THE importance of a science, or of an art, may proba- bly, in most cases, be considered as proportional to the attention which it has received from mankind in general, or to the degree of perfection which it has attained. This method of testing the importance of an art cannot, however, be said to be correct in all cases. There are, we believe, some very important arts, which have been overlooked by the majority of men, and which have consequently not kept pace with the progress of knowledge. Among these, the ART OF MINING is to be ranked. The subject to which we propose to call the attention of this Society, in the present communication, is one which has been very incorrectly judgejl of, even by those upon whose authority we are accustomed to rely in every respect. The art of mining has been, we apprehend, misjudged by the generality of writers ; and many individuals have been led into false and disastrous speculations, by engaging in under- takings of this nature, without having sufficiently studied and comprehended the subject. The errors of writers upon this matter have chiefly resulted from their having treated it too slightly, or too exclusively. Thus, many distinguished au- thors, among whom we may rank the celebrated author of the " Wealth of Nations," have underrated the art of mining, because they had not sufficiently examined its nature and object. They have often mistaken the greedy speculations of the first adventurers in South America, and the visionary plans of the settlers in the country so pompously styled El Dorado," for the steady, persevering, and arduous labour of the true miner. They have overlooked the advan- tages which England has derived from her coal and iron mines, and have only noticed the ruinous speculations of ill-advised adventurers: as well might we undervalue the fcOtfSIDERATIONS UPON advantages of commerce, on account of the failure of the South Sea scheme. Other authors, again, have treated this subject too exclusively. This defect exists chiefly in the works of German authors, who, blinded by their partiality for their profession, would have given it a degree of import- ance to which it was not entitled. Their wish was to see introduced into large monarchies the same institutions which had been found to answer in the small communities which composed the German empire, and of which a few still sub- sist, having weathered the political storms of the last thirty years. But a system which answered in a small principality, in which the sovereign acted for the most part like a father of a family, (possessed, it is true, of great powers and privi- leges* but not regardless of the interests of his subjects,) could not be adopted in larger communities, where the king acts under the influence of his ministers, and where he cannot be directed by those paternal feelings, which, it is but justice to acknowledge, often actuated the lesser princes of Germany. Still less could the plans recommended by these authors be adopted, or even approved of, in this country, where we are so jealous of the rights of property, that nothing but the most imperious necessity could induce us to part with any of those rights. The art of mining is one of the most important branches of public economy. The nature of this art, the objects which it embraces, the studies which it requires, the be- nefits which result from it to man, both by administering to his necessities and by increasing his comforts, and, finally, the great assistance which it offers for the successful prose- cution of natural science in general, tend to make it one of the noblest and most interesting pursuits to which the atten- tion of man can be called. It is, we believe, almost impossible to determine with pre- cision the influence which the art of mining has had in civil- izing mankind. The imagination can scarcely conceive the wild and blank state of a nation destitute of all the metals, salts, and fuel, which we derive from mining. There is, we would be induced to believe, but one stage lower than this THE ART OF MINING. 5 in the scale of human ignorance, and it is that of those In- dians who are said to have been unacquainted with the exist- ence of fire. The art of working the metals must, in the origin, have heen the effect of a first advance towards civilization ; since which, it must be considered as a cause, as well as an effect, of civilization. Every improvement in this art must necessarily have had a striking effect upon the state of soci- ety; which effect was again reflected upon the art from which it sprung. Whatever may have been its influence in producing the present refined state of society, no question can exist as to its importance and advantages at this time. When we consider that the most valuable aliments we take are pro- duced by agriculture, and that agriculture must cease to exist as soon as it is deprived of the assistance of the metals, w r e can readily conceive how essential this class of substances is to our existence, and how valuable is the art which teaches us to convert the crude and brittle ore into the malleable, pure, and polished metal. But these are not the only henefits which it affords us. The wool which we manufacture into cloth could never have assumed that form, if it had not previously undergone opera- tions in which metallic instruments are indispensable. The habitations which protect us against the inclemency of the weather, from the cottage of the peasant to the palace of the monarch ; in a word, every art which tends to the support or comfort of life, all evince the indispensable use of metals. The origin of the art of mining, like that of many others, must have taken place at a very early period, and the date of it is not to be ascertained. The oldest books with which we are acquainted speak of it in very plain terms : Thus, in the Genesis, 5 * we find it written : "And Zillah, she also bare Tubalcain, who was an in- structor of every artificer in brass and iron."f The discrimination of the metals must have taken place * Chapter IV. verse 22. j- We find a different version of this text in other Bibles, where Tubalcain is said to have been "a hammerer and artificer in every work of brass and iron," 6 CONSIDERATIONS UPON as soon as man began to look around him. Accordingly, we find, in the description of the spot where the Garden of Eden stood, speaking of rivers,* " That is it w r hich compasseth the whole land of Havilah, where there is gold." " And the gold of that land is good : there is bdellium and onyx stone." Again, we find it stated,f that "Abram was very rich in cattle, in silver, and in gold." In the writings of Homer and Hesiod, the oldest profane authors whose works have been handed down to us, frequent allusions are made to the metals ; and some interesting ob- servations on the state of the art can he extracted from them. It would be an useful and an interesting task for the anti- quary, to endeavour to ascertain the manner in which the ancients smelted their ores and worked their mines^ No doubt, their first attempts were rude, and on a small scale ; but on such a subject, all additional information, however minute and trifling in appearance, would be interesting. It would throw much light on the progress of civilization ; and it would be very desirable that a person well skilled in the dead languages, and w r ell acquainted with the metallurgical processes now in use, w r ould endeavour to trace the progress of the art from its origin, and to determine the respective periods at which each metal was first made known and brought into use. But it is enough for us to have called the attention of the antiquary to this subject. We cannot enter into details, but hasten to the main object of this communication, which is to draw the attention of the Society to a subject which may be- come highly interesting to our country. " Sella quoque genuit Tubalcain qui fuit malleator at faber in cuncta opera <( aeris et ferri." If the word malleator (hammerer) be not an interpolation of the transla- tor, it presents us this interesting 1 observation, that the ancients had already noticed that property of metals which we call malleability, and that they pu- rified their metals by hammering, * Chapter II. verse 11, 12. t Chapter XIIL verse 2. THE ART OF MINING. 7 We shall divide what is to be said on this subject in three parts. In the FIRST SECTION we shall state the object of mining, and the various operations which the miner has to perform. We shall make known the sciences upon which his art is founded, and the manner of applying them. In the SECOND SECTION we shall examine the nature of mining, ascertain to what class of property mines belong, and determine the importance of this art compared With others. The THIRD SECTION shall include a short sketch of the actual state of the art in Europe; to which we will add re- marks on the advantages which might accrue to the United States from the introduction of this art. We shall inquire into the obstacles which might retard or obstruct the pro- gress of mining in this country ; and what course should be followed in order to overcome these obstacles. SECTION FIRST. Of the objects of mining, and of the operations which the miner has to perform. Of the sciences upon which his art is found- ed, and of their application. The art of mining is that which teaches us the manner of obtaining and preparing for the use of man the metals and other substances which exist in the mineral kingdom. The metals are seldom found pure : when pure, they are termed native. For the most part they exist intimately mix- ed, or chemically combined with other metals, and with sul- phur, oxigen, and other bodies. In this state they are call- ed ores. Iron, the most useful of all metals, has, perhaps, never been found native; lead and tin, certainly never; zinc and cobalt are always extracted from their ores. The na- tive mercury and antimony are so rare as to be merely ob- jects of curiosity; and all the mercury and antimony of commerce, are obtained by extracting these metals from their CONSIDERATIONS UPON combinations with sulphur. Copper is often found native ; but always in small quantities. It is from its ores that it is produced in greatest abundance. Silver is often, and gold always, found native ; and these, with the addition of plati- na, are the only metals which exist in sufficient abundance in the native state, to make it an object to work them in that state. But besides the substances which are chemically combined with the metals to form the ores, there are a number of others which are only mechanically mixed, and which can be easily separated. These are for the most part earthy minerals. The task of the miner may be said to consist in the fol- lowing operations : to find the ore to extract it from the bosom of the earth to raise it to the surface to separate the substances which are mechanically mixed and then to submit the ore to such metallurgical process as shall purify it and free it from all tbe substances which remained in che- mical or mechanical union with the metal. In a word, to bring the metal to that state of purity which is required for the arts. But, in the performance of these multifarious du- ties, the miner will meet with obstacles ; these he must re- move or overcome. Thus he will find himself in the midst of loose and disaggregated materials, which threaten him with instant destruction. To this he must bring a remedy. Again, he will meet with great volumes of water which would soon inundate his works if he could not find means of remov- ing them. In some cases also, the light which he uses to guide his uncertain steps, becomes his most dangerous enemy; it inflames the atmosphere, an explosion takes place, and the miner has ceased to live. To this evil a remedy has been applied by that great and powerful genius, Sir Humphry Davy, whose safety lamp insures him the gratitude of all concerned in these dangerous works. Our task would be endless if we were to attempt to enumerate here every obsta- cle which the miner has to encounter. We will now proceed to examine the various attainments necessary to the perfect miner : THE ART OF MINING. 9 1. The knowledge of minerals, or MINERALOGY. This teaches him to distinguish the useful from the unproductive minerals ; to ascertain the nature of each substance, and the use to which it may he applied. Without the knowledge of mineralogy, the miner would he led into innumerable mis- takes. This is, as it were, the corner stone of his edifice. 2. The knowledge of the distribution of minerals upon the surface of the earth. This science forms a part of GEOLOGY. By it we are enabled to determine with a greater or less de- gree of certainty, where, and under what circumstances, we may expect to find the minerals we are in search of. It serves to inform us how far we may be justified in searching after certain ores, in certain rocks ; and, as an instance, we may mention, that the miner acquainted with the first rudiments of geology, would not search for tin ore in a bed of chalk, any more than he would expect to find rock salt in granite. For want of sufficient regard to this science, great expense has often been unnecessarily incurred by boring or pitting for coal. In many places, expensive works were commenced by uninstructed men, who merely took into consideration the advantage which might be derived from the discovery of this fuel, without reflecting whether they were warranted in so doing by any reasonable expectation of finding it. But we must be very guarded in the application of our geological notions, because they are not founded upon demonstrated facts or impossibilities, but merely upon analogies. It is because tin ore has always been found under circumstances very different from those in which we find chalk, that we are induced to believe, a priori, that it will not be found with it. But there is no physical impossibility in its being found in the United States in a different situation from that which it presents in England, Germany, France, and Mexico. We should be directed, not blinded, by analogy ; we should con- sult it as a prudent, but not an infallible adviser. 3. The third branch of the miner's studies is DOCIMASY, or the art of analyzing minerals. To this branch we are in- debted for all that we know of the component parts of each mineral. It is upon docimasy, that the great responsibility 10 CONSIDERATIONS UPON (if I may here apply the expression) of the miner's success rests. Without docimasy, mineralogy would be a science of but little use. The mineralogist, it is true, might probably distinguish his minerals without, as well as with, its assist- ance ; he might give them names, and call them a, 6, or c, but it is the docimastic chemist, who, having analyzed them, determines their nature, and affixes their value ; it is he who stamps upon them the rate at which they are to be received in commerce; it is he who tells us that what the mineralogist had called a, was an ore of iron, which might be worked with advantage to procure this metal ; that the b of the mi- neralogist was an useful stone, from which lime might be obtained for the arts; while his c had no intrinsic value; that it might indeed adorn his cabinet, or be made to sparkle in the hands of the able jeweller, but that it never could be of any use in the arts. Thus the docimastic chemist may be said to give value to the science of the mineralogist. But he goes further ; after he has determined that a given mine- ral is an ore of a certain metal, he tells us with what sub- stances it is combined, in what proportion the metal exists, whether the combination be an intimate mechanical mixture, or a real chemical combination, in definite proportions. And this is not all ; he tells us if the ore can be worked with ad- vantage, and in what manner; whether any, and if any, what substances are to be added or taken away in order to reduce it to that state of purity which is requisite in the arts. Thus we see how necessary to the miner is an acquaintance with docimasy, and how often, and how severely that man may be disappointed, who looks for success without a previous ac- quaintance with this science. 4. The fourth branch which enters into the studies of the miner is the knowledge of those indications by which we may determine the extent and importance of a mineral deposit, the existence of which has been previously ascertained. This is indeed a very important branch of his art ; it is one upon which much depends in a new country ; we will, therefore, not hesitate to speak of it in detail. It is a common idea, that a person acquainted with mining, can, from a mere in- THE ART OF MINIXG. 11 spection of the surface, decide whether there are any mines under ground. This opinion is, however, incorrect; the richest ores may be covered hy a layer of vegetable earth, which conceals them entirely from the observation of the miner. The characters taken from the general appearance of the ground, as respects roughness or evenness, have long been supposed to be useful in the hands of the skilful miner ; but we would observe, that the loftiest and most rugged peaks of the Alps present no mines whatever, while the level and fertile plains of Poland and Belgium cover rich deposits of coal, iron, lead, zinc, salt, &c. It was at one time imagined, that the presence of metallic deposits produced a sort of in- ternal fermentation, which impeded the progress of vegeta- tion, and stinted the growth of trees ; to this we answer, that the German empire, than which none is richer in mines, was at one time a complete forest, and covered with the finest trees. To the beauty and richness of these forests, the Ro- man authors have borne testimony ; and it stands upon re- cord, that the whole of the present rich mining district of Freyberg in Saxony, was at one time one of the thickest and wildest forests in the empire, and that its trees had attained an uncommon size. It is true, the land is now bare, and scarcely does an " occasional pine" shade the cottage of the poor miner ; but this we must attribute to the works of man, and not to the action of the veins placed there by nature. How could it be otherwise, in places where we see that the ground has been broken up in every direction, where heaps of rubbish have been formed, and subsequently scattered up- on the country, and where the very streams which support- ed the vegetation, have been diverted from their natural course, and made to run into new channels ? Another indication, which has been used, we believe, not with the purest of motives, was that of the divining rod. Men were led to believe, that with the assistance of a rod, ge- nerally of hazle, or some such wood, the presence of mines, of salt, of springs, in a word, of every thing that was wished for, could be discovered. Secret treasures, it was reported, owed their discovery to this means. To those who reflect 12 CONSIDERATIONS UPON how great an influence the astrologers have possessed over mankind, and how apt the imagination is to be carried away hy a sort of admiration for every thing which hears the ap- pearance of being supernatural, it will be no cause of won- der, that in the dark ages of superstition and ignorance, the belief in the divining rod, like that in witchcraft, dreams, fortunetelling, c. should have existed not only in the multi- tude, but even in many men superior to the time in which they lived. Indeed, such deceptions are so fascinating, that there are perhaps few persons who have read the brilliant descriptions of the power of the magic wand in the oriental tales, and have not felt a secret disappointment at the recol- lection that it was but an airy vision, and a wish that it might be embodied into reality. This disposition for the marvellous being incontestable, it is not surprising that cun- ning impostors should have existed, who found it their inter- est to increase this belief, and to keep up the hopes of their votaries by pretended discoveries and wonders, the explana- tion of which could not have been readily given to, or under- stood by, the unenlightened multitude before whom these were performed. But as men became more enlightened, and as they felt the necessity of discrediting every thing which could not be proved, the confidence in the powers of the di- vining rod declined, and there are but few, we believe, who place any reliance in it at present. We would not even have dwelt so long upon this subject, if we had not seen, in a la'te very respectable publication,* the divining rod mentioned as an agent, whose efficacy was still the matter of doubt. We repeat it, the miner has but few indications to direct him in the search of ores ; it is chance which throws them in his way; the richest mines known have been discovered by the merest accident. The labourers in the fields are those who have the best opportunity of discovering the first indicia of a mine; the plough accidentally turns up a stone which the ploughman picks up ; its weight surprises him ; it sparkles in the sun; it has the characters of a metal; he takes it * Silliman's Journal of Science, No. 7. (Vol. 3, No. 1.) THE ART OIT MINING. 15 home with him, and shows it to his neighbour ; the fame of his discovery is soon spread about, and magnifies as it proceeds ; some traveller acquainted with the subject visits the spot, and ascertains the nature of the mineral found ; all this is the mere effect of accident, but here begins the work of the mi- ner; here he may display his ingenuity, or apply the experi- ence which he has acquired; he is told that the specimen which he holds was found in the adjoining field; he examines the field ; he compares the specimen ; he studies the country ; visits the valleys ; observes the pebbles rolled by the neigh- bouring streams, and endeavours by a careful search to trace back to its original situation the specimen which had been accidentally detached from it. Should his researches prove successful, should he have found the vein or bed, he examines its nature, ascertains its extent, begins his works, sinks his shafts, and endeavours to determine, by pitting and boring, the importance and value of the mineral deposit. It is at this moment that the true character of the miner may be tested ; he must neither fall into despondency at the first fail- ure, nor be allured into hasty and hazardous undertakings at the first appearance of success ; he must not be cast down because the path which he was following has suddenly dis- appeared, but he must endeavour to fall in again with it, by prudently directing his steps in the neighbourhood; if the thread which guided him in the labyrinth has been suddenly cut off, he must not despair, but lighting the torch of science, he must endeavour to recover it, and having obtained pos- session of it, he may be enabled to renew his search after the concealed treasure. If the miner who is too easily dis- couraged loses the chance of succeeding, and allows fortune to escape him, he who falls into the other extreme is still more to be blamed ; he not only brings ruin upon himself, his family and his friends, but he destroys the reliance which might be placed in his character and abilities; he injures the profession of which he is a member, by taking away from it the small degree of certainty which it possesses, and making it appear as a tool in the hands of an impostor. The prudent and skilful miner will therefore endeavour to 14 CONSIDERATIONS UPON steer a middle course, free from the dangers which threaten him on both sides ; he loses no time, overlooks no indication which may assist him, considers, examines, studies every ap- pearance, reflects maturely, and then decides whether the deposit be worthy of his attention or not ; he may be mista- ken in his decision, but he has acted prudently and wisely, and whatever result attends his future undertakings, he al- ways feels proud at the consciousness that he has done all that he could do, and that in his profession, as well as in every other, a man may deserve and not obtain success. 5. The fifth branch which the miner has to study, is the manner of working the mine ; properly speaking, Hoc opus, hie labor est." This consists in the knowledge of all the va- rious operations which are performed under ground ; these operations cannot be well described on paper; it is impossi- ble for a person who has not visited a mine to form a cor- rect idea of its nature, or to imagine the subterraneous world which exists there ; without having witnessed them, it is not easy to conceive the nicety which is required in some of the miner's works, the certainty with which he directs himself by the mere assistance of his compass ; the accuracy with which he executes, under ground, the operations which he has designed on his draughts and map. The works which the miner has to execute are the sink- ing of pits and shafts ; the opening of galleries, levels, and drifts ; the excavating of large chambers for the reception of machines, &c. the detaching of the ore from the rock, &c. All these works he executes either by the assistance of iron and steel tools, such as pickaxes, hammers, wedges, &c. or by blasting the rock with gunpowder, in which case, he uses the drill, rammer, priming rod, &c. or finally by the applica- tion of fire ; this last method, which is practised with advan- tage in many instances in Germany, Sweden, and Russia, and which can be applied with great success wherever the rock is tough, wood cheap, and powder expensive, is very interesting. It consists in erecting large piles of wood near the rock intended to be taken down, setting the wood on fire, and directing the flame and smoke in the manner that will THE ART OF MINING. 15 produce the greatest effect upon the rock, which is expanded and rent in all directions, by numberless fissures ; new fuel is added, and the fire kept up for several days, at the end of which the miner returns to the spot of the conflagration, and easily detaches, with his pickaxe, the rock, which, before the application of the fire, was very tough and compact, but which afterwards almost crumbles into dust of itself. To this and the preceding branch we must refer the know- ledge, so essential to the miner, of following the traces or indications of a vein which has partially or completely dis- appeared. This branch includes likewise the whole disposi- tion of the works under ground. It therefore requires, on the part of the miner, experience and study, to know how 7 to direct and dispose the works, in order to extract the ore with the greatest economy. It is a branch in which rules can scarcely be laid down. Every mine requires a peculiar dis- position, and it is only by comparing his mine with those which exist in other places, that the miner can arrive at a good and satisfactory disposition of his works. To this branch we must likewise refer the knowledge of the best me- thods used to judge of the strength and quality of powder, of the resistance which it can overcome, and of the quantity ne- cessary to attain a certain object ; also, of the proper manner of applying it in mines. 6. We have said, that in the accomplishment of his work the miner met with great obstacles, which it was necessary for him to remove. The first of these is that arising from the pressure of the roof and sides of the excavations which he has made. The knowledge of the methods used to over- come this difficulty, constitutes the sixth branch of the art of mining. It is an observation of every day, that if an exca- vation be made in the soil, and left to itself, it will, after some time, become partly closed up by the lateral pressure ; and if it were intended to make the excavation in sand or gravel, it would require great care to prevent the sand from falling into the hole as soon as made. Every body, however unacquainted with the art of mining, knows that when a well is dug, unless it be opened in the solid rock, it is indispensa- 16 CONSIDERATIONS UPON ble to build up a solid wall of stone or brick round the well. It is true, many imagine this to be built for no other purpose than to keep in the water, but the main object is to prevent the sides of the well from falling in. If this be the case when a well of thirty or forty, or at most one hundred feet, is dug, how much more important when the shaft extends to a depth of from fifteen to sixteen hundred feet,* when the dimensions of the shaft are much larger, and when it traverses many different beds, some of tough and hard rocks, others less so- lid and compact, some of loose and disaggregated materials, some of clay, sand, &c. the whole very much impregnated with water it is evident that in sucli a case the difficulties must increase in a tenfold ratio. Besides these, the miner has often to open large subterraneous chambers, the roof and sides of which are far from being solid ; these chambers, how- ever, require to be constructed with a great degree of solidi- ty, as they are intended for the reception of large and ex- pensive machines, such as steam-engines and water-wheels, in which case, the constant agitation of the air, by the mo- tion and fail of water, tends to destroy the equilibrium of the rock, at the same time that the spray and moisture necessa- rily proceeding from such machines, act as a corrosive upon the rock. These chambers are sometimes intended for the accommodation of horses, sometimes for mills for the pound- ing of ores, &c. : hence it is evident, that the greatest care should be bestowed upon their solidity. The miner has two ways of propping the sides of his excavations. The first is by carpentry, the second by masonry. The proper applica- tion of these two methods is not unattended with difficul- ties. It is, generally speaking, much cheaper to use tim- ber than stone ; but the works of stone, if well made, may be considered as everlasting in mines, while those of wood re- * The shaft called the Richischact, at the mine of Beschert Gluck, near Freyberg, in Saxony, extended, in 1820, to a depth of 1981 feet, on a vein, the inclination of which is about forty-eight degrees. The shaft is in its upper part perpendicular : after a certain depth, it follows the inclination of the vein. This vein lias been very productive in silver ore, and is known by the name of JVeu hohe JBirkner Sfehende Gam*. THE ART OF MINING. 17 quire frequent repair, and a total renewal after a few years. It is not enough, therefore, to consider the comparative pri- ces of each ; hut we must also take into consideration their respective durability, and the time which it is intended that the works shall last ; for, in mines, some works are intended to be permanent, while others are merely temporary ; some are expected to remain open as long as the mine shall be worked, while others are only worked for the ore which they contain, and are abandoned as soon as that ore is exhausted. In the latter works, no doubt can exist as to the advantage in using timber in preference to stone ; for not only it is much cheap- er, but in many cases a great portion of the timber used can be removed to another place, and the materials are not therefore lost. But in the permanent works, the question is more difficult to decide. In Germany, where timber is becoming scarcer every day, masonry has been substituted with advantage in many mines where timber was formerly exclusively used. In this country, it is probable that timber will, for a long time to come, offer a great economy over stone works. Next to the choice of materials, the miner must attend to the study of the form and disposition of the carpenter or mason's work. These, of course, depend upon the form and nature of the excavation, upon the object for which it has been made, upon the solidity of the rock, the quantity of water, &c. We shall not enter into particulars, which would unnecessarily lengthen this communication, but merely observe, that this branch of the miner's art includes a knowledge of the strength and resistance of timber, of the solidity of building materials, of the manner of making ce- ments, of the construction of arches, of the forms best adapt- ed to each particular case, and of the calculations of the forces necessary to break them, &c. 7. It is a well-known fact, proved by daily experience, that if a well be dug, it will, at a certain depth, which varies according to the nature of the rock, and to the locality, be- come partly filled with water. Nay, it has been observed, that in some places, the water will spout out in the form of a jet d'eau. This circumstance, so useful in common life, since 3 18 CONSIDERATIONS UPOX it allows man to fix his habitation far from running water* is the source of much trouble and of great difficulties to the miner; for as soon as his excavations have attained a certain depth, the water runs in from all sides, inundates his works, and would compel him to abandon them, if his ingenuity could not devise means of keeping them dry. The study of the means used to accomplish this end, constitutes the seventh division of his acquirements. Th object which he has in view is twofold ; either to prevent the water from entering into his excavations, or to drain it off when it has penetrated into them. If the first method were practicable in all cases, it would undoubtedly be far preferable ; but this, unfortunate- ly, is but seldom in his power; the means used to prevent the water from entering the excavations being the damming up of the side from which it comes, and opposing a strong bar- rier in that quarter. This method is, however, impossible when the waters come from all directions, as is frequently the case, or where they proceed from the direction which the miner intends to follow, as usually happens in mines worked upon veins. Under these circumstances, the miner must think of removing them. He has two ways of attaining this end. The first is to give the waters an outlet, by opening a drift, communicating with the surface at some distance. The water is made to take its course along this drift. When this re- source fails, from the nature of the country, the depth of the mine, or some other reason, the only means left is to have recourse to pumping engines. The pumps are set in motion hy animal, water, or steam power. The animal power is in some cases that of man ; more usually it consists of horses. As the pumping of the water is always attended with a vast deal of expense, this operation is avoided as often as possi- ble. A drift, or drain, is therefore opened whenever the local circumstances admit of it. Some drifts are made at great depths, and extend to great distances.* It is generally con- * The length of the drift in the district of Freyberg, including all the branches connecting it with every mine, measured, in 1819, 70,000 German Lachters, or upwards of 90 English miles. What an immense undertaking ! and how great must be the advantages of drifts, in order to compensate for such subterraneous aqueducts ! THE ART OF MINING. 19 sidered, that the money laid out in drifts is very soon repaid by the economy of the pumps. Drifts, moreover, offer this advantage, that they allow the miner to carry his works to a much greater depth. This branch of the miner's studies comprehends, therefore, the art of making dams ; that of excavating the rock, as in the third subdivision of this section ; the knowledge of me- chanics, hydraulics, and hydrostatics; the science of ma- chines, and of their proper disposition and application. 8. Another and a very important branch of the miner's studies, is that of ventilating the mine, so as to procure a constant supply of pure air. This object is particularly enti- tled to the attention of the miner, since not only the security of the mine, and the durability of the materials, depend upon it, but even the preservation of the lives which are intrusted to his care, and for which he must consider himself respon- sible, should any accident happen through his carelessness or neglect. The air in the interior of mines is generally pure, but it requires a constant renewal ; for the oxigen which it contains is continually absorbed by respiration and combus- tion, and converted into carbonic acid gas. The inflammation of gunpowder likewise tends to diminish the quantity of oxi- gen in the air, by giving rise to new compounds, which do not support life and combustion. If, therefore, a regular and perpetual current of air were not kept up, the atmosphere of the mines would become so foul as to cease to support com- bustion, the lights would be extinguished, and, after a cer- tain time, its action upon animal life would be fatal. In some cases, a new cause operates, in like manner, to corrupt the atmosphere. This is the foul air produced by the rock itself. It occurs principally in coal mines, where the coal constantly emits a quantity of gases, which not only cannot support ani- mal life, but even in many instances are susceptible of being inflamed, and give rise to explosions which have often proved fatal to many of the workmen employed in the mines. Some coal mines, particularly in England, produce so much of this inflammable gas, that it had been found impossible to keep lights in them, until the late discovery of the safety lamp, to 20 CONSIDERATIONS UPON which we have already alluded, and which has hitherto an- swered in every case in which it was properly applied. In the invention of this lamp, Sir Humphry Davy has shown the great benefits which may result from applying theoretical knowledge to practical use. Having found, by a series of interesting experiments, that the flame of a candle could not pass through a metallic gauze of a certain fineness of tex- ture, he conceived the idea of enclosing the miner's lamp in a cylinder of iron wire gauze, so secured as to prevent any communication of the flame with the air of the atmosphere, except through the holes in the gauze. The experiment has been crowned with the most complete success ; and this in- vention is undoubtedly one of the most valuable to humanity. The miner has several ways of ventilating his mines, all of which are attended with more or less expense. To enable him to apply these methods with judgment, propriety, and economy, is therefore the object of the eighth branch of his studies. It includes, likewise, the knowledge of the best means of lighting the mines, and of the various kinds of lamps and torches which have been used. 9. The ninth division of the miner's acquirements is the carriage of the ores in the mine from the spot whence they are extracted to the bottom of the shaft, and then the raising of the same from the bottom to the mouth of the pit. The first part of this task requires some acquaintance with the nature of a mine, and some experience on this subject ; for the carriages under ground are attended with greater difficulties, and a much greater expense, than those, at the surface. There are various methods ; one of the least known, and which is very seldom used, probably not so often as it might be with advantage, is that of internal canals, the drifts being used for that purpose, and the ore being conveyed in small boats. A very pretty application of this method exists in the neighbourhood of Alston Moor, in England, where boats of upwards of five feet in breadth are navigated upon this subterraneous canal. As to the raising of the ores to the month of the pit, it is done by means of machines, for the most part similar to, and THE ART OF MINING. SI often connected with, those used for pumping out the water. To the division which treats of the pumping of waters, this part may therefore be referred. 10. The tenth branch, which the miner ought to study, is that of dressing the ore. By dressing the ore, we understand the operations practised to cleanse it of all the heterogeneous particles with which it is mechanically mixed. These ope- rations consist in picking, pounding, washing, &c. This matter has been neglected in England to an astonishing de- gree. In France, it is better understood ; but it is chiefly in Germany that it is to be studied. Nowhere has the art of dressing the ores been brought so near to perfection. It is almost impossible to conceive, without having seen it, how far the Germans excel all other nations in this important subject. The first improvements in this art are due to the Hungarians, whose ingenuity was brought into play by the desire of extracting the gold which exists in a very trifling quantity in the sands of their rivers, and also disseminated in the earthy gangue of their veins. The first improvements made by the Hungarians were subsequently introduced into Saxony and the Hartz, where the poorest silver and tin ores are worked, with a degree of economy almost incredible. The operations in dressing the ores have for their object to separate the substances which are mechanically mixed with them, and which are commonly called gangue, or often very improperly, matrix. In the washing of the ores, many differ- ent plans have been pursued ; but of these, none is so advan- tageous as that of the shaking or percussion tables, which are set in motion by water-wheels, and, from their peculiar construction, economize about four-fifths of the hands for- merly employed for the purpose of washing the ores. 11. We have seen, that among the operations of the art of mining, many required the use of machines which it is often desirable to set in motion by a water power. This power is not always at hand : it must be procured from a distance, which is accomplished by means of canals and aqueducts. In some of the more considerable mining districts of Europe, these aqueducts are made of a great length, and often extend 22 CONSIDERATIONS UPON to twenty miles, and even more. To be enabled to construct these aqueducts, it is necessary to be acquainted with civil engineering, and it certainly would be very desirable that any man who has any pretensions to be reckoned a perfect miner, should not be a stranger to these operations. Num- berless cases will occur, in the working of a mine, in which the operations of the mining engineer differ but little from those of the civil engineer. 12. But a much more important branch of the miner's pur- suits, one to which all the others are directed, and by which the ore is most effectually improved, is that of METALLURGY. Metallurgy, or as it has been more properly termed of late, MINERALURGY, is that portion of the miner's studies which enables him by the action of heat, assisted by other agents, for the most part chemical, to counteract the affinities which unite the various components existing in the crude products of the mines, and to separate from them the substance which was the object of mining, in order to reduce it to such a state of purity as will render it fit for the various purposes for which it was intended ; it not only separates the bodies che- mically combined, but also those which are mechanically united in quantities too minute, or by a mixture too intimate to admit of a separation by picking and washing, &c. It is, therefore, by the assistance of metallurgy that we are ena- bled to separate and extract silver, lead, and copper, from some combinations in which they are mixed with iron, anti- mony, arsenic, zinc, sulphur, lime, magnesia, and other sub- stances, whose names are only known to those who have made a study of chemistry. Metallurgical operations are the last which the miner has to perform. They are, at the same time, the most compli- cated, and the most difficult. It is not enough for the metal- lurgist to separate the greater part of the metal, but he must separate the whole, if possible ; and what is more, he must do it with great economy. He must not be satisfied with the re- sults which he has obtained ; he must constantly endeavour to improve his process. Metallurgy is a science in which much remains to be done. It is, therefore, incumbent upon THR ART OF MINING. 25 the metallurgist to be ever watchful, and to endeavour to at- tain a greater degree of economy and precision. This he may be able to effect by studying well all the operations practised at this time, and those which have been formerly practised, but have since been abandoned. He must endea- vour to ascertain why they have been given up. He must inquire into the rationale of all his operations ; examine and analyze all the products obtained. By these, and similar means, he may hope for success. Among the most important branches of the metallurgist's studies, is, undoubtedly, that of the construction of his fur* naces. It is one on which too much care cannot be bestow- ed. He must, likewise, become well acquainted with the na- ture and quality of the various kinds of fuel used, the pro- cess of converting wood and coal into charcoal and coak, &c. The principal operations used by the metallurgist to at- tain his end, are the roasting, smelting, amalgamating, cu- pelling, and refining, of the ores. If mineralogy be the cor- nerstone of the miner's studies, metallurgy may with justice be said to be its keystone. It is metallurgy which completes, which perfects the work. We might easily have lengthened this review of the studies of the miner, by adding a number of branches, and making several subdivisions, which we have avoided in order to re- duce it to as small a compass as possible. Nor have we in- cluded in the studies of the miner, that of mining jurispru- dence, although it is considered in Germany as an indispen- sable part of his studies. Every officer of mines employed in the kingdom of Saxony, is compelled to attend two years the lectures of the Law Academy at Leipsick, and it is not until he has undergone examinations upon jurisprudence, that he is received as officer of mines. We would not has- tily or rashly censure regulations which have been found to answer during centuries, and which come down to us sanc- tioned by experience and time ; but we would observe, that although this study may be very necessary in Germany, where the laws and regulations on mining are numerous and 24 CONSIDERATIONS UPON complicated, it does not appear to us that this study is more necessary to the American miner, than to the possessor of any kind of property whatsoever, or to the man following any other profession. A general acquaintance with the laws of his country is what every man ought to have ; more than this we do not helieve to be necessary to the miner. We now proceed to examine upon what sciences the art of the miner is founded, and how he is to apply them. From what has heen stated in the preceding pages, we think it apparent that the art of mining is founded upon four sciences ,* viz. Mineralogy, Natural Philosophy, Mathematics, and Chemistry. Mineralogy is indispensable to the miner in order to re- cognise the minerals when he sees them. Natural Philosophy is necessary, as it comprises statics, mechanics, hydraulics, hydrostatics, and magnetism, which, as we have seen, are useful to the miner in draining the mines of the water they contain in raising the ores to the surface in resisting the lateral pressure of the rock in ventilating the mine in directing his course under ground by means of the compass in dressing the ores in making aqueducts in constructing blasting machines for his fur- naces, &c. Mathematics are indispensable to calculate the force of his machines, and of his moving powers ; to enable him to make correct surveys of his subterraneous works ; to assist him in judging of the strength of his constructions both above and under ground. Upon correct notions of mathematics and natural philoso- phy depends the successful application of his machinery, whe- ther it consist of horse-engines, or steam-engines, of water- wheels, or pressing machines, &c. If ignorant of surveying, or of the laws which govern his compass, he never will be able to make the different parts of his works correspond with THE ART OF MINING. 25 each other. In vain will he waste treasures in endeavours to open drifts. He will always be foiled in his attempts, be- cause he was deficient in the first requisites. Chemistry is as necessary to the miner as any other science. Upon an intimate acquaintance with it, his success in a great measure depends. He must have made a close study of this science, both as respects the nicer operations of analytical chemistry, and the great principles of chemical statics, in order to be able to explain and account for the mutual and relative actions of the various substances which he wishes to treat in his furnaces, and to remedy all the ac- cidents which may occur. Docimasy and metallurgy, two of the most interesting and important branches of the mi- ner's studies, depend exclusively upon chemistry. He must, therefore, be master of this science, if he expects to succeed. If it be remarked, that the studies which we have present- ed as indispensable for the miner, are so various and so ex- tensive, so general and so difficult, as to render it impossi- ble for a single man to make himself thoroughly acquainted with them all, we answer, that we have intended to show what acquirements a man ought to possess before he could call himself a perfect miner. We are ready to acknowledge that it is impossible for any one man to be equally well skilled in all these branches. It is usual in all the great mining districts of Europe, to divide the task between seve- ral men. The isolated mines are confided, it is true, to the care of a single director, who, being unable to attend equal- ly well to the whole, directs his attention more exclusively to those studies which he thinks are most needed in the esta- blishment at the head of which he finds himself placed. But although we admit that a man may neglect or lay aside those branches of the miner's pursuits which he finds less impor- tant, (as for instance, metallurgy, if he be at the head of coal mines,) still, we think that he ought always to keep up a general acquaintance with the sciences upon which they are founded, in order that he may have recourse to them whenever he finds it necessary. 4 26 CONSIDERATIONS UPON But it is not enough to have learnt these sciences in the study or in the laboratory ; he must not think that mere the- oretical knowledge will avail him much. He must, on the contrary, endeavour to acquire practical information. He must visit the interior of the mines study the disposition of rocks examine the mariner in which the works are execut- ed nay, he must himself become an operator he must have handled the tools himself, or he never can expect to be a per- fect miner, or a good judge of the work executed by those under him. There is no art, perhaps, where it is more necessary, and yet more difficult, to unite practice with theory, than in the art of mining. The man who is a mere theorist, can never form a correct opinion of what a mine is, or how it ought to be work- ed ; he will never know what remedy to apply in case of a failure. Trusting to his drawings or to his calculations, every step which he takes may be in direct opposition to the ac- knowledged laws of nature. He assumes as principles, rules which have never existed but in his own imagination, and upon these establishes arguments, and draws conclusions, as false as the premises upon which they are founded. In the course of our very limited experience, it has been in our power to notice several instances of men, who, possess- ing very deep mathematical information, could have calcu- lated the exact resistance of a beam of wood, and the force necessary to break it ; but if brought into a mine and re- quested to give an advice as to the size of a piece of timber, which could resist the lateral pressure, in a particular case then under notice, found themselves completely at a loss for an answer, and acknowledged that all their theoretic know- ledge could not assist them in solving a question, which a mere practical workman in the mine, could, from analogy and by experience, answer without hesitation. At the same time, however, that we admit that theory alone will not avail a miner much, we should be sorry to see its advantages overlooked ; the mere practical miner is apt to be puzzled at the least difficulty ; he but seldom improves, generally retrogrades, or follows a blind routine. THE ART OF MUTING. 27 In order to avoid both evils, we believe it necessary to be acquainted with both theory and practice ; to trust in theory as often as its results are not in direct opposition with those of experience ; to take advantage of the reasonings a priori, in every instance in which the arguments a posteriori have not given a decided and incontrovertible answer ; in a word, to rely upon theory without being a slave to it. SECTION SECOND. Of the nature of Mining. Of the class of property to 'which Mines belong, and of the importance of the art of Mining compared with all others. A question which has often been debated among the au- thors who have written on mining, is, whether it ought to be considered as an art or a science ; but this is a mere scho- lastic puzzle, which has been applied equally to all branches of human knowledge ; the miner's profession has its theory as well as its practice ; the former entitles it to be ranked with the sciences, while the latter constitutes it an art ; it therefore partakes of both ; it requires an acquaintance with several sciences and several arts ; hence, it is, with propriety, neither exclusively a science nor an art ; but it is a sort of middle ground, upon which both may be said to meet. Another question, and one of much greater importance to the miner, is to ascertain in what class of property mines should be ranked, and if they are to be considered in every respect as real property ; there are probably some points of difference between mines and other kinds of property ; but the exami- nation of this question appertains more properly to the law- yer than to the miner ; we will therefore not enter into a discussion which is beyond our reach, but we wished to call the attention of the lawyer to this subject, which, we believe, has not been very closely examined. 28 CONSIDERATIONS UPOIt Whatever may have been the motives which induced le- gislators to separate this class of property from all others, certain it is, that in most countries, the mines have been made the subject of peculiar legislation ; we believe that it is principally to their importance to society in general, that we must attribute this distinction ; as the metals, the salts, and fuel which are extracted from mines, are admitted by all to be indispensable for the comfort, we might say, for the exist- ence of man, and as they are not to be found indifferently upon the whole surface of a country, but are restricted to particular spots and particular localities, it was thought ne- cessary for the general interest of society, to take away from the owners of these spots, the right of property to those sources of wealth $ for, if this right of property were vested in the owner of the land, it would be optional with him to work his mines, or to neglect them ; it would therefore be in his power to give to, or withhold from society the com- forts and means of subsistence, which depend upon the pro- ducts of mines ; these products being considered as a source of national wealth, were supposed to be national property, which ought to be disposed of in the manner best calculated to secure the interests of the nation at large ; it was argued in defence of this doctrine, that a river is not the property of the man upon whose estate it passes ; that he enjoys, it is true, all the advantages, and is liable to all the inconveni- ence, which result from its neighbourhood, without being the proprietor of its waters; that he can only take advantage of them, as long as the use he makes of them does not interfere with the general interests of society. When the in- justice of taking away from an individual his property, was urged as a motive against this mode of reasoning, it was an- swered, that the depriving an individual of a property, upon which he had not depended, could not be considered as an injustice done to him ; that he knew not of the existence of a mine under ground when he purchased the spot, and there- fore, that his schemes of profit were not founded upon it; that, when a law was passed to take away from the owner of THE ART OF MINING. 29 the soil, the right of property to the undiscovered mines which lay concealed in the bowels of the earth, he could at most be said to be deceived in the hopes which he might have entertained; that this measure, however, affected only the original proprietor, for every subsequent purchaser would be aware of the conditional tenure by which he held the land ; and that, although the case of the first owner was hard, it could only be considered as one of the many in which individual interests must be postponed to the general wel- fare. Another powerful motive for separating mines from other kind of property, and taking them away from the owners of the soil, was the great difference which exists between mines and lands devoted to agriculture, and which consists in this, that the former can be exhausted, or rendered useless to so- ciety by mismanagement in the origin,* while the latter pos- sess a perpetual power of reproduction ; that, if the pow- ers of the soil be exhausted by some cause or other, they can be restored and reproduced in a lapse of time never very considerable ; this is an argument, which, if fairly examined and duly weighed, will go very far; for if mines be produc- tive of great advantage to the community, it is essential for the general benefit of this community that they be worked, and their products brought into circulation ; but further, it is also necessary that they be worked with the greatest advantage and skill, in order that society at large may derive the great- est possible advantage, from a treasure placed by Provi- * We have said that a mine can be destroyed, or rendered useless, by mismanagement in the origin. We might cite many instances ; a single one will suffice. If a coal mine be improperly worked in the origin, large masses left unexplored, a free access of atmospheric air allowed to this coal, it will be very apt to inflame spontaneously, by the decomposition of the iron py- rites, which accompanies it in most cases ; the mine once on fire, there is no saying where or when the conflagration will stop ; some of these subterra- neous fires have been lasting two or three centuries; not only the coal is lost to mankind, but the surface of the soil has considerably suffered from the smoke and gases issuing, which have produced pressures in the soil, &c. and have destroyed the vegetation over extensive tracts. The great chasms formed under ground by the combustion of the coal, have caused the sink- ing in of the surface, and many other accidents. 30 CONSIDERATIONS UPON deuce upon the property of an individual, for the benefit of the community at large. Hence the great principle, upon which all the writers upon the law of mining seem to have agreed, that when a mine belongs to an individual, it is a property which he may use, but not abuse ; while all other properties which he possesses he holds in most cases with the privilege of using and abusing at pleasure. It has been further urged, in favour of taking away from an individual the right of property to the mines under his ground, that the division of property is always made with reference to the convenience of the owners of the soil, and that the mines which exist under its surface have little or no connexion with the surface itself, so that a division of pro- perty, made to suit the surface, may be such as to preclude the possibility of a mine under ground being worked by the owners of the soil separately ; whereas, if the privilege of the mines did not follow the property of the surface, but were vested in a single individual, this individual might work them with profit to himself and advantage to the community. It is from such motives as these, that the advocates of restric- tive laws upon mines endeavour to establish the expediency and justice of the right of Royalty. This regal right varies in every country. In some, the sovereign is merely entitled to a certain proportion in the profits, or to a share in the products. In other countries, the sovereign, besides his share in the products, has the exclusive right of disposing of the mines, and of conferring them upon those whom he thinks best calculated to secure the interests of the state. In some parts of Germany, the sovereign has moreover the sole right of directing the manner in which the mines belonging to in- dividuals shall be worked. Hence the creation of a regular body of officers, instructed in the art of mining, and to whom is assigned the care of superintending and directing all the mines of the country, whether they belong to the sovereign or to individuals. The creation of such a body of officers was followed by that of public schools and academies, where the art of mining is taught in all its various branches. To THE ART OF MINING. SI these institutions, no doubt, the art is much indebted for many of the improvements which have been introduced dur- ing the last century. But such a system is liable to great objections. It seems to us, that the establishment of officers for the special purpose of directing an individual how he is to employ his property, what expenses he must make, and what profits he may be allowed to derive from them, is an encroachment upon private rights, to which nothing but the most manifest expediency could induce us to accede ; and we believe this expediency has not been clearly demonstrated. We admit that there are many instances, in which the inter- ests of society at large, the security of the mines, and that of the lives of the men employed in them, would seem to justify, and even to require, an interference on the part of the legis- lators. Whenever such an interference can be proved to be necessary, we shall always be disposed to advocate it, even though it affect individual rights ; for in societies, it is evi- dent that the convenience of the few must yield to the inter- ests of the many. It is a rule so well established, that we shall not dwell a moment in bringing forward examples, and merely state, that whenever a road or canal is found benefi- cial to the country at large, no individual can object to its passing over his property, although it may occasion him serious inconvenience. There are numberless other instances which tend to prove, that the great basis of social life being that of mutual sacrifices for the public weal, society at large is perfectly justifiable in compelling an individual to abandon rights which are injurious to it. Our object, at present, is not to decide wbat course should be followed in the United States, and what laws ought to be made regulating the rights of miners ; and we even abstain from expressing any decided opinion as to the expediency of making any law whatsoever on the subject, our only purpose being to endeavour to call the attention of some able writer to this subject. We would wish that that writer could be found in that class of professional men, who, from the nature of their avocations, have made a particular study of jurispru- dence and of the rights of property, and who, from their 32 CONSIDERATIONS UPON general character, would, we are certain, take an enlightened view of the suhject, and lend their influence to support any measure, the object of which would he to open a new source of national wealth, and to make our country independent of all others as respects the products of mines, even though such a measure might in some respects curtail the rights of the owners of the soil. \Ve will merely state a few of the many instances which have been brought forward on this question, in order to show how, in some cases, legislative authority might be exercised with advantage. We merely assume, beforehand, what we believe to be correct, that there is no law of the United States, arid none of the state of Pennsyl- vania,* which can be said to apply particularly to mines. It has often been thought, that the privilege granted to sovereigns had been in many cases most shamefully abused, as, for instance, in England, where the right of royalty over immense territories was lavished by the crown upon indivi- duals who had no claim to it except through the favour of the monarch. It was to reward a chieftain who had been useful to him in wars, that the king would confer upon him the royalty of all the mines found in one or more counties, to the great and manifest injury of the industrious and useful part of the community. This right was afterwards sold and divided by these military lords and their descendants, so that they have now fallen into the hands of individuals who own them often without having any right to the soil under which they may be found. This privilege, originally assumed by the sovereign for the interest of the community, has therefore in this case proved of no use whatever to the state ; it has never benefited either the public or the king; but it has * The reservation of one-fifth of the gold and silver ores for the use of the state, cannot be considered as a law on mining, but merely as a restriction in the sale of the property. We may be allowed to observe, that this reser- vation is very immoderate; and must either prevent these ores from being worked, or give rise to great abuse. We believe that so great a reservation has been but seldom required, and we know of no instance where a greater one has been called for. The word ore is very loose, and will, we fear, give rise to great difficulties, if this law should ever come into operation, which we trust will not be necessary, THE ART OF MINING. 33 introduced a division of rights, which gives rise to great diffi- culties among landholders. In order to show how irregularly this right is now divid- ed, we may mention the instance of one of the richest com- moners in England, who holds immense estates in the north- ern counties, and whose lead mines are among the most im- portant in England. These lead mines are worked hy him 1st. On property belonging to him, and of which he has the right of royalty ; 2d. On property belonging to other in- dividuals, but of which the right of royalty resides in him ; 3d. On property belonging to him, but of which the royal- ty resides in other individuals, from whom he rents it ; 4th. And, finally, upon lands, the royalty of which belongs to the Dean and chapter of Durham, while the exclusive right of the surface belongs to a third party. Hence, it is evident, that the royalty in England has been but an additional right of patronage vested in the crown, and which has been used for no other purpose than to gratify the wishes of the favourites of the monarch. We may here observe, that the rights of royalty over every section of the country, have passed in this manner from the crown to in- dividuals ; the present king possessing the royalties of no mines except those vested in his person by virtue of his right of Prince of Wales and Duke of Cornwall. Having shown the origin of the right of royalty, together with some of the arguments for and against its expediency, we shall proceed to examine a few of the many cases, in which an interference, on the part of legislative authority, seems to be justifiable. Our first example shall be taken from a case which was peculiarly applicable a few years ago, and would have continued so to be, if the hopes which had been formed of the existence of a valuable mine had not been dis- appointed. Tin is a rare metal, but a very useful one. The only mines of it worked in Europe, are those of Cornwall, which are very rich and abundant ; and those of Germany, which are comparatively inconsiderable. But the greater part of the tin used in the arts, and the best quality, comes from Ban- 5 34 CONSIDERATIONS UPO3T ca and Malacca, and other mines in Asia ; it all reaches Eu- rope by the way of England. France possesses no tin mines. This metal is very useful in many of the arts, and particu- larly in time of war, as it enters largely into the composi- tion of gun-metal. In case of a war with England, France has no means of procuring tin, except at a great expense, from Germany; hut, in the event of a war with Germany and England, (as was lately the case,) France has no means of receiving any tin. Suppose a tin mine were discovered in France, and the individual on whose property it lay, from some motive or other, refused to work it himself, or to allow any other person to take advantage of it, would not the com- munity at large be injured by this individual's refusing or neglecting to work his mine ? might it not, in this case, be desirable that the power of disposing of the mine should rest in the hands of persons more apt to be actuated by the pub- lic welfare, than the isolated individual, whose patriotism is often stifled by private interest ? Again, there are, we believe, cases of a stronger nature in favour of some laws which would tend to facilitate the work- ing of mines. Suppose a landholder find a mine on his pro- perty, and that he be disposed to work it ; let it be, for in- stance, the same tin mine which we have just spoken of, and the importance of which to the community we have just es- tablished; but let us suppose, at the same time, that this mine could not be worked with advantage, unless a drift leading to a distant valley were opened, two or three hundred feet under ground, in order to drain the water. Suppose this drift have to pass under property belonging to other individu- als, who, from some motive or other, would refuse to grant to the holder of the mine the privilege of opening his drift, unless he paid them an extravagant compensation, or per- haps will not agree to any terms. The motives of these in- dividuals we do not examine; they may be actuated by groundless fears; perhaps by pique or jealousy at their neighbour's success ; perhaps by disaffection to the country in which they live, if the mine be of sufficient importance to affect its political situation. Is it not evident, that in such a THE ART OF MINING. 35 case, society at large may be seriously injured, the holder of the mine may find himself ruined, and foiled in his at- tempt to carry on works of public utility as well as private advantage, by the mere selfishness or obstinacy of an indi- vidual, who derives no benefit whatsoever from this line of conduct, and whose property can by no means be injured by a drift passing several hundred feet under ground ? Certain- ly no reasonable man could object to a law's being made which might benefit the miner in this instance, provided it were so restricted as not to prove oppressive in other cases. A third instance in which the interest of the public may be at variance with that of an individual, and with our actual legislation, is, where a mine could be worked with advan- tage to the public and to the proprietor, if he were allowed to bring a stream of water to his works, in order to set his wheels in motion; but that this water could only be procured by means of an aqueduct passing over the property of his neighbours. In the case of a canal, the objections of the owners would be overruled; why should they not likewise be disregarded in a case which affects society perhaps to as ex- tensive a degree ? What objections could be made to a law securing to a miner the right of making such roads and aqueducts as are indispensable for his works, requiring, of course, at the same time, that he should pay his neighbours a full compensation for the injury done to their property, the amount to be ascertained as it now is in the analogous case of canals, &c. ? But there is another point to which we would call the attention of the humane legislator. It is one which we con- sider as of much greater importance, inasmuch as instead of the property, it is the life of many valuable members of the community which it concerns. Suppose a man, care- less of the high moral responsibility which is attached to his situation as director of works of this nature, exposes the lives of the labourers whom he employs in dangerous works, which his ignorance or neglect has made him overlook, and which prudence and foresight on his part might have point- ed out to him. Suppose an accident happen which he might 36 CONSIDERATIONS UPON have prevented by a little attention, is such a director ame- nable before any tribunal? is there any law by which his presumption or his indifference can be punished? Will it bo argued, that there was no compulsion on his part, and that the workman who perished was a victim of his own impru- dence? will it be considered as a risk voluntarily encounter- ed by the uninstructed labourer? and will society be satisfied with a verdict of " accidental death ?" \Ve fancy not ; we hope not ; we trust some measure would be found to teach this careless director, that besides being responsible to his Maker, he is answerable to his fellow-citizens, and to the laws of his country, for a waste of human life which he might have prevented. Our object has been to show that there is good cause to inquire whether any law should be made, restricting or re- gulating the privileges of miners and landholders concern- ed or connected with mines. And if it is likely that such an interference on the part of the legislature shall become ne- cessary, we think it would be of great advantage that the laws should have been made before the case shall arise to which they may apply. In this manner, we would avoid every thing like an ex post facto law. Should we neglect to make the law at present, when the art of mining has scarce- ly taken a footing in the United States, we may be called upon to make it at a time when it would be applicable to in- dividual cases, and where its justice might be questioned. And let it not be said that we cannot make the law until the case to which it may apply shall have arisen and proved its necessity ; for, in this respect, we may question the experi- ence of Europe; we may see what cases have called for interference during the last five or six centuries, and be prepared to meet them when they shall occur in our own country. Another motive, which ought, we think, to induce the legislator to turn his attention to this subject is, that by so doing we will prevent the introduction of local usages and customs, which are at first introduced merely for conve- nience's sake, but which, after a while, assume the force of law, and tend to substitute, in the place of a wise, well digest- THE ART OF MINING. 37 ed, and universally applicable code of laws, a set of incohe- rent usages, often arbitrary and unjust, partial in their ap- plication, and not unfrequently, very contradictory; the his- tory of the origin of laws in all countries, and especially of that upon -mines in England, justifies us in our fears, that such would be the case in our own country, if the subject were totally neglected.* Those who are opposed to interference on the part of the legislature, generally answer that it is useless, because in- dividuals will always find it their interest to agree among themselves, and to work their mines, and to facilitate the working of those belonging to their neighbours ; but we be- lieve there are many cases, in which an individual may find it his private interest to oppose the general interests of so- ciety, and where he will do it if he can ; we shall only bring one instance in support of our opinion, and we shall take it from the extensive and celebrated coal mines of Newcastle on Tyne; it is a well known fact, admitted by all those who have visited these mines, that some of them are very benefi- cial to the proprietors; others barely pay at the present price ; while a third class cannot be worked without loss, un- der existing circumstances ; if the causes of this disparity in the profits be inquired into, they will not, nine times out of ten, be found to exist in the nature or abundance of the coal, nor in the nature of the adjoining rock, nor in the quantity of water in the works, but chiefly in the local situation of the mine. Some of them are situated upon the banks of the Tyne, in such a manner, that the coal brought out of the pit is immediately emptied into the boats or ships in the river ; * Since writing the above, we have found a passage in Mr. Schoolcraft's work on the mines of Missouri, which proves that the evil which we appre- hended is almost inseparable from mines, in a country where they are not re- gulated by law ; and that it has already unfortunately taken root in this country. The passage to which we allude runs thus: " Custom has establish- ed a number of laws among the miners, with regard to digging, which have a tendency to prevent disputes. Whenever a discovery is made, the person making it is entitled to claim the ground for twenty-five feet in every direc- tion from his pit, giving him fifty feet square, &c." (Schoolcraft's View of the Lead Mines of Missouri. New York, 1819. Page 107.) 38 CONSIDERATIONS UPON others are at a small distance, others again at a considera- ble distance from the river ; but all could be worked with ad- vantage, if the owners of the more distant mines were allowed to convey their coal to the river by the nearest route ; but this they are prevented from doing, the owners of the intervening property refusing them the passage, or requiring from them such an extravagant toll, as often amounts to a prohibition. We have seen instances, in which the owner of the coal was obliged to make a circuitous road of eight or ten miles, where the real distance, by tbe shortest direction, did not ex- ceed two or three miles. When we consider that tliese roads are all made roads, and inclined planes, it is impossible not to be struck with the great disadvantage under which mines at a distance from the river labour. The expense of making railways for such a distance, and the inconvenience of convey- ing so bulky an article as coal, and of so small a value com- pared to its bulk, deprive many owners of the reasonable profit which they ought to make, and prevent many others from working their mines. The effect is obvious ; the great competition is destroyed ; the public buys coal at an advanced price ; and the owners of KILLINGWORTH and WAULSEND alone are benefited by it. In making laws on mines, we must bear in mind, that they differ much from agricultural property, in this especially, that they are of a perishable nature ; that the mine which flourished during the last century, and offered great expec- tations to the miner, has been exhausted ; that it exists at pre- sent only in the remembrance of the great profits which it afforded, and in the immense chasms which it has left behind. As respects the interests of the miner, we may say, that they are closely connected with those of the manufacturer, in the same way that there is an analogy between mines and manufactures ; because they both have alike a tendency to convert the imperfect and native material into a new sub- stance, better adapted to the wants of man ; they change its form and its texture, its external and internal characters, and by a variety of manipulations, they produce a new body ; the interests of both are in a great measure linked together ; THE ART OF MINING. 39 both require the fostering hand of government, both demand the attention and protection of the rulers of the state, both tend to increase the national independence, and to create a new source of wealth and prosperity ; the miner extracts, from the bosom of the earth, the metals which the manufacturer con- verts into the tools and instruments used in daily life, and again receives from the latter those products of human ingenuity, without which, he could not continue his subterraneous works ; hoth the miner and the manufacturer can be greatly assisted, or much injured, by the transactions of the mer- chant ; both can assist him in his undertakings, and benefit him in his speculations; but both are at his mercy; he can bring a temporary ruin upon them, which must, however, al- ways recoil upon himself, and involve him in their common misfortunes. Hence, although the property of the miner may resemble that of the landholder, his interest connects him with the merchant and the manufacturer. Before we conclude this section, it remains for us to deter- mine the importance of mining, compared with other arts, and on this subject, we trust, a few words will suffice. It is evident that this art is of the first importance, since it may be considered as the basis of all other arts, inasmuch as these require the previous success of the miner, in order to provide for them their first implements, since society could not exist without the use of the metals, salts, and fuel, de- rived from mining ; since civilization is essentially connected with it, and must have originally been dependent upon it, for every improvement which it has made. Let us take any art we please, and inquire into the nature of the first materials it uses, the tools which it requires, the products which it consumes, the operations it performs ; let us then abstract every material produced by mining, &c. and let us see what will remain ; we believe we may safely aver, that it will be " stat nominis itmbra" 40 CONSIDERATIONS UPON SECTION THIRD. Of the actual state of Mining in Europe. Of the advantages which migJit accrue to the United States from the introduc- tion of this Jlrt. Of the obstacles which would intervene, and of the best course to be followed in order to remove them* The traveller who returns from distant countries, and who wishes to make known the result of his observations abroad, is seldom received by the public with indulgence. It is diffi- cult for him not to attack opinions already entertained by some of his readers. Hence, his observations are weighed with an unusual degree of severity. Every remark which he makes is closely examined, and he may indeed deem himself fortunate, if, in the review of his opinions, his intentions are respected, and his motives are not made the subject of scru- tiny. If the observations he makes are of a favourable na- ture, he is often suspected of wishing to assign to his travels an undeserved degree of importance. His praises are said to he lavished indiscriminately. The correctness of his judg- ment is questioned. If, on the contrary, he censures or ridi- cules, he is himself blamed, and not unfrequently by the very same class of readers who would have condemned his praises. He is represented as presumptuous, especially if he happen to be young ; his censures are considered as the mere effect of prejudice ; he is accused of being partial to one nation at the expense of another. We do not flatter ourselves that our remarks upon the ac- tual state of mining in Europe, will deserve or meet with a more favourable reception ; but we solicit the indulgence of our readers on this subject, as we believe it is the first at- tempt of the kind which has been made, and that the subject is new to the greater part of our fellow-citizens. We propose to examine, in the following pages, the state of the miner's art in France, Switzerland, Savoy, Germany, the Netherlands, Scotland, and England, as we have visited those countries, and have paid particular attention to the pre- THE ART OF MINING. 41 sent subject. We shall add a few remarks upon the mines of such other parts of Europe as we have not visited ourselves, but concerning which we have obtained correct accounts from fellow-travellers, upon whose accuracy we might depend. Mines of France. Until the end of the last century, the mines of France had been neglected : the government had either overlooked the subject, or been induced to suppose that the mineral wealth of that empire was but inconsiderable. The first attempt to improve the art was made, we believe, in 1740, when the government defrayed the expenses of two intelligent travellers, (Messrs. Jars and Duhamel,) who vi- sited the mines of Germany, Sweden, and England, and one of whom wrote a series of interesting memoirs on these mines, which were published after his death, and are considered, even at present, as among the most valuable text books on metallurgy.* A second expedition of the same nature was fitted out during the few years of comparative calm which marked the early part of the reign of Lewis XVI. All the travellers who shared this expedition have since died, except the distinguished author of the " Siderotechnia,"f a work which contains all that was known of the art of making iron and steel, up to the time of its publication. But the most im- portant step, taken in France, to improve the art of mining, was undoubtedly the establishment of a School of Mines. This school was founded a few years before the revolution broke out, but it was only brought into activity under the republican government, to which is also due the institution of a periodical work of great merit, exclusively devoted to this art, and to the sciences connected with it. The School of Mines was opened at first in Paris, and its original professors were among the most distinguished men of the time. After the conquest of Savoy, and its union with France, the school was removed to Moutiers, in the Alps, not far from Mont Blanc, and a neighbouring lead mine, of some importance, was placed at the disposal of the directors * Voyages Metallurgiques par M . Jars. f La Siderotechnie ou 1'art de traeter les minerals de fer, par J. H. Has- senfratz. Paris, 1812, 4 vols. 4to. 6 42 CONSIDERATIONS UPOW of the school. The object of this removal was to enable the students to become acquainted with the practical part of the art, at the same time that they studied its theory. This school was in reality a nursery of good miners. The number of engineers of mines which it has produced, and the celebri- ty which many of them have already acquired, while others have been employed in as useful, though less brilliant a ca- reer, arc the best proofs that can be given of the merits of this institution. On the return of the Bourbon dynasty to their paternal throne, the new acquisitions were given up, and Savoy re- turned to its ancient masters. The School of Mines was ne- cessarily broken up ; it was a short time after re-organized, and located in Paris. The situation in the metropolis was considered, in many respects, more advantageous, on account of the great facility which Paris affords over all cities, for the pursuit of science. The lectures are delivered by able professors, whose courses last during the winter season : an excellent chemical laboratory is annexed to the institution, in which the students are enabled to enter as deeply into the science of docimasy as their inclination prompts, or their ta- lents permit them. The school possesses, likewise, a su- perb collection of minerals, an excellent library, a cabinet of models of the machinery used in mines, &c. Teachers of drawing, and the German language, have been added to the school, and an instructor of the English language was also in contemplation, and has probably been already annexed to the institution. During the summer season, the students tra- A
