THE following work, it seems fair to apprise our readers, was originally prepared in England, and was designed for the children of that coun- try. But, with some alterations, which I shall make, it will be found equally adapted to chil- dren, in the United States, and to them, in this new dress, it is dedicated. They will find it an interesting and instruc- tive little volume. To heighten the interest of the work, I shall add a chapter about the mines which are found in various parts of the United States. From a perusal of the volume, they will be led to regard the globe upon which we dwell, with a deeper interest than perhaps they now 438849 6 INTRODUCTION. do. They look, no doubt, with pleasuie upon the fair and beautiful portions of the earth : they are delighted with the thousand beauties, which often cluster in a single landscape: its herbs its plants its flowers and trees its winding streams its bleating flocks its tidy cottages scattered here and there all conspire to fill the mind with pleasure, and to excite our admiration of the goodness and wisdom of the Author of our being. But this little volume will convey another lesson. It will carry its readers among the more unsightly portions of the earth lofty mountains deep precipices caverns and ex- cavations grotesque and shapeless works just the portions of the globe, which, at first view, would seem to be without interest or value. Yet even these will be found to be full of the riches and goodness of the Great Author of INTRODUCTION. 7 nature. They are unsightly, but not " neglect- ed spots." They contain articles important to our comfort and happiness. We shall find salt, and iron, and coal, with other minerals, without which, the common business of civilized life could not be conducted to say nothing of vari- ous medicines which administer to bur health, dug from the bowels of the earth nor of gold and silver important to commercial intercourse nor of the diamond and other gems, which serve to adorn and beautify our persons. They will learn, moreover, something of the process, by which the metals are separated from their ore, and of the toil and labor of thou- sands of our fellow-beings, doomed for life to delve in mines hundreds of feet below the sur- face of the earth shut out from most of the joys of society; forever excluded from the light of day. THE MINE SALT. CHESHIRE.* " THIS is something like !" exclaimed James, " Oh ! this is quite a fairy palace ! We seemed as if we were going out of the land of the living all the while we were coming hither : and now, surely, all I see is magic." Mr. Thompson was well pleased to find his * Cheshire is a county in the north-western part of England, lying in part on the Irish sea. It is about fifty miles long and twenty-five broad. Its capital is Chester, which lies on the river Dee, seventeen miles south from Liverpool, and one hundred and eighty-one north-west from London. Among other things, it abounds in excellent salt. Cheshire is also celebrated for the excellent quality of its cheese. 10 SALT MINES IN CHESHIRE. son thus interested and delighted. He had been at some trouble, and incurred some expense, to gain this sight foi him. They were now in the subterraneous regions of the salt mine, at North- wich;* and he had taken care to have the whole illuminated, according to a custom with the miners, when company visit the mines, who are willing to pay for this splendid exhibition. Numbers of the workmen, with each a light in his hand, had placed themselves in the various niches and corners of the mine. As the mine itself is a very large excavation, great pillars of the salt rock are left at various intervals, fif- teen, or even twenty -four feet in diameter, and as many in height ; by which means, besides a huge vaulted dome, a continuation of chambers, halls, and passages, appeared in view. As the * Northwich is situated at the union of the rivers Weaver and Dan ; eighteen miles east of Chester. THE DESCENT. 11 salt is like a white semi-transparent rock, every light glittered in a thousand places, exhibiting a great variety and intermixture of splendid colors: such as one might suppose a vast building would display, were the walls and arches encrusted with diamonds. As these excavations reach far under ground, some of the candles were evidently at a great distance, and gave the idea of an interminable labyrinth of brilliant apartments; although one vast amphitheatre, as the principal part, chiefly caught their attention. Here the floor was as level as any mason could have laid it ; the sides rose to a cupola in the centre, sup- ported by pillars, nearly pellucid, almost fifty feet high. This appeared the more astonishing to them, because their descent had been rather gloomy ; for they had been let down in a large tub, 12 ADMIRATION AND FEAR through a sort of deep well, about a hundred and fifty feet, and in rather an anxious mood. For the tub was only a rough one, the same that is used by the miners for raising the lumps of salt to the surface of the earth. It was some time before the fascination of the scene would allow the young philosopher to ask a single question, or notice any of the operations going on. He began at last to inquire, with a whole string of questions : " How deep are we in the earth? How far do these caverns reach? How much salt is obtained from hence every year ?" &,c. " It will take some time to answer all those questions," said his father ; " which can be done, too, more at our leisure, when we get above ground again. Meanwhile, let us observe some of their operations." When the extra lights were extinguished, OPERATIONS OF THE MINERS. 13 and only those remained which the workmen needed for their convenience, the place looked gloomy enough, especially after its recent bril- liant appearance. It was curious to w r atch the miners in their work, separating huge masses of the salt rock, with pickaxes ; and then, with heavy hammers, splitting them into smaller and more convenient portions. In some places, they bored the rock, and put into the deep hole, thus made, a quan- tity of gunpowder : this being fired, an explo- sion followed, w r hich usually separated several great blocks of the salt : these, as before, were broken, that they might be removed the more easily. These lumps, being carried to the spot under the mouth of the pit, were then drawn up to the surface of the earth, in the very tub in which James and his father had descended, and by which they also returned. 14 DEPTH OF MINES. " So, James, we are now above ground again. If the landscape below is the most curious, yet, upon the whole, the landscape above is the most pleasant ; is it not 1" " Yes, father ! I am glad I have seen th< mine ; but I am very glad now of the fresh air , and the bright sun, and the smiling landscape, with its variegated greens." " And now, some of your questions may be considered at leisure. You asked how deep we were below the surface of the earth 1 The roof of that grand cathedral, in which you were so much delighted just now, is about a hundred feet beneath us. But the depth of the several mines varies much. The salt rock seems to lie in vast beds, or strata. One of these had been worked for more than a hundred years, when another was discovered below it, but separated by a bed of hardened clay, or soft stone, be- NECESSITY OF PERSEVERANCE. 15 tween thirty and forty feet thick. This lower stratum is said to be very pure." "And how came they to find this, so deep in the earth, father? Who told them it was there V 9 "It was found, as we say, by accident. Persons were searching for coal, when they came to a solid mass of salt ; which has been to the proprietors an inexhaustible fund of wealth. It is well those w r ho were digging did not say, * This is not coal, let us give over, and try somewhere else.' It is well that, when they had digged for some time, they did not leave off in despair, and miss of this treasure. How much may be missed sometimes for want of perseverance ! And how much has been lost, through ignorance of the value of what has been actually found! It is said, that the bed of salt continues for a mile and a half, as mea- 16 SALT-WORKS IN CHESHIRE. sured one way, almost east and west, and about three quarters of a mile across it. The thick-, ness of the stratum of salt is from sixty to almost a hundred feet. Its upper parts are about forty feet below the level of the sea, and ninety feet below the surface on Which we stand. The thickness of the lower bed of salt has not been ascertained; but they have sunk above forty feet into it, without finding its bottom. In another place, three distinct beds have been discovered : one of them, four feet thick ; a second, twelve feet ; and the third has been penetrated above seventy feet ; but as no bottom has yet been found, we do not know how much deeper it is. "Salt is procured at several places here- abouts. They are mostly adjacent to the river Weever, which runs across Cheshire. The principal works are at Namptwich, Middle- SALT MINE AT NORTHWICH. B 18 ROCK-SALT. wich,* and Northwich : there are also some at Winsford, and other places; making nearly a dozen mines, now in full working. "Although the mine, into which we descend- ed, is one solid rock of salt, which may be dug into, and brougat up in lumps; yet, in many cases, the salt is found dissolved in springs of water. This is called brine, and must be ren- dered fit for use, by evaporating the water by boiling. As the water vanishes in steam, the salt crystallizes. Pumps of great power are in use at these brine springs, for bringing up the water from its deep caverns into large reservoirs ; though some of these springs are at no great depth. "Indeed, the rock-salt itself is not fit for the table, till it has been purified. This effect * Namptwich lies on the Weever twenty miles south-east from Chester. Middlewich is east of the latter place twenty-two miles. PURIFICATION OP THE BRINE. 19 is produced by dissolving it in water, and then, by heat, evaporating that water again, during which operation the impurities rise as a scum to the top, and are skimmed off. In order to facilitate this process, coagulable matter, such as eggs, &c. are mingled with the brine ; these quickly rise to the top, in the form of a crust, carrying every foulness up with them. Much of this purification is done on the spot ; but vast quantities of the pit salt are sent to Liver- pool and Bristol, to be there refined. Much is also sent, in its crude state, to the eastern side of the kingdom, where are long establish- ed salt-works, for supplying the adjacent coun- try. It has been calculated that above fifty thousand tons of salt are .extracted from the mines hereabouts, every year, supplying not only England, but also Ireland, the Baltic, and so the north of Europe, with this necessary 20 SALT MONEY. arthle. Large quantities also are annually sent to the United States. " Thus the proprietors gain money by it ; but in some countries money is made of it. It is thus precious in the central parts of Africa. The salt is formed into round flat cakes, which are stamped ; and these are taken as'ready money, in all the adjacent districts." " One would wonder how all the salt came here," said James. " True," replied the father : " men, who love to account for every thing, have guessed about it. Many have supposed that it has been formed by gradual deposits from the sea. Yet, if that were the case, how are we to ac- count for it, when found, as it is in some places, at considerable heights up mountains? In- deed, I do not know that sea water, if left to settle, will ever deposit its salt. Unless it ORIGIN OP SALT. 21 were over-saturated with it, how could it let it go, if heat were not applied to evaporate the water? If this salt had ever floated in the sea, it must, in its crystalization, have inclosed in it fish, or shells, or marine plants, of some sort; but we have no account of any such matters being found among it ; yet its power to preserve them, if once inclosed, cannot be doubted. " I am more inclined to suppose that masses of salt, like the rocks which we see around our coast, are part of the original creation, and were intended for great usefulness in the eco- nomy of our earthly habitation. Salt is ac- ceptable to man in every climate, and to many animals: sheep and horses are fond of it: pigeons are kept to their dove-cotes, by a lump of rock-salt being placed within their reach. In all nations, man is fond of it, and 22 SALT HELD SACRED. gives much to obtain it as a relish for his food. In ancient times, it was the symbol of friend- ship, and the test or bond of it. To have eaten a man's salt, was sufficient to bind the most furious passions. Thieves, who have broken into a house, with a design to rob and murder, on happening, accidentally, to taste the owner's salt, as they were exploring his premises, have been known immediately to withdraw ; not daring to violate what they were accustomed to consider as a binding engagement to do him no injury. "The manner in which salt is spread into countries far from the sea, shews a kind provi- sion for our wants ; and also militates against the notion of such masses having been produced from the saltness of the ocean. That it is found in high situations, has been hinted already. In Spain, near Cordova, is a hill, much higher than SALT EXTENSIVELY DISSEMINATED. 23 St. Paul's cathedral, composed of salt through its whole substance. Another, of equal size, is found in India. The mines of Saltsburgh, in Austria, are far above the level of the sea ; and the short duration of the Deluge cannot ac- count for such vast accumulations. Poland has immense mines of it, as we shall presently see. In the mountains of the Tyrol, it is found; also in Russia, at the Betski mines, great quantities are procured. In the southern parts of Asia Minor, it is in such plenty, and so hard, and the atmosphere is so dry, that it is used for building. It abounds in the northern parts of Libya; and is plentifully stored in the moun- tains of Peru. So widely spread as it is, so plenteously provided, it may fairly be supposed to be intended for important purposes, by Him w r ho knew what the wants of man would be ; and, indeed, what would be the occasions for it, in the globe, as an habitation." 24 SALTNESS OF THE OCEAN. " What, are these stores of salt of any use to the globe itself?" " Yes ; He who planned to give it so much sea, knew, that by saltness only, could the ocean be kept sweet. So far from supposing that these masses of salt were abstracted from the ocean, I think it" much more likely, that the saltness of the ocean is occasioned by stores of rock-salt at its bottom. We can trace these beds of saline substance upon the land, but the depths of the sea are hidden from us. There is nothing irrational in the supposition, that there may be also mountains and layers of salt intermingled with the mountains of rock, which form the bed of the sea. The continual agita- tion of the waters by the tides, will occasion a continual supply of the saline principle, if that be needful. The saltness of the sea is absolutely necessary, to preserve it from putre- SALTNESS OF THE OCEAN 2& faction. Accordingly, we find this saltness to be greater under the equator, than near the poles. At the equator, the great heat would tend more powerfully to engender putrescency, and there this grand preservative is most plenteously provided." SALT WORKS IN FRANCE. SEA SALT. "Axe is all the salt used by the nations of the earth, obtained from a few salt mines 1" "No. This is called rock-salt, or native salt; but much is obtained from the sea, by evaporation, which is termed bay-salt. In maritime countries, where the sun is powerful, this is the common mode by which salt is pro- cured. In France, especially, there are several salt-works of this kind, on the western coast, or Bay of Biscay. On some flat part of the coast, large but shallow pits are dug, gene- rally of three depths, and communicating with each other. Into the first, called the reservoir, the sea water is admitted at high tide, and penned in by means of floodgates. Being 28 METHOD OF OBTAINING SEA SALT. thus confined in a very shallow pit, the heat of the sun evaporates the watery parts rapidly. The residuum is then let into the second, or brine pond, which is shallower than the former, and on which the sun has therefore more power. The brine is afterwards let into the third pit, called the salt pan, where the water is not two inches deep. As the liquid evapo- rates, the salt, which cannot fly off, is left as a crust upon the sides of the pan ; this is gather- ed up every day, and placed in heaps, which are thatched over, to preserve them from the weather. This work occupies from May to August. If the season be favorable, the manu- facturers can thus obtain from the sea, in two or three weeks, salt enough for the whole kingdom ; but they also make much more, and export it to other nations. " The heat of the sun under the torrid zone is METHOD OF OBTAINING SEA SALT. 29 sufficient to evaporate pools of salt water; a large quantity of salt is thus produced, and may be easily collected. But the sun has scarcely power enougMn England for this process : yet, in Kent and Hampshire, thjre are pits of this kind, in which the water is so far evaporated by the sun, that a small degree of boiling finishes the process, and produces the salt. The brine is made during the hot months, and kept in large cisterns, to be boiled at leisure. The boiling is sometimes continued till the end of the year." SALT LAKES. SOME inland lakes and morasses are impreg nated with salt. A lake of this kind is found in Southern Africa, at a distance from the sea, and upon a height. The water which it re- ceives during the rainy season, becomes strong- ly impregnated with salt; in the succeeding hot weather, this water is evaporated ; and the salt is left at the bottom of the lake, two or three feet in depth. In the island of Ison- ming, near the coast of China, the earth is in some places so full of salt, that the natives dig it out, to the depth of a foot. This earth they carry to their salt-works, where they soak it in water in large shallow wooden vessels; and, by afterwards boiling the water, they obtain SAL1NA SALT-WORKS. 31 pure salt. In the western part of the State of New York, at a great distance from the sea, are numerous salt springs, some of them natural, and others made by boring deep through earth and rocks. The water thus obtained, is not so salt as that of the ocean, yet it is sufficiently strong to produce great quantities of salt, by boiling and by evaporation in the sun. The largest of these salt-works are at Salina, near Onondaga lake. They consist of several buildings, each containing eighteen or twenty iron boilers, of one hundred and twenty gallons capacity. These boilers are placed in two rows, and form what is called a " block." They are placed about three feet above the floor of the building, and under them is a large furnace, which is always heated to such a degree as to keep the water boiling. Pine wood is used for 32 SALINA SALT-WORKS. fuel, which creates a lively blaze, and is obtained plentifully and cheap, in the neighborhood. A large cistern, filled with water, is kept at Dne end of the building, and the water is con- veyed from this, through a hollow log, to the boilers, as fast as it boils away. After boiling for some time, there settles to the bottom a substance consisting of several earthy com- pounds. This is called " bittern," and is thrown away as useless. The boiling being continued, pure white salt forms in the boilers, which is taken out and placed in a store room, ready for barreling. Near the Erie canal, are a great number of vats, for evaporation of the water by heat of the sun. These vats rest upon small posts, driven into the ground. Some of these are six or seven hundred feet in length. They are about eigh- teen feet wide: They have coverings or roofs, SAL1NA SALT-WORKS. 33 in case of rain, which pass on and off by rol- lers. Some of the vats are deeper than others, and the deepest are first filled with water, from reservoirs, at hand. Here the water stands for some time, till it throws off a quantity of iron, or coloring matter, which appears on the surface in the shape of a pellicle, or thin skin. After this, the water is passed through hollow logs into the shallower vats, where it remains exposed to the sun ; and, after a while, deposits a quantity of sulphate and carbonate of lime. The salt now begins to appear, and crystalize on the surface. The water is drawn off again, into the vats, in which the salt is deposited as fast as the sun dries up the water. This is done in a longer or shorter time, according to the season, the dryness of the air, and the strength of the wind. After all the salt has 3 34 SALINA SALT-WORKS crystalized, it is shoveled into tubs, and drained of what water remains in it. It is then convey- ed in carts to the store-houses. Here are also works for making salt by steam. All the salt made by these methods, is very pure and white. It is commonly packed in barrels, containing five bushels, and is inspected and branded by an officer of the government. The quantity made here, is between one and two million bushels annually. SALT. POLAND. "BuT," said James, " what are the Polish salt mines, of which I have heard such wonders 1" " Several travellers have visited those mines, and have given us accounts of them ; perhaps the substance of their descriptions may afford us instruction and amusement. "The mines of Cracow, as they are fre- quently called, though they are indeed between six and eight miles from thence, are at a village named Wielitska, situated on a ridge of hills, adjoining the Carpathian mountains. The mode of descent into the mine, at the principal opening, is by means of hammocks, fastened to a great rope, by which the loads of salt are 36 PERILOUS DESCENT INTO THE MINE. drawn up. c We were let down gently/ says Mr. Coxe, * without any apprehension of dan- ger, although the depth was almost five hun- dred feet ;' (one quarter as high again as St. Paul's.) When they stepped out of their ham- mocks, they were not at their journey's end ; for they had yet to descend a slope, which in some places was very broad ; in others, the pathway was cut in the rock, into stairs, which were rather slippery, but, being wide, and glit- tering with the lights, which the visitors car- ried, had the appearance of a grand staircase in a palace. To some lower places, the de- scent was by ladders. Every visitor carried a light, as did each of the guides. The bril- liance occasioned hereby was considerable and peculiar. Mr. Wraxall describes one vast chamber, in which, he says, ' a thousand peo- ple might dine without inconvenience;' so SUBTERRANEOUS RESIDENCES. 37 large, indeed, that the flambeaux hardly en- abled him to discern the sides ; it seemed without limits. "When fairly descended into the mine, the traveller finds an underground country. There is no sun, nor sky ; but there are roads, with horses and carriages travelling in them; with multitudes of people, men, women, and chil- dren ; many are oorn tnere, and pass in those caverns great part of their lives. This is, however, voluntary on their parts; for those who choose to ascend in the intervals of labor, are not denied the opportunity of breathing the fresh air in the fields, and enjoying the ] ight of day. The horses, however, once taken down, continue there, and never return to day- light ; but are foddered and sleep in sheds cut in the salt rock. " Many of the chambers are very large, and 38 INTERIOR OF THE POLISH MINES. supported by pillars cf salt, left for the purpose ; some of them are thirty or forty, and some se- venty or eighty feet in height, without any sup- port except from the sides. The roads and gal- leries branch out in many directions. In some parts, they are very intricate ; so that persons, whose light has been accidentally extinguished, have perished, not being able to find their way back again. The length already excavated exceeds a mile, and the breadth is nearly half as much. How much larger the stratum of salt is, cannot be known: the depth already dug is above seven hundred feet. "Those who shew the mine, are careful to point out to strangers thfe various elegant cha- pels hewn in the solid salt rock. The altar- piece, the ornaments, a large crucifix, and sta- tues of the saints, are all cut out of the same glittering material ; and, when illuminated for LOT'S WIFE. 39 worship, have a splendid appearance. Mass is said in them (for they are Roman Catholics) on certain days in the year. "One statue is appropriate at least: it is a representation of Lot's wife, who was, you know, turned into a pillar of salt ; and it has been there so long, that most of the inhabit- ants believe it to be the very mass of salt formed on that occasion, w r ith herself in the midst of it ! "It seems remarkable, that all these places, though formed of salt, are very dry. There is one rivulet of water running through the mine, which is originally fresh, but becomes saltish, by running in the channel which it has worn in the salt rock. The rock is hewn with pick- axes; much after the same manner as in the English mines, in Cheshire. "There are other mines also in the neigh 40 PRODUCT OP THE POLISH SALT MINES. borhood, which have been wrought above six hundred years ; yet the laborers have not come to the extremity of the stratum of salt, in any direction. Between four and five hundred miners are employed in these w r orks ; and the whole number of men engaged in them is about seven hundred. Each continues at his work for eight hours ; and then, if he chooses, rises again to the surface. About six hundred thou- sand quintals, or sixty million pounds of salt have been annually raised from these mines. "While Poland had a king, he derived a considerable revenue from these mines ; it is said nearly 100,000 sterling,* every year. Since the partition of Poland by the neigh- boring potentates, they belong to the Emperor of Austria. His officers, however, have in their avarice outwitted themselves ; for, supposing * Nearly 450,000 dollars. AVARICE DEFEATED. 41 Poland must have this salt at any rate, they have raised the price of it exorbitantly. The King of Prussia, seizing this opportunity to en- rich his own subjects, imports great quantities of salt from other countries, and sends it into Poland, where it is sold at a cheaper rate than that which is dug up in the immediate vicinity of the consumers. The mines of Wielitska, therefore, now only supply a small space of country; and their productiveness in revenue is much diminished." " That serves the Emperor right, for his covetousness," said James. " Rather, perhaps," replied Mr. Thompson, " the Emperor himself knows nothing about it. His ministers, or commissioners, have thus cheated themselves : it is a very common mistake." D ENGLISH MINES. " How I should like to go abroad," said James, " and see all the mines in foreign coun- tries I" " That would be rather a long business," said Mr. Thompson ; " it would exceed your present holidays." " Oh yes, father ! But I should like it, I am sure. It would be so amusing, and so instruc- tive !" " Amusing came first, James, I believe, be- cause it lies uppermost in your mind. If that be your object, I should think enough might be found in England to fill up your time, and empty my pockets. Those are two bounda- ries to our pursuits, which have a very power- CURIOSITY ENHANCED BY DISTANCE. 43 ful influence in circumscribing our actual con- duct ; and they should have their influence in checking the wildness of our otherwise illimi- table desires." " Yes, father, I am sure I am very much obliged to you for bringing me such a journey as this ; and procuring me the sight of such wonderful places. Only, I suppose, there are more wonderful places still abroad ?" " There are very wonderful places abroad, no doubt ; but, why you should think they are more wonderful than those in England, I do not perceive. Though a mine be a little larger, or a little deeper in one country than in another ; yet the sight of one conveys as true an idea to the mind, as to the real nature of that sort of excavation, or that sort of mineral, as if you had seen twenty. You have been actually down into the salt mines at Northwich. The 44 ENGLISH MINES. color, the brilliancy of the salt, the mode of propping up the mine, the grandeur of the vast cavern, and the hazards of descending into such a place, and coming up again ; these and many other particulars you know, and will probably never forget." " That I shall not, I am sure, father. How I was astonished and surprised ! I never could have fancied what such a place was, in a thou- sand particulars, if I had not seen it myself." " And did not that actual inspection enable you to understand the accounts, which I com- piled for you, of the Polish salt mines at Wie- litska?" " Oh yes, father, I was quite interested in that account ; it was so curious ! And, as you say, I understood it clearly, because I remem- bered what I had seen." " Now England can furnish us with speci- EXCELLENCE OF ENGLISH MACHINERY. 45 mens of almost every sort of mine : and it has some peculiar to itself. A person, whose pro- fession was mineralogy, might find it worth while to visit even the mines of Potosi and of Kolyvan, though situated in different quarters of the world : but our object is only to obtain general knowledge, and, especially, to inform your mind on a point of so much importance. I am content to travel over England, therefore ; it holds all we want." " Yes, father : I do not wish, I am sure, to drag you either to Potosi or to (what do you call it ?) Kolyvan. I am very thankful for what you are doing ; and very much interested in what I am gaining." " There is one particular, in which England excels most countries ; that is, the machinery by which these grand works are conducted. The princely establishments of the various ma- 46 STEAM-ENGINES. nufactures, or mine proprietors, would not be found abroad. The scientific modes of opera- tion, too, are much better understood and practised with us. Not above two thirds of the silver is obtained from the ore at Potosi, because the work is performed in an ignorant and slovenly manner. Then, the power of machinery can nowhere be seen to so much advantage as here. In Cornwall, there are steam-engines in full work, each of a thousand horse power, capable of raising fifty million pounds of water through the space of a foot, with only the expense in fuel of one bushel of coals. Such is the mode by which the power of these gigantic machines are estimated. " We ought never to think of the vast trea- sures which Divine Providence has concealed in the bowels of the earth, without being reminded of the wisdom of the adorable Creator.

" Was he wise in that, James ; or ignorant and silly?" " I should have liked the diamond best. How it would have sparkled on mother's bo- som!" " Why, yes, James, the grain or two of barley would have been of no use to you. But remember, I was not asking for your judgment, or your wishes, in such a case ; but* rather your opinion of chanticleer." DIAMONDS. 49 "Then, I think," said James, "he was quite In the right, to prefer somewhat which was useful, to that which was merely ornamental, however splendid." " Keep that opinion in mind, James ; in the course of your life, it may save you many pounds. Yet, if nobody bought any thing but what is absolutely useful, many of the finer arts of life would be uncultivated, and the artists, who excel in them, must starve. So, let the dunghill cock look after barley ; neither he nor his pullets would be happier, nor indeed finer, for a diamond necklace. While, however, these bright gems are prized for ornament, (as that is the only use which can be made of them,) we may as well go on with our mining, and travel, by the help of books, into the countries where diamonds are found." 4 E 50 DIAMONDS. "Have we no diamond mines in England, papa?" " We have some very brilliant stones, in several places ; but no true diamonds. The Bristol stones, found about St. Vincent's rocks,* are in high repute, and deservedly, for their brilliancy. Cornish diamonds are also in esteem." "What! are real diamonds only found in the East Indies?" " For many ages, all our diamonds came from the East ; and, of course, they were very scarce. It was not till long after the dis- covery of America, that diamonds were found in Brazil. It has been remarked, that diamonds are found only in the torrid zone ; and also that the Brazil mines are at the same distance * Rocks on each side of the river Avon, about three miles below Bristol. BEAUTY OF THE DIAMOND. 51 from the equator on its southern side, as those of the East Indies are on its northern side. "The beauty of the diamond is greatest when you are unable to see it : that is, when it is so perfectly pellucid and clear, that the stone itself is not discerned, but only the bril- liant ray of light, which its polished surface reflects. " It is compared to a drop of perfectly clear spring water; and its denomination, when brightest, is a diamond of the first water. When compared to water by weight, the dia- mond is found to be three and a half times more heavy than the purest water. " The diamond mines in the kingdom of Golconda* have been long in the highest esteem. * Golconda is a province of Hindoostan. It is now known by the name of Hyderabad. Formerly the mines of Raolconda and Coulour employed many thousand men, but now they have ceased to be important, and hardly pay the expense of working them 52 RAOLCONDA MINE. A principal mine is at Raolconda, five days' journey from the city of Golconda : it was dis- covered in the beginning of the seventeenth century. The country is woody and rocky, approaching the ranges of hills which run across the province. In the crevices of the rocks, is sometimes found a sort of vein of sand, not more than an inch wide, and frequently not above half that size ; so that the miners are obliged to employ hooked irons, with which they rake out the earth and sand ; and among this loose stuff, the diamonds are found. They wash it, therefore, with great care, securing all the stones it contains. When the vein ceases, they split the rock still farther, by fire, and thus recover the vein, or find another ; for the vein will run, sometimes, nearly a quarter of a mile. "The value of these gems being very great, THE GREAT MOGUL'S DIAMOND. 53 and the secreting of them easy, the miners are made to work quite naked. There are also persons incessantly on the watch, to prevent their concealing them. With all this vigilance, however, they are sometimes deceived ; as the miners frequently swallow them, and thus get off with them without detection. " The famous diamond, belonging to the Great Mogul, was found in the neighborhood of Gani, or Coulour, which is seven days' jour- ney from Golconda. This mine was discovered, about a hundred and fifty years ago, by a pea- sant, who. was digging, and met with one dia- mond of twenty-five carats weight.* That of the * The value of diamonds is ascertained by their weight in carats, and this value increases in a very high ratio, according to their magnitude. For instance, a diamond weighing one carat might be worth about 8 ; while another of five carats would be worth 200 ; often carats, 800; and of twenty carats, 3,200. A carat is equal to four jeweller's grains, seven grains of which 54 THE GREAT MOGUL'S DIAMOND. Great Mogul weighed, before it was cut, almost eight hundred carats. It is not common to find are equal to six grains troy. To ascertain the value of wrought diamonds, the weight must be doubled, about half being supposed to be lost in the working. This sum must be multiplied into itself, and the product by two. Thus, to find the value of a diamond of 20 carats, multiply 20 by two the product is 40 this multiplied by itself, becomes 1600 and this multiplied by two, gives 3,200. In the possession of the Rajah of Mattan, in the island of Borneo, is a large diamond, shaped like an egg, with an indented hollow near the smaller end. It was found in that island about 80 years ago. It is said to be of the finest water, and weighs 367 carats, or more than two ounces and a quarter. Several years ago, the gover- nor of Batavia, desirous of purchasing this gem, sent a Mr. Stewart to the Rajah, authorizing him to offer for it 150,000 dollars, two large brigs of war, with their guns and ammunition, together with a certain number of great guns, and a quantity of powder and shot. The Rajah, however, refused to deprive his family of so valuable an hereditary possession 5 the Malays not only attaching to it the mi- raculous power of curing all diseases, but also believing that the for- tune of the family is sustained by its continuing in their possession. The sceptre of the Emperor of Russia is adorned with an oriental diamond about the size of a pigeon's egg, which weighs 195 carats.

It was afterwards transferred to a Jew for 1^000. Coming into the hands of a Greek merchant, he offered it for sale at Amsterdam, in 1766 ; and the Russian prince Orloff, bought it for the Empress Catharine for about 90,000 sterling, and an annuity of 4,000 during the life of the person who sold it. The Pitt or regent diamond, which was set in the handle of the sword of state of Buonaparte, is a brilliant of the most beautiful kind, and weighs 136 3-4 carats. It was brought from India by George Pitt, Esq. Governor of Bencoolen, in Sumatra, and was sold by him for 130,000 to the Regent Duke of Orleans, who placed it among the crown jewels of France.

"The importance of this mine appears in the number of persons employed in it, being frequently as many as sixty thousand. Their manner of operating is as follows : When, on examining the ground, they find a spot, which, to those accustomed to the search, appears likely to afford diamonds, they begin, in some place near at hand, to form a cistern or pool, with clay ; into this the women and children bring the earth, which the men have dug out of the appointed spot. Here, with water, they loosen the earth, breaking the clods, and permitting When the diamond is rubbed, it will attract bits of straw, hairs, feathers, and other small objects ; and if exposed to the rays of the sun, and immediately taken into a dark place, will appear lumim us.

When the miners come to water, they do not dig any deeper. The stony substances, which remain after the earthy particles are washed away, are carefully sifted, and then examined in a bright noonday light, which is reflected by the diamonds, and aids the research. Those who are accustomed to the business, are so ex- pert that they can discover the diamonds by the nice feeling of their fingers." " Then diamonds are always found by dig- ging 1" said James. "Not so fast, James; the term Mine, in most cases, seems to intimate a place under ground ; but this is not the case at Gani, for there, what is called a Mine, is of a quite dif- ferent nature. Indeed, it is, of all diamond PERSONS EMPLOYED. 59 mines, the mcst ancient. It is situate in the province of Bengal, amongst the sands of the river Goual, which runs into the Ganges. Being near the city of Soumelpour, it is often called by that name. From this spot, those small but splendid brilliants, called sparks, are procured. The violent rains, which increase the torrents from the mountains, bring down these precious gems. When these rains are pret- ty well over, that is, about the month of Decem- ber, or, possibly, not till January, if the waters do not get clear, the operation of searching for diamonds commences. Frequently, ten thou- sands persons from the city and its neighbor- hood assemble. To all ages and sexes, it is a sort of harvest; for the children can help. Those more accustomed to the search, examine the sands of the river, tracing them up to the mountains ; as it is near them that the larger 60 MODE OF SEARCH. diamonds are usually found. When they come to a place which they expect may be produc- tive, they separate a portion of the sands, by making a dam in the river, all around the spot, with faggots, stones, and clay. After emptying the water out of this inclosed por- tion, so as to leave the sands dry, they dig to the depth of half a yard, or more ; and carry what is dug up to a sort of cistern, walled in near at hand, as before. There they wash, and examine it carefully; trusting chiefly to the accuracy of their fingers, for discovering the precious pebbles. " The river Succudan, in the island of Borneo, is said to abound in diamonds; but strangers are not permitted to go thither. Now and then, however, by great cunning and caution, some very excellent stones have been obtained by the Dutch, and sold at Batavia." DIAMONDS. BRAZIL. " It wab not till 1 728, that the diamond was discovered in the Brazils, in South America. The manner of the discovery was thus : The negroes, who were condemned to search for gold, often found, among the sand and gravel, little bright stones, which, not being gold, they threw away. Some of the miners preserved a few of these stones, and shewed them to the governor. As he had been in the East Indies, he immediately suspected them to be diamonds, and sent them to Europe, where, after being cut and set, they proved to be diamonds of very fine water, though not equal to those oi Golconda. 62 BRAZIL DIAMONDS. "The place is called Cerro-do-Frio, and is situated to the north of Villa Rica.* The coun- try round about seems to be impregnated with iron ores; and the earth, among which dia- monds are found, is ferruginous to a conside- rable degree. The miners come to this bed of diamonds, as soon as they have removed the common vegetable soil Connection with iron ores seems to be general in all places where diamonds are found. " At the river Jigitonhonhaf is the most im- portant of the Brazilian mines. The course of * Villa Rica, to the north of which lies Cerro-do-Frio, is a con- siderable city of Brazil, situated one hundred and fifty miles north of Rio Janerio. It owes its origin to the rage for discovering gold mines. It was begun in 1711. It now retains but little of its former splendor, the mines in its neighborhood being much less productive than formerly. f This river runs north-east and flows into the Rio Grande, in lat. 16, 49'. MODE OF SEARCH. 63 the river is impeded by the miners, by a bank, raised by several thousand bags of sand. The pools thus formed are then pumped dry ; the mud of the river is washed away, and the earth, in which they expect to find diamonds, is dug out, and carried for washing and searching. This is done with considerable care and regu- larity. They erect a kind of shed, consisting of upright posts, supporting a thatched roof, to shelter the negroes while at work. This is about a hundred feet long, and almost half as wide. Through the middle of this shed, a cur- rent of water is made to flow, for washing the earth which they are about to search. On the sides of the stream are several wooden troughs, each about a yard wide ; and in every trough is a negro slave, with a rake contrived for the purpose. The earth to be examined is raked into the trough, in the quantity of about half 64 FINDING A DIAMOND. a bushel at a time ; and the water is suffered to run into each trough in a gentle current. Meanwhile, each negro, with his rake, spreads the earth about under this stream of water. It is raked again and again to the upper part of the trough, that it may be thoroughly washed ; which is known by the water running free from earthy particles. This effect is produced in about a quarter of an hour, if the whole be kept in constant motion. What now remains is a sort of gravel. The largest stones being of no value, are thrown away ; it is only among the smaller pebbles, that they are likely to find diamonds. Three overseers, seated in chairs, are appointed to watch the process, that the negroes may not secrete any for their own emolument. "When a negro discovers a diamond, he immediately stands upright and claps his REWARDS TO THE SLAVES. 65 hands, to give notice to the overseers : he then, holding it between his fore finger and thumb, presents it to them, and they immediately put it into a bowl of water, which is suspended from the roof. At the close of each day's labor, the bowl of diamonds is carried to the principal agent, who weighs and counts them, and enters in a book the weight and number of the day's research." "Poor negroes!" said James: "that is slaving for others without hope for them- selves!" "Not quite so," said his father. "It some- times happens that a negro finds a diamond of larger size than usual ; one that weighs seven- teen and a half carats ; and this is a happy day for him. He is directly crowned with a wreath of flowers, and led in gay procession to the proper magistrate, who immediately pays his 5 F 66 SUBSTANCE OF THE DIAMOND. owner the price of his liberty, and sets him free. He also receives a present of new clothes ; and may work on his own account, if he pleases. Smaller diamonds may gain re- wards, if they exceed certain fixed sizes. If a negro is suspected to have swallowed one, he is kept in close confinement till the fact can be ascertained. " When these treasures were first discover- ed in Brazil, diamonds were obtained in great plenty. The first fleet from thence brought so large a number, that orders were sent over from the Portuguese government, to decrease the number of hands employed in searching for them ; lest their abundance should make them quite common things, and, by lowering the price of those already brought over, spoil the trade. " It is very remarkable, that diamonds are of SUBSTANCE OF THE DIAMOND. 67 the same substance as charcoal ; a fact which, in the progress of your studies, you will be made acquainted with. To many persons, it must appear incredible, that the darkest and the brightest substances in nature should be so nearly allied." TIN. CORNWALL.

TIN MINES. 69 with their dense darkness or thin light foliage waving beneath the blue sky, in the most pic- turesque manner ; but in general, we must not among such scenery expect to find mines under ground. We are come in quest of sub-* terraneous treasures ; and these bleak unsightly moors promise well for our gratification." JAMES. "And how strong the wind was, father! Yet I saw in some of the valleys beautiful myrtles in full blossom; such as we can hardly rear in our greenhouses." "We are now near St. Austle: our imme- diate object are the Tin Mines at Polgooth, about two miles distant." "What a number of mines is here!" said James ; " if one may judge from the steam- engines." "Yes. There are between twenty and thirty now in use. The descent into them is called 70 A SHAFT. AN ADIT. n shaft; and above fifty shafts may be counted ; though they are not all worked at the present day." " What are those tall buildings for ? " " Those are the engine houses. Water is always very troublesome in these mines. Sometimes, the workmen pierce a passage from the bottom of the mine, sloping down- wards, if in a mountain, to the level country, to let the water off; this is called an adit, and is the occasional work of many years. But, frequently, the water is pumped out with steam-engines, at great labor and expense." The young traveller was surprised at seeing so many heaps around every mining house ; consisting of the ore as extracted, and thrown together. "Persons enter these mines, and come out again, as in most other mines, by the same A KIBBUT. A LODE. 71 conveyance that is used to bring up the ore ; here it is called a kibbut." The passing down in one of these was attended with a little anxiety. James almost fainted away with apprehension; but soon recovered himself, when, once at the bottom, he felt his feet. These kibbuts are raised and lowered by an apparatus at the top ; consisting of either a large winch, or a wheel and axle. In some places there are ladders, with landing-places at convenient distances. They had come upon the principal vein, or lode, as the miners call it ; and found it to be two yards thick. " In many places, the vein is, when first perceived, not above an inch thick, sometimes not above half an inch ; but as the miners follow it, it increases, and becomes more valuable. Towards the east, it has two 72 BLASTING THE ROCK. branches ; but it runs westward, seemingly, till it comes to the sea, at last. The miners have made their excavations to a full mile in length, but have not yet come to the end of it. They sometimes find pure lumps of metal, of twenty pounds weight. " They have to blast the solid rock with gun- powder, in order to get at the ore conveniently. Frequently, the vein ceases abruptly, as if it had been suddenly snapped off; when this is the case, experienced miners will soon discover the disconnected part, and proceed again in their lucrative excavations. The continuation is usually found on one side, and at no great distance from the fracture." "And how deep in the earth are we now?" said James to one of the miners. "Oh, Meastur, summer about five score fathom, or more, just here."

On examining the steam-engine, they found that every stroke drew up water thirty feet deep in the piston, which was fifteen inches in diameter ; so that the discharge was wonderful. The expense of such establishments must be very great ; but so are the profits. This mine has, in some years, cleared twenty thousand pounds. EXPLANATION OP THE STEAM-ENGINE. A. The furnace. B.

There are some, called stream works, especially on St. Austle's Moor. It should seem that all the streams, which run from the adjacent hills and settle in this valley, bring with them lumps of tin ore, larger or 76 STREAM WORKS AT PAR. smaller, and have done so for ages. The soil, also, brought down by the waters, has settled in the valley, till it has accumulated to the depth of from twelve to twenty feet. On dig- ging into this artificial soil, several layers of earth, clay, and gravel, are found ; then a stra- tum of stones, which, being heaviest, have sunk lowest, while the whole was moist and soft. Beneath these successive layers are other stones, which are the ores of tin; these are easily known by their being very heavy ; some are lumps, as big as one's fist ; some are almost as small as fine sand. Below these, are solid rocks ; in which is no tin. The tin obtained from these stones is reckoned very pure, and is in considerable plenty, having but a small proDortion of refuse. " These stream works extend to Par. There the incumbent earth and sand form a stratum STREAM-WORKS NEAR TRURO. 77 seventy feet deep. The miners bring streams of water to act upon it, with considerable vio- lence, in order to wash the sand away ; yet the pebbles are left at the bottom of the several channels. "There are several mines of less conse- quence, though well worth the working, as at Gwennap, Illogan, Trevennen, &c. ; but seeing one is essentially seeing all. These smaller works employ from a hundred to a hundred and fifty miners at each of them. One might reckon up nearly two hundred of those smaller concerns. "The stream-works near Truro are said to yield eight thousand pounds a year profit. "These tin works are of different sorts, according as the tin is found ; sometimes it is obtained in the form of stones, very heavy, and full of metal ; but more often the tin is mingled 78 MARKING AND ASSAYING. with earthy matter, almost as hard as stone, and of a bluish or grayish appearance. " When the ore is brought up to the surface of the earth, it is thrown into heaps Here multitudes of the poor find employment in breaking it \vith hammers. In this broken state it is carried to the stamping-mill, where it is pounded. In order to this, it is turned into a sloping trough, and a small stream of water assists it in sliding down into the case wherein the lifters work. These are pieces of timber, shod with large masses of iron: they are raised and let fall again, by a water- wheel. The ore is repeatedly washed before it is brought for melting. When melted, it runs into large oblong moulds, each of which contains about three hundred weight of pure tin. It must now be conveyed to some one of the Stannary towns, to be marked and BREAKING TIN ORE. 80 STANNARY LAWS. assayed, or, as they call it there, coined. This is done by officers appointed by the Duke of Cornwall. They cut off a corner, and then stamp it with the proper seal, and the name of the melter. This gives assurance to the purchaser that it is pure tin, and tells all whom it may concern, that the duty has been paid. The duty paid to the Duke is four shillings for every hundred weight. The Prince of Wales is Duke of Cornwall ; and his revenue, from this source, has been calculated at thirty thou- sand pounds a year. " There are laws, called Stannary laws, by which all these mines are regulated. Every case relating to them must be tried before their own courts, and cannot ie removed elsewhere. "If a person suspects tin may be found in any certain spot of his own estate, he must CAPTAIN OF THE MINE. 81 obtain leave of the lord, before he can work it. If the spot be on some unoccupied moor, he may bound it ; that is, make a pit at each of the four corners of the plot. No one can then operate on that piece of ground without leave from him, as well as from the lord of the soil. "The share which the lord of the soil claims, called technically his dish, is about one sixth or one eighth part, free of all charges. " The miners are not paid by the day, but by a share of the produce. This makes them careful to obtain all they can from the lode, and in as little time as possible. " The whole conduct of the mine, and of the miner, is under one person called the Captain of the Mine. Besides knowing the proper methods of getting the ore out of the rock, he must have some knowledge of Mechanics, 6 82 ANTIQUITY OP THE Algebra, and Geometry. He would be es- teemed unfit for his office, if he could not, at any time, point out, upon the surface of the earth, the spot exactly over where the miners are operating ; so that if it should be necessary to sink another shaft, he may conduct it per- pendicularly down to the very spot where it is wished for; though at a great depth in the earth, and notwithstanding all the windings of the mine below." James was much surprised to find so much knowledge, as, on several occasions, he met with in persons whom, from their dress and laborious occupation, he had supposed to be very ignorant. He several times wished he had his own geometrical problems more ready for use. " Now, father, when we have seen any En- glish mine, you tell me about similar mines in BRITISH TIN MINES. 83 other countries. Where are the other tin mines 1" " We shall not have much to say about tin mines in other countries, James ; for there are only three places in Europe, where tin has been found : in Germany, in the mountains of Saxony ; in Spain, near Portugal ; and, the best of them all, those which we have now seen in Cornwall. In some parts of Asia, and in South America, it has been discovered ; but not much of it has become an object of com- merce, like ours." "Some of the men said these mines had been worked above two thousand years; is that true, father?" " It is very likely to be true, James : for the Phoenicians are said to have traded hither for tin, more than five hundred years before the Christian aera. That is, in the reign of Zede- 34 BRITISH TIN MINES. kiah, before the Jews were taken captive to Babylon. If so, that is more than two thou- sand three hundred years ago; and the man may be right. " Some tin has been found in the island of JBanca, near Sumatra, of which the Dutch have made their advantage. Some is found in the province of Nanking, in China; but it cannot be in any great quantity, because, every year, the English export tin to China, to a con- siderable amount, from these mines in Corn- wall." COPPER. CORNWALL. "What are those odd looking horses, father: What are they loaded with ? And whither are they going?" " They are mules," said Mr. Thompson. "A mule is an animal between a horse and an ass. They are preferred, as being extremely sure- footed. Each of them has, you see, a sort of wooden saddle, on which is laid a couple of dirty, dark looking sacks. These are filled with copper ore, which is to be conveyed to the sea- side, in order to be sent to Swansea, in Wales, where it will be smelted, and cast into moulds, ready for market. TRAIN OP MULE6 OEK DOLGOOTH COPPER MINE. 87 "Having seen the tin mines of Cornwall," continued the father, " we may as well look at the copper mines, now ; for Cornwall is famous for that valuable product, as well as for tin. " Possibly the most important of these sub- terraneous treasures is at Dolgooth. Here again we meet with excavations a mile in length. "Beneath, the earth is scooped and hol- lowed in every direction, almost like a honey- comb, only with less regularity." They had to descend above twelve hundred feet to the bottom: and then might choose almost any direction, which way soever they might prefer to go. "Many steam-engines are employed here: some in bringing up the ore and the rub- bish; and several in pumping out the water, to drain the mines. Some of these are so 88 IMPORTANCE OF large, as to be denominated of a thousand horse power. " Such expenses as are incurred by candles, tools, and gunpowder, belong to the miners, who provide for themselves. They are repaid by a certain proportion of the copper raised from the mine, when it is actually sold; so that they are personally benefited by working the mine well. " We may judge of the importance of these mines of copper, when we understand that the persons in actual employ about them, of all descriptions, aged and children, women and men, are above sixteen hundred. The expens- es are not less than fifteen or twenty thousand pounds a year. But then the produce is pro- portionably large, amounting, frequently, to be- tween seventy and eighty thousand a year, in money. THE COPPER MINES. b9 " Perhaps we should not reckon much amiss, were we to suppose one hundred thousand persons employed in this one country, in bringing these treasures from the bowels of the earth." "Do they ever find silver or gold in these mines 1" inquired James. " Yes, sometimes ; but not in any great quantities. Grains of gold have been found, like fine sand ; and small quantities of silver. Although as much as was worth two thousand pounds has been obtained near Gwinear, yet the expenses of procuring it were so great, that there was not profit to the proprie- tors, sufficient to make it worth while to work them. They have therefore been dis- continued. " Much lapis calaminaris is found, too, inter- mingled ; this yields zinc. A mixture of copper H 90 COMPOSITION OP BRASS. and zinc makes brass ; as a mixture of copper and tin forms bell-metal. " We must not forget an ore called Mundic, or, sometimes, Marcasite. This was long neg- lected, as useless. Early in the last century, Sir Gilbert Clark found out a method of pro- ducing from it very fine copper, to the value of nearly two hundred thousand pounds per annum ; so well employed is scientific know- ledge, and so prodigal are the ignorant! If education cost much, yet it is a means to save a great deal, by teaching us the value of many things, which, through ignorance of their worth, we might pass by, or throw away ; and giving such general knowledge as enables a man to take advantage of all that Providence brings under his notice.

"It was long supposed that tin was not worth working, when more than three hundred feet below the surface of the earth: but the best mines now worked go much deeper ; some even to nine hundred feet. "The tin mines were wrought long before those of copper were discovered. There was, indeed, a stony substance, which the miner found troublesome, and, thinking it useless, he threw it away ; this was called poder ; and he 92 VALUE OF PODER. even abandoned the mine, when this was too plentiful. This arose from ignorance. About the year 1735, a Mr. Coster, of Bristol, who had better skill in mineralogy, observing the heaps of this substance, which were thrown away, engaged to take it out of their way, and contracted for it at a low price. He soon found how to extract copper from it ; and made so much use of his better knowledge, as to gain a fortune from what may be called the refuse of their ignorance. Be careful how you throw any thing away ; or, rather, endeavor to gain knowledge, in every varied shape, that you may not be liable to throw away any thing which may be really valuable." COPPER. ANGLESEA.* ALTHOUGH it was some time after their leaving Cornwall, that they visited the famous copper mines in the Parys Mountain, in Angle- sea; yet it may be convenient to our readers, if we put all of a sort together. We shall, there- fore, proceed to relate what was found there worthy of notice, and exhibit the nature and importance of the mine. * Anglesea is an island twenty-four miles long by seventeen broad, situated in the Irish Sea, on the north-western coast of "Wales. The Parys Mountain is nine miles in length, and half as much in breadth, apparently wild, waste, and barren in the extreme, but containing a bed of copper ore which is supposed to be the largest in the world. 94 PARYS COPPER MINE. In most mines, we have to descend deep into the bowels of the earth, and traverse its gloomy caverns by the flickering light of a candle, or a link, which threatens every mo- ment to leave us in darkness. The miners work by a mere glimmer, and pass to and fro almost in the dark. But the Parys Mountain mine is quife different; it is open to daylight, and permits the sun and the fresh breezes to purify the atmosphere, and carry off the noxious vapors. Not but the air is still very offensive, in the direction of the wind especially, from the suffocating fumes of copper, which arise on all sides. The whole country around, for miles, is desolate from the effects of these exhalations. The first sight of the hill is dreary enough ; being an assemblage of enormous rocks, hide- DISCOVERY OP THE MINE. 95 ously piled on each other, of the species called quartz. On ascending towards the top, the prospect opens of a huge bason, nearly half a mile across, or a good mile in circumference. Persons had been searching here for mineral treasures for a long while, and at considerable expense : they were on the point of giving up the search as fruitless; when, unexpectedly, in the year 1768, they met with a large mass of copper ore. This gave them new spirit for fresh exertions. The mines have been wrought ever since, to great profit ; sometimes fifteen hundred men have been employed in them, who, with their families, may be reck- oned as seven or eight thousand souls, whose living entirely depends on this produce. This hollow is, on one side, filled with water ; over which, it is said, a bird is never 96 DRAWING UP THE ORE. seen to fly. It is likely, that the fumes are so offensive, that they are disgusted, and so kept from danger. "What a prospect!" said James; "what a dreary prospect ! And see, father, what those men are standing on! It is enough to make one giddy to look at them." " O ! I see ; they are standing on scaffold- ings, projecting a great way from the tops of the rock ; and there is a windlass at the end of each, by which I suppose they draw up yes, there is one going they draw up their baskets, full of ore, from the bottom of the pits. "The rock is, first of all, split, by being blasted with gunpowder, as in most mines. It is said, that eight tons of gunpowder are thus used in these mines, every year. The ore, so obtained in large masses from the rock, is PARYS MINES. ANGLESEA COPPER. 98 OPERATIONS ON THE ORE. broken with great hammers into smaller pieces, before it is drawn up to the surface of the earth." The fumes most discernible were the sul- phureous; for the ore is much loaded with sulphur, and it is driven out by fire. Heaps of copper ore were seen around, smoking and fuming to the great annoyance of all who travel that way. The ore, when thus far purified, is sent to places where coals are plentiful, in order to be smelted, and run into moulds, fit for commerce. In this state they are called cakes, and in some places salmon. " This is an amazing mass of metallic ore ; perhaps there is not such another in the world. It has been now worked upwards of sixty years ; and seems likely to last a long time, with an equally plentiful supply. AN APPARENT TRANSMUTATION. 99 " In many places there are waters, in smaller or larger pools, fully impregnated with particles of pure copper ; indeed, the purest copper is obtained from these waters." James was eager to know how this was done ; and was told that the water contained a considerable portion of sulphuric acid, or what he would call oil of vitriol, united with copper; in other words, the water contained a quantity of blue copperas, called by chemists sulphate of copper. And farther, that a laborer, once leaving his iron spade, accidentally, in some water of this kind, found it, after a few weeks, so covered with a coat of copper, that he firmly believed the iron had been trans- muted into copper. "Now the process of obtaining the copper from such water, is simply thus : the water is pumped up into pits, made on purpose for 100 VIRGIN COPPER. the operation. Then plates or pieces of iron are thrown into them, and left for a time. The acid, before alluded to, which had dissolved the copper, and held it in solution, having a stronger desire for iron, (a stronger affinity, chemists call it,) seizes on that metal, and lets go the infinitely small particles of copper, which it contained, and they fasten themselves on the iron ; so that the common people say, and believe, the iron has been changed into copper. By those who know better, these pieces of iron are occasionally taken out of the water, and carefully scraped, to get the copper off them ; after which, they are again thrown into the pits, till at length they dissolve, and are held suspended in the water, while the copper is precipitated or thrown to the bottom. The mud is then raked out and put into a furnace, to melt the copper and free it from the ANNIVERSARY aEEB3?A.TIQBT.- . , 101 sediment. Copper so procured is very fine, and much purer than that which is obtained by smelting. It is equal to what is called virgin copper; a name given to lumps, or branches, of pure, solid metal, which are now and then found. Both sell at a higher price than smelted copper. " Although it is only about sixty years ago, that we say this mass of copper ore was disco- vered, we ought rather to call it a re-discovery, as evident traces are met with continually, of this mine having been worked many ages before ; when all the knowledge in these mat- ters amounted to heating the rocks violently by fire, and then suddenly deluging them with water; which occasioned them to crack, and scale off, so as to enable the workmen to break them in pieces, fit for smelting." Had our travellers happened to come hither 102 M7i\E AT ECTON HILL. in March, they would have found all parties in high holy day mood ; for in that month the mine was discovered; and the anniversary is kept with great glee and joviality, down to the present time. Their attention was excited by noticing a stratum of yellowish clay, which felt considera- bly greasy to the touch. This appeared to be very near the top, not a yard below the sur- face. The stratum itself was indeed, in some places, ten or twelve feet thick ; in others not more than three feet. This, it seems, is well stored with the ore of lead ; and this lead has in.it a tolerable proportion of silver; as much as four pounds of silver in a ton of lead. When they were at Ecton Hill, or Acton Hill, in Derbyshire, they found another copper mine, but of a peculiar kind, nothing like WICKLOW AND NORWAY MINES. 103 it having been yet discovered in the whole world. Other mines run to a great length, or branch out in various directions ; but this sinks down perpendicularly, widening as it descends, continually, in the form of a cone. It is situated near the river Dove, and was discovered about the year 1740. Those who first sought here for ore, spent thirteen thou- sand pounds, without gaining any benefit. They dug six hundred feet in depth, before they came to the ore. Then they found a rich supply ; and a supply which increases as they descend. The works are four hun- dred and fifty feet below the bed of the river. It is the deepest mine in the British islands. On the opposite side of the hill is an excellent lead mine. "Before we go absolutely abroad, we will just step over to our sister isle. At Wicklow, 104 RORAAS COPPER MINE. in Ireland, are copper mines ; those especially at Cronebane, are considerable in their pro- duce. " Copper is obtained in this kingdom too, by immersing iron in the water of the mines, by which process the finest sort is procured. "In the Wicklow lead mines, much silver is found, to the amount of one part in thirty. Lead ore is very frequently connected with silver. "Norway has mines of copper. That at Roraas, in the province of Drontheim, was discovered by a Laplander, travelling with his reindeer, in 1644. In some years above six hundred tons of copper have been drawn from it; but some of the veins have, of late years, become deteriorated in quality, and diminished in quantity. Three hundred thousand tons of charcoal are consumed an- RORAAS COPPER MINE. 105 nually, in smelting the ore.

" The copper mines at Fahlun are not only the best in Sweden, but they are among the best in the world. Swedish copper ranks high in the market : all our manufacturers are aware of its excellence. "Fahlun is situated in a hilly country, among dreary rocks, and also between two lakes of considerable size. "Very ancient records speak of this mine as having been famous in remote ages ; so that it is impossible now to relate the story of its discovery. "The mouth, or entrance, of the mine is very large, perhaps a thousand or tw r elve hundred feet in width : it is a vast chasm among the rocks, which is continually enlarging as the parts around keep falling. The descent 108 APPEARANCE OF THE MINERS. is rather hazardous, down several flights of wooden stairs to the first gallery ; then it becomes so easy, that, though it consists of steps cut in the rock, the horses, who are used to it, can pass up and down them, as they go and come in bringing up the ore. " The miners have no clothing on their bodies, or arms; their naked appearance gives a sort of awfulness to the scene, which is heightened by the lights, which every one carries about in his hand, consisting of small slips of wood, made into a bundle, and lighted. "The subterraneous galleries penetrate far into the bowels of the earth; they are from six to ten feet high, and of varying widths. Measuring the chasm from top to bottom, we find it above a thousand feet; and from the entrance of the gallery to its lowest part, it is seven hundred feet more. It is true. PERILOUS DESCENT TO THE MINES. 109 there is a tolerably commodious staircase for a long way; then we come to a deep pit, into which the descent is by a wooden lad- der ; after this there is an iron ladder, hanging loose against the sides of the pit ; then a wooden ladder again, reaching as far as one can go ; as the bottom of the pit is full of water. It takes up four hours to pay this visit to the bottom of the mine : and the coming up again, such a length of way, and by such means, is peculiarly dangerous and fatiguing. " The modes of operating in this mine are very similar to those in other mines. The rock is blasted with gunpowder ; and the dissevered masses are broken smaller with hammers. The ore is roasted, in order to 'drive off the sulphur, and the rest is smelted for sale. But this roasting and smelting are 110 SUPERIORITY OF SWEDISH COPPER. repeated several times, in order to bring the copper to that high state of purity for which Swedish copper is in such great repute. "Much copper is also obtained here, by the now common process of steeping iron in the waters of the mine. "Twelve hundred workmen are usually employed here ; one half of them as miners in the bowels of the earth; the other half in roasting, smelting, and other necessary operations belonging to the concern. "Copper melts very readily. It is drawn out into fine wire. Screws, and nails, and utensils for domestic purposes, are made of it. The bottoms and sides of ships are co- vered with it, to prevent their decaying, or being injured by insects. Mixed in proper quantities with zinc, it produces brass of a beautiful color." IRON FOREST OF DEAN.* have come some way through this Forest of Dean," said James; "I think the man was right, who said it was twenty miles long; though the ostler said that was its length formerly; and there is not so much forest now as there used to be." " In Queen Elizabeth's time, when the Spanish Armada was sent over, the invaders * This forest lies in the county of Gloucester, between the river Severn and the county of Monmouth. It once contained thirty thousand acres of land, with an abundance of fine timber. The wood has been much diminished by the forges, which are em- ployed in smelting the iron. 112 IMPORTANCE OF IRON. were expressly commanded to destroy the Forest of Dean, because the best oak for our shipping grew there. However, Sir Fran- cis Drake, and our brave admirals and sailors, would not let them execute their orders; for they defeated and dispersed their boasted invincible fleet." As it grew dusk, their attention was at- tracted by symptoms of their approach to the mining district ; the forges were blazing and smoking on every side. " Mines of iron are here, providentially, accompanied by mines of coal ; these make the former of double value, because the iron ore can be smelted on the spot: indeed, they are generally placed in the same neigh- borhood. " Iron is never found pure, as are sometimes copper, silver, and even gold. It is, however, SMELTING THE ORE. 113 plentifully dispersed about our globe, and is one of its greatest natural gifts. Where there is no iron, there cannot be efficient tools ; no arts can be carried on to any great extent, neither can the sciences exist, nor the cultiva- tion of the mind take place. The use of iron is the first step towards civilization, in all countries. Where this is unknown, the peo- ple are savages, and so they must remain. " The rusty brown stones, which constitute the ore of iron, do not seem to promise much of value, either as to beauty or usefulness. But man has found out the means of making them of great importance, by drawing from them that most useful substance, iron; and again refining that into the most elegant articles of steel. "The brown stones must first be roasted; this calcination brings them into a state which 8 K 114 THE SMELTING FURNACE. renders their fusion a much easier and more certain operation, by expelling the sulphur or arsenic which abounds in the mineral state. " It requires some instruction in the nature of the smelting furnace, to understand the process. The building, externally, represents a huge cone of masonry ; for the weight to be sustained, and the force of the fire to be resisted, are both very great. Interiorly, this cone forms a round cavity, narrowest at top; the bottom of which holds the ore to be smelted. Some notion may be formed of the greatness of the operation, when we find this hollow to be thirty feet in height, and twelve in diameter at the widest part, or towards the bottom ; the inside being somewhat of the shape of an egg, with the largest end down- wards. The very top, or mouth, is shaped like a funnel, so that whatever is thrown in THE BLAST FURNACE. 115 readily descends into the body of the furnace. It is at this mouth that the laborers feed the furnace ; by throwing in, alternately, baskets of fuel, and baskets of ore. The whole height of the furnace, with its fireplace, is above fifty feet. "In former times, the only fuel used was charcoal; of which the consumption was so great, that our forests, which were decreasing very fast, could not supply the demand: in- deed, the scarcity, and the increased price, threatened to destroy the whole iron trade. After many unsuccessful attempts, the ma- nagers contrived to conduct the operation with pitcoal. The difficulty was, to obtain a heat sufficient for fusing the metal. Iron may be easily made red-hot, but the heat must be raised far beyond that, to melt it, so that it may run into a mould. This effect is now 116 THE BLAST FURNACE. produced by what is called a blast furnace, a wonderful contrivance, which has given a power of operation, and, of course, a value, to our mines, of incalculable extent. " We all know that the operation of a pair of bellows will greatly increase the intensity of a fire ; but what man, or set of men, could blow such bellows as should be applied to so great a mass of this ? For some time, huge bellows were employed, of the usual shape, and worked by a water wheel; but a much more powerful blast is now obtained, by a piston working in a cylinder, upon the prin- ciple of a common pump, in which the rod, with its bulby head, commonly called the sucker, because it seems to suck up the water from the well, is the piston ; and the tube in which it works is the cylinder. The only difference in effect, is, that the machine I am THE BLAST FURNACE. 117 now speaking of, throws out air instead of water. As the piston rises, a valve is opened, through which the air rushes into the cylinder ; and this air, by the descent of the piston, which closes the valve, is forced into the pipes, which convey it to the furnace. By this means, when the piston is set in motion by a steam-engine, the blast is almost incon- ceivably increased in power, and the air is driven into the furnace in a very condensed state, which is a great advantage. The cylin- der is eight feet in diameter, and eight feet high; the stroke of the piston is seven feet. But, as the orifices, or nose pipes, through which all this mass of air is at every stroke forced into the furnace, are only two or three inches in diameter, the violence of the blast may be supposed, though it can hardly be described. Its effect, when driven into the 118 PIG IRON. furnace, is wonderful; but it is not let in till the matters in the furnace are as hot as common fire can make them ; for till then it would do more harm than good, by retarding the operation. When this powerful blasting begins, the roaring of the furnace becomes tremendous ; the effect upon the metal is irresistible; and it is continued for about two hours.

" After the lava, or melted metal, has begun to run for some little time, it is let out into channels formed in sand, which lead it into THE BLAST FURNACE. 120 WHITRIGS IRON MINES. hollows, formed also in sand, in which it settles and cools. It is then called pig iron. " Iron ore is found in many parts of Britain ; and as the nature of the mines, and other operations by which the iron stone is reduced to pure iron, are very similar, thay need not be repeated at every mine. "At Whitrigs, near Ulverstone, in Lanca- shire, are iron mines, which have been wrought four hundred years, and yet seem to be inex- haustible. There are immense beds of ore, from thirty to fifty feet thick, and from a hun- dred to a hundred and twenty wide. The ore is red and greasy ; those who are engaged in the works shew the color on themselves very powerfully. Sometimes, two , hundred tons are raised in a week ; the metal produced from it is more than half the weight. Here the smelting is effected with charcoal; of IRON MINES IN SCOTLAND. 121 which vast quantities are burned in the vici- nity. " There are mines of iron in Scotland ; and much of the ore is smelted at the Carron* founderies, where are twenty furnaces, which consume two hundred tons of coal every week. The place which, a few years ago, was a wild heath, is now a considerable town ; as two thousand workmen are employed at the works. The machinery is of the most excellent kind, and wonderful in its opera- tions." * Carron is situated twenty-six miles north-west of Edinburgh. The carronade, a kind of short ship-gun, derives its name from having been first made here L IRON. RUSSIA. "WE have great quantities of iron from Russia. The principal mines are situated in the Uralian mountains, which, towards the northern part of the eastern border, separate Russia from her Asiatic dominions. " Here are above a hundred founderies ; more than half of these are for iron, and the remainder for copper. The peasants, as is common in Russia, belong to the estate, whether private persons own the land, or the sovereign. Almost a hundred thousand of them work in these mines, at the will of their several lords. RUSSIAN MINES. 123 "They raise, upon an average, nearly one hundred thousand tons weight of iron annu- ally; part of this descends, by the Wolga, to the eastern provinces ; and the greater part of it is towed, through rivers and canals, to Petersburgh." TRON. SWEDEN. " BY all the feelings which belong to liberty, and associate with the name of Gustavus Vasa, the deliverer of Sweden, we must pay a visit to the mountains of Dalecarlia, where he was hid so long, and whose hardy sons enabled him to resist the tyrannical Danish King, Christian II. Among those mountains, and in those mines, he wrought as a common laborer, till an opportunity occurred for his declaring himself, and engaging the miners on his side. The inhabitants of those dis- tricts have a great veneration for his memory, to this day/ 5 SWEDISH MINERS. 125 " I suppose," said James, " our visit, as usual, is to be paid by means of your library, while we sit by the fireside." "It will be most convenient. We shall employ several travellers ; we have only to fancy, or, as children say, make believe, that we have sent Messieurs So-and-so to gain information, and to report to us. " One of them says, the miners and black- smiths of Sweden are well fed, and lodged comfortably ; and he gives us such a picture, uniting vigor, activity, and contentment, as makes it pleasant to travel among their vil- lages. When night comes on, the sensations are different, and almost terrific. The din of so many hammers at work all around, and the streams of light, and flame, and black smoke, issuing from so many forges, powerfully impress the mind ; even the 126 MINE AT DANNEMORA. clouds seem to be on fire, from the red ra- diance. "The most important of the iron mines is at Darmemora,* which was discovered in 1488. The opening of the mine is of great extent, in which, here and there, are twelve pits; and down these the mining operations are carried on. These pits are deep excava- tions, like gravel pits, forming so many gulfs. The descent into them is by means of baskets, or buckets, each attached to a rope, which passes over a pulley; much as if there were a projection from the top of Salisbury steeple, from which, in a basket, one could be let down to the ground. "One traveller, speaking of this descent, says v 'The inspector of the mines accompa- nied me: I was accommodated with a chair; * Dannemora is distant from Stockholm sixty miles, N. N. W. DESCENT INTO THE IRON MINES OF DANNEMORA. 128 MODE OF DESCENT. but he seated himself on the edge of the bucket, extending his legs, in order to maintain our equilibrium. He had a stick in his hand, with which he occasionally pushed off from the edges of the rock, when we were in danger of striking against them. We were above five minutes making this perilous jour- ney. The depth thus descended was five hundred, feet. While I was thus descending, and hung in mid air, another bucket was ascending. I was so giddy, that I did not dare to look down; but as it passed us, I observed three girls in it, or rather on it, as they were each standing on the edge of the bucket, with great unconcern, and knitting all the while, quite at their ease. So much does custom take away the sense of danger. When I rose again, I closed my eyes, till I arrived safe at the surface. 5 DIMENSIONS OF THE PITS. 129 "The motion of these buckets, up and down, is regulated by wheel-work, moved by horses. "The water is drawn out of the mine by pumps, kept in motion by a wheel of great size, said to be above sixty feet in diameter. It is then conveyed away by an aqueduct, a mile and a half long. "The length of these pits, adding them together, is about eight hundred feet ; the breadth varies from three to twelve ; the depth has been ascertained in several parts to be five hundred feet ; but that does not reach the bottom in some places. "This mine furnishes iron in high repute, as being the finest in the world. It is chiefly brought over to England, to supply the man- ufactories of steel and fine goods. "The ore is dug in summer, and laid in heaps ; in winter, it is removed on sledges 9 130 SMELTING AND FORGING. to the several forges. The richest ore yields seventy per cent, of iron ; the poorer sort not half so much. "One of the principal forges is at Loefsta. Here the numerous buildings, and the neat brick cottages for the workmen, make a pleas- ing appearance. "Much as in other places, is the operation of smelting performed. The ore is roasted, then reduced to powder by the mills; it is then melted, and, running into sand moulds, is cast into huge lumps, each weighing above a hundred weight. It is then heated and ham- mered repeatedly, till it is shaped into bars, from twelve to eighteen feet long, and from one to eight inches broad. In this state it comes to us. "One remarkable particular, recorded by another observer, is the manner of obtaining MODE OF GETTING THE ORE. 131 the ore out of the rock ; it is not dug out, as is commonly the case, but torn out by gun- powder. This operation takes place every day, at twelve o'clock, and is a most tremen- dous business. The explosion reverberates among the hollow windings of the mine, like subterraneous thunders. The stones are thrown up, as by a volcano, to a great height in the air; and the concussion shakes the earth all around. " This traveller descended also into the mine, by the same sort of dangerous convey- ance, as the one to whom I have just alluded ; and owns, that he shuddered, and half re- pented his curiosity ; for, in him, it was nothing better. He was nine minutes in a state of suspension, before he reached the bottom. The view of the mine, he describes as awfully grand. Daylight was very faint at these 132 DANGEROUS EMPLOYMENT. depths ; into many parts it could not pene- trate, and they were obliged to use flambeaux. Frames of wood were stretched from side to side of the rock, in some places ; on these, men were sitting astride, at great heights, boring holes for the next blasting. Should they lose their balance, they must fall and be dashed to pieces. " Though the weather was warm at the surface of the earth, yet amid these dark brown caves it was cold. In one of these caverns considerably under the rock, was a charcoal fire, around which were eight mise- rable creatures, eating their meal and warm- ing themselves. The warmth was a great refreshment, for the way was strewed with ice, almost every where in the mines. " Some, who have been disinclined to the airy voyage in the bucket, have descended, BORING THE ROCK FOR BLASTING. 134 USES OF IRON. in another part by ladders. These are crazy things, and would be esteemed very dan- gerous, except as compared with the rope. They are also placed almost perpendicularly, from one projection of the rock to another. There is no small peril in this mode, as might be supposed, if the descent were from the top of St. Paul's ; which is about three-fourths of the same depth. "How necessary is iron to all our manu- factures, and to the cultivation of our fields and gardens ! It is drawn out into vecy fine wire, and moulded into a variety of vessels for domestic use. To convert it into steel, of which our best cutlery is made, nothing more is necessary than to heat good pure iron in a proper furnace, with charcoal, or with any substance capable of furnishing a sufficient quantity of carbon, which is absorbed by the FORMATION OF STEEL. 135 iron in the process. Of this steel are made articles which admit of the most beautiful polish. Iron is more affected by the magnet than any other mineral; and thus it becomes a sure guide to tbe mariner over the trackless waters." COAL. NEWCASTLE.* "CERTAINLY, now we are at Newcastle/' said the father, " we must see how they make coals." " Make coals!" said James. "Nay, father, they do not make coals, they dig them out of the earth, out of deep pits." " I suppose we shall see," was the answer. Accordingly they made the intended visit. * Newcastle, which is situated in the greatest coal district in the world, is a seaport of England, capital of Northumberland, on the north branch of the Tyne, ten miles from its mouth ; one hundred miles south of Edinburgh, and two hundred and seventy north of London. BORING FOR COAL. 137 It happened, luckily, that a friend conducted them to a spot, where they were that morning going to bore for coal, in order to discover if a new mine might be formed. The boring rods are iron bars, each about an inch and a half square, and from three to four feet long; the end is formed into a screw, so that the bars can be joined together, to any length that may be needed. At the end of the first, or lower bar, is a chisel, half a yard long, and about two and a half inches wide ; and at the end of the upper bar is an eye, or loop, of iron, very strong, through which a long piece of timber is put, by which to turn the borer round. James watched the operation, and saw that the men lifted up the borer a little way in the hole it had made, and then let it fall again, taking care to turn it a little round as it fell. M 138 BORING FOR COAL. It is a tedious business, especially when the stratum through which they are boring is very hard, as a rock, for instance. The chisel soon becomes blunted, and must be drawn out, to be replaced by another. Indeed, they fre- quently draw up the borer, and put down a wimble, or sort of scoop, with which they bring up the dust which the chisel has made; and from this dust they can tell what sort of sub- stances they are boring through. When they find coal, their first concern is to clear the water off; for all the joints and separations of the stratum of coal, in general, flow with water copiously. If the coal be so situated, as to height in the hill, that a drain, or level, can be led to it, this is the best way ; unless the distance, or the hardness of the soil, should make it too expensive. In that case, a steam-engine is built, to pump the water out. DRAINING A COAL MINE. 139 When this is resolved on, a pit, or well, about six or eight feet in diameter, is sunk, below the deepest part of the stratum of coal : the water will naturally flow into this, i and clear the mine, if pumped out as fast as it flows in. When the engine pit is prepared, so that the water can be drawn off, they drive the mine, as it is called, so as to come at the coal. We may here give the substance of James's letter to his mother, sent off by post the next day. "DEAR MOTHER, "Our journey into the pit, (we being re- solved to see it,) was, at least to us, rather adventurous. It will do better to read, than to repeat ; as, by the fireside, you will not be in danger, as we were. 140 A PERILOUS JOURNEY. " When we came to the opening of the pit, the first object which caught our attention was the thump, thump, of an enormous steam- engine, which was employed to pump up the water out of the mine. " Near this was a circular hole, down which we were to go ; so filled with smoke, that we could discern nothing else; it seemed like a descent into a vast chimney ; and that, too, while they were busy cooking below. " We were first desired to dress ourselves : indeed, this seemed needful, unless we would utterly spoil our clothes ; as to our faces, we knew, by experience, they could be washed. We put on, therefore, miners' jackets and trow- sers, with caps over our heads ; and, thus ac- coutred, we prepared for our suffocating jour- ney. But how were we to descend? There were no stairs ; but we found prepared, a log DESCENT INTO A COAL MINE. 141 of wood, about three inches thick, and half a yard long ; fastened by a rope at each end, so as to swing horizontally. This sling, or horse, as it is called, was slung by a hook to an iron chain. Each of us, therefore, had to put one leg through this loop, across the wooden bar, and lay hold tight of the chain, by which all was suspended; both of us went together. We were then pushed from the firm ground, and began swinging; and found ourselves gently sinking, by the turning of the ma- chinery, which went by horses. In about five long minutes, for so they seemed to us, we felt the ground again ; and got out, or off of our what shall we call it a carriage? "Feeling our feet again, we began to pe- rambulate ; which we could do as easily as if in our drawing-room. Not that our dresses, 142 INTERIOR OF A COAL MINE. or our black faces, would have been at all suitable for that. We seemed to be entering a vast suite of black chambers, supported and divided by regular pillars of immense size. The roof seemed only about seven feet high, and the chambers about twelve feet wide ; but how far the stratum of coal reaches, they cannot tell, perhaps half under the county; at least, so they hope, and so do we hope too ; for I don't know what London would do for firing, if these coal-pits were to fail. "Now for our ascent: it was by the same means as our descending. We were, how- ever, surprised, when about half way up, to hear a voice say, 'How do you do, gentlemen?' We were so smothered in the smoke, that we could see nobody; but we found it was a common joke, for some of the men to begin PROCESS OF WORKING. 143 descending, and thus meet and surprise the half stupified travellers, in midway of their swinging." In working the mine, a common practice is, to take away the stratum of coal only partially, leaving huge pillars of it to support the roof. When they have thus proceeded some way, the miners come back and work out those pillars ; which occasions the earth above to fall in, and fill up the cavity. These pillars are not left at random, but at regular intervals, and are of regular shapes; from twelve to eighteen feet thick. When they have wrought out all the pillars that can be safely removed, there will be left an eighth or more, of the whole substance of the coal, which they dare not touch. In one place, they saw horses employed in 144 FEMALE COAL BEARERS. drawing sledges, loaded with great baskets filled with coal; five or six, and sometimes eight hundred weight, are drawn out at a time, by one horse, if the slope be not too steep. A mine is formed on purpose, with a gentle slope for them, where it can con- veniently be done. But the surprise of the party was not small, when, coming to a place where no such slope could be made, they found the poor horses let down to their work, tied up in a net. Where the mine is not large enough for horses to work, the coal is removed by men, who drag about half the load of a horse, on a low carriage of four wheels. In some places, neither of these modes is pos- sible ; so the coals are brought out by women, called bearers, who carry them in baskets, on their, heads ; the load is a hundred weight, and often more. And this is done in places where WOMEN BEARING COAL. 10 N 146 NEWCASTLE COAL MINES. the ascent is so steep, that the carriage drawn either by horses or men, could not be used The coal is thus brought from the place where it is dug out, to the bottom of the shaft, which opens to the surface of the earth ; this is some- times a very considerable distance. At the shaft, the coals are put into baskets, fastened to a rope, and drawn up by a sort of windlass, called a gin, set in motion by horses, or by a water-wheel, or by a steam-engine ; as may be most convenient at each place. The depth of some of the mines, below the surface, is often seven or eight hundred feet. When the coals have fairly arrived on the surface of the earth, they are carried a small distance from the mouth of the pit ; and sorted into three heaps, according to their sizes. There are between twenty and thirty coal mines, in the neighborhood of Newcastle. WAGON-WAYS AND RAIL-ROADS. 147 Some are within five miles of the river/and some almost twenty miles distant. To cart so heavy a substance all this distance, would cost so much, that coals in London would amount to double their present price. But knowledge is fruitful in expedients. Wagon- ways, or rail-roads, of iron, are constructed, down w r hich the wagons roll with great ease ; so that one horse will draw as much as ten on a common road. A rail-road consists of two shallow grooves of iron, well fastened on stone work in the ground, upon which the wheels of the carriage run ; or, sometimes, the rail- way consists of an iron ridge, fastened as before; and then the iron wheels of the car- riage have each a shallow groove to work upon it. The wagons are of a funnel shape; and when one arrives at the wharf, a door in the bottom is opened, which lets the coals 148 KEELS AND KEELMEN. through, into the keel, or barge, which is placed properly underneath. The keel is a clumsy oval-shaped barge, in which the coals are rowed down the river, to the ships, which wait to receive them. The keelmen are a numerous body, rough and hardy ; not fewer than six thousand in number. But it is calculated that almost seventy thousand persons are employed by these mines, in various ways ; and the ca- pital by which the works are carried on, amounts to more than three millions ster- ling. In one part of the mine, an accident had recently happened, called a crash. The pil- lars left to support the roof, being too slender, had failed ; or else the floor of the mine was too soft, and had suffered the pillars to sink in; so that the roof fell in, with the whole FOUL AIR IN MINES. 149 mass of earth above it. This sort of accident seldom happens without giving notice, by pre- vious cracks, and the falling of detached pieces from the roof. In this case, the miners some- times build up stone piers, to support the roof, if a fall in that spot would greatly hin- der the work ; otherwise they clear away more of the coal pillars, and let it sink in gently. Many dreadful accidents arise from foul air, of which there are two sorts : one, the black damp, is of a suffocating nature ; the other is inflammable, and, taking fire, explodes with great violence, or, perhaps, sets on fire the w r hole body of coal, so as to destroy the mine. The workpeople take great care, therefore, to bring a current of fresh air into the mine, which carries off the foul gas, and 150 THE SAFETY LAMP. prevents its accumulating to any dangerous quantity. A few years ago, a dreadful explosion oc- curred at the Felling colliery, near Newcastle ; and as these accidents are too sudden to allow of escape, more than one hundred persons, who were at work in the mine, perished in an instant; and nearly five hundred widows and children were plunged into distress and destitution. Philosophy has, in modern times, endea- vored, with some success, to guard against this calamity, so terrible and so irresistible. Sir H. Davy has invented what is called a safety lamp, for the use of men working in the mines. It consists of a common lamp, covered with a skreen of very fine wires, woven very closely together. The light THE SAFETY LAMP. 151 passes between the bars, in a sufficient degree to assist the workmen ; but the foul air is so dense, and, one might almost say, so ropy, that it cannot pass between the wires to get at the flame; and nothing short of actual contact with the blaze will set it on fire. COAL. SUNDRIES. ALTHOUGH Newcastle has long been the grand source of supply of coals for London, as well as for the eastern and a considerable portion of the south coasts of the kingdom, yet there are many other mines of this precious substance. It has been calculated, that as a mere com- modity for sale, more value has been raised from the coal mines, than from the silver mines of Potosi, or the gold mines of Mexico. This value becomes enhanced to the nation, in an almost incalculable degree, by the use to which ANNUAL SUPPLY OF COAL. 153 coal is put in manufactories. A hundred pounds worth of coal employed in steam- engines and iron forges, soon produces its thousands in some useful or ornamental article. The various fabrics thus brought to perfection, from the huge anchor of a man of war, to the delicate bobbinet-lace of a lady's fashionab 1 - dress, with numerous et ceteras, are beyond calculation. Were the coal mines to cease, nine-tenths of the activities of the British empire must cease also. " One would think," said James, " that, so much as they dig out every year, they must soon come to the end of the mine ; and then, what should we do for coal?" " That may become a serious question, some day," said Mr. Thompson. "Especially con- sidering that they have been digging here four hundred years ; and that they now excavate 154 BORROWSTOWNESS COAL MINE. to the amount of one million eight hundred thousand chaldrons every year, to supply London only ; add to this what the eastern and southern coasts of the kingdom consume, and what is exported to foreign nations ; and we shall make a total amount of two and a half millions of chaldrons, dug out every year." " I hope it will last my time !" said James. " Posterity may thank you for such a selfish wish ; but such privation need not be feared yet. Newcastle and its neighborhood can supply us for four hundred years more; and there are many mines in other parts of the kingdom, some of which have never been worked, but which would become of value, if our present means of supply should fail. " One of the most remarkable mines of coal was found in the parish of Borrowstowness, in Scotland. This mine penetrated to a great MINES FROM UNDER THE SEA. 155 extent under the sea. About the entrance, which was situated half a mile from the beach, an embankment was made, to keep off the waters; and ships could lie close up to take in the coal. Several springs of fresh water oozed into the works ; but the water was drawn off by an engine, moved by the tide. For many years this was a profitable concern, and brought great wealth to the Earl of Kin- cardine, to whom it belonged. The end of it was, however, very calamitous. An unusually high tide overtopped the mounds around the entrance ; the sea rushed in, filled the mine, and drowned all who happened to be at work in it at that moment. It has not been wrought since. " At Whitehaven, in Cumberland, is a mine very similar ; as it runs under the sea to a great distance. The works are sunk almost 156 CANNEL COAL. eight hundred feet deep; and vessels ride at anchor, over the heads of the miners. " A peculiar sort of coal, called Cannel Coal is found in Staffordshire, Cumberland, and Lancashire. It is so hard that it will not only admit of being turned in a lathe, to form boxes, and ornamental articles, as inkstands, salt- cellars, candlesticks, &c., but it will bear a polish, and will not soil the most delicate linen. It is, however, chiefly used for fuel ; and it gives a remarkably clear flame, like a candle ; whence its name, possibly : but it must be sprinkled with water before it is laid on the fire, otherwise, as soon as it gets warm, it will crack and fly into the room, in a multitude of small pieces. It is said, that the chequered pavement of Litchfield cathedral is laid with cannel coal for the black squares, and alabaster for the white. A CURIOUS DISCOVERY. 157 "Bovey Heath, in Devonshire, has a remark- able species, which bears its name, Bovey Coal: it has the appearance of having been originally wood. A similar kind is also found in Scotland and in Iceland. " A curious discovery was made, some years since, at Bally castle, in Ireland, of an ancient coal mine. The colliers were carrying a new adit, or roadway ; and meeting with a stratum of rock, they bored through it. They then perceived they were entering into a vast cavern. As the opening made was as yet but small, they caused a couple of boys to creep through, with lights, to discover to what and where they were come. These soon lost themselves in the windings of the cavern. The workmen then enlarged the hole, and, going after them, perceived they had entered a mine, which led them a long way, and 158 COLLIERIES AT DYSART. i branched off into many chambers, which had been worked ages before, as no traditional remembrance or history of any coal mine there, was in existence. Pillars were left to support the roof, much after the modern custom. Some remains of tools and baskets were found; but so decayed, that they crumb- led to dust on being touched. That it was long, long ago, since these chambers had been worked, was evident, as stalactite pillars were formed by the dripping of water through the rock above ; some of them reaching to the floor. Such pillars of such a size, could only be formed during the lapse of many ages. " In Scotland, there are many coal works. " Near Dysart,* is a collection of collieries, remarkable for having many of the beds of * A seaport on the Frith of Forth, twelve miles north of Edinburgh. COLLIERIES AT DYSART. 159 coal on fire, which have been burning for two centuries. At present the heat only warms the earth, so as to prevent snow from lying long on the surface ; but, in times past, there was smoke by day, and flame by night, to a very awful degree. " A traveller who visited the Dysart mine, writes thus: 'I have made a journey lately, where there were no trees, no fields: there was a river, indeed, beside us, but no fish ever swam in it ; and in the air far around no bird has ever been known to fly ! I have been in the coal mines at Dysart. I repaired to the inspector's house, and was dressed. Conceive my slender body wrapped in a sailor's jacket and trowsers, which had been made for a stout man. I was crowned with an immense old hat, which had an irresistible tendency to rest upon my shoulders. After half an hour's 160 COLLIERIES AT DYSART. walk in this fantastic attire, during which time I afforded some merriment to the natives, we reached the place of descent. It is a perpen- dicular shaft, with a wooden partition in the middle, reaching to the bottom. On one side of this partition are placed short w r ooden ladders, in a zigzag direction, from top to bottom of the pit. "'Having each lighted his candle, we began to descend, and were right glad, after some fatigue, to find we had reached the bottom; though we were still half a mile from the shaft where the coals are taken up. My friend led the way with a lantern ; and we soon began to perceive that we had entered a spacious gallery, the roof of which was about twelve feet high. By the glimmer of our candles on the right hand, the wall seemed to be solid; but on the left now and then appeared a MINES AT DYSART. 161 spacious gloomy cavern, which seemed to turn at right angles to the route we were pursuing ; but how far we could not tell, it was all impenetrable darkness. We were then walk- ing in what the miners call the level. On our side, a river flowed, fed by streams from various caverns, or sometimes by a waterfall, where the roof had given way. Hitherto the murmur of the stream had alone broken the dreary stillness of these caverns, and the feeble rays of our candles only made visible the dark- ness which they could not dissipate. But now other sounds and lights began to burst upon us : a fire was seen blazing at a distance, and a number of motley faces danced and gleamed before us, like the figures of a magic lantern. The clanking of chains and the trampling of horses, were now distinctly heard; and a hollow sound as of distant thunder grumbled 11 O 162 INTERIOR OF THE through the subterranean vaults, as the loaded baskets were dragged along. "'We had now, in fact, arrived at the pit, where the coals are raised by a steam- engine. We had not yet travelled over half our ground, but the remainder of the journey was more expeditious. A train of empty baskets was ready to move, in which we made ourselves comfortable seats with straw. Our horse was harnessed, our light adjusted, and in a few minutes we started at the full trot, to explore the yet unseen recesses of this seemingly endless labyrinth. After tra- velling another mile, we arrived at the place where the men were at work. Here the air was very close, from the smoke of their lamps ; and we were glad to make our way back on loaded baskets, though contrary to the laws of these realms. We took no candles in TREASURES OF THE EARTH. 163 returning, as a lamp is attached to each train of baskets. By accident this only remaining light went out about the middle of our journey, and we were left in darkness, of which those above ground can form no conception. Our horse continued to canter along, as if nothing had happened, at a rate which made it a little difficult for me to keep my seat. In some time, a twinkling lamp appeared at a distance, on passing which, things went on as before. The baskets we travelled in are set on wheels, which move in a railway. The horses are in excellent condition, and have good stables in the mine. They never see the light of day from the time they are first lowered down. Our return need not be described any far- ther/" GOLD. GOLD is one of the purest metals; and, on that account, not liable to perish by rust, or by fire. It is malleable, ductile, resplen- dent, and the most weighty of them all: half as heavy again as lead, and more than nine- teen times the weight of water, bulk for bulk. Gold is found in primitive mountains, usu- ally in slender veins, often penetrating the hard rock itself. But it is more commonly ob- tained in small grains, from alluvial soil, that is, such as forms the beds of rivers, or the sides of channels which have been created by floods, and are frequently covered with water. Many have supposed that these frag- GOLD IN SANDS OP RIVERS. 165 ments are washed down from the adjoining mountains ; and persons have frequently en- deavored to trace them up to their supposed original beds in the mountains, where they hoped to find the parent vein, and become rich at once : they have, however, been dis- appointed. Nay, where the sands of the rivers afford golden grains, these particles have become more scarce as the searchers approached nearer to the rocks from which the streams have issued. The gold, indeed, appears only here and there : it is not the whole channel that affords the particles of metal, but only some particular districts, through which the stream passes. The term "Mine," which seems to imply some hollow, artificially excavated beneath the mountain, must, in this instance, be transfer- red to places where the miners merely dig 166 GOLD IN SANDS OF RIVERS. up the surface of -the soil, and wash it, in order to separate the precious grains from the earth. GOLD. SUNDRIES. THE most ancient gold mines, of which we have any account, were in Spain, in the northern provinces. Thither the Phoenicians used to repair for the precious metal. The Romans also, when they conquered Spain, employed the native Spaniards to dig their own mines for them; much as, in later times, the Spaniards have forced the Indians of South America to dig for their profit. The mines in Spain consisted of veins of gold, running in the rocks ; but they have been long neglected ; indeed, ever since the discovery of America has enabled the Spaniards to obtain gold in a 168 GOLD MINES IN HUNGARY. more easy and plentiful manner. In the time of Nero, fifty pounds of gold were obtained daily from the mines of Dalmatia. It was found on the surface of the ground. The island of Thasos, in the JEgean Sea, also yielded a considerable quantity. France has never been famous for gold; yet some has been found in a few of her rivers. At Gar- dette, in the hard rock, were some veins of native gold ; but not in sufficient quantity to be worth the working. A little is found in Mount Rosa, in Piedmont, just enough to pay for obtaining it. We find yet more among the craggy mountains in the Tyrol. Hungary has been much celebrated for its mines, and not without reason. The modes of operating, and the machinery, are not equal to those in use in England ; but they are very SCOTTISH GOLD MINES. 169 carefully wrought. It is supposed that nearly six hundred thousand pounds, in gold, are raised every year at Schemnitz and Cremnitz. One third as much of silver, besides lead, is drawn from thence. These are the only gold mines in Europe, of any importance. Sweden has some gold mines at Edelfors; where native gold, in veins, traverses a rocky mountain. Russia has a mine at Voetsk, north of the lake Onega ; but not in sufficient quantities to be worth the working. In Scotland, gold was found, ages ago And in the reign of Elizabeth, considerable quantities were collected between Leadhills and Elvanfoot. The traces of the works then carried on yet remain. The gold was found immediately under the vegetable soil. Hither a small stream of water was conducted, in P 170 WICKLOW GOLD MINES. order to wash away the light earth into pools, or basins, dug on purpose; in this state of loose mud, the heavier particles sank in the pit, while the mere earth was carried off. All those heavier matters which sank, were after- wards well washed, and examined for the grains of gold. Gold is still found in Scot- land; but the increased expense of seeking it, renders the search unprofitable. Some of those who work in the adjacent lead mines, amuse themselves in their spare time, and now and then pick up a little. Much was said, a few years ago, concerning the mountains of Wicldow, in Ireland. There some large lumps of gold were found, in a sandy soil. Several were of an ounce weight each, and one lump weighed twenty-two ounces. This is said to be the largest mass of native gold ever found, any where. ASIATIC GOLD MINES. 171 We expect to find gold in Asia; especially as all our histories of the earliest ages, even long before Nebuchadnezzar's golden image, ninety cubits in height, was erected, speak of gold being in great plenty. Solomon made it to abound so, that silver was little thought of. Nay, as far back as the time of Moses, and the erection of the tabernacle in the wil- derness, we find it in plenty. The whole continent of Asia seems to furnish it; from Siberia to India, and from the western pro- vinces to Japan. The mines of Beresof, in Siberia, are still wrought; those of Tcherepa Nafskoy are very rich in gold. In the south- ern parts, as in India, many rivers furnish the precious grains. A river in Lydia, called Pactolus, which empties itself into the Archi- pelago, was famous in ancient story for its golden sands. The river runs by Sardis, and 172 AFRICAN GOLD MINES. is said to have been the chief source of the long famous riches of Croesus. In the east, the islands of Japan, Vonnosa, Ceylon, and most of the islands in the Eastern Sea, much gold is found at the present day. Africa has always been rich in gold. The ancients had much from it. That Ophir, from which Solomon received his supplies, is thought, with great probability, to have been on the eastern coast, somewhere about where Sofala now stands. Gold is still an article of com- merce with all the Cafilas which traverse its dreary deserts. This is evidently the produce of the rivers ; as it comes only in the shape of dust, or very small grains. It is brought for sale in quills of the ostrich and the vulture. The centre of Africa has always been esteemed rich in gold. Herodotus tells us, that the King of Ethiopia brought to Cambyses all his pri- AFRICAN GOLD MINES. 173 soners bound with chains of gold. That part of Africa which lies more to the southward, which we trade with on the western side, by the ports of Guinea, Upper and Lower, pro- duces much gold from its rivers, such as the Senegal, the Gambia, and the Niger. GOLD. MEXICO. AT the present day we turn our eyes to the New World, in search of golden treasures. Ever since the discovery of America, gold has been the grand object of research with the European settlers, and their descendants, in the middle districts. That those regions abounded in this splendid metal, we have undeniable testimony to prove ; the quantity discovered in use there, and the quantities gained from thence every year, establish this point beyond contradiction. It is said, that, in gold and silver, America sends annually to RICHES OF ANCIENT MEXICO. 175 Europe, twenty -four millions pounds sterling in value. When Cortez landed in Mexico, the most costly presents were made him by the natives, in the hope of civilly prevailing with him to depart ; but the value of these presents deter- mined him to stay in a country where such magnificent commodities could be procured. Among them, were two large plates ; one of massive gold, representing the sun, and one of solid silver, for the moon ; besides boxes filled with grains of virgin gold, just as they were obtained from the rivers. Even the governors of the provinces made him presents of immense value, in gold; which, though known to be in high esteem, was in that country plentiful. The description of Mexico itself, its palaces, and its temples, evinces the great abundance 176 UNCERTAINTY OF GOLD MINES. of gold, in the massy ornaments of that metal, which glittered on every side. When Cortez retreated from Mexico, he left behind him, above what the soldiers could carry away, gold, &c. to the value of two hundred thousand pounds ; and in stripping the slain after the battle of Otumba, his soldiers gained an almost equal value. As gold was their principal object, they, soon after gaining the country, searched for the mines themselves, and forcibly obliged the natives to dig in them. It is calculated that forty thousand of them are still kept to this labor, in New Spain only. The principal mines are situated inland, far from the sea ; in the provinces of Zacatecas, New Biscay, and Mexico Proper. But the veins of gold are small, and the produce uncertain. It has been observed, that gold VARIOUS STATES OF GOLD ORE. 177 mines have generally ruined those who en- gaged with them ; although the purifying of the ore is not so expensive as that of other metals. This happens, because the veins are very apt to fail. For a while, the vein will be full and rich, and then it is lost on a sudden : when, indeed, a vein can be traced to its end, the miners frequently find what is called the purse of the mine, or such a considerable quantity as at once makes the fortune of the adventurer. These mines are not wrought at the public expense; but any man, who suspects gold in any place, may obtain a grant of the land ; only stipulating to begin working within a certain time. The gold here, as in other parts of the world, is found in two different states ; either within the rock in veins ; or scattered in morsels, in 12 178 OPERATIONS TO OBTAIN GOLD. the sands of rivers. When obtained from the rocks, which must be burst asunder to get at it, it is sometimes found in lumps, or masses, of pure metal, called native gold; but, more frequently, it exists in a mineralized state, mingled with other substances, as earth, stone, sulphur, &LC. In this state it would not be recognised by an ignorant person ; for it is red, white, black, as may happen, and shews none of its brilliancy or metallic cha- racter. When gold is found in this state of mixture, the ore is broken in pieces, in a mill, consisting of an upright, circular stone, which turns on its axis, while it traverses a circular trough ; such as is employed in grinding bark, in England. When thus broken, some of the refuse is easily' separated from it. To the remaining mass, a considerable quantity of quicksilver is added; BREAKING GOLD ORE IN MEXICO. 180 OPERATIONS TO OBTAIN GOLD. which, having a strong attraction for gold, fastens upon every particle of it, and draws it away from whatever it had been attached to. When the gold is thus amalgamated with the quicksilver, a full stream of water is let into the vessel, which carries with it the lighter matters, earth, &,c., and leaves at the bottom the heavy metal : the amalgam, thus cleansed, is squeezed in a cloth ; much of the quicksilver is thus forced out, and the remainder is driven off by fire, which leaves the gold pure. When the miners suspect gold to be in the bed of a river, they turn the stream away from those spots in which they conceive it may lie. Then they loosen the bottom of the river, by digging ; and in this loosened state the soil is easily washed off by the current, which is let in suddenly for the purpose ; and a stiff earth remains in which the gold is concealed. The GOLD WASHING IN MEXICO. 182 OPERATIONS TO OBTAIN GOLD. waters are again turned off, and the workmen dig up this earth, which they carry away to the lavaderos, or washing places. Here it is kept continually stirred with iron hooks and rakes, while water, rushing in, carries away the earthy matter ; and the gold, from its weight, falls to the bottom. Still it is mingled with a black heavy sand, which hides the gold, unless there be a few lumps larger than the general size ; and to get rid of this sand, it is put in succes- sive portions into a shallow dish, deepest in the middle, and filled up with water. With their spread fingers, they whirl the whole round and round ; so that the water and sand pass over the edges of the dish, and the pure grains of gold remain in the central hollow. This gold is obtained without the aid of quick- silver or fire. GOLD. PERU. IF we pass to South America, we may con- template the conquests of Pizarro; and we shall find a great display of its golden trea- sures. When he first seized the too credulous Atahualpa, after murdering thousands of the unresisting Peruvians, the spoil taken from the slain amounted to such a mass of wealth, as made the Spaniards almost frantic with joy. The captive monarch, finding that gold was their grand object, hoped to gain his liberty by offering an immense ransom. The room in which he was confined measured twenty- 184 RICHES OP ANCIENT PERU. two feet in length, and sixteen in breadth; and Atahualpa offered to fill it with golden vessels as high as a man could reach. His offer being accepted, he sent messages through all his dominions ; and from the palaces of his nobles, and the temples of their gods, came the golden vessels, in obedience to his orders. After one fifth had been deducted for the use of the King of Spain, the value which Pizarro immediately shared among his partj^ amounted in value to three hundred and twenty-six thou- sand six hundred pounds sterling. But though this perfidious Spaniard had obtained the sti- pulated ransom, he refused to liberate the cap- tive monarch. * When he took possession of Cuzco, the booty he found there greatly exceeded in value what be had forced from Atahualpa. MINES NEAR LIMA. 185 Plates of gold and silver covered the walls of the temples, and the shrines of the ido- latrous worship. The gold mines of Peru are situated chiefly in the northern provinces, almost in the neigh- borhood of Lima. These mines tempted many to devote their whole strength to them. But this mode of advancing their wealth came into disrepute, from the circumstance, that although a few large fortunes had been realized, yet the great proportion of persons engaging in them had spent their property, and were reduced to great indigence. Indeed, to prevent their be- ing abandoned, the government was obliged to remit the fifth which had been previously claimed; and be content with a twentieth of the metal extracted. In the more northern provinces of South America, much gold is found. In the province Q 186 GOLD FROM ALLUVIAL SOILS. of New Granada, near Santa-Fe-de-Bogota, it is obtained from alluvial soils, and cleansed by simple washing. It is found in considerable plenty near Pampeluna, where a single laborer has sometimes found as much as was worth two hundred pounds, in a day. One lump of virgin gold was brought from Santa Fe, worth almost right hundred pounds sterling. GOLD. BRAZIL. BUT the greatest quantity of gold brought into the market, in the present day, comes from Brazil. The discovery was made by a party of soldiers, who were sent into the inland provinces to quell an insurrection, and found among the natives some fish-hooks made of gold; on inquiry, they were informed that the gold was brought down from the mountains by the floods, when the torrents came rushing into the valleys. This was enough to instigate a diligent search. It is true, only a few veins of gold were discovered ; but the quantities of grains found after the floods, exceeded belief. 188 GOLD BROUGHT PROM BRAZIL. This searching for gold is now the employment of negroes, who have this privilege, that if any one brings the quantity required of him, his master cannot demand of him any more. Should he find more, therefore, it becomes his own property ; and, if he can save enough of it, he may purchase his freedom. The registers of the fleets shew, that in about sixty years after the discovery of the gold mines of Brazil, the value of bullion brought to Europe, amounted to upwards of one hundred millions sterling. It is seventy years since that calculation was made; how much more must have been brought in that time ! * It is affirmed, that a single grain of gold can be beaten out, or spread into a leaf of fifty square inches ; and that this leaf may be rea- dily divided into five hundred thousand parts, DUCTILITY OP GOLD. 189 visible to the naked eye. It is asserted, also, that one grain of this metal, as thin as that with which artists gild what is called gold lace, would cover a surface of nearly sixty square inches. And again, that a grain of gold may be stretched in such a manner as to cover more than sixty-three yards of silver wire. Indeed, the ductility of this metal is almost incvedible. HUALPA DISCOVERING THE SILVER MINE OF POTOSI. SILVER. POTOSI. "Now we are in South America, we may as well notice the silver mines of that country. We can leap over the Andes easily, as we sit here, and come at once to Potosi." JAMES. "I think, I remember something about Potosi." " Well, let us hear all you can recollect." "Why, I think, an Indian, what was his name? O Hualpa, was scampering up the side of a mountain, after some wild animal or other : finding it had jumped up a steep place quicker than he could, and determining to follow it, he laid hold of a branch oi a .shrub, 192 HUALPA THE INDIAN. to assist him in climbing. But instead of assisting him, it broke off in his hand, or rather it was torn up, root and all, out of the earth. He was, however, repaid for his disappoint- ment, by the sight of something bright in the hole which the plant had come from. He soon discovered this to be a lump of silver; and he found several small bits sticking about the roots. These he picked off carefully, that he took up lovingly, and home he went joyfully ! Right glad was he to have found such a treasure." "What, then, did he keep it all to him- self?" "No, father. It would have been better for him, if he had. He returned to his mine, whenever he wanted cash ; and by that means grew so much better in his circumstances, that his neighbors wondered at it. One of POTOSI SILVER MINE. 193 these was his particular friend : so, whether to stop his inquiries, or to give him a share, I do not know ; but he told him of his dis- covery, and shewed him the place ; and they both helped themselves as they happened to want." " Well ; but as there was enough for both, was it not better to let his friend have a share?" "Yes, I suppose so, if he could have been sure of his friend. But some disagreement between, them arose, because Hualpa would not tell how he purified it ; then this un- worthy friend went and told the whole to a Spaniard. The mine was soon taken posses- sion of, and the poor Indians got no more. The mine, indeed, yielded a great deal; but the Spaniards took it all. This was in 1545." 13 K 194 POPULATION OF POTOSI. "And does that same mine continue to yield silver still?" said James. " Its productiveness was soon put to the trial ; for a town was built at the foot of the mountain ; ten thousand Spaniards settled there, to gain the silver; and sixty thousand poor Indians were forced to go thither, to dig out the ore for them. This mine is still worked, as are several others, in the adjacent mountains. The country around is barren, as is usually the case where there are metallic treasures underneath. The inhabitants of Po- tosi are obliged to procure nearly the whole of their provisions from the neighboring pro- vinces. "This mine is in a mountain by itself, like a sugar-loaf in shape. The city of Potosi, although at the foot of the mountain, is not IGNORANCE OF THE MINERS. 195 in a valley, but high up in the Andes, whose white tops, covered with snow, glitter at a few miles' distance. It is now a large city, containing a hundred thousand inhabitants, including slaves. It does not belong to the western or Peruvian coast, but to the eastern side of South America, being in the govern- ment of La Plata. "The mountain itself is about eighteen miles in circumference, at bottom. The miners do not proceed in any regular or scientific manner, but they get as much sil- ver as they can obtain easily; none of them have penetrated above seventy yards into it, though there are more than three hundred pits ; but they content themselves with scoop- ing out the mere surface of the hill. An old conduit, which, a hundred years ago, led into 196 IGNORANCE OF THE MINERS. several mines, is now filled with water, there not being any sufficient machinery to clear it off. The mountain itself seems to be a mass of clayey slate, yellowish and hard. Although it has produced so much since it was opened, yet it yields only about six or eight ounces of silver in five thousand pounds weight of the ore. All the processes for roasting, amalga- mating, or refining the ore, are conducted in a slovenly manner, by persons ignorant of all scientific modes of operation. They mingle quicksilver, to extract the metal, as is done with gold ; but they do not get half the silver out again ; and the waste of quicksilver is enormous. All the tools, too, with which the poor Indians work, are heavy and unsuitable. " Some German miners have been over there lately, who are shewing them how to MINE OF LAYCACOTA. 197 conduct the works in a better manner. If proper improvements be made, the produce may become at least double in its value. " We may mention too the mine of Lay- cacota, which was discovered in 1660, near the town of Puna. Here the virgin silver was in such abundance, that it was cut out with a chisel. The proprietor of the mine, with a liberality rather uncommon, permitted his countrymen, who came from Europe to seek their fortunes, to work in it a certain number of days, and take all away they could thus dig out, without weighing or examination. This generosity brought plenty of visitors, who soon began quarrelling with each other about their shares. Disagreements about such valuable spoils brought on blows ; they armed themselves, in order to repress their neighbors avarice; and, in the end, the good-natured 198 MINES IN PERU. Salcedo, the original proprietor, was himself hanged as the author of those tumults; al- though he had endeavored all he could to prevent them. "Peru is said Jo contain sixty-nine mines of gold, and seven hundred and eighty-four mines of silver ; all of which are wrought more or less." SILVER. MEXICO. THERE are silver mines in Mexico, as well as mines of gold. Indeed, silver, al- though the second in rank, is first in im- portance in a commercial point of view, on account of the much greater quantity obtained from the mines. Silver, as is the case indeed with most other metals, is found in a variety of different ores. It is sometimes pure, or in veins which pene- trate every crevice of the stony rock to which it adheres; but, more frequently, it is mixed with other matters, which must be separated from it ; so that its first appearance varies 200 MINES IN MEXICO. much, as it is ash-colored, reddish, bluish, often black, and sometimes in pointed forms, like crystals. The manner of refining it differs but little from the processes used with gold; except that none is obtained by mere washing, though it is cleared from earthy particles with water. The workmen depend chiefly upon amalgamat- ing it with quicksilver : but in this case there is more difficulty than with the gold; as the silver clings more powerfully to the mineral substances with which it is united, and the process requires more labor and care. The mines of Spanish America are wrought by private adventurers, who are. encouraged to the work by grants of the land to those who suppose they have made a discovery, and are willing to seek wealth in this mode ; the governor of the province only binding them MINES IN MEXICO. 201 to begin in a stipulated time, and insuring one fifth of the produce to the King. There are always persons bold enough for such an under- taking, as it is easy to make the experiment; and, now and then, vast fortunes are realized by such speculations. Indeed, so fascinated are the Spaniards, who go over from Europe, by this silver dream, that they neglect that more certain produce, which the surface of the earth yields to the labors of the agriculturist. SILVER. NORWAY. A SILVER mine of much celebrity is found in Norway, at Kongsberg, in the province of Aggerhuys, not a great way from Christiana, the principal seaport of that country. Kongs- berg, which has the river Lowe running through it, may contain about six thousand inhabitants, of which number the miners make nearly half : the mines are about two miles from the town. There are almost forty mines in work ; and the principal one is called Segen-Gottes. This is nearly seven hundred feet in perpendicular depth below the surface MINES OP KONGSBERG. 203 of the earth. In many parts of the descent, a staircase is cut in the solid rock. The mouths of the mines are made very wide. Working the mine is very laborious, on account of the hardness of the rock ; but the miners are not much troubled with water to flood the works, which is a great advantage. Pounding the ore is one sort of process in use here, as in most places. It is also smelted with lead, to separate it from extra- neous matters. Pure silver is sometimes found in feathery clusters, or foliage ; but chiefly in small grains. Once, indeed, a large mass was found, valued at six hundred pounds, as pure silver. This, as a great curiosity, is preserved in the King of Denmark's cabinet, at Copenhagen. The expenses of working this mine amount to as much as the silver is worth, when 204 "OLD G-OD'S BLESSING." brought to market; so that the government, at whose expense it is conducted, gains little by it. The chief use of it is, to find employ- ment for some thousands of poor people, who otherwise could have no means of mainte- nance; and to bring a quantity of specie into circulation, as that, though very necessary, is a very scarce commodity; commerce being carried on chiefly by paper notes. The mine was discovered in 1623; a town was immediately built, and a colony of German miners was sent thither. There are twelve veins and forty shafts. Some gold has been found here among the silver. One of these mines is called " Old God's Blessing ;" this is still very rich. With some anxiety, the traveller descends above a thou- sand feet deep into the earth. When he arrives there, he finds a space cleared out, "OLD GOD'S BLESSING." 205 of several hundred fathoms in extent. In this gloomy cavern, he sees fires blazing all around him, in thirty or forty different places ; these fires are kept up, in order to soften the rock, and make the work easier to the miners. The swarming of hundreds of miners, black- ened with the smoke, passing about on every side, adds to the awfulness of the scene, and helps to give it so much the more resemblance to what imagination had formed of the infernal regions. This becomes heightened, when a mine is sprung, to blast the rock with gunpow- der; as then several hoarse voices cry out, " Take care of your lives !" SILVER. SWEDEN. IF we pass into Sweden, in search of silver, we must stop at Saalberg, near the town of Sala, in Westermannia. This is the only one rich enough to be worthy of our notice ; and this is so ancient, that no records tell us of its discovery. The depth of the mine is almost a thousand feet ; there are some landing places, so that the miners do not descend the whole depth at once ; which is, to our apprehension, so much the better, because they are let up and down in baskets in two considerable lengths of the descent, though they have ladders in a few places. THE SCORIA REFINED. 207 The inside of this mine is very grand; the roof looks like that of some old Gothic cathe- dral, supported by slender pillars of ore, left in regular order. The brilliant masses, glittering all around, arouse our admiration. The ore seldom yields above four pounds of silver in the hundred weight, and requires much trouble to obtain it. In times past, the scoria was thrown away ; but a German has discovered a method of extracting silver from that which was once thought to be rubbish. How frequently do we see the improvidence of the ignorant, while the man of knowledge is ready to turn almost every thing to account. SILVER. RUSSIA. RUSSIA has some silver mines ; those at Kolyvan are the most important. These are far off, in Siberia, in mountains adjacent to Chinese Tartary. They were discovered by Akinsi Nikitich Demidoff, For some years, he gave out that they were copper mines, and worked them on his own account. Being afraid, however, of being discovered and pu- nished, (because all gold and silver mines belong to the crown,) he himself gave in an account of them to the Empress Elizabeth, who of course seized upon them, as her own property. There is but little wood near PRODUCE OF THE KOLYVAN MINES. 209 the spot ; therefore, smelting works have been erected at Novopaulofsk and Susunsk, in the neighborhood of forests, whither the ore is transmitted, to be smelted and pu- rified. These mines may be called the Potosi of Russia. They produce nearly ten thousand pounds of silver annually. When this silver comes to Petersburgh, it is smelted again, in the imperial laboratory ; and it yields three per cent, of gold. So that in the annual pro- duce of silver, there are twelve or fourteen hundred pounds of pure gold. The mines of Kolyvan employ nearly forty thousand persons, (without reckoning the pea- sants of the adjoining districts, who pay their poll-tax in wood and charcoal,) in bringing these materials to the place, and in trans- 14 s 210 MINES OF NERTCHINSK. porting the ore to the smelting towns. A mint is established at Susunsk, where the coinage of the copper obtained from the same mine is performed. The silver pro- duced here is conveyed to Petersburgh on large sledges, a number of which, under con- voy, reach that capital twice in the year. Still more to the eastward, in the province of Dauria, the south-easternmost part of Sibe- ria, between the rivers Shilka and Argoon, are the mines of Nertchinsk : these were opened in 1704. The annual quantity of silver pro- duced on an average, is about sixteen thousand pounds ; besides gold amounting to five hun- dred pounds, which is obtained from it when refined a second time at Petersburgh. Silver constitutes a large portion of the money of all civilized nations. But, when MINES OF NERTCHINSK. 211 used in coin or plate, it is usually mingled or alloyed with a small quantity of copper. If kept in proper condition, it has a lustre of great beauty. LEAD. DERBYSHIKu;. THE county of Derby abounds in wonders, especially about the Peak. Curiosity, rational curiosity, may have a feast, whatever be the peculiar taste of the party. Pleasure and amusement are all that some pursue ; and if these can be made subservient to the attainment of rational knowledge, it is well. Some of the curiosities are in situations cal- culated to alarm the visitor; we can hardly recommend the young and the feeble to en- counter the hardships and danger necessary to the sight of them. It is well for such, that travellers of more strength of constitution, and MAM TOR. 213 firmness of nerve, have been there before them. Mam Tor, or the Shivering Mountain, af- forded our inquirers much amusement ; as did several others of these wonders of nature. But the present object of our inquiry is, the nature and appearance of mines. Mam Tor is seen at a distance, towering above its neighboring mountains, and rising to the height of thirteen hundred feet above the valley. Now near the bottom of Mam Tor, is a very ancient and a very curious lead mine. It seems to have been wrought at least as far back as the time of the Saxons, for it bears the name of Odin: yet it affords to the present day employment to a tolerable number of people. There are two levels, as they are called: 214 SINGULAR PROPERTY OP THE ORE. the upper one is a passage for carts, by which the ore is brought out of the mine ; the lower level is a water drain, to keep the mine in a proper state for working. These levels pene- trate above a mile into the interior of the mountain, running horizontally. The ore is of the sort called galena, having a fine polish, almost equal to a mirror; it is here known by the name of slickenside. One of its great peculiarities is its aptitude to ex- plode : when a sharp iron wedge is driven into it, it begins to crackle ; and in a few minutes it will burst and fly to pieces, as if it had been blasted with gunpowder. The miners must hastily get out of its reach, or they may suffer for their temerity. In the mines at Eyam, in this neighborhood, a violent explosion of this nature took place in the year 1738. Then the surprising quantity SINGULAR PROPERTY OF THE ORE. 215 of seven or eight hundred weight of mineral matter was thrown out at one explosion. The concussion was so great, that the upper surface of the ground was seen to shake, as if an earthquake had happened. LEAD. STAFFORDSHIRE. ONE lead mine is called the Staffordshire Speedwell, the entering into which is amusing. " We put ourselves under the guidance of the manager, who conducted us, through an opening, down above one hundred steps, formed almost perpendicularly. At the bot- tom of this descent was a river, and a boat ready for us, with a boatman in it. Several lighted candles were prepared, and each of us , as geologists call it, and casting up others out of their primitive place. To the universal deluge, when "the fountains of the great deep were broken up," is this disjunction of the sup- posed original uniformity of the terrene sur- face generally attributed. These convulsions and dislocations have occasioned many cracks and fissures in a vertical direction, more or less wide, and more or less deep. It is usually in such fissures, among the rocky strata, by miners called lodes, that metallic mines are found. It is also most common that these mines are situated in mountains ; at least, when so situ- ated, they are most easily come at by man's feeble powers. The inside of these fissures is commonly METALLIC VEINS. 255 coated with a sort of rind, crystalline and earthy, which is called the capel, or wall. This seems to originate from the moisture oozing through the stratum, and coagulating on the mineral substances. Yet these regu- lar walls are seldom found but at some fathoms' depth. Veins of metallic ore are often found in lodes, not an inch wide. Yet these, if fol- lowed, frequently become very rich, and re- ward the miner's fatigue and expense, in clearing his way ; although, at first, it migjit be very unprofitable. That there must be considerable danger in digging thus deep into the recesses of the earth, may easily be supposed. One would think man was never intended to run long passages into the ground, like a mole. Yet the substances found there are not useful to 256 FOUL AIR OF MI.NES any but to him ; and some of them, as coal and salt, not to mention iron, are of prime necessity; he would be uncomfortable without them, especially in climates far removed from the equator. Descending deep into a mine, generally gives the sensation of chill; sometimes there is absolute ice : but on passing into still greater depths, the earth seems to become warmer, so that in some places the miners can scarcely bear any clothing. JTie want of pure atmospheric air, in those far distant corners of the mine, is a great in- convenience, and tends to destroy life. Air is sometimes conveyed by a pipe, the mouth of which is on the surface, and set open towards the wind; or by bellows in a simi- lar way. But the impurities which load the air in METALLIC VAPORS. 257 those deep recesses are among the most dan- gerous of the circumstances which the miner has to guard against. The vapors arising from many of the metals are very injurious to health ; the pale and sal- low complexion of most miners indicates this. Coal mines are not, in general, so noxious as those of tin; those of copper are still worse ; but the most detrimental to health are the mines of quicksilver. This injurious substance insinuates itself into the very flesh and bones of the miners ; carries off many quickly, or fills the hospitals with cases of extreme debility and suffering. As cinnabar, vitriol, bitumen, and arsenic, are most com- monly found mingled in these mines, it may rvell be supposed that the effluvia from these substances must be extremely injurious. Fre- quently, these vapors are perceived by a 17 w "258 THE CHOKE-DAMP. fragrant smell, resembling the scent of pea blossoms; this name is, therefore, applied to it, and by it the miners have warning to escape for their lives. Such as are caught by it swoon away; and, if removed to fresh air, only revive under great agonies. Carbonic acid gas, called by miners the choke-damp, is found abundantly in most places that have been long shut up ; such as cellars, wells, and especially mines. This cannot be breathed without instantaneous suffocation. Even vats in breweries are liable to it; and the loss of many lives has been the conse- quence. Charcoal fires emit it ; as many have found, who have slept in rooms which have been aired with that material. This damp, or fixed air, is very heavy, and sinks to the bottom of every reservoir wherein it exists. In a coal mine, in Scotland, some THE FIRE-DAMP. 259 * miners accidentally broke a hole into an old mine which had been long shut up ; they soon perceived their danger, and escaped with the utmost expedition. The next day, eight of them went to continue their work, without any expectation of danger. They had, how- ever, scarcely got to the bottom of the stairs, which led to their scene of opera- tion, than they all dropped down dead, as if they had been shot. The wife of one of them, on being told her husband had been suffocated, in her anxiety, ventured down to discern where he lay. She saw he was near- est to the stairs of any of them ; and, wish- ing to rescue him, if possible, she stooped to take hold of him ; but the damp seized her instantly, and she fell dead by his side. The fire-damp, or hydrogen gas, is lighter than the atmosphere, and always rises to 260 . THE FIRE-DAMP. the roof of the mine. If it gain access to a candle, it instantly ignites, with a loud and very violent explosion. Persons involved in it, are scorched more or Jess. The violence of the explosion is such, that persons who happen to be in its way in the mine, are blown out of it, to some distance ; nor can the strongest and heaviest machinery resist its force. No smell is perceived before it catches fire; but a strong scent of sulphur follows. The color of the flame is bluish, or greenish ; and it is very brilliant. It is suc- ceeded by a dark vapor, or smoke. These damps begin to arise about May, and continue during the summer, at uncertain intervals. In mines liable to the fire-damp, one mode of prevention is, never to bring the flame of a candle into them. In order, therefore, to ob- tain light without flame, with great ingenuity, SIR H. DAVY'S LAMP. 261 a large wheel is constructed, having its edge stuck full of flints ; in their way, a number of steels are placed, so that, as it revolves, a continued stream of sparks is produced; by which glimmering light, the miners are able to carry on their operations. Sparks will not set this vapor on fire. Lately, in- deed, Sir H. Davy has invented a lamp, which promises to afford great security. It has been found that the dense vapor cannot penetrate between the narrow crevices of a fine wire gauze : this is, therefore, formed into a lantern, and gives safety. That mode of safety which consists in hav- ing a stream of sparks instead of a flame, would be of no use in some cases ; where a spark would set the whole on fire. The workmen in such mines are so much afraid of this, that they take all the nails out of 262 BEGINNINGS OP MINING. their shoes, lest some spark might be acci- dentally generated. The history of mining also affords melan- choly instances of mischief done by the falling in of the earth above; when it has not been well supported. This may sometimes be guarded against by thick planks, supported as a ceiling, upon props. Again, floods of water sometimes burst in upon the men, and drown them ; perhaps, also, drown the mine itself, so that it cannot be used any more. That men should think of digging into the earth for such minerals,, seems somewhat sin- gular: yet, possibly, accident, under the gui- dance of Divine Providence, might occasion at least the first endeavor of this nature. An- cient stories tell us, that some Spanish shep- herds having set fijre to a wood, the confla- IMPROVEMENTS IN MINING. 263 gration heated the soil so much, as to melt the silver under it, and make it run into a mass. Sometimes the sea has washed away the earthy parts of the shore, so as to throw daylight upon these treasures. When men once became acquainted with these important mineral productions, they would naturally look again, and hunt in every place where there could be any hope of find- ing them. And, as they became better ac- quainted with the principles of chemistry, they became more adroit in turning to account all they found, and all they suspected to be of value. There is a sagacity, obtained only by being long accustomed to the practice, which enables some to say, with tolerable certainty, where the precious productions may be sought. Certain metals are usually found in such or 264 IMPROVEMENTS IN MINING. such kinds of soil, and never in others ; which experience establishes as a rule. The vicinity of copper ore is frequently as- certained by the harsh taste of the waters which flow near them. Or, if a piece of polished iron be immersed, where the parti- cles of copper are floating, they will affix themselves to it decidedly. Or, a piece of tallow, put in, will in a short time become green. Sometimes, in driving an adit, or road, from the lower grounds, to let off water from the mines, lodes are met with much more valuable than the one intended to be relieved. THE MINERAL CABINET. WHEN "Yes," and "No," and "O dear, how pretty I" are all the effect produced by instruction, there is reason to fear that the labor and expense bestowed upon the lesson is nearly lost. It may, indeed, happen, that the memory may be roused, years afterwards, to recollect circumstances, facts, and reason- ings, which occurred in childhood; although, apparently, they did not then make the deep : mpression wished for by the anxious tutor. When, however, we see the pupil's own mind roused to action, and that he is diligently employing himself in some project, or some operation, suggested by the instruction re- X 265 266 THE MINERAL CABINET. ceived, and of a nature to clear the subject up to his own mind, or to fasten it well in his memory, we are sure he has received benefit. It was, therefore, with considerable pleasure that Mr. Thompson, some time after their return, was introduced by James into his own study, (a closet a few feet square only,) to in- spect a mineralogical cabinet, which he had constructed. It was about two feet high, and about twelve inches wide; its depth was one inch and a half. James had been accustomed to operate for himself; he could handle the saw and the plane adroitly, and make a joint with considerable neatness. The framework was mahogany. At the top was a pediment, in which was written MINERALOGY; beneath, were four compartments of bottles, answering to the four classes into which mineral substan- THE MINERAL CABINET. 267 ces are conveniently divided ; as Earth and Stones, Salts, Combustibles, and Metallic Ores. Each of these formed a row, whether consisting of many or fewer names ; except that the last class, being more numerous, filled up three rows. He had procured a sufficient number of wide-mouth square vials, all of a size, in which he proposed to keep his specimens. Some minerals he had procured; but to fill all the bottles would be a work of time ; and some he had but small hope of obtaining. To give, however, as much completeness as he could to his cabinet, he had labelled each compartment, and also each vial. The advan- tages of vials were many ; as each subject could be distinctly seen, without danger of being lost or spoiled by incautious handling. 268 THE MINERAL CABINET. Uniformity and neatness were hereby secured, as well as conveniency of inspection. He had drawn up a written list of these, lest any of them should be disarranged; and, in order to make himself perfect in this classi- fication, he would sometimes take all the bot- tles out of their places, and intermingle them upon the table, enjoining himself, as a task, to put each of them in its proper compart- ment, and in its individual place. He had attained to so much expertness, that he al- ready could do this without making many mistakes. At a small price, and with little exertion, any one may thus obtain a general acquaint- ance with the wonderful productions found in the interior of the earth ; a sort of knowledge highly useful to many persons, and gratifying THE MINERAL CABINET. 269 to every intelligent mind, even If no absolute necessity for it should occur. As his father expressed himself much pleased with this display of his knowledge and ingenuity, James took courage to de- velop a plan much more complete, which he had in his intention ; it was, to have, not a single bottle to each genus, but a drawer, containing as many bottles as there were important specimens in each genus. This might be attained by only giving depth to his cabinet. At present, he contented himself with having a large label pasted on the hinder part of each vial, on which was written a list of the various specimens most commonly named, belonging to that genus. Thus, on the genus Silica, or Quartz, was this list : Garnet, Ruby, Topaz, Emerald, Rock Crystal, Flint, Pumice, Feldspar. . In 270 THE MINERAL CABINET. this first clasS, are many names; each be- longs indeed to a family, and under each are many specimens ; but to enlarge it thus, can only belong to a scientific mineralogist. For general knowledge, it is quite sufficient to select the most important specimens ; or such as are most likely to be mentioned in conversation, or in books of travels. He had, also, an alphabetical list of the names, with a reference to the class ; and a short account of the qualities, localities, and uses of each. We have given a representation of James's mineralogical cabinet, thinking some of our young readers might wish to make one like it. And, in order that the labels may be clearly understood, we give copies of them. The terms which follow each, express those specimens which are most commonly known, THE MINERAL CABINET. 271 or are in more general use. These names were inscribed on a larger label, behind the bottle to which it belonged. Thus his mineralogical scheme was kept complete by the labels, even should he nfever be able to obtain half the specimens ; and some of them, it was pretty certain, he would never possess: diamond and zircon for in- stance. 272 CLASS I.
