the cable it was found in one place to be covered with earth, which could only be accounted for by a sub- marine landslip having taken place. It was evident that, to repair the line, more spare cable would be required than was on board, and it was not possible to obtain a fresh supply from England without causing great delay. In the meantime, the objection to the land line had been removed by the construction of a coast road under Russian authority, which made the country around much more secure. After carefully weighing all the circumstances, it was decided to abandon the cable, and to substitute a land line along the coast, which, by the friendly concurrence of the Russian Government, was completed by the end of the year. Messages passed again through the entire line on the 1st January, 1871, and the public traffic commenced upon it on the 31st of that month. It need hardly be said that the occurrence of these mis- fortunes, which not only brought disappointment and delay, but threatened great pecuniary loss, caused Mr. Siemens great anxiety during the whole of the year 1870. But in 204 [CHAP. VII ACTIVE BUSINESS. this case, as in the many troubles which had before befallen him, he went steadily on working, hoping, and relying on his own perseverance, and on the energy of his excellent and loyal coadjutors in each country through which the lines passed. Since the opening the line has been regularly and suc- cessfully worked, and although temporary interruptions are unavoidable, especially in Southern Russia, where the line is exposed to heavy storms, and to the accumulation in winter of masses of ice on the wires, they have generally been of short duration. It may also be added that, in a commercial point of view, the Indo-European Company has been one of the most flourishing of all the telegraph undertakings. The proprietors of the line have always held in high esteem the services in regard to it rendered by Messrs. Siemens. Independently of their successful construction of such a long length of line in the face of such remarkable difficulties, it was felt that the original conception of the idea, and its carrying out into a practical shape, was in a great measure due to them. They were undoubtedly the chief agents in carrying through the agreements with the various governments and other parties who had to be propitiated or negotiated with. The elaboration of these agreements, so as to satisfy all parties, and to obtain a reasonable commercial result for the company, was from first to last left with them. All this required diplomatic work of no mean order; and one of the principal directors of the company has said to the author of this biography, "I have always regarded this line of telegraph as a most remarkable achievement, and I much question whether it could have been carried through so successfully by any other parties than Messrs. Siemens." CHAP. VII.] THE INDO-EUROPEAN TELEGRAPH. 205 In 1873, on the occasion of the visit of the Shah of Persia to England, the apartments occupied by him were placed in direct communication, through the Indo- European telegraph, with his own residence. On the night of his arrival, his first act was to pay a visit to the room where the apparatus was placed, and in consul- tation with his Grand Vizier, to communicate at once with Teheran. Dr. Siemens was present, and had the honour of an introduction to the Shah, who conversed for a long time with him, and sat by the instrument;—deeply in- terested, as sentence after sentence, flashed direct from his capital, was received before his eyes, and transcribed by the Grand Vizier for his perusal. Dr. Siemens was highly complimented by the Shah on the great achievements of his company, and the telegraph was used amply during his stay. Long despatches passed daily in cipher on affairs of state, and in addition to these a vast number of messages were transmitted in French, on domestic matters; their nature indicating that family feeling was as warm amongst the Persians as amongst other people, and affording another proof, if any were needed, that human nature is very much the same all the world over. The Shah did not forget the trouble that Dr. Siemens had taken to serve him, nor were his compliments mere form, for after his return to Persia Dr. Siemens received the following letter, which may form an appropriate conclusion to our history of the Indo-European Tele- graph:- MONSIEUR,- LEGATION DE S. M. I. LE SCHAH DE PERSE, À LONDRES, le 15 Octobre, 1875.

En vous communiquant cet avis officiel, je suis heureux de pouvoir vous exprimer mes félicitations sincères ainsi que mes sentiments très distingués. À Monsieur le Dr. C. W. SIEMENS. MALCOLM. Direct Atlantic Cable. At the beginning of 1873 the firm undertook their first great submarine work, namely, the construction and laying of a cable across the Atlantic. This was for the "Direct United States Telegraph Company." The prospectus was issued in March, 1873. The capital was to be £1,300,000. The object was stated to be "the establishment of direct and independent tele- graphic communication between the United Kingdom of Great Britain and Ireland and the United States of America." Dr. C. W. Siemens was named as the "Con- sulting Director," and the Manager and Electrician was Mr. G. Von Chauvin. The line was to be 3060 nautical miles in length, to extend from Ballinskellig Bay in Ireland, to Torbay in Nova Scotia, from whence it was continued, also by sub- marine cable, to Rye Beach in New Hampshire, there join- ing the American land lines. The term "Direct" was used because this line was the first which, starting from the United Kingdom, gave direct communication by submarine cable with the United States; all the former cables ended on Canadian territory, and reached the United States by land. It had to be of greater length, and greater conducting power, than any one previously laid. The cable consisted, for the deep-sea portion, of copper conductors, gutta-percha insulators, and a sheathing of CHAP. VII.] 207 THE "FARADAY." steel wires covered with hemp; the shallow-water part consisted of similar conductors and insulators sheathed with hemp, which in turn was covered with iron wire. This work is noted as having given rise to the construc- tion of a special steam vessel for laying the cable. For the first Atlantic Cable the Great Eastern steam- ship had been used, and others more or less suitable had been employed for submarine work ;—it was not till 1872 that any vessel was specially built for the purpose, when Hooper's Telegraph Company had their cable steamship, the Hooper, constructed at Newcastle-on-Tyne. This vessel had done good work; but Dr. Siemens, bringing to bear on the subject the knowledge and experience he had already gained, as well as the study he had made of the Atlantic question some years before, conceived that the requirements of the laying operation could not be efficiently met by any existing type of vessel, and he resolved to design one specially for the purpose. The result was the production of a fine new steamship, which, in compliment to the great electrical philosopher, was named the Faraday. She was built by the firm of Mitchell & Co., of Walker, Newcastle-on-Tyne. She was commenced about the middle of 1873, and was launched on the 17th of February, 1874, in the presence of a large party, Mrs. Siemens performing the "christening" ceremony. Dr. Siemens described the vessel in a lecture to the Royal Institution on the 15th May, 1874; which is pub- lished in their proceedings. The steamer is about 5000 tons register, 360 feet long, 52 feet beam, and 36 feet deep. In her interior are three enormous tanks, capable of stowing, under water, 1700 miles of cable. She is propelled by twin-screws so arranged as to give great facility in manœuvring. She 208 [CHAP. VII. ACTIVE BUSINESS. is fitted with all proper machinery for laying and picking up the cables; and for performing all other necessary operations in regard to the work. A view of the ship is given in the accompanying Plate. The success of this ship, for the delicate and difficult purposes she was intended to serve, was perfect, for she proved herself capable of laying and lifting cables at all depths, in all seasons, and in almost all weathers;-and it has been well remarked that the design of such a vessel, capable of doing what no other vessel afloat could do, by a landsman, born in the interior of Europe, whose education and pursuits had little or no connexion with nautical affairs, was a striking example of practical genius of the highest character. In April the Faraday steamed from Newcastle to London, Dr. Siemens being on board. She sailed, to commence the laying of the Direct Atlantic Cable, on the 16th May, 1874. The expedition was in charge of Mr. Carl Siemens, and the manager of the firm, Mr. Loeffler, was also on board. She carried on this occasion the cable for the American sections and shore ends. She arrived off the American coast early in June, and was there joined by the Ambassador, a ship also sent out by Messrs. Siemens to assist in the laying. The work was much delayed by foggy weather; and on the 2nd July there appeared in the Times the following startling announcement, communicated by Reuter's tele- grams:- The steamer Faraday has struck on an iceberg off Halifax, and is a total wreck. The consternation caused by such an announcement may well be imagined, but not a moment was lost; [Page 208. FARADAY THE TELEGRAPH CABLE STEAMSHIP "FARADAY." CHAP. VII.] THE DIRECT ATLANTIC CABLE. 209 Siemens sent telegraph Messrs. telegraph messages in all directions to gather information. After some hours of suspense impossible to describe, everything pointed to the explanation that the rumour was the rumour was a mere Stock Exchange panic. Messrs. Siemens obtained the assur- ance that the report was without foundation, and they authoritatively announced this in the Times of the next day. But not till news came, as it did soon afterwards, from Carl Siemens, did the family feel relieved of the load of anxiety. The Faraday arrived safely at Woolwich on the 6th of August, having completed all the work she had then to do. On the 26th of August, 1874, she again left Charlton, with the main cable on board, to be laid under the super- intendence of Mr. Carl Siemens. She arrived at Ballin- skellig Bay on 1st September, and having attached the cable to the shore end, she commenced paying out on the 6th September, accompanied by two tenders, the Ambassador and the Dacia. She had laid about 500 or 600 miles when Dr. Werner Siemens, who was testing the cable from the shore at Ballinskellig Bay, found that a very slight fault had passed overboard. Hitherto it had not been customary to stop operations for faults of so trifling a character, as being too unimportant to interfere with the proper working of cables. But the brothers were determined that this cable should be as perfect as human skill could make it, and they therefore agreed to haul back and cut out the fault. In doing this the cable broke, but it was picked up again within 48 hours in 2680 fathoms of water, successfully spliced, and the lay- ing proceeded with. This picking up of the cable out of a depth of nearly 3 miles is noteworthy, as being the first time that such a feat was successfully accomplished. Owing to severe weather, to the loss of grapnels which P 210 [CHAP. VII. ACTIVE BUSINESS. had been broken in consequence of the rocky bottom upon which operations were being carried on, and to the supply of coal running short, the Faraday and her two tenders were eventually obliged to put into Queenstown to effect some repairs, and to obtain coals and supplies. William Siemens visited them there on the 10th October, and the Faraday left again on the 23rd. The principle of eliminating even the smallest faults was rigidly adhered to, although the completion of the cable was much delayed thereby; but since it has been handed over to the proprietors, it has proved to be one of the most satisfactory cables ever laid, and its rate of transmission is far superior to that of cables in which minute faults have been allowed to remain. The Brazilian Cable. In 1874 the firm engaged in another large submarine cable undertaking, which, though ultimately successful, was attended in its progress by sad disasters. It was a contract with the Brazil and River Plate Tele- graph Company, for manufacturing and laying a telegraph between Rio de Janeiro and the Coast of Uruguay, near the Brazilian frontier, in all 1130 nautical miles of sea cable, and 50 statute miles of land line. The cable was to be laid between various points of the coast near Rio de Janeiro, Santos, Santa Caterina, Rio Grande do Sul, and the River Chuy on the coast of Uruguay, near the Brazilian frontier. It consisted of seven copper wires insulated with gutta percha, covered with jute yarn, and sheathed with galvanized iron wire. The steam-ship Gomos was sent out with a portion of the cable and with stores and materials, to the Brazilian CHAP. VII.] 211 THE BRAZILIAN CABLE. coast. She laid successfully one of the sections of the cable; but on the night of the 25th of May, 1874, she struck on a sand-bar at Rio Grande do Sul, and became a total wreck, losing about 204 nautical miles of cable, which were still on board intended for another section. In November, 1874, another steamer, the La Plata, was sent out with 184 nautical miles of cable, and materials, to replace those lost in the Gomos; but three days after her departure, on entering the Bay of Biscay, she foundered in a violent gale, with the loss of fifty-eight lives. The story is a very painful one, but on account of its great personal interest to William Siemens, it is necessary to tell it some- what fully. The La Plata was a fine iron screw steamer of 968 tons register, belonging to Mr. W. T. Henley, of London, and she was chartered by Messrs. Siemens for this work. She was "well found," as the term is, in every respect, and, indeed, Messrs. Siemens (as will be mentioned hereafter) added more to her provisions for safety than they were bound to do. She was commanded by Captain J. H. Dudden, an experienced seaman, in whom every confidence was placed, and the cable was put on board and the ship prepared for the voyage, under the direction and to the satisfaction of the captain and his officers. She left Gravesend on Thursday the 26th of November, having seventy-five persons on board, including Mr. F. H. Ricketts, who had charge of the expedition on behalf of Messrs. Siemens. The weather was fair for the commence- ment of the voyage, and she was off the Isle of Wight on Friday morning, when the pilot left. She then steered for Ushant, and towards Friday evening the wind began to freshen; it kept increasing that night and all the next day, P 2 212 [CHAP. VII. ACTIVE BUSINESS. until on Saturday night it was blowing a heavy gale. She was then making for the Bay of Biscay under all steam, but she was, as one of the men expressed it, “knocked about like a cork;" the heavy seas washed over her, and during the night two of the boats were carried away, and one man was washed overboard from the wheel. + At daybreak on Sunday morning it was reported from below that water was entering the engine-room, and as the ship appeared now in serious danger, efforts were made to lighten her by letting a portion of the cable run overboard; but the leakage still increased and by 10 o'clock it had extinguished the fires. The case then appearing hope- less, preparations were made with the boats to leave the ship. What followed had better be given in the words of the third engineer, one of the survivors. He said :- I was down in the engine-room in the morning when the water made its appearance. It rose so rapidly, that in a little while I was up to my waist, and the fires were extinguished. Then I went on deck, and the scene there was fearful. It was clear that the ship could not be saved; but Captain Dudden ordered all of us to keep to our duty, and to work the pumps to the last. We did, but it was of no use; the water got so high, that the ship began to settle down, and then there was a rush to the boats. It was dreadful to see the crew then. We had five boats to begin with; but two had been carried away during the night, and one had been stove in. Eleven others and myself jumped into one boat. There was Mr. Dicks, the chief engineer, standing by, and I begged of him to come with us. He said, "Oh, never mind me, old chap; it will be all right bye and bye." He would not come, though I begged and prayed of him to do so. At last I had to part with him, and I said, "If you are saved, and I am drowned, you'll carry a message to my wife, won't you?" He smiled, and said, “If I am drowned, and you are saved, you'll do the same by me." He was drowned, poor fellow, and so I have CHAP. VII.] 213 THE BRAZILIAN CABLE. to take his message. One of the foremen, who was on my watch had his son-in-law with him. When he saw that the ship was settling down, he said to his son-in-law, "George, my lad, here's a pretty thing!-there'll be our two widows in one house at home before morning!" This was terrible hard to bear, so I said to the old man, "Don't give up: trust to God, and our lives may be saved yet." It was awfully impressive to see how the poor chaps that could not get into the boats behaved; but the captain was as brave and cool as if nothing was the matter. had said he would not desert his ship, and he did not. down with her. Most of the officers did the same. In our boat we got on very well. ship until we were and round her. minutes to one. He He went We pulled away from the at a safe distance, and then we rowed round I saw her go down; that was at twenty-five She had been settling down some minutes, and then all at once she went down stern first. It was a fearful sight. She had burst her decks before foundering, and was in a terrible state. The captain was still at his post, looking quiet and calm, and I think he waved us a good-bye as the ship went down. There was a fearful screech from the men on board-such a cry as I hope I may never hear again. We picked up two boys and a man, but could not save any more. The other boat capsized before she was long in the water, and those who were in her were drowned. When we came to look at how we were fixed, we found that we had in our boat fifteen persons in all, and that we had nothing to eat except a Dutch cheese of about 6 lbs., a few biscuits, and a bottle containing a pint and a quarter of gin. One of the sailors, Thomas Clarkson, was appointed commander, and to him we owe our lives. He saved us from death by his skilful management. We could not tell where we were going, but allowed ourselves to drift on between the high waves that rose around us. It was a fearful night. I was on my knees all the while baling water out of the boat, and I wished I might be drowned, my sufferings were so terrible. Some of the others were even worse with fever and thirst. I used to hear them cry out "Oh my God, what would I not give for a drink of water!" There was plenty of sea-water, but they only drank that when they became reckless, and it made them mad. J 214 [CHAP. VII. ACTIVE BUSINESS. All through the night we were dashed about, and were saved God knows how; we saw a large steamer before us, and shouted with all the strength we could, but she could not hear us, and bore away. We had no lights, but she had, and that was the reason we could see her and she could not see us, so we had to go on as best we could till morning, and then, God be thanked, there came relief. We sighted a vessel right before us, and shouted like mad. We hoisted an oar with a handkerchief tied to it, and at last the ship discovered us. It was well she did, for most of us were at the last pinch, and were lying helpless at the bottom of the boat. The vessel was the Gare Loch, full of emigrants, and commanded by Captain Greenwood, one of the kindest and most Christian gentlemen I ever knew. He took us on board and first gave us a little water, then we had some brandy and water, then brandy, and after that some biscuit and soup. The emigrants, though they were very poor themselves, made a collection for us. Shortly after picking up the men the Gare Loch hailed the Antenor, one of the Ocean Steam-ship screw steamers, which was sailing from Gibraltar to England, and had herself suffered from the bad weather. The captain took the poor creatures on board, except one who was too ill to be moved, and they arrived in London on the 2nd of December. They described their sufferings as very severe, and some of them seemed bereft of reason. The descrip- tion given by the passengers of the Antenor, was said vividly to recall some of the most striking passages in Coleridge's Ancient Mariner, and there is no doubt that in those few days there was compressed a lifetime of horror. : The men saved by the Gare Loch were three engineers, two stewards, nine seamen and a boy. The news of the disaster, which thus reached London for the first time on the 2nd December, caused great excitement; and Messrs. Siemens took instant action. The catastrophe CHAP. VII.] THE BRAZILIAN CABLE. 215 had happened near Ushant, and they at once announced in the Times that they had telegraphed to Brest, and that a French Government steamer had gone out to search for survivors. They followed by sending out a personal agent, but on the 5th they reported that the steamer had returned to Brest unsuccessful. It was fortunate, however, that the locality of the wreck was just in the track of vessels going to and from the Channel, and three days after the foundering of the La Plata, two more of the crew, the boatswain, Lamont, and the quartermaster, Hooper, were picked up on a raft in the Bay. Their story, even more fearful and dramatic than that of the other men, was as follows: They were in one of the lost boats, and were washed into the water by a heavy sea; they had just risen to the surface when the ship took her final plunge, and they were drawn down again by the suction. After coming up the second time, they saw floating close to them one of the air-rafts, damaged, which they contrived to get hold of. This raft was made of indiarubber, in compart- ments filled with air and joined by a canvas band, forming a seat. Seated on this band, they were in a sort of trough, and the water came up to their waists, their bodies below getting gradually benumbed. Their only hope of escaping a lingering death lay in their being observed by some passing ship, and the chance seemed very small indeed, for to any ship not passing quite close they would have been only visible with a telescope when just on the crest of a wave. The sea was continually washing over them, and unless they had been men of strong vitality and sound physique, they could hardly have lived through the three days until their final rescue. During the Sunday, the first day of their suffering, they could only discover one passing ship, and she was much too far off to see them. On Monday there was a strong breeze, with a nasty sea, but the weather was fine. Several ships passed at a distance; but by none of them could they hope to be seen. Tuesday was calm during the greater part of the day, and their hopes were 216 [CHAP. VII. ACTIVE BUSINESS. raised by seeing a three-masted schooner passing within half a mile of them. They shouted with all their might, but the cry of distress was not heard, the speck on the wave was not seen, and the schooner sailed on. Towards Tuesday evening the breeze freshened, and it continued to blow hard during the night. The men were exhausted, and in the conflict between wearied nature and the hope of life they sank into a state between sleeping and waking, dozing for a minute or two, and then suddenly starting again into consciousness. About four on Wednesday morning, the one who was in his waking moments saw through the darkness the loom of a vessel bearing down upon them, and immediately roused his companion. The vessel rapidly approached, and came within 100 yards of them. With all the strength that was left in them they again put forth their cry for help, and after a few seconds' interval, a bright light told them that it had been heard. For two hours the light burnt like a beacon of safety before their eyes, but just before dawn it disappeared, and when day broke no ship was anywhere to be seen. Hope was fast giving way to despair, when about two hours after daylight the missing vessel bore down toward them. This was the Dutch schooner Wilhelm Blenkelszoon. The master, Captain J. van Dorp, when he heard the cry, had im- mediately brought his ship up, and lay-to till the morning. In the meantime the air-raft had drifted to leeward. When the Dutchman found at daybreak that nothing could be seen, he conjectured from the force and direction of the wind the point to which any floating wreck or boat would have drifted, and he hove down in that direction. But now another difficulty occurred. The sea was running so high that the master of the little schooner dared neither to lower a boat nor bring his vessel alongside. He feared that in the first case he might uselessly sacrifice his own men, and that in the last case his vessel would swamp the raft. He therefore beckoned to the two men to quit the raft and swim to the schooner. Thoroughly exhausted by their three days' exposure, they mis- trusted their powers of swimming even this short distance; but it was their only hope. Lamont, the boatswain, first made the attempt, and succeeded in getting alongside. Meantime the schooner and the raft had again separated, and the former made CHAP. VII.] 217 THE BRAZILIAN CABLE. another tack to give Hooper a chance. He was still more exhausted than Lamont, but thinking it was no worse to be drowned between the raft and the ship than be left to perish on the raft, he made the desperate effort, and struck out for the schooner. But when he got alongside his hands were too benumbed even to clutch the rope held out to him, and he took it between his teeth. The little schooner was low in the water, and some of the crew leaning over and watching their opportunity, caught him by the hands and pulled him on board. The men were unable to stand, and almost dead from exposure and want of food, for it was then close upon noon on Wednesday, and they had eaten nothing since the previous Saturday evening. But they were brought round by the kindness and tender care of Captain van Dorp and his crew, which were such as to merit the highest praise. They were taken to the Civil Hospital at Gibraltar, when they were conveyed to Southampton by the P. and O. steamer Cathay, arriving there on the 24th December. Their names had been published as among those who perished; and they must have been considered by their families as having risen from the dead. The number saved was thus increased to seventeen. The number lost were fifty-eight, among whom were the captain, the surgeon, three officers, and the whole of Messrs. Siemens's cable staff, including the chief of the expedition, Mr. Ricketts, and six skilled assistants accom- panying him. The disaster caused some public excitement; and it was difficult to understand. Gales in the Bay of Biscay were common enough, but they were usually weathered safely by good and well-managed ships, and the question arose whether anything could have been amiss with the La Plata. It was just at the time of Mr. Plimsoll's well-known agita- tion; this increased the uneasiness, and reports were even circulated to the prejudice of the owners and charterers, that the vessel had been noticed to be improperly laden as 218 [CHAP. VII. ACTIVE BUSINESS. she passed down the Thames. These reports were imme- diately enquired into by the Board of Trade at the instance of Messrs. Siemens, and were publicly proved to be without the slightest foundation. But this was not enough; it was necessary, as a public measure, that the usual official en- quiry should be made into the circumstances and causes of the catastrophe, and this was encouraged by the parties interested, who undertook to give every help in their power. The enquiry took place under the auspices of the Board of Trade shortly afterwards. It was held publicly at Greenwich, by Mr. Balguy, a police magistrate, assisted by Captain Oates and Captain Pryce, as nautical assessors, and by Mr. Traill, chief surveyor of the Board of Trade, as engineering assessor; and all parties interested were repre- sented before the Court. The investigation began on the 19th of January and lasted for 11 days. The evidence was taken of all the best men among the survivors, as well as of other persons connected with the ship, and of several professional nautical experts. Dr. Siemens was examined and gave full explanations as to the part taken by his firm in the provision and fitting out of the ship, and the arrangement of her lading, which had all been done under the direction and to the perfect satis- faction of the captain and his officers. He said he had voluntarily increased the means of safety and comfort;— he had provided an extra life-boat, and had added two life- rafts, and Mr. Ricketts had taken out a third as an experi- He had also increased the number of the crew, and added a doctor, and in short he had done all in his power to make the expedition safe and successful. ment. The Report was issued the beginning of March. Mr. Balguy gave his opinion— CHAP. VII.] 219 THE BRAZILIAN CABLE (1.) That the La Plata, when she left Gravesend, was a strong ship, and in a seaworthy condition. (2.) She was not overladen, and her cargo was properly stowed. (3.) She was in proper trim. The Assessors differed from the magistrate in some par- ticulars and made a separate report. They said :— (1.) We have come to the conclusion that the La Plata was in every way seaworthy when she left the Thames, so far as her hull, machinery, and equipment were concerned; we think therefore that both owners and charterers ought to be exonerated on that score; also so far as Messrs, Siemens & Co. were concerned, these gentlemen, as an act of forethought and humanity, actually supplied three life-rafts and forty life-belts at their own expense in the event of a casualty arising when they might have been of service. (2.) We are decidedly of opinion that the La Plata was not overloaded, but we do think that the trim of 4ft. 6in. by the stern when loaded would be liable to increase her danger under certain contingencies, such as running before a violent gale or being pressed against a heavy head-sea. We are of opinion that a trim of 3ft. 6in. by the stern would have been more prudent, and would have covered all the difficulties raised by the evidence. It will be seen, therefore, that all the judges agreed in exonerating Messrs. Siemens from blame; for in regard to the trim, in which they differed, it was clearly stated in evidence that Messrs. Siemens had no control over it, but that it was determined entirely by the captain of the vessel. The immediate cause of the disaster was judged to be the entrance of water into the engine-room; it was at first thought that a leak arose from some damage to the hull when the boat-davits were carried away, but this was dis- proved. No sufficient cause for the leakage could be shown, and there was reason to believe that it arose from some derangement of the water-passages connected with the engine, which it was quite within the power of the 220 [CHAP. VII. ACTIVE BUSINESS. " engineers to control. The magistrate, therefore, expressed his opinion"that the disaster originated in the stoke hole; -the assessors, going into more detail, agreed that there was "gross negligence in the engine-room department, and they also attributed mismanagement to the captain. The evidence, however, was conflicting, and many of the facts were obscure. The Queen manifested the deepest sympathy for the sufferers, and directed special enquiries to be made after the widow of Captain Dudden, who, it was reported, behaved with the greatest courage. Besides providing for the widows and families of the principal members of their own staff who had been lost, Messrs. Siemens gave £500 to the public fund raised in aid of the widows and orphans of the men lost in the ship. Similar sums were given by Mr. Henley and by Messrs. Grant Bros. (from whom the contract for the cable was obtained), and the total of the fund was raised to about £4650, which was distributed by a committee formed principally of officials of Messrs. Siemens and Mr. Henley. Among the assistants drowned was Mr. David King, son of the Rev. David King (of Glasgow, and afterwards of London), and nephew of Sir William Thomson. The following letter was from his brother:- C. W. SIEMENS, ESQ., F.R.S. MY DEAR SIR, 40, BARK PLACE, BAYSWATER, March 24, 1875. I have called at your house several times in order to thank you personally and on behalf of my father and mother for all you did in trying to rescue those lost in the La Plata. I have, however, been unfortunate in always finding you from home, and rather than put off longer, I resort to the much less satisfactory CHAP. VII.] 221 THE BRAZILIAN CABLE. method of writing. Although your efforts were unavailing to save us from a very heavy bereavement, you none the less have our most heartfelt gratitude. * * * * * Hoping that both yourself and Mrs. Siemens are well, I remain, yours faithfully, GEO. KING. Another letter, from a friend of one of the sufferers, may also be given to show that the sympathy of Dr. Siemens was duly appreciated. MY DEAR SIR, April 7, 1875. On behalf of the brother and sister, and on my own behalf, accept the best thanks that grateful hearts can offer for your generous help in the past, and your most kind promise in the future. It has already added greatly to the comfort of those who have had a very heavy burden to bear, and it will materially add to the happiness of the survivors. Might I suggest that it would save you some trouble if you thought well to give your banker instructions to pay your very kind contribution to my credit with Messrs. in future? Your present, cheque will enable them to meet necessary expenses and give them a few days at the sea-side, so you may judge what reason they have to bless you. C. W. SIEMENS, ESQ. Dr. Siemens felt this calamity very deeply: it aged him perceptibly, and its effects on him were visible for years afterwards. Indeed, it is doubtful whether he ever re- gained the bright buoyant spirits he had before the catastrophe. In February, 1875, a third ship, the Ambassador, was sent out, and successfully completed the enterprise of laying the Brazilian cable. 222 [CHAP. VII. ACTIVE BUSINESS. It may be mentioned, in connection with this work, that in 1871, the Emperor of the Brazils had visited England. He took much interest in the scientific and mechanical institutions of the country, and he inspected many of the most important manufactories. Dr. Siemens was intro- duced to His Majesty in July, 1871, and took him to see the works at Charlton, showing him the whole operations of the manufacture. The Emperor did not forget this, for it led to Dr. Siemens's receiving afterwards the following letter:- SIR, BRAZILIAN LEGATION, LONDON, March 29, 1873. I have the honour to inclose herewith the Imperial letter by which His Majesty the Emperor of Brazil, my august Sovereign, has been graciously pleased to appoint you a Com- mander of His Imperial Order of the Rose. Permit me to avail myself of this opportunity to offer you my sincere congratulations and the assurance of my highest considera- tion. C. WILLIAM SIEMENS, ESQ. PEREIRA DE Andrada. P.S.-The respective Insignia will be forwarded to you as soon as it may be possible. "" After the telegraphs were laid His Majesty conferred a further honour on Dr. Siemens, creating him a "Dignitario of the same Order, in February, 1876. French Atlantic Cable. In 1879, the firm made and laid a second Atlantic cable, from Brest, via St. Pierre Miguelon, to Cape Cod in Mas- sachusetts, about 2250 nautical miles long. This was for the Compagnie Française du Telegraphe de Paris à New York. Many pourparlers had taken place CHAP. VII.] 223 ELECTRIC LIGHTING. previously, even as early as 1876, about a proposed cable; but when at length it was decided on, the parties were in a great hurry to have it finished, and the most remarkable feature of the contract undertaken by Messrs. Siemens was the short time in which it was completed. The order was given by the French company in March, 1879. The manufacture of the cable was finished by the 18th June, when the Faraday left Woolwich with it on board, for the laying, under the charge of Mr. Loeffler ; and the main cable was handed over to the proprietors, in perfect working order, on the 26th October, 1879. ELECTRIC LIGHTING AND POWER. It was during this period that the firm of Siemens. Brothers took up what ultimately became a very large branch of their business, namely, the manufacture of appa- ratus for producing and utilizing the more powerful effects of electricity. The telegraph work, important and difficult as it was, particularly in its submarine circuits, involved only slight electrical action, generated by batteries of comparatively small power, with currents travelling along wires of very minute diameter, and with only just energy enough to give movement to delicately poised needles. The invention lay in so guiding and conducting this faint power as to render its application certain and convenient in use; the produc- tion of great motive force formed no part of the need, and the batteries, though the sources of action, constituted gene- rally only a subordinate part of the consideration. As the scientific and practical acquaintance with this "great power in Nature" advanced, it was seen that new and highly advantageous applications of it were possible, which required as their essential element great accumu- 224 [CHAP. VII. ACTIVE BUSINESS. lations of the electric energy; and the carrying out of these into industrial practice gave rise to problems of altogether a new kind. The chief practical novelty was electric lighting, which required provisions of the acting force of a magnitude altogether beyond the small means used in telegraphy, and of a nature to require new modes of production. In the development of these the brothers Siemens took a very important and prominent share, and it may, therefore, be interesting to give here a brief abstract of the chief facts relating to the change. The appreciation of the powerful physical effects producible by the electric current must have been coeval with the discovery of electricity itself, or at least with the time when its identification with the natural phenomena of a thunderstorm was proved. In particular, the brilliancy of its light was implied in the word "light- ning," and the "spark" of the first artificial discharge was an "electric light" in the truest sense. But the duration of the light produced in this way was almost infinitesimally short. Powerful and brilliant indeed it was, the flash illuminating objects to a degree far beyond that of any artificial light known; but a light enduring but a fraction of a second was of little use to anybody. It was only when Volta, in 1800, made his immortal discovery of the pile, producing a steady flowing permanent current of electricity, that any hope of utility could be obtained. As soon as this discovery was taken up by scientific men, both the light and the heat obtainable by the Voltaic circuit attracted marked attention. A Mr. Children, with a CHAP. VII.] 225 FARADAY'S DISCOVERIES. battery exceeding in strength all its predecessors, fused platinum wires 18 inches long, while points of charcoal produced a light "so vivid that the sunshine compared with it appeared feeble." Such effects reached their cul- mination when, in 1808, Davy produced at the Royal Institution, with a battery of 2000 pairs of plates, calorific and luminous effects far transcending anything previously observed. Here, therefore, was the electric light in full existence. nearly three quarters of a century ago. Its applications to practical purposes suggested themselves at the outset. The mechanical arrangements offered no great difficulty; but the obstacle to the use of the light was the great cost of producing the current. The zinc was too expensive a fuel to be generally used, and hence the electric light as given by the Voltaic battery was little more than a philosophical toy. The step which altered this state of things was made. by Faraday, who, in 1831,* pointed out a new source for the electric current in the action of magnetism. It had already been observed that there were some rela- tions between magnetism and electricity. In 1820 Oersted remarked that an electric current would deflect a magnetic needle; and in the same year Arago discovered that an electric current could impart magnetic properties to a bar of iron or steel. Here was electricity producing magnetism; but there had been no evidence of the converse effect, i.e., of magnetism producing electricity; and so far as we know there had been no suspicion that such an effect was possible, in any mind save one-that of Faraday. * Paper read before the Royal Society, November 24, 1831, and published in the Philosophical Transactions. Q 226 [CHAP. VII. ACTIVE BUSINESS. His wonderful intuitive perception of philosophical truths told him that this ought to be. He said at a later time, describing his earlier views:- It appeared very extraordinary that, as every electric current was accompanied by a corresponding intensity of magnetic action at right angles to the current, good conductors of electricity when placed within the sphere of this action should not have any current induced through them, or some sensible equivalent in force to such a current. These considerations, with their consequence, the hope of obtaining electricity from ordinary magnetism, have stimulated me at various times to investigate experimentally the inductive effect of electric currents. I lately arrived at positive results, and had my hopes fulfilled. Dr. Siemens stated, no doubt on personal information given him, that Faraday had formed his expectation as early as 1824, judging by à priori reasoning, but that seven years elapsed before he could detect the truth of his prophecy with the instruments then at his command. His paper of 1831, now become classical, was divided into four sections; the one which contained the discovery was entitled "Evolution of Electricity from Magnetism." It contained descriptions of many experiments all bearing on the subject; but it will suffice here to mention two, which gave the results in the most striking form. In paragraph thirty-nine he showed that when a per- manent bar magnet was suddenly inserted into the centre of a cylindrical coil of insulated wire, it caused a cur- rent to circulate in the wire. But this effect was only momentary; that is, it lasted just as long as the magnet was in motion within the coil, and ceased when the motion ceased. When the magnet bar was suddenly withdrawn from the coil, another current was set up in the wire, its direction being the reverse of the former one. In this CHAP. VII.] 227 FARADAY'S DISCOVERIES. case, also, the current was only produced while the magnet was in motion. The effects were not great, but they could be increased by accumulated action on the repetition of the motions. In paragraph thirty-six, Faraday described a somewhat different experiment, but still tending in the same direction. He formed an armature to a horse-shoe magnet by a bar of soft iron, part of which was covered with a coil of copper insulated wire. When he forcibly broke the contact between the armature and the magnet, a current was momentarily set up in the wire, but it stopped when the armature was at rest. When he re-made the contact, another momentary current was similarly set up in a contrary direction. The effects produced were feeble, but they were quite positive and characteristic, and Faraday remarked :- The various experiments of this section prove, I think, most completely the production of electricity from ordinary magnetism. That its intensity should be very feeble and quantity small cannot be considered wonderful, when it is remembered that like thermo- electricity it is evolved entirely within the substance of metals retaining all their conducting power. But an agent which is conducted along metallic wires in the manner described, which, whilst so passing possesses the peculiar magnetic actions and force of a current of electricity; which can agitate and convulse the limbs of a frog, and which, finally, can produce a spark by its discharge, can only be electricity. The similarity of action, almost amounting to identity, between common magnets and either electro-magnets or volta-electric currents . . . furnishes powerful reasons for believing that thy action is the same in both cases; but as a distinction in language is still necessary, I propose to call the agency thus exerted by ordinary magnets, magneto-electric or magnelectric induction. In giving a public account of Faraday's discovery, Dr. Siemens, with his usual partiality for illustrating general natural laws, took hold of the fact that the pro- Q 2 228 [CHAP. VII. ACTIVE BUSINESS, duction of the electric currents in each case was con- comitant and correlative with the expenditure of mechanical force. In thrusting the bar magnet into the centre of the coil, or in withdrawing it therefrom, a resistance was encountered analogous to that felt when a piece of iron was manipulated near a magnet. And in the other case of the severance of the armature from the magnet, Dr. Siemens remarked that the current produced thereby was the direct outcome of the mechanical force used to detach the armature. He also explained that the single current resulting from the forcible severance of an armature from its magnet was capable, if diverted through the coils of another armature in contact with its own magnet, of effecting the severance of this second armature; and that the force originally expended in severing the first armature bore a definite relation to that applied to moving the second armature. Hence in viewing this experiment by the light of the principle of the "conservation of energy," and the "cor- relation of forces," it was demonstrated that mechanical force could be converted into electric current, and that electric current could be converted back into mechanical force, at pleasure; the quantitative relations between the two being, moreover, capable of exact definition. This simple fact formed the foundation of the whole of the splendid development of dynamic electricity which has taken place of late years. Accordingly, now, when more ample provisions of electric agency were demanded than could be furnished by Volta's chemical changes, they were sought in Faraday's appli- cation of mechanical power. This was obtainable, from various quarters, such as muscular action, water, or steam, in any required amounts, at a very cheap cost; and all that was wanted was to invent, and to bring into practical CHAP. VII.] 229 FARADAY'S DISCOVERIES. and useful shape, the means for its conversion into corres- ponding large quantities of electricity. The currents produced by Faraday were, as he himself remarked, very feeble, and only instantaneous in their action. But it was clear that this apparent disadvantage could be easily remedied; for by repeating the mechanical actions by suitable arrangements, a rapid succession, and a consequent aggregation of these currents could be pro- duced so that if these were sent continuously through a metallic conductor, all the phenomena of a continuous current would be obtainable, with the condition also of ¡reat magnitude and power. Dr. Siemens illustrated this very aptly by saying:- : The single current revealed by Faraday's original experiment might be likened to the single drop of rain, which, though im- puissant by itself, was, when repeated often enough in its fall on an elevated plateau, capable of giving rise to streamlets and streams, until at last a mighty river, and a source of power, such as the Falls of Niagara, might be produced. When Dr. Siemens lectured at the Institution of Civil Engineers in 1883 (a few months before his death), on the electrical transmission of power, he exhibited the identical original magnet and coil that Faraday had used in 1831, when communicating his discovery to the audience at the Royal Institution. He said :- When Faraday saw the spark [indicating the production of the electric current], and was able to show it to his audience, it was a red-letter day in his existence, and he even then thought it would be a point of departure of some importance, because he said on that occasion, "Although this spark is very small, so that you can hardly perceive it, others will follow who will make this power available for very important purposes." And so it has indeed proved. 230 [CHAP. VII. ACTIVE BUSINESS. No sooner was Faraday's discovery published than many attempts were made to magnify his induced currents so as to bring them into practical use. Faraday had foreseen that such attempts would be made, but he chose to leave them in the hands of the mechanician. He wrote in 1831: "I have rather been desirous of discovering new facts and new relations dependent on magneto-electric induction, than of exalting the force of those already obtained; being assured that the latter would find their full develop- ment hereafter." The utilization of the induced current, was, however, a work of much time and thought on the part of those who followed in the wake of the great discoverer. The develop- ment was aimed at by Pixii, Clarke, Saxton and others, who caused magnets to rotate near coils of wire, or coils of wire surrounding iron cores to rotate near the poles of powerful steel magnets. The presence of the iron cores, as shown by Faraday, greatly intensified the action. The invention was chiefly used for telegraphic work, one of the most practical applications being made by Wheat- stone in 1844, when he brought out his magneto-electric step-by-step instrument. But, notwithstanding the great ingenuity displayed in its design and construction, the current induced was found practically insufficient to produce the effect desired. The first successful application of the magneto-electric machine in a powerful form was for lighting; and this came about in rather a curious indirect way. There had been a great stir about the Drummond light, pro- duced by burning oxygen and hydrogen on lime. Many inventors had tried to obtain it cheaply, and in 1853, Nollet, a clever mechanician, constructed a powerful mag- neto-electric machine to produce the gases by the decom- CHAP. VII.] 231 SIEMENS'S ARMATURE. position of water. The experiment failed, but the machine was seized upon by Professor Holmes, who tried to apply its current directly to the production of light. He worked perseveringly some years, improving it and augmenting its power, till it was finally able to yield a light equal to that of the voltaic battery; and on the 8th of December, 1858, the electric light was experimentally shown on the sea, for the first time, from the Lighthouse on the South Foreland. But in the meantime the Siemens's had entered on the field of labour. An important step towards aggre- gating magneto-electric currents was made in 1856 by Dr. Werner Siemens, who constructed an armature resembling in section the letter H, into the hollows of which the insulated wires were wound longitudinally. It was then mounted on bearings so as to be able to rotate about its longitudinal axis, and was placed between the north and south poles of a number of permanent horse-shoe magnets, ranged in a line. When, therefore, a rapid rotation was given to the armature an accumulative effect was produced through the simultaneous action of each permanent magnet in generating a current in one and the same coil; thus a succession of currents was set up, which when directed by means of a commutator" into an outer metallic circuit, furnished a continuous current of considerable power. (6 This was a very valuable invention, for on account of the small space that it occupied in revolving, it could be kept in an intense magnetic field produced by small magnets; and its cylindrical form was eminently adapted for rapid rotation. This armature was adopted and largely used by Siemens and Halske in their magneto-electric machines, particularly in one which they called a Zeiger, an alphabetical indicat- 232 [CHAP. VII. ACTIVE BUSINESS. ing instrument. In 1865 it happened that a machine of some kind, in which this armature was used, was being prepared by the firm for exhibition in Paris, and Werner in experimenting with it was struck with its great capa- bility. He said, in a letter to William (probably about the middle of that year, the exact date is lost) :- I have been for some days occupied with the trials of the large dynamo-electric inductor. I must lay down a special foundation for it, for it cannot be fixed firmly enough in the workshop. It appears to effect its object, but our engine is too weak to exhibit its full power. It is a pity that it goes to Paris too late for the visit of the potentates, but I will send it off in a week, and rely on your help for its exhibition. There must be a special steam-engine allotted to it in the Prussian department. It is remarkable what a great power is required fully to develop the electric current ! When the merits of this improvement became known, it was made use of to further the solution of the problem of lighthouse illumination. Following up the experiment at the South Foreland in 1858, the Trinity House consulted Faraday, who encouraged them to proceed. Professor Holmes gladly availed himself of the Siemens armature, and, persevering in his own efforts to improve his machine, he attained such success that in June, 1862, the electric light was permanently established at Dungeness, where it shone for thirteen years. Further lights were afterwards established at South Point in 1871, at the South Foreland in 1873, and in several places abroad. In 1866 another inventor, Mr. Wilde, of Manchester, took advantage of the Siemens invention to construct a very powerful apparatus. He used a Siemens permanent- magnet machine to furnish the current to excite the electric magnets of a larger one, also constructed with a Siemens armature, the smaller machine being provided CHAP. VII.] THE SIEMENS DISCOVERY. 233 with a commutator, so as to give a current of constant direction. Both Wilde's and Holmes's machines marked a farther step forward, by the adaptation of steam power to work them. Their capabilities had reached so far that the force necessary to excite and accumulate the currents was more than hand labour could supply, and the substitution of mechanical working at once gave increased power and greater economy. But now came out the great discovery by the brothers Siemens, alluded to on page 180, namely, the principle of electro-magnetic augmentation and maintenance of a current without the aid of steel or other permanent magnets. The first mention of this appears to have been in a letter from Werner to William, dated 4th December, 1866. He said- I have had a new idea, which, in all probability, will succeed, and will give important results. As you well know, Wilde has taken a patent in England con- sisting in the combination of a magnet-inductor of my construction with a second one which has a large electro-magnet instead of the steel magnet. The magnet-inductor as constructed in our alpha- betical telegraph instruments magnetises the electro-magnet to a higher degree than can be obtained by steel magnets. The second inductor will therefore give much more powerful currents than if it had steel magnets. The action ought to be colossal, as is stated in Dingler's Journal. But now, clearly, the magnet-inductor with steel magnets may be entirely dispensed with. If we take an electro-magnetic machine, which is so constructed that the stationary magnet is an electro-magnet with a constant polar direction, while the current of the moveable magnet is changed; and if we insert a small battery which will thus work the apparatus, and now turn the machine in the contrary direction, the current must increase. The battery may be excluded and removed, without stopping the 234 [CHAP. VII. ACTIVE BUSINESS. action. It is, in other words, a Holz's machine, used for electro- magnetism. We may thereby, with the sole aid of wire-coilings and soft iron, transform power into current, if only the impulse is given. This giving of the impulse, which determines the direction of the current, may also be effected by the magnetism which remains behind, or by a pair of steel magnets which continually give to the nucleus a slight magnetism. The effect must, with a proper construction, be colossal. The thing is very capable of development, and may form a new era in magneto-electricity. In a few days an apparatus will be ready. Magneto-electricity will by this means become cheap, and electric-lighting, galvano-metallurgy, and even small electro-mag- netic machines, receiving their power from larger ones, may become possible, and useful. It appears that previously to this* William and his brother had been engaged in a discussion as to the dyna- mical principle of the convertibility of natural forces, and probably the experiments mentioned by Werner may have been prompted by this discussion. At any rate William immediately appreciated the importance of the discovery, and he determined to go over to Berlin and see the expe- riments for himself. He accordingly left London on the 15th December, arriving at Berlin on the 19th. The two brothers then carried on further trials together, and these were so satisfactory that Werner invited Professors Dove, Magnus, Du Bois-Reymond, and several other of the leading physicists of Berlin to witness the experiments. This inspection took place before Christmas, 1866. There was thus no doubt of the value of this discovery, both in a scientific and in a practical point of view. It was decided that as a scientific matter it should be laid * See letter from Mr. Wm. Siemens, published in Engineering, November 2, 1877. CHAP. VII.] THE SIEMENS DISCOVERY. 235 before the Academy of Berlin and the Royal Society of London, while to carry out its practical advantages, William should protect it by an English patent. He returned to London early in January, and on the 15th of that month Werner wrote to him further as follows:- The description of the new electro-dynamic inductor for the Royal Society shall be sent you to-morrow. On Thursday Magnus will bring it forward in the Academy. It is successful beyond expectation, even in small dimensions. By it the question of exploders (for mines and quarries) is already practically solved. It will be a most important thing. A man can hardly turn by force an inductor of quite small size as used in our alphabetical instruments if it is closed without resistance. On the 17th he wrote:- I now send you a press copy of the notice read in the Academy. The thing will really be very important. The little apparatus, the size of a small armature as used in the Zeiger, when given only one turn of the crank, sets itself, by the weak remaining magnetism, when the coils are short circuited, in such strong activity, that the crank can only be moved further with difficulty. If, after one turn, the short circuit is interrupted mechanically, we get, in a circuit of greater resistance, such strong currents that six English cartridges can be fired with certainty. The question of exploding cartridges is thereby perfectly disposed of. On the 2nd February he again wrote:— The alteration in the great inductor lately communicated to you has produced but little change. Although now not the least friction is present, a considerable power is due to the turning of the inductor, and the magnet armature quickly becomes warm, i.e., the iron, not the wires. The current does not become so strong as to heat these, because the machine, when short circuited, either stops still, or makes the driving-bands slip on their pulleys. 236 [CHAP. VII. ACTIVE BUSINESS. The armature is turned three to four times per second, and this gives a current which will make an iron wire, eighteen inches long and one millimetre thick, bright red hot. On the 13th February he further said :— The action is remarkably striking, even with small machines. When open we can turn without perceptible resistance, but when closed, the resistance increases after a few turns to the limit of possibility. If then the short current is suddenly interrupted, we get, in a large field, a very lively spark, which is suitable for exploding. He described many useful applications he had in view. The communication to the Royal Society was made by William on the 4th February, and was read at the meeting on 14th February, 1867. It formed the now classical paper "On the conversion of Dynamical into Electrical force without the aid of Permanent Magnetism." The author said:- Since the great discovery of magnetic electricity by Faraday in 1830, electricians have had recourse to mechanical force for the production of their most powerful effects; but the power of the magneto-electrical machine seems to depend in an equal measure upon the force expended, on the one hand, and upon permanent magnetism on the other. "An experiment, however, has been lately suggested to me by my brother, Dr. Werner Siemens, of Berlin, which proves that permanent magnetism is not requisite in order to convert mechanical into electrical force; and the result obtained by this experiment is remarkable, not only because it demonstrates this hitherto unrecognised fact, but also because it provides a simple means of producing very powerful electrical effects." He then gave a description of the simple electrical arrangement employed, which was a modification of the original Siemens armature; and he exhibited a machine in CHAP. VII.] THE SIEMENS DISCOVERY. 237 which it was carried out. In describing its action he said: "On imparting rotation to the armature of such an arrangement, the mechanical resistance is found to increase rapidly, to such an extent that either the driving-strap commences to slip, or the insulated wires, constituting the coils, are heated to the extent of igniting their silk covering. It is thus possible to produce mechanically the most powerful electrical or calorific effects without the aid of steel magnets, which are open to the objection of losing their permanent magnetism in use." It is singular that the same idea occurred about the same time to two other eminent electricians-Professor Wheatstone and Mr. Alfred Varley. Professor Wheatstone communicated it to the meeting of the Royal Society on the same day as Mr. Siemens, and Mr. Varley had in the previous December applied for a patent, depositing a “pro- visional specification"—a sealed document-in which it was embodied. In fact, the discovery seems to have been, as the saying is, "in the air;" and there is no good reason to impugn the honesty of the claim of each of the three parties to its independent discovery.* Many letters on this subject will be found in Engineering for October and November, 1877. The patent for the invention was dated 31st January, * Dr. Tyndall, in his lecture on the electric light at the Royal Institution, January 17, 1879, makes the following remarks on this point :- "A paper on the same subject by Dr. Werner Siemens was read on the 17th of January, 1867, before the Academy of Sciences in Berlin. In a letter to Engineering, No. 622, p. 45, Mr. Robert Sabine states that Professor Wheatstone's machine was constructed by Mr. Stroh in the months of July and August, 1866. I do not doubt Mr. Sabine's statement; still it would be dangerous in the highest degree to depart from the canon, in asserting which Faraday was specially strenuous, that the date of a discovery is the date of its publication." 238 [CHAP. VII. ACTIVE BUSINESS. 1867 (No. 261), and was fully specified in due course. The title was for- Improved methods for developing powerful electrical currents and discharges, principally applicable to the production of lights at sea, and in apparatus for determining electrical resistances in connection with such and other currents. (Partly a communi- cation from Werner Siemens, of Berlin.) The nature of the invention was thus described in the first claim :- Developing powerful electric currents in electro-magnetic ap- paratus by causing the poles of a rotating electro-magnet or keeper to be forcibly approached successively to the similar poles, and forcibly severed from the dissimilar poles of stationary electro-magnets or coils, the currents being directed by means of a commutator or of current-changers, so as to produce the above effect, and thereby cause an accumulation of magnetism and of the currents produced by the apparatus. The application to marine lights is mentioned as follows:- • Lighthouses have in some cases been illuminated by means of electric lamps. . . As the powerful batteries, such as would be requisite for these electric lamps, are exceedingly perishable and expensive to maintain, magneto-electrical machines have been employed for producing the requisite electric currents; but even these machines are apt to lose their efficiency, owing to a gradual decrease of the permanent magnetism of the steel bars employed. The present invention consists, firstly in obtaining powerful electric currents without the aid either of large batteries or of permanent magnets by the following method. This method is then described, and the patent also goes on to state how lights may be transmitted through wires to lights, beacons, and buoys out at sea. Such was the great discovery; the abolition of perma- nent or steel magnets, and the substitution of electro- CHAP. VII.] THE SIEMENS DISCOVERY. 239 magnets excited by the current produced by the rotation. of the helix or armature of the machine itself. Considering the great importance of this invention as bearing on the applications of electricity on a large scale, it may be well to explain its nature and advantages somewhat more fully. The machines which induced their electric currents from "permanent" magnets had several drawbacks. In the first place, their power was limited by the comparatively feeble intensity of magnetization of the steel magnets, which was, at the best, far inferior to that of electro magnets; and, further, the so-called "permanence" of magnetization was only a name, all steel magnets losing a percentage of their magnetism every year. Hence it followed that the power of a machine depending on their inductive influence must be continually diminishing, until the magnets had to be renewed or re-magnetized. Moreover, as Werner Siemens truly pointed out, the effect of the machines did not increase with their dimensions; to get great power it would be necessary to use disproportionately large masses of iron, steel, and wire, and the machine would become too cum- brous and costly. The new discovery of the "reaction principle of magneti- zation" consisted essentially of using the residual or inhe- rent magnetism of the iron coil of the electro magnet (and which all iron possesses more or less) for inducing in the coils of the revolving armature a feeble current, which, by being carried round the coils of the original magnets, was sufficient, feeble as it was, slightly to increase their magnetic intensity. This increase of magnetism reacted on the coils of the armature, producing a still stronger current, which, in its turn, again increased the intensity of the electro- magnets. Action and reaction thus went on between the electro magnets and the armature, until, in a few seconds, the magnets were charged to their point of saturation. With 240 [CHAP. VII. ACTIVE BUSINESS. this arrangement a moderate-sized machine would produce, through the accumulation action, effects of great magnitude, strictly proportionate to the mechanical power employed. Werner Siemens proposed to apply the term magneto- electric to machines in which the original steel magnets were used, and dynamo-electric to those where the current was produced by power alone; a nomenclature which is come into general use. The immediate result of this discovery was the produc- tion of one of the most wonderful of modern instruments, the DYNAMO-ELECTRIC MACHINE, or as it is now more briefly called the Dynamo. It is, as its name (combining the word dúvaμis, power) implies, an instrument which is founded on the relations between power and electricity. If mechanical agency be applied to it in the form of muscular force, or water or steam power, the machine will convert this into its proper equivalent (minus certain necessary losses) of energy in the shape of an electric current; or, by a reverse operation, if an electric current be introduced into it, it may be changed into a corresponding equivalent of mechanical power, which will do work that might be done by muscles, or by water, or by steam. The Berlin firm endeavoured, without loss of time, to put the new invention to practical use for the purpose of lighting. In a letter from Werner to William, dated 10th July, 1868, he said :— This evening we shall make further lighting experiments with the dynamo-electric machine in the artillery practising ground. With the last trials the apparatus illuminated a target at 2500 paces distance so clearly that it could be aimed at with muskets, and was struck by nine shots out of ten. To-night we shall fire with big guns at an object electrically illuminated. We shall also try the electrical distance-measurer, which promises well. CHAP. VII.] THE HEFNER-ALTENECK MACHINE. 241 In England also Mr. Holmes, at the instance of the Trinity House, endeavoured to turn the new discovery to account for the illumination of lighthouses. In the spring of 1869 he had constructed a machine which exhibited extraordinary power, and produced a light of great splen- dour. But it was still hampered by defects, and, as a matter of safety, the magneto-electric machine was still adhered to for lighthouse purposes. In 1872 Dr. Siemens brought out some improvements, communicated by Werner, having to do with the arrange- ment and motions of "coils suspended in a magnetic field." But a much more important invention was patented a year afterwards, June 5, 1873. This was entitled, Improvements in Apparatus for producing and regulating electric currents, such apparatus being particularly appli- cable to electric lighting." 66 It was stated to be " a communication from Dr. Werner Siemens, and Friedrich von Hefner-Alteneck." The latter named gentleman, who is a well-known scientific engineer in Berlin, appears to have had the chief share in the invention; and the machine, as subsequently made, was called indiscriminately either the "New Siemens," or the "Hefner-Alteneck" machine. The object of the invention was to increase the power and capability of the dynamo, by a skilful combination of several elements, founded on the original Siemens invention. It has been briefly described as a "suggestion for the mode of connexion between the coils of a multiple-coil Siemens armature." The principal claim of the patent is for- The use of apparatus for producing electric currents by the application of mechanical force, in which apparatus a shell coiled R 242 [CHAP. VII. ACTIVE BUSINESS. longitudinally with insulating conducting wires on its outside is made to revolve in the annular space between fixed external magnetic poles or polar extensions and a fixed internal cylinder of iron, which may be independently magnetized. * This invention completed the essential structure of the Siemens dynamo-electric apparatus, and it has been well remarked by a high authority that the evolution of this splendid machine from their rudimentary armature of a quarter of a century ago is one of the most beautiful pro- ducts of inventive genius, and is more like to the growth of a flower than to almost anything else in the way of mechanism made by man. In this notice we have mentioned only the forms of dynamo with which Messrs. Siemens have had to do; but many other forms of the machine for producing large electric currents have been contrived by other inventors and manufacturers, some of them of high merit, and much used. Among these are those of M. Gramme, the Brush Company, the Gulcher, the Crompton, the Gordon, the Edison, the Hopkinson, the Sawyer, and many others. Such is the dynamo-electric machine. Its chief applica- tion is to electric lighting, which may be now briefly explained. The production of the light depends on some local resistance offered to the passage of the electric current at a given point of its circuit, the effect of which is to expend the energy in the production of light and heat. The light is produced, for practical purposes, in two ways. In the first place, Davy showed in 1810 that the greatest local resistance, and the highest degree of heat and luminosity, * Sir William Thomson, “Nature," Nov. 29, 1883. CHAP. VII.] 243 ELECTRIC LAMPS. were produced when the electric current passed between two carbon points. When these are placed a short distance apart, the current will cross the space; but as the air is a bad conductor, the break so formed offers great resist- ance to the passage of the current, great heat is produced, and a luminous band of light, of great brilliancy, is formed there. The light is caused partly by the incandescence of the carbon points themselves, and partly by the volati- lization of a small portion of the carbon, which flies across in the state of intensely heated vapour. This luminous band, from its sometimes assuming a curved form, is called the Voltaic Arc; and lights formed on this principle are called Arc lights. The carbons must be made to keep their points at the required distance apart, and as they become consumed, they are usually made to approach each other by clock- work machinery. But the regulation of the electric arc to meet the varying conditions of the current and the carbons, has been, and still is, a matter of practical difficulty, and much ingenuity has been displayed in devising electric lamps and electric candles, so as to produce a steady action. Arc lights may be made very powerful-one light some- times representing the power of thousands of candles. They are therefore specially suitable for large spaces, where great delicacy of illumination is not required. A light equal to a thousand or more candles can be obtained by the expenditure, on the dynamo, of one horse power. The other form of electric light is called the Incan- descent or Glow-lamp. To form this there is no break in the circuit, but there is inserted in it a length of some material so thin as to have a much diminished power of conducting the current, the consequence being that this length becomes so highly R 2 244 [CHAP. VII. ACTIVE BUSINESS. heated as to produce light. A small wire or ribbon of platinum or other metal will produce this effect, as will also a very thin filament of carbon, which is the substance commonly used. But if such a filament were highly heated in the open air it would at once be burnt up and destroyed; and to prevent this it is inclosed in a small glass globe exhausted of air by a mercury pump.* Electric glow-lamps are usually made to give a light equal to that of an ordinary gas-burner, say from 10 to 50 candle-power, but sometimes go higher. The light is soft and agreeable, and much better suited for domestic pur- poses than the glare of the arc light. But it is much more expensive, seeing that one horse-power applied to the dynamo will only produce a light of about 160 candles instead of 1000 as with the arc. Dr. Siemens has explained that glow lights could never rival the arc in economy of result, because the intensity of the latter could be made to approach that of solar light, whereas glow lights are limited in intensity to the fusing or dispersing point of the conductor employed. Moreover, the lamps are somewhat expensive to maintain, as the carbon filaments wear out and fail, and the globes often leak, or burst, by the pressure of the atmosphere. From what has been said it will be seen that the electric light is no novelty: the interest attaching to it at the pre- sent time is entirely due to the comparatively cheap rate at which the electric current can be produced in the dy- namo, by the expenditure of cheap mechanical power, instead of, as formerly, by the more expensive consump- tion of zinc in the galvanic battery. * As early as 1845 a Mr. King took out a patent for rendering incandescent, by the electric current, a carbon rod placed in a mercurial vacuum. It was intended for submarine illuminations, and for the safe lighting of coal mines. CHAP. VII.] 245 LIGHTHOUSES. The practical use of the dynamo was taken up by the brothers Siemens in London as soon as it had acquired importance. The machine which Mr. Siemens exhibited at the Royal Society in February, 1867, was made at the Chariton works, and the firm made afterwards some at- tempts to apply the invention to marine lights, as described in the patent; but these had no permanent result. Similar machines were afterwards tried, during some years, for other purposes, the most successful being the one indicated in Werner's earliest letters, namely, that of pro- ducing the explosion of mines by electrical ignition. But the action of the machine was found imperfect from the heating of the iron in the armature, and it was not till after the production of the "New Siemens" machine that the dynamo may be said to have established its full merits. After the patenting of this machine in 1873, the Charlton firm devoted themselves earnestly to its practical use, and its first great success was obtained by its application to the problem of the illumination of lighthouses. The lights hitherto established at Dungeness and else- where had all been produced by the magneto-electric machines. The Trinity House had not yet used the dynamo form, but when its superiority became known they turned their attention to it. They desired to place a very powerful light on the Lizard Point, and before deciding how this light should be pro- duced, they determined to make a careful inquiry as to the comparative merits of the various machines available. At the loan collection of scientific apparatus held at South Kensington in 1876, several dynamo machines might be seen at work for producing light, among which were the "Alliance" modification of Holmes's machine, the machine of Gramme, and the Hefner-Alteneck or New Siemens 246 [CHAP. VII. ACTIVE BUSINESS. machine. Although these were all successful in their effects, the latter machine was remarkable for its extraordinary compactness, and on that account attracted peculiar notice. Stimulated by this exhibition the Trinity House directed an exhaustive series of experiments to be made, which were carried out in 1876-7 at the South Foreland Lighthouse under the direction of their scientific adviser, Professor Tyndall, and their engineer-in-chief, Mr. (now Sir) James Douglass. The several machines were tried in comparison with each other, and when they were at work, the coal consumed, the light produced, and the horse-power absorbed were accu- rately measured by a series of experiments on shore; and the penetrating power and comparative intensity of the lights in various states of the atmosphere, and at various distances, were determined by a second series of observa- tions made on one of the Trinity yachts out at sea. The results of these experiments are given in a very complete Report issued by the Trinity House in the autumn of 1877. * Dr. Tyndall said :— As the result of these observations, the new machines, i.c. Siemens's and Gramme's, mark a great advance both as to economy and power in the application of the electric light to lighthouse purposes. Both inventions undoubtedly place at the disposal of the Elder Brethren of the Trinity House electric lights of a surpassing energy. Combining certain arrangements, a light transcending in power and individuality all other lights now existing would probably be obtained. The engineer, in a paper on the subject, said :— With reference to the electric luminary, it is doubtful whether * Accounts of the matter will also be found in Engineering of Oct. 19, and in the Times of Oct. 3, 1877. CHAP. VII.] 247 ELECTRIC LIGHTING. 1 any practical limit can be assigned to the intensity attainable with it, the question being limited by cost only. As a result of the inquiry, Messrs. Siemens were com- missioned to construct, on their principle, the electric appa- ratus for the Lizard, and the light was shown there for the first time in March, 1878. In November, 1878, Dr. Siemens was asked by the Council of the Royal Albert Hall to give his assistance upon a committee of scientific men to consider the possi- bility of applying electricity to the lighting of the hall and buildings. He gladly undertook the duty and supplied apparatus, with which, in the course of a few months, experimental lights were installed. On the 17th March the King of the Belgians visited the hall to see the effect. At the beginning of 1880, Dr. Siemens repurchased the apparatus and undertook further experiments at his own expense. 1 He paid, personally, great attention to electric light- ing. During this period he took out, independently of his inventions for the dynamo machines, five patents for improvements in lamps for the arc lights, and this branch of the business formed the object of his special care. When the dynamo and its application to electric lighting had become well-established, the managers of the Royal Institution of Great Britain, ever desirous to lay before its members the most accurate information as to the progress of practical science, asked Dr. Siemens to give them a lecture on the subject. He was pleased and flattered by the compliment; but he felt that in speaking of electric lighting he would be placed in a delicate position, on account of his 248 [CHAP. VII. ACTIVE BUSINESS. large business relations with work of the kind. He must either omit much that he might say, or he might appear to be making use of the opportunity to draw attention to his own personal affairs. He, therefore, declined the offer, and the lecture, a most excellent one, was given on February 17, 1879, by Professor Tyndall. Dr. Siemens agreed to supplement this with a lecture on the dynamo-electric current more generally, which was given on 12 March, 1880.* Electric Transmission of Power. When such a machine as the dynamo was once brought into existence it was sure to be taken advantage of for other applications of powerful electric energy. Several examples of these will be given in the next chapter; but it is necessary here to allude to one remarkable case which was among the earliest to which Dr. Siemens gave his attention. In this, the electric current is used, not for any action of its own, but merely as a vehicle for the transmis- sion of power; just as a boat on a river, or a waggon on a railway is used to transport some valuable commodity for use at a distant place. The power of horses, or of a water-fall, or of a steam-engine, is applied in a dynamo to excite a current that current is passed along a wire, and will, by the aid of another dynamo at the other end of the wire, reproduce the power (or a large portion of it) in a far distant locality. This use of electricity formed a favourite study for Dr. Siemens; and it seems to have first strongly impressed * These two lectures, taken together, give a full and interesting account of the rise and progress of this new phase of electrical industry, and for much of the foregoing information the author is indebted to them. CHAP. VII.] 249 ELECTRIC POWER. itself on his mind when, in the Autumn of 1876, he went to America and visited the Falls of Niagara. In all his many journeys in different countries nothing made such a deep impression on him as this wonderful natural phenomenon. The stupendous rush of waters filled him with fear and admiration, as it does every one who comes within the sound of its mighty roar. But he saw in it something far beyond what was obvious to the multitude: for his scientific mind could not help viewing it as an inex- pressibly grand manifestation of mechanical energy. And he at once began to speculate whether it was absolutely necessary that the whole of this glorious magnitude of power should be wasted in dashing itself into the chasm below?-whether it was not possible that at least some portion of it might be practically utilized for the benefit of mankind? He had not to think long before a possible means of doing this presented itself to him. The dynamo-machine had just then been brought to perfection, partly by his own labours; and he asked himself, Why should not this colossal power actuate a colossal series of dynamos, whose conducting wires might transmit its activity to places miles away? This great idea, formed amid the thunderings of the cataract, accompanied him all the way home, and was meditated on in the quiet of his study. He submitted it to the test of mathematical calculation, and so far con- vinced himself of its reasonable nature that he determined, when a fitting occasion arrived, to make it known. The opportunity arrived in the Spring of 1877, when he had to give an opening address as President of the Iron and Steel Institute. In that address he had to point out the dependence of the iron and steel manufacture on coal as a fuel. He alluded to the gradual diminution of the 250 [CHAP. VII. ACTIVE BUSINESS. stores in the earth of this valuable commodity, owing to the vast consumption of it for steam power; and he urged that other natural sources of force, such as water and wind, ought to be made more use of. And speaking of water- power, he made the following remarks:- The advantage of utilising water-power applies, however, chiefly to Continental countries, with large elevated plateaus, such as Sweden and the United States of America, and it is interesting to contemplate the magnitude of power which is now for the most part lost, but which may be, sooner or later, called into requisition. Take the Falls of Niagara as a familiar example. The amount of water passing over this fall has been estimated at 100 millions of tons per hour, and its perpendicular descent may be taken at 150 feet, without counting the rapids, which represent a further fall of 150 feet, making a total of 300 feet between lake and lake. But the force represented by the principal fall alone amounts to 16,800,000 horse power, an amount which, if it had to be produced by steam, would necessitate an expenditure of not less than 266,000,000 tons of coals per annum, taking the consump- tion of coal at 4 lbs. per horse power per hour. In other words, all the coal raised throughout the world would barely suffice to produce the amount of power that continually runs to waste at this one great fall. It would not be difficult, indeed, to realize a large proportion of the power so wasted, by means of turbines and water-wheels erected on the shores of the deep river below the falls, sup- plying them from races cut along the edges. But it would be impossible to utilize the power on the spot, the district being devoid of mineral wealth, or other natural inducements for the establishment of factories. In order to render available the force of falling water at this, and hundreds of other places simi- larly situated, we must devise a practicable means of transporting the power. Sir William Armstrong has taught us how to carry and utilize water at a distance, if conveyed through high-pressure mains, and compressed air* has been employed for the same This mode of transmitting power was proposed by Denys Papin CHAP. VII.] 251 THE FALLS OF NIAGARA. purposes. At Schaffhausen, in Switzerland, as well as at some other places on the Continent, power is conveyed by means of quick-working steel ropes passing over large pullies; by these means it may be carried to a distance of one or two miles without difficulty. Time will probably reveal to us effectual means of carrying power to great distances, but I cannot refrain from alluding to one which is, in my opinion, worthy of consideration, namely, the electrical conductor. Suppose water-power be employed to give motion to a dynamo-electrical machine, a very powerful electrical current will be the result, which may be carried to a great distance, through a large metallic conductor, and then be made to impart motion to electro-magnetic engines, to ignite the carbon points of electric lamps, or to effect the separation of metals from their combinations. A copper rod three inches in diameter would be capable of transmitting 1000 horse-power a distance of say thirty miles, an amount sufficient to supply one quarter of a million candle-power, which would suffice to illuminate a moderately sized town. This statement startled the audience considerably; and it is still remembered that, when it was delivered, a smile of incredulity was observed to play over the features of many of his hearers. But he was not to be laughed out of his idea; and as a reproof to the dulness of the unbelievers, he took the bold step of bringing the subject under the notice of the two public bodies who were certainly most competent to criticize it, namely, the Royal Society, and the Physical Society, giving them the full explanation, not only of the theoretical calculations on which he had based his asser- tions, but also of some practical details, by which he considered they might be carried into effect. It will be seen in the next chapter how Dr. Siemens's in 1688. The boring machines for piercing the great Alpine tunnels were worked in this way.. 252 [CHAP. VII. ACTIVE BUSINESS. idea of the electric transmission of power has been made practically available. MISCELLANEOUS INVENTIONS. We may here give an account of several scientific inven- tions on which Dr. Siemens occupied himself during this period of his life. Electric Pyrometer. In 1871 he gave to the Royal Society a communication, describing an invention which he thought of considerable importance, namely, an improved pyrometer, or thermometer for very high temperatures, acting by electricity. The exact measurement of great degrees of heat had always presented serious difficulties, the ordinary means being a very rough one, contrived by Wedgwood, and acting by the contraction of an argillaceous material. This subject had arisen in his mind about ten years before. When he was engaged, in 1860, on the Rangoon and Singapore telegraph cable, some observations led him to believe that variations of electrical resistance might be made use of to determine variations of temperature; and he addressed a letter to this effect to Dr. Tyndall, which was printed in the Philosophical Magazine of January, 1861. He said :- I was desirous to know the precise temperature of the coil of cable on board ship at different points throughout its mass, having been led by previous observations to apprehend spontaneous generation of heat. As it would have been impossible to intro- duce mercury thermometers into the interior of the mass, I thought of having recourse to an instrument based upon the well ascer- tained fact that the conductivity of a copper wire increases in a simple ratio inversely with its temperature. CHAP. VII.] 253 ELECTRIC PYROMETER. He then described the instrument, and added :— The ratio of increase of resistance of copper wire with increase of temperature may be regarded as perfectly constant within the ordinary limits of temperature; and being able to appreciate the tenth part of a unit in the variable resistance coil employed, we have the means of determining with great accuracy the temperature of the locality where the resistance coil is placed. Resistance thermometers of this description might, I think, be used with advantage in a variety of scientific observations ; for instance, to determine the temperature of the ground at various depths throughout the year, or of the sea at various depths; or by substituting an open coil of platinum wire for the insu- lated copper coil, this instrument would be found useful also as a pyrometer. This latter object seems clearly to have been most prominent in his mind, as he was then engaged in experi- ments on his Regenerative Furnace, and felt the want of such an instrument. He did not then perfect it; but at the meeting of the Iron and Steel Institute at Merthyr, in Sep- tember, 1870, he described the instrument itself as it might be applied to iron furnaces; and on the 27th April, 1871, he read the paper to the Royal Society, giving a more full and general scientific account of it. This paper was entitled, " On the increase of Electrical resistance in Conductors with rise of Temperature, and its application to the measure of Ordinary and Furnace Tem- peratures; also, on a simple method of measuring Electrical Resistance." It was honoured by being made the Bakerian Lecture for the year. The first part treated scientifically of the general prin- ciple; the second and third described the instruments for its application.

Nothing of importance appears to have been practically done with the instrument for some years; but at a later time it was applied successfully to several useful purposes, as will be stated in the next chapter. Bathometer and Attraction Meter. During this period also, Mr. Siemens perfected an instru- ment for determining the depth of the sea without the use of the sounding line. This, like the pyrometer, had engaged his attention many years before. In his earliest submarine cable opera- tions, he had seen what an immense advantage such an instrument would be, and he had conceived the idea on which it might be designed. It occurred to him that the total attractive force of the earth must be sensibly influenced by the interposition of a comparatively light substance, such as water, between the vessel and the solid portion of the earth below; and that the degree of diminu- tion would depend on the depth of the water. Hence, if an instrument could be produced sensitive enough to show the diminution of gravity, this would indicate at the surface the depth of the sounding. He constructed such an instrument, and it was tried, in 1859, on board H.M.S. Firebrand, then engaged in some soundings in the Bay of Biscay. It was sufficient to esta- blish the correctness of the principle, as its indications agreed generally within 10 per cent. with actual soundings; and on the strength of this, considering the novelty of the principle, Mr. Siemens communicated a description of the CHAP. VII.] 255 BATHOMETER. instrument to the British Association at their meeting at Manchester in 1861. The instrument, however, was im- perfect, and there were practical difficulties in its manage- ment which caused it to be laid aside. Some years later, certain operations in laying submarine cables, revived in him the conviction that an accurate instrument of the kind would be of considerable value, not only to the cable layer, but to the navigator generally. He again took up the subject and succeeded in making a better instrument on the same principle, which he described in a paper presented to the Royal Society in February, 1876, and published in the Philosophical Transactions. He called it a “ Bathometer," and gave an account of its trial on board the Faraday, in October, 1875, which showed results considered satisfactory. an " The same Paper contained also a description of another instrument, contrived by him on an analogous principle but for measuring horizontal attractions. This he called "Attraction Meter." It was so sensitive to external attraction that the moving of a person from one side of it to the other caused a sensible indication. It was also clearly influenced by the gravitation of the sun and moon, the fluid in it being, in fact, subject to a perceptible daily tide. Deep Sea Photometer. In the course of investigations as to the nature of life at great depths in the ocean, questions had been mooted depending on the penetration of light into deep water. The subject was mentioned to Dr. Siemens, and he at once contrived an instrument to determine this by actual experi- ment, and it was tried on board H.M.S. Shearwater in August, 1871. 256 [CHAP. VII. ACTIVE BUSINESS. It consisted of an apparatus by which, when sunk in the sea, sensitive photographic papers could be exposed for any length of time, at the will of the operator. The papers were contained in glass tubes enclosed in a box, and the exposure was effected by an electric apparatus attached to the cable by which the box was lowered. Several tubes could be thus exposed at different depths, and when drawn up, the whole could be "developed" by the usual photo- graphic process, and the influence of the light could be observed and recorded. Trials of the instrument were made in the Mediterranean, and the results were thus stated by Dr. Siemens :— Taking impressions at intervals of twenty-five fathoms, the results proved clearly that the effect of light diminished at a uniform, but rapid ratio, the paper being blackened at twenty- five fathoms depth, browned at fifty fathoms, stained yellow- brown at seventy-five, and only faintly tinged at 100 fathoms after five minutes' exposure. Darkness seems, indeed, to set in fast when you descend above 100 fathoms ; but light in even measurable quantities will unquestionably descend to a much greater depth, and there exercise its influence upon animal and vegetable life. What I wanted to establish was the ratio of decrease, but the experiments made did not suffice for this purpose; and I had not time to continue them. It is worthy of remark that there was only an action by the vertical ray of light; for although the tubes were exposed to the light all round, their axes being horizontal, only the uppermost surface of the sensitive paper was acted on, and this so strongly as to penetrate two layers of the paper at thirty fathoms; but there was an absolute absence, it appeared, of diffused light, the lower side of the papers being perfectly unaffected. The apparatus was shown in the exhibition of 1872. CHAP. VII.] 257 ARMOUR PLATING, Vessels to Resist High Pressure. In 1877 Colonel Beaumont, who was making large use of compressed air as a source of power, complained to Dr. Siemens that he had found great difficulty in getting receiving vessels sufficiently strong to withstand the very high pressure which he desired to use. This intimation was sufficient to put Dr. Siemens's inventive powers into action, and he forthwith designed a new kind of vessel, to be used as a reservoir or boiler, which, while it was remark- able for its lightness, was of strength capable of resisting great internal pressure. One of these vessels was made with a capacity of 100 cubic feet, not exceeding 2 tons in weight, and was per- fectly tight at 1300 lbs. pressure per square inch. He described it to the Institution of Mechanical Engineers in 1878. Armour Plating for War Vessels. In 1877 Dr. Siemens gave some attention to a subject which had been before scientific and mechanical men for some years, namely, that of the protection of ships of war by iron armour against the fire of heavy artillery. The necessity of this became apparent after the Crimean war, and the Warrior, the first ship so armed, was launched in December, 1860. In the following year the Government appointed a committee, afterwards well known as the "Iron Armour" or "Iron Plate" Committee,* to investigate the principles which should guide the design and use of iron armour; and they, during four years, made a great number of experiments and trials, and presented to the Govern- ment a number of valuable reports on the subject. The experiments were chiefly made on a large practical scale * Of which the author of this work was a member. S 258 [CHAP. VII. ACTIVE BUSINESS. by firing shot and shell from heavy guns against targets of full size, constructed to represent portions of a ship's side, and noting the resistance offered and the extent of damage done. These experiments were subsequently continued by other Government bodies, and were often discussed among scientific men. It was natural that Dr. Siemens, having so much experience in the properties of iron and steel, should give his mind to the subject. In January, 1878, he addressed a long letter to the Secretary of the Admiralty proposing a plan of his own, for which he had obtained a provisional patent. This plan was never brought to trial, but it is charac- teristic of Dr. Siemens that, in describing his scheme, he did not waste time in guesses or speculations, but went at once to matters of principle. He began by scienti- fically calculating the amount of energy "residing in the projectile," as he termed it; after which he explained what sort of effects this was capable of producing, and how proper provision must be made for receiving this amount of energy, and disposing of it in such a way as would cause the least damage to the ship or her crew.* * In this mode of stating the subject, Dr. Siemens hit exactly on what was perhaps the greatest difficulty the Iron Armour Committee had to encounter in getting the nature of the problem properly understood. People thought generally that the way to keep shot from entering a vessel should be the same as would be applied to keep a burglar from breaking into a strong box; namely, by protect- ing it by a covering extremely hard, and therefore supposed to be impenetrable. Hence the hardness of the iron, or supposed im- penetrableness of the steel, was assumed to be the great object to be attained. The committee strove earnestly to explain that this was a great error. The action of a burglar and of a shot were shown to be incapable of comparison with each other, one being a static, the other a dynamic action. When the shot arrived, there was " residing in it,” according to Dr. Siemens's expressive phrase, a very large amount of CHAP. VII.] 259 SCIENTIFIC SOCIETIES. SCIENTIFIC SOCIETIES, LECTURES, ADDRESSES. It has been stated that at this period of his life Dr. Siemens devoted much time to scientific and literary occupations not immediately connected with his practical business. He belonged to all the general and technical institutions. connected with mechanical or physical science; he was proud of his membership with them; he willingly took office in them; he never grudged the attention required for their affairs; he was a very frequent attendant at their meet- ings; he wrote papers for them; joined in their discus- sions; and aided them by every means in his power. But further than this, he was always ready, when called on, to aid institutions of a more general character, to which he did not belong, particularly those that were connected in any way with education. He would deliver lectures or mechanical power or energy, which must be expended in some way or other. It was, therefore, folly to attempt to resist it-to shut it out. The proper way was to accept it, to receive it, and to make provision for its being expended in the least harmful way. To humour the public notion, numbers of trials of hard steel plates were made, but always with the result that theory predicted; the energy being unable to expend itself otherwise, broke up the plates (since hard plates were always more or less brittle), and scattered the fragments far and wide, so doing about the maximum of mischief possible. The committee took quite the other tack: they offered something for the shot to do; they provided plates, not of hard steel, but of soft iron, which would admit of being battered about without fracture, and so would occupy and expend the energy of the shot while still protecting the vessel. This preference for soft iron over hard steel was incomprehensible to the public; it was never thought very well of by the authorities; and even now it is doubtful whether the principle on which it was founded, and which was so aptly seized at the first moment by Dr. Siemens, is really understood and acted on. The Iron Armour Committee, while in the midst of most useful work, were prematurely dissolved on political grounds, and new Admiralty and Ordnance kings arose who knew not their thoughts and ways.

His connexion with some of the societies, and his com- munications to them, have been noticed in previous chapters; but it is necessary here to make a more special mention of his transactions with them, and with other public bodies. The Royal Society. In this, the most important of the societies, he met the greatest number of scientific friends. He attended the meetings whenever he could, and he contributed several original papers at different times. Some of these were printed in the Philosophical Transactions, an honour accorded only to those papers which are esteemed of special scientific merit; and one of them had the further distinction of being selected for the "Bakerian" Lecture, thereby gaining a small prize, awarded annually to papers of remarkable character. He had further distinctions awarded him by the society, being elected at the annual meetings in November, 1869, 1870, 1878, and 1879, to serve on the Council for the four sessions following those dates. There are further connected with this society two clubs, called the Royal Society Club, and the Philosophical Club. These are very select institutions, each with a limited number of members; membership in both is restricted to Fellows of the Royal Society; and in the latter to those who have had papers published in the Philosophical Trans- actions; and election into them is very eagerly sought. Dr. Siemens was elected into the Philosophical Club in November, 1870, and into the Royal Society Club in June, 1871. CHAP. VII.] 261 SCIENTIFIC SOCIETIES. The British Association for the Advancement of Science. This body was also very congenial to Dr. Siemens from its dealing with so many branches of science, mathematics, physics, chemistry, and mechanics, in which he was specially interested. He was a regular attendant at their migratory meetings, in different parts of the country, and he always had some new and important communications to lay before them. He served on the Council of the Association from 1871 to 1875. At the meeting at Bradford, in September, 1873, he delivered, at the invitation of the council, a lecture to the operative classes on "Fuel." As it was a subject he had made peculiarly his own, it will be readily understood that he did it full justice, and the lecture is an example of profound scientific knowledge explained in a popular and easily intelligible manner. Institution of Civil Engineers. Dr. Siemens had now become so popular in this, the chief technical society in his own profession, that, in December, 1871, he was elected a member of Council, a position which he retained during the whole of his life, being re-elected every year. At the time of his death he stood next in rank for nomination as one of the vice- presidents, and he would have undoubtedly become president a few years later. He was indefatigable in the personal aid he gave to the business of the Council; and it is almost superfluous to say that he commanded the respect and esteem not only of his brother officers, but of all the members who had the good fortune to know him. 262 [CHAP. VII. ACTIVE BUSINESS. Institution of Mechanical Engineers. This institution, a body of civil engineers practising more especially the mechanical branch of the profession, was always sympathetically esteemed by Mr. Siemens, on account of his own kindred tastes and occupations. He was elected a member in 1851 (the fourth year of its exist- ence); and he afterwards served for twenty-eight years as a member of Council, and for four years as vice-president. In 1872 he was chosen President, holding the office for two years. The first meeting under his presidency was held at Liverpool, in July, 1872, when he gave an opening address, referring chiefly to the internal affairs of the body. Iron and Steel Institute. In the year 1869 a society was founded under the name of the Iron and Steel Institute, for the study and discussion of subjects connected with the manufacture and use of these metals. The first President was the Duke of Devonshire, K.G., and the first meeting was held in London on the 23rd June of that year. Mr. Siemens warmly approved the establishment of this Society. He was one of the original members, and in 1871 he was elected member of Council. One of the first things the Society did was, in September, 1870, to visit the Siemens Steel Works at Landore, then recently established; the members were conducted over the works by Mr. Siemens and Mr. Gordon, and the whole process of manufacture was shown and explained to them. Mr. Siemens had frequently afterwards to attend the reading of papers by other members, on his own inventions and processes, and he never failed to meet, in the best spirit, any criticisms made upon them. CHAP. VII.] IRON AND STEEL INSTITUTE. 263 In 1875 he was presented with the Bessemer Gold Medal of the Society, "in recognition of the valuable services he had rendered to the iron and steel trades by his important inventions and investigations." In 1877 he was elected President for the year; and on the 21st March he opened the sessional meetings held in London, with an address, which, as might naturally be expected, was interesting in an unusual degree. It referred to many topics, all pertinent to the interests of the members of the Society. Among these was the subject of fuel. After pointing out the advantages of the British Islands in this particular, he alluded to the remarkable industrial use of natural gas in America, and he took the opportunity of mentioning a novel idea of his own. He said :- The application has reminded me of a project I put forward a good many years ago,* namely, to erect gas producers at the bottom of coal mines, and by the conversion of solid into gaseous fuel, to save entirely the labour of raising and carrying the latter to its destination. The gaseous fuel, in ascending from the bottom of the mine to the bank would (owing to its temperature and low specific gravity) acquire in its ascent an onward pressure sufficient to propel it through pipes or culverts to a considerable distance, and in this way it would be possible to supply townships with heating gas, not only for use in factories, but to a great extent for domestic purposes also. According to the general definition of fuel given above, we * The following passage occurs in a letter to Mr. Joseph Phillips, September 3, 1866, referring to his gas furnace : "It is my ultimate intention to place the gas producers at the bottom of a coal mine, within reasonable distance of the works, the hoisting and carting of coal will thus be entirely saved, and the ascending gas column will produce sufficient propelling force to send the gas through several miles of culvert. At the Mersey works I have placed the gas producers in a tunnel below the iron works, proving the practicability of the plan." 264 [CHAP. VII. ACTIVE BUSINESS. have to include the evaporative effect of the sun's rays, by which sea-water is raised to elevated mountain-levels, whence it descends towards the sea, and in so doing is capable of imparting motion to machinery. This form of fuel has been resorted to in all countries since the dawn of civilization, and it is owing to this circumstance that the industries of the world were formerly very much scattered over the valleys and gorges of mountainous districts, where the mountain stream gave motion to the saw-mill or flour-mill, to the trombe of the iron smelter, and to the helve of the iron and steel manufacturer. It is not unreasonable to expect that the advantage of utilizing natural forces, which we could afford to neglect during a period of general prosperity, will become again an essential element in determining the very lowest price at which our produce may be sent into the market. In illustration of this Dr. Siemens gave the remarkable statement in regard to the value of the water-power in the Falls of Niagara, which has been quoted on page 250. In the autumn of 1878, still during Dr. Siemens's presi- dency, the Institute met in Paris. This meeting was prompted by the great Exhibitions held there, backed by special invitations from the Institution des Ingénieurs Civils, the Société d'Encouragement pour l'Industrie Na- tionale, and the Directors of the Conservatoire des Arts et Métiers. The invitation was gladly accepted, as afford- ing the English members an unusually good opportunity, not only of studying the splendid collections of iron and steel, from all nationalities, gathered in the Exhibition, but of visiting the celebrated French iron works within easy reach. It was fortunate for the Institute that this visit happened during the presidency of Dr. Siemens, inasmuch as his widely-extended European reputation, his acquaintance with the French and other continental languages, and CHAP. VII.] SOCIETY OF TELEGRAPH ENGINEERS. 265 his familiarity with foreign customs and habits, gave a character and éclat to the meeting, which could scarcely have been gained under the management of an English. President, however eminent in science or technology. The first meeting was held on the 16th of September, in the large hall of the Société d'Encouragement, the members being formally welcomed by the heads of the French societies who had given the invitations. At the conclusion of the formal reception ceremonial, Dr. Siemens gave an address, in which he pointed out the international character of the Institute, and enlarged on the advantages of the French systems of scientific and technical education. The address was translated and widely distributed in France. After the business of the Institute in Paris was concluded excursions were made to three of the principal establish- ments in the French iron trade, namely, to the works of Messrs. Schneider, at Creusot;-to the "Terre Noire" works at St. Etienne ;—and to the iron works and collieries of MM. de Wendel, at Hayange, and Sterling Wendel, in Lorraine. Society of Telegraph Engineers and Electricians. This society was founded in the year 1872, and an appro- priate compliment was paid to Dr. Siemens by electing him the first President. He gave, on the 28th of February, his opening address, the most salient points of which were a justification of the establishment of the society, and an at- tempt to define the position and duties of such institutions generally. In 1876 he presented, to the society a handsome marble bust, sculptured by Mr. Edward Davis, of Sir Francis Ronald, who, as early as 1816, had demonstrated by actual experiment the possibility of an electric telegraph. 1 266 [CHAP. VII. ACTIVE BUSINESS. In 1878 he was again elected President, and on the 23rd of January gave a second address, in which he congratulated the society on its increase and prosperity, and gave an analysis of the state of knowledge and practice in the applications of electricity. Institution of Naval Architects. This society was founded in March, 1860, “to promote the improvement of ships and of all that specially apper- tains to them." Dr. Siemens was one of the first members. In 1876 a paper on the Faraday telegraph cable ship was read by Mr. Merrifield, and Dr. Siemens took part in the discussion. He frequently spoke at the meetings, generally on the quality and uses of steel for shipbuilding, a subject which often came before the society. The Hall of Applied Sciences. Towards the end of this period he made a munificent proposition, referring to the various institutions established for the study of engineering subjects. In addition to the chief and most general of these, the Institution of Civil Engineers, he had noticed the growth of minor societies. representing various special branches of civil engineering. Indeed, in his position as the first President of one of these, he had encouraged their formation, and clearly justified their raison d'être. It occurred to him that it would be a good thing to com- bine them together, and he gave expression to this idea in his presidential address to the Iron and Steel Institute in March, 1877, suggesting that a large building should be erected, in a good locality, for their joint accommodation. In 1879, when he retired from the presidency of that CHAP. VII.] 267 SOCIETY OF ARTS. body, he offered a sum of £10,000 towards the erection of such a building, subject to the condition, "that it should be erected in Westminster, and that its ultimate management should be in the hands of a joint committee on which the different societies should be represented, under the presidency of the President of the Institution of Civil Engineers, the parent institution of engineering science." He brought the project before the councils of the various societies interested; and they expressed their warm appre- ciation of his liberality. The matter was discussed for some time, but difficulties arose in regard to the mode of carrying out the scheme, and it fell to the ground. At the same time the general idea presented such ob- vious advantages, that a strong opinion appeared to be entertained that it would sooner or later be carried into effect. It is only to be regretted that the opportunity should have been lost, not only of getting such a large contribution to the funds, but of obtaining the aid of a man who, by his distinguished position and energetic character, would have been certain to carry it nobly through. The Society of Arts. This was the first society he joined, having become a member in 1849; and at the time of his death he occupied the highest position in it (except the permanent President, the Prince of Wales), namely, the Chairman of the Council. As early as 1844 specimens of his Anastatic Printing had been exhibited there, and in the year of his election he gave a description of his brother's telegraphic inventions, the excellence of which attracted considerable notice. The following year he presented a paper descriptive of his new Regenerative Condenser, for which (as has been 268 [CHAP. VII. ACTIVE BUSINESS. already stated in Chap. V.) he received the award of the society's gold medal. He always held this award in high esteem, and on the very last occasion when he took the chair at the society, 27 June, 1883, in acknowledging a vote of thanks passed to him, he said, “The Society of Arts had a very old claim on him. It was the first society with which he became connected, and the first which recognized his labours by awarding him, in 1850, its gold medal." In 1874 and 1875 he was elected to serve on the council, and in the latter year the society thought it right to offer him a more substantial proof of their appreciation of his efforts to promote their objects by awarding him their Albert medal. This was founded in 1863, in memory of H.R.H. the Prince Consort, "to be awarded by the council not oftener than once a year for distinguished merit in promoting arts, manufactures or commerce." It is a gold medal of large size, with a handsome artistic design, exe- cuted by Mr. Leonard Wyon. The medal is the greatest honour the society can bestow; the award is adjudged with great formality and deliberation, and its recipients have been men of high distinction. The first award, in 1864, was to Sir Rowland Hill; the second to the Emperor Napoleon III.; and the third to Michael Faraday. In Dr. Siemens's case the award was made, according to the resolution of the council,- For his researches in connection with the laws of heat, and the practical application of them to furnaces used in the Arts; and for his improvements in the manufacture of iron; and generally for the services rendered by him in connexion with economisation of fuel in its various applications to the manufactures and the Arts. The medal was presented to Dr. Siemens by H.R.H. the Prince of Wales, as President of the society, at Marl- borough House, on the 22nd of February, 1875.

He was elected a Fellow of this in November, 1870, and he chose it to receive the more scientific explanations of his metallurgical processes. Royal Institution of Great Britain. He became a subscriber to this institution at an early period, and at a later time he was elected a vice-president and one of the managers. He took much interest in the proceedings, and delivered several Friday evening lectures. One of these, which attracted much curiosity, was given in February, 1876, on the peculiar quality of sensitiveness to light inherent in selenium; and with his remarkable facility at reducing scientific discoveries to practical shape, he devised what he called a selenium eye, i.e., an apparatus. made in the shape of an enlarged human eye, which was sensible to light and to difference of colour; which showed fatigue under intense light; and which recovered therefrom by repose in keeping the eyelids closed. He stated further that it would not be difficult to make the closing of the eye to a bright flash automatic, thus imitating the spontaneous or reflex action of the human organ. United Service Institution. On the 3rd of March, 1879, Dr. Siemens gave an im- portant lecture at this Institution, "On the Production of Steel and its Application to Military Purposes." The chair was taken by Gen. Sir Henry Lefroy, K.C.M.G., who, in introducing the lecturer, said :— It is scarcely necessary for me to remind you that you have before you one of the most distinguished physical philosophers of the present day. We have to do, to-night, not with the dis- 270 [CHAP. VII. ACTIVE BUSINESS. tinguished electrician, with the constructor of the "Faraday," with the fertile inventor whose range has gone over subjects as various as the setting of type and the measure of the depth of the ocean; but with one of the most scientific metallurgists of England, the inventor of many remarkable processes in that art, and of whom it may be very safely said that he has touched no subject which he has not adorned. The meeting was attended by many experts in gunnery construction, and a discussion followed, in which the chair- man, Sir William Thomson, Mr. Barnaby (chief constructor of the navy), and General Younghusband (director of the Woolwich gun factory) took part; and Mr. Siemens replied. The proceedings at the meeting raised a controversy in the newspapers. Some of the speakers had offered a quasi apology for the limited use made of steel in large guns; partly on the ground of the expense, and partly because the peculiar properties recommending it had not been. sufficiently known. These statements were challenged in a letter to the Times by Mr. Bessemer, and a somewhat lengthy correspondence followed, in which the Woolwich authorities, Mr. Krupp and Dr. Siemens, expressed their opinions on the points in dispute. Athenæum Club. In 1871 Dr. Siemens received a great compliment from the Athenæum Club. This society was founded "for the association of individuals known for their scientific or literary attainments, artists of eminence in any class of the fine arts, and noblemen and gentlemen distinguished as liberal patrons of science, literature, or the arts." The number of members is limited, and the applications for admission being very numerous, it is necessary for a candidate to wait some 15 years after proposal before he CHAP. VII.] 271 ATHENÆUM CLUB. can be ballotted for. But as this necessity might keep suitable persons for a long time out of the club, a rule was enacted as follows: It being essential to the maintenance of the Athenæum, in conformity with the principles upon which it was originally founded, that the annual introduction of a certain number of persons of distinguished eminence in Science, Literature, or the Arts, or for Public Services, should be secured, a limited number of persons of such qualifications shall be elected by the Committee. The number so elected shall not exceed nine in each year. No election shall take place unless nine at the least of the Committee be actually present, and the whole of those present, unanimous in their election. . . The Club intrust this privilege to the Committee, in the entire confidence that they will only elect persons who shall have attained to distinguished eminence. Dr. Siemens had been proposed on the ordinary list in May, 1865, by Professor Graham, and seconded by Captain (now Sir) Douglas Galton. He might therefore have come on for ballot about 1880. But nine years before this time a motion was made in committee by Dr. E. Frankland for his election under the special rule, the following being the qualifications set forth on his behalf :- Author of numerous Papers in the Philosophical Transactions and other scientific journals on Dynamics, Heat, and Electricity; well known as an engineer and constructor of lines of submarine and land telegraphs; inventor of several valuable and important processes and apparatus in connection with the application of heat in gas-making, glass manufacture, and metallurgy; also of several kinds of new machinery and electrical apparatus. The application was duly considered, and Dr. Siemens was elected on the 21st February, 1871. The club are in the habit of electing annually a certain number of their most eminent and popular members to serve on their managing committee. Dr. Siemens was 272 [CHAP. VII. ACTIVE BUSINESS. also paid this further compliment in May, 1874, and he served till May, 1877. Glasgow Science Lectures. In 1878 an association formed in Glasgow for giving lectures on science in that town, requested Dr. Siemens to aid them, which he very willingly agreed to do. He delivered accordingly, in the City Hall, on the 14th March in that year, an address "On the Utilization of Heat and other Natural Forces." Beginning with general explanatory remarks about heat and fuel, he gave, with the aid of diagrams and models, descriptions of his regene- rative gas furnace, and of the utilization of power by electric transmission, adding a curious hint as to the pos- sible future use of the electric current for domestic matters. Having shown its capability of producing heat as well as light, he said :- I now propose to bring before you another simple experiment to show how readily the heat so generated may be employed for heating water. I will immerse the spiral coil of platinum wire in a glass jar containing about two pints of water, and after closing the electric circuit you will perceive, in the course of a minute or two that the water is brought to the boiling point; nor would this mode of heating water in small quantities be expensive if currents were laid on to our houses from dynamo-electric machines. And who knows whether, in the electrical age, towards which we seem to be gravitating, the apparatus before you may not be the common coffee-machine of the day? DOMESTIC LIFE. The beginning of 1870 was, in all respects, an anxious, harassing period. Siemens was On the 29th December, 1869, Mrs. Siemens taken ill with what proved to be an attack of scarlet CHAP. VII.] OXFORD DOCTOR'S DEGREE. 273 fever, so severe, that for some time her life was thought in danger. The distress caused by this to her husband was a sore aggravation of the effect of the bad news brought day by day from the Indo-European telegraph; but fortunately her good constitution carried her through, although it was the end of February before she was allowed to leave her bed-room. On the 11th of March, a change being necessary, she was taken by her husband to Torquay, where they spent a happy month, their pre- sence in the place attracting the visits of many relatives and friends. In the middle of this year Mr. Siemens received a high honour from the University of Oxford. The intimation of this was conveyed in the following letter from Lord Salisbury, the Chancellor of the University :- DEAR SIR, HATFIELD HOUSE, HATFIELD, HERTS, June 7, 1870. It is my pleasing duty to inform you that the University of Oxford desire to record their sense of your eminence in electrical and other sciences by conferring upon you an honorary degree at the approaching Commemoration. I trust that it will not be unacceptable to you to receive this token of their esteem; and that your engagements will permit you to come to Oxford for the purpose. The degree will be conferred on the morning of Tuesday the 21st inst. Believe me, yours faithfully, C. W. SIEMENS, Esq. SALISBURY. On the 20th June Mr. Siemens left for Oxford, accepting with his wife the hospitality of the Dean of Christ Church and Mrs. Liddell; and on the next day he received in the T 274 [CHAP. VII. ACTIVE BUSINESS. Sheldonian Theatre the honorary degree of D.C.L., which he always highly valued. A similar honour was also conferred, at the same time, on other distinguished men, among whom were Sir Edwin Landseer, Sir Francis Grant, Sir William Armstrong, Mr. Robert Lowe, and Mr. Matthew Arnold. In 1870 he again found reason to change his private residence. His social engagements were considerably increasing, and he and his wife felt the want of more spacious premises. Another motive also came into opera- tion. When Carl came to London he brought his family and household with him. This induced the brothers to look out for two houses together, which were found in "Palace Houses," opposite Kensington Gardens, in the Uxbridge Road. The two dwellings were put in communication by a conservatory; and from the be- ginning of 1870 to 1881 the two families lived as one. Dr. Siemens much enjoyed the companionship; and his domestic happiness went far to mitigate the troubles and anxieties attending his large and responsible business undertakings. There was much excitement in the two houses when, on the 15th July, 1870, war was declared between France and Germany. Dr. and Mrs. Siemens had previously decided to visit the Engadine; and although such a journey was thought by many to be a hazardous thing, neither the husband nor the wife felt any hesitation in undertaking it. They started on the 16th, and travelled via Antwerp and Düsseldorf to Cassel and Coburg, where they visited Rosenau (Prince Albert's birthplace), and gazed on the well-known Feste Burg, which inspired Martin Luther with his immortal hymn. CHAP. VII.] 275 FOREIGN TRAVEL. On arriving at Innsbruck, a carriage was hired to take them by Imst, Landeck, and Finstermünz, up the beautiful valley of the Inn. At Tarasp they met a Frenchman, who informed them, out of a French journal, that " Napoléon a passé le Rhin à Rastadt!" giving for the moment a terrible shock to their German sympathies! St. Moritz was reached soon after, where they remained three weeks. Returning to their new home, with larger surroundings and increasing social claims, Dr. and Mrs. Siemens received much more frequently, and their gatherings are still re- membered by many who had the privilege of invitations. They took a pleasure in collecting around them true artistic talent, which always drew from them respectful attention ; and they occasionally lent their large rooms to special professional friends for concerts, which were always well attended. In 1871, after attending the British Association at Edin- burgh, they spent some time at a pretty highland villa, which Dr. Siemens had taken for some years, "Craigdhu," near Kingussie. In November, 1871, Dr. Siemens, accompanied by his wife, started for Rome, in which city was held the third of a series of meetings of the "Universal Telegraphic Con- ference." This consisted of a body of delegates from all the countries of Europe, who met about every three or four years to discuss the progress of telegraphy, and in par- ticular such matters as had a bearing on international telegraphic communication. There was a large party in the Hôtel Costanzi, Dr. and Mrs. Werner Siemens and a niece joining them there. On the evening of their arrival, the 27th November, Rome was magnificently illuminated, in honour of King Victor Emmanuel's having opened the Italian Parliament that day in the Eternal City. T 2 276 [CHAP. VII. C ·ACTIVE BUSINESS. Their sojourn there, seven weeks, was full of interest, although many hours daily had to be given up to the important affairs of the Conference. They were surrounded by many friends of all nations; and on the 13th January, 1872, Werner and William inaugurated a handsome new dining-hall of the hotel by giving a banquet to nearly 100 people. On the following day they left Rome, and tra- velled homeward by Genoa and the Riviera. In July, 1873, Dr. and Mrs. Siemens went to Vienna for the Great International Exhibition there. A Royal Com- mission had been appointed to represent this country; and Dr. Siemens was chosen by H.R.H. the Prince of Wales to serve on one of the juries in the "Scientific Inventions" Division. Dr. He was engaged on this work from the 3rd to the 21st July, after which the party made a trip, with other friends, to the Dolomite country. The great iron works at Prévali and Hüttenberg, were visited, and at Villach Dr. and Mrs. Siemens made the ascent of the Dobratsch mountain; they slept there, and during the night were in the midst of a terrific thunderstorm. Siemens said he knew something about electricity, but had never been in such fearful companionship with it before; the atmosphere was in a blaze, and the thunder threw the earth into convulsions, as if opening to swallow them! But the next morning was calm and peaceful, and a magni- ficent sunrise repaid them for their discomfort. From this district Dr. Siemens was summoned back to Vienna to take part in a Congress on the subject of patents. The idea of it had originated with the Chief Commissioner of the Vienna Exhibition; and invitations had been issued to all nations, in the name of the Austrian Government, with a view to establishing international relations regarding CHAP. VII.] 277 SHERWOOD. the Patent Law. However, before the Congress assembled, the Austrian Government (like Frankenstein, as Dr. Siemens expressed it) became alarmed at their own creation, and the body, instead of being an official Congress, was simply a heterogeneous assemblage. Dr. Siemens was made pre- sident; and among his duties was that of explaining, if not translating, the speech of any member into any other of the four languages which were in use there. The occupation entailed much work and close attendance, and he and his party did not finally leave the city till August 11, when they returned by Salzburg, visiting the Königssee, Berchtesgaden, and the picturesque country around. The sad events of 1874 have already been described. In May of that year Dr. Siemens removed the London offices to more spacious premises, at No. 12, Queen Anne's Gate, overlooking St. James's Park, where they have since remained. The Sherwood House.-About the middle of this period, Dr. Siemens took a country house in addition to his London residence. He had several objects in this, irrespective of his con- stant love for fresh air. His business work, thanks to the presence of his brother Carl, and to the aid of many well- skilled assistants, had become easier, and a source of less anxiety than formerly; and he felt the inclination growing upon him to devote more attention to matters of science. For this object he wanted retirement for quiet study, and desired to get a place where," the world shut out," he could call his thoughts home and direct them uninterruptedly to the matters before him. Always keeping in mind beauty of scenery as his prin- cipal object, he fixed on one of the most lovely districts to 278 [CHAP. VII. ACTIVE BUSINESS. be found within a reasonable distance of the metropolis, namely, the neighbourhood of Tunbridge Wells. (6 After some searching he found a suitable estate called Sherwood," a mile or two to the east of the town on the road to Pembury. He purchased this at the end of 1874, and entered on its occupation early in the following year. Shortly afterwards, being greatly pleased with the place, he bought some land adjoining, extending the grounds to about 160 acres, laid out new ornamental plantations, considerably enlarged the house, and made many other improvements in the property. Among other alterations he fitted up on the pre- mises a comprehensive electric "installation," in which he showed how this wonderful agent could be reduced to human servitude in operations of domestic utility. In one of the outhouses he erected a steam-engine, which was made to work a dynamo-electric machine, so producing an electric current. This was utilized to light the house with glow lights, and the grounds with arc lights; and it also acted, by wires conducting it to various places, as the transmitter of power to perform work required on the estate, such as sawing, chaff-cutting, and so on. In the lower part of the grounds was a spring of water; and by carrying the conducting wires to that spot, the electricity was made to pump the water up to the house and out- offices. The waste steam from the engine was made use of for warming purposes. This installation gave him the power of trying many experiments with electricity, and particularly those on vegetation, noticed in the next chapter. The designing and execution of the alterations in the house and grounds were most successful. They not only -formed for him a delightful and beneficial relaxation, but they gave the whole place an attractiveness to him, which [Page 279. SHERWOOD-THE HOUSE. [Page 279. 00 SHERWOOD.-THE GROUNDS. CHAP. VII.] 279 FRENCH HONOURS, he retained all his life long. He never was so happy as when he was there. The two Plates inserted show the house and grounds from two of Sir William's favourite points of view. The estimation in which Dr. Siemens was held in France was shown by an honorary nomination as corresponding member of the celebrated "Société d'Encouragement pour l'Industrie Nationale”—an association founded in 1801 on the quieting of the nation after the great Revolution, and afterwards, in 1824, declared “d'utilité publique." The following was the complimentary letter sent him on this occasion :— PARIS, le 3 Septembre, 1875. J'ai l'honneur de vous annoncer que dans sa séance générale du 23 Juin, 1875, la Société d'Encouragement pour l'Industrie Nationale vous a nommé son Correspondant dans le Comité des Arts Economiques. La Société s'estime heureuse de trouver cette occasion de vous donner un témoignage de son estime, et de reconnaître ainsi les services que vous rendez à l'Industrie et au Commerce. Elle vous demande en échange, de l'aider dans sa mission, notamment en lui signalant les progrès industriels qui s'accomplissent autour de vous. Je me félicite également d'être son interprête dans cette circonstance et de pouvoir joindre à l'expression de ses senti- ments celle de ma considération la plus distinguée. Le President de la Société, Sécrétaire perpetuel de l'Académie des Sciences. J. B. DUMAS. This honour ranks only after membership of the Institute itself, which Dr. Siemens would in all probability soon have obtained had his life been longer spared. On the 28th of April, 1876, Mrs. Siemens's brother, 280 [CHAP. VII. ACTIVE BUSINESS. Lewis Gordon, died. From that time his mother and sister came to have their home with Dr. and Mrs. Siemens, he proving indeed a son and a brother. In May, 1876, the “Loan Exhibition" of scientific appa- ratus was held at South Kensington, and gave Dr. Siemens a good deal of extra work. On the 13th May he was com- manded to be at the exhibition to explain his model of the "Faraday” and other apparatus to the Queen and to the Empress of Germany. The following day he was honoured. by an invitation from the German Empress to the German Embassy, which was conveyed in the following letter:- KAISERLICH DEUTSCHE BOTSCHAFT, LONDON, den 10 Mai, 1876. Auf Allerhöchsten Befehl Ihrer Majestät der Kaiserin-Königin beehrt sich der Kaiserlich Deutsche Botschafter Herrn Dr. Wilhelm Siemens, ganz ergebenst zu benachrichten, dass Ihre Majestät Allergnädigst geruhen wird, ihn Sonntag den 14 Mai 1876, 3 Uhr nachmittags, auf der Kaiserlich deutschen Botschaft zu empfangen. JOHANNES BRANDIS. A number of "Conferences," on different subjects, were held during this exhibition; Dr. Siemens was president of one on mechanical subjects, and he gave a lecture, on the 27th July, on his bathometer and other measuring appliances. In the autumn of 1876 he visited the United States to attend the Exhibition at Philadelphia, for which he had been appointed by the Government one of the judges for scientific and philosophical instruments. He left Liver- pool, accompanied by his wife and her nephew, Mr. Joseph Gordon (who was subsequently appointed one of his executors), on the 22nd of September. CHAP. VII.] TELEGRAPHIC CONFERENCE. 281 • This American trip was very successful; much kind attention was shown, and a great dinner was given in Philadelphia in Dr. Siemens's honour. He visited Wash- ington, and afterwards went on to Niagara. On his re- turn home at the end of November, he found a large accu- mulation of work; but the complete change, and the two sea voyages, had been of much service to his health. On 20th June, 1877, Dr. and Mrs. Siemens gave a large "At home" in honour of his Majesty the Emperor of Brazil, who had expressed a wish to spend an evening with them. In June, 1878, he was made an honorary member of one of the oldest and most respected scientific societies, the Cambridge Philosophical Society. In 1879 the University of Glasgow, desiring to follow Oxford in acknowledging distinguished merit, resolved to award Dr. Siemens their honorary degree of LL.D. It was given on the 23rd April in that year, being the occasion of the installation of the Duke of Buccleuch as Chancellor of the University. In June, 1879, the "Universal Telegraphic Conference" met in London, and on the 14th they visited the works at Charlton. On the 9th of July, Dr. and Mrs. Siemens gave an entertainment at Sherwood in their honour. All the members of the congress, most of whom were naturally foreigners, were invited; and in addition there were asked to meet them a large number of guests distinguished either by rank or celebrity, including foreign ambassadors, representatives of scientific bodies, and persons of eminence in art or literature. The guests, numbering above 200, were conveyed from London to Tunbridge Wells and back by a special train, which was liberally placed at Dr. Siemens's disposal by 282 [CHAP. VII. ACTIVE BUSINESS. the South-Eastern Railway Company, without charge, as a compliment to the telegraphic body. There was a universal expression of gratification on the part of the guests, at the handsome and cordial reception they had met with, and the occasion was long remembered as one of the most successful fêtes champêtres that had ever been given. At the end of the year, Dr. and Mrs. Siemens again left for Italy. CHAPTER VIII. LAST YEARS. Age 57 to 60. 1880 to 1883.

THROUGH the remaining few years of Dr. Siemens's life we find him carrying out still farther the course of action he had followed in the preceding decade, namely, devoting less attention to common-place commercial interests, and more to subjects of an intellectual and speculative character. He had now no necessity to work for money, and he preferred to follow more recondite pursuits, partly for the mental pleasure they afforded him, and partly, no doubt, from a laudable ambition for personal fame. We may easily trace this by remarking a changed mode of treating his former subjects of occupation., 284 [CHAP. VIII. LAST YEARS. In regard to Heat, he left his gigantic furnace and metal- lurgical operations in a great measure to work themselves, while he contributed to the public advantage by showing how the smoke of towns might be prevented, the domestic hearth made more comfortable, and ordinary heating processes improved by new and superior applications of fuel. In Electricity, he was no longer seen in the workshops or the Faraday, directing the cable-spinning or the cable- laying; this he left to his partners and his well-trained staff. He now preferred to study how the electric agency might be more extensively applied to effect novel modes of illumination; or to melt substances hitherto infusible; or to take the place of the solar ray in the uprearing of the vegetable kingdom; or to bring the energy of the distant waterfall to grind corn in the city; or to Drag the slow barge, and drive the rapid car. Or, putting aside the practical use of this mysterious force, he would devise means to measure its power, or to define its properties. Even his mechanical inventions took a more advanced scientific character. He would contrive a thermometer for testing the heat inside the glowing furnace, or in other places inaccessible to ordinary measurement; he would sound the depths of the sea by simply looking at an instru- ment placed on the deck of a vessel; or discover how much sunlight illumined the mollusks who lived on the ocean floor. He devoted a large portion of this last term of his life to two scientific objects of the highest character. In the first place he undertook for a year the presidency and direction of one of the largest and most noted scientific bodies in the world; and, secondly, he startled the astronomers CHAP. VIII.] 285 THE GAS FIREPLACE. and physicists of Europe by an attempt, the result of long and careful study, to apply familiar physical principles to the solution of some of the most recondite problems con- nected with the solar system. On the other hand, he was not too proud to descend from these lofty heights whenever he could make his acquirements and talents useful. He would take the chair at a meeting of his brother engineers in Paris; would act as a judge at an electric exhibition in Vienna; would give evidence before half a dozen Royal Commissions; would lecture at literary institutions; preside at charity dinners ; and give away prizes to boys and girls in country schools. It delighted him to do what would benefit somebody, and he was by no means insensible to the rewards of gratitude and honour that his labours earned for him. HEAT SUBJECTS. In this latter period of his life Dr. Siemens kept up his interest in the subject of Heat. His inventions and works connected with the applica- tions of this form of energy had come to a splendid fruition, not only profitable to himself, but highly illustrative of scientific progress, and largely beneficial to industrial interests. But he did not by any means not by any means consider his task in this domain of science finished; he believed there were still many further applications to be made, for the benefit of mankind, of the great principles he had been concerned with, and he lost no opportunity of insisting on them. The Gas Fireplace. One of these inventions was of a kind that he intended to make interesting to every household; it was an improve- ment to the domestic fireplace. 286 [CHAP. VIII. LAST YEARS. One of the chief advantages of his Regenerative Gas Furnace was that it would, in producing its greatest heat- ing effects, make little or no smoke. He had noticed what indeed was only too patent to everybody, that one of the great evils of life in the metropolis was the pall of dirty fog which so often hung over its houses; and he knew, what many people did not, that the cause of its greatest annoyance was the mixture, with the natural aqueous vapour, of particles of soot emerging from the millions of chimneys in London buildings. Factory fires might be amended by his furnace constructions; but these, in London, were comparatively few, and the great mass of the evil arose from the domestic grates distributed among the population. Dr. Siemens, therefore, set his inventive powers to work, to see whether he could not do something to improve the domestic grate, and in particular to abolish, or at least diminish, the smoke produced therefrom. After experimenting for some time on his own premises, and satisfying himself that the ideas he had formed were sound and practical, he made his plan known by an article. published in the scientific periodical, Nature, of Nov. 18th, 1880. It was headed "A New Cure for Smoke," and it commenced as follows:- The growing obscurity which distinguishes the winter atmo- sphere of London has disposed men to consider whether it is an indispensable evil connected with the use of coal in great centres of population, or whether means can be found of providing the warmth and comfort which the copious use of mineral fuel affords us without having to pay the penalty of dispensing with the solar ray, of finding ourselves and everything we touch covered with soot, and of occasionally having, even at mid-day, to grope our way with a feeling akin to suffocation. I am decidedly of opinion that the evil is one which not only CHAP. VIII.] 287 THE GAS FIREPLACE. admits of remedy, but that its cure would result from a closer attention to the principles of economy in the use of fuel. After alluding to improvements made in large manu- facturing operations by his Regenerative Gas Furnace, he continued :— Since by the employment of gaseous fuel results such as these are realized, there seems no à priori reason why analogous results should not attend its application on a smaller scale, even down to the means of heating our apartments, which, although a small application in each individual instance, amounts, in the aggregate, to the largest of all the uses of mineral fuel. He then mentioned the fact that what were called “ 'gas fires" were frequently used, these being simply jets of coal gas, or coal gas mixed with air, allowed to play on pieces of asbestos or pumice stone, which after a time became heated, and so radiated off heat into the room. But he remarked that such fires were very expensive, gave insuffi- cient warmth, were cheerless in appearance, produced heat of an unpleasant character, and often gave out disagreeable smells. He then described his plan. While retaining the use of coal gas, as supplied by the gas companies, he proposed to use it in a different way. Instead of letting it heat masses of inert matter, he allowed it to play upon pieces of coke, which were thereby ignited and burnt, serving as fuel. The manner in which this was done was exceedingly simple; in fact it was nothing more than inserting a few gas jets in the front of an ordinary grate filled with coke, when the combination of the gas flames and the burning coke formed a fire very much superior in every respect to the ordinary gas arrangement, and in fact quite as satis- factory as the usual domestic fire from raw coal. This, although apparently so simple, was really a very 288 [CHAP. VIII. LAST YEARS. scientific invention; for its principle was that of re-supply- ing to the coke the hydrocarbons which had been abstracted from it, and so restoring the original elements of coal, but in an improved and refined form. Another scientific feature in the grate was that of supply- ing it, by a very simple and ingenious arrangement, with heated air, so as to increase the activity of combustion. It was, in fact, one element of his regenerative gas furnace brought into the drawing-room. He claimed the following advantages from this kind of fire as compared with the common one :— 1. Absence of smoke. 2. Greater heating power at less cost. 3. Facility of lighting, without the usual "laying" of paper and wood. 4. Keeping alive without attention or stirring. 5. Ease of regulation and adjustment, according to the heating effect required. 6. Capability of being lighted, or allowed to go out, at any moment, which is not only a great convenience, but means considerable economy. * The principles of the grate were applied to larger kitchen ranges. A gentleman in the City of London wrote, July, 1882:- The Siemens's apparatus recently fitted to a large Kitchener in my house at Chislehurst is working admirably. Having watched its operation very closely, I am convinced that in cleanliness and efficiency it is the best outcome of the recent Smoke Abatement Exhibition. * The author has used two of these fires for some years, one in a sitting-room and one in a bed-room, and they are found most effective and most convenient. They are sometimes used with coke and some- times with coal, but usually with a mixture of the two. The invention may be characterized as a great domestic blessing. It is made for sale by Messrs. Sugg & Co., Gas Engineers, Westminster. CHAP. VIII.] 289 SMOKE ABATEMENT. I find that with an almost inappreciable consumption of gas, the coke, which is the only fuel used, soon ignites, and by regular feeding at the top, a brilliant smokeless fire can be maintained. No nuisance of any kind is created, all the gaseous products of combustion being carried up the chimney. The absence of smoke in the flues and chimneys is the most remarkable feature of this ingenious invention, and if its originator receives no further rewards, he will ever command the choicest blessings of grateful scullerymaids. When first erected the innovation was assailed in the fiercest way by the cook, and all the latent caloric in her system seemed scarcely sufficient to give forcible expression to her injured feel- ings. But by a judicious combination of tact with firmness, in addition to my own personal supervision, she has become, in the short space of three months, a sincere and ardent admirer of the system. Of the saving of cost I am not yet able to speak, but I am making comparative experiments in this direction. On this latter point Dr. Siemens had some trials made under his own superintendence, with kitcheners fitted up by the Falkirk Iron Company. The temperature in the ovens was got up to 246° Fahr. in an hour, with the con- sumption of 8 cubic feet of gas; up to 500° in another hour with an additional 7 cubic feet; and up to 580° in another three-quarters of an hour with 4 cubic feet more. The coke consumed was 22 lbs. until the fire went out in the afternoon. The cost in another case was said to be 4 d. for coke and gas for the 12 hours in a medium-sized range. The Smoke Abatement Movement, About the same time that Dr. Siemens brought out his grate, a movement was set on foot for abating the nuisance of smoke in London, an object in which he heartily concurred. After some preliminary proceedings, a meeting was held U 290 [CHAP. VIII. LAST YEARS. at Grosvenor House on the 24th July, 1881. Dr. Siemens attended, and in a speech of considerable length moved the first resolution: "That the present smoky condition of the atmosphere of London injuriously affects the health and happiness of the community, besides destroying public buildings, deteriorating perishable fabrics, and entailing in various ways unnecessary expenditure.” He attended and spoke at several other meetings. His arguments were always the same, namely, urging the sub- stitution of gas as fuel, for raw coal. As a result of this movement it was decided to organize an exhibition of improved fire grates, cooking and warming apparatus, furnaces, and apparatus of all kinds, either for domestic or industrial use, devised to prevent smoke, or to consume smokeless fuel. This was held in the Exhibition Buildings at South Kensington; it was opened on November 30, 1881, and remained open till 14th February, 1882. Prizes were instituted for the most meritorious devices. Dr. Siemens himself offered 100 guineas "for the best method or arrangement for utilizing fuel as a heating agent for domestic and industrial purposes, combining the utmost economy and freedom from smoke and noxious vapours." Half this was awarded to the Dowson Economic Gas Company; and the other half to the Falkirk Iron Company for their gas and coke burning kitchener. His Royal Highness the Prince of Wales visited the exhibition on the 4th January, 1882. He examined in detail the various sections, and received explanations from the committee and from various exhibitors. He stayed fully to inspect the gas, coke, and anthracite fires on Dr. Siemens's principle, which were explained to him by Dr. Siemens him- self. His Royal Highness on leaving expressed the pleasure he had felt in viewing the exhibition, and his belief that CHAP. VIII.] 291 SMOKE ABATEMENT. the appliances brought before the public would be useful to the community; he considered, he said, that the executive committee and all concerned were doing a great work from a sanitary point of view. Another meeting was held at the Mansion House on the 16th of July, 1883, the chair being filled at first by the Lord Mayor, and subsequently by the Duke of West- minster. Sir William Siemens attended and made an effective speech. Sir William Thomson, in his obituary notice of Sir William Siemens, written a few days after his death, says :- On the 19th of this November the writer of the present article was accosted in a manner of which most persons occupied with science have not infrequent experience, "Can you scientific people not save us from those black and yellow City fogs?" The instant answer was, "Sir William Siemens is going to do it; and I hope, if we live a few years longer, we shall have seen almost the last of them." How little we thought that we were that very evening to lose the valuable life, from which we were promising ourselves such great benefits! May we not hope that, after all, the promise was not vain, and that, although Sir William Siemens is gone from among us, the great movement for smoke abatement, in which he has so earnestly laboured during the last three years of his life, may have full effect? After the Smoke Abatement Exhibition was over, Dr. Siemens received an intimation that the Prince of Wales would like one of the gas fires fitted up at Marlborough House. Dr. Siemens gladly undertook the commission, and caused a grate to be erected there under his own superintendence. It answered well, and His Royal Highness was pleased to express his thanks to Dr. Siemens by sending him his photographed portrait, which was accompanied by the following letter:- U 2 292 [CHAP. VIII. LAST YEARS. MARLBOROUGH HOUSE, PALL MALL, S.W., 9 Februar, 1882. VEREHRTESTER HERR DOCTOR,- Erst gestern Abend hatte ich Gelegenheit vom Prinzen von Wales zu hören, und mich durch eigenen Augenschein zu überzeigen, wie vorzüglich die Aenderungen an den neuen Kaminen ausgefallen sind. Die Erwartungen Seiner Königlichen Hoheit sind nicht nur dadurch weit übertroffen worden, sondern auch seine Wünsche in jeder Hinsicht vollkommen befriedigt worden. In der That scheint das jetzige Arrangement alle Vortheile eines Gasfeuers mit dem freundlichen Anblick eines Kohlenfeuers zu vereinigen. Seine Königliche Hoheit trägt mir daher auf Ihnen noch einmal seinen aufrichtigen Dank für Ihre gefälligen Bemühungen in dieser Angelegenheit auszusprechen, und Sie zu bitten beifol- gendes Portrait als ein Zeichen seiner Anerkennung annehmen zu wollen. Der Prinz hofft, dass sich bald eine Gelegenheit bieten möge, um Ihnen persönlich den Ausdruck seiner Dank- barkeit wiederholen zu können. Mit freundlichen Grüssen bin ich Ihr ergebenster, M. HOLZMANN. Gas as a Heating Agent. Following out the ideas he had so often promulgated, Dr. Siemens continued to urge the importance and benefit of using gas as a heating agent generally; and he took, in connexion with this idea, much interest in the gas manufacture. In June, 1881, he read a Paper on "Gas Supply" before the British Association of Gas Managers, meeting at Bir- mingham. Referring to his well-known advocacy of electric lighting, he said :— I present myself before you both as a rival and a friend: as a rival because I am one of the promoters of electric illumination, CHAP. VIII.] 293 HEATING BY GAS. and as a friend because I have advocated and extended the use of gas for heating purposes during the last twenty years, and am by no means disposed to relinquish my advocacy of gas both as an illuminating and as a heating agent. He explained that although electric lighting must be preferred for lighthouses, halls, and great thoroughfares, yet gas would probably hold its own as a domestic illuminant, owing to its great convenience of management and use, and he described an improved burner, by which the illu- minating power might be much increased. But the principal object of his lecture was to convince gas engineers and gas managers that there was a largely ex- tended future open for the use of coal gas as a heating agent, which, he said, had been far too much neglected hitherto. He recommended the gas companies to encourage this; and he suggested an ingenious plan of dividing the product of the retorts into two kinds of gas, which might be dis- tributed to the public for lighting and heating purposes respectively, with advantages in both respects. He followed up the same subject in lectures about the same time to the Society of Chemical Industry, and to the people of Glasgow, under the auspices of the “Glasgow Science Lectures Association." But he went farther, for he anticipated that the time might come when, by means of some arrangement analo- gous to his gas producer, gas might be made in the coal districts, and supplied by a gigantic system of distribution to the public generally as fuel. This, on a small scale, had been one of the features of the scheme he had promoted in Birmingham in 1863 (see page 155); but it was clearly in advance of the time, it was not understood, and failed to make any impression. But he told the people of Glasgow, in 1881, that their town, with its adjoining coal-field, appeared to be a par- 294 [CHAP. VIII. LAST YEARS. ticularly favourable locality for putting such a plan to a practical trial, and he added that when thus supplied with gaseous fuel, the town would not only possess a clear atmosphere, but would be relieved of the most objection- able portion of the street traffic. And a year later he told the British Association that he thought the time not far distant when both rich and poor would resort to gas as the most convenient, the cleanest, and the cheapest of heating agents, and when raw coal would be seen only at the collieries. In the meantime he endeavoured to show that by some simple modifications of his regenerative furnace, he could apply the gas producing process on a small scale to ordinary steam-boilers and other applications of fuel. He had established some apparatus for this purpose at Sherwood; and only a few days before his death he was hopefully experimenting on a method for the smokeless supply of heat to a steam-boiler, by the aid of a small gas producer. He had told Sir William Thomson that, without waiting for the very highest attain- able economy, he expected, by using the gas from his producer as fuel even on a comparatively small scale, to be able to obtain better economy of coal for motive power than by burning the coal directly under the boiler. Sir William Thomson after relating this adds, “There is something inexpressibly sad, even in respect to a com- paratively small matter like this, to see the active prosecu- tion of an experiment so full of interest and so near to a practical solution suddenly cut short by death." ELECTRIC TELEGRAPHS. At the end of 1880 a change was made in regard to the proprietorship of the Charlton factory. CHAP. VIII.] 295 ELECTRIC LIGHTING. The firm had hitherto belonged to the three brothers, Werner, William, and Carl Siemens, in partnership. This partnership was now dissolved, and the business was trans- ferred to a limited liability company, under the name of Siemens Brothers & Co., Limited. The three brothers re- mained, with Mr. Loeffler, as directors, and Dr. C. W. Sie- mens was the chairman. The firm continued to execute large contracts, among which were several cables across the Atlantic. ELECTRIC LIGHTING. It has been mentioned in the last chapter that so soon as electric lighting became a practical thing it was taken up, energetically, by the Charlton firm. The work done in this way has been of very varied kind, sometimes in supplying the dynamos, or the lamps, or other separate portions of the apparatus essential for the pur- pose; sometimes in undertaking large contracts for entire installations. It must suffice here to mention a few of the most important of the latter cases. British Museum.—This installation of the electric light was made in 1879, and the electric light has since been regularly employed on foggy days, and in extension of the hours of reading in the library, during the winter. The lighting of the reading-room (as used during the first winter, modifications and extensions having been since introduced) was effected by means of four dynamos of medium size, supplying electricity to four inverted pen- dulum lamps of approximately 3000 candle-power each, suspended at a height of about 30 feet from the floor. In other portions of the building fifteen smaller arc lights, each affording a well diffused illumination of 400 candle- power, were distributed; whilst the office, lavatories, &c., 296 [CHAP. VIII. LAST YEARS. were supplied with 40 Swan incandescent lamps of sixteen candle-power each. The current was supplied by means of two alternate current machines. It was stated by the electrician of the British Museum that the maintenance of the apparatus, including fuel, carbons, and attendance for four months, cost six shillings per hour for a total illumi- nation of 18,800 candles. Royal Albert Dock.-The illumination of this dock by means of the electric light was commenced in October, 1880. The lanterns containing the electric lamps are sus- pended from latticed iron posts about 80 feet high, the area illuminated by each lamp being about 9 acres. The distribution of the light is so effected that ships can be docked and undocked with equal facility by night as by day. The total water area illuminated is about 100 acres, and comprises the various docks, several miles of quays, the locks and jetties, the warehouses and sheds both externally and internally, whilst the new hotel adjoining the Gallions station is fitted up with 100 Swan incandescent lamps. Continuous-current dynamo machines are employed, which are distributed over four stations, each worked by a separate steam-engine. A commutator is arranged so that the current of any machine may readily be measured by means of an electro dynamometer and turned on to any lamp, whilst a detector in connection with each lamp serves to warn the attendant should any lamp be acci- dentally extinguished. The Savoy Theatre.-The first application of electricity to the illumination of theatres was made at the Grand Opera House in Paris. Almost simultaneously Mr. D'Oyly Carte determined to light the above theatre. The internal illumination is produced by means of 1158 Swan lights, of which 150 are in the auditorium; 220 are employed for the illumination of the numerous dressing-rooms, corridors and CHAP. VIII.] 297 ELECTRIC LIGHTING. passages belonging to the theatre, while no less than 824 are employed for the lighting of the stage. These lamps, as at first arranged, were worked in parallel circuit in six groups, five of which comprised about 200 lamps each, and the sixth 166 lamps. The current within the theatre is sup- plied by means of six alternate current and six exciting machines, whilst a continuous-current dynamo produces the powerful electric arc suspended outside of the theatre over the principal entrance. Each machine is controlled by a regulating handle, which, by throwing into its cor- responding magnet circuit greater or less resistance, lessens or increases the brightness of the lamps by degrees. This variation in resistance takes place in the circuit exciting the field magnets. When a series of lights is lowered, in- creased resistance is thrown into the circuit of the dynamo machine, which is exciting the magnets of the alternate current generator corresponding to that particular series of lights, the intensity of the magnetic field of the latter machine is thereby reduced, and consequently the currents induced from that field and transmitted to the lamp circuit are diminished in strength; by thus weakening the mag- netic field, the mechanical resistance to rotation is corres- pondingly reduced, and therefore less power is required to drive the machine. The article in Engineering of the 3rd March, 1882, from which the above is abstracted, concludes thus:-" In an artistic and scenic point of view nothing could be more completely successful than the present light- ing of the Savoy Theatre; the illumination is brilliant without being dazzling; and while being slightly whiter than gas, the accusation of 'ghastliness' so often urged against the light of the electric arc can in no way be applied. In addition to this the light is absolutely steady, and, thanks to the enterprise of Mr. D'Oyly Carte, it is now possible for the first time in the history of the modern 298 [CHAP. VIII. LAST YEARS. theatre, to sit for a whole evening and enjoy a dramatic performance in a cool and pure atmosphere. "" Godalming. This is the first town which has combined public and private lighting by electricity in one commercial undertaking, so that electric light is supplied to private houses at a cost approximating that of gas. It was ori- ginally contemplated to use the natural water power of the district; but it was found to be so variable as not to be economically applicable. Near the Town Hall and in some other important positions arc lights are employed, whilst the streets, to the total exclusion of gas, and private houses are lighted up with incandescent lamps. Two electrical machines are used, one to supply the arc lights, and the other incandescent lights, public and private. Two leading wires are arranged in two circuits, the one comprising the six arc lights and their machine, and the other the second electrical machine, and the two mains between which all the incandescent lamps, whether public or private, are inserted. When the occupier of a house wishes to use incandescent lamps, branch wires are connected at suitable places to the main cables and led into the house, a switch being inserted for the purpose of turning on or cutting off the entire supply at will.* There There are nine The Austral Steamship.—The firm also applied electric lighting to ships; one of the largest examples being the Orient Company's steamship of this name. The whole of the public rooms, the engine-room, the pantries, and the passages are lighted by electricity. arc-lights, five of which are in the engine-room and four on deck, the latter having deep conical lanterns, to provide a good light over the hatches when load- ing or unloading. The incandescence lamps, of which * This lighting is at present discontinued, as subscribers enough could not be found. CHAP. VIII.] 299 ELECTRIC RAILWAYS. there are 170 in use, are arranged upon two separate sets of conducting wires, each set being supplied with elec- tricity by a separate steam-engine and electric generator. Arrangements are made by which, should one engine break down, the other can be readily coupled up to drive both generators; such an accident would only extinguish half the lamps in the principal saloons and passages, as one half the lamps are supplied with electricity from one set, and the other half from another set of leading wires. The vessel is divided into sections, each provided with a distinct set of branch wires and keys, which afford means whereby the lamps in any section may be turned on or off inde- pendently of other sections. The safety of each section is ensured by the insertion of a fusible bridge at the junction of each branch wire with its main, the fusible plug melting if more electricity flows through any branch than the wire is intended to convey. ELECTRIC RAILWAYS. We have mentioned in the last chapter Dr. Siemens's remarks (suggested by the Falls of Niagara) on the possi- bility of using the electric current as a means of transmit- ting mechanical power. During the present period the idea became an accomplished fact, the transmission being effected for several practical objects. The most remarkable of these was the application of electricity for the propulsion of trains on a line of Railway. The idea of doing this presented itself to Dr. Werner Siemens as long ago as 1867,* when he discussed, at the * The subject of electric transmission of power, particularly as applied on railways, was fully treated by Mr. Alexander Siemens in a paper laid before the Society of Arts on the 20th May, 1881; and in another paper, in connection with Mr. Edward Hopkinson, on the 11th 300 [CHAP. VIII. LAST YEARS. Paris Exhibition, with other members of the jury, the possibility of so working railways elevated above the houses in towns. But the dynamo-machine was not at that time sufficiently developed to admit of a practical execution of the idea, and when the present more perfect forms were invented, electric lighting monopolized for a time all the attention that was bestowed on the practical application of the machines. In 1878 Werner Siemens was reminded of his original idea by the owner of a coal-mine asking him to scheme a locomotive to draw the coal-waggons in the mine. The result was that he worked out a design, and constructed a small railway on this plan. This was exhibited at a local exhibition in 1879. It was a line having a gauge of one metre, and laid down in a circle 900 yards long. On this a train of three or four carriages was placed, and on the first carriage a medium-sized dynamo-electric machine was so fixed and connected with the axle of one pair of wheels as to give motion thereto. The two rails, being laid on wooden sleepers, were sufficiently insulated to serve for electric conductors. Between these rails was fixed a bar of iron on wooden supports, through which the current was conveyed to the train by means of metallic brushes fixed to the driving carriage, while the return circuit was com- pleted through the rails themselves. At the station the centre bar and two rails were connected electrically with the poles of a dynamo-electric machine, similar in every way to that on the carriage, and which received motion from a steam-engine. Between twenty and thirty persons could be accommo- dated in the carriages, and the conductor, riding on the April, 1883. From these excellent papers, and from Sir William Siemens's lecture (hereafter mentioned), the particulars in the text are chiefly taken. CHAP. VIII.] 30T ELECTRIC RAILWAYS. first one, could, by means of a communicator, start, stop, or reverse the motion at pleasure. The engine exerted 5 horse-power, and the train travelled at 15 to 20 miles an hour. The railway worked for several months, affording great amusement to the visitors at the exhibition. Dr. William Siemens brought this novel application of electric power before the Society of Telegraph Engineers in June, 1880. He expatiated on the capabilities of the plan, particularly one remarkable feature of it, which may be thus described:- When the motion of the train is slow, the force acting on it is at its maximum, and owing to this it starts with a remarkable energy. When the motion increases, the accelerating power diminishes; so that the driving force regulates itself according to the velocity of the train. On an ascending gradient the speed diminishes and the propelling power increases; on on a falling gradient the reverse effect takes place; and in the latter case, if the train runs down by gravity and over-runs, so to speak, the power of the dynamo, the current will serve as a brake to check the speed. In all these particulars the electric motor, therefore, fulfils perfectly, by automatic action, all the func- tions of the driving power on an ordinary locomotive line. The success of the little Berlin railway justified applica- tions on a larger scale; and Messrs. Siemens and Halske laid before the authorities in Berlin a plan for an elevated railway to be so worked; but it was objected to by the Emperor and the inhabitants, and the concession was not granted. Subsequently, however, the firm obtained permission to build a railway, on the ground level, from Lichterfelde, a suburban station on the Berlin-Anhalt Railway, to the Military Academy. It was opened in the spring of 1881 for regular traffic, and has been in use ever since. 302 [CHAP. VIII. LAST YEARS. It is a single line of one metre gauge, a little over 1 English miles long. It is generally worked on the same plan as the model at the exhibition, except that there is no middle rail, one of the ordinary rails being used as the positive, and the other as the negative conductor; and as the currents are of low tension, it is not necessary to provide further insulation than the ordinary wood sleepers. The power is a steam-engine, stationed near to the line, working a dynamo that sends the current along one rail and receives it from the other. There is one car, like an ordinary tramcar, carrying twenty persons. The other dynamo on the carriage is placed underneath the car, and transmits its movement to the whole by means of spiral steel springs. The tires of the wheels are insulated from their axles, and are in electrical connection with brass rings fastened on the axles, but insulated from them. Contact brushes press against these brass rings, and from them the current is conducted to the dynamo machine, and sets it in motion. The speed is limited by local regulations to 20 kilometres (12 English miles) an hour; but it could run at double this speed with perfect safety. The line has worked since 1881 without hitch or acci- dent of any kind. Messrs. Siemens & Halske have also applied the system to haulage in mines, at Zaukerode, in Saxony. In this latter case the rails could not be used for the conductors, as they were being frequently meddled with; but the current was taken along the roof of the workings by an inverted T-iron rail, on which a contact carriage, connected with the engine by a flexible cable, was made freely to slide. The engine could draw 8 tons at 7 miles an hour. A short line of the same kind was also laid down at the CHAP. VIII.] 303 ELECTRIC RAILWAYS. Paris Electric Exhibition of 1881, when cars ran at regular intervals from the Place de la Concorde to the Exhibition building, and 95,000 passengers were conveyed in seven weeks upon this novel railway. Here, also, the overhead conduction was applied, as more out of the way of the crowd. Another line was fixed at the Electrical Exhibition at Vienna, in 1883. This was larger than the Paris one; but here the rails formed the conductors. The length was one mile. There were two cars, carrying 100 persons, and a speed could be attained of 20 miles an hour. A larger application has been made by the London firm to a railway in the north of Ireland. In 1878 a concession was granted to the Ulster Steam Tramway Company for making a tramway from Portrush (the terminus of the Belfast and Northern Counties Railway) to Bush Mills, in the Bush Valley, 6 miles distant, to be worked by steam. The company was unable to raise the capital, and became. insolvent. An Act of Parliament was then obtained, in 1880, by two brothers of the name of Traill, and the line was completed and opened for traffic by steam cars in January, 1883. Messrs. Traill, however, having heard of the success of the electrical railway, had prudently obtained authority in their Act to use electricity; and, as there was abundant water-power available in the neighbourhood, they consulted Dr. Siemens as to the advisability of adopting it. Dr. Siemens willingly joined in the undertaking, and the work was put in hand. While making sure of their traffic by their steam-cars, the proprietors, in conjunction with Messrs. Siemens, who were ably represented on the spot by Dr. Edward Hopkin- son, conducted a series of experiments as to the best way 304 [CHAP. VIII, LAST YEARS. of applying the power. It was at first attempted to convey the electric current along the line by the ordinary rails: This answered very well for nearly two miles; but beyond that the leakage became too great, and another plan was adopted. In this the two rails, 3 feet apart, are not insulated from the ground, but being joined electrically by means of copper staples, they form the return circuit, the current being con- veyed to the car through a T-iron placed on short standards, and insulated by means of caps of non-conducting material. When a gap occurs, such as at a cross road, the T-iron is stopped and commenced again at the other side of the gap, the ends being connected by an insulated conductor below ground. In order to span this gap there are two collecting brushes attached to the car, one in front and the other towards the back, and the gap being a little less than the distance between the two brushes, the one brush catches the opposite side before the other one leaves. This simple arrangement gets over the difficulty of crossing bye- roads. The line was laid with steep gradients varying from I in 45 to 1 in 30, including a long incline of 1 in 38. The electric arrangements being completed on the altered plan, a first start was made with the new power in No- vember, 1882, and although the trial took place in a heavy down-pour of rain, the insulation did not fail. Further experiments and adjustments were however required, and it was some months before the whole was got into good order. On the 18th March, 1883, Dr. Siemens, writing to Sir William Thomson, said :— The electric car has beaten the steam-car in pulling a loaded waggon up the long incline of 1 in 38, and we shall soon be ready for public traffic. The present insulation is very perfect, CHAP. VIII.] 305 ELECTRIC RAILWAYS. 4 and will enable us to increase the electric pressure very considerably. In the preliminary trials the electric current was pro- duced by a dynamo worked by a small stationary steam- engine of about 15 horse-power at Portrush. But as soon as Messrs. Traill saw that the application was a success, they took steps to carry out the design they had from the first in view, namely, to take advantage of water-power in the neighbourhood. There was a salmon-leap on the river Bush, about a mile from the Bush Mills end of the stream; and after some delay by legal proceedings, the control of the water- power was secured. Two turbines were obtained from America, capable of giving out about 45 horse-power each, and were made to work the dynamo, the current passing by an underground cable to the line. As it was thought that the introduction of this railway would be an event of importance for the country, appli- cation was made to the Lord Lieutenant, Earl Spencer, asking him if he would honour the proprietors by opening it. His lordship's consent was given in the following note, in which the kind consideration for Sir William Siemens and the desire for his presence are noteworthy :- DEAR SIR WILLIAM,- ALTHORP, NORTHAMPTON, 1 August, 1883. Mr. Traill is anxious that the opening of the Electric Railway at Portrush shall be on Friday, September 14th, rather than on Monday, September 17th. I am ready for either day, but it must be settled so as to secure your presence. I have a preference for the earlier date, and I expect that Monday is not a very convenient day for visitors. Yours truly, SPENCER. X 306 [CHAP. VIII. LAST YEARS. Subsequent alteration in the time had to be made, and the railway was formally opened on the 28th of September, 1883. Sir William Siemens was present, accompanied by his local coadjutors, his friends Sir William Thomson, Sir Frederick Bramwell, the Astronomer Royal of Ireland, and others interested in the work. It has since been regularly used for public traffic. The working speed is limited by the Board of Trade Regulation to 10 miles an hour, but it will run on a level at 12 miles. Some fear was entertained of danger by persons touching the exposed rails through which the current was passing; but it was found that no evil could occur so long as the electro-motive force did not exceed a certain amount (250 volts), and self-acting arrangements were adopted to secure this as a maximum tension. The leakage by defective insulation does not exceed 5 per cent. when four cars are running. The working cost is found to be 25 per cent. less than with steam locomotive power, taking no account of the saving by the less destructive action on the permanent way. Since Sir William Siemens's death, Messrs. Traill have extended the railway from Bush Mills to Derrock, some miles farther, which brings it to the immediate neighbour- hood of the scenery of the Giants' Causeway." * It is clear, therefore, that the feasibility of working rail- ways by the electric transmission of power has been amply proved. Dr. Siemens did not pretend that this mode of propulsion could compete with the steam locomotive for railways generally, but he did look forward to a consider- able use for it in cases where exceptional circumstances might justify its application and give it a preference. A little Electric Railway of a mile long was constructed and opened in August, 1883, by Mr. Magnus Volk, on the shore under the East Cliff at Brighton, Messrs. Siemens's dynamos and motors being used. CHAP. VIII.] 307 ELECTRIC PROPULSION. It would, he conceived, be peculiarly applicable to tram- ways within populous districts; but in such places the insulated conductors might involve a serious difficulty. He considered it would be better in these cases to resort to the storage of electric energy in secondary batteries, which might be carried in the car itself. In many cases these might be charged by the dynamo when the car was running down hill. In like manner, for the propulsion of boats, the secondary battery might be used and would form part of the keel-weight. One of the greatest advantages of electric propulsion would be the entire immunity from all the evils of the pro- ducts of combustion. On this latter ground, Dr. Siemens predicted its probable use in long tunnels or underground lines, where the steam locomotive had the great disadvan- tage of fouling the air. He particularly alluded to the underground railways in the metropolis, in regard to which he said :- Under these circumstances it seems to me almost a pity that on the Embankment there should be made that series of unsightly and noisome ventilators to disembarrass the underground railway of steam and products of combustion, when it can be clearly demonstrated that electric propulsion would, for such lines, be not only the most agreeable, but also the cheapest mode of traction. Dr. Siemens was not satisfied with talking about this matter; as usual with him he tried to get his idea carried into practice. About 1863 a scheme had been launched for connecting Charing Cross with Waterloo Station by a pneumatic rail- way, with a tunnel under the Thames. The works were commenced, but were soon after abandoned. The scheme was taken up again in a modified form, and an Act was obtained for it in the year 1882. It was proposed to con- X 2 308 [CHAP. VIII. LAST YEARS. struct a double line of railway from a point near Charing Cross, passing under the Embankment and the river Thames, and terminating at Vine Street, Lambeth, under the loop-line station of the Waterloo terminus. Dr. Siemens took advantage of this scheme to endeavour to introduce the electric system into it, and he prepared plans for the whole working of the railway in all details. But there was a difficulty in raising money for the under- taking, and the work did not proceed. OTHER APPLICATIONS OF ELECTRICAL POWER. The electric transmission of power has also been applied to other purposes. It has been used to propel boats, to drive tricyles; and the attempt has been made, with fair success, to effect the propulsion and steering of balloons through electric agency.* It has also been used for lifts and hoists, to work pumps, to turn ventilating fans in collieries, to move machines in engineering shops, and for many other purposes. Indeed it has been pointed out that at some future time electric mains may be made to run along our streets, which will be supplied from central stations, and from which currents of electricity may be drawn, as water and gas are now. These may be used either for lighting or for trans- mitting power, and in the latter case they may not only serve for the purposes of trade, but by the extreme sim- plicity of the apparatus required, they may bring mechanical power into use for small purposes to a much greater extent than at present. In the United States the application of electric motors See Papers by the author of this work in the Minutes of Proceed- ings of the Institution of Civil Engineers, Vols. 67 (1882), and 81 (1885). CHAP. VIII.] 309 ELECTRIC POWER. is already rivalling, and will soon excel in importance the application of electricity to lighting purposes. At Boston hundreds of motors are supplied by electricity from central stations, and in many other towns the number is very great. It has been proposed to use electric transmission in large mills to supersede the use of shafting and belts, which not only waste an enormous amount of engine-power, but are very costly to construct and maintain. In Switzerland, where water-power is plentiful, its utiliz- ation by electricity is already largely used. Towns are lighted and supplied with power from sources miles away; and in Geneva, within a radius of a mile and a quarter there are no fewer than 175 motors at work, varying from to 70 horses' power. The idea of Sir William Siemens of making use in this way of the power from Niagara falls, though considered only fanciful at the time, seems likely to be in some degree realized; for it is stated that plant is being put down there to distribute the power to neighbouring towns, including Buffalo, which is twenty miles distant. The amount of power to be so distributed is stated at 15,000 horse power, of which 10,000 is contracted for at £3 per horse power per annum for Buffalo alone.* Lecture by Dr. Siemens.-In the year 1883 the Council of the Institution of Civil Engineers determined to offer to their members a course of six lectures on the "Practical Applications of Electricity," and they were only too glad to take advantage of Dr. Siemens's willingness to com- municate information on a subject so peculiarly his own. The branch he chose was "The Electrical Transmission See Paper by Mr. Wm. Geipel, communicated to the Institution of Mechanical Engineers, 1888. 310 [CHAP. VIII. LAST YEARS. and Storage of Power," and the Lecture thereon was delivered at the Institution on the 15th March, 1883. After a notice of the history of the subject, he gave a full explanation of the nature of the dynamo-electric machine in its various forms, and of its mode of acting both in lighting and in transmitting power. The lecture was illustrated by machines and apparatus in action. He exhibited the manner in which several applications of the dynamo had been carried out, and dwelt at some length on the construction, prospects, and advantages of the electric railway. In this lecture he also showed an instrument he had just invented to indicate the electric energy traversing a circuit. In writing to Sir William Thomson after the lecture he said: The Watt Meter behaved very well, enabling me to give the power expended in pumping water = 36 horse-power. About the middle of the lecture the speaker was inter- rupted by a violent report, resulting in the breakage of some glass in the dome of the theatre, and of windows at the back of the building, This was caused by the memor- able explosion of dynamite on the premises of the Local Government Board in Whitehall, a short distance away. Dr. Siemens, however, after a short pause, being assured that no danger menaced the audience, went on with his lecture with perfect coolness and self-command. The following is his own notice of this interruption, written to Sir William Thomson a day or two later :— 18th March, 1883. The experiments succeeded pretty well, but in the midst of my discourse a terrific explosion occurred, followed by the noise of falling glass in the dome and the windows towards the north. My first fear was that the portable engine-boiler [which was providing CHAP. VIII.] 311 ELECTRIC HEATING. the current for his experiments] had exploded, but after a few seconds I was satisfied that my current was still in the leads; the secretary called out that the building was safe, and I continued after scarcely a minute's interruption. Fortunately the glass fell from the dome windows to the outside, or the momentary panic might not have been got under without serious consequences, for 650 persons were closely packed in the room. ELECTRIC HEATING. The great heat given off by the Voltaic arc had been, like its light, a matter of observation at a very early period, but there had been no serious attempts to make it useful. When, however, the dynamo-electric apparatus had brought powerful currents into action, Dr. Siemens set himself to solve the problem of applying their heat-giving power to practical ends. He knew something about heat, and he was about the best person to determine what a new source of heat would be likely to do. He saw at once that the great feature of the electric heat was not its quantity, but its intensity. It was not suited, like the combustion of ordinary fuel, to communicate moderate temperatures to large masses of material, but it was able to operate on smaller substances, with a calorific energy probably exceeding any other kind of action. In pursuance of this idea, he proposed to form with the arc an electrical furnace, which he believed would, with great facility, produce melting effects hitherto obtainable only on a very minute scale, or with the aid of very costly means. The apparatus by which he proposed to do this was patented on the 27th May, 1879; the patent (which contained some other electric matters) being for "Improved means and Apparatus for producing Light and Heat by 312 [CHAP. VIII. LAST YEARS. Electricity." The claim bearing on this subject was as follows:- The use, for applying the heat of the voltaic arc, of a crucible having introduced into it terminals, such as are employed in electric lamps, adjusted so that the arc is produced and maintained within the crucible. There was also a modified claim, for the case where the substance to be acted on was used as a conductor. He described the apparatus to the Society of Telegraph Engineers in a Paper read June 3, 1880. After mentioning the means previously at the disposal of metallurgists, such as the oxy-hydrogen blast, and his own Regenerative Gas Furnace, he went on to say- The temperature allowable in both furnaces is limited by the power of complete dissociation of carbonic acid and aqueous vapour, which may be estimated at from 2500° to 2800° Cent. But long before this has been reached, combustion becomes so sluggish that the losses of heat by radiation balance the pro- duction by combustion, and thus prevent further increase of the temperature. It is to the electric arc, therefore, that we must look for the attainment of a temperature exceeding this. Professor Dewar quite recently, in experimenting with the dynamo-electric current, has shown . . . . that the temperature attained was not much inferior to that of the sun. My present object is to show that the electric arc is not only capable of producing a very high temperature within a focus or extremely contracted space, but also such larger effects, with comparatively moderate expenditure of energy, as will render it useful in the arts for fusing platinum, iridium, steel, or iron, or for effecting such reactions or decompositions as require for their accomplishment an intense degree of heat, coupled with freedom from such disturbing influences as are inseparable from a furnace worked by the combustion of carbonaceous material. CHAP. VIII.] 313 ELECTRIC FURNACE. Dr. Siemens exhibited and explained the furnace he had contrived for the purpose. It consisted of an electrical arc, produced by a current from a dynamo-electric machine, caused to play, within a crucible, upon the material to be acted upon, and capable of regulation at pleasure. The advantages of such a furnace were stated to be that the temperature attainable was theoretically un- limited, and was practically very high, even with ordinary refractory materials; that the heat was developed im- mediately in the material to be fused, instead of having first passed through the containing vessel; that the fusion was effected in a perfectly neutral atmosphere, and that the operation could be carried on in a laboratory without much preparation, and under the eye of the operator. He believed these would render the furnace a useful agent at temperatures and under conditions which it had been hitherto impossible to secure. Many striking effects of the furnace were described. Among them 8 lbs. of platinum, a metal very difficult of fusion, were rendered perfectly liquid in about a quarter of an hour; and tungsten, which had never previously been melted, showed, in the electric fire, unmistakeable signs of fusion. The furnace was exhibited at the Electrical Exhibition in Paris in 1881, and was a special object of interest to the Prince of Wales and members of the British Commission as well as to the general public. The furnace has been lately taken up for the production of aluminium, and its use is expected much to cheapen this valuable metal. It has also been applied with great advantage to the welding of steel.* * Geipel, loc. cit. 314 [CHAP. VIII. LAST YEARS. VEGETATION UNDER ELECTRIC LIGHT. In the course of Dr. Siemens's study of the properties of the Electric Light, it occurred to him that it would be worth while to inquire how far this light might be made to supply the place of the sun in promoting vegetation, and in stimulating the growth of plants and fruits. About the beginning of 1878 he mentioned the subject to Sir Joseph Hooker, at that time President of the Royal Society and Director of the Botanic Gardens at Kew; but Sir Joseph appears to have been cautious in giving an opinion, and so nothing was done, although Dr. Siemens continued to turn the matter over in his own mind. In the meantime, the electric light was being applied to the Albert Hall and adjoining buildings; and on the evening of the 27th of May, 1879, a fête was given in the grounds of the Horticultural Society, during which a splendid series of electric lamps were established in the conservatory, brilliantly illuminating the trees and plants it contained. This effect made a great impression on the mind of Dr. Maxwell Masters, the Editor of the chief horticultural periodical, the Gardeners' Chronicle. The next day Dr. Masters wrote to Dr. Siemens as follows: DEAR SIR,- THE GARDENERS' CHRONICLE OFFICE, 41, WellingtON STREET, Strand, W.C. LONDON, May 28th, 1879. : I have for some time past been much interested in the possible future application of the electric light for forcing purposes, and the brilliant illumination of the conservatory of the Royal Horticultural Gardens last night induces me to trouble you with this note. : You are aware that for forcing purposes the gardener can re ulate heat and moisture at will, but the dull days of winter are CHAP. VIII.] 315 ELECTRIC HORTICULTURE. a great obstacle. Now, if by the electric light time could be saved in the length of time required to force grapes, &c., and flavour could be secured, a very great advantage would be secured, and one of no little commercial importance. Would it be possible, now that the apparatus is at Kensington, to contrive a few simple experiments on the action of the light on plants; for instance, to see whether tulips or dandelions, once closed, would re-open by exposure to the electric light? Whether their period of expansion could be lengthened? Whether the decomposition of carbonic acid gas could be effected as under the solar ray, &c.? I am no electrician, and so I do not know how far such experi- ments would be practicable; but they would seem to be easy, and if so, the possible future application of the electric light for the purposes I have mentioned would be rendered certain. Growth can take place with little or no light, but the formation of chloro- phyll and other secretions demands exposure to solar or-?-to electric light. Pray pardon the intrusion; I sought you fruitlessly last night, but even had I met you, a Conversazione is not the place to talk over a scientific experiment. If it were not unduly intruding on your time I would gladly call on you at some time to explain my views. Faithfully yours, MAXWELL T. MASTERS, M.D., F.R.S., Editor of the Gardeners' Chronicle. To this letter Dr. Siemens replied (1 June, 1879), stating that he had spoken to Sir Joseph Hooker on the subject some time before, and adding- I quite agree with you in believing that the electric light will be found very efficacious as a substitute for solar light in promoting the growth of plants, and the ripening of fruit. Like solar light, the ray is sufficiently intense to break up carbonic acid and produce woody fibre. The electric light is peculiarly rich in actinic and blue rays, which we may suppose to be most efficacious for the purpose. 316 [CHAP. VIII. LAST YEARS. If I were a botanist as well as an electrician I would before this have tried an experiment; but seeing that you are struck with the same idea, I should be willing to co-operate with you in putting the question to a practical test. Dr. Siemens soon afterwards had an interview with Dr. Masters, and it was arranged they should have a meeting with Sir Joseph Hooker and confer with him. This meeting took place, and the result was that Dr. Siemens took steps to bring the matter into a practical shape. He determined to make a series of experiments at his country house at Tunbridge Wells, where he had already fitted up a complete electric installation, and he proceeded to design the electric and gardening arrange- ments necessary for the purpose. But these took still much time to complete, and it was the beginning of the year 1880 before the observations actually began. They had sufficiently advanced in the spring to enable him to make a communication to the Royal Society on 4th March, 1880, entitled— "On the influence of Electric Light on Vegetation, and on certain Physical Principles involved." After alluding to earlier observations upon the dissocia- tion of water and carbonic acid, and the effect of radiant energy upon them, he went on to say: The vast development of vegetation proves that dissociation is accomplished freely within the leaf-cells of plants, in which both water and carbonic acid are broken up in order that chlorophyll, starch, and cellulose may be formed. It is well known that this reaction depends upon solar radiation; but the question may fairly be asked whether it is confined to that agency, or whether other sources of light and heat, which in common with the sun exceed the temperature of dissociation, may not be called into requisition, in order to continue the action of growth, when that great luminary has set, or is hidden behind clouds? CHAP. VIII.] 317 ELECTRIC HORTICULTURE. He then described the experiments, which were continued at Sherwood for many months, on plants of various kinds, and treated under various circumstances. They led to the following conclusions :- 1. That electric light is efficacious in producing chlorophyll in the leaves of plants, and in promoting growth. 2. That an electric centre of light equal to 1400 candles, placed at a distance of two metres from growing plants, appeared to be equal in effect to average daylight at this season of the year, but that more economical effects can be attained by more powerful light centres. 3. That the carbonic acid and nitrogenous compounds gene- rated in diminutive quantities in the electric arc produce no sensible deleterious effects upon plants enclosed in the same space. 4. That plants do not appear to require a period of rest during the twenty-four hours of the day, but make increased and vigorous progress if subjected during daytime to sunlight, and during the night to electric light. 5. That the radiation of heat from powerful electric arcs can be made available to counteract the effect of night frost, and is likely to promote the setting and ripening of fruit in the open air. 6. That while under the influence of electric light plants can sustain increased stove heat without collapsing, a circumstance favourable to forcing by electric light. 7. That the expense of electro-horticulture depends mainly upon the cost of mechanical energy, and is very moderate where natural sources of such energy, such as waterfalls, can be made available. Dr. Maxwell Masters was present at the reading of the paper, and on the following day he wrote to Dr. Siemens, expressing his delight, and asking permission to publish the experiments in his journal, adding: All this confirms the impression that sooner or later the light 318 [CHAP. VIII. LAST YEARS. will be used for forcing purposes; for ultimately even the cost will prove no obstacle, at least in a large establishment where forcing is carried on on a large scale. Dr. Siemens invited Dr. Masters to see the process at Sherwood, and other letters followed, in one of which Dr. Masters said :— I fully believe you will inaugurate a new era in "forcing," a matter of considerable commercial importance. On March 18, Dr. Siemens sent sent to the Royal Society a supplement to his paper, extending his results to the ripening of fruits. At a later time, a bunch of bananas so treated were shewn to the Scientific Committee of the Royal Horticultural Society, and elicited a formal letter of thanks from them. In June, 1880, he explained the subject fully to the Society of Telegraph Engineers, dwelling particularly on the electric details of the apparatus and processes used. At the meeting of the British Association in September, 1881, Dr. Siemens gave further particulars of more ex- tended horticultural and agricultural experiments, which led him to think that the time was not far distant when the electric light would be found a valuable adjunct to these operations. He also described how the power provided for producing the electric current might be utilized profitably for other objects connected with horticultural and agricultural work, and thus the expense reduced. Dr. Siemens received many letters on this subject, a few of which may be quoted. CHAP. VIII.] ELECTRIC HORTICULTURE. 319 MY DEAR SIEMENS,— GLASGOW UNIVERSITY, April 10th, 1880. We read with the greatest interest the accounts of your gardening by electric light. It is delightful to see these first trials. so satisfactory and so full of promise. I hope you will persevere. Have you tried more experiments on "the sun putting out the fire?" Would not the electric light have a similar effect, and to even a greater degree? Richness in rays from blue to ultra- violet, seems to be characteristic of the electric light, and to it may be due some of its good effects on vegetation, and its “ non- burning" effect on the face,* and the chemical effects which you found to be produced by sunlight on the combustion of vapours in a lamp might very probably be chiefly due to such rays. Yours, very truly, WILLIAM THOMSON. 4, ADDISON GARDENS, 23rd September, 1881. Dr. Rae has received and read with much pleasure and in- struction Dr. C. W. Siemens's application of electric energy to Horticulture and Agriculture. The effects appear wonderful, and may in a great measure revolutionize the operations of the gardener and farmer, especially as the motive power can be profitably utilized during the hours of daylight. In the Arctic regions, crops of anti-scorbutic could be easily raised on board ship by this plan. From Mons. J. A. BARRAL, Life Secretary to the Société Nationale d'Agriculture de France.

Alors j'aurai l'honneur de vous rendre visite. * Sir William Thomson writes (17 Aug. 1888), "Later experience has shown that it was a mistake to suppose that the electric light had a 'non-burning' effect on the face. It is now well known that those who work much in close proximity to electric arc lamps become 'sun- burned' very much as if they had been exposed to natural sunshine." 320 [CHAP, VIII. LAST YEARS. “.

The publication of these vegetation experiments gave rise to the following clever epigram, which appeared in one of the numbers of Nature. Quis veterum vidit plantas sine sole virentes? Germinat en semen Siementis lumine claro! ELECTRIC UNITS. Dr. Siemens took an active part in the proceedings that were taken to settle the names and values of the Units used in modern electric calculations. He aided in all the * The pun is untranslateable, but the sense may be thus expressed: Who ever heard that plants would grow Without the sun's inspiring glow?

He mentioned the subject somewhat fully in his address to the British Association in 1882, and he wrote various papers about it elsewhere. In 1883 he was elected chair- man of a committee appointed by the Science and Art Department to advise on the subject, a post which he retained until his death. MISCELLANEOUS MATTERS. The Sun. One of the chief topics that occupied Dr. Siemens's mind during this period, was a bold speculation which, though of a highly scientific character, differed from his more usual subjects of thought in that it had no immediate practical bearing; it was no less a matter than the con- stitution of the sun, and the nature of the solar energy. His researches into light and heat had led him to think deeply about the great source of both in the centre of the solar system. He had already, in the lecture on Fuel, given before the British Association in 1873, made some thought- ful remarks on the nature of combustion, and the utilization of different forms of energy; and he had foreshadowed some ideas as to the sun. These had excited attention, and after further careful study, and consultation with the most eminent physicists of his acquaintance, he now carried them further, pushing them into the region of daring hypothesis; and he ventured to submit to the Royal Society, on the 20th February, 1882, a paper "On the Conservation of the Solar Energy." Y 322 [CHAP. VIII. LAST YEARS. He said in a letter afterwards addressed to the President :- In putting forward my perhaps somewhat daring hypothesis, I was animated by the feeling that although not prepared certainly to discuss intricate questions of solar physics upon equal terms with some of my hearers, I possessed special advantages in having given a life-long attention to questions of combustion, and to the utilization of different forms of energy upon a compara- tively large scale. This led me to look upon the sun in the light of a vast piece of apparatus, worked upon principles such as could be observed and appreciated at their real value in terrestrial practice. In the paper in question, he began by pointing out what an enormous amount of heat was continually being radiated away from the sun, equivalent to the perfect combustion, every 36 hours, of a mass of coal as great as our earth. Of this, he estimated that the planets would only intercept about one 225-millionth part, leaving all the rest to vanish away into infinite space, and be lost to the system of which the sun was the centre. He remarked that it had long been a source of wonder to natural philosophers how so prodigious an amount could be given off, year after year, without any appreciable diminution of the sun's temperature. Various theories had been offered in explanation, such as that of the supply being kept up by meteors falling into the sun, or that of the gradual shrinkage of the sun's volume. But these were all more or less open to objection; and he ventured to put forward a new explanation which he conceived would be more satisfactory. This explanation was found in three postulates. He assumed, in the first place, that gaseous matters, particularly aqueous vapour and carbon compounds, were CHAP. VIII.] 323 THE SUN. present in a highly attenuated state, in stellar and inter- planetary space, an assumption for which he brought forward several ingenious arguments. He next conceived that these gases were capable of being dissociated by the radiant solar energy. And thirdly, he attributed a peculiar effect on these dissociated vapours, to the mechanical action of the sun's rotation. He likened this action to that of the well-known centrifugal blowing fan, which, revolving with great velocity, draws air in near its axis, and ejects it at its circumference. In this manner he argued that the effect of the sun's rotation would be to draw in the dissociated vapours upon its polar surfaces, and so to subject them to intense combustion, after which they would be again ejected into space from the quickly revolving sun's equator. This "fan-like action," as he called it, when combined with the chemical phenomena, he considered to offer a solution of the problem of the maintenance of energy. He considered, in fact, that the sun might be regarded as a gigantic specimen of one of his own regenerative gas furnaces, with, however, the unusual condition that the same materials of combustion were used over and over again. He carefully avoided the charge of having broached a "perpetual motion " impossibility, for he admitted there must be some loss of energy, without which indeed his assumed process could not go on; but he opposed the idea of enormous waste, an idea that was as repulsive to him in the solar system as it had been in the manufacturing economy. He said, in concluding the paper- If these conditions could be substantiated, we should gain the satisfaction that our Solar System would no longer impress us with the idea of prodigious waste through dissipation of energy into space, but rather with that of well-ordered, self-sustaining Y 2 324 [CHAP. VIII. LAST YEARS. action, capable of continuing solar radiation to a very remote future. An article by Dr. Siemens, embodying a popular account of his theory, was inserted in the Nineteenth Century for April, and notices of the communication were widely pub- lished in England, and by translations on the continent also. The theory was warmly discussed, and many scien- tific men hastened to record their criticisms upon it; these were taken in very good part and courteously answered by Dr. Siemens. The following letters on the subject will probably be interesting:- A friend wrote, under date 4th March, 1882 :- I had a very long and interesting talk with Lord Sherbrooke (Mr. Lowe) this morning. He was immensely interested in what I told him of your views, and repented that he had not been your pupil instead of learning so much Latin, Greek, and Mathematics; and he spoke of you, and those who are working with you to enlarge our sphere of knowledge, as "the salt of the earth”—high praise from such a critic. 15, ROYAL TERRACE, EDINBurgh, DEAR MR. Siemens,– 5th April, 1882. Many thanks for the copy of the Nineteenth Century edition of your glorious Sun-paper.

And to which I willingly add, as a further testimony from a small onlooker, as to the righteousness of your ways, that if Addison had lived earlier, Sir Isaac would have, or was the style of man to have, quoted the very verse with which you wind up.

Dumas, sécré- taire perpetuel de l'Institut, a demandé avec instance, à M. Gauthier Villars, de vouloir bien laisser insérer dans les Annales de Physique et de Chimie, la traduction de votre mémoire sur l'énergie solaire, et que je me suis empressé de répondre à son désir. Permettez-moi de vous féliciter de cette marque d'approbation, qui vous est donnée, très chaleureusement, par un de nos savants les plus illustres, et de vous dire combien j'en suis heureux. Croyez moi bien, cher monsieur, votre tout dévoué, G. RICHARD. Dr. W. D. Carpenter, in an article in Knowledge, published March 17th, 1882, said:- Dr. Siemens's most ingenious speculation, whatever may be its ultimate issue, must be accounted one of the highest and most brilliant flights that the scientific imagination has ever made. At the Anniversary Meeting of the Royal Society on the 30th November, 1882, the President, Mr. Spottiswoode, made a kind of summing-up of the controversy in his annual address, when he said :— Nor must I omit mention of Dr. C. W. Siemens's bold and original theory of the conservation of solar energy, which has already given rise to so much discussion. It will be sufficient for me here to say that upon the questions therein raised the last 326 [CHAP. VIII. LAST YEARS. word has been by no means said; and that whether the theory be ultimately established, or whether, like a Phoenix, it shall hereafter give rise to some other outcome from its own ashes, it will ever be remembered as having set many active minds at work, and will always have a place in the history of Solar Physics. In April, 1883, Sir William republished the original paper, together with the criticisms and his replies, and with other matters bearing on the subject, in a volume dedicated to the President. In the letter of dedication, he cordially accepted the position Mr. Spottiswoode had assigned to the question at issue, and added:- All things considered, I have every reason to be satisfied with the interest that has been taken in the question I have ventured to bring forward. The following letters relate to this republication : ROYAL OBSERVATORY, EDINBURGH, DEAR SIR WILLIAM SIEMENS,— 19th April, 1883. Many thanks for your obliging presentation of your new volume on the Conservation of Solar Energy.

THE WHITE HOUSE, CROOM'S HILL, GREENWICH PARK, S.E., MY DEAR SIR,— April 25th, 1883. A note which I addressed to you three days ago vanished mysteriously (with others) before reaching the post, and its purport was to acknowledge your kind recollection in sending to me a copy of your "Collection of Papers and Discussions on the Conservation of Solar Energy." CHAP. VIII.] 327 THE SUN. Some months ago I had the pleasure of a short correspondence with you on this subject. I pointed out some mechanical con- siderations regarding the effect of rotation. But the question has widened much into gaseous theories, and more extended cosmology, into which I do not venture boldly. On mere mechanical principles, I do not despair of explaining conservation of the vis viva of an issue of a vibratory ray, by a species of reflection from a gradual diminution of density of the vibrating medium. There is a phenomenon in some measure analogous to it which I have myself observed and brought to the attention of other observers, the interior echo from the open mouth of a tall chimney. Pray try this when one of your chimneys is open at the top and accessible at the bottom. I beg you to convey my respectful compliments to Lady Siemens, and am, My dear Sir, yours very truly, SIR CHARLES W. SIEMENS, D.C.L., LL.D., &C., &C. G. B. AIRY. None of the arguments brought against Sir William's theory seemed powerful enough to shake his faith in it; for, on the contrary, during the few remaining months of his life, he continued to gather, from new scientific data, what he considered further evidence in its favour. An instance of this was shewn in another paper which he presented to the Royal Society on the 25th of April, 1883, entitled :-" On the Dependence of Radiation on Tempe- rature." In the course of his solar investigations, he had remarked the obscurity of the laws of radiation, and the con- sequent uncertainty and discrepancy as to the solar tempera- ture, and he determined to institute a personal investigation to throw light on the matter, conceiving that the facilities for such an investigation, by reason of the latest electrical and spectroscopic discoveries, were greater than at any former time. He described his experiments and results so far as he had gone, but some points were left open on 328 [CHAP. VIII. LAST YEARS. which he stated his "intention to make further investi- gations," an intention which, alas! he was not destined to carry into execution. Two days later, on the 27th of April, he delivered a lecture on the same points at the Royal Institution, and it was printed in Vol. X. of their proceedings. These two communications were the last published documents that emanated from his pen, and they clearly shew the tendency of his mind in his later days towards abstruse scientific studies. One of the ablest notices of Dr. Siemens's book appeared in the Saturday Review of 28th July, 1883. While generally highly complimentary to Dr. Siemens's investigations, it concluded thus:- It seems to us therefore that on the whole the probabilities are decidedly against the truth of the theory; though in the words of the great scientific leader we have so lately lost, "Upon the questions therein raised the last word has by no means been said.” The publication of the book whose contents we have been criticising has put the whole question in a nutshell, and it should be read by all those who are interested in the progress of solar physics. The Indian Engineering College. Dr. Siemens was never so thoroughly happy as when, after having studied theories, he could reduce them to practice; in fact, one of the reasons why he took so much pleasure in his work was that it was of a kind that enabled him to do so. In the last year of his life, he had an unlooked for opportunity of carrying out this principle, in regard to the education which should be given to students in his own profession, Civil Engineering. This was afforded by a connexion which he formed with the authorities of CHAP. VIII.] 329 THE INDIAN COLLEGE. the Indian Engineering College at Cooper's Hill, near Staines. The College had been founded by Government, under the auspices of the Council of India, in 1871, and its object was to give to a number of carefully selected pupils, under competent professors, a preparatory technical edu- cation to fit them, in conjunction with further practical instruction, for becoming engineers, and serving as such on public works in India. The system was found to answer well, and had been in successful action for seven years, sending out annually about forty well qualified recruits :—when, in 1878, the Indian Government, from imperative financial reasons, found it necessary to curtail largely the expenditure on public works, and, as a consequence, to diminish the annual supply of students by about one half. The continued maintenance of the college under these new circumstances, soon became a financial question, which remained unsettled for two or three years. In 1879, the President, Colonel. Chesney, R.E., induced the Govern- ment to institute a Board of Visitors, which should, in addition to certain representatives of the Government, com- prise some influential civil engineers who might advise on the affairs of the college; and especially on what changes in its constitution and curriculum would make it attractive to students who, while able to afford the expensive education, were willing to look for a professional career elsewhere than in the service of the Indian Government. Of this Board, Dr. Siemens became one of the earliest and most influential and active members; and he did not hesitate to express the opinion that, with a wider cur- riculum, the vacancies left in the college by the new policy of the Indian Government, would be easily filled by students of the class mentioned. 330 [CHAP. VIII. LAST YEARS. Soon after this, Colonel Chesney was succeeded by General Sir Alexander Taylor, K.C.B., R.E., who induced the Government to request the Board of Visitors to examine and report upon the best means of attaining the end desired. In the proceedings which followed during the next three years, down to 1883, it was Dr. Siemens who took, chiefly, the initiative in proposing various important changes; and with the earnest support and intervention of Sir John Fowler, Mr. W. H. Barlow, and the chairman, Sir R. Temple, he prevailed upon the Government to spend considerable sums in enlarging existing appliances, and in establishing new laboratories, with a considerable increase of the staff to work them. The tendency of these changes was to increase largely the facilities for study of the physical and experimental sciences, beyond what had been previously considered sufficient for the needs of the Indian services. Of course, there was a difficulty in finding time for the new or ex- tended topics, but this was surmounted eventually, in part by appropriating time occupied by recently abolished studies, partly by diminishing slightly the time devoted to others, but chiefly by making some subjects partially and others wholly alternative. The details and the results may be seen by reference to the college calendars before and after the alteration. For the great advantage of these improvements the college is chiefly indebted to the keen insight of Dr. Siemens, and to his disinterested exertions in pressing on the attention of a justifiably reluctant Government the need for increased expenditure. His far-sighted expectations have, so far, been completely justified; and now, at the beginning of every annual session, the college is crowded with candi- dates for its appointments and diplomas, quite up to the limits of its accommodation. And although some, finding CHAP. VIIL] THE ELECTRICAL THERMOMETER. 331 themselves overmatched, drop off as the session advances, yet the average numbers in residence suffice to bring in a revenue about equal to the large annual expenditure, considerably increased as that has been by the operation of the changes above described. There is good reason to believe that the existing staff of the college, who know the facts, gratefully cherish and revere the name and memory of a man who has done so much for the interests of their institution.* The Electrical Thermometer. He said The invention and progress of Dr. Siemens's Electrical Pyrometer has already been noticed in Chap. VII. In a subsequent paper to the Royal Society, "On a Deep-Sea Electrical Thermometer," read on the 15th of June, 1882, he gave some further particulars of its actual use. it had been largely adopted for determining the temperatures of hot blast and smelting furnaces, and had been found to agree very closely with other measurements between 100° and 1000° Centigrade. It had also been successfully tried for objects where a much greater degree of accuracy was required, as in deep-sea observations. In 1880 he received the following letter from his friend Professor Agassiz, then residing in the United States :— MY DEAR SIR,— MUSEUM OF COMPARATIVE Zoology, CAMBRIDGE, MASS., February 10th, 1880. Referring to a conversation I had the pleasure of holding with you while in London last autumn in regard to your deep-sea * For this sketch of the labours of Dr. Siemens, the author is indebted to his friend, Mr. Calcott Reilly, Professor of Engineering Construction at the college. 332 [CHAP.

I expect to go out in the Blake again next June, to be gone six weeks, and run lines normal to the coast across the Gulf Stream ; and if you feel inclined to send us one of your temperature machines I can only assure you that the officers and myself will do all in our power, not only to give it a fair trial, but to prove it I am very truly, a success. DR. C. W. SIEMENS, London. A. W. AGASSIZ. The instrument was provided and put on board the Blake, and after some delay it was subjected to a series of tests in August, 1881. Observations were taken at various depths, and were compared with the indication of test thermometers, and the correspondence was almost exact. On Dec. 15th, 1881, Professor Agassiz wrote:- You will be glad to hear that the apparatus has worked most satisfactorily; it was carefully tested to 400 fathoms in connexion with Miller-Casella thermometers, under most favourable cir- cumstances, and the general result in a few words is that it is admirable as an instrument of precision, and just what is needed to indicate the crooked lines of temperatures met with in making sections through the Gulf Stream. In 1883 it was applied to the converse use of ascertaining temperatures at great heights in the air. Mr. G. J. Symons, F.R.S., the eminent meteorologist, was desirous of making a record of atmospheric tempera- tures at different levels, and proposed to use for this pur- pose the tower of Boston church, 273 feet high. The first essential was to obtain a thermometer which could be read without climbing to the top of the tower; and this require- ment having been brought to the notice of Dr. Siemens, he suggested the use of his electric instrument, and offered CHAP. VIII.] VIENNA ELECTRIC EXHIBITION. 333 one of them for the purpose. It was placed in a box at the top of the tower, the conducting wires were brought down to the ground level inside the church, and by this means the temperature was read with great ease, concurrently with those on the ground level. The results, which were interesting and important in a meteorological point of view, were communicated by Mr. Symons to the Royal Society on the 6th June, 1883, and are published in their Proceedings. Vienna Electric Exhibition. In 1883, a great Exhibition of Electric Apparatus was held in Vienna. Sir William Siemens was, in July, 1883, appointed by Government to represent this country there, jointly with Lord Sudeley, Sir William Thomson, and Sir Frederick Abel. Towards the end of the month he went over, accompanied by Lady Siemens, and he was busily occupied for about six weeks on the affairs of the Exhibition, to which the London and Berlin firms were large contributors. As an addition to the information afforded by the Exhibition itself, the promoters of it organised a series of lectures, in the theatre of the building, on electrical subjects, and, as a compliment to Sir William Siemens, they arranged that the introductory lecture of the series should be given by him. It was accordingly delivered on the 27th of August, 1883, the subject being "The Relations between Temperature, Light, and Radiation, with remarks on the Sun, and its connection with Electrical Phenomena." The little theatre in the Rotunda was closely filled, as the subject was interesting, not only to electricians, but to the general public. Sir William, before he began his lecture, apologised for 334 [CHAP. VIII. LAST YEARS. addressing the audience in German, as during the last forty years the language of his daily use had been English. He, however, considered it his duty, in addressing a German public, to do so in his original mother-tongue. . In the course of his lecture he stated that the temperature of the sun did not much exceed 2800 degrees Centigrade, being at any rate under 3000 degrees. He thought this might be surpassed by electric furnaces; and that the electric light and heat might be used in many cases to answer the same purposes as those of the sun. The whole lecture was given in a popular style, and though possibly all his auditors may not have thoroughly followed his reasonings, they could at least understand and admire his highly instructive experiments. He made scarcely any mention of his own inventions and discoveries, but he alluded in passing to some of those due to his brother. This brother, the Geh. Regierungsrath Werner Siemens, sat in the pit of the theatre, and apparently much enjoyed hearing a public address from William in the German language. Towards the close of the Exhibition, on the 28th of October, the members of the Academy of Sciences in Vienna made a visit to the Exhibition. They were conducted by the Crown Prince Rudolph, and were joined by Professor Helmholtz, Sir William Thomson, and Sir William Siemens. The Prince conversed with these gentlemen for some time, and expressed his lively satisfaction at being enabled to greet three such learned men in the company of the Austrian representatives of science. Subsequently the members of the Academy took a trip on the Electric Railway, Sir William Siemens directing the train. A few days later, one of the local journals said :- The Electric Exhibition, with the colossal concourse of strangers that it attracted to Vienna, is now over, and we think in the CHAP. VIII.] 335 SCIENTIFIC SOCIETIES. deserted halls of those wonderful machines, driven by that myste- rious power; of the enormous progress that has been made in this comparatively new science; and of the remarkable men whose genius and talent have grasped the mysteries of nature and turned them to the use and benefit of mankind. Perhaps the names most frequently heard during the Exhibition were those of the Brothers Siemens, to whose activity so much electric progress has been due, as their manifold exhibits, lamps, electro-dynamic machines, melting furnaces, electric railways, telegraph appliances, &c., conclusively showed. The greatest proof of their activity is that the firm is become an International one, and has set its foot not only in German, but in English, French, and Russian speaking lands. SCIENTIFIC SOCIETIES.-LECTURES, ADDRESSES. In the last year of his life, Dr. Siemens continued his interest in the various societies he belonged to, confining his attention now rather to the scientific than the practical aspects of their investigations. British Association. In 1882 he was appointed to the proud scientific position of President of the British Association, and opened the proceedings at Southampton on the 23rd of August in the usual manner, with an address, containing, as might be expected, a masterly exposition of the state of science at the time. It had principally reference to the practical applications of science, and it will be found entire among his collected papers. The address was well received, and the popularity of the President was strongly manifested throughout the meeting.

It is usual for a special sermon to be preached before the Association, and at Southampton the duty was taken by Dr. Edward Benson, then Bishop of Truro. Some six months afterwards this divine was made Archbishop of Canterbury, on which Dr. Siemens wrote him the following letter of congratulation :- 3, PALACE HOUSES, KENSINGTON GARDENS, W., 29th March, 1883. MY LORD ARCHBISHOP,- I have only waited for the final assumption by your Grace of the high office which by general acclamation you have been called upon to fill, to recall to your Grace's remembrance the incident when, as President of the British Association, I had the privilege of listening to the broad and enlightened views the members of the Association were treated to at Southampton in August last. May those views be the guiding principles on which the Church of this country will continue to advance, depending on truth in every form rather than upon accepted dogmas for its legitimate influence! Congratulating your Grace on the auspicious event of this day, and earnestly wishing you a long continuance of health and strength for the very responsible duties of that high office, I am, my Lord Archbishop, Your Grace's faithful servant, C. WILLIAM SIEMENS. This letter elicited the following reply :- LAMBETH PALACE, April 1st, 1883. MY DEAR DR. SIEMENS, I thank you heartily for your very kind greeting. It was a great honour to preach before you and the British Association, CHAP. VIII.] 337 THE SOCIETY OF ARTS. and it is too kind of you to remember it. As to the principles themselves of my address, such as it was, they are not only rooted in me, but appear to me to be a part of the very truth of things, so that I earnestly trust in my life's work not to depart from them. The accepted doctrines of the Church, like all accepted dogmas of other kinds of knowledge, however true they are, are never to be withdrawn from re-examination if the occasion arises. They have not failed yet, and every re-examination has, by throwing off disfigurements, brought out the truth more strongly. "Prove all things, hold to that which is good" is Saint Paul's saying, which ought to be written over all knowledge, and which scientific men have in their own region been faithful to. May all be faithful to it in all regions. Sincerely and gratefully yours, EDW. CANTUAR. Society of Arts. The connexion of Dr. Siemens with the Society of Arts has been mentioned in several earlier chapters. He always considered it a suitable institution for the promotion of objects connected with science and industry, and he did all he could to increase its popularity and usefulness. In 1882 he was elected to the office of Chairman of Council (cor- responding with that of President in many other bodies), and he opened the session on the 17th November with an able address. He chose for his subject the capa- bilities and prospects of electric lighting, and he worked out, at much length, a description and estimate of a plan for lighting in this way the whole parish of St. James, containing nearly 30,000 inhabitants, and many public buildings of high order. On the 27th of July, 1883, the Soirée of the Society took place at the International Fisheries Exhibition, South Kensington. It was honoured by the attendance of H.R.H. the Prince of Wales, President of the Society, and the Ꮓ 338 [CHAP. VIII. LAST YEARS. Princess, as well as by many other distinguished persons, either belonging to the Society or specially invited to the fête, the total number of guests being about 6500. Sir William Siemens, as Chairman of the Council, went to considerable trouble and personal expense for this re- ception. The buildings and grounds were brilliantly illuminated by electric lights, installed for the occasion; and many other special arrangements were made for the comfort and pleasure of the visitors. The soirée was a very brilliant one, nothing having been left undone which could tend to make it so. Sir William continued to hold the appointment as chairman of the Council in the following year; the first meeting was fixed for the 21st of November, when it would have been his duty to open the session with another address. On the 8th he took this in hand, and dictated to his secretary a large portion of it, which was immediately set up in type. It contained remarks on electric lighting; on the Vienna Electrical Exhibition; and on Scientific Standards of Measurement. But it was never finished, and on the day when it should have been delivered, alas! the melancholy announcement of his death, two days before, had to be made. Institution of Civil Engineers. At this Institution he joined in many discussions, and in 1883 he gave the official lecture on Electric Power, noticed already. A short time before his death, he received a high compliment from the Institution, namely the award of what is known as the HOWARD Prize. Some years before, Mr. Howard, an eminent engineer and iron manufacturer, had left a bequest to the Institution, "for the purpose of CHAP. VIII.] 339 THE HOWARD PRIZE. presenting periodically a Prize or Medal to the author of a treatise on any of the uses or properties of iron, or to the inventor of some new and valuable process relating thereto." It had been arranged to award the prize every five years, so allowing the fund to accumulate and to increase its value. The first award, in 1877, had been made to Sir Henry Bessemer, and on the prize becoming due again, the Council, on the 6th of November, 1883, passed the follow- ing resolution :— Resolved by Acclamation,―That in consideration of the important discoveries and valuable improvements he has effected in the manufacture of iron and steel, the Howard Quinquennial Prize for 1882 be awarded to Sir William Siemens, F.R.S., Mem. Inst. C.E. This was communicated to Sir William by Mr. Forrest, the secretary, and the acknowledgment of it was one of the last acts of his life. After his death, it was necessary to ask Lady Siemens. to determine in what manner the prize should be given, and she expressed a wish to possess a bronze copy of the celebrated group of "the Mourners," by J. G. Lough, originally placed in the Great Exhibition of 1851, and now in the Crystal Palace. This copy was made by Messrs. Elkington of Birming- ham, who had been Mr. Siemens's first patrons in England, and it bore the inscription, “Howard Quinquen- nial Prize, awarded to Sir William Siemens, F.R.S., Mem. Inst. C.E., by the Institution of Civil Engineers, 1883." It was accordingly presented to Lady Siemens by the Council. It was an appropriate symbol of her sad bereave- ment, and a last affectionate tribute to the memory of their much regretted colleague. Z 2 2 340 [CHAP. VIII. LAST YEARS. French Society of Civil Engineers. In the Autumn of 1881, there was held in Paris a Great Exhibition of Electric Apparatus. At this, of course, the objects exhibited by the Siemens firms occupied a pro- minent position, the electric furnace for melting steel (described more fully at page 313) being a most attractive novelty. Dr. Siemens spent some time there, and was much fêted. During the exhibition, the "Société des Ingénieurs Civils (an institution corresponding to the English "Institution of Civil Engineers") took the opportunity of meeting occasionally in the exhibition building, for the purpose of examining the objects shewn there, and holding technical and scientific discussions upon them. At the first of these meetings, held on the 23rd of September, the members paid Dr. Siemens the compliment of asking him to preside, and to conduct their examinations and discussions. He willingly agreed, and the following procès verbal records what took place. La séance est ouverte à dix heures. M. MARCHÉ (Vice-Président) fait connaître à la Réunion que l'un de nos membres les plus distingués, M. le docteur William Siemens, de Londres, présent à Paris, a bien voulu accepter la Présidence Honoraire de cette première séance. Il ajoute que c'est une bonne fortune pour la Société de faire son entrée à l'Exposition sous le patronage et la direction du savant dont le nom, illustré par lui et les siens, est attaché à tous les progrès réalisés depuis vingt ans en Métallurgie, en Electricité, et en Lumière. M. W. Siemens prend place au fauteuil aux applaudissements de l'auditoire. After the object of the visit and the general programme CHAP. VIII.] THE FRENCH ENGINEERS. 341 had been explained by the Vice-President, Dr. Siemens gave an address in French. He said :- Messieurs, grâce à votre aimable invitation, je me trouve dans ce moment dans une position bien honorable, pour laquelle je vous offre mes remerciments sincères. Cette position m'impose pourtant un devoir, que je me sens peu capable de remplir, attendu que ma connaissance de votre langue est trop limitée et que le temps m'a manqué pour préparer un discours, tel que j'aurais voulu vous l'adresser. Aussi, je compte sur votre indulgence qui, je l'espère, ira même au delà de votre courtoisie. He succeeded, however, in giving them what one of their number afterwards called a brillante allocution on the various uses to which electricity had been put, and concluded by saying:- L'énergie électrique s'applique presque partout, et par elle une nouvelle voie s'ouvre à l'ingénieur pour diriger les forces de la nature, dans un sens qui n'était pas connu auparavant ; j'ai voulu montrer que nous avons devant nous un travail énorme, mais énormément intéressant, à accomplir. After the Exhibition he was gratified by receiving the following letter:- MINISTÈRE DES POSTES ET DES TÉLÉGRAPHES, MONSIEUR LE DOCTEUR,- Cabinet du Ministre, PARIS, le 16 Décembre, 1881. Au moment où l'Exposition d'Electricité vient de se terminer, alors que nous allons publier les glorieux travaux du Congrès, le Président de la République Française a tenu à donner un temoignage de sa gratitude à ceux dont le concours lui semble avoir le plus puissamment contribué au succès de l'Exposition et du Congrès. 342 [CHAP.

J'ai la satisfaction de vous annoncer que, sur mes propositions, mon collègue, M. le Ministre des Affaires Etrangères, Président du Conseil, a fait signer un Décret par lequel vous avez été nommé Officier de l'Ordre National de la Légion d'honneur.

W.), D.C.L., LL.D., F.R.S. à Londres, Membre du Congrès, de la Maison Siemens Frères et Cie. The Birmingham Midland Institute. On the 20th of October, 1881, a newly erected wing of the Birmingham and Midland Institute, in Paradise Street, Birmingham, was formally opened by the Mayor, Alderman Richard Chamberlain, in the presence of a large concourse of the friends and benefactors of the Institution. The proceedings included the usual English feature of a break- fast, and appropriate speeches were made by the Chair- man, by his brother, Mr. Joseph Chamberlain, M.P., and others. In the evening, Dr. Siemens, who had accepted tem- porarily the office of President of the Institution (and who was the guest of Mr. Joseph Chamberlain), delivered a lec- ture which was subsequently published under the title of “Science and Industry," and attracted considerable atten- tion, from the excellent practical character of the views expressed. Addressing himself chiefly to young students, who, as he said, he considered intent on combining science with practical aims, he described the nature of the educa- CHAP. VIII.] THE MIDLAND INSTITUTE. 343 tion best adapted to this purpose, and pointed out its advantages. The lecture was one of the most successful he ever delivered, and was received with great enthusiasm. It was reprinted and widely circulated in pamphlet form, and has been ever since remembered in the town as forming an epoch in its educational history. The following letter was written (in German) to an old friend, the wife of an eminent artist, who had made some comments on the address: HONOURED MRS. HAAG,- SHERWOOD, 22nd January, 1882. I thank you right heartily for your friendly remarks on my Address at the Midland Institute. My object was principally to oppose the present tendency to direct education to specific subjects without thinking that the result must be to produce men of one-sidedness and routine. It has however astonished me that my views have been so generally appreciated and concurred in, showing that my labour has not been entirely lost. I quite agree with you, that a combination of German and English peculiarities should lead to good results, and I do not doubt that your own children, brought up on such excellent principles, will furnish the best proof of this. I am glad to hear that your dear husband keeps well and fresh for his interesting work. Art and Science are mutually necessary for each other, and through their united power will man perhaps come nearer to the God-like type. The lady to whom this was written, adds:- I, like so many others, have lost in him my best friend in England. In him were combined great talents with a noble and unselfish mind. He made his home the rendezvous of all that was great in science, in art, and in literature. He valued persons according to their merits, and had a kind and sympathising word for everybody. 344 [CHAP. VIII. LAST YEARS. In 1882, Dr. Siemens gave £500 to the Industrial Department of the Institute for the purpose of founding an annual prize to the best candidate of the year in Theoretical and Applied Mechanics and Solid Geometry. He said, in writing about it :— It will be requisite to have a design for the medal prepared, and considering that my career commenced in Birmingham with electro-gilding, the medal might perhaps appropriately be a silver one gilt. Prize at King's College. In 1882 he founded also a Prize at King's College, London. The following letter will explain his views in regard thereto :- 14th January, 1882. To the Members of Council of King's College, London. GENTLEMEN, With the object of stimulating the Students at King's College to the acquisition of a high standard of proficiency in metallurgical science, I have thought of offering a premium and medal to be awarded annually upon some such conditions as the following, suggested to me by Professor Huntington :-- 1. That the medal be of gold, of the value of ten guineas, and be known as the Siemens Medal; that the premium be also of the value of ten guineas, to be expended in books or instruments at the option of the medallist. 2. That the course of work extend over three years, the first and second years to be occupied in receiving a grounding in the following subjects:-Higher Mathematics, Physics, Mechanics, Mechanical Drawing, General Chemistry (mainly lectures), Miner- alogy, Geology, Arts of Construction, and Machinery. The third year to be devoted to the special study of Metallurgy. 3. Should there not in any year be any Student qualified to receive the medal, the twenty guineas shall be applied to the purchase of apparatus and books of reference for the Metallurgical Laboratory. CHAP. VIII.] 345 KING'S COLLEGE. On hearing from you that you approve of my proposal, and are prepared to have the necessary examinations made, I shall be happy to place in your hands the funds necessary to have the die of the medal prepared, and subsequently to purchase an annuity or debenture stock producing £21 a year, to be vested in a trust to be appointed by you. It is customary, I believe, that the medal should bear on one side the effigy of the donor; on the reverse side I should propose that there be something typical of Metallurgy. I am, &c., C. W. SIEMENS. It was afterwards settled that the awards were to depend partly on an essay on some particular metallurgical subject, partly on a written examination on the metallurgical lectures, and partly on actual work done in the laboratory. The medal was struck by Messrs. Wyon. It had on one side the head of the donor, with the legend-Car. Gul. Siemens: praemium in arte metallurgica. D.D. 1882. On the other, Dr. Siemens's artistic suggestion was not carried out, but there were engraved simply the arms of the College, with the inscription, Coll. Reg. Lond. Royal Commission on Technical Education. On the 10th March, 1882, Dr. Siemens gave evidence before the Royal Commission on Technical Education, Mr. Bernhard Samuelson in the Chair. In this he made some interesting statements about his own education, which should be quoted entire :- You have received your technical instruction in Germany?—I received all my schooling in Germany. But you have resided nearly forty years in this country?—Yes. In the course of your professional career you have come much 346 [CHAP. VIII. LAST YEARS. into contact with manufacturers and with their foremen and workmen engaged in various branches of industry?—I have. Can you specify some of these branches? I was in early life connected with improvements in steam-engines, and I came therefore in contact with mechanical workmen and their employers. Then I turned my attention to applications of heat, and I came then in contact with iron workers, steel workers, glass workers, enamellers, and a variety of others. Then I have been connected for the last thirty years with electrical engineering, and in that department I have come in contact with workers more as an employer than as one introducing improvements in processes already established. But altogether, I may say that I have come very much in contact with men engaged either as employers, or as foremen, or as workmen, in various branches of industry. Has that experience been confined to this country, or have you had similar experience in other countries ?—I have had a good deal of experience also in Germany, France, and the United States, but not nearly to the same extent as in this country. Perhaps, before we ask you what your experience has been, we might ask you what has been your own education and training?— An irregular one, I may say. I was originally intended for a merchant's office, and I received in early life a general, but limited education. A classical education, or partly classical and partly technical ?— In its early stages partly classical. Then I was sent to a technical school, that is to say, the Gewerbe-Schule of Magdeburg; then, by an act of rebellion, as I may call it, against my guardians,* my parents having died, I went to Göttingen, with scant means, to get a more general education, and I there got a love of science, and a determination to make my own way. Under whom did you study at Göttingen ?—I studied chemistry under Wöhler, geology under Hausman, and physical science under Himly and Listing, who had just come to the university. My mathematical teacher was Stern. Then for a short time I worked in the magnetic observatory of William Weber, but he did * See note on page 26. CHAP. VIII.] 347 LECTURE ON WASTE. not lecture there at that time. I got admission only to assist in the magnetic observations. What age were you then?-Eighteen years of age. Your training was different from the usual training of a German technologist ?—It was. Dr. Siemens's examination before the Commission was very long and full. He was evidently treated as a high authority, and he stated his opinions more in detail, and on a wider range of subjects than in his addresses generally. Lecture on "Waste.” He In October, 1882, he accepted an invitation to distribute the prizes to the Science Classes at Coventry, when he delivered an address with the singular title of "Waste." He had prepared, as he usually did, somewhat complete notes of what he was going to say; but by an accident quite unusual with him, he found, when it was time for him to begin, that he had left these notes at the hotel. would not, however, delay the meeting, but he gave the lecture extempore. It was taken down in shorthand by a reporter, and was published in the Coventry Herald and Free Press, some few extra copies being struck off for him. The lecture has been lost sight of in England, but it was translated and republished in Germany, where its novelty and ingenuity made considerable sensation. It is reprinted in his collected papers. City Guilds. On the 14th December, 1882, he undertook, at the re- quest of the City and Guilds of London Institute, to deliver the prizes and certificates to the pupils at their Technical College, and in his address on that occasion he took the 348 [CHAP. VIII. LAST YEARS. opportunity of remarking generally on the constitution of the Guilds of London, and of comparing it with that of the ancient Guilds of Germany, which he had made himself well acquainted with during his school-time at Lübeck (see Chap. III., page 19). DOMESTIC LIFE. The beginning of the year 1880 found Dr. and Mrs. Siemens in Naples, from which place they made many excursions to the well-known places of interest in the neighbourhood. The museum was a great source of delight to them, and Dr. Siemens had the good fortune to secure a fine vase which had been found shortly before in the region of Ancona, and was supposed to bear a date about 400 years before the Christian era. It now stands in the hall of the house at Sherwood. The love of the beau- tiful was a strong feature in William's character, and the pictures, sculpture, and decoration of his houses gave unequivocal evidence of his taste in matters of art. In February, 1880, Dr. Siemens was elected a foreign member of the Academy of Sciences at Stockholm. On the 4th of August, 1880, Carl Siemens and his family left England to settle again in St. Petersburg. It was a source of deep regret to both Dr. and Mrs. Siemens thus to part from those with whom for eleven years they had lived a happy and united family life. On the 23rd of August, they went to Düsseldorf, where the British Iron and Steel Institute met in this year. A most agreeable time was passed there; every attention and kind hospitality being shewn to all the members. The CHAP. VIII.] 349 DOMESTIC LIFE. fame of the brothers Siemens had reached the place, and at a banquet given in the Town Hall, the healths of Werner and William were drunk with acclamation. On the 18th of September, another great gathering of the Siemens Stift mentioned in Chapter II. (page 16) took place at Goslar, in the Harz. This was remarkable in that all the members interested, sixty-three in number, of "all sorts and conditions" were present, a very unusual occurrence. On October 18th, Dr. Siemens gave a lecture in the schoolroom of Marylebone Presbyterian Church, to the Young Men's Societies' Union, on "the Natural Forces, and their Utilization," with illustrations. No copy of this has been preserved, but it is recollected that the descrip- tions and illustrations were excellently adapted to the inexperienced minds of his auditory. He never grudged either his time or his trouble if he thought he could open a field of interest, on subjects which young intellects could further search out for themselves. In November, 1880, he made an important present to the Oxford University Museum. During the operations attendant on the construction of the Indo-European Telegraph, he had become possessed of a valuable collection of Greek antiquities, including a human skull, and many silver, bronze, and other relics found near Kertch. After keeping them for some years, he resolved to place them where they would be accessible to the public, and he sent them accordingly to the above-named institution. He received a formal acknowledgment, accompanied by the following friendly letter from the curator. 350. [CHAP. VIII. LAST YEARS. UNIVERSITY MUSEUM, Oxford, DEAR DR. SIEMENS,— 20th November, 1880. I have the pleasure of informing you that your gift of a Collection of Greek Antiquities from Kertch has been safely received, and has been most gladly accepted on behalf of the University by the Delegates of the Museum. I enclose the usual formal acknowledgment, but I am requested also to inform you that a special vote of thanks to you for your valuable and munificent present was recorded by the Delegates at their meeting on the 9th instant. Believe me to remain, very faithfully yours, HENRY J. S. SMITH, Keeper of the Museum. C. W. SIEMENS, ESQ., D.C.L., F.R.S., 3, Palace Houses, Kensington. In the spring of 1881, Mrs. Siemens's health being still delicate, Dr. Siemens accompanied her to Cannes, and as the French Scientific Association held their meeting in April of that year at Algiers, he took the opportunity of crossing over from Marseilles to attend it, and his sojourn there interested him much. They returned by Genoa and the Italian Lakes, and crossed the Simplon Pass, which, though just opened for wheel carriages, was still in its winter garb. Soon after his return he received from the Goldsmiths' Company the compliment conveyed in the following letter: GOLDSMITHS' HALL, LONDON, E.C., 19th May, 1881. SIR,- I have the honour to inform you that a Resolution has been passed by the Court of Assistants of the Goldsmiths' Com- pany, granting to you the Freedom and Livery of the Company without payment of the fine and fees. CHAP. VIII.] 351 GOLDSMITHS' COMPANY. I have summoned a Court of Wardens to meet here this afternoon at before 4, when I hope it may be convenient to attend here for the purpose of being admitted. I am, Sir, your obedient servant, WALTER PRIDEAUX, C. W. SIEMENS, ESQ., D.C.L., F.R.S., &c. Clerk. On the 31st May, 1881, he presided at a dinner for the Fund of the Iron, Hardware, and Metal Trades Pension Society. During this address, he gave some particulars of a Pension Fund he had established at his own works; and some large manufacturers present were so struck with this, that they applied to him afterwards to guide them in setting up a similar fund for themselves. In November, 1881, Mrs. Siemens's mother, Mrs. Gordon, who had long been a revered guest in Dr. Siemens's family, died at Sherwood, at the advanced age of 94. A month or two afterwards, an old nurse, also resident on the estate, and who had been for 76 years a loved friend of the Gordon family, also died, aged 96. On June 29th, 1882, Dr. Siemens attended at Dublin to receive the honorary degree of LL.D., which was conferred on him by the University. From there he travelled to Scotland, and Mrs. Siemens, with her sister, met him at Inverness, whence they pro- ceeded together to Dunrobin Castle on a visit to the Duke of Sutherland. It was a great interest to the sisters to shew Dr. Siemens the homes of their ancestors; and, finding the old family burial ground of the Gordons of Carroll in some disorder, he asked leave to repair and decorate it; and he erected a monument, on which, to the satisfaction of the family, his own name was afterwards mentioned as the restorer. 352 [CHAP. VIII. LAST YEARS. In August, 1882, he was called on to give evidence before the Ordnance Select Committee on the manufacture of heavy guns, but no account of the opinions he expressed was made public. After the British Association meeting at Southampton, Dr. and Mrs. Siemens made some pleasant visits in Scotland; a few days at Dunira, with the late Lord Cairns and his family; then at Haddo House, where they were the guests of Lord and Lady Aberdeen; whence they went to their old friends, Sir William and Lady Thomson, at their house near Largs. On the 11th January, 1883, a compliment was paid to Dr. Siemens by the presentation to him of the Freedom and Livery of the Turners' Company. This company, although not one of the rich city bodies, had made them- selves famous by being among the first to revive, in modern times, the encouragement given to the actual practice of the trades they represented. In 1854, the company insti- tuted prizes for the best specimens of turning, in wood, metal, ivory, and other materials; and since 1870, these have been given annually, to the amount of some £140 a year. They have also adopted the practice of electing as hono- rary members of the company, persons distinguished for their skill in mechanics. Previously to this date, the com- pany had so elected Sir William Armstrong, Sir Joseph Whitworth, Sir Henry Bessemer, Sir Frederick Bramwell, Sir John Brown, Sir Charles Hutton Gregory, and others.* Dr. Siemens was elected "in recognition of his eminence as an engineer, his successful application of physical * Among whom the author of this work is proud to find himself included. CHAP. VIII.] 35.3 KNIGHTHOOD. science to valuable practical purposes, especially to electricity and metallurgy, and his personal support of technical educa- tion." Dr. John Percy, the eminent metallurgist, was also awarded the same distinction. A letter was read from Sir Henry Bessemer, in which he stated that "never had the Turners' Company done more honour to themselves than by enrolling among their members two gentlemen who had so highly distinguished themselves in the progress and development of metallurgical science." On the 4th of April, 1883, his sixtieth birth-day, he received the following letter from Mr. Gladstone, then Prime Minister. DEAR SIR,- 10, DOWNING STREET, WHITEHALL, 4th April, 1883. It gives me great pleasure to inform you that I have the permission of Her Majesty to propose that you should receive the honour of Knighthood, in recognition of the service which you have rendered to the cause of science. I hope the proposal may be agreeable to you. I remain, dear sir, faithfully yours, C. W. SIEMENS, ESQ., F.R.S., &c., &c. W. E. GLADSTONE. The actual ceremony is thus described in the Court Circular, dated Osborne, April 21, 1883 :- The Queen held a Council at Osborne yesterday. . . . After the Council the following gentlemen were severally introduced to Her Majesty's presence by the Lord Steward, and received the honour of knighthood, Sir William Harcourt being present as Secretary of State of the Home Department :- Mr. Justice C. B. Butt; Mr. Justice A. L. Smith; Mr. C. William Siemens; Mr. F. A. Abel, C.B.; Mr. Alderman A. Woodiwiss; Mr. Alderman T. Baker; Mr. Richard Henry Wyatt; and Mr. Henry Darvill, A A 354 [CHAP. VIII. LAST YEARS. General the Right Hon. Sir Henry Ponsonby, K.C.B., and Major-General Du Plat were in attendance. H.R.H. Princess Beatrice was present with Her Majesty during the ceremony. The congratulations sent to Sir William and Lady Siemens were legion; expressing not only gratification at the event, but a conviction of the honour being appropriate and well merited. Even Punch celebrated the occasion by a clever fancy sketch, by Linley Sambourne, of Sir William's head, con- tained in the globe of an incandescent electric lamp, and darting out refulgent rays;—the inscription underneath being, "The Electric Knight-Light." On Dr. Siemens obtaining his Knighthood the officials and workmen of the Landore Company determined to present him with an illuminated address of congratulation, and the pretty idea occurred to some one that it might be enclosed in a casket which should be a model of his Regenerative Gas Furnace, as applied to the steel manufacture at Landore. Such a casket was accordingly made; it was an exact model; the parts in brickwork were represented in ivory, and the iron work was made of Siemens steel. The size of it is about 10 inches square and 8 inches high, being one forty-eighth the dimensions of the original furnace. A picture of the Landore Steel Works is engraved on one side, and an allegorical trophy of articles of steel in another place. The upper part is removable, covering a recess for the parchment. The address is as follows:- TO SIR WILLIAM SIEMENS, IL.D., D.C.L., F.R.S., &c., &c. We, the officials and workmen of the Landore Siemens Steel Company, Limited, respectfully avail ourselves of this opportunity CHAP. VIII.] 355 MODEL OF FURNACE. to congratulate you on the honour of Knighthood which Her Most Gracious Majesty has been pleased to confer upon you. We appreciate the fitness of this distinguished recognition of your varied scientific labours, which have contributed so largely to the development of the industrial importance of this kingdom, and hope that you will accept our meed of admiration, which we have embodied in the form of a model of a Siemens's Regenera- tive Steel Melting Furnace, as used at Landore, where by your untiring efforts so many improvements have been effected in your valuable steel-making processes, and being also typical of that section of your work that more intimately connects us with you. We especially feel the appropriateness of the recent mark of Royal favour, from considerations of the important position attained by your invention; the quantity of steel made to the end of last year by your process being upwards of 4,000,000 tons. We also tender this to you as a sincere expression of our high esteem, regard, and gratitude, hoping that Divine Providence may long spare you to continue to benefit the various departments of human knowledge and industry, which your genius has already so much enriched. We have the pleasure and honour to subscribe ourselves, on behalf of the employés. (Here follow fifteen signatures of the Chief Officials of the Works.) LANDORE SIEMENS STEEL WORKS, 1883. The model took some months to make, being so full of small details; but, when it was finished, it was arranged that the presentation should be made at a public dinner to be given to Sir William Siemens at Landore Works, on the 17th of November, 1883, and the invitations were issued accordingly. About a week before the day, the presentation was post- poned; and it never took place. The model was after- A A 2 356 [CHAP. VIII.

The following is an extract of a letter written shortly afterwards to Sir William Thomson :- ; 29th June, 1883. A sad blow has come upon us all through the death of Spottiswoode. Few men combined so many noble qualities and filled their places more worthily. Personally I have lost in him a very esteemed and kind friend. I was the first, I believe, to call the attention of the Dean of Westminster to his great claims to national recognition, and steps have been taken to give his remains a resting-place in Westminster Abbey. Mr. Spottiswoode was buried in the Abbey on the 5th of July. ILLNESS AND DEATH. We now approach the last sad scene of this busy life. The removal of Sir William from the sphere of his labour was very sudden and unexpected. Some of his most intimate friends had noticed for a little time that he had a depressed look, which could not be accounted for by any worldly care or anxiety; but there was no suspicion of any derangement of health requiring medical advice, and there was no relaxation of his ordinary work. On the contrary, he was exerting himself more than usual. Shortly after he had given his lecture at the Vienna Electric Exhibition, he was obliged to return to England to be present at the meeting of the British CHAP. VIII.] 357 LAST ILLNESS. Association at Southport, where, on the 19th of September, he had to resign his Presidency, and introduce his successor, Professor Cayley. After this he travelled to Ireland to meet the Lord Lieutenant at Port Rush on the 28th of September, for the opening of the Electric Railway. He went from Glasgow to Belfast, and a very rough crossing of the Irish Sea, acting on a frame fatigued by incessant occupation and hard travelling for many days, brought on unpleasant sensations of giddiness, which he had experienced be- fore when over-worked. But the success of the railway opening and the congratulations of his friends inspirited him, and in a few days he returned home apparently well again. He paid a few visits with his wife in England, and then left again to resume his duties at the Vienna Exhibition, remaining there till it closed, and returning on the Ist of November. He still showed no serious ailment; but there can be little doubt now that the unusually hard work of the last few months had undermined his strength. Instead of getting, as he was wont to do, an autumn holiday, to recruit his mental and bodily powers, he had exerted both body and mind much more than usual. There had been appointed for Monday, the 5th of November, a meeting of the Council of the Society of Arts, and as Chairman he should, if possible, have attended. But in the early part of the day he caused the following letter to be sent to the Secretary :- DEAR SIR,- : 5th November, 1883. Sir William Siemens instructs me to say that he regrets he shall not be able to attend the Council Meeting of the Society 358 [CHAP. VIII. LAST YEARS. of Arts to-day; he has an important matter to bring before the managers of the Royal Institution, whose first meeting takes. place to-day at the same hour as your own. I am, &c., E. F. BAMBER. Walking home from this meeting about five o'clock in the afternoon with his friend Sir Frederick Bramwell, he was crossing the opening of Hamilton Place on the north side of Piccadilly, when, not noticing in time the kerbstone of the pavement, he fell heavily with his left arm under him. He felt no serious hurt and walked on home; taking no notice of the fall except to laugh at it. For three days afterwards, he was at his place of busi- ness as usual, and on one of these days he wrote a letter to Sir William Thomson, saying nothing of illness, but full of plans for the immediate future, chiefly as to the realization at Sherwood of his latest ideas in the production of heat without smoke. On Thursday, the 8th, the last day he was at his office, he spent the whole morning in dictating to his secre- tary, Mr. Bamber, a large portion of the address which he was to give on the 21st November, as Chairman of the Council of the Society of Arts. But on attempting to walk home as usual, he found the exertion almost too much for him, from pain and breathlessness, and he was obliged to sit down and rest in the Park several times. On Friday, the 9th, he remained at home; but he was still not incapacitated for work, for he gave attention to a matter which, though of little real importance, caused him some annoyance. It had reference to the manage- ment of the steel works at Landore. The previous day he had received the following letter from a friend at Bradford, Yorkshire :- CHAP. VIII.] 359 SUNDAY LABOUR. November 7th, 1883. DEAR SIR,- We had a discussion this week on the opening of Museums and Free Lectures on Sundays, and among other things your name was introduced. It was stated that at your works at Swansea the men had struck work against Sunday labour, and after being out eleven weeks had gone in again (that is, had accepted Sunday labour as before). Also that you were a Vice- Chairman or Member of the Sunday Society. Would you mind giving me all information possible on this question ? I may say I am in favour of opening them on Sundays, and should feel obliged if you would give me the information. Excuse me troubling you. Yours truly. Sir William Siemens answered this as follows:- 9th November, 1883. DEAR SIR,- I have pleasure to reply to your inquiries regarding my views on Sunday labour and Sunday spending. I have the greatest possible objection to Sunday labour, and if your informant were to visit the Landore Steel Works he would be satisfied that Sunday labour is reduced to the least possible amount, and that a foreman engineer was discharged very lately because he persisted in Sunday work, on account of the extra wages. The steel-melting furnaces and the blast furnaces of the works cannot be put out, however, during Sunday without entailing such heavy losses that the whole works would come to a standstill, and it was only a pretence on the part of some of the workmen last year, to raise an objection against such indispensable Sunday work in order to cover other demands. The men had, indeed, been excited by professional agitators, and are at present well satisfied. Regarding the Sunday Society, I think that what they demand would prove beneficial to the working classes and be consistent 360 [CHAP. VIII. LAST YEARS. with religious feeling. I therefore allowed my name to stand as a supporter of the movement, although I have not taken an active part in their proceedings. I am, yours truly, WILLIAM SIEMENS. In the early morning of Saturday, the 10th, he awoke with an acute pain in the region of the heart, and with coldness in the lower limbs. Medical aid was sent for, and the remedies that were applied, hot baths and friction, removed the pain. There was also some congestion of the left lung, but this passed temporarily away, and Sir William spent two or three days in the drawing-room. Indeed, so much better did he seem, that it was arranged he should go to his country seat at Sherwood, where it was hoped he would be able to get that complete rest which was thought necessary for his recovery. On Monday, the 12th, he acknowledged the award to him of the Howard prize by the Institution of Civil Engineers, as mentioned on page 339. In the meantime, some explanation had been received from his Bradford correspondent, and on the 14th he dictated and signed the following further communica- tion 3, PALACE HOUSES, KENSINGTON GARDENS, W., 14th November, 1883. DEAR SIR,- I am in receipt of your further communication regard- ing the statement which appears to have been made in your town about myself, upon apparently the most meagre possible information. * * * * * It may interest you to learn that some hundreds of the work- men at the Landore Steel Works have invited me, their Chairman, CHAP. VIII.] 361 LAST ILLNESS. • to a public dinner, which was fixed for the 17th inst., to present me, I believe, with a handsome model of the very steel furnace that will not be put out like a kitchen fire every Sunday, while on the other hand it gives daily bread to about 2000 families of the neighbourhood. A slight accident makes it unfortunately impossible for me to attend on the 17th, and the banquet has to be put off till the Ist of December. It will be attended, I am informed, by the M.P.'s and other leading men of the district, and will give me an excellent opportunity of pleading my own cause before the parties said to be aggrieved, who will be my hosts; and before gentlemen of cultivated understanding. I am glad to learn that you personally approve of Sunday lectures, which I am only sorry that press of other engagements prevents me from giving the heart-felt support that they deserve. The enclosed card will enable you to judge more clearly the character of the intended festival. Yours faithfully, WILLIAM SIEMENS.* This was his last business effort. On the same day he appears to have taken a chill, which affected his lungs, for on that night he was attacked by a difficulty of breath- ing; and although not actually confined to his bed, he never left his room again. Still, however, no fatal result was feared, for on the afternoon of the 19th, two medical men had consulted together, and had spoken hopefully of him. He remained for four hours after this in a calm state; but about nine o'clock in the evening, as he was sitting in his arm-chair, a change was observed suddenly to come over him, and peacefully and quietly, as if he were falling asleep, his spirit passed away. * This correspondence was published in the Bradford Observer of 20th December, 1883. 362 [CHAP. VIII. LAST YEARS. A post-mortem examination was made, and it was then found that there had been a serious disease of the heart of long standing, and that its influence had been aggra- vated by a slight rupture due to the fall. He could not have lived long, and it was a matter of wonder that the disease had not affected his general health at an earlier time.

The influential officers of the two institutions with which he was most nearly connected, namely, the Institution of Civil Engineers and the Society of Arts, took the initiative in this matter, and on Wednesday morning, the 21st of November, the following letter was written to the Dean of Westminster :- THE INSTITUTION OF CIVIL ENGINEERS, 25, GT. GEORGE Street, S.W., 21st November, 1883. The Very Reverend the DEAN OF WESTMINSTER. REVEREND SIR,- I am desired by the Council of this Institution to bring under your notice the loss which the world has sustained by the death of Sir William Siemens. His exceptionally great abilities had won for him universal distinction. His attainments in many branches of Science and its applications were so various that he had occupied the positions of President of the British Association, of the Institution of Mechanical Engineers, of the Iron and Steel Institute, and of the Society of Telegraph Engineers. For many years he had belonged to this Institution, of the Council of which he was a member. Honoured by Foreign Sovereigns, by Foreign Academies, by the Universities of this Country, he also lately received a special mark of Royal favour as a recognition of his great merits. Under these circumstances, the Council venture to express the earnest hope that you, Reverend Sir, may see fit to allow his remains to rest in the venerable Abbey under your charge. I have the honour to be, Reverend Sir, Your most obedient humble servant, JAMES BRUNLEES, Fresident. In the afternoon of the same day the following reply was received :— 366 [CHAP. IX. “ANERKENNUNG.” SIR,- DEANERY, WESTMINSTER, S.W., November 21st, 1883. I much regret that, owing to my being engaged this afternoon at two important meetings, some delay has occurred in my receiving and answering the memorial which lies before me. I may, however, say at once that the question to which it refers had been anxiously considered before any direct communication had reached me. As regards the claims of the late lamented Sir William Siemens to national recognition, on the ground alike of his scientific attainments and his important services to the comfort and welfare of mankind there can, I imagine, be no doubt. So far, however, as regards the special mode of honouring his memory by his interment in the Abbey, I feel myself, with great regret, unable to accede to the wish expressed in the memorial. Recent investigations have compelled me to realize to myself the exceedingly restricted space that is left at the disposal, for this purpose, of the present and future guardians of the Abbey. It is absolutely necessary that interments within its walls should take place only on the rarest occasions, and in, so far as human judg ment can be trusted, absolutely exceptional cases. I am expressing no opinion as to other modes of honouring the memory of one whose striking claims to distinction have, as the memorial before me points out, been, I rejoice to see, so widely and gratefully recognized in his lifetime. Believe me to remain, very faithfully yours, THE PRESIDENT OF THE INSTITUTION OF CIVIL ENGINEERS. G. G. BRADLEY. The Dean further stated, in oral communications, that in making arrangements for the funeral of Mr. Spottiswoode (the President of the Royal Society, who had been buried in the Abbey on the 5th of July) he was deeply impressed with the extremely restricted space now available, and it was obvious to him that it must be jealously guarded for the future. CHAP. IX.] 367 THE FUNERAL. He, however, expressed himself ready to meet the wishes. of the applicants as far as possible, and he let it be under- stood that he was not unwilling to consider the question of erecting a bust, or other memorial in the Church, or even of holding the principal part of the funeral service there, if any such proposal should meet with influential support, particularly by persons independent of the engineering profession. Emboldened by this concession, the Institutions decided to make a formal request for a public recognition of Sir William's great achievements in Science by a funeral service in Westminster Abbey, and they presented it on Thursday, supported by the following letter:- To the Very Reverend the DEAN OF WESTMINSTER. REVEREND SIR,— We, the undersigned, earnestly desire to support a memorial which we understand has been presented to you by the Council of the Institution of Civil Engineers and other public bodies, urging the claims for the funeral service of the late Sir William Siemens being held in Westminster Abbey. This received in one day the signatures of a large number of distinguished persons. At their head was His Royal Highness the Prince of Wales, and following him were the Marquis of Hartington, Viscount Cranbrook, Lord Bram- well, Lord Alfred Churchill, Sir Rutherford Alcock, Sir John Lubbock, the President and other officers of the Royal Society, Sir Joseph Hooker, Sir Frederick Leighton, Pro- fessor Richard Owen, the Astronomer Royal, Archdeacon Farrar, and many other well-known names. The Dean was perfectly satisfied with this support, and he acceded to the prayer of the memorial. The burial took place on Monday, the 26th of November. 368 [CHAP. IX. "ANERKENNUNG.” The relatives and friends of the deceased and of Lady Siemens met at the residence in Palace Houses, from whence the coffin was borne on an open funeral car to Westminster Abbey, accompanied by the principal relations on both sides, and by a few intimate friends. Meanwhile, distinguished public personages and repre- sentatives of scientific bodies were assembling in the Jerusalem Chamber or in the Abbey, members of societies not attending in official capacities having places assigned them in the sacrarium or transepts, and the choir and seats under the tower being reserved for Presidents, Vice- Presidents, Members of Council, and officers of the Societies invited to be present. The ancient tapestried chamber which had been the scene of many such sad gatherings, was filled-indeed crowded-with the many warm friends whom the genial nature of the man had won to him, not only among men of his own profession, but among those whose pursuits were widely different, The Prince of Wales was represented by one of his grooms-in-waiting, Mr. Andrew Cockerill; the German Ambassador, Count Münster, was there, and others who came were the Chancellor of the Exchequer, Mr. Childers; the First Commissioner of Works, Mr. Shaw Lefevre; Lord Bramwell; Lord Claud Hamilton; Mr. F. R. Pickersgill, Keeper to the Royal Academy, representing the President, Sir F. Leighton; Sir Theodore Martin, and other distinguished individuals. Taking the scientific societies and their representatives in the order in which they were marshalled to join the procession, there were, as pall-bearers, Professor Huxley, President of the Royal Society; Sir Frederick Bramwell, predecessor of Sir William Siemens in the office of Chairman of Council of the Society of Arts; Mr. (now Sir James) Brunlees, President of the Institution of Civil Engi- CHAP. IX.] 369 THE FUNERAL. neers; Mr. Percy Westmacott, President of the Institution of Mechanical Engineers; Professor Sir William Thomson, for the British Association; Professor Tyndall, for the Royal Institution; Mr. Willoughby Smith, President of the Society of Telegraph Engineers and Electricians; and Sir James Ramsden, representing the Iron and Steel Institute. These societies were also represented by other office- bearers and members of council, among whom were some of the most distinguished men of science and engineers of the day. There were also officially present represen- tatives of the Royal Astronomical Society, the Royal Institution of British Architects, the Chemical Society, the Royal Meteorological Society, the Institution of Naval Architects, the Society of Engineers, the Geological Society, the Society of Chemical Industry, the Physical Society, and the German Athenæum. Forming a long procession, the occupants of the Jerusalem Chamber filed past the Westminster School-room, and meeting the family mourners at the entrance from Dean's Yard, took their appointed places, and followed the coffin through the Cloister to the Canon's door in the south side of the Abbey. As the body was borne into the building the choristers began to chant the opening sentences of the Burial Service, singing as they walked, and leading the way up the centre of the nave into the choir. The clergy present were the Dean, Archdeacon Farrar, Canon Prothero, Canon Duckworth, Canon Rowsell, the Rev. Flood Jones, Precentor, and the Rev. J. H. Cheadle and the Rev. E. Price, minor canons. The gold-fringed black and white pall was thrown back over one end of the coffin, that the more beautiful cover- ing of flowers might not be disturbed. Many of these loving gifts had come from distant places. The Earl and B B 370 [CHAP. IX. “ANERKENNUNG.” Countess of Aberdeen sent a wreath; one of palm branches came from the establishment of Messrs. Siemens and Halske at Berlin; others from those at Woolwich and at Westminster, and there were some from nearly every country in Europe. The Anthem was one composed by Dr. J. F. Bridge for the funeral of Mr. Darwin, to the following words :- "Happy is the man that findeth wisdom and getteth understanding. "She is more precious than rubies, and all the things thou canst desire are not to be compared unto her. 66 Length of days is in her right hand, and in her left hand riches and honour. "Her ways are ways of pleasantness, and all her paths are peace." After the lesson, which was read by the Dean, a hymn (No. 401, Hymns Ancient and Modern"), beginning, "Now the labourer's task is o'er," was sung, and the Benediction having been pronounced by the Dean, the coffin was carried out of the Abbey through the north aisle door, the organ playing the "Dead March in Saul." It seemed as if the greater part of the large assemblage must have joined the procession to the cemetery at Kensal Green, for at no point in the route could the whole length of the string of carriages be seen. The chief employés at Westminster and Woolwich followed, as well as a deputation from Berlin. At the cemetery there were also present many of the workmen from the telegraph factory. The grave was formed beside one in which the mother of Lady Siemens had been laid to rest a few years before. Its head was encircled by a bank of grass and flowers breast high, and its sides were hidden by flowers and fern fronds. The committal sentences and prayers were read by the Rev. H. R. Haweis. CHAP. IX.] 371 THE FUNERAL. The inscription on the coffin was simply- C. WILLIAM SIEMENS, DIED 19TH NOVEMBER, 1883, AGED 60 YEARS. It was a pathetic and yet a noble ending to the scene, when his brother Werner, who had been his elder play- mate in childhood, his faithful guardian in youth, and his true and loving friend all his life through, turned away sadly from the grave, and exclaimed to a relation walking with him:- Nun das ist vollendet! Ein so volles Leben! ein so schöner Tod! und eine solche ANERKENNUNG! Ich könnte ihn beneiden! The word "Anerkennung," here so emphatically used, furnishes an appropriate title for this final chapter; sum- ming up, as it does, the testimony spontaneously offered to Sir William Siemens's character and merits, and the public appreciation of the benefits he had conferred on the world. A simple monument was subsequently erected over the grave, on which was sculptured an admirable medallion portrait of Sir William, by Mr. Bruce Joy. MEMORIAL WINDOW. The other suggestion of the Dean of Westminster, namely, that a bust or other memorial might be erected in the Abbey, was not forgotten. The Institution of Civil Engineers again took the lead. The Council believed it would be possible to obtain the concurrence of the other kindred societies in the promotion of an "Engineers' Memorial" to Sir William BB 2 372 [CHAP. IX. “ ANERKENNUNG.” Siemens; and, as a preliminary step, they applied to the Dean, asking if it would be agreeable to the authorities of the Abbey that a Memorial Window should be erected therein. Having obtained a reply in the affirmative, the councils, past presidents, and officers of the following societies, namely:-The Institution of Civil Engineers; The In- stitution of Mechanical Engineers; The Institution of Naval Architects; the Iron and Steel Institute; and the Society of Telegraph Engineers and Electricians, were invited to attend a meeting "to consider what steps should be taken to promote an Engineers' Memorial to the late Sir William Siemens." The meeting was held on the 28th of June, 1884, the President of the Institution of Civil Engineers in the chair; when it was resolved that such a memorial should be erected, and that the subscription (confined to the members of the Societies named) should be limited to one guinea each. The estimated cost was from £700 to £800, and a committee was formed to collect subscriptions, and to carry out the proposal. The committee entered into communication with the architect of the Abbey, Mr. J. Pearson, R.A., and with the artists, Messrs. Clayton and Bell, who, after the designs had been settled, and had been approved by the Dean, were commissioned to execute the work. It was completed and fixed in November, 1885. It was arranged that the ceremony of unveiling the window should take place at 2 o'clock on the 26th of November, being the second anniversary of the funeral. The subscribers and other friends invited assembled in the Jerusalem Chamber, where they were met by the Abbey authorities. There were present several relations CHAP. IX.] 373 MEMORIAL WINDOW. and friends of Sir William and Lady Siemens, and many representatives of the societies who had combined in the undertaking, with Sir Frederick Bramwell, F.R.S., President of the Institution of Civil Engineers, at their head. The proceedings were opened by the Dean, who said: Sir Frederick Bramwell, and all who are here to-day, either as the representatives of a great profession or as the relatives and friends of him whose memory we have met to honour ;—we may, I think, well dispense with any formal handing over on your part to the custodians of this venerable building of the memorial which you have raised to your illustrious friend. You will at all events permit me, in their name, gratefully to accept it. You will allow me also to give a cordial welcome to those who at so exciting a time have come here to inaugurate its enrolment among the number of those monuments which recall, to successive gene- rations of Christian worshippers and visitors from all lands, the names of men who have rendered signal services to their fellow- men. No pains have been spared to make that memorial worthy, alike in conception and execution, of the spot in which it has been placed and of him whose name it will recall-recall, I trust, to far-distant ages, for I cannot believe that Englishmen of any party or any school will allow those walls to moulder or that roof to fall. It is not for me to dwell for a moment on the signal services to the cause, not only of science, but still more the application of science to the well-being of mankind that will be always associated with the name of Sir W. Siemens. Nor need I say one word of the gap, still keenly felt, which his death has left in your ranks. Even the weighty words of your president-weighty they must be are not needed to make you feel deeply on such a subject. But I may add my own personal testimony to the impression which the character of your friend and leader, for such in a wide range of subjects I may surely call him, made on all who came into contact with him. He was, as you know and as I know, not only admired and honoured, he was beloved and deplored. May the window, which we shall now uncover, do its proper 374 [CHAP. IX. “ ANERKENNUNG.” work. May it not exclude but admit through storied glass the chastened light of our too often sombre skies—a light whose subtle and marvellous play on our walls and arches and arcades and pillars and monuments sometimes touches, with an indefinable power like that of music, the hearts of those who daily meet here to worship One who has revealed himself to man in divers ways and sundry measures, not least of all in the great realm of nature, in the laws of light and all its kindred forces. And may it remind us and far-off generations of the achievements and the character of him whose memory will henceforth be here linked with that of his illustrious brethren, whose names the floor on which we shall soon stand and the walls beneath which we shall pass proclaim and preserve the Newton, the Herschel, and the Darwin, the Stephenson, the Locke, and the Brunel, the Barry, to which add the Gilbert Scott, and Street—who sleep or are honoured hard by. I have detained you long enough, and you will, I am sure, wish me to ask for a few words from Sir F. Bramwell. Sir F. Bramwell then spoke as follows :- Mr. Dean, Dr. Werner Siemens, Miss Gordon, and other relatives and private friends of the late Sir William Siemens. In the first place, Mr. Dean, we have to thank you for the kindly terms with which you have welcomed us. This kindness is in continuation of that which two years ago accorded to the late Sir William Siemens a public funeral service in this Abbey. We have met here to-day for the purpose of unveiling the window which has been placed in the north aisle by certain of the members of the five engineering institutions or societies with which Sir William Siemens was connected. Of the Civil Engi- neers he was for many years a member of the council; of the Mechanical Engineers a past president; of the Naval Architects a member of the council; of the Iron and Steel Institute a past president; and of the Telegraph Engineers he was not only a past president, but he was also one of the founders. It must not be supposed that his connexion with these institutions was one of mere title, or in any sense of a perfunctory character. The positions that he filled in them would be sufficient to disprove CHAP. IX. x.] 375 ÉLOGE. this; but the fact is that there is not one of them but was enriched by his communications, and was benefited by his presence at its meetings, and by his remarks at those meetings upon the com- munications of others. It was the members of these societies who felt that they might fairly claim for themselves the privilege of placing here this token of their respect for the man who had done so much for engineering science as a whole, and for each of these societies in particular. It would, we must all agree, be unseemly if we were to allow the memorial window to be unveiled without a statement, however brief, of some of the qualifications which earned for Sir William Siemens the high position he attained. Leaving out of considera- tion for the moment questions of pure science, it is only the truth to say-truth unexaggerated by friendship and by the promptings of regret that great as has been the development and progress of engineering in this nineteenth century, no man contributed more than the late Sir William Siemens to that development and progress by the application of science to engineering and to the industrial pursuits allied therewith. His very first visit to this country was in connexion with an application of electric science, and I think I am right in saying that so long as that science exists and its records are preserved, the name of William Siemens will be honoured as the author of important applications of electricity in connexion with submarine and other telegraphy; with lighting, and to some extent with the transmission of power; and also to some extent with the utilization of electrical energy for the fusion, on a commercial scale, of refractory materials, while the employment of electric light as an adjunct to that of the sun to stimulate vegetable growth must ever remain an interesting contribution to science. No man had more at heart the obtaining proper value from the store of fuel that Providence has laid up for us, and no one studied, more ardently and more successfully than did Sir William Siemens, the means whereby heat-motors should give results more nearly approaching to the limit of that which is theoretically obtainable than was given by the motors then in use. The annals of the Institution of Civil Engineers and those of the Mechanical Engineers are replete with his instructions; and, following up this subject of economy of fuel, we owe to Sir • 376 [CHAP. IX. "ANERKENNUNG.” William Siemens the development in this country of those beau- tiful inventions whereby, in many industrial and metallurgical pursuits, fuel is saved and temperatures are attained, and attained under a perfect state of control, admitting of novel processes being pursued, such as, to take a typical example, the hearth process of steel manufacture. In matters of pure science we owe to Sir William Siemens not merely the knowledge of the effect of continuous light upon the growth of plants, to which I have already alluded, but we owe many philosophical modes of measurement. It was a hardy con- ception which devised the bathometer, by the aid of which, and without taking soundings, the depth of the ocean could be ascer- tained by the mere reading off of the indications given by the instrument on board ship. Again, profound must have been the thought that produced the electrical pyrometer, which, while competent to deal with ordinary temperatures, was also suited for ascertaining the highest temperatures, and the readings, electrically transmitted, could be taken at any distance without the removal of the instrument from the place the temperature of which was being ascertained. I know there are those who regret that Sir William Siemens did not confine the employment of his remarkable talents to the pursuit of pure science, but I do not think that this regret is justified even in the interests of pure science itself, and I am sure it is a regret that will not be shared in by mankind at large. They, I believe, will agree that Sir William Siemens was doing not only good but noble and high work when he used his talents and devoted his scientific knowledge to the application of that science to engineering and to industrial pursuits; and even purely scientific men should rejoice that from time to time there are found those who, like Sir William Siemens, make practically useful for the purposes of life those truths which science has discovered, but which, failing application, would remain inert and barren of useful consequences; a condition of things which, if it continuously prevailed, would inevitably cause all interest in science to cease, resulting in the abandonment of the pursuit of pure science itself. It would be wrong to close these remarks without a reference to those qualities which in the highest degree inspire our respect CHAP. IX.] 377 MEMORIAL WINDOW. -I mean his worth as a man. If modesty, kindliness, benevo- lence, and truthfulness constitute a good man, then one may unhesitatingly say that Sir William Siemens was, in the full sense of the word, a good man; and those qualities met with their recognition and their reward, even in this world, by the unbounded confidence which was reposed in his honour. I have not hitherto alluded to the fact, so well known to us all, that Sir William Siemens was not by origin an Englishman. He was a member of the great German race, born in Hanover, but he came first among us when he had not attained his majority, and after a few years settled in England, and then became naturalised as an Englishman. I am glad to think that from his first appearance here he was well received, and as years went on, and his mar- vellous talents and most estimable qualities became more and more known, the respect and the admiration that were felt for him in- creased; and it is a deep satisfaction to us to know that in this Abbey, a building venerated not only in the country of his adoption, but in that of every English-speaking race, a building, the subject of interest to the whole civilised world, we, his brother engineers, have the privilege of placing that which I trust shall be a memorial for ages to come of that able and good man who, two years ago, was taken from us, but whose work will live in industrial and in scientific records, and whose memory will live in the hearts of all those by whom he was so justly respected and beloved. One last word I have to say, and no one is better entitled to say it than I am, that happy was the man who secured his friendship, for that friendship never wavered and never waxed cold. The Dean then thanked Sir F. Bramwell for his address, and a procession was formed to witness the unveiling of the window, which is situated on the north side of the nave, next to the window which commemorates another great engineer, Robert Stephenson. The ceremony con- cluded with the recital of a few prayers by the Dean.* * These accounts of the ceremonies in Westminster Abbey are taken from reports in the Times. 378 [CHAP. IX. “ANERKENNUNG.” The general outline of the window is shown on the accompanying Plate, and the following is the description of it given by the designers :—- The design in this window is to set forth the sanctity of Labour, illustrating the maxim "Laborare est orare.” The treatment of the work comprises a series of groups repre- senting, respectively, workers in Science, Art, and Manual Labour. The window consists of two lights with a sixfoil in its traceried head. Each of these lights is composed of three panels in vertical order. In the left-hand light appear Ironsmiths, Chemists, and Agriculturists; in the other, groups in corre- sponding positions show Astronomers, Artists, and the Professor with his scholars. Between these groups are in all cases Angels bearing labels inscribed with the words giving the key-note of the conception, viz., "Laborare est orare. In the sixfoil, at the head of the window, is a representation of the Sun as the source of light, surrounded by the words "Dixit autem Deus fiant luminaria in firmamento cœli," and by the various heavenly bodies from which light emanates or is reflected. This passage of the design has special reference to the researches of the eminent genius to whom the memorial is dedicated, and whose portrait occurs in the figure of the Professor with his pupils in the lower group in the right-hand light. At the base is the following inscription :- IN MEMORY OF CHARLES WILLIAM SIEMENS, KNT., D.C.L., LL.D., F.R.S., CIVIL ENGINEER, BORN 4 APRIL, 1823: DIED 19 NOVEMBER, 1883. ERECTED AS A TRIBUTE OF RESPECT BY HIS BROTHER ENGINEERS. The artistic treatment of the work may be described as generally in harmony with the architectural style of the Abbey. On the other hand, its entire freedom from close antiquarianism recon- ciles its effect with the significance of the subject-matter and the spirit of the times.

The arrangements for the two ceremonies at the Abbey were made, in conjunction with the Abbey authorities, and Sir William's representatives, by the Institution of Civil Engineers, through Mr. James Forrest, their secretary. Sir William Siemens's will was proved on the 29th December, 1883. It was dated on August 21st, 1882. The executors were Mr. Alexander Siemens, Mr. Joseph G. Gordon, and Mr. J. W. Budd, and the value of the personal estate was sworn a little over £380,000. He left no children. OBITUARY NOTICES. The eloquent éloge pronounced by Sir Frederick Bram- well on his friend's memory may be appropriately followed by a notice of the wide-spread manifestations of regret that were called forth by his death, and which furnished unequi- vocal proof of the general estimation in which he was held. The various societies to which Sir William belonged, hastened to record their grief at his loss, and to commu- nicate sympathetic addresses to Lady Siemens. The Institution of Civil Engineers, meeting the day after his death, passed this resolution: That this meeting desires to record the deep sense of the loss the Institution has sustained by the decease of their eminent and highly esteemed colleague, Sir William Siemens, and their sincere sympathy with Lady Siemens in her irreparable bereavement. The Institution of Mechanical Engineers and the Society of Telegraph Engineers passed resolutions to a similar effect. The Royal Institution put on record, at their meeting on the 3rd of December, the following resolution : In the death of Sir William Siemens the Royal Institution has 380 [CHAP. IX. “ANERKENNUNG.” lost an eminent member and a generous friend. The outcome of his great practical researches was frequently brought before us in lectures delivered in our theatre; he was our benefactor in pre- senting to us apparatus of great value; while his wise counsel, as a manager, was ever ready when the interests of the Institution required it. He showed his veneration for one of its Professors by naming a vessel-a model one of its kind-constructed under his personal supervision for the transport and laying down of telegraph cables, "The Faraday." In everything he touched, practical genius, gifted by a knowledge of principles not frequent among practical men, was displayed. In the domains of heat, electricity, and metallurgy, he won his chief renown, and here the ultimate issues of his labour are at present incalculable. England, the land of his adoption, has lost through his death an engineer of singular power, penetration, and many-sidedness. The source of the quality last mentioned, by which he was cha- racterised, was, first of all, inherent ability, and secondly, the com- prehensive scientific education which he received in the seminaries and universities of his native land. He came to us thoroughly equipped with the theoretic knowledge necessary for practical ends, and he applied that knowledge successfully to the most varied spheres of action. As regards invention, he came of a family to the manner born; all his brothers, and especially his eldest brother, the celebrated Dr. Werner Siemens, having achieved distinction in applying sciences to the uses of life. William Siemens was a man of the most charming disposition, genial, kindly, without jealousy or bitterness, and as a natural result he secured not only the respect but the warm affection of those who intimately knew him. The members who were present on the occasion of our last monthly meeting will not readily forget the animated description he then gave us from the chair of a new application of steam power which he had just seen tried on the River Spree near Berlin. How little could the freshness and the vigour of that exposition prepare his hearers for the catastrophe so soon to follow! Among the members of the Royal Institution he has left many mourning friends, who profoundly sympathize with his family in their great bereavement, and more especially with Lady Siemens in her irreparable loss. CHAP. IX.] 381 OBITUARY NOTICES. At a Council Meeting of the Society of Arts, held on the 26th November, the following resolution was passed: The Council of the Society of Arts desire to record their sense of the very heavy loss which the Society has sustained by the sudden death of their Chairman, Sir William Siemens. Pre-eminent among those who have successfully devoted them- selves to the advancement of knowledge, it was his peculiar merit to have applied the results of scientific research to industrial progress, and to the improvement of many of the conditions of human life. From the versatility of his genius and from the direction of his more important labours, he was singularly well fitted to lead the work of a society which, devoted to many and various objects, has for its special provision the application of science to practical purposes. The Society which thirty-three years ago honoured itself by the award of its gold medal in recognition of talents not then evident to the world, now mourns the loss of one who was long closely associated with its work, and who for some time back took an important share in the administration of its affairs. His talents were the admiration of his contemporaries, but his rare personal merits could be known to those only who were fortunate enough to share his friendship. The facility with which he applied his powers to the solutions of the most difficult scientific problems, was equalled by the modesty with which he presented the successful results of his efforts. While thus recording their sense of their loss, the Council desire further to express their deep sympathy with Lady Siemens and with Sir William Siemens's distinguished brothers, Werner, Carl, and Friedrich, who were so closely associated with his labours. This resolution was transmitted to Lady Siemens by His Royal Highness the Prince of Wales, as President of the Society, and was accompanied by the following letter: 382 [CHAP. IX. “ANERKENNUNG.” MADAM, December 27th, 1883. As President of the Society of Arts, I have to com- municate to you a Resolution adopted by the Council of that Society at their last meeting, expressing at once the sincerity of their regret at the loss of their distinguished Chairman of Council, and their sympathy with yourself. In doing this, you will permit me to add the assurance of my own sympathy, and of my appreciation of the loss which the country has sustained by the sudden death of Sir William Siemens. I am, Madam, Your obedient Servant, ALBERT EDWARD, P., President of the Society. Some weeks afterwards, Lady Siemens sent a photograph of Sir William to the Prince of Wales, who caused to be transmitted to her the following gracious reply: MY DEAR MADAM,— SANDRINGHAM, Norfolk, 30th December, 1883. I have not failed to place your letter and the photograph which accompanied it, in the hands of the Prince of Wales. I am desired to return you his sincere thanks for them, and to assure you that it gives him very great pleasure to possess the photograph of one whom he so highly respected and esteemed. His Royal Highness considers the likeness a very good one, and he much appreciates your having sent it to him. Believe me, my dear Madam, Yours very truly, FRANCIS KNOLLYS. But the most striking testimony to Sir William Siemens's merits and character was furnished by the obituary notices that appeared in the public press-remarkable both from their great number and their earnest character. CHAP. IX.] 383 PRESS NOTICES. The extent of the manifestation was very wide. In the first place, there was an original obituary notice in every London daily journal, both morning and evening, in most cases of considerable length, and sometimes accompanied by a special leader. This, of itself, was sufficient to mark the occurrence as one of much public interest. Then followed the London weekly or bi-weekly journals; in above fifty of which notices were seen. It mattered no- thing whether they were exclusive or popular, were learned or simple, were general or intended for special readers. All alike, whether such as the Athenæum, or the Academy, or the Spectator, or the Figaro, or the Guardian, or the Record, or the Graphic, or Truth, or the Court Circular, or the Satur- day Review, or the Queen, or the Lancet, or the Builder, or Nature, or the Broad Arrow, or Land and Water, or the City Press, or the Penny Illustrated Newspaper, all had words of praise for his life, and regret for his decease. Then of country papers, there were a legion. Extracts were noted in some sixty or seventy, but these were certainly only a portion. Every paper in every town had its notice, and Sir William's name seemed familiar to the whole kingdom. Such notices were not confined to England. The German press teemed with complimentary obituaries; in Paris alone paragraphs were inserted in sixteen journals; in Brussels, St. Petersburg, and Vienna, his name ap- peared; and in smaller and remoter places, such as Rouen, Bordeaux, Riga, and Algiers, and even in the western hemi- sphere the readers of the journals were supposed to know who was meant by Sir William Siemens. Some of the notices were written with great ability, and showed much acquaintance with the subjects dealt with.* * Among these may be specially cited those in the Times, written by fellow-officers with him in the Society of Arts; in Engineering, 384 [CHAP. IX. “ANERKENNUNG.” In the best articles the admiration expressed was discrimi- nating and explicit, and far removed from the stereotyped forms of laudation so often used. A few extracts will serve to show the general nature of the press appreciation of Sir William's character and labours. Times. The death of Sir William Siemens, at the comparatively early age of 61, deprives the world of the services of a singularly powerful and fertile mind. His remarkable career was dis- tinguished not less by unfailing goodness and generosity than by intellectual activity. It will be admitted by all that if we are to have a national Pantheon, none can more justly claim a place therein than a man who has attained the highest eminence in the subjects which it is the boast of the present day to have carried to a perfection unknown before. Sir William Siemens was essentially an inventor. In whatever direction he turned, his thoughts seemed to perceive new methods of working out old problems, or to discover new problems which it immediately became his business to solve. The inventor proper is one who, like Sir William Siemens, is continually throwing out original ideas in spheres where others find it sufficiently difficult to master what has already been done. By his death English science has suffered a severe loss, and a loss which will not readily be made good. At a time when the tendency of science is more and more to specialise itself, and scientific men are often compelled to study one particular branch of a subject alone, it is very rare to find a mind like that of Sir William Siemens, who devoted himself to many distinct branches of science, and yet excelled in them all. Not only has he done much for the advancement of pure science, but it may be said without contra- written by his private secretary; and in Nature, contributed by his most intimate scientific friend, Sir William Thomson. There was also an excellent account of his metallurgical labours in the Engineer, and a work lately published, "The Creators of the Age of Steel," by W. T. Jeans (London, 1884), contains a memoir that deserves honourable mention. CHAP. IX.] 385 PRESS NOTICES. diction that he has, beyond all his contemporaries, promoted the practical application of scientific discoveries to industrial pur- poses. He was an ardent scientific discoverer, a large and successful manufacturer in at least two different branches of industry, an engineer of high rank in the profession, and besides this, he was a shrewd and clear-headed man of business. Those who knew him may mourn the kindly heart, the generous noble nature, so tolerant of imperfect knowledge, so impatient only at charlatanism and dishonesty. The nation at large has lost a faithful servant, chief among those who live only to better the life of their fellow men by subduing the forces of nature to their use. Looking back along the line of England's scientific worthies, there are few who have served the people better than this her adopted son; few, if any, whose life's record will show so long a list of useful labours. His lot was in many ways enviable, for he escaped, as very few have, the shafts of envy; and to the end of his active and useful career he was esteemed and honoured by his competitors and by those who knew him best. Standard. The sudden death of Sir William Siemens is an irreparable loss to industrial science in every quarter of the world where the fame of his inventions has reached. Daily News. The death of Sir William Siemens leaves a large gap in the ranks of applied science, as well as among the most distinguished of England's adopted citizens, Morning Post. It is interesting to compare a life like that of Sir William Siemens with those of equally great and earnest workers in other fields of labour. There probably are people who would give Darwin a higher rank as a scientific investigator and inventor than they would accord to Siemens. Yet there cannot be much doubt сс 386 [CHAP. IX. "ANERKENNUNG.” which of the two conferred the most substantial benefits on the world. All Sir William Siemens's discoveries had the direct and immediate effect of stimulating the national industry in one department or another, and thus making the country stronger and richer. Pall Mall Gazette. A veteran in the great war against waste, which is one of the most distinctive marks of modern civilisation, passed away when Sir William Siemens met his sudden and untimely end. Globe. The premature death of Sir William Siemens calls attention to a career that may be safely called unique in the annals of science. Saturday Review. There is a legitimate reason for satisfaction at the practical absorption into English life of such a man as Sir William Siemens. We do not know whether he would have called himself an Englishman or a German; it is certain that few Englishmen thought of him as the latter. Nations less liberal in the theory, or less successful in the practice of adopting foreigners, some- times reproach us with our hybridity, which, in truth, is a silly reproach. When a country has such an absence of national life or character that it is obliged to import its great men, it is in a bad way enough. But when it has such an abundance of character and of life that it attracts men of genius and capacity and absorbs them, it is certainly not in a bad way at all. Hardly any country has such a faculty of absorption of this kind as England, and in none perhaps is the process more thorough. In Sir William Siemens's addresses and speeches, which were not few, there was a welcome lack of the aggressive and arrogant tone sometimes charged, and not always unjustly, against men eminent in the more practical branches of physical science. This was—it may be in part, at least- owing to the thorough education which it has been said he had received. CHAP. IX.] 387 PRESS NOTICES. Spectator. The work of Sir William Siemens deserves notice, not only because of the interest which attaches to great achievements, but also because his career bears witness at every step to the practical value of scientific generalisations. Engineering. A great man has passed away from us with startling suddenness; a great man in the sense in which Watt and Faraday were great; a man who has left an indelible impress upon the science and industry of his age and of the future. Although not actually the inventor of a new industry like Bessemer, or the discoverer of some all-important law of nature like Faraday, the extensive application of his furnace and pro- cesses must give him high rank amongst engineers. If he has passed away prematurely, he died with honours thick upon him; at least, he had not to wait for tardy recognition of those grand abilities and that indomitable perseverance which long since placed him in the van of the profession. The Engineer. His remarkable ability had made him a leader of thought and progress in so many branches of science, and of science applied in arts and manufactures, that his name is familiar to people in every walk of life, and every one will experience the feeling that a great and unexpected loss has taken place in the ranks of the modern leaders of men and makers of great industries. Science loses by his death one of its most remarkable thinkers. In him was found that most unusual combination, originality guided by accurate and diverse knowledge, and backed by executive ability and untiring energy. Nature. The death of Sir Wm. Siemens, coming as it did so suddenly and unexpectedly, has been felt as a severe blow and grief through a far wider circle than that of his personal friends. His work for CC 2 388 [CHAP. IX. "ANERKENNUNG.” the last five or six years has interested the general public in a degree that has perhaps never before been the lot of any man devoted to science as he has been. Not only the people of his adopted country, England, but the larger public of the whole civilized world have been deeply interested in his works and inventions, in which they have recognized him as an originator and devoted worker and a friend. His death is mourned as an irreparable loss, and the thought that advances in so many lines of beneficent progress, carried on by his untiring activity and his splendid zeal, are so suddenly stopped, has caused most grievous dis- appointment. William Siemens had the great characteristic common to all men who have left their marks on the world, the perfervidum ingenium, in which thought leads to instant action. Electrician. He was the representative, probably the ablest representative, of what may be called the modern school of scientists, who strive to unite the practical and the theoretical sides of science into one consistent whole. In his own person he was eminently fitted to represent this union. Several of the Societies he belonged to published, in their transactions, special obituary notices of him, each giving usually an epitome of his career, and having special rela- tion to his connexion with the particular society. Among them may be particularized those of the Royal Society, communicated by Sir William Thomson; of the Institution of Civil Engineers, written by the Honorary Secretary, and of the Society of Telegraph Engineers, by Mr. Munro. The life, works, and character of Sir William Siemens have also been dwelt upon in many lectures and addresses, both in England and abroad. Some of these have been published, and a few may be noticed here. A formal éloge was delivered before the French “ Société CHAP. IX] 389 ADDRESSES. “ d'Encouragement pour l'industrie Nationale," by M. Mar- cart, and is published in their proceedings. It commenced thus: Sir W. Siemens, que la Société d'Encouragement comptait parmi ses correspondants, est un des hommes qui ont le plus contribué aux recents progrès de l'Industrie. Ses nombreux inventions, qui ont, en général, pour caractère d'être la traduction pratique des principes les plus délicats de la science, lui donnaient une au- torité légitime, et l'opinion publique, en Angleterre, ne crut pas exagérer l'estime qu'elle avait pour lui en plaçant son nom à côté de ceux d'hommes de génie tels que Watt et Faraday. At the meeting of the British Association in Montreal, September, 1884, Lord Rayleigh, the President, in his opening address, said:- Now, again, a well-known form is missing. For many years Sir W. Siemens has been a regular attendant at our meetings, and to few, indeed, have they been more indebted for success. Whatever the occasion, in his Presidential address of two years ago, or in communications to the Physical and Mechanical Sections, he had always new and interesting ideas, put forward in language which a child could understand, so great a master was he of the art of lucid statement in his adopted tongue. Practice with science was his motto. Deeply engaged in industry, and conversant all his life with engineering occupations, his opinion was never that of a mere theorist. On the other hand, he abhorred rule of thumb, striving always to master scientific principles which underlie rational design and invention. It is no exaggeration to say that the life of such a man as Siemens is spent in the public service; the advantages which he reaps for himself being as nothing in comparison with those which he confers upon the community at large. The President, also, of the Mechanical Section, Sir Frederick Bramwell, alluded feelingly to the loss the Association had sustained. He said:- I had, indeed, thought of making his work the subject of my 390 [CHAP. IX. “ANERKENNUNG.” address; but I felt that his loss was so recent that I could not trust myself to attempt it. There is no need for me to dwell further upon this most painful topic. He was known to you all, he was honoured and loved by you all, and by every member of the Association he had so faithfully served, and over which he had so ably presided. On the Sunday after his death, the Rev. J. E. Manning, M.A., preached a sermon at Swansea in honour of his memory, the audience being largely composed of persons connected with Landore. This came singularly apropos a week or two after a public speaker at the other end of the kingdom had been charging Sir William with making himself unpopular at Swansea by insisting unnecessarily on Sunday labour ! At the beginning of 1884 the Verein zur Beförderung des Gewerbfleisses, in Berlin, to which Sir William had for some years belonged, published in their Quarto Proceedings a lecture given to the Society by Professor H. Wedding. It began as follows:- On the 19th November we lost our Honorary Member, whom we Germans have called Herr Wilhelm Siemens, and the English Sir William Siemens. This double popular name expresses the salient character of this man, who united the German scientific learning with the British practical activity in such happy wise, that both nations were equally proud of him. And looking to the statements of his merits which have been given by the most dis- tinguished men on both shores of the German Ocean, we may imagine only a single regret to be felt reciprocally by both nations; the Germans lament that such a man did not devote his whole life to his fatherland; the English, on the other hand, regret that he was not a Briton born.. On the 22nd February, 1884, a lecture in German, on "Sir William Siemens als Erfinder und Forscher" (as inventor and investigator), was given by Dr. Eugen Obach, CHAP. IX.] 391 LECTURES. to the "German Athenæum," a society of Germans in London, of which Sir William had long been a member. He had always a particular regard for it; had often attended its meetings, and given them addresses; and they took a prominent part in his funeral. Dr. Obach's lecture was much admired by the members, and was pub- lished at their request. (C On the 18th January, 1885, one of the lectures of the Sunday Lecture Society" was given at St. George's Hall, Langham Place, by Mr. William Lant Carpenter, B.A. It was on "The Life and Work of Sir William Siemens." Mr. Carpenter had been an intimate friend of Sir William for many years, and had established a School of Electrical Engineering, in Hanover Square; he was, therefore, in a position to estimate Sir William's life and work at their proper value. After giving an excellent illustrated description of his chief works and principal inventions, the lecturer quoted, at some length, opinions and statements he had collected from various sources, illustrating his personal character. One or two extracts from the lecture may be given. Of his character as a man of business let Messrs. Chance speak, as one testimony out of many. "Our firm having been the first to carry out in England on a large scale the Siemens regenerative process, we were brought into close and frequent communication with him, and had the opportunity of appreciating not only his extraordinary inventive powers, but also his thorough straightfor- wardness and integrity of character." The German Athenæum wrote :-" If the world of science has lost one of its brightest stars, the poor, the striving student, as well as the struggling artist, have lost a liberal benefactor and a patron." A noble, beautiful, and gifted spirit has passed to the higher and fuller life, and with us is left an influence for good which cannot die. Just as this generation is now profiting by the solar 392 [CHAP. IX. “ ANERKENNUNG.” radiation which fell on the earth countless ages ago, so will the labours of Charles William Siemens form a store of knowledge, potential with respect to this and succeeding generations, and destined to confer advantages, greater than we can now estimate, on the ever-advancing cause of science, and on the moral, intel- lectual, and material progress of humanity!* And, speaking of lectures and addresses, it is worth mentioning that a German periodical of considerable note, the Patent Anwalt of Frankfort-on-the-Maine, published a proposition that in all high schools throughout Germany, during the course of half a year, lectures should be given on Sir William Siemens's Life and Work, as an incentive to young students to follow in his steps. SPECIAL CHARACTERISTICS. The above notices will suffice to show the estimation in which Sir William Siemens was held by the scientific world, by his professional brethren, and by the public at large. It only remains now to add a few words as to traits in his character more definitely observed by those who knew him intimately. As a man of science his high position was admitted on all hands. Without any affectation of abstruse learning, he had a thorough knowledge of the theoretical principles of the natural sciences with which he had to do, and he was thus able to deal with them in practice, not empirically or tentatively, but on a firm basis of sound logical reason- ing, which guided him unerringly in their applications. He was mathematician enough to work out the many difficult * This lecture is published in the Gentleman's Magazine of March, 1885. CHAP. IX.] SPECIAL CHARACTERISTICS. 393 problems required in his work, and in physics and chemistry he was an acknowledged master. The Royal Society obituary notice says:-" His work in the domain of pure science has been neither slight nor unimportant, because, in experimentally developing his inventions, his mind was ever on the alert; and hence his efforts towards the practical application of the results of science, in many cases, served to put these results in a clearer light." As an engineer, it is enough to say that if the province of the engineer is "to apply the great powers in nature to the use and convenience of man," there have been very few men in the profession who could show a higher claim to the title. He was probably one of the best and most accomplished mechanics that ever lived; and when any important engineering task of unusual nature or magnitude was presented to him, such, for example, as the design of the "Faraday,” his thorough knowledge of the principles of construction and the properties of materials, combined with his ready inventive power, made its solution easy to him. It is impossible to read his mechanical essays, or his multifarious remarks on all sorts of subjects, at the meet- ings of the engineering societies he attended, without admiration of his remarkable ability in the profession he had attached himself to. Of his character as an inventor much has already been said, but the inventions which have been described or alluded to in this memoir have necessarily only been those of the most saiient character and of the greatest importance in their results; they form only a small portion of the immense inventive labour of his life. He was one of the most prolific and versatile originators of novel combinations 394 [CHAP. IX. “ANERKENNUNG.” that the mechanical world has ever known, as is proved by the number of inventions patented in England to which his name is attached. Many of these are taken out jointly by himself and some of his brothers, but it may be fairly assumed that his own part in most of them was real and important. The patents are 113 in number, and they range over an enormous field of subjects, including steam engines, hot-air engines, gas-engines, water engines, cooling and freezing, evaporation and distillation, river engineering, the iron and steel manufacture and other branches of metallurgy, gunnery, measuring apparatus, pneumatic tubes, glass making, armour plating, tele- graphs, electric lighting, electric power, and electric ap- paratus generally in great variety, gas lighting, railway appurtenances, explosive compounds, and other miscel- laneous matters. But even this list, lengthy as it is, is far from being a complete register of his inventions, seeing that there were great numbers of minor novelties con- tinually springing from his fertile brain, which were either merged in the processes of manufacture, or were described to the world without protection, or indeed may have had only an ephemeral object, and have been forgotten alto- gether. And in order to judge of the full weight of the long list, it must be recollected that his patents were not, as is so often the case, the crude ideas of an uneducated schemer, but that, although many of the inventions have not been carried out, the known capability of the inventor is a pretty good guarantee for their being sound in principle and feasible in practice. In addition to this list he had many more inventions in prospect, on some of which he was actually experimenting in his last days. As a man of business his character was exemplary, nothing was neglected that he had to do, nothing post- CHAP. IX.] SPECIAL CHARACTERISTICS. 395 poned that could be done promptly. His habits of work have been thus described by one who was in daily com- munication with him :- "What a labourer he was a glance at his daily occupations will show. His secretary was with him at nine o'clock nearly every working day of the year; there was work for one society or another to be done, proofs of the abstracts of the Institution of Civil Engineers to be examined, letters and opinions on scientific subjects to be dictated, frequently also specifications of new in- ventions already schemed out. Then followed the walk across the Parks, almost at racing speed, to Westminster; the business of the Landore Siemens Steel Company, of Messrs. Siemens Brothers and Co. (of both which large undertakings he was chair- man), the work in connexion with the furnaces and metallurgical operations of which he was the inventor; visitors and enquirers to be seen, and in the afternoon attendance at council meetings of the learned societies, or directors' meetings of various companies. The evenings, again, were spent at one or other of the learned societies. This gives a faint idea only of the way Sir William Siemens passed his weeks and months and years. When a man has to address himself within the space of an hour to subjects so different as those for instance of telegraphy and metallurgy in their scientific aspects; when he has to consider workmen and wages one moment, licenses and specifications of inventions the next; when, as was constantly the case, half-a-dozen people were waiting at the same time to see him, each thinking his own busi- ness the most important, and to each of whom Sir William gave his attention, the wonder is that he has been able to work so long." His business position, combining with the legitimate profession of a civil engineer the occupations of a manu- facturer and contractor on a very large scale, was some- what unusual, but the way in which this came about has been already alluded to. He saw with great acuteness at an early period of his life that, in a line of practice com- paratively new, and likely to have a very large extension, 396 [CHAP. IX. “ANERKENNUNG." his devotion to manufacture would open a much wider and more lucrative field for his powers than mere designing and, supported in this view by his brothers, he embarked in it accordingly. And again, at a later period, when engaged in the study and perfecting of his great heating and metallurgical inventions, he found it would be out of the question to attempt to get the necessary preliminary trials, on a large and expensive scale, carried out in the trade; indeed, apart from the risk which deterred the manufacturers, he experienced a determined opposition by the uneducated and prejudiced workmen which alone would have crushed a less energetic and persevering man. And he accordingly embarked, for the sake of these metallurgical inventions, in the actual extensive manufactures they re- ferred to. These undertakings were not free from the risks which so often attend large commercial speculations in a new field, and in some instances they caused much anxiety, and not a little pecuniary sacrifice, to himself and his friends. But his energy and perseverance carried him through all difficulties, and in his later years it may be said that everything he did was successful in all points of view. He had the discrimination to surround himself in his busi- ness transactions with able coadjutors and assistants, whose aid he was always glad to acknowledge. It is nothing against him to say that in his strictly business transactions he usually kept his own pecuniary interests well in view. In his very earliest negociations, we find him in Hamburg, calling himself a "simpleton that he did not get eight louis more," and in Birmingham asking Mr. Elkington in the first instance “much too high a price." A couple of years afterwards, he valued his two nearly abortive inventions at the modest sum of £86,000. These were youthful fancies; but the same spirit, sobered down, animated him through all his business life. CHAP. IX.] SPECIAL CHARACTERISTICS. 397 In 1873, he alluded pointedly (see page 400) to his efforts in the pursuit of his own interests, and it was well known to all his clients, that, when his services were required in a professional or commercial way, he did not hesitate to put a sufficient money value upon them. If, as some- times happened, the price he asked could not be paid, he preferred to do the work gratuitously, rather than accept what he considered insufficient remuneration. The amount at which his will was proved may perhaps. be considered some evidence of this trait of character; but the figure there given does not represent nearly the money he earned, seeing the heavy losses that at different times he had to sustain, the liberal gifts he made, and the large sums that he spent in other ways. It was said by one of his friends, that he had made three fortunes; of which he lost one, spent one, and kept one. But his desire to become rich must always be associated with the considerations that he gained his wealth grace- fully, and that he put it to honourable and creditable uses. No instance has come to the knowledge of the writer of this biography where any charge has been brought against him of illiberality in his business dealings. He insisted that his clients should pay him properly, but he also took care that they should get full value for their money. Then when we come to inquire what he did with his wealth, we find everything to his credit. He valued it, not for itself, for he had no inclination to hoard it; not as a means of vain display, for he had acquired fame enough in other ways; but he valued it for what it would usefully do. It would enable him to cultivate freely his tastes for scientific investigation; to gratify his natural instincts of generosity and liberality; to do something for art; and to enjoy the refined social and domestic pleasures con- genial to his habits, his tastes, and his education. 398 [CHAP. IX. “ ANERKENNUNG.” In regard to one of these uses of money, namely, generosity and liberality, it is difficult to say here all that might be said without an appearance of laudatory exaggeration. During his whole life he was proverbially generous to those who had any sort of claim to his aid; and in his later years, he extended his liberality to a much wider range. Not only personal gifts, but subscriptions almost without end, to charitable objects, as well as large prizes and presents to Educational and other Institutions, figured in the columns of his cash account. He was once appealed to to join in a guarantee fund, to purchase a very large amount of valuable specimens for the Government museums, which would otherwise have been lost, taking the risk of being repaid by the Treasury at a future time. He at once put his name down for £1000, and took the position of "Provisional Manager in the transaction. His offer of £10,000 towards a "Hall of Applied Science" has already been mentioned. " He gave his residences the air of comfort and even luxury, but it was not the luxury of mere ostentation. He decorated his houses with the best taste, and he filled his rooms and his corridors with pictures, sculpture, and other beautiful works of art, mostly commissioned from well-known artists whom he numbered among his friends. His entertainments, too, though sometimes magnificent, had always the laudable object of bringing together those whose presence would make the banquet a "feast of reason," and not a mere animal gratification. He had one qualification which is not very common among hard mechanical workers, i.e., considerable literary power, of which he took full advantage. It was not his wish or his habit to confine to himself the knowledge he had gained; he was ever ready and anxious to communi- CHAP. IX.] SPECIAL CHARACTERISTICS. 399 cate it to the world. He was an admirably clear writer, and, although a foreigner born, he acquired a knowledge of English, and an ability of using it, very remarkable, as is shown by the many excellent papers he contributed to the scientific societies in this country, and the many other able documents that came from his pen. He was also a good lecturer, and his command of English was almost as perfect in speaking as in writing. The author of this memoir has frequently had occasion to notice, when hearing him speak without any preparation, that, although he had not alto- gether what might be called a fluent delivery, his choice of words and mode of expression were such as could hardly be improved. He would sometimes hesitate a moment, as if at a loss for a word, but the word he chose was always the right one. Many of his speeches and addresses have not been. preserved. It is seldom that one can get, for the biography of a practical man, a clear statement of his own estimate of his character and powers; and it is still less often that such an estimate may be looked upon as true and trust- worthy. It happened, however, that in 1873 he was asked, as were many other eminent men, by Mr. Francis Galton, so well known for his scientific statistical researches, to give such a statement, and by the kind permission of Mr. Galton, (which he gave subject to the sanction of Lady Siemens), it may be reproduced here. Dr. Siemens's description of himself was as follows:- Height, 5 ft. 10½ in. Ordinary figure. Red hair. Fair com- plexion. Has actively pursued Physical Science in addition to his pro- fession. Religion liberal Protestantism. : 400 [CHAP. IX. "ANERKENNUNG.” Politics Liberal. : Good constitution. Active habit; restless disposition; easily fatigued, but perse- vering and naturally adventurous. Quick-minded and capable of sustained efforts in the pursuit of his interests. Bad memory for names and dates, but moderately good as regards facts or circumstances. Principles in physical science are clearly retained. Not naturally studious, but receptive and imaginative. Independent in judgment in social, religious, and political matters. Naturally diffident, but sanguine and determined to accomplish objects of importance. Passionate but soft-hearted. His special talents, he considers, are for mechanisms and phy- sical principles. Facility to conclude amicable arrangements in business, and to carry them through in a conciliatory spirit.* His strongly marked peculiarities he describes as irresistible desire to realise objects in applied science when once conceived, which objects have sometimes been pitched too high, and have led to fruitless expenditure of means and energy, although the principles have been proved. Attained considerable success in other cases. Domestic habits, with love of the new, but not of the marvellous. This description will probably be cordially endorsed by his most intimate friends; and it certainly was fully cor- roborated by the outward and visible signs appreciable by the world. The letter accompanying the statement gives one or two indications of character not alluded to therein. I should not be acting according to my natural character if I had prepared the enclosed returns for you one day sooner than * This remark, considering its date, must probably have been suggested by his great success with the difficult and complicated Indo-European telegraph negotiations. CHAP. IX.] 401 SPECIAL CHARACTERISTICS. absolutely necessary to avoid your displeasure. Few people know themselves, so I do not pretend to have drawn a correct picture of myself; but at any rate I have answered the questions to the best of my conviction. At a subsequent date Mr. Galton put some further ques- tions to him as to his power of "visualizing," that is, of calling up, in his mind, pictures of objects or scenes which he had had to do with, or which he was otherwise earnestly cogitating upon. Mr. Galton says:- He told me that he visualized with clear definition of Form, and in Colour, and that he had no difficulty in mentally perceiving the successive phases of motion in complicated machinery. Also that in thinking out a machine, he did it best while walking; better than when sitting at a table with a pen in his hand. Comparing what he told me with what others had said or written, I classed his visualizing power as exceptionally high. His characteristic of intensity in whatever he did was remarkable. Even in his relaxations he entered into them with his whole heart; indeed, it did one good to hear his ringing laugh when witnessing some amusing play, the face lit up with well-nigh child-like pleasure; and there was no trace of the weariness which perhaps, an hour before, had been so visible after a long day of work of such varied kinds, all demanding his most serious atten- tion. As a travelling companion he was indeed the light and happiness of those who had the privilege to be with him. Everything that could lessen fatigue or add to the enjoy- ment and interest of the journey was thought of and tenderly carried out; and the knowledge of the pleasure he was giving was his best reward. Young people and children clustered round him, and he spared no trouble to answer simply and clearly any ques- tions they asked him. D D 402 [CHAP. IX “ ANERKENNUNG.” Of his general character in private life, so far as it was observable by those outside his family, nothing can be said but unqualified praise. The impression produced on those who knew him personally cannot be better expressed than in the words of one of his dearest friends. "In private life Sir William Siemens, with his lively, bright intelligence always present, and eager to give pleasure and benefit to those around him, was a most loveable man, singularly un- selfish and full of kind thought and care for others. The writer has for nearly a quarter of a century had the happi- ness of personal friendship with him. The occasions of meeting him are among the happiest of recollections. The thought that they can now live only in memory is too full of grief to find expression in words." CAMPA INDEX. ADAMSON. ADAMSON, Joseph, makes improve- ments in water-meters, 107.

"In the two handsome and beautifully printed volumes before us one of the greatest of America's historians has proved that the epistolary Muse of English literature dare not give her Transatlantic sister odds. There is a portrait of Mr. Motley in the first of these volumes, and the book accurately fulfils the promise of his captivating countenance. A better example of the trust that may be placed in the good looks which have been described as better than any other letters of introduction is not often met with. Our sole object in this notice is to make it clear to all whom it concerns that Mr. Motley's correspondence is a boon to book- lovers, and is as well worth purchasing as it is beyond all question well worth reading. In a word, this correspondence may be not untruly said to be a most valuable addition to a most pleasant department of literature, and as such it deserves all the success which we most con- fidently anticipate for it."-Spectator. 2 Mr. Murray's List of New Publications.

THE DUKE DUKE OF WELLINGTON'S • CONVERSATIONS WITH THE LATE EARL STANHOPE. 1831-1851. Fourth Edition. Crown 8vo. 75. 6d. The literature and history of England already owe much to the house of Stanhope, and these 'Conversations' will considerably increase the debt-an extremely interesting little volume. All classes of readers may find their account in this book; chatter or scandal about the living there is not, but there is almost everything else. Those who gauge a book solely by the number of amusing stories it contains will find plenty to their taste, and yet more is there to the taste of those who are interested in improving their acquaintance with one of the greatest captains who has ever made war; one of the finest characters in human story; the bravest, truest, most unselfish, and most unswerving man who has ever served his country at any time in any capacity."-World. "The volume is a museum of anecdote, history, and opinion, abounding so much in good things that it is difficult to select, and almost impossible to abridge."-Spectator. 4 The whole volume is replete with reminiscences of the Great Duke of the most interesting description."--Morning Post.

Here we see displayed his tenderness of heart, his love of children, his strong sense of humour, his fund of anecdote, his independence of speech, his fervent piety, his loyalty to his friends and to his University. No student of religious life in this country during the XIXth Century can afford to neglect so rich a collection of anecdotes, and no Oxonian should pass by a work which is inspired by a passionate enthusiasm for much of what is best and noblest in the past or present life of Oxford."—Athenæum.

"Mr. Guillemard has done well in publishing a cheaper edition of that admirable book of travel The Cruise of the Marchesa, in which he showed to so much advantage both as a nar- rator of his various experiences on his different voyages, and as a keen observer of the natural history of the strange lands which he visited during the cruise.

With Portrait. 2 Vols. 2 Vols. 8vo. 36s. · "Mr. Fitzpatrick, while presenting to us a collection of moderate extent, has not only woven them into a web of fair average continuity, but has, as a sculptor would, presented to us his hero in the round,' so that we may consider each of his qualities in each varied light, and judge of their combination into a whole, whether it is mean or noble, consistent or inconsistent, natural or forced. Few indeed, as I think, of those who give a careful perusal to these pages, will withhold their assent from the double assertion that he (O'Connell) was a great man, and that he was a good man. Upon this issue the volume now before us will enable us to try him; and in trying him to try ourselves. For who can any longer doubt that some debt is still due to him; that he was, to say the least, both over-censured and under-valued?"-Mr. GLADSTONE, in The Nineteenth Century. " THE CAREER OF MAJOR GEORGE BROADFOOT, C.B., IN AFGHANISTAN AND THE PUNJAB. COMPILED FROM HIS PAPERS AND THOSE OF LORDS ELLENBOROUGH AND HARDINGE. By MAJOR WM. BROADFOOT, R.E. With Portrait and Maps. 8vo. 15s. An officer of rare capacity-killed in the prime of life. How high was the estimate of George Broadfoot may be gathered not only from his deeds, but from the eulogies of friends who were competent judges. Colin Mackenzie inscribed on his grave these words, 'The fore- most man in India,'-and, added Havelock, ' truly in intellect and resolution he was. The same noble soldier, speaking of the siege of Jellalabad, called him 'greater than any or all that fought in defence of that old wall, and spoke of his 'more than Roman self-devotion,' his tenderness of heart and 'uncompromising love of truth.' Sir Henry Lawrence said 'he had no equal on the frontier, and perhaps few in India;' while Lord Hardinge wrote, -' He united a greater variety of admirable qualities than any other officer I have met with in the Indian Army.' Herbert Edwardes, commenting on the Battle of Firozshah, refers to him as ⚫ foremost among the dead as he was ever foremost among the living.""-Spectator. 4 8 Mr. Murray's List of New Publications.

"Innumerable treatises on the cultivation of vegetables have been written, but 'The Vege- table Garden' is the first work in any language in which are classified, described, and illus- trated what are the most important of all plants to the human race. It is the production of men who in their work for many years past have had good opportunities of thoroughly study- ing the subject. No excuse is needed for 'making English' such a book-for the benefit, not only of our own horticulture (increasing in interest and importance every year), but also for that of America, and of Australia and our other colonies, in which, happily, the plants herein described may be grown. It will be an aid in erabling us to realise the wonderful variety of light, pleasant, and excellent food now within our reach, and in making many a good vegetable more widely known."—From the Preface.

"Dr. Wace and his able coadjutors have done their work in so thorough, scholarly, and workmanlike, luminous, and yet so readable a manner, that they have left little to be desired.

As it is considered desirable that the notes should be used only in the preparation of the lesson, and not in the class, they are bound up separate from the text. "The idea of publishing the notes separately seems to us a good one in the case of a text-book for schools. The notes can then be employed in preparing the lesson, while the text alone is brought into class. The Eton Horace is a thoroughly sensible and useful book.

SMITH, D.C.L., and HENRY WACE, D.D. 4 Vols. Medium 8vo. £6 16s. 6d. "The value of the work arises, in the first place, from the fact that the contributors to these volumes have diligently eschewed mere compilation; and, in fact, the articles include many really important monographs by highly competent scholars, frequently adding to a summary of what had been already known the results of new and original investigations. Essays of this class deserve the better welcome on account of their comparative infrequency in this country. In these volumes we welcome the most important addition that has been made for a century to the historical library of the English theological student."-The Times. "This noble collection of biographies and treatises ought properly to be reviewed, as it has been compiled, by distribution amongst specialists. Many of its articles, if they were printed in larger type, would make volumes of considerable size, and supply the critic with plenty of hard work. The Dictionary as it stands is a truly noble monument of the best con- temporary English scholarship, in which the two absolutely necessary elements of the perfect historical temper-the conservative and the critical-too often opposed as contraries, are happily blended."-Saturday Review. ** Subscribers are recommended to complete their Sets.

"The excellent edition of Pope, which is now approaching completion, not only supersedes all its predecessors, but to a study of Pope's life and works is absolutely indispensable. . "All that is valuable in the notes of previous editors is preserved; the super fluities and errors only are omitted. " The new Prefaces and Notes contain an extraordinary amount of information, much of which appears for the first time. It is impossible to praise too highly the patient care and painstaking industry with which facts are sifted, omissions supplied, errors corrected. Equally admirable is the ingenuity, combined with wide reading, that has elucidated many passages in the life of the poet and contemporary allusions in his poetry, which were formerly regarded as hopelessly obscure. " Mr. Elwin's chief contribution to the work was his treatment of the questions raised by Pope's correspondence. In this edition are collected more than Four Hundred and Thirty new letters, including letters from Caryll, Oxford, Orrery, Bolingbroke, Bathurst, Broome and Fenton. The size and importance of this new collection would alone rank this edition above its predecessors."—Edinburgh Review. Among Cannibals.
