RIVERSIDE, CAMBRIDGE: PRINTED BY H. O. HOUGHTON AND COMPANY. PREFACE. THE successful application of steam-power to boats and locomotives forms a most important era in the history of this world's progress; and the men who took a part in accomplishing that great work, are entitled to the remembrance of all such as respect human genius, and look upon the advance of knowledge and civilization as a blessing. The subject of this memoir was one of those men, and the interesting incidents relating to his inventions were liable to be lost to history by the lapse of time, and with them his just claims for the essential part he took both in the invention of the steamboat and locomotive engine. To preserve these facts, was indeed the motive that led to the preparation of this little volume. The facts relating to the inventions of Nathan Read, so far as they were spread on paper, were preserved by him during his lifetime, and by his family after his decease; and the reasons why they were not published by himself, will appear in the closing chapter of this book. He having, however, failed to accomplish this end, which is much to be regretted, the question Vi PREFA CE. arose, should the evidence of his labors pass off forever, or be presented to the public? This was a matter that upon every consideration both of a private and public character scarcely allowed hesitation; the truth of history, the dictates of friendship and justice, and the claims of Science to a knowledge of all who have been devoted to her service, seemed to require the publication; and under this aspect of the case the labor of collecting the evidence and preparing it for the press was undertaken by the subscriber, without expectation of fee or reward. And it may be added, that a desire to contribute to the early history of the steamboat and locomotive this additional testimony of the talent and genius of our own native citizens, will also, it is believed, be appreciated by a generous public. In prosecuting our inquiries we have found it necessary to compare the respective claims of inventors; but this occupies no distinct portion of the narrative, and is drawn from the facts here presented, and from the published accounts of various authors; and such extracts as have been deemed proper to elucidate the subject, or to give interest to the reader, have been duly credited, by reference to the authorities. It will be seen that different projectors, supported by different countries, come in as contestants for the honor of these inventions: England, Scotland, France, PREFA CE. vii and Spain, claim the invention of the steamboat; and Fra:ice and England the locomotive engine; when, in truth, they were both inventions of our own country; and it will be left for the reader to decide who among us contributed most toward the invention of that machinery, which resulted in their success. The original descriptions, plans, and drawings of Judge Read, so far as they relate to the subject, have been carefully copied into this volume; and, on inspection, no one will doubt the genuineness of the papers. His manuscripts, in the mean time, contain numerous plans, drawings, and descriptions, of other inventions and experiments in the mechanic arts, made by him. These, and many other matters, would properly come within the scope of a biography, but not within the plan of this work. To show the necessity of a complete revolution in the steam-engine to prepare it for navigation, even after Watt had made his great improvements upon it, a brief account of its invention as it progressed from one step to another, from its earliest history up to the close of Watt's improvements, has been given. The engine of Savary, Newcomen, or Watt, could not be successfully applied to boats; and all attempts made with them utterly failed; which in itself shows the fallacy of all the claims to the invention of the steamboat, before the discovery and existence of ma viii PREFA CE. chinery necessary to give it success. In order to show this, it became important to notice the numerous experiments, both in this country and Europe, with the old form of engine, whether of Newcomen or Watt, or those tried by Rumsey and Fitch; and, to show wherein their failure consisted, to compare their engines with that afterwards invented by Read, which it is claimed was the engine applied by Fulton on his first boat upon the Hudson, and led to the final success of navigation by steam. The same may be said of the numerous experiments with the locomotive engine. All proved unsatisfactory or wholly failed until the multi-tubular boiler and high-pressure engine, which had been invented by Read to fit Watt's engine to the purposes of locomotion, gave triumphant success to the locomotive, as applied by George Stevenson. These various inquiries make up an interesting portion of the volume; and although they may be felt at first to be inapplicable to its general purpose, yet, as the reader progresses, he will see both the necessity and importance of this portion of the narrative; more especially as the design of the work is purely historical.

THE invention of the steam-engine prepared the way for a series of experiments, with a view to apply it to navigation, and at length to land transport. The great improvements of Watt had changed its character from a machine of comparatively small importance, and limited in its application and use to the single purpose of pumping water and lifting ore from the mines, to an instrument applicable to the use of mills and factories, and most kinds of mechanical industry, where a stationary motive power was required. This essential change in the utility of the steam-engine, was effected, not only by reducing the expense of working it, but by converting the rectilinear motion of the old Newcomen engine into a rotary motion, uniform and continuous; which improvement not only made it possible, but a convenient motive power, to turn the wheels of mills and factories. It is very proper here to notice, that the invention of the steam-engine, which in its operative power at this day far exceeds the whole amount of hand labor upon the habitable globe,1 was not the work of one man, or one generation of men; indeed, we may well imagine 1 London Q{uarterly Review, vol. civ. p. 411, 1858. 1 2 NATHAN READ AND THE STEAM-ENGINE. that the force of steam must have been known to some extent, as early as man had the power of observation and fire and water were brought in contact before him. From the time Hero of Alexandria amused himself by the use of steam as a mechanical force to move the simple machinery he had invented, up to the time Watt perfected his improvements and set his double-acting rotary-engine at work, was nearly two thousand years. And although no sensible improvement was made with steam force, before Cardan discovered the effect of condensation, — for the aeolipile used by the Greeks and Romans, and Jack of Hilton, of feudal notoriety, were no improvement upon Hero's invention,- yet from Cardan's day to the time of Watt, a period of some two hundred and ten years, scientific men and men of genius were successively engaged in the work, and adding something towards the invention of the steam-engine. Battista della Porta, Solomen De Caus, the Marquis of Worcester, Torricelli, Pascal, De Garricke, Papin, Savary, Newcomen, and others, not forgetting little Humphrey Potter, each one made some important addition to it. Notwithstanding this, when it went into the hands of Watt it was at best but a very imperfect thing, compared with engines of the present day. To suppose that the steam-engine, steamboat, or locomotive, could be invented by one man, would be contrary to the truth of history. Indeed, inventions in steam-power, and in most cases of like complication and importance, have been progressive. It would be absurd to suppose, that one single mind would be able to acquire, in the first place, so perfect a knowledge of all those intricate principles of natural and mechanical NATHAN READ AND THE STEAMl-ENGINE. 3 science, as it must needs understand, to construct a steam-engine; and in the second place, conceive and put together the several parts of a machine so complex and extensive. Facts show that these inventions are brought about by successive improvements, first by one and then by another. How often do we hear the remark, "Fulton invented the steamboat," as if everything connected with it, keelson, hulk, wheels, and the engine it carries, were new discoveries by him alone. Indeed, to Watt himself, who never had any settled purpose or intention of applying steam power to boats or land carriages,1 and made no special improvements in the engine directed to those purposes, there is due a large item of credit, in both cases, for his inventions. The steam-engine, however, as improved by him, was but partially prepared for navigation and land transport. He gave it the rotary principle,2 without which it would have been useless; but his massive boilers, and great weight of fuel and machinery, were not suited to the capacity of boats and land carriages, nor was the form of his engines adapted to those purposes. His double-acting cylinder and separate condenser, would both apply to boats; but in the case of land carriages it became necessary to dispense with the condenser, the working beam, and some other parts of the machinery, for the want of water fori condensation, as well as the want of space; and a new sort of engine, constructed upon different principles, became necessary for that particular use.3 It is believed that Nathan Read, as early as 1788-89, 1 Muirhead's Life of Watt, p. 330. 2 Ibid. p. 227. 3 Woolhouse On the Steam-enqgine, vol. i. p. 42. 4 NATHAN READ AND THE STEAM-ENGINE. while a resident of Salem, Massachusetts, invented the necessary machinery to adapt Watt's engine to boats and land carriages, with the avowed and special purpose of applying it to both of those objects. That he constructed a model of a steamboat, with paddle-wheels and his improved engine to drive it, being the same machinery, substantially, that Fulton used eighteen years after, in his first experiment upon the Hudson; and being also the first combination of that machinery which gave Fulton his success, and success to the application of steam-power to navigation. That he at the same time constructed a model of a land carriage, to run on common roads (and equally applicable to a railroad-track), and fitted his engine, with special reference to that purpose, upon the high-pressure principle, dispensing with the condenser and working-beam; which machinery was substantially upon the principle as that which gave Stevenson his success, and which is now in use for locomotive engines. The evidence relating to these inventions of Read is mainly derived from the papers he left behind him at his decease, the originals of which are open to the inspection of any who may have the curiosity to examine them, from which the extracts and drawings contained in this publication have been taken. It is proposed to examine this evidence, and compare it with the claims of other projectors. CHAPTER II. NATHAN READ 1 was a native of Warren (formerly Western), Worcester County, Mass., born July 2, 1759. His ancestors originally came from Newcastle-upon-Tyne; they then settled in the County of Kent, where they lived for several generations. From thence they emigrated to America at an early day, about 1632, and settled in the vicinity of Boston, where they resided for many years. His grandfather - when the country was new, and but few settlements in that section of the State- purchased a large tract of land in Warren, upon which he settled, and where he spent the remainder of his life in the improvement of his lands. His father, Major Reuben Read, was an officer in the Revolutionary service; and his mother, whose maiden name was Tamison Eastman, was first cousin to Major-General Nathaniel Greene, of Rhode Island. His father was an only son, and resided upon the homestead during his life. At the age of fifteen years, Nathan commenced his preparatory studies for College, and at the close of the summer vacation of 1777, entered Harvard University. His parents were desirous that he should qualify himself for the ministry, and he 1 The likeness of Judge Read faces the title-page. It was engraved at Philadelphia during his attendance there as a member of the House of Representatives in Congress, in 1801-2, at which time, he was in the fortysecond or third year of his age. The likeness is a very perfect one, and is struck from the original plate, which has been preserved in the faimilv. 6 NATRAN READ AND THE STEAM-ENGINE. attended Professor Sewall's Lectures on the Hebrew. Language. He acquired a good knowledge of the language, and by appointment, gave a Hebrew Oration at a public exhibition of the University; and during the interval between the death of Professor Sewall and the appointment of his successor, Mr. Parsons, he was engaged to instruct the class in Hebrew. He graduated in 1781, on which occasion he was selected to deliver the valedictory address. He was distinguished as a scholar, and left College with the respect of officers and students. After graduating he was engaged in teaching in Beverly and Salem, until 1783, at which time he was elected a Tutor in Harvard University, where he continued his labors as such until the commencement of 1787. He then resigned his place as Tutor, and entered upon the study of medicine with Dr. Edward A. Holyoke of Salem, until October, 1788, when lie gave up the idea of following medicine as a profession, relinquished its study, and opened an apothecary store in Salem. While engaged in the study of medicine with Dr. Holyoke, and also while in his store, he devoted himself, more or less, to study and experiment in the mechanic arts, which indeed held a higher place in his mind than his medical studies or merchandise. It was during this period of time that he invented and constructed his models of a steamboat and locomotive carriage, before noticed. In October, 1790, lhe was married to Miss Elizabeth Jeffirey, daughter of William Jeffrey, Esq., Clerk of the County of Essex, and granddaughter of Joseph Bowdish —August 24th, 17'l1, he was elected a member of NATHAN READ AND THE STEAM-ENGINE. 7 the American Academy of Arts and Sciences - April 4th, 1795, he removed to his farm in Danvers, and built a permanent structure across Water's River, which served the double purpose of a dam and bridge. In 1796, he and his associates erected and put in operation the Salem Iron Factory, for the manufacture of chain-cables, anchors, and other materials of iron, for ship-building, he having the chief superintendence of the work. While thus engaged, he invented and put in operation in the factory, designed for its own special use and benefit, with a view to the saving of labor and other economical purposes, a nail machine, since extensively used for cutting and heading nails at one operation, for which he received a patent, as the original inventor, from the United States Government, on the 8th of January, A. D. 1798. This highly important invention obviated the very great labor and expense of the manufacture of those articles by hand.1 In October 1800, he was appointed a member of Congress for Essex South District, to fill the vacancy occasioned by the death of Judge Sewall, then late member from that district; and in November 1800, he was elected by the people of the district, a member of the succeeding Congress, for two years from and after March 4th, 1801; and was a member during the severe contest in the House of Representatives for the Presidency, between Jefferson and Burr. In February 1802, while a resident of Danvers, he was appointed by Governor Strong a special Justice of the Court of Common Pleas for the County of Essex; and after his removal from Danvers to Belfast in 1 For his specification and patent of the Nail Machine, see Appendix, No. 1. 8 NA THAN READ AND THE STEAM-ENGINE. Maine, which was in 1807, he presided as Chief Justice of the Court in Hancock County for many successive years. In 1815, he was elected an honorary member of the Linnman Society of New England. After removing to Belfast, Judge Read gave most of his time to agricultural pursuits; but he often indulged himself in new inventions in the mechanic arts and trying experiments therein; and during his whole life these and the natural sciences were his favorite study. He invented several useful agricultural implements, for some of which he took a patent; but constructed them mainly because he had use for them on his farm. His farm consisted of some four hundred acres of land, finely situated near the head of Belfast Bay, lying upon the shore just south of the City of Belfast. His residence overlooked the bay, with its attractive scenery; and here he spent the remainder of his life, ever taking a lively interest in all matters of a public character, especially such as were designed to improve the moral condition, and advance the intellectual and social improvement of the people among whom he lived. He regarded the cause of education as involving one of his highest duties; and at an early day, when the town was comparatively new, he was instrumental in establishing a high school in Belfast, that the youth of the place might be educated at home -the beneficial effects of which have long been appreciated. He died at his residence in Belfast, January 20th, 1849, in the ninetieth year of his age, and in the full possession of his intellectual powers, except a few days at the close of his last sickness. He possessed a strong NATHAN READ AND THE STEAM-ENGINE. 9 constitution, and a strong and highly cultivated mind; his aims were high, and he soared above the sordid interests of the world. He never sought to make himself conspicuous, or to give publicity to his attainments or labors, but chose rather unobtrusive retirement. His deportment was always gentlemanly; his form fine, and his countenance highly intellectual. His conversation was ever interesting and instructive; and he lived and died with the respect and esteem of all who knew him. He was the last surviving member of his College class; and with two exceptions, - Judge Farrar and James Lovell, - the oldest living graduate of Harvard University. As early as 1788, as already noticed, while a resident of Salem, he became especially interested in the purpose of applying steam-power to the practical end of propelling boats and land carriages. He foresaw the importance of attaining such a purpose, and set himself to work to contrive the necessary machinery to effect it, which at that time was felt by all intelligent men who had given their attention to the subject, to be a desideratuzm, -a work yet to be accomplished. The idea as applied to boats was not new; various experiments had been tried, but were mainly directed to the mode of propulsion, without so much attention to the motive power; and all the experiments hitherto tried had proved a failure. To show the nature of those experiments, I will briefly notice them in their order, that the reader may judge of the cause of their failure, and of the necessity that then existed of great improvements in the steam-engine, in order to make the application of steam-power to boats and land carriages successful. CHAPTER III. IT has been seen that Watt's double-acting condensing engine, containing the continuous rotary principle, was not introduced to public use in a working form until 1787, which principle, though not so designed by Watt, was one of the necessary prerequisites to a successful application of steam-power to navigation. Hence the inference is beyond dispute, that success in the invention of the steamboat before that time had not been effected. Indeed it will appear, that whatever had been done, both in speculation and experiment, proved that there was no lack of the idea, or want of faith, in navigating boats by steam; but the faith was without the appropriate works. The earliest pretension we have on the subject of steam navigation, has been dug up from the national archives at Simancas in Spain, and purports to be a paper discovered in the year 1825, long after steam navigation went into effect both in America and Europe. The following is a translation 1 of the account, from 1"Navarrete's Coleccion de los Viages," etc., Madrid, 1825:2 " Senior Don Thomas Gonzales has sent me from Simancas the following notice: — 1 Credit is due to the Hon.

"' In spite of the obstacles and opposition which the project met, the Emperor ordered trial to be made, and this in fact took place in the port of Barcelona, on the 17th of June in the year 1543. "'Garay never publicly exhibited his machinery, but at the time of the trial, it was observed that it consisted of a large caldron of boiling water, and wheels of propulsion attached to the two sides of the ship. "' The experiment was tried with a vessel of 200 tons - which had lately arrived from Colibre with a cargo of wheat, - called The Trinity, and commanded by Captain Pedro de Scarza. "' As commissioners on the part of Charles V. and the Prince Philip, his son, there were present on this occasion, Don Henry of Toledo, the governor, Don Pedro Cardona, the treasurer Ranago, the vice-chancellor, the master accountant of Catalonia, ID. Francisco Gralla, and several other persons of condition both Castilians arid Catalans, and among them several sea-captains, who were present at the experiment, some on board, others on the beach. "'In the report made to the Emperor and the Prince, they all agreed in praising the machinery, and particularly the facility of steerage of the ship. The treasurer Ranago, who was unfriendly to the project, states that the vessel would malke but two leagues in three hours; that the machinery was complicated and expensive, and that there was much danger of the frequent bursting of the caldron. The other commissioners declared, that the vessel would put about twice as quick as a galley by ordinary navigation, and that she made at least a league an hour. 12 NATHAN READ AND THE STEAM-ENGINE. "''The experiment being concluded, Garay took out the engine which he had set up in the vessel, and having deposited the wood-work of it in the arsenal at Barcelona, kept the rest in his own possession. "'Notwithstanding the objections raised by Ra:nago, the plan of Garay was approved, and if the expedition in which Charles was then engaged had not prevented it, he would no doubt have encouraged its prosecution. However he promoted the inventor one grade, gave him a compensation of 200,000 maravedis, ordered all his expenses to be paid out of the general treasury, and conferred other favors upon him.

Under those circumstances the account must be taken as true, unless there is good reason to suppose that it found its way into the archives as a hoax, or what would be more likely, as a fraudulent mode of attaching to Spain the credit of inventing both the steam-engine and the steamboat. As we trace the connected history of the invention of the steam-engine, it is, however, extremely difficult to arrive at any conclusion favorable to the authenticity of the account. The experiment of De Garay is stated to have been made in 1543. This was one hundred and fifty years before the steam-engine was so far invented as to be applied to any working purpose, and two hundred and forty years before Watt made it capable of turning a crank, and long before we have any reliable history that steam was ever thought of as a motive power. In 1543, and from that time back to Hero of Alexandria, who lived some one hundred and thirty years before the Christian era, and who was the first to notice the expansive force of steam, of whom we have any account,1. it had never been applied to any mechanical use of moment. Hero, to gratify his curiosity and love of science, conducted steam from an iron pot into a small hollow ball or sphere, with two pipes passing out of it at opposite sides and bent at the ends in opposite directions, through which the steam would escape, and by its reacting force, give to the ball 1 Stuart's Anecdotes of the Steam-engine. 14 NATHAN READ AND THE STEAM-ENGINE. a rapid rotary motion, to the delight of the inventor. (See figures Nos. 1 and 2.) These simple toys, with another more simple still, called the molipile,1 or ball of IEolus, used by the Greeks and Romans, - and we have one account of its being used by the Normans in Staffordshire after the Norman Conquest,2 - constituted all there was of the steam-engine, not only at the time, but for a long time after the reputed experiment of De Garay at Barcelona. The meolipile consisted of a hollow ball of the size of a common pot, made of cast-iron, with a small open pipe connected with the top, and passing off in a horizontal direction. (See No. 3.) By filling the ball partly with water and placing it over a fire, the steam, as it was forced through the pipe, produced a lateral current of air, and thus served for the bellows of that day, for blowing up flame and producing combustion,3 like the blacksmith's bellows of the present day. It being a windy little instrument, was named after LEolus, the god of the winds. The molipile referred to in Staffordshire, was somewhat different in its construction, and used for a different purpose. It was connected with one of the old feudal customs of England, and was called Jack of Hilton. For the amusement of the reader I will give the description of it as related in Plot's "History of Staffordshire." 4 "Yet there are many old customs in use within memory, 1 Vitravius, lib. i. chap. vi. 2 Plot's History of Staffordshire, p. 433. 8 Renwick On the Steam-engine, p. 202. 4 Natural History of Stafcordshire, by Robert Plot, LL.

Now, Jack of Hilton is a hollow little image of brass, of about twelve inches high, kneeling upon his left knee, and holding his right hand upon his head,. having a little hole in the place of the mouth about the bigness of a great pin's head, and another on the back about two thirds of an inch in diameter, at which last hole it is filled with water, it holding about four pints and a quarter, which, when set to a strong fire, evaporates after the same manner as in an molipile, and vents itself at the smaller hole at the mouth in a constant blast, blowing the fire so strongly that it is very audible, and makes a sensible impression in that part of the fire where the blast lights." With these two simple things, representing all there was of the steam-engine at that day, had De Garay suddenly brought one into existence, of sufficient magnitude and power to propel a ship of two hundred tons burden about the Bay of Barcelona, it would seem that an achievement so wonderful before the world would have had some historical mention of it aside from the record which for the first time came to light in 1825. Moreover, with what propriety can we suppose that any single mind, "in the year 1543," a mere twelvemonth, at a period too when the dark ages still cast their shadows over the intellect of man, and 16 lNATHAN REIAD AND THE STEAM-E-NGINE. the arts and sciences were but little known, was capable of grasping the invention, both of the steam-engine and steamboat, and that without any previous invention of the kind to lead the thought to such a conception, or rule or formula, to give direction, in the construction of its complicated machinery? As we look forward from the reputed experiment of De Garay we are still more struck with the difficulties that come in the way of credit and belief in the account. Cardan was the first modern author who makes any allusion to the subject of steam.1 He seems to have had some knowledge of its expansive force; and in the course of some experiments in chemistry he was making he discovered that steam might be condensed and a vacuum thus produced. He gave an account of his experiments in 1576, in a work he then published, - being some thirty-three years after De Garay's reputed experiment. This was the first known step, after Hero's invention of the vaolipile, that led to the invention of the steam-engine, and it was an important step. Battista Porta published a work in 1601, in which he gives some account of experiments made by him in steam; wherein he showed the effects of condensation, and the vacuum thereby produced, by forcing up water to fill the vacuum by atmospheric pressure. He also invented a machine fobr raising water by the expansive force of steam alone; causing it to press downward upon the surface of the water in a cistern, 1 Renwick On the Steam-engine, p. 203; Stuart's Anecdotes of the Steamengine, p. 19. NATHAN READ AND THE STEAM-ENGINE. 17 and thus force it up through a pipe passing down into the water; I and he in the mean time, determined the relative bulk of steam and water.2 His experiments both in mechanism and chemistry, effected another important step in the invention of the steamengine. Solomen de Caus, about forty years after Porta, was the next to make any experiments in steam. In 1641, he constructed a machine to raise water by means of a boiler and pipe, and the downward pressure of steam upon the surface of the water.3 His machine was similar in principle and construction to Porta's, and it does not appear that he made any very great improvements upon it. He sought the patronage of the French government to aid him in his steam projects; and to get rid of his importunities, it is related of him that they declared him a crazy man, and confined him in the Bicetre, the insane hospital at Paris. This was near a hundred years after the reputed experiment of De Garay under the very eyes of the French nation. About twenty years after De Caus, the Marquis of Worcester constructed a steam-engine, worked by the expansive force of steam, and set it to pumping up water in Vauxhall Garden in London.4 This was the first working experiment, ever tried by steam, above the aeolipile, and has given to the Marquis of Worcester the reputation of being the first who invented the steam-engine. It was rude in its con1 See No. 4. 2 Renwick On the Steam-engine, p. 204. 3 See No. 5. Muirhead's Life of' Watt, p. 91. 4 Stuart's Anecdotes of the Steam-engine, vol. i. 1829. 2 18 NATHAN READ AND THE STEAM-ENGINE. struction, and not put to any steady use, but only to show by experiment that steam might be made to fling water into the air some thirty or forty feet, to the astonishment of the London public; and in 1663, - one hundred and twenty years after De Garay's account,he obtained an act of Parliament for his " Water-commanding Engine." 1 Afterwards, when the steamengine became so far improved as to make it a valuable motive power, English and French writers entered into a controversy upon the subject, the former claiming the Marquis of Worcester, and the latter De Caus, as the inventor of the steam-engine - each class of writers prompted by national pride. They seemed to have no knowledge of De Garay's experiment, as no allusion was made by them to the subject. During the very time the Marquis of Worcester was trying his experiments, and following thereafter, a school of illustrious men in Europe were engaged in scientific study and experiment. Galileo, who was by the Inquisition and the rack forced to renounce those truths in natural science which he had discovered, conceived the true nature of a vacuum, and communicated his ideas to his pupil Torricelli; who after the death of Galileo carried out the suggestion by a series of experiments, in which he succeeded in producing a more perfect vacuum,2 and in the mean time invented the barometer. De Guericke 3 meanwhile invented the air-pump, and also the cylinder and piston; he exhausted his cylinder with the air1 Muirhead's Life of Watt, p. 93. 2 Ibid. p. 101; Cyclopcedia of Biography, p. 312. 8 De Arte Mechanicd Hydraulicopneunmaticd, 1657. NATHAN READ AND TIE STEAM-ENGINE. 19 pump, and established the principle of atmospheric pressure by means of the piston. Pascal determined the weight of the atmosphere by its pressure upon the piston, and the variation in its weight at different altitudes.1 Boyle also invented an air-pump, and assisted Torricelli in making his experiments at Florence. They together constructed a machine to raise weights by atmospheric pressure alone, which was the origin of the atmospheric engine.2 But it does not appear that any of these distinguished men attempted to produce a vacuum by condensation, which idea all this time rested with the suggestions of Cardan and the experiments of Porta. Yet the discoveries they severally made were not only necessary, but furnished important steps in the invention of the steam-engine. The danger of explosion from the expansive force of steam, during these experiments had been discovered; and Denys Papin,3 in 1688, to remedy the difficulty, invented the safety-valve, one step more in the invention of the steam-engine. He also attempted tc produce a vacuum by rarefying the air in the cylin der by heat, then to raise the piston by the explo sive force of gunpowder. These failing, he built a fire under the cylinder, which he partly filled with water, and found the steam would lift the piston to the top, and by removing the fire, as the steam cooled, the piston would fall. But the idea of applying and removing his fire from under the cylinder, every time he gave an upward and downward motion to the 1 Nouvelli's Exp&riences touchanst le inde. 2 Muirhead's Life of' Watt, p. 101. s Arta Eruditorum, 16S 3 and 1690. 20 NATHAN READ AND THE STEAM-ENGINE. piston, presented a practical difficulty that discouraged him; and he gave up the subject for the time being. Some ten or twelve years after, Savary 1 happened to think that Papin's difficulty might be overcome by having a boiler separate from the cylinder, and by applying cold water outside the cylinder to cool the steam within it more rapidly. This worked better, but gave no practical importance to the engine *as a working power, but plainly disclosed the fact that its utility depended on some contrivance to pro-'duce a sudden condensation, which would give to the piston a motion upward and downward equally sudden. Savary, however, did not succeed in effecting this grand purpose; but his experiments were highly important in the progress of the invention, for which he obtained a patent by act of Parliament, in 1698;2 and drawings were made of his engine - being the first known time the steam-engine was represented on paper. The next advance in the progress of this invention was made by Newcomen and Cawley, in 1705. They inclosed the cylinder with another of larger size, with a space between of eight or ten inches for cold water for condensation - an improvement upon Savary's plan of affusing cold water on the surface; - they also applied leather packing to tighten the piston, and covered the top of it with water resting upon it for the same purpose, and improved the engine by attaching eduction-pipes, valves, cocks, and a variety of small 1 Phil. Trans. Abr. vol. iv. 198, A. D. 1699. 2 Woolhouse On the Steam-engine, pp. 5, 6, 7. NATHAN READ AND THE STEAM-ENGINE. 21 and ingenious work, to give the machinery a more perfect action. They also invented the working-beam, and by a mere accidentl discovered the process of injecting cold water into the cylinder for condensation, without which the condensing engine must have remained comparatively useless. Noticing that the piston moved with more rapidity and force than usual, they searched for the cause, and discovered a hole through the piston where a plug had worked out and let the cold water into the cylinder. A sudden condensation of the steam and more rapid motion of the piston was the result. This opened to their minds the idea of injecting cold water into the cylinder - which plan was thereupon adopted. They invented and applied for that purpose the injection-pipe, with its ingenious apparatus, through which a jet of water was flung directly into the cylinder, and the steam almost instantaneously condensed. This gave a corresponding movemnent to the piston, and the steam-engine, for the first time, if I am allowed the expression, had the breath of life breathed into it and became a living soul. This invention made way for another, equally curious and of much importance. The injection-pipe and apparatus above mentioned, were controlled by two valves, the one opening and the other closing alternately, and controlling the action of the engine. These valves were worked by hand brakes, and being easily done, they usually employed a boy to tend them. A lad of the name of Humphrey Potter,2 getting tired 1 Deragulier's Ex. Phil., vol. ii. p. 533. 2 Muirhead's Life of Watt, p. 119. Renwick On the Steam-engine, p. 220. 22 NATHAN READ AND THE STEAM-ENGINE. of his work, took it into his head to attach the brakes or handles that worked the valves to the working beam, and leave them to be moved by its alternating motion, while he could rest his weary self and enjoy his play. This incident resulted in the invention of the scoggin (and afterwards the governor), which not only gave a more regular and uniform motion to the piston, but increased its upward and downward movements from about eight to sixteen times in a minute, thus doubling the effective power of the engine. It thus became, with the exception of fire to feed it, a self-governing machine, settling at once upon that degree of motion which the most free injection of steam, and sudden condensation, could give to it. It was now thought that the steam-engine was perfected; and the young Hercules, though rough and clumsy in its workmanship, and awkward in its movements, was. for the first time, of which we have any knowledge, set to work in good earnest pumping water and raising ore from the mines. The engine of Newcomen, however, was far from being perfect, either in the principles of its construction, or in its workmanship. It was yet incapable of propelling a boat or locomotive engine, yet it labored away in the mines and nowhere else, for the next eighty years, without any essential improvement.1 Smeaton, however, improved the finish and proportions of the machinery and constructed an engine, from which he made a table of proportions for the use and benefit of mechanics engaged in their construction.2 It may be 1 Muirhead's Life of Watt, chap. xix. 2 Smeaton's Reports, vol. i. p. 223, and vol. ii. p. 338. NATHAN READ AND TEIE STEAM-ENGINE. 23 well to observe that the engine of Newcomen was moved by atmospheric pressure alone, and steam was used for no other purpose than as a means of producing a vacuum, not even to force up the piston, which was raised by a counterpoise or weight; it is hence called the atmospheric engine. Such was the condition of the steam-engine, when it came into the hands of Watt, its great improver. The first step taken by Watt 1 was directed to a more economical use of steam, and to that end he entered upon a series of experiments to determine whether the estimated densities of steam and water were correct. He found that water when changed into steam expanded from seventeen to eighteen hundred times its bulk; and on this calculation ascertained that six times as much steam as was necessary was used at each movement of the piston. He invented the condenser, a vessel separate and distinct from the cylinder, to remedy this great waste of steam. The steam was conducted into the condenser before it was cooled, and he thus kept the cylinder hot; at the same time he closed the upper end of the cylinder, and added another induction-pipe, making one above as well as below the piston, by which the steam was alternately let into the cylinder, as the piston rose and fell; and substituted steam force, instead of atmospheric pressure, for forcing the piston down, and in lieu of the weight for forcing it up. These improvements gave twice the power at less than half the cost of the Newcomen engine. In 1769 a working-engine was constructed after this plan'. 1 Muirhead's Life of Watt, recently published, we regard as the best authority in relation to Watt's improvements. 24 NATHAN READ AND THE STEAM-ENGINE. Soon after this, Watt entered into copartnership with Mr. Boulton of Birmingham, and the distinguished firm of Boulton and Watt was thereupon established. Boulton was a man of fortune, and liberal withal, and Watt now had every facility to give free play to his inventive powers; and he handled the steam-engine as a half-finished thing. He readily saw, if it could be so constructed as to be used in mills and factories as well as in the mines, it would vastly extend its usefulness and increase its demand. This could only be done by giving it a continuous rotary motion, and thus enabling it to turn a shaft or wheel with uniformity, and to overcome the dead points of the piston, or momentary state of rest at each end of the cylinder, in reversing its movements. To accomplish this desirable end, he constructed an engine with two cylinders instead of one; and applied his steam force to two cranks on the same shaft set at an angle of one hundred and twenty degrees from each other, with a fly-wheel and weight on the periphery of the wheel, at an angle of one hundred and twenty degrees from each crank. But since the above invention of the double engine, it has been found that the double-acting cylinder, and single crank, with the fly-wheel, are all that are requisite to give this motion. He also invented the parallel motion, by which the angular motion of the piston-rod, hitherto worked by a rack and chain attached to the end of the working beam, was changed to a direct rectilineal motion. This was looked upon by other engineers as a curious "mechanical puzzle," and Watt himself said, " that he NA THAN READ AND THE STEAM-ENGINE. 25 was more proud of his parallel motion than of any other invention he ever made." 1 He also invented the throttle-valve, by which, from the action of the engine itself. the same amount of steam always entered the cylinder, and gave a steady, uniform motion to the spindles used in the manufacture of cotton and other fibrous substances; and to regulate those valves without personal attention, he invented that elegant and ingenious part of the steamengine, the governor, by which the steam is cut off from the cylinder as the engine increases in motion, or is let in as it decreases, until their action and the action of the engine are balanced. He also invented the counter, gauge, and indicator, all useful in their place. It was a slow process to construct the first engine, after these inventions were completed, embracing as it did these new, curious, and complex additions to its machinery, without any rules, plans, or drafts for them, other than such as lay in Watt's own head, - his marvelous, unrivaled, inventive brain, - and they were four years constructing the first engine designed for sale. This was completed in 1786, and put at work in the Albion Mills in 1787. Thus Watt, who, to use the words of Sir James Mackintosh, "stood at the head of all inventors in all ages and nations," by one invention after another at length succeeded in completing his double-acting rotary condensing engine, but far, even yet from being fitted for propelling boats or land carriages. I have thus gone through with a concise account of the invention of the steam-engine, from the experi1 Muirhead's Life of Watt, p. 242. 26 NATHAN READ AND TEE STEAM-EATGINE. ments of Hero to the time Watt completed his improvements, for the purpose of showing how difficult it would have been for De Garay or any one individual to have conceived this whole invention, and so far perfected it in the short time of five or six months (as the account shows) as to have brought it to a practical working condition, for any purpose; much more to have applied it also in the same space of time to the propulsion of a vessel of the size spoken of in De Garay's experiment. In addition to the above it is proper here to notice, that the account of De Garay presents the only instance in which Spain pretends to have taken any part either in the invention of the steam-engine or steamboat. After the reputed experiment of De Garay, and during that period of time when these inventions were in progress, embracing some two hundred and sixty years, and while France, Italy, Germany, Great Britain, and the United States were all more or less engaged in the work, and making their contributions to it, Spain, for aught that appears, was wholly insensible to the subject. This surely does not look as though she had at a former day interested herself in the matter: if so, her genius had departed.' 1 Since the above was written, I have been informed that the paper referred to, purporting to be found in the archives at Simancas, has been proved a forgery. - AUTHOR. CHAPTER IV. As we proceed with the invention of the steamboat, we find that the thought of applying steam to navigation was entertained by nearly all the principal projectors of the steam-engine. De Caus,' the Marquis of Worcester, Sir Samuel Morland, Papin, Savary, Newcomen, Watt, and others, entertained the idea that it might be so applied, but no one of these individuals ever made the attempt to try it. Paddle-wheels had occasionally been used from an early period to propel boats by animal power, even by the Egyptians, and afterwards by the Greeks and Romans; and the latter in one of the Punic wars are said to have transported their troops to Sicily on boats with wheels turned by oxen. Valturius in his " Science of War," published in 1472, speaks of this mode of transportation. They were also mentioned by William Bourne in 1578.2 And Prince Rupert, after retiring from his military life, turned his attention to scientific pursuits, and about 1680, constructed a boat upon the Thames, propelled by paddle-wheels, which were moved by horses,3 and others used them in like way. So it is quite evident that the use of wheels of some sort, moved by 1 See De Caus' Book, Les Raisons des Forces Mouvantes, etc. Paris, 1615. 2 Muirhead's Life of Watt, p. 330. 8 Papin's account from Acta Evuditorum, Leipsic, for 1690, pp. 410414. 28 NATHAN READ AND THE STEAM-ENGINE. animals to propel boats, was an old matter, but the application of steam-power to paddle-wheels was of more recent origin. It is claimed in England, " that one Jon. Hulls,1 on the 21st of December, 1736 (the same year Watt was born), obtained a patent from Parliament for what may strictly be considered a steamboat." Hull's theory - for it appears he never tried any experiment - was certainly a very ingenious one.2 He published a pamphlet which he entitled, " A Description and Draught of a new invented Machine for carrying Vessels and Ships out of or into any Harbour, Port, or River, against Wind and Tide, or in a Calm." He made a drawing of his proposed boat, from which it appears that he intended to use one paddle-wheel in the centre of the stern of the boat, to be turned by means of ropes and pulleys, so arranged as to give his wheel a continuous rotary motion.3 The plan of his boat has but little resemblance to a steamboat; and his machinery would lack the two essential qualities of strength and durability. He intended it only for towing other vessels out of or into harbors, and designed to move it by the Newcomen engine, the only engine then in use, and that so imperfect as to be in no way adequate to the 1 Woolhouse On the Steam-engine, vol. i. p. 14. Wooderoft's History of Early Steam N2avigation. 2 Hulls' engine: Let a, b, c, be three wheels on one axis, and d, e, two wheels bore on another axis. A with ratchets so as to move the axis only when they move forward; f, g, h, are three ropes, and P is the piston of the engine. When the piston descends, the wheels a, b, c, move forward, and the ropes g, h, cause the wheels c, d, to move the wheel e forward and the wheel d backwards, and the latter raises the weight G, which moves the wheel d forward during the ascent of the piston; consequently the axis A, B, with the paddle-wheel, would be constantly moved round in the same direction and be an equable force. (See No. 6.) 8 See plan, in Woolhouse On the Steam-engine, p. 15. NATHAN READ AND THE STEAM-ENGINE. 29 purpose designed. It is evident Hulls never built a boat or tried to put his theory into practice; had such been the case, English writers, in their zeal to prove him the inventor of the steamboat, would not have failed to mention it. His plan was no doubt found impracticable and abandoned; yet it showed that not only the idea of applying steam to boats was entertained by Hulls, but that he drew a plan on paper, of such machinery as he had invented for that purpose. Belidor, an eminent writer and engineer, who gave an account of the steam-engine in 1739, two years after Hulls published his pamphlet, makes no mention of him.1 In 1753, sixteen years after Hulls published his pamphlet, Daniel Bornouilli, who sought to propel boats by ejecting water from the stern, gained a prize from the French Academy of Sciences, for demonstrating to the Academy the point that steam-power, as then understood, could not be successfully applied to navigation, without a continuous rotary motion,2 which it did not possess. This looks as though Hulls' rotary mechanism could not have been regarded of much if any importance. This, however, was not the only difficulty, the enormous amount of fuel required to run the Newcomen engine for any length of time, was beyond the capacity of a boat to hold or carry. Yet others, not seeing these fatal difficulties in their way, still persisted in trying their experiments with it. Genevois, in 1759, tried a boat with the Newcomen engine and paddles, constructed after the fashion of a 1 Arch. Hydr., tom ii. pp. 300, 331. 2 Remwick On the Steam- engine, p. 279. 30 NATHAN READ AND THE STEAM-ENGINE. duck's foot, opening in its backward and closing in its forward motion through the water.1 But he soon found that art would not construct from inert lifeless matter, a paddle that would work with the elasticity of the living sinews, joints, and filaments constructed by nature. The Comte de Auxiron in 1774, and the Earl of Stanhope afterwards, made similar trials, but with no better success.2 Perrier in 1775, it is said, tried paddle-wheels, but he copld not make engine and wheels go together, and ascribed his failure of success to the wheels, which he flung aside, and tried other modes of propulsion, but discovered no plan of success.3 The Marquis de Jouffroy, in 1782, constructed a boat at Lyons, one hundred and forty feet long, fifteen feet beam, and drawing three and a half feet of water; and launched it upon the Soane, where he experimented with it for more than a year.4 He used paddles, which together with the defects in the prime mover, could not be made to work to his satisfaction; and the boat, after a long and thorough trial, was given up. But Jouffroy was entitled to great credit for his energetic experiments, and failed because the right sort of engine and propelling machinery were wanting. The next experiment in Europe, worthy of notice, was tried by Patrick Miller of Dalswinton in Scotland, in 1787.5 He put three small boats or skiffs together, side by side, making a triple boat, and placed paddle-wheels between them, to be turned by cranks, worked by men. This craft was built for a little pleas1 Renwick On the Steam-engine, p. 279. 2 ibid. 3 Ibid. 4 Dictionnaire de Physique, Art. "Chaloupe a Vapeur." 5 Woodcroft's History of Early Steam Navigation. NATHAN READ AND THE STEAM-ENGINE. 31 ure boat upon Loch Dalswinton, a small lake upon his estate. It was moved about the lake with safety, but its slow movements were somewhat monotonous. One James Taylor suggested to Miller the idea of putting a steam-engine into the boat, and in 1788, he employed William Symington to construct a small engine for that purpose, which he put into the boat in the autumn of that year. He succeeded in moving the craft about the lake much faster than by hand, and more to his amusement and satisfaction. This induced him to employ Symington to put an engine into a larger boat, on the Forth and Clyde Canal. This craft was constructed by putting two boats side by side, and having but one wheel placed between them, thus forming a double boat instead of triple.1 The next year, December 26, 1789 (the year after Read commenced his improvements,'it will be noticed), Miller tried his boat upon the canal. They applied their steam force to it, and it is related, succeeded in driving it at the rate of seven miles per hour, a speed not before attained.2 This, however, must have been the result of a short and violent effort, beyond the capacity of the boat and machinery, for we learn that both kept breaking and coming to pieces, until the boat was in danger of sinking, and they run her ashore. Miller quarreled with his engineer respecting it, took out the machinery, and gave up any further experiments in steam navigation. It does not appear how his engine was constructed; but it is evident, if Symington had invented such new machinery as to adapt the steam1 Wooderoft's History of Early Steam Navication. Woolhouse, p. 31. 2 Woodcroft. 32 NATHAN READ AND THE STEAM-ENGINE. engine to boats, he would have made it a prominent point in the account of his experiment. Let his engine be what it may, the very form of his boats, and mode of applying his propelling force, were fatal to a successful navigation. Instead of moving one boat with two wheels, he substantially undertook to move two boats with one wheel; and when we consider the obstruction his double boat would meet with, from the dead water to be dragged along between the hulks, it is evident it could not possess much power or speed; nor did it possess that combination of machinery in any respect necessary to success. To show the correctness of this position, Symington afterwards,1 with ten or twelve years' experience added to his profession, was employed by Lord Dundas (in 1801) to build a steam towboat on the same Forth and Clyde Canal, which he called the Charlotte -Dundas; and this boat did not exceed on the average three and a half miles per hour; and the experiment was given up. Indeed steam navigation was not introduced into Europe for several years after it had been invented and put in successful operation in the United States. The first boat built outside of this country, which can properly claim the name and character of a steamboat, was built in Great Britain by one of Fulton's workmen, Henry Bell, at his own cost and risk, and put in operation on the Clyde at Glasgow, in 1812.2 This boat called the Comet, was only forty feet long, and carried twenty-five tons, with a four-horse engine, and run as a passenger boat between Glasgow and Green1 Life of Watt, p. 332. Woodcroft On Steam Navigation, p. 55. 1848 2 Woolhouse, vol. i. p. 470. NATHAN READ AND THE STEAM-ENGINE. 33 ock. British writers attempt to lionize Bell, and make him the true inventor of the steamboat. Woolhouse says 1"Bell sent a description of the method of applying steam in propelling vessels against wind and tide, to all the em. perors and crowned heads of Europe, and also to America, which last government put it in practice in the year 1806." The above paragraph is recorded in an English work designed as a standard authority, and as the author himself styles it, " a splendid national work." But most surely the United States government was never indebted to Bell for its steamboats; it had not then been much of a steamboat-builder; and we must be allowed to question its'" practice " of building them after Bell's plans, or the plans of any one else, as early as 1806, before they came into use at all. The learned author, however, has the candor to remark, that"British genius and industry have not been extinguished by transplanting to another climate. The projects of the Americans are seldom founded on the sober reasoning of science. Time will, however, check this evil, and he may expect them to hold that rank in the new world, which Britain has held with so much honor for centuries in the older portion." And he adds, - " Considering the importance to America of navigating her immense rivers, it is not surprising that the application of the power of steam to propelling vessels, should by persevering efforts have been first carried into successful practice in that continent." 1 Renwick On the Steanz-engine, p. 277. 3 34 NATHAN READ AND THE STEAM-ENGINE. Woolhouse, however, does not proceed to attribute to any special cause our invention of the cotton gin, nail machine, card machine, block machine, and machine for turning irregular forms, and other inventions and discoveries too numerous to mention, -saying nothing of the great discoveries in electricity by Franklin, and of the magnetic telegraph by Morse, inventions that place this above all other countries for its inventive genius and improvement in the mechanic arts. As we descend from Woolhouse's " National Work," to the current literature of England, we find repeated instances of British writers, in attempting to attach to their countrymen the credit of this invention. An article in the " London Journal of the Society of Arts" will suffice as a sample. It was published in that leading English journal of art as late as 1853. It says, "The steamboat was Watt's invention, and about a score of years ago (which would be 1833 1) it was first put in practice in Scotland, whence it spread over the world." Thus, with very little ceremony, the invention of the steamboat, and the vast spread of steam navigation throughout the world, is, by a single paragraph in the " London Journal," added to the laurels of Great Britain. The paragraph lacks nothing but truth to entitle it to credit and make it complete upon the face of it; but the assumption is so notoriously extravagant as to be innocent of harm. It is also claimed in England, that Robert Fulton, in 1 The writer of the above article was unfortunate in placing his invention and first experiment with a steamboat, twenty-six years after Fulton put his boat upon the Hudson, and long after boats were introduced the world over! NATHAN READ AND THE STEAM-ENGINE. 35 1804, inspected Symington's boat, Charlotte Dundas, and got his ideas of river navigation, with plans and drawings, from him.' Symington's and Fulton's boats and machinery scarcely resembled each other; and Fulton had ordered his machinery of Boulton & Watt, and gave them draughts, long before he ever saw Symington's boat.2 The " London Quarterly Review " (vol. xix. po 353), to make it appear that Great Britain should have the credit of inventing the steamboat, says,' "Miller, of Dalswinton, in 1787, published a book on applying paddle-wheels with cranks to move boats on canals, and suggested using a steam-engine to turn the cranks; and that Miller transmitted a copy of this book to General Washington." Miller's triple-boat, built of three skiffs placed side by side, with wheels between them, and cranks turned by the hands of his servants, was used to amuse his children in a safe way, on a small lake or pond.3 It appears that he made a drawing of this boat and published a description of it,4 with his men tugging away at the cranks. His description of this thing, is the book referred to in the " London Quarterly," as proof that a steamboat had been built at that date in Great Britain. Neither steam nor the steam-engine had anything to do with this craft when Miller published his book or description of it. It does not appear from the " Review" that he published any book after his disastrous experiments with steam. That he sent a copy I Renwick On the Steam-engine, p. 285. 2 On this subject see post. 3 Ante. 4 Muirheacl's Life of Watt, p. 332. 36 NATHAN READ AND THE STEAM-ENGINE. of his book to Washington, might have been true: as the war between the two countries had closed, and the animosity which the British people and government had entertained against us had partially ceased. If Miller ever sent a copy of his book to Washington, containing a scientific description and drawing of his craft! it would seem that the latter would have suggested the subject to Rumsey or Fitch, both of whom at that time were soliciting his aid and advice in their steamboat projects. It is also said that Bell furnished Fulton with plans and drawings in 1806; 1 this is disproved also by the fact, that Fulton had closed his experiments at Paris in 1803, and ordered his engine in 1804, with drawings and directions as to the manner of constructing it.2 In fact, Symington's boat differed from Fulton's so essentially as to bear no comparison; while Bell, instead of furnishing a pattern to Fulton, built his own boat in 1812, after Fulton's. The zeal of English writers to attach the honor of this invention to their own country, is very natural; but they fail to produce any decisive impression on the intelligent public. That many experiments were made in England as well as in France, tending to accomplish that end, is very certain; but that it was finally accomplished by American genius, and in American waters, is allowed by universal consent. 1 Renwick, p. 288. 2 Muirhead's Life of Watt, p. 334. CHAPTER V. WE will now change the scene of these experiments from the opposite side of the Atlantic to our own shores, and trace the progress of this invention in the United States. James Rumsey, a native of Maryland, and John Fitch of Windsor, Connecticut, were the first in America who made the attempt to propel boats by steam. They were sharp competitors in the project of applying steam to river navigation; and were engaged simultaneously in their experiments. Their machinery, however, with which they proposed to propel their boats, was very different both in plan and construction from each other. The first effort made by Rumsey, he did not apply steam as the motive power. His boat was constructed with two keels, having a wheel between them, which he designed to move by the force of the current alone, and to which he attached setting poles by means of a shaft, and cranks to work them; hence he calculated his boat would go best against a pretty swift current; and as may be seen where there was no current it would not move at all.1 This curious theory, however, was soon abandoned, after his attempt to reduce it to practice; but in justice to Rumsey it is proper to say that he intended the boat to run against the currents of rapid rivers only.2 This experiment was in 1784. He afterwards constructed a boat to be 1 Documentary History of New York, vol. ii. p. 1014. 2 ]bid. 38 NATHAN READ AND THE STEAMLI-ENGINE. propelled by steam; and in December 1787, tried it upon the Potomac, at Bath, Berkeley County, Virginia.' He had but very indifferent success, moved his boat but a short distance, and the season closing the river, his boat was laid up, and he made no further experiment with it. The next year he went to England to prosecute his steam projects there; and suddenly died with apoplexy, as he was about to address a crowded audience at Liverpool on the subject.2 Rumsey's steamboat was constructed essentially after the plan of Bournelli, being a mode of propelling a vessel by forcing water out at the stern by the power of steam, through a trunk which extended aft from near the bow.3 Rumsey probably obtained the idea from Dr. Franklin, who was his friend and patron. Franklin, during his residence in France, had taken the opportunity to look into scientific matters of this sort as well as others, and became acquainted with Bournelli's plan.4 He returned from France in August 1785, and in December following laid a plan of a steamboat before the Philosophical Society at Philadelphia, substantially after that plan, and similar to that which Rumsey afterwards constructed. The water was drawn into the forward end of the trunk from under the boat by means of a pump or cylinder, with the piston worked by the engine - the pump containing a valve that opened and closed to draw in the water and force it into the trunk and out at the stern.5 John Fitch, as early as 1785, commenced his steam1 Documentary History of New York, vol. ii. p. 1020. 2 Hows' History of Virginia.

He thus became a rival of Rumsey in the purpose of river navigation - the object they both then had in view. They entered into a bitter controversy on the question of priority, each claiming to be the first to propose steam power to the propulsion of boats.2 They not only claimed priority as it- respected each other, but as to the whole world. Fitch says "he never heard of such a thing as a steam-engine before he had conceived the idea of one," which was in the spring of that year in which he commenced his steamboat projects, — 1785,3 And he says moreover, "The propelling of a boat with steam is as new as the rowing of a boat with angels, and I claim the first thought and invention of it." 4 With these two confessions of Fitch, showing his entire ignorance of the mechanism of the steam-engine, or of any attempt by others to apply it to boats, when he began, it is certainly remarkable that he succeeded as well as he did in. his experiments. He says moreover, in a petition to Congress, as late as July, 1790, in referring to his former experiments, -" That his loss of time and money was occasioned by his total ignorance of the improved state of the steam-engine, for not a person could be found who was acquainted with the minutiae of Boulton & Watt's new engines; and whether your petitioner's engine is similar or not to those in England, he is at this moment totally ignorant."5 1 Westcott's Life of Fitch, p. 119. 2 Documentary History of New York, p. 1012, and post. 8 Westcott's Life of Fitch, p. 119. 4 lbid. p. 172. 5 Ibid. p. 299. 40 NATHAN READ AND THE STEAM-ENGINE. From the above statements of Fitch, it is evident, he knew little or nothing of the great improvements of Watt upon the steam-engine, or of any just method of adapting it to steam navigation. Fitch first proposed to build his boat after the plan of Bournelli, as presented by Franklin to the Philosophical Society; and ordered the hull to be built on that plan,' - of course with a double kelson. But Henry Voight, whom he had employed to assist him in building his engine, persuaded him to give up that plan for some other mode of propulsion; but proposed as the first object to build their engine. Fitch & Voight accordingly went to work and constructed a small engine for a model, of only one-inch cylinder.2 But it had not sufficient force to overcome the friction, and give it self motion. They then made one with a three-inch cylinder, and tried a small skiff by hand with paddles, and one or two other modes, none of which gave them satisfaction. This experiment was in July, 1786.3 Soon after the above trial he applied cranks to his oars or paddles, and found that they worked better. They then put the engine into the skiff, and the experiment was sufficiently satisfactory to induce a part of the company who were aiding Fitch, to believe that a boat of larger size might be safely built. There is no very definite means of knowing the nature of the engine they used. It however appears that it had a double-acting cylinder and cranks; that " each stroke of the piston turned the axle-tree about two thirds round, and each revolution of the axle-tree moved twelve oars, six on a side, with three up and three 1 Life of Fitch, p. 157. 2 ibid. p. 158. 3 Ibid. p. 159. NATHAN READ AND THE STEAM-ENGINE. 41 down, rising and falling about five and a half feet." 1 The oars worked perpendicularly and made a stroke downward into the water like the paddles of a canoe." 2 It does not appear that they used the fly-wheel to carry the motion beyond the dead points of the crank, or that the several parts of the engine were properly proportioned to each other - which, as they worked without any formula, could not by anything other than accident, have been the case. The caps of the cylinders were made of wood, and neither these nor the piston could be made air-tight. They used a condenser invented by Voight, which he called the " pipe condenser." Several other forms of condensers were tried and flung aside; the steam valves worked badly;3 the boiler was of very large size compared with the rest of the engine; said to hold five hundred gallons of water, while the engine and boiler occupied about two thirds the length and size of the boat. It was calculated the boiler and other machinery would weigh from five to seven tons, beside fuel; while the boat was but forty-five feet long and twelve feet beam.4 Yet they succeeded in moving this craft when under full way, from three to four miles per hour, but frequent stoppages were made to accumulate fresh supplies of steam and repair the engine: " for as one defect was remedied another became apparent."5 All this makes it quite evident that they had not hit very near Watt, in the construction of their 1 See Fig. No. 8. 2 Life of Fitch, p. 177. 3 Westcott's Life of Fitch, p. 185, and2post. 4 See affidavits of William Askew and Henry Bedinger, Documentary History of New York, vol. ii. pp. 1024, 1025. 5 Life of Fitch, p. 186. 42 NATHAN READ AND TEE STEAM-ENGINE. engine or made any improvement in the massive boiler, to fit it for steam navigation. This experiment was in July and August 1787. No further experiments were made with the above described boat, but it was abandoned and a new boat built sixty feet long and eight feet beam, in 1788; and the machinery of the old boat taken out and put into this; at the same time the oars of the old boat were dispensed with and substituted by three or four paddles, much broader than the oars, and used at the stern, instead of the sides of the boat.1 They went from Philadelphia to Burlington, twenty miles, and the boiler sprung a leak just as they arrived at the latter place. This was the first trip of that distance ever made by a steamboat known in history, which was the last of July or 1st of August 1788.2 They repaired up the boat and made three or four trips that fall to Burlington, on an average speed of about four miles per hour. This speed did not meet the expectations of' the company, and most of them, with Voight, gave up the project.3 Fitch however got up another company in the spring of 1789, and began another boat with an eighteen-inch cylinder. A condenser invented by Dr. Thornton was put into it; they then tried Voight's pipe condenser with no better success. These changes occupied the summer, but in December they tried the new boat, after enlarging the air-pump. Yet this boat succeeded no better than the old one, and it was laid up for the winter.4 In the spring following, 1790, they tried 1 Life of Fitch, p. 248, and post. 2 Ibid. p. 250. 3 Ibid. p. 252. 4 Jbid, p. 270, and post. NATHIAN READ AND TEI~ ST~EAM-ENGIVNE. 43 another sort of condenser, and wholly failed to work the boat. This was the seventh condenser they had experimented with, all of different construction and of their own getting up — clearly showing how they worked in the dark, without any specific knowledge of the steam-engine as improved by Watt. Another condenser of Fitch's contrivance, however, was tried; and on the 16th of April, as Fitch expressed himself, 66 They reiglnedl Lord High Admirals of the Delaware."' The boat run on the average about six miles per hour; and now and then was brought up to the speed of seven or eight miles. It was run as a passenger boat between Philadelphia and Trenton three months or so; 2 but from the crude and imperfect character of the machinery, thl ill adaptation of one part to the other, the clumsy working of the paddles behind, the great expense of fuel, and the little space on the boat except what the engine, boiler, and fuel occupied, the attention required to keep it in repair, as the machinery kept continually getting out of order, and the expenses of running the boat constantly accumulating beyond its earnings, all together, made it a losing business, and it was abandoned.3 The difficulties Fitch labored under, not only from his owln lack of information, as to the true philosophical data and structure of the steam-engine, and the perplexities he constantly met, while groping in the dark to construct his machinery, were made apparent in this experiment. Nevertheless, it is a fact that Fitch, with machinery that never could be profitably or successfully applied to navigation, even upon the rivers, fo red 1 Life of Fitch, p. 281. 2 Ibid. 284, and post. 3 Ibid. p. 285. 44 iNATIAN READ AND THE STEA-ML-ENGIiNE. his boat at a greater speed than did Fulton in his first experimnent upon the Hudson; but Fulton had got upon the right track, where his path was felicitous and smooth; while Fitch rushed headlong against fatal and unforeseen obstacles. Fitch made some feeble attempts to renew his experiments, but without success. He quarreled with Voight and his friends, who had now lost their confidence in him, and he could raise no funds but now and then a few dollars out of pity to relieve him of his extreme necessities. Thus far his career had been of a remarkable character, just such as would be likely to follow the efforts of such a man. He combined w-ith a rare and remarkable genius, qualities that were fatal to his success. His genius had to contend.yith his ignorance, excitable temper, and intemperate habits, - an array of difficulties that it could not overcome. He was ever groping in the dark, urged on by his impulses, and thus subjected himself to a life of successive calamities. He had conceived the idea of a steam-engine, and of its results when applied to boats, as he says; and set himself to work to build one and make the application. His plans and drawings, taken from his own crude mind for the most part, were necessarily vague and imperfect; and the machinery forged friom them would work badly or not at all, perplex him, and discourage his employers. Had Fitch taken the same pains that George Stephenson did - who at the age of eighteen could neither read nor write —to acquire an intimate knowledge of his profession, and direct his genius by scientific principles, his career no doubt would have been equally successful NATHAN READ AND THE STEA-M-ENGINE. 45 and glorious. Success would have raised him above himself, kept down his petulance and ill-temper, and overcome the evils of dissipation; it would have made a man of him, as he felt himself to be, when he " reigned Lord High Admiral of the Delaware." He had in the very character of the men who gave him their patronage, a basis for all the material aid he required: they were anxious to furnish the means, but they wanted the assurance that they would not be spent in vain. Fitch was not the man to give them this assurance. As it was, however, the honesthearted fellow labored not in vain; he accomplished more in driving his boat, crude as it was, than had ever been done before; but he fell far short of introducing to the world a practicable mode of navigation by steam. This man of genius and misfortune, after spending some years in poverty and distress, took up his residence at Bardstown, Kentucky, where by his own hand he flung off this mortal coil, - closing a life of perseverance, intermixed with bitter disappointment and trouble. Before his death he made the request, " that he should be buried on the banks of the Ohio, that he might repose where the song of the boatman would enliven the stillness of his resting-place, and the music of the steam-engine soothe his spirit." 1 Truly prophetic words! 1 Hows' History of Virginia. CHAPTER VI. IT has been noticed that Read as early as 1788, while a resident of Salem, devoted himself to the purpose of applying steam-power to navigation and land transport. Having learned the unsuccessful attempts made by Rumsey upon the. Potomac, and Fitch upon the Delaware in 1787, and believing that their failure was owing to their ill-constructed machinery, and modes of propulsion, he sought to overcome the difficulty, by the invention and combination of machinery of a different and more perfect kind. He believed this could be done by so modifying Watt's improved engine as to fit it for a portable as well as stationary power. It had thus far been used in mills or fixed localities, where it was expected to remain, and it had been invented for no other purpose. Thus its heft and bulk hardly came into account in its construction. Indeed, power and durability were the great objects, without regard to size or weight in the stationary engines; but not so in an engine to be used in a boat or land carriage. In both of these cases they must not only be of small size, but light, and so light as to be carried in the craft or carriage they propel, not only with convenience and ease, but with economy and profit. In short, the engine must be of small size, comparatively light, without any loss of power, and work with freedom and safety. He believed, NATHANV READ AND THE STEAM-ENGINE. 47 moreover, that the modes of propulsion used by Rumsey and Fitch - setting-poles, oars, paddles, or the ejection of water from the stern of the boat — were not only awkward in their operation but unreliable. His first and great purpose was to invent a new boiler, of such a character as to dispense with the massive, old-fashioned boilers, and thus reduce the engine several tons' weight. He succeeded in the invention of a boiler, of which he made draughts and constructed a model, differing entirely from any before known or in use, which, from its characteristic principles, he denominated the " Portable Furnace Boiler." To use his own words, " it occupied but little space, was light and strong, and so constructed as to require no other furnace than what itself constituted, and was designed both for boats and land carriages." This boiler was constructed of seventy-eight tubes, placed within it, and hence has been generally denominated the tubular, or more properly, the multi-tubular, boiler.' The model of this boiler is not to be found, and is supposed to have been consumed in 1836, when 1 The tubes were placed in a vertical position, as will be seen from the following plan and specification of it. In the use of the multi-tubular boiler placed in this position, the Encyclopcedia Biritannica (vol. xx. p. 651), revised and republished the present year, 1860, speaks as follows: - "The Americans have adopted a form of tubular boiler, in which the tubes are disposed vertically, the smoke and flame passing round the outside of the tubes, and the water being contained in the inside. These vertical-tube boilers are very effective in generating steam, and partly for this reason, that the flame reaches further amongst their tubes than in the case of a horizontal boiler, in consequence of the greater space outside the tubes in which the flame may develop itself. The importance of this, especially while using the flaming bituminous coal, is very great. The absorbent surface is greater, and the weight of water it is necessary to carry is much less." 48 NrNATHAN READ AND THE STEAM-ENGINE. the Patent Office was destroyed by fire. The following copies of the patent, specification, and drawings of the boiler will sufficiently describe its form and nature. The patent also includes an improvement of the steam cylinder and method of propelling boats by means of the chain-wheel, which I shall notice hereafter.1 "THE UNITED STATES " To all to whom these presents shall come " GREETING: "Whereas, Nathan Read, of Salem, in the State of Massachusetts, hath presented a petition to the Secretary of State, the Secretary of the Department of War, and the Attorney-General of the United States, alleging and suggesting that he hath discovered the following useful devices, not before known neither used; that is to say, an improvement of the boiler of the steam-engine, by constructing it in such a manner as to constitute of itself a complete furnace that more effectually prevents the loss of heat than any other furnace that is wholly or in part foreign to the boiler itself, - by reducing its size, and rendering it very portable, and at the same time increasing its force, by exposing within a small space a very large surface directly to the fire, and by connecting it with a reservoir in such a way as to be replenished with water with as much safety and convenience when on board a vessel in motion as at rest.

The boiler alone actually prepared the steam-engine for a utility that it never before possessed. It rendered it portable, and made it a practical agent for moving boats and land carriages. It is claimed by the friends of Judge Read, that this was the first multi-tubular boiler invented; and this was what the inventor himself claimed, as 52 NATHAN READ AND TE STEAM-ENGINE. will hereafter appear, and as shown not only by the foregoing patent which he received as the original inventor, but by the following extract of a letter by him to Mr. Jefferson, then Secretary of State, and by virtue of his office one of the Commissioners of Patents: - "SALEM, January 8th, 1791. " SI: -- I forwarded last week to Mr. Remsen 1 models of several machines, drafts and descriptions of which are inclosed. The model of the boiler which I have forwarded, is an improvement upon one of those I exhibited last winter. The model I refer to consists of several annular vessels placed one above another within the furnace, in such a manner as to expose a very large surface directly to the fire. For annular vessels, placed in a horizontal position, I have substituted circular tubes, placed in a vertical position 2 within the furnace, which is formed by the boiler itself in the same manner as the other was. In the last boiler, which is stronger, more simple and elegant in its construction, I have paid less regard to the evaporating surface than in either of the others — finding by experiment that the principle of evaporation suggested by your Excellency is perfectly just, when applied to close vessels. I am sensible that a pipe was several years since made use of by Mr. Rumsey for generating steam, and also perceive from the' Philosophical Transactions,' that a tube in the form of the worm of a still was used upwards of twenty years ago for the same purpose; but do not know that any other person but myself hath ever 1 Mr. Remsen was the Secretary of the Board of Commissioners. 2 In the Scientific American, vol. iii. No. 11, new series, p. 174, September 8, 1860, the editors say, " The reason why we prefer a boiler with vertical tubes, is owing to the favorable results which have been obtained with such a boiler on board the United States frigate San Jacinto in comparison with one having the old-fashioned tubes. We do not mean one that has the fire returned through the tubes; but water tubes, as explained in Isherwood's lEngineering Precedents." NATHAN READ AND THE STEAM-ENGINE. 53 constructed a tubular boiler, formed in such a manner as to constitute of itself a complete furnace. It is about three years since I first projected a boiler upon this plan. How far my improvements merit an exclusive privilege, the Honorable Board will judge. Should a Patent be granted, I suggest it may be delivered to Benjamin Goodhue, Esq., who will pay Mr. Remsen all charges that have arisen in consequence of my application. " I am, with the sincerest respect, "Your Excellency's most obedient servant, " NATHAN READ." In Woolhouse's edition of " Tredgold," vol. i. p. 413, he says: - " The introduction of tubes into the boiler, is one of the greatest improvements that has been made in the construction of locomotives, and was the cause of the superiority of the Rocket engine to those that competed with it, and to all the former engines. The Rocket engine made by Mr. R. Stephenson, which was the engine that gained the prize for the best locomotive, at the opening of the Liverpool and Manchester Railway, in 1829, was the first engine made with tubes in this country." And in a note on the same page he adds:'_ "It appears that the merit of the first invention of a boiler with tubes is due to a French engineer, M. Seguin, who had a patent for it in 1828; although the application of the principle in the Rocket engine was undoubtedly an independent invention." The above allusions to the invention of the "m rulti-tubular boiler " 2 were undoubtedly made without a knowledge of Read's invention and patent of it. 1 Woolhouse, vol. i. p. 413. 2 This is the proper name of the boiler. 54 NATHAN READ AND THE STEAiM-ENGINE. But by comparison the general principles of this and the boiler of the " Rocket " will be found to resemble each other sufficiently to be the result of one and the same invention; and Read's invention was more than forty years anterior to either Seguin's or Stephenson's experiments. The only perceptible difference lay in the fact, that this boiler of Read was intended to carry the water through the tubes and the fire through the cavities between them; while Stephenson's boiler carried the fire through the tubes and the water through the cavities —a change very simple and easily made, and no doubt an improvement for locomotive engines; and it will hereafter appear that Read proposed the same thing —in short that he invented the multitubular boiler, to be used in either form, i. e., one with the flame passing through the tubes, and the other with the water. To show the analogy between the boiler invented by Read and that used upon the " Rocket" at the celebrated trial at Rainhill, the following description of the boiler of the " Rocket " used on that occasion, prepared by that eminent engineer, Robert Stephenson (son of George Stephenson), who under the direction of his father built the " Rocket " and obtained the prize, may be regarded as the best evidence that can be obtained on the subject. He says:"At this stage of the locomotive engine, we have in the multi-tubular boiler the only important principle of construction introduced, in addition to those which my father had brought to bear at a very early age (between the years 1814 and 1821), on the Killingworth Colliery Railway.l In the 1 Stephenson built his first locomotive at Killingworth in 1814. " The NA THAN READ AND THE STEAM-ENGI~NE. 55'Rocket' engine the power of generating steam was prodigiously increased by the adoption of the multi-tubular boiler. Its efficiency was further augmented by narrowing the-orifice by which the waste steam escaped into the chimney; for by this means the velocity of the air in the chimney, or in other words the draught of the fire, was increased to an extent that far surpassed the expectations even of those who had been the authors of the combination. From the date of running the'Rocket' on the Liverpool and Manchester Railway, the locomotive engine has received many improvements in detail, and especially in accuracy of workmanship; but in no essential particular does the existing locomotive differ from that (the' Rocket') which obtained the prize in the celebrated competition at Rainhill. "In this instance, as in every other important step in science and art, various claimants have arisen for the merit of having suggested the multi-tubular boiler as a means of obtaining the necessary heating surface. Whatever may be the value of their respective claims, the public, useful, and extensive application of the invention must certainly date from the experiments made at Rainhill. M. Seguin, for whom engines had been made by my father some years previously, states that he patented a similar multi-tubular boiler in France, several years before.1 boiler was cylindrical, eight feet in length and thirty-four inches in diameter, with an internal flue-tube twenty inches wide passing through it. The engine had two vertical cylinders of eight inches and two feet stroke let into the boiler, working the propelling gear wi~th cross-heads and connecting rods." He used spur-wheels and had a chamber around the chimney to heat the water before it entered the boiler. His car-wheels were all of a smooth surface, which he found by experiment were sufficient for traction. Life of Stephenson, p. 90, post. 1 George Stephenson sent two engines to France in 1828 for the St. Etienne Railway constructed in his usual form. Seguin took out Stephenson's boilers, and applied others with the flame passing through the tubes, which greatly increased the power of the engines. This gave Stephenson the idea of that form of boiler, which he afterwards applied to the "Rocket." 56 NATHAN READ AND THE STEAM-ENGINE. "A still prior claim is made by Mr. Stevens of New York, who was all but the rival of Mr. Fulton in the introduction of steamboats on the American rivers. It is stated as early as 1807 he used the multi-tubular boiler. These claimants may all be entitled to great and independent merit; but certain it is that the perfect establishment of the success of the multi-tubular boiler is more immediately due to the suggestion of Mr. Henry Booth, and to my father's practical knowledge in carrying it out.' "The boiler of the' Rocket' was cylindrical with flat ends, six feet in length and three feet four inches in diameter. The upper half of the boiler was used as a reservoir for the steam, the lower half being filled with water. Through the lower part, twenty-five copper tubes of three inches diameter extended, which were opened to the fire-box at one end, and to the chimney at the other. The fire-box or furnace, two feet wide and three feet high, was attached immediately behind the boiler, and was also surrounded with water. The cylinders were placed on each side of the boiler, in an oblique position, one end being nearly level with the top of the boiler at its after end, and the other pointing towards the centre of the foremost or driving pair of wheels; with which the connection was directly made from the piston-rod to a pin on the outside of the wheel. The engine and water weighed four and a quarter tons, and was supported on four wheels not coupled. The tender was four wheeled, And from this circumstance its invention was imputed to Seguin. Life of Stephenson, p. 262. 1 Life of George Stephenson, by Smiles, p 263. Henry Booth, secretary of the Liverpool and Manchester Railway, proposed to Stephenson to apply the boiler of Seguin to the " Rocket " engine, and the multi-tubular boiler, as they called it, was thereupon adopted. Booth was interested with Stephenson in the construction of the "Rocket." ibid. NATHAN READ AND THE STEAM-ENGINE. 57 and similar in shape to a wagon; the foremost part holding the fuel and the hind part a water cask."1 The priority and rights of -the respective claimants to the invention of the multi-tubular boiler, will be more particularly noticed hereafter; for the present the reader is invited to compare the above description of the boiler of the " Rocket " with the specification and drawings of Read of his boiler, which he patented in 1791 (ante, p. 48); from which it will appear that the principles of their construction were essentially the same. In the mean time, to show the advantage of the multi-tubular boiler over every other mode proposed, we will here give a brief account of the trial at Rainhill of the several engines entered for the prize. The prize offered by the Liverpool and Manchester Railway Company was ~500 to the most successful locomotive, the speed not to average less than ten miles an hour, the engine to consume its own smoke, not to be of more than six tons weight, and be able to draw twenty tons day by day; the boiler to have two safety-valves, one out of the control of the engineer; the engine and boiler to be supported on springs, the engines to be at the Liverpool end of the line ready for trial on the 1st of October, 1829. Each engine was to run two miles (the track being level), and make twenty trips in a day, and each to run on different days. The engines entered were as follows: the "Novelty," constructed by Messrs. Braithwaite & Ericsson; the " Sans-pariel," by Timothy Harkworths; the " Rocket," by Messrs. Stephenson & Booth; the "Perseverance," by Mr. Burstalls.2 1 Life of Stephenson, p. 265. 2 Ibid. pp. 266, 267. 58 NA THAN READ AND THEf STEAM-ENGINE. Stephenson was the first ready and the first to open the course; which, however, was not until the 6th of October. On that day the multitude assembled to witness the strength and speed of the young giants; a scene of intense curiosity, and of far greater interest in the view of all intelligent people, than any exhibition of the mechanic arts which had appeared before the world since the successful opening of steam navigation upon the Hudson. It was not a test of speed resulting from the mechanism of nature, like the tension and force of the muscle and bone and sinew of the horse, but from a force the work of human hands, and owing its creation and existence to human contrivance. A stud of animals about to exhibit their speed upon the race-course would excite but little interest, but for machines constructed by mortal artisans, self-moving and put in motion by fire and water, to enter the race, to speed their way through smoke and flame, upon limbs and joints of steel, was a novel affair. The interest produced by the occasion, most surely, was not greater than the result of the experiment foreboded; a decision was to be made whether the anticipations in this behalf, of men of science and genius, were to triumph, or whether all their deductions and labors were to end in a capital failure, and the actors irretrievably set down as a knot of visionary, delusive men. Moreover, whether the vast ends of trade and commerce and public travel, of the speedy centralization of distant lands and communities into one people and one social position, one neighborhood, one knowledge, one faith, who before knew not each other, were to be realized, or, on the other hand, whether all these high NATHAN READ AND THE S TEAM-ENGINE. 59 hopes were to be given up as impossible, and lost forever? It is hardly necessary to add that all the country around, its commonalty, beauty, and fashion, men of learning, nobility, and most eminent engineers and inventors, one and all, with their hopes and fears, stood by to witness the novel exhibition. What had been practically accomplished by Stephenson in the collieries at Killingworth, and upon the Stockton and Darlington Railway, which he had previously constructed with a degree of success far beyond the expectations of his employers, had partially opened the eyes of the public, and the world of gazers now looked upon the subject, not as a positive delusion of some cracked brain, but with a timid yet wavering sort of faith that seemed hardly to know what it was about, or how to believe its own eyes. The "Rocket" made its first trial by running six times back and forth over the two-mile track; and it performed this run, being twelve miles, in fifty-three minutes. It then gave the track to the "Novelty," which was next called out; and on this first day it ran at the rate of twenty-four miles per hour, nearly doubling the speed of the " Rocket." The "Novelty" had a bellows attached to its engine to produce combustion, and used an engine and boiler of the ordinary form as constructed by Boulton & Watt. The " Sans-pariel " was next called out, but the day was so far spent that it did not enter upon the track until the next day, when its boiler became defective, and it withdrew from the contest to make amends. On the second day, the bellows of the " Novelty " also gave 60 NATHAN READ AiYD THE STEAM-ENGINE. out, and it hahuled off for repairs. The boiler of the " Sans-pariel " was like that of the "' Novelty," but it used the steam-blast instead of a bellows to produce combustion. The "Perseverance" came upon the track, but was not able to go beyond six miles per hour, and was withdrawn from the contest. On this day, the " Rocket " was again put to the test. Stephenson hitched an omnibus to it containing thirty persons, and ran with his car-load of passengers at the rate of twenty-four to thirty miles per hour.' The third day, the " Rocket " ran, as its maximum speed, twenty-nine miles per hour, with about thirteen tons' weight attached to the engine, — its speed exceeding so far any previous calculation on the subject, and being so far beyond anything the eyes of the world had ever before seen passing in tractile force before them, that it made the exhibition a matter of wonder and astonishment, as well as enthusiastic admiration. The fourth day, the " Novelty " again appeared upon the track. It passed down well, and indicated a close run with the " Rocket "; but on its return the pipe of its forcing-pump burst, and it was again withdrawn for repairs. It was afterwards placed upon the track, and pressed to its maximum speed; but did not exceed from twenty-four to twenty-eight miles per hour.2 On the 13th, the " Sans-pariel," having been placed in repair, once more took the course, oiled up its joints, and fed its fires for a more hopeful showing. It passed up and down the track, but was not able to exceed fourteen miles per hour on the average. At length its pump got out of order, and it was obliged to stop 1 Life of Stephenson, p. 268. 2 Ibid, p. 269. NATHAN READ AND THE STEAM-ENGINE. 61 and give up the controversy. The next day, the "' Novelty " made another attempt to run; but it broke down, and gave up any further trial. The " Rocket," having in all respects fulfilled, and, indeed, far surpassed the conditions stipulated in the promised reward, received the prize; and after the award Stephenson, with a view to test the actual speed of the' Rocket," and show that he had not yet done what he might do, again put it on the course, disencumbered of any load. To the astonishment of all beholders, he now ran, without accident or delay, at the rate of thirtyfive miles per hour; and he publicly declared that a mile a minute, with proper improvements upon the engine, was attainable. It was now, to use the words of Mr. Smiles, that both " foul weather and fair weather friends " joined in eulogizing Stephenson for his success —a success attained by the adoption of the multi-tubular boiler.1 It is proper here to notice, that the "6 Rocket " alone on this occasion, used the multi-tubular boiler. The boilers of the " Novelty " and " Sans-pariel" were both of the same construction, and were of two tubes, or flues, in the form of the letter U, and presented a far less amount of heating surface than that of the "Rocket," which, with the steam-blast, gave to the "Rocket" its superior capacity and advantage, and secured to it the prize.2 Mr. Smiles, in his "Life of George Stephenson," remarks on this subject: - 1 Life of Stephenson, p. 271. 2 The steam-blast was produced by conducting the waste steam by a pipe into the chimney, thus increasing the draught and effecting a more intense combustion in the furnace. It was supposed that the power of the engine would diminish as the velocity increased; but Stephenson maintained and 62 VNATHAN READ AND THE STEAM-ENGINE. " It was the simple but admirable contrivance of the steam, blast, and its combination with the multi-tubular boiler, with its large heating surface, that at once gave the high-pressure locomotive its vigorous life, and secured the triumph of the railway system. As has been well observed, this wonderful ability to increase and multiply its powers of performance with the emergency that demands them, has made this giant engine the noblest creation of human wit — the very lion among machines." I Smiles does not attribute the invention of the multitubular boiler to Stephenson, but concedes that it was invented by some one else.2 He seems to have had no other information respecting it than the account of Seguin's experiment, to whom, from the simple fact that he was known to use it, he would accede the invention, but without any definite knowledge that he (Seguin) was in truth the. actual inventor. It does not appear that Seguin claimed the invention, — he gave Stephenson no such information - although he took out a patent for it in France, which he had the right to do, and applied it to Stephenson's engines, on the St. Etienne Railway. It is certainly a most remarkable fact, in its relations to the history of that invention, that none of our writers have hitherto been able to put their finger upon the man whom they presumed to say was the actual inventor. It is barely mentioned by some American authors, and referred proved by experiment that the reverse was the fact - that the more rapid the motion of the engine, the more intense was the combustion. The current of air produced and drawn through the tubes by the current of steam through the chimney (the steam-blast) more than doubled the power of the engine. 1 Life of Stephenson, p. 288. 2 Ibid. p. 261. NATHAN READ AND THE STEAM-ENGINE. 63 to by writers abroad, that Stevens of New York was supposed to be the inventor; but no writer has ever given any facts to support such an assumption. And as the matter now stands before the world, the invention, from the above mere assumptions, without any evidence of that positive kind which the case demands, and which from its very nature it is susceptible of furnishing, is carelessly attributed to Stevens or Seguin — to the former because some one said he claimed it, and to the latter because he used it. By a reference to Read's patent, specification, and drawings, the evidence becomes written and positive, instead of circumstantial and presumptive. The absurdity of Stevens's claims to this invention will more particularly appear when we come to consider the nature of his application to the New York Legislature and the Commissioners of Patents, in his controversy with Rumsey & Fitch. And how it probably came to Seguin's knowledge, will also appear hereafter. CHAPTER VII. THE boiler of Read was constructed with special reference to boats and land carriages, and was placed in a vertical position for both; and, as appears from the foregoing notel from the'" Encyclopaedia Britannica," it is a mode very effective, and coming more into use, and may be applied to locomotives as well as boats. The boiler of the locomotive engine, however, has for the most part been used in a horizontal position, with the flame instead of the water passing through the tubes. But the mode of using these boilers, whether vertical or horizontal, is regulated by utility or convenience, as the builder may decide for himself, and is not regarded as any part of the invention. Indeed they may be used in any position, and with the water or flame passing through the tubes at pleasure. The length and size of the boiler, moreover, is no part of the invention, as it is designed to be longer or shorter, and of greater or less diameter, according to the position in which you intend to place it, and the amount of work you aim to have it perform. So, too, the number of tubes that pass through the boiler is not specifically fixed, but may be more or less as desired. Read's boiler, as appears from the plan (see Plate I., Fig. 4), had seventy-eight. The "Rocket" had but twenty-four, and Stephenson's first locomotive on the 1 See p. 47. NATHAN READ AND THE STEAM-ENGINE. 65 London and Birmingham Railway, a hundred and twenty-four;1 and at this day, usually, many more than that are used.2 The size of the tubes was smaller than those in the "Rocket" (these last being three inches), and larger than those generally used at this day, the inner diameter being, ordinarily, about one and seven-eighths inches, the diameter of the tubes depending, in a great measure, upon the number used and the size of the boiler. It will be seen by the plate (Fig. 2) that the tubes were straight, and fitted into the tube-plates in the same manner as in the "Rocket,"3 and open at each end, except the short ones over the fire-grate, which were closed at the lower end. That there was also a method of heating the water before it passed into the boiler, - an idea carried out in the boiler of the " Rocket," but in a somewhat different form; the one by conducting the steam-pipe and funnel through the reservoir, and the -other by conducting the water along the side of the fire chamber, or box. The boiler was cylindrical in its form, as now used, being the best form for strength; and it had an external and internal cylinder, the latter forming the external part of the furnace, heating, in addition to the tubes, a large surface of water contained between the two cylinders. It was also furnished with pipes to replenish the boiler, and conduct the steam to the cylinder, with suitable cocks and valves to regulate them, and a safety-valve; and the boiler to be made 1 Woolhouse, vol. i. pp. 412, 413. 2 Of the main boilers of the Great Eastern Steamship, ten in all, four have four hundred tubes, and six have four hundred and twenty each, three inches in diameter. 8 Woolhouse, vol. i. p. 412, plate xce. 4 ibid, p. 126. 5 66 NATHAN READ AND THE STEAM-ENGINE. of copper or iron, and all its parts properly brazed or riveted together. Indeed, it will readily be seen, that by placing Read's boiler in a horizontal position, and conducting the fire through the tubes instead of the small apartments between them, with suitable arrangements to conform to this change, it will in every aspect of it be the same thing as that used in the "Rocket." George Stephenson, the father of Robert, commenced his railroad experiments as early as 1814, and from that time up to 1829, fifteen years, he was unable to run his locomotive beyond seven or eight miles an hour. But in 1829, after introducing the multi-tubular boiler, and the steam-blast, as before noted, he at once increased its speed to thirty-five miles per hour; I and by one slight improvement after another, mostly in the workmanship of the machinery, he afterwards brought it up to a maximum speed of sixty miles per hour.2 The steam-blast, and application of the multi-tubular boiler, are also spoken of "as the two grand inventions of Stephenson's life; and as forming the very soul of the locomotive." s In Smiles's " Life of Stephenson,"- page five of the preface, -he remarks, " The invention of the locomotive engine and its application to the working of railways, is one of the most remarkable events of the present century." And he proceeds to consider, "What manner of men were they by whom this great work was accomplished? How did the conception first 1 Smiles's Life of George Stephenson, p. 285. 2 Westminster Review, July, 1857, p. 128. 3 Ibid. NATHAN READ AND THE STEAM-ENGINE. 67 dawn upon their minds? By what means did railways grow and quicken into such vigorous life? By what moral and material agencies did the inventors and founders of the system work out the ideas whose results have been so prodigious? " In this excellent work, however, the subject of this memoir finds no place. His great labors upon the steam-engine to prepare it for locomotion, which in point of fact opened the way for Stephenson's subsequent success and triumph, were not known to this apparently impartial author. Had he before him the evidences of Read's inventions and improvements, no doubt he would have given him his proper place in his history of railroad invention; and awarded to him his just claims for the early part he took in working out " the ideas whose results have been so prodigious." And although the distinguished author wrote as a true and loyal subject of a foreign country, there is no reason for imputing to him any wish or desire to conceal the labors or genius of American inventors, - in this respect he seems to take a position far above the fretful prejudice of other English writers on the subject. He does not claim for Stephenson that he was the inventor of the multi-tubular boiler; but on the other hand, frankly admits that he was not; and speaks of Seguin's experiments with it as the first within his knowledge, yet does not claim to assert that Seguin was the inventor of it. CHAPTER VIII. IT may not be improper here to illustrate the subject, to give some account of the progress of railroad invention, which, like the steam-engine and steamboat, was effected by a succession of inventions and improvements to cheapen labor, and meet the everextending demands of trade and commerce. The first account we have of any attempt towards a railway-track, was made by Master Beaumont, who, as early as 1630, laid down wooden rails to haul his coal from near Newcastle-upon-Tyne to the river. The rails were laid in the ground for the wagon-wheels to run on, and thus overcome the friction produced by the yielding surface of common roads. By the embedding of plank or rails, it was found that one horse would draw a loaded wagon ordinarily requiring two; and that the expense of transporting the coal for shipment was thereby reduced about one half. These were used some forty or fifty years, before the idea of laying parallel rails was entertained; when, in 1676, a track was laid with parallel rails, and the wagon wheels so fitted as to be guided by and run upon them.l These roads were in use a hundred years or more, without any essential improvement; were run in the same old way, and were, for aught that appears, confined to the hauling of coal on the banks of the Tyne. -The 1 Life of George Stephenson, p. 68. NATHAN READ AND THE STEAM-ENGINE. 69 coal was transported from the mines, a distance varying from three to ten miles. In 1791, one Benjamin Outram made an improvement upon these roads, by making the upper surface of the wooden rails convex, and applying cast-iron wheels with a concave periphery, so that the wheel and rail closely fitted each other. These roads were called Outram roads, and afterwards, by a contraction of the name, 1" tram-roads." 1 Before this, as early as 1738, iron rails were used at Whitehaven. We find them also in Scotland, in 1767. In 1776 we have an account that the Duke of Norfolk laid iron rails upon cross timbers, and spiked them to the timbers, for the use of his colliery at Sheffield; and in 1789, one William Jessup built a railway in Leicestershire and used cast-iron edged rails, with flanges upon the tire of his wagons.2 In 1800, Benjamin Outram used stone in lieu of timbers for supporting his rails; but experience has shown that stone, from its nonelastic character, is not so suitable for cross-ties as timber. It will be noticed that these "tram-roads" were entirely worked by horses.; and various schemes were proposed, meanwhile, by these projectors to save the expense if possible of horse-power. One genius proposed sails as the cheapest and best way of running the " tram-roads; " but he found his motive power so unsteady and fluctuating, that he abandoned the idea of its utility. Steam-power seemed to them, after all, to be the only thing that could be successfully employed 1 Westminster Review, July, 1857, p. 121. 2 Life of Stephenson, p. 70. 70 NATHAN READ AND THE STEAMI-ENGINE. as a substitute for animal power. Much speculation had been indulged in by one and another, as to what steam might do if applied to land carriages; but no one could contrive any mode of making the application. The notions of men differed essentially on the subject, and each one who took the matter into thought seemed to have a theory of his own. One Chapman tried an experiment, by stretching a chain from one end to the other along the centre of his track, with the chain passingonce round a grooved barrel wheel, which turned under the centre of the engine, and as the wheel turned the engine moved along slowly;' but this proved a tiresome and profitless business. Another man of the name of Bronton, of Derbyshire, rendered himself famous by the invention of what he called his "Mechanical Traveller," for which he took out a patent. It was constructed to travel upon legs, " working alternately like those of a horse." But it blew up in one of his experiments, and killed several persons, and thus the anticipations of the inventor were brought to a sudden close.2 It was not discovered until 1813 (then by Mr. Blockett), that smooth wheels would adhere sufficiently to the rails, to draw any number of wagons attached behind; and the absurd idea, that the wheels must be cogged or toothed, was exploded.8 Before this a track containing four rails was used; two for a set of cogwheels running on the outside, and two for a set of smooth wheels on the inside, to sustain the weight I Life of Stephenson, p. 81. 2 Lardner On the Steam-engine, 7th edition, p. 338. 8 Life of Stephenson, p. 85. NATHAN READ AND THE STEAM-ENGINE. 71 of the load. Stationary engines were proposed and strongly advocated for the transportation of coal and other heavy loads on " tram " ways; but this was found more expensive than horse-power, and given up. Indeed, so strongly was the prejudice fixed in favor of the great utility of c" tram-roads " worked by horses, that but few persons could persuade themselves that steam could be used with as much economy or profit as horse-power. Even Tredgold, that distinguished railroad engineer, then supported the opinion that locomotives could not be driven so fast as horses, and that stationary engines, if any were used, would be most economical and safest - and, moreover, that any velocity beyond ten miles per hour, could in no case be expected.' Previous to 1829 no locomotive had exceeded six or eight miles per hour.2 Even the Killingworth railway, which Stephenson first constructed (in 1814), using the ordinary steam-engine, worked but four miles per hour, and was the most successful of any then constructed; yet it worked clumsily, and was found not to be so economical as horse-power. The prejudice against railways, in the mean time, on account of the competition they created with the laboring classes, was very great; and tended to check improvement in the system. Even up to the time of constructing the Liverpool and M/ianchester Railway, it met with such opposition on the line of it, among the people, that 1 Tredgold On Railroads, 2d edition, p. 119. 2 The Stockton and Darlington Railroad, constructed by George Stephenson, was opened on the 27th of September, 1825; and was the first rail-;road ever opened for freight and passengers; yet the speed of the engines did not exceed six miles per hour; - a speed that passengers of the present day would hardly have the patience to endure. 72 NATRAN READ AND THE STEAMf-ENGINE. they drove off the surveyors with guns, and pitchforks, and other deadly weapons; pelted them with stones and missiles, and insulted them in all manner of ways.1 Meanwhile political economists were divided on the subject of their utility; some strongly advocatingthe cause of the laboring classes, and supporting them in their ill-founded belief, that their work,. and with it their bread, was in danger of being taken from them. But no human effort can check the progress of art, any more than it can check the progress of freedom. Both will work their way in spite of opposition, and achieve new triumphs, to a more glorious consummation in the future. Step by step this great work went on, and various were the experiments to construct a railroad track and car in such a way as to adapt them to the old steam-engine of Watt, which engine they seemed to look upon as a fixed thing, admitting of no alteration or improvement. Thus, in the words of the venerable Dr. Cotton, " they sought to fashioneth the house to the hangings, instead of the hangings to the house." Not so with Read. His great purpose had been to reconstruct the steam-engine, knowing that it could not be successfully applied to locomotion, without very extensive modifications; in short, he had labored to " fashioneth his hangings to his house." To this end, he had invented the multi-tubular boiler, as a substitute for the old one; had dispensed with the condenser; and by his own calculation, which seems not to have entered before into the mind of any one, he applied the steam force of two atmospheres, instead of 1 Life of Stephenson, p. 168. NATHAN READ AND THE STEAM~-ENGINE. 73 one, to his piston, and thus converted the condensing engine of Watt into a complete working portable highpressure engine, — the only engine that can be properly used on railways. The steam-engine, thus modified by him, reached the point of being light and portable. It not only dispensed with the weight of the condenser,1 but of the water to be used to produce condensation, - the air-pump, working-beam, and other portions of the machinery, as well as the brick work and extra weight of the boilers of the old stationary engines. This was twelve years before the steam-engine was known to be used in the form of a high-pressure engine; and the invention actually produced that change in the use of steam as a locomotive power, that it remained only to be applied, to open that railroad system which has since assumed such vast proportions. Read, though the inventor in 1788, and patentee in 1791, of this high-pressure portable engine, never himself succeeded in securing the necessary means to apply it to practical use; but that part of the work, in obedience to a stern necessity, he was obliged to leave to others to accomplish; and it has been applied by one and another, until it has become the chief motive power, not only for land transport, but for inland navigation to a very great extent, wherever industrial labor, commerce, and civilization have found their way. 1 Leopold, a German, gave an account, in 1718, of two engines, the invention of which he imputed to Papin. One was like the engine of Savary, the other was an engine in which steam, by means of a four-way cock, and two cylinders and pistons, without the aid of the atmosphere, was made to work the engine without condensation; but it does not appear.that any very definite notion was entertained as to the tension of steam:equired to work it. 74 NATHAN READ AND THE STEAM-ENGINE. Oliver Evans, in 1801, was the first person known to introduce high-pressure steam to practical use, which he applied for grinding plaster and sawing marble, in Philadelphia. Trevethick & Vivian were the next, in 1802, who are known to have used an engine of similar constructions which was many years after Read's invention.2 Neither Evans or Trevethick & Vivian, however, introduced the multi-tubular boiler, but each used a boiler with a single cylinder, with the fire made within it. s" Richard Trevethick, a captain in a Cornish tin-mine, and a pupil of William Murdock, determined to build a steamcarriage, adapted for use on common roads. He took out a patent in 1802, and Andrew Vivian, his cousin, joined him in his patent, Vivian finding the money, and Trevethick the brains. The steam-carriage built by Trevethick presented the appearance of an ordinary stage-coach on four wheels. It had one horizontal cylinder, which, together with the boiler and furnace-box, was placed in the rear of the hind axle, and the motion of the piston was transmitted to a separate crank-axle, from which, through the medium of a spur gear, the axle of the driving wheel (which was mounted with a fly-wheel) derived its motion. It is also worthy of note, that the steam-cocks and the forcing-pump, as also a bellows, which he used for quickening combustion in the furnace, were worked off the same crank-axle; and that the piston was not only raised but depressed by the 1 Woolhouse, vol. i. pp. 41, 141; Rep. of Arts, vol. iv. p. 241, New Series; Renwick On the Steam-engine, p. 254, post. 2 " High-pressure engines usually work with a tension of five to six atmospheres; and may, with proper construction and care, be used with equal safety, as condensing engines; and are far more economical, where the saving of weight, room, and cost is an olject; as in case of locomotives, and boats for river navigation." -Renwick, pp. 180, 183. NA THAN READ AND THE STEAM-ENGINE. 75 action of the steam, being in this respect (erroneously says Mlr. Smiles)'an entirely original invention, and of great merit.' This was the first locomotive put into practice. Trevethick & Vivian determined to exhibit their machine in the capital. They set out with the locomotive from near Land's-End, where it was built, for Plymouth, to be conveyed from thence to London on a vessel. Coleridge relates, that while the vehicle was on the way to Plymouth at the top of its speed, it tore away a gentleman's garden fence; and on approaching a toll-gate Vivian called out to Trevethick to slacken speed. He immediately shut off the steam; but the momentum was so great that the carriage came dead upon the right side of the gate, which was quickly opened by the toll-keeper.'What have we got to pay here,' asked Vivian? The poor toll-man, trembling in every limb, and teeth chattering, essayed a reply.' Na, na, na, na'- -' What have we got to pay, I say?'' Na - nothing to pay! My de- dear Mr. Devil, do drive on as fast as you can, - nothing to pay.' The carriage safely reached London and was there exhibited; and it dragged behind it a wheel carriage filled with passengers. It was impossible from the badness of English roads to introduce it into practical use; and after exhibiting it as a curiosity, it was abandoned by Trevethick as a practical failure." 1 In 1804 Trevethick & Vivian constructed a locomotive, to run on tram-ways, for mining purposes. The first trial it dragged several wagons, carrying about ten tons of iron, five miles per hour.'" Yet it proved like the first steam-carriage, a practical failure. It was never employed to do regular work, but was abandoned after a few experiments, as the rails were:little calculated to sustain so heavy a weight; and the 1 Life of Stephenson, pp. 76, 77, 78. 76 NATHAN READ AND THE S TEAJM-ENAGINE. engine was taken from the wheels and put to work at one of the pumps in the mine.1 The periphery of the wheels of Trevethick & Vivian's locomotive was made rough by bolt-heads, to keep the wheels from slipping; and afterwards in 1811, racked or toothed wheels and rails were used for the same purpose, by Blenkinsop of Leeds, who for several years transported coal with them from Middletown to Leeds, a distance of three and a half miles, dragging some thirty coal cars, at a speed of three or four miles per hour. These were really the first earnest working experiments of the locomotive used and continued for practical purposes. These engines were worked with two cylinders.2 The boiler of the above locomotive of Trevethick & Vivian, was of cast iron, and unsafe; and although it contained but one tube, yet it was in the form of the letter U, passing in a curve through the boiler with one end used for a grate and furnace, and the other connected with the smoke-pipe, to emit the smoke and heated air. The engine had no condenser, and was worked by high-pressure steam; and was used on a tram-road at Merthyr Tydvil in South Wales, to transport heavy materials in mining operations.3 The same year, 1804, that Trevethick & Vivian tried their engine, Oliver Evans also put an engine of the high1 Life of Stephenson, p. 79. 2 bicl. p. 80. 3 Cyclopeica of Useful Arts, p. 324. Mr. Trevethick, in his evidence before a Committee of Parliament in 1831, testified, " that his MIerthyr Tydvil engine was a detached ingine, independent of all fixtures, without condensing water, and the fire enclosed in a boiler surrounded by water, and sa forced draught to prevent a high chimney; it was independent from brickwork, light, safe from fire, and occupying but little room." NATHAN READ AND THE STEAMI-ENGINE. 77 pressure principle into his dredging-machine at Philadelphia.1 The engine of Evans, however, retained the working-beam, which may be regarded as an advantage in propelling boats, but could not be used in locomotives. It is stated by Professor Renwick, in his treatise upon the steam-engine, " Not the least of the improvements of Evans lies in the form of his boilers, which he was the first to make in the form of a cylinder, -a form preferable to any other yet proposed." 2 As already seen, the boiler invented by Read was in the form of a cylinder, and designed for strength, as well as occupying but little space. By returning to Judge Read's letter to Mr. Jefferson of the date of January 8, 1791, it will be noticed, that he speaks of two models of boilers he had exhibited to the Commissioners the winter previous; but which he withdrew, and substituted therefor the one on which he received his patent. A sketch of one of the boilers withdrawn is found among his papers, which will show that he, as appears by this drawing and description of it, constructed the model of a boiler, in which the flame and heated air passed through the tubes, and consumed the smoke. A copy of the drawing, and short memoranda upon the same paper, is all that remains of his account of this invention. The paper is filed in his own handwriting, " Steam Boiler 1790," and under the drawing is written, in his handwriting lso, - "Section of a steam-boiler which exposes a large surface; is fbed from the top through the large tube a, and the hot 1 Miiller's Physics, p. 517.

B. - The boiler constitutes the whole furnace, except the brick work at the bottom; and it consumes the smoke -- o o, float." This seems to establish the fact that he invented a tubular boiler of each kind: one with the water passing through the tubes, and the other with the flame consuming the smoke. As seen from the plan, this boiler also was cylindrical. His mode of feeding the furnace with fuel down the large pipe a, is a matter for the curious; this large tube a, added much to the amount of surface exposed, and served as a part of the fire chamber of the furnace; when closed at the top, as was doubtless proposed, it would cause the flame and heated air to pass through the tubes; and his arrangement under the base of the tube a, or firechamber, to sustain the fuel by a thick plate of iron, with open grates at each end to admit a current of air, would produce a strong draught through the small tubes, and increase the flame; while the float o o would not only indicate the height of the water in the boiler, but work a valve in the pipe that replenished the boiler with water from the reservoir. The water in the reservoir would also be heated before entering the boiler, by the smoke-pipes, and a section of the fire chamber passing through it. As the plan does not exhibit any other part of the machinery, it does not show his mode of conducting the steam to the cylinder and working the engine; which doubtless was designed in the ordinary form. We will now proceed to notice improvements upon the steam-cylinder. PLATE 3 F 1iD Fig. 6 Fi 3 c:ct CC CHAPTER IX. HIs improvement upon the steam-cylinder, contained in his patent, will fully appear from the following draught and specification of it, filed with the Commissioner of Patents: " Specification of an Improved Steam Cylinder, advantageously constructed to work in an horizontal position. PLATE III. " Figure 3 is a perspective view of the cylinder and working frame.

These are alternately opened and shut by the pins e fg h i k, in the working frame.

B of the cylinder. Meanwhile the pin h closes the regulator c, and the pin f opens the regulator b, and the steam will pass from the end B to the condenser, while the end A will be replenished from the boiler; in consequence of which the piston will move from A towards B, and the pins of the working fiame will open the regulators that were closed, and shut those that were before opened; then the end A of the cylinder will be exhausted, and the end B replenished with steam, and the piston will move back with equal force, and the whole operation be again repeated. NOTE, - Slidingplates or regulators, like those made use of for other engines for letting in and shutting off steam from the cylinder, may be substituted for the cocks or regulators a b c d." The above invention was expressly designed to adapt the steam-engine to land carriages. This was fifteen years before Evans and Trevethick & Vivian tried their first experiments with the locomotive. And although the machinery will not compare in its style with the more elegant and finished machinery of the present day, yet proper allowance will be made for this, as it was the first essay, as is believed, to change the steamengine to the great purpose of locomotion. Notwithstanding the simplicity of its construction, it embraced the principle, if it did not attain to the more elegant and complex mechanism of our present locomotive engines. The above cylinder so nearly resembles the cylinder of Trevethick & Vivian, which they first used, it would almost seem that theirs was constructed after Read's plan. The following description of their cyli.nder will be interesting to the curious on this point: - "The cylinder was placed upon its side, and in one posi. NAT-HAN READ AND THE STEAM-ENGINE. 81 tion of the cock a communication was opened between the boiler and one end of the cylinder, while another communication was opened between the other end of the cylinder and a tube leading to the chimney (or the condenser, as the case might be). Steam was thus admitted to act on one side of the piston, and allowed to escape from the other side to the chimney. When the piston attained the end of the stroke the position of the cock was reversed, and the steam, which had just driven the piston in one direction, was allowed to escape to the chimney, while steam from the boiler was admitted on the other side of the piston, to impel it in the contrary direction; and in this manner the piston was continually driven backward and forward, in a horizontal direction, and parallel to the direction of the load. The piston-rod was moved through a hole, corresponding with it in magnitude, in the cover of the cylinder, in which it was rendered steam-tight by a stuffing-box properly lubricated." 1 The above description of Trevethick & Vivian's cylinder is a good description of Read's, and indeed, nearly an exact one. It is certainly a matter of interest to know how it happened, that in the first locomotive ever put in operation, for which Trevethick & Vivian have the credit of the invention, the cylinder admits of the same description precisely as that of Read's, which he invented and patented fifteen years before. The following extract of a letter from Judge Read to the Hon. Timothy Pickering, will throw some further light on this subject: - " BELFAST, January 27, 1817. " Meon. TIMOTHY PICKERING. "SIR:.... On examining my papers at Belfast, 1 Vide Cyclopedia of the Useful Arts, p. 324. 6 82 NATHAN READ AND THE STEAM-ENGINE. I find that it is upwards of twenty-six years since I invented the steam-engine, with horizontal arms, similar in principle to the engine for which Mr.'Trevethick has recently received a patent in England. I have now in my possession a drawing of the engine, and an accurate description of its principles, construction, and operation, and of the manner of connecting it with the boiler, copied in the year 1789, from my original draught, by Mr. William Shepard Gray, the cashier of Essex Bank. "With assurances of my highest respect and esteem, " N. READ." The mere idea of applying steam to land carriages, as before stated, was not new. Watt and his journeyman, Murdock, entertained the idea, and, in short, tried to apply their condensing engine to a small model; but they wholly failed in the experiment; and Watt himself said that there was no use in attempting to apply it.1 And in a letter to Mr. Boulton, September 12, 1786, in referring to Murdock's speculations on the subject, he says: - "In the mean time, I wish William (meaning William Murdock) could be brought to do as we do, —to mind the business in hand, and let such as Symington and Sadlier throw away their time and money hunting shadows." 2 He regarded the thing as impracticable, from the great heft of the engine, unless it could be so modified as to make it portable.3 Read's improvements were designed to reduce the weight of the engine, and make it portable. Hence he styled it the " Portable Steamlengine." Watt did not seem to discover any mode 1 Muirhead's Life of Watt, p. 343, post. 2 ibid. p. 349. 8 Ibid. p. 340. NATHAN READ AND THE STEAM-ENGINE. 83 of doing it. He suggested the idea of applying a rotative reacting steam-wheel, of the form of Barker's centrifugal reacting water-wheel; but said of it, "This would not abridge the size of the boiler; and I am not sure that such engines are practicable." 1 Indeed, " the impossibility of using the condensing engine was ascer-. tained and admitted by Watt." 2 It is claimed for Oliver Evans that he was the first to apply the steam-engine to a locomotive. It will be remembered that his experiment was the same year as that of Trevethick & Vivian, - 1804. They were contemporaries in the construction of their locomotives; but which first " fired up " their engine does not appear, and is not very material for us to consider. Evans did not, however, construct his machine for running upon the land, but on the water; and only proposed to convey it to water from the place of building, - being about a mile and a half from the Schuylkill, at Philadelphia. His machine weighed about twenty-one tons, and he designed it for dredging merely. He put a steam-engine in it for the purpose of working it on the river, and at the same time availed himself of the power of his engine to convey the machine, or muldscow, to the river. To accomplish this purpose he placed wheels under it, and turned the wheels with the engine, which readily transported his dredge to the water.3 Trevethick & Vivian's machine was designed to run upon a railroad track, or tram-road, as then called, for the purpose of transportation upon the 1 Muirhead's Life of Watt p. 348. 2 Renwick, On the Steam-Engine, p. 297. 8 Lives of Eminent Mechanics, p. 76. 84 NATHAN READ AND THE STEAM-ENGINE. land. Hence to them is justly given the credit of running the first locomotive, properly so considered. Prof. Renwick states that " Evans was the first who entertained rational hopes of being able to move carriages by steam;" and "not only was the first to entertain correct views, but was also the first to submit them to practice in the removal of his dredging machine." 1 In view of what has been shown, these conclusions are erroneous in point of fact, and not warranted by any just interpretation of the case; which can be accounted for in no other way than that the professor had not then been informed of what others had done. In the first place, it is difficult to see why he should give the preference to Evans, who had constructed no locomotive with a view to its use upon the land; while Trevethick & Vivian had constructed theirs and applied it expressly for that use. In the second place, this experiment of Evans's was made fifteen years, as before noticed, after Read's invention of the high-pressure steam-engine, and his improvements to adapt it to land carriages, of which he constructed a model. Evans's engine, moreover, though acting upon the high-pressure principle, did not approach so near the locomotive-engine of the present day as Read's. Instead of the multi-tubular boiler, constructed with numerous small tubes passing through it, as now used, his boiler consisted of only one large tube, or flue, passing through its centre.2 He also retained the old Newcomen working-beam, with his cylinder standing in an upright or vertical position; while Read int):o1 Renwick's Treatise on the Steam-Engine, p. 297. 2 Miiller's Physics, p. 518. NATHAN READ AND THE STEAM-ENGINE. 85 duced the cross-head, and placed his cylinder in a horizontal position. This arrangement of machinery by Evans never has been used for locomotives, and in point of fact is wholly impracticable for such a purpose. Thus with an engine that never has or could be used with success, it must be regarded as a great stretch of credulity to believe that "Evans not only was the first to entertain correct views, but was also the first to submit them to practice." 1 Evans's experiment was but a rude invention to convey his scow to the river; yet, like many others before him, he doubtless had it in mind to show that he could move a machine upon the land, as well as upon the water, by the force of steam, - an idea he had long entertained, and for which hle had been much ridiculed. His machine was simply a large flat, or scow, and his engine of five horse-power, designed for raising the mud into the scow. He made wooden axle-trees of rough timber, of sufficient length for the scow to rest upon, and used wheels constructed like common cartwheels.2 He had a wheel inside the scow, which he turned with the engine, and this wheel gave motion to the wheels below, by means of a chain or rope that passed round the hub of this and one of the forward wheels, which was also connected with one of the hind wheels in a like manner.3 His load was a heavy one I The Encyclopcedia Britannica, vol. xx. p. 581, 1860, expresses similar views, taken, no doubt, from the above remarks of Prof. Renwick. It says, "T'o him (Evans) may be attributed the rapid advancement of America in all that relates to the introduction of the steam-engine, in its multifarious applications, and especially in steam navigation." These contagious opinions are apt to be worth but little. 2 Hows' Memnoirs of American Mechanics, p. 76. 3 Ibid. 86 NATHBAN READ AND THE STEAM-ENGINE. for his engine to move on a common road, and it progressed very slow; but he succeeded in conveying it to the river, where the scow was taken from the wheels and launched into the water. This was the only endeavor ever made by Evans to move a land carriage by steam. Evans, however, is entitled to great credit for his improvements upon the steam-engine; but they were many years subsequent to the inventions of Read, whose engine was not only the first, but a more perfect and complete development, of the high-pressure principle. The following is a copy of the plan and specification of the steam-carriage invented by Read, which he presented with his petition to Congress for a patent, in 1790: -- "PLATE V. " Fig. 1.

W IV, two cocks to shut off the communication of steam between the boiler and either or both of the cylinders, as circumstances may dictate. a a a a, eduction-pipes, with cocks alternately to convey off the steam from each end of the cylinder. The cylinders are worked without a condenser, by letting the steam vent itself against the atmosphere; in consequence of which it is necessary that the condensation of steam in the cylinders should be equal to the pressure of two atmospheres, in order to produce the same effect it would with a condenser when the condensation was equal to the pressure of one atmosphere. The ends of the short pipes a a a a are turned back, that the carriage may have an additional impulse forward. "The carriage may be turned either way with great facility, by means of the cocks W Wand the director L. To turn the carriage to the right, the right-hand cock W should be closed more or less, according to the shortness of the turning, which will check the operation of the right cylinder, and consequently retard the motion of the right wheel, and at the same time tend to accelerate the motion of the left wheel; which prepares the carriage to be turned with ease by moving the director to the left. After the carriage is turned, the steam-pipe should be opened as before. To turn the,carriage to the left, a contrary operation is necessary. When ~you want to stop the carriage, close the steam-pipes D D, by'turning the cocks V W; and the steam in the boiler will vent 88 NATHAN READ AND THE STEAM-ENG1NE. itself at the valve nigh the bottom of the boiler, without endangering the engine. " NOTE.- The whole of the machinery for moving and directing the steam-carriage, except the top of the boiler, the director, and two regulating cocks, are, for conveniency, placed under the body of the carriage. " NOTE. - The cylinders may be placed perpendicularly, and impel the carriage forward by means of clicks and movable pinions; but experience alone will determine the best method." This steam-carriage, simple in its construction, will, nevertheless, show important facts in relation to Read's improvements, at that early day, upon the steam-engine, to fit it for propelling land carriages. It shows that he proposed to place the cylinders in a horizontal position, and turn the wheels by applying the piston-rod directly to them, without a working-beam; that he dispensed with the condenser, and calculated that the density of steam in the cylinders, on that account, should be equal at least to the pressure of two atmospheres instead of one, —an important fact,, as before noticed.1 This, with the invention of the multi-tubular boiler to raise high steam, changed Watt's condensing into a highpressure engine complete in all its parts, and dispensed with a large share of the bulk and weight of the engine. Watt, Murdock, Symington', Sadlier, and others had speculated upon the same thing, without being able to make such a change in the steam-engine as to apply it to locomotion; and Watt, as before stated, admitted. that the condensing engine could not be used for suck a purpose.2 1 Ante, p. 72. 2 The following brief account of Murdock's experiment is quite amusing;: NATHAN READ AND THE STEAM-ENGINE. 89 Prior to 1790, when Read petitioned Congress1 to secure a patent for his invention of land carriages to be driven by steam, no successful application of steampower had ever been directed to such a purpose except to meet with insurmountable difficulties, and be rejected as a thing impracticable.2 The idea that it was capable of giving wings to the traveller, and transporting overland, as it now does, the commerce of nations, was at that time wholly new, and to the mass of mankind was looked upon as a matter equally mysterious and visionary. Even the members of Congress, the congregated assemblage of the wisdom and intelligence of the country, were so skeptical on the subject that when Read's petition for a patent for the application of steam to land carriages was read by the clerk of the House, a general smile was excited among the members, —a different look entirely from that now seen, in the earnest debates of Congress on the several projects for opening lines of railway to the Pacific. "Murdock constructed, in 1784, a diminutive steam locomotive, heated by a spirit lamp, which ran off from him, in a dark evening, down a lane, in Cornwall, where he was trying it, and was mistaken for the devil by the poor clergyman of the parish, who chanced to be returning home that way just as the fiery little object was in its mid-career." -Westminzster Review, No. 33, p. 121. 1 This was before the passage of the " Act to promote the Progress of the Useful Arts." 2 It is stated in the North American Review, July No., 1858, " that the first actual model of a locomotive of which there is any written account was made by a Frenchman named Cugnot, who exhibited it to the Marshal de Saxe in 1763. A second one, which he made for the king, is now preserved in the Conservatoire des Arts et Mdtiers. It was considered too dangerous a monster to be trusted, as when set in motion it rushed forward and knocked down a wall, after which it was shot up." This must have been tried by th( old Newcomen engine, probably, as none other is known to have then belen in existence. 90 NATHAN REA4D AND THE STEAM-ENGINE. The petitioner, who was present at the time his application was read by the clerk, felt stung by the indignity of the House, and he withdrew that part of his petition relating to land carriages. He did this after his papers came before the commissioners of patents, to whom the subject was referred by Congress, on the passage of the act organizing that board. After the withdrawal, the commissioners, through their secretary, Mr. Remsen, requested the renewal of his application for his land carriage; 1 but the manner of the reception of this part of his petition to Congress by that body, was a matter with him not easily overcome. He saw that the members looked upon the subject as visionary, which was quite too trying for his sensibility and better knowledge; and he did not renew this part of his petition, notwithstanding the request of the commissioners, whose duty it was to decide upon the merits of the application. He consequently took no patent for moving land carriages by steam.2 There does not however appear to be any knowledge or history before this, of any change of the old condensing engine of Watt, into the high-pressure engine that prepared the steam-engine for land carriages or locomotives. Can it be said, that Evans or any one else before this, invented or applied the multi-tubular boiler, the improved cylinder placed in a horizontal position, with the piston worked both ways by a steam force not less than two atmospheres, and with the crosshead and connecting rods, to a land carriage or locomotive? Did Watt discover this machinery, or Murdoc'k 1 See Mr. Remsen's Letter on p. 111. 2 See Appendix No. 3. NATHAN READ AND THE STEAM-ENGINE. 91 apply it to his fiery little devil? And the experiments of Evans, and Trevethick & Vivian, with the locomotive had yet many years to wait. In fact, the abovenamed inventions embrace the essential parts of the machinery of the locomotive engines now in use. CHAPTER X. HAVING said thus much in reference to the adaptation of Read's engine to land carriages, we will now return to the steamboat, and pursue his experiments in relation to that subject. After his improvements upon the steam-engine, he constructed a boat of sufficient size to carry a man, with the view of determining the best mode of propulsion. It appeared to him that paddlewheels were the most natural means, and by proper adjustment to the engine and boat would work with ease, and impart a greater and more steady propelling force to the boat than any other plan. These had never been tried in America nor in Europe, in the form he proposed to apply them. Perrier had utterly condemned them; and the experiments of Hull and Miller, as will be recollected, were upon different plans altogether; the former proposing but one wheel in the stern of the boat, and the latter using but one between the kelsons of his double craft. From the statement of Read,l it appears that none of the above experiments had come to his knowledge when he applied paddle-wheels to his boat. The silence of Dr. Franklin on the subject of paddle-wheels, while he proposed the plan of Bournelli for ejecting water from the stern of the boat, and the opinion expressed by the American.

N: ATHAN READ AND THE STEAM-ENGINE. 93 chusetts, that they believed Read the original inventor of paddle-wheels, as will appear hereafter, would seem to confirm the idea, that neither he nor they had a knowledge of those experiments. His boat was constructed in 1789; he attached the paddle-wheels to an axis extending across the gunwales of the boat, turned by a crank; and designed to be moved by his high-pressure engine, with the continuous rotative principle of Watt; which he (Watt) had invented and put in operation in factories some four or five years previous. Watt, as before noticed, had applied this motion to his steam-engine to make it available for turning the wheels of mills 1 and factories, without any thought or purpose of applying it to the wheels of a steamboat.2 By means of the crank worked by hand, Read propelled himself across an arm of the sea (called Porter's River) in Danvers; his boat went with great rapidity and worked to his entire satisfaction. He then satisfied himself by his experiment that paddle-wheels would drive a boat with great ease and speed, when turned by the power of the steamengine, and controlled by its steady rotative principle. He at once determined to use paddle-wheels as the mode of propelling his boat, and constructed the model of it accordingly with a view to a patent. Several gentlemen were present and saw the above experiment with the boat, among whom was Rev. John Prince, D. D., of Salem; as the following certificates of Dr. Prince and William Shepard Gray, in their own handwriting, among the papers left by Judge Stead, will more fully show. The paper is filed in 1 Ante. 2 Muirhead's Life of fWatt, p. 330. 94 NATHAN READ AND THE STEAM-ENGINE. the handwriting of Read, " Memorandum of William S. Gray and Rev. John Prince." The following is a copy: - "MEMO. - In the summer of 1788 I went to assist Mr. Nathan Read in keeping his apothecary shop; the following winter and in the summer of 1789, he was much engaged on mechanical and philosophical subjects; particularly in the construction of a steam-engine, whose power might be advantageously applied to the propelling of boats and carriages; and in order to ascertain by experiment the effect that floatwheels would have upon the boat, I very well remember that he had a light boat built by a Mr. Pierce, to which was attached a pair of float-wheels to be moved by hand - the experiment was tried in Porter's River in Danvers. I was not a witness to it, but was told that it succeeded to his fullest expectations. The boat was afterwards brought back and remained for some time in the back part of the shop; why steam was not applied I then did not make inquiries, and soon after leaving his shop for other pursuits, I made no further inquiries about it, but have since understood it was for the want of a sufficient capital to put it in operation.

"DEAR SIR: — Allow me to introduce to you my much esteemed friend, Nathan Read, Esquire, the ingenious inventor and improver of several useful machines, on account of which he is now on his way to Washington. "I believe you were engaged as counsel for your friend, Colonel Ogden, in relation to his controversy with the Fultonites, before the Legislature of New Jersey. At any rate, I presume you are acquainted with the merits of the case. Mr. Read was the real inventor of the essential part of Fulton's machinery-the water-wheels as applied to propel boats by steam. Of this he can produce satisfactory evidence, which he will show you if your leisure admits. "I pray that Mr. Read, as a gentleman of science and distinguished worth, may receive your attentions.

But what especially made me de 96 NA THAN READ AND THE STEAM-ENGINE. sirous of your seeing Mr. Read, was the recollection of your zealous patronage (I think I do not mistake) of Mr. Fitch, in his essays to propel boats by steam. Mr. Read will satisfy you that he was the real inventor of the grand and essential parts of Fulton's machinery, as applied to the moving of vessels - the water-wheels; and stated the same in his petition to Congress, in the year 1790, while sitting at New York, where it was publicly known, and where Fulton, I take it, aided by Chancellor Livingston, began his operations with those wheels. " With great respect and esteem, " I am your friend, "T. PICKERING." "MIERS FISHER, Esq." Read's experiment with paddle-wheels, taken in connection with his engine, as shown by his plans, drawings, and model which he had constructed, presented a new combination of machinery, which is claimed to be the first combination brought together, that would admit of success in steam navigation; a large portion of which was of his own invention. Indeed, his machinery was identical in all its essential principles with that used at the present day in the smaller class of boats for river navigation, especially upon the western waters; and nearly identical with that used on the first boat Fulton built upon the Hudson in 1807, which has given him so wide a reputation as the reputed inventor of steamboats. Feeling a strong assurance of success, he had high hopes and anticipations, and looked forward in the ardor of his purpose to the accomplishment of a wo:rk that promised so great a revolution. He hoped, motle NATHAN READ AND THE STEAM-ENGINE. 97 over, to share in the benefits of his inventions, and thus obtain a compensation for his labors; and he took measures at once to secure a patent for his improvements. His first step was to lay his inventions before the Academy of Arts and Sciences,1 and obtain the views of that Society in regard to their originality and importance. Both subjects were examined by a Committee of the Society, upon which they made report, and gave him the following certificate thereof, namely,"At a meeting of the'American Academy of Arts and Sciences,' April 1st, 1784, — Voted, That Richard Cranch, Esq., Loammi Baldwin, Esq., the Rev. Joseph Willard, and Mr. Caleb Gannett, be a Committee to receive such applications, as may in future be made to the Academy; and after examination had of any piece of machinery, which they shall judge of public utility, and worthy a patent, they are hereby authorized to give such testimonials, in behalf of the Academy, as they may think expedient.'

"We, the above-named Committee, have examined draughts of improvements proposed by Mr. Nathan Read of Salem, in this Commonwealth, in the steam-engine, and its application to the moving of water (boats) and land carriages. By reducing the size of the apparatus, and yet enlarging the evaporating surface, much originality is discovered, and very beneficial effects will in our opinion be secured, exclusive of the saving in the article of fuel. It appears to us that the advantages proposed by a steam-engine will be enjoyed in a greater degree, with less inconvenience and at a smaller expense, on this construction than on any other within our knowledge.

Congress at this time was in session in the city of New York. With the above testimonials, his plans and drawings, and the models of his steamboat and land carriage, he went to New York, and on the 8th of February, 1790,- about two months before the passage of the "Act to promote the Progress of the Useful Arts," - presented a petition to Congress for a patent. The following is a copy of his petition, so far as it relates to the subject under consideration l 1_ "' To the Honorable Congress of the United States: The petition of Nathan Read of Salem, in Massachusetts, respectfully showeth;.... that he has also invented a portable steam-engine, which may be constructed with less expense, is much lighter, occupies less space, and requires far less fuel, than any other within his knowledge.

The machinery for communicating motion to boats, vessels, land carriages, etc., is very simple, and takes up but little room.1 " The models, draughts, and descriptions of the above-mentioned machines, engines, etc., having been critically examined, and the principles on which they are constructed fully approved as just and philosophical, by a select committee of the American Academy of Arts and Sciences, and by several other gentlemen, eminent for their skill in mechanics and every branch of physics, your petitioner is induced from the extraordinary expense, which in a young country always attends first essays of every kind, to solicit such aid from this honorable body as will enable him to bring into general use such machines, engines, etc., as may be judged worthy of particular encouragement, in consequence of their subserviency to other arts and manufactures, and their direct tendency to facilitate the inland trade and navigation of the country, as well as to enhance the value of the Western Territory, by having the effect of diminishing its distance from the seat of government. Your petitioner also prays, that the benefits of his inventions and improvements may be secured to him, his heirs, and assigns, for such term of years as Congress may think fit. "; NATHAN READ. " NEW YorK, February 8, 1790." He spent most of the winter of 1789-90 in New York, and exhibited the plans, drawings, and models of his boat, and also of his steam-carriage,to President Washington (to whom he had letters of introduction from General Benjamin Lincoln), and also to members of Congress and other gentlemen there; among whorn 1 See his Specification, post. NATHAN READ AND THE STiEAll-ENGINE. 101 were several distinguished mechanics, and explained to them the principles of his machinery.1 While in New York he boarded at Mrs. Wheaton's, in company with Dr. Cutler and General Rufus Putnam, who were attending upon Congress as the agents of the Ohio Land Company. They introduced to him John Stevens of Hoboken, who called upon them at their quarters. At this time, Read explained to Stevens, who took a deep interest in the subject, the principles of his " multi-tubular boiler," and its adaptation to boats and land carriages; and in the mean time exhibited to him the plans and drawings of his boat with paddle-wheels, and his mode of turning them by his improved cylinder, etc.2 Stevens at that time had become interested in steamboat projects, which was probably unknown to Read. He had appeared before the New York legislature as the competitor of Rumsey on his application, before that body, for his water-ejecting steamboat, pipe boiler, and raising water for mills; and in conjunction with Rumsey, in opposition to the law which Fitch had previously obtained, for building steamboats in that State.8 And this same winter that he examined Read's plans and drawings he left the New York legislature (followed by Rumsey and Fitch), and presented his petition to Congress for a patent for generating steam and for propelling vessels by steam. It is probable that the examination of Read's plans and drawings, and his models (for it seems he had his models with him), gave Stevens,a new impulse in his steamboat projects. 1 See Judge Read's letters to Timothy Pickering and D. Read, post. 2 Letters of Judge Read,post. 3 See page 128, post. 102 NATHAN READ AND THE STEAM-ENGINE. Read's steamboat was designed to be moved by the "multi-tubular boiler " he had invented, his improved cylinder, acting under Watt's double-action principle, and paddle-wheels; and his engine carried by high steam, to be used with or without a condenser. This properly fitted it for river navigation with boats of small size; river navigation being then the sole purpose in view. The following is a copy of his description of the boat, or specification connected with the drawings:" Description of a boat or vessel to be impelled through the water and against the stream of rapid rivers, with great velocity, by means of float-wheels moved by the steamengine. A. The hulk of the boat or vessel. (See Plate III. Fig. 5.) B. The Portable Boiler, in the bottom of the boat. C. The new constructed cylinder, firmly fixed at such distance above the boiler, as to admit the axis of the floatwheels to turn freely and to be raised or lowered as occasion requires. D D. The float-wheels, the floats of which should be large in proportion to the size of the boat, and the velocity with which it is to be moved. B E. Pinions fixed on the axis of the float-wheels. F.

Two racks on each arm of the working frame, each of which has a set of flexible teeth alternately moving the pinion the same way. One rack or set of teeth turns the pin7 ion as the plunger descends, and the other rack on the: opposite side towards the pinion the same way when the, plunger ascends; in consequence of which the float-wheelsw 0 lf I ci-. PO;i I.3i I;T- - I -.1 ' Vz Q *a d;L, NATHAN READ AND THE STEAM-ENGINE. 103 have a continually progressive motion. The flexible teeth in the racks are so formed as always by their own gravity to keep their proper places, and be ready to act. A continually progressive motion may also be given to the boat by means of two movable wheels and clicks, which alternately move the pinion on the axis of the float-wheels, and constantly turn it the same way. Either method in practice is very simple, and the work contained within a very small space. There may be a small forcing-pump to convey the water reproduced from steam in the condenser directly back into the reservoir, which is much more economical than to supply it with cold water." The Congress of 1789-90, being the first after the close of the laborious and stormy work of establishing the Constitution of the United States, was as yet but imperfectly organized. It was moreover crowded with business of the most important and exciting character; and had but little time or thought to bestow upon applications of a private nature. In the mean time no patent laws or regulations had been established or patent granted by the General Government. Soon after his petition was presented to Congress the " Act to promote the Progress of the Useful Arts " was passed, constituting the Secretary of State, Secretary of War, and Attorney General, a board of commissioners, to whom all matters of this character were to be referred; and his application thereupon came before the Commissioners. He first asked for a patent for a boat consisting of paddle-wheels, his newly invented boiler, and improved cylinder, and for land carriages driven by steam.1 But unluckily for the petitioner, in looking 1 Ante. 104 NATHAN READ AND THE STEAM-ENGINE. over some of the old volumes of the 4" Transactions of the Royal Society," he chanced to notice an article, relating to an experiment a long time previous, in France, in which it was related, that paddle-wheels and oars both had been tried, to see if they would not control the action of a ship of war in a calm, which experiment before that had never come to his knowledge.1 Erroneously supposing that such experiment interfered with his right to a patent for a boat with paddlewheels, he withdrew so much of his petition as related to them; and under date of January 1, 1791, presented a new petition, and substituted a new propelling agent, which he denominated a " rowing machine," which he had invented and constructed upon the principle of the chain-pump, working in a horizontal position, parallel to the keel of the vessel, with one half of the chain and paddles under water and the other half out. This, he believed, would answer the next best purpose to paddle-wheels; but he reluctantly made the change, as he considered the paddle-wheels the preferable mode.2 But laboring under the impressions stated, and feeling bound to obey the provisions of the law, that seemed to require something wholly new and never before thought of, he took a patent for a boat to be propelled by the rowing machine, for his portable furnace boiler and improved cylinder, as shown by the patent heretofore inserted.8 1'See letters to Timothy Pickering and D. Read,post. 2 Post. 3 Extract from Specification: " The rowing machine will revolve like the chain-pump, and the paddles on the lower half of the chain will be continually passing from head to stern in a direction parallel to the keel, NATHAN READ AND THE STEAM-ENGINE. 105 It can hardly be doubted, even at the present day, but that the chain-wheel may be applied with tolerable success to boats for river navigation; yet that it is equal to the simple paddle-wheel for river or ocean navigation, is not to be allowed; this sufficiently appears from the adoption and general use of the latter. Such, indeed, was the opinion of Read, and he was entitled to a patent for paddle-wheels; certainly as much as Fulton was, when he (Fulton) received his patent for them in 1811, twenty years after. And it is but just to allow to Read, as much for his original and avowed purpose of using them, as if he had actually patented them; they formed a part of his original steamboat. If the above view of the case be correct, it follows that Read's true combination of machinery for his steamboat, consisted of Watt's double-acting principle, with his own tubular boiler, improved cylinder, and paddle-wheels; a combination of machinery that essentially makes up the inland steamers of the present day.1 We may be the more justified in looking at the broadside against the water, and impel the vessel forward, while the paddles on the other half of the chain pass back from stern to head, out of water, without resistance. This motion by a crank may also be given. The size of the machine should be increased or diminished, according to the power applied and the resistance to be overcome." 1 The multi-tubular boiler is used at this day in many English boats. Its tubes are placed in a vertical position, and the water instead of the flame passes through them. The tubes are used in the sanie way as in Read's boiler but shorter. The drawing may be found in the Encyclopcldia Britannica, vol. xx. p. 651, which remarks, - There are three kinds of marine boilers in use in this country, namely, the rectangular flue boiler (which is:now very generally discarded), the multi-tubular boiler, or as it is more uisually called, the tubular boiler, and the shut-flue boiler. The tubular is that in most general use, in which a large heating surface is crowded into a very small space, and the form of the tubes affords great strength. Shut 106 NATRHAN READ AND THE STEAM-ENGINE. subject in the above light, as we consider how much bulk and weight he had dispensed with in his improvements; the furnace and boiler, instead of occupying two separate positions, were now reduced greatly in size and occupied but one position, while the power was increased; the condenser might be dispensed with also, or retained if desired; a large share of the expense of fuel was provided against; and although his plan of a boat shows the application of the double rack and pinion for turning the wheels, yet in his specification of the chain-wheel, the idea of applying cranks, if found on trial to be preferable, is secured. But the racks and pinions having flexible teeth, worked as well backward as forward, and would produce a continuous rotary motion to the wheels as well as a crank. But experience has shown that the crank is the preferable mode; yet either may be worked by the double-acting engine. The paddle-wheel had been rejected by Fitch, and also by Perrier, partly on account of the oblique resistance it met with, as the paddles entered and emerged from the water; I which difficulty would be greatly increased as the boat was laden; as the wheels would thereby be deeper immersed and become useless. Read had anticipated this difficulty, and to obviate it, as may be seen from his description of his boat, he so constructed them as to be raised or lowered as occasion might require. In giving the rotary motion to his flue boilers are constructed with numerous flats, with spaces between them, alternating with water and flame, from one and a half to two inches apart. These are more durable against oxydation from salt water, and were used in the vessels of the Peninsular and Oriental Companies." 1 Ante. NATHAN READ AND THE STEAM-ENGINE. 107 engine, it would seem that he proposed the rack and pinion or crank, as desired, though his draught is after the former mode. Both were contained in his specification on which he secured his patent, and it will be recollected that he used a crank to turn the wheels of his boat when he made his first experiment with it at Danvers. At this day, now that cranks have become so familiar from their use, the idea of using the rack and pinion would be regarded as somewhat crude; but as he considered either of them practicable, it seemed to be his purpose to secure both, and leave it for future experience to determine their comparative utility. The invention of a continuous rotary motion was no modern thing; whether it had its origin in Egypt, Arabia, or China, no one knows; but it had been in use ever since the invention of the potter's wheel, or of the common turning lathe; which are moved by the foot by means of a treadle united to a crank by a connecting-rod. The old fashioned spinning-wheel, used for twisting the thread of the flax, as drawn from the distaff with the thumb and finger, is a machine of the same sort; yet strange as it may seem, when cranks had been in such long use for these purposes, and in conStant operation for ages before the eyes of the world, no one, until about 1780,' conceived the idea that they could be applied to any other possible use than to turn the simple machines above named. Pickard, about 1780, happened to think of applying them to a horizontal shaft to be moved by steam; 2 and the idea of making the steam-engine turn a crank, was about the same time also conceived by Watt, and put in oper1 Life of Watt, p. 180; Irving's History of the Steam-engine. V2 Ibid. 108 NATHAN READ AiND THE STEAM-ENGINE. ation by him, in the Albion Mills, which was in 1787,1 only the year previous to Read's improvements of the steam-engine. No fly-wheel was required for his carriage or paddle-wheel boat, to carry the motion beyond the dead points of the piston, as the wheels themselves were all that was required to perform that service. Of course he would make no representation of a flywheel in his plans. 1 Ante. CHAPTER XI. THE name of John Stevens, of Hoboken, has been mentioned in connection with his steamboat projects. He was then a man of extensive wealthl and great perseverance, and the father of John C. Stevens and Robert L. Stevens, who since that day have distinguished themselves so much in steam navigation upon the Hudson. Stevens seems to have become somewhat enthusiastic on the subject of steamboats,2 and, backed up by. his extensive means and partiality for mechanical pursuits, he resolved to try his fortune in the attempt to build one. He, as before noticed, soon after his examination of Read's drawings and model, petitioned Congress himself for a patent for generating steam and for propelling vessels by steam. Thus his petition and Read's became pending before the House of Representatives at the same time. This called the attention of Congress to the subject of patents, and it was referred, on the 8th of February, 1790, to a special committee, consisting of Messrs. Burke, Huntington, and Cadwallader.3 The result of these petitions was that the committee reported to the House the bill "to promote the Prog1 Renwick, p. 283. 2 Life of Fitch, p. 383. 3 Journal of the House of Representatives, p. 30, A. D. 1790. 110 NATHAN READ AND THE STEAM-ENGI.NE. ress of the Useful Arts," which was passed on the 10th of April following. In due time the Board of Commissioners, consisting of Thomas Jefferson, John Knox, and Edmund Randolph, was organized under the act. Fitch, however, was displeased with some of the provisions of the act, and had no great liking for Mr. Jefferson. He hence resolved to petition Congress directly, instead of the Board of Commissioners, asking for an independent law granting to him the exclusive right of propelling boats by steam in the waters of the United States, which Congress refused. This petition was dated July 1, 1790, and some five months after Read and Stevens had made their applications to Congress. Fitch being now turned over to the provisions of the general law, along with the rest, afterwards, on the 22d of November, 1790, sent in his petition directly to the Board.1 Rumsey also had a petition pending before them, presented by his agent, he then being in England. Rumsey's petition was for a boat propelled by ejecting water at the stern; Fitch's for propelling with oars or paddles, and by forcing water or air through a trunk; Read's for his multi-tubular boiler, improved cylinder, and for a boat with paddle-wheels; and Stevens for propelling vessels by steam, and for a new mode of generating steam.2 It may be well here to notice, that the history of the respective cases precludes the idea that any of the other petitioners could have derived their inventions from Stevens; while, on the other hand, the claims of Stevens, and the propriety 1 Ante. 2 Post. NATHAN READ AND THE STEAM-ENGINE. 111 or justice of his petition for a patent for propelling vessels by steam, and for a new mode of generating steam, as the original inventor, was questioned. During these proceedings, Read had noticed the experiment in France with paddle-wheels, as before stated.1 His business before Congress had been brought before the Commissioners, after the passage of the act, by two new petitions direct to the Board, - one presented April 16, 1790, for his improvements upon the steam-engine, and the other April 23, 1790, for his method of moving land carriages by steam, and propelling boats or vessels by the same agency by paddle-wheels, etc.2 To simplify the business, he withdrew both of the above petitions, and presented his petition of January 1, 1791, in lieu of them. In his last one he left out his land carriage, and substituted the chain-wheel for paddle-wheels. After thus arranging his papers, Mr. Remsen, the Secretary of the Board, wrote himn as follows, as the Committee had been expected to meet in February: — " PHILADELPHIA, January 25, 1791. "SIR:- The Commissioners named in the'Act for the Promotion of Useful Arts,' judging it most expedient not to proceed further in the business thereby committed to them, until a Bill supplementary to said Act, and which is now before Congress, passes, have directed me to inform you, that the hearing of the parties who have applied for patents for the discovery of new applications of steam to useful purposes, cannot take place on the first Monday in February, which was the time they had assigned for the purpose; but 1 Ante. 2 See his draught and description of his steamboat, before given, Ante. 112 NATHAN READ AND THE STEAlM-ENGINE. that they will be duly informed of the day as soon as it is fixed. " I am, sir, your most obedient "Most humble servant, "HENRY REMSEN, Jun. 1 "Mr. NATHAN REED." Previous, however, to the above letter, Read had written to Mr. Jefferson, inclosing to him his petition of January 1, 1791, and in this letter says:" Having improved some of the machines for which last winter I solicited a patent, and desirous after further improvement, and communicating others to the public, I must request your Excellency to solicit the Honorable Board to grant me leave to withdraw my former petitions, paying all charges that have arisen, and to present the inclosed petition, in which I have stated, agreeable to the order of the Honorable Board, the nature and extent of the discoveries therein mentioned..... I have requested Mr. Remsen, by permission of the Honorable Board, to inclose me my former petitions, and to deliver to my order several models, which have too long incumbered your office." The above new petition does not differ from those previously presented, except in the changes before mentioned; and its terms are fully shown by the several specifications, heretofore noticed and filed in the Patent Office on the issuing of the patent. On returning the old petitions Mr. Remsen writes as follows: -- " PHILADELPHIA, February 5, 1791.

They suffered no injury by the removal, having been carefully packed with paper shavings in a box provided for the purpose. I have concluded to hand this to Mr. Goodhue for transmission, as his franking it will save the postage that would accrue on its being sent without a frank, and as its going by that conveyance is certainly safer than by stage. You will excuse me for observing, that your last petition substituted for the two now returned, does not include as many objects as they do. Your application for a machine for moving and directing land carriages by steam, is not therein renewed, although it should have been if you still persist in it. I should have retained the petition No. 2, had you not inserted in the last one sent your improved method of impelling boats or vessels through water, because it contained your claims for these two objects. You may however draw it over again, leaving out what is included between the brackets, and send it as soon as you please. " I am, sir, with due respect, "Your most obedient servant, "HENRY REMSEN, Jun'r. " Mr. NATHAN READ." We may now look upon these several projectors prosecuting their claims before the Commissioners for a common purpose- the invention of the steamboat; and each one aiming to secure letters-patent from the government, granting exclusive privileges in steam navigation, according to the several plans they presented. At that time, the great work of applying steam to navigation in the United States was concen1 For these petitions, see Appendix, No. 4. 8 114 NATHAN READ AND THE STEAM-ENGINE. trated in the efforts of these men. Miller had abandoned his experiments, and all was quiet in Europe on the subject, and Fulton was at work as a journeyman painter in the studio of West in London; and the idea of engaging in any steamboat project, was as foreign from his mind as the Atlantic Telegraph, and sixteen or eighteen years had yet to pass before his first boat would appear upon the waters of the Hudson. It is now a conceded point, that American enterprise and genius produced the steamboat; and it may be well to look at this point of time, and this nucleus of projectors, to determine how large a proportion of that enterprise and genius is due to them? And here again, a just discrimination should be made between these men, to see who among them had done the most to change and fit the steam-engine for the work. Rumsey had tried his brief experiments upon the Potomac; but had done nothing to improve the steam-engine and prepare it for navigation. Fitch, with indomitable perseverance, had succeeded in driving his boat six or eight miles per hour; and by constant repairs run it for some time at a daily loss. Did he reach the secret of success; and wherein did he leave the steam-engine any better fitted for navigation, than when he found it? Stevens had sought to acquire a knowledge of steam force from such sources as suited his convenience, and took this occasion to place a petition by the side of the others for a patent. The Com. missioners met on the 4th of April, 1791, and agair on the 22d and 23d of the same month. After these meetings of the Commissioners, Mr. Remsen agail writes to Read as follows - NATHAN READ AND THE STEAM-ENGINE. 115 "PHILADELPHIA, July 1, 1791. "SIR:- I received your letter of the 18th of May last a few days since.1 The Commissioners, at their meeting in April, agreed to grant patents to all the claimants of steampatents, so far as they had applied steam to useful purposes, without taking it upon themselves to ascertain whether those claimants were really the inventors, as they severally alleged in their petitions. Accordingly John Fitch for applying steam to navigation; James Rumsey for generating steam, applying it to navigation, and to raise water; yourself, (and) John Stevens for generating steam, applying it to raise water, to work a bellows, and to propel a vessel; and Engleback Cruise to apply steam to raise water, are all to have patents. But neither these or any other patents have as yet issued, owing to the absence of the President, who will sign them, and two of the Commissioners. I presume they will all be finished ready for delivery by the last of this or beginning of the next month, till which time no certain opinion can be formed as to the amount of the fees each patentee will have to pay. By a late order of the Commissioners you will have a patent for your applications of steam which will come to - including the expenses to which the patentees are subjected by law for their petitions and specifications — about five dollars. I return you the models you first lodged, being twelve pieces in the whole, and if you find among them any not belonging to you, I must request the favor of your sending them back. These models are the only ones I am not perfectly acquainted with; they were deposited in IMr. Alden's time, and consisting of many pieces, got mixed with other models, in the removal from New York. I also return your specifications that you may execute them in the customary form, and you may put them under cover to Mr. Jefferson when executed. You will be so good as to menI No copy of this letter is found among Judge Read's papers. 116 NATHAN READ AND THE STEAM-ENGINE. tion to him whether the models,1 which Captain Needham will deliver to you, are the same you lodged with the Commissioners in New York. When the patents are made out, I will let you know it. "I am, sir, with respect, "Your most ob't humble servant, " HENRY REMSEN, Jun'r. " NATHAN READ, Esq." Patents were afterwards issued to each of the above claimants, under date of August 26, 1791, according to their respective applications, on the principles indicated in the above letter of Mr. Remsen. These were the first patents ever issued under the authority of the United States. Read's was for his portable furnace-boiler, constructed internally with seventyeight small tubes, and his improved cylinder;2 and to each of the petitioners, himself included, for applying steam to navigation by such modes of propulsion as they respectively claimed in their petitions, leaving it for the patentees to settle the controversy between themselves whenever their patents should be found to clash with each other. Were we allowed to question the judgment and justice of such men as Thomas Jefferson, Henry Knox, and Edmund Randolph, who constituted the Board of Commissioners, we might say that this was not only a novel, but unjustifiable procedure. The duty of this very Board was to settle and decide upon the respective claims that came before them, and not turn over the parties to the 1 It is much to be regretted that these models have not been preserved. They are not among the effects left by Judge Read at his residence; nor did he leave any memorandum showing what became of them. 2 See his patent, specification, and drawings, ante. NATHAN READ AND THE STEAM-ENGINE. 117 adjustment of their rights by a wholesale system of litigation, more intolerable perhaps than a voluntary surrender of those rights. It does not appear, however, that any litigation grew out of this dilemma between these patentees; but this was owing more to the incredulity of the public in their steam projects, and the consequent discouragement they met with at that early day in the prosecution of their labors, than to the position in which the Commissioners left them. I deem it proper, however, to notice that none of the other patents granted on that occasion came in collision with Read's; 1 neither of the other parties claimed the portable furnace, alias multi-tubular boiler, improved cylinder, or chain-wheels. But the claims of Fitch, Rumsey, and Stevens clashed in several respects. Fitch's patent was, - "For applying the force of steam to trunk or trunks, for drawing water in at the bow of a boat or vessel, and forcing the same out at the stern, in order to propel a boat or vessel through the water. For forcing a column of air through a trunk or trunks, filled with water by the force of steam. For forcing a column of air through a trunk or trunks, out at the stern, with the bow valves closed, by the force of steam; and for applying the force of steam to cranks and paddles for propelling a boat or vessel through the water." 2 Rumsey's patent was, - "For propelling boats or vessels by means of the reaction of a stream of water, forced by the agency of steam. See Read's patent and specifications, ante, p. 48. 2 Westcott's Life of Fitch, p. 327. [118 NATHAN READ AND THE S TEAM-EArGINE. through a trunk or cylinder, parallel to the keel, out at the stern; and for a more ample and easy mode of generating steam, by passing a small quantity of water through an incurvated tube X placed in a furnace, whereby the action of fire is communicated to the water and steam in all its passage from the entrance to the exit, and which kind of boiler can be easily adapted to every species of fire or steamengine; and for raising water by steam for the turning of mills, or for agricultural or other purposes." 1 Stevens's patent did not differ essentially from Rumsey's, being for generating steam with a like boiler, and propelling his boat in a like way; by forcing water through a trunk by steam and ejecting it at the stern of the vessel; and also for raising water for mills, etc., and working a bellows.2 It will thus be seen that the patents of Rumsey, Fitch, and Stevens, clash in several particulars; but that neither of them interferes with the patent of Read. 1 This description is taken from Rumsey's specification of his steam inventions as presented by him to the New York Legislature, and is supposed to be the same as that he soon after presented to Congress. -Docum*entary History of NYew York, vol. ii. p. 1099. 2 See Report of Committee of New York Legislature, on the Petitions of James Rumsey, John Stevens, and John Fitch, in 1789.-Ibid. p. 1092. CHAPTER XII. THERE is an item in this history that should not be passed over here. In December, 1788, James Rumsey petitioned the Legislature of New York for a grant for propelling boats by forcing water through a trunk, for his pipe-boiler, and for raising water for mills, etc., by steam; and on the 9th of January, 1789, John Stevens (alias John Stevens, Jr., as then called) also presented his petition to the Legislature of New York, for a grant similar to that applied for by Rumsey. Fitch, who had obtained a previous grant from the legislature, remonstrated against these petitions; and the subject having been referred to a special committee, consisting of Messrs. Livingston, Havens, and Van Cortland, they reported: — "' That nothing in the act, securing to John Fitch the exclusive right of propelling boats by fire or steam, can be construed to prevent the legislature from securing to James Rumsey, for a limited time, the exclusive right of generating steam, by his new invented method of a pipe-boiler; and further, that they have examined the petition of John Stevens, and the draughts accompanying the same, and are of opinion, that the method proposed by him for propelling boats by steam, does not materially differ in its principles from the mode proposed by James Rumsey, and that he stands in the same situation with respect to John Fitch as the said James Rumsey." 120 NATHAN READ AND THE STEAM-ENGINE. The Committee reported a bill to secure to Rumsey his pipe-boiler, and rejected the petition of Stevens; Rumsey's bill, however, was not passed by the New York Legislature, and Fitch's rights in that State remained undisturbed.1 The above proceedings before the Legislature of New York, show several important facts, namely, that the controversy between Fitch, Rumsey, and Stevens, commenced in the New York Legislature, in an attempt there made by Rumsey to supplant Fitch, and overturn the rights he had acquired under his act, and of Stevens to supplant them both, in an effort to secure a grant, which Fitch and Rumsey contended did not belong to him, either by invention or priority; that the applications of Rumsey and Stevens were substantially for the same thing; each having a like mode of generating steam, propelling boats or vessels, and raising water for mills, etc.; that the pipe-boiler, so much talked about, consisted of one single incurvated pipe, holding about three gallons of water, twisted about in a brick furnace, and giving no opportunity for steam to escape from it but at one end, while the other end received the water from the reservoir,2 From these facts we are enabled to distinguish between their pipe-boiler and Read's multi-tubular boiler; and, moreover, to learn that Read incidentally met these three contestants before the Board of Commissioners, free from any concert or collision with them; 1 Documentary Htistory of New York, vol. ii. p. 1092. 2 See specification of James Rumsey, Documentary History of New York, vol. ii. p. 1099, and affidavits of Charles Morrow, p. 1027, and Joseph Barnes, p. 1028. NATHAN READ AND THE STEAM-ENGINE. 121 and that Rumsey and Stevens, after trying their case before the New York Legislature without disturbing the rights of Fitch there, removed their controversy, and sought to obtain from the General Government what they could not get from the State of New York. To show that Read's patent was clear of any interference from the others, we need only make the proper distinction between the pipe-boiler, patented to Rumsey and Stevens, and the multi-tubular boiler, patented to Read. This distinction may, to a considerable extent, be at once seen by looking at the diagrams of the pipe-boiler and furnace, on the opposite sheet, and comparing them with the drawings of Read's multi-tubular boiler and furnace.' But to see how entirely unlike they are, we are not only to look at the form of their construction, but at the more important difference there is in their power and capacity for generating steam, and in their strength, durability, and safety. The following is Rumsey's description of the pipe-boiler, now in the possession of the American Philosophical Society, in his own words: 2 " A B C, an iron pipe bent as represented by the figure; D F, a pipe of the same size with the valve E, on the turned-up end. The end F, is brazed to the boiler A B C, at B, and hangs down in a perpendicular direction to discharge the steam at the valve E, when the machine is not at work. This boiler is set up in a furnace of brick, and the fuel put into the cavities formed by the crossings of the pipe. The water that makes the steam is forced in at the end A, by a small pump. The advantage of this boiler is, that it presents a much greater surface to a small fire 1 Ante. 2 See No. 11, on opposite sheet. 122 NATHAN READ AND THE STEAM-ENGINE. than any other. The furnace is two feet square inside; one hundred and twenty feet of pipe, two inches in diameter, is bent as represented in the diagram, the surface of which will be sixty feet square,1 all of which will be in the fire, as the fuel is to be burnt in the cave made by the crossing of the pipe, and must therefore be very hot." 2 From the above description and diagrams of Rumsey, and the specification and drawings of Read,3 we are led to a full discovery of the dissimilarity of the two boilers. The eye can determine the difference in the form, and no comments on that subject are required, as they are at once seen to have little or no resemblance to each other in this respect. We will then proceed to inquire in general terms into their power and capacity for generating steam. The pipe-boiler exposes sixty square feet of surface to the fire, and but one single aperture of the size of the interior diameter of the pipe, for the steam to escape from, at the extreme end of the pipe where it is connected with the cylinder. The multitubular boiler (invented to be longer or shorter at pleasure), allowing it to be but six feet in length, and the average length of the tubes but five feet, there being seventy-eight tubes proposed in the drawing, would expose one hundred and ninety-five square feet of surface to the fire, and have seventy-eight apertures for the steam to escape from. This makes one aperture to every two-and a half feet of surface exposed to the fire, the same the pipe-boiler had for 1 He means sixty square feet, as is shown by the length and diameter of the pipe. 2 Westcott's Life of Fitch, p. 228. 8 Ante, p. 50. NATHAN READ AND THE STEAM-ENGINE. 123 sixty feet. In short the pipe-boiler had but one of these apertures, while the multi-tubular boiler had seventy-eight of the same size. It will moreover be seen, that the multi-tubular boiler ejects the steam from the upper end of each of these seventy-eight tubes, into an apartment at the top of the boiler, where the steam is compressed, and from whence, as the cocks are alternately opened and closed, it rushes through a steam-pipe of sufficient size and capacity to conduct it to the cylinder; while the steam from the pipe-boiler is conducted directly to the cylinder, without an opportunity to acquire force from compression. This would reduce the power of the pipe-boiler even below the comparative amount of steam it was capable of producing; but the amount of steam it produced, when compared with the multi-tubular boiler, may be readily seen by the most inexperienced eye. How much better would a pipe be one hundred and twenty feet in length, resting in a furnace in a series of incurvations, within a space of two feet square, and exposing sixty feet of surface to the fire, than one but twenty feet in length, of the same size, and exposing but ten feet of surface to the fire? This is a question that can be answered only by a series of experiments with exactness; but it is selfevident, that a pipe one hundred and twenty or but twenty feet in length, and only two inches in diameter, exposed in the manner described to the intense heat of a furnace, would, either of them, generate as much steam as could pass out at one end. If such be the case, a pipe one hundred and twenty feet in length is no better than one of but twenty. But here is 124 NATHAN READ AND THE STEAM-ENGINE. another matter to be considered: in a hot furnace the water would occupy but the first part of the pipe, and the steam the other part, and it becomes an inquiry of some importance, what effect the heat of the furnace would have upon the steam as it passed through one hundred feet of pipe intensely heated? If it could not find vent and wholly escape from the end of the pipe, the pipe itself must explode; and oxydation would soon destroy it, if not destroyed by the expansive force of the steam. There could, moreover, be neither strength, durability, or safety, in the pipe-boiler. However well it might be constructed, the heat of the furnace, as well as the expansive force of the steam and oxydation, would destroy it; and if the heat should be raised very high, it would at once fuse that part of it unoccupied by water. Fitch was persuaded to try it once, against his opinion of its utility, and then it exploded, and he flung it aside. Rumsey had the utmost faith in it, although "it kept melting off his solder and coming to pieces." At best, its power was limited to very light work; and it was wholly worthless for navigation, or any use where the ordinary power of steam was required. The multi-tubular boiler, on the other hand, is capable of exerting the highest degree of steam-power, not only for driving mills and factories, but for propelling vessels of the largest class,l -every part of it 1,i The Great Eastern is supplied with three distinct modes of propulsion — paddle-wheels, screw-propellers, and sails. The engines for driving the paddle-wheels are horizontal, of which there are four; they are of one thousand nominal horse-power each, with four cylinders 74 inches diameter, and length of stroke 14 feet, with 15 revolutions per minute.
