Chapter IX: Part 9

The basaltic pillars stand in natural colonnades, mostly above fifty feet high, in the south-western part, upon a firm basis of solid unshapen rock: above these, the stratum, which reaches to the soil of the island, varies in thickness, in proportion to the distribution of the surface into hill and valley. The pillars are of three, four and more sides; but the number of those with five and six exceeds that of the others; one of seven sides measured by Sir Joseph, was four feet and five inches in diameter.

On the west side of Staffa is a small bay, the spot where boats usually land. In this neighborhood occurs the first group of pillars: they are small, and instead of being placed upright, are recumbent on their sides, and form a segment of a circle. Further on is a small cave, above which pillars again are seen, of somewhat larger dimensions, which incline in all directions; in one place in particular, a small mass of them much resembles the ribs of a ship. Beyond the cave is the first continued range of pillars, larger than the former, and opposite to them is a small island called Bhuachaile, (pronounced Boo-sha-’lay,) or the Herdsman’s isle, separated from the main by a channel not many fathoms wide. The whole of this islet is composed of pillars without any strata above them; they are small, but by much the neatest formed of any in this quarter.

The first division of this islet, for at high tide it is divided into two parts, makes a kind of cone, the pillars converging together toward the center. On the other side the pillars are in general recumbent; and in the front, next the main, the beautiful manner in which they are joined is visible from their even extremities: all these have their transverse sections exact, and their surfaces smooth; but with the larger pillars the reverse is the case, and they are cracked in all directions.

The main island opposite the Boo-sha-’lay, and thence toward the north-west, is entirely supported by ranges of pillars, pretty erect, which, although not apparently tall, from their not being uncovered to the base, are of large diameter; at their feet is an irregular pavement, made by the upper sides of such as have been broken off. This extends as far under the water as the eye can reach.

In proceeding along the shore, the superb cavern of Fingal appears, for such is the denomination given it by the Highlanders, to whom it is known. It is supported on each side by ranges of columns, and is roofed by the bottoms of such as have been broken away. From the interstices of the roof a yellow stalactitic matter has exuded, which precisely defines the different angles; and, varying the color, tends to augment the elegance of its appearance. What adds to the grandeur of the scene, the whole cave is lighted from without, in such a manner, that the furthest extremity is plainly distinguished; while the air within, being constantly in motion, owing to the flux and reflux of the tides, is perfectly dry and wholesome, and entirely exempt from the damp vapors to which natural caverns are generally subject. The following are its dimensions:

Feet. In.
Length of the cave from the rock without, 371 6
Length of the cave from the pitch of the arch, 250 0
Breadth of the cave at the mouth, 53 7
Breadth of the cave at the further end, 20 0
Hight of the arch at the mouth, 117 6
Hight of the arch at the end, 70 0
Hight of an outside pillar, 39 6
Hight of one at the north-west corner, 54 0
Depth of water at the mouth, 18 0
Depth of water at the extremity, 9 0

The cave runs to the rock in the direction, by compass, north-north-east.

The mind can hardly form an idea more magnificent than such a space. And, indeed, speaking of the general aspect of Staffa, Sir Joseph is led, by his enthusiasm, to make the following reflections: “Compared to this, what are the cathedrals or the palaces built by man! mere models or playthings, imitations as diminutive as his works will always be, when compared to those of Nature. Where is now the boast of the architect! regularity, the only part in which he fancied himself to exceed his mistress, Nature, is here found in her possession, and here it has been left undescribed for ages. Is not this the school where the art was originally studied? And what has been added to this by the whole Grecian school? A capital to ornament the column of Nature, of which they could execute a model only; and for that very capital they were obliged to a bush of acanthus. How amply does Nature repay those who study her wonderful works.”

Such were his feelings, and in this way did he moralize, when proceeding along shore, and treading as it were on another Giant’s Causeway, he arrived at the mouth of the cave.

To the north-west are found the highest range of pillars. Here they are bare to their base, and the stratum beneath is visible, as it rises several feet above the water. The surface of it is rough, with frequent large pieces of stone sticking in it, as if half immersed. The base, when broken, appears to be composed of many heterogenous parts, and much resembles lava. Many of the floating stones are of a similar substance with the pillars, a coarse kind of basalt, less beautiful than that of the Giant’s Causeway: the color is a dirty brown. The whole of this stratum dips gradually to the south-east.

The thickness of the stratum of lava-like matter below the pillars, the hight of the pillars, and the thickness of the superincumbent stratum, at three different places westward of the mouth of the cave, beginning with the corner pillar of the cave, are described as follows by Sir Joseph Banks:

Feet. In. Feet. In. Feet. In.
Stratum below, 11 0 17 1 19 8
Hight of pillars, 54 0 50 0 55 1
Stratum above, 61 6 51 1 54 7

The stratum above the columns is uniformly the same, consisting of numberless small pillars, bending and inclining in all directions, sometimes so irregularly, that the stones can only be said to have an inclination to assume a columnar form; in others more regularly; but never breaking into, or disturbing the stratum of large pillars, whose tops keep everywhere an uniform line. On the opposite side of the island is a cavern, called Oua-na-scarve, or the Cormorant’s cave; here the stratum under the pillars is lifted up very high, and the pillars are considerably less than at the north-west side. Beyond, a bay cuts deep into the island, rendering it not more than a quarter of a mile across. On the sides of this bay, especially beyond a little valley, which almost divides the island, are two stages of small pillars, with a stratum between, exactly resembling that above, formed of innumerable little pillars shaken out of their places, and leaning in all directions. Beyond this, the pillars totally cease. The rock is of a dark-brown stone, without regularity, from the bay along the south-east end of the island; beyond which, a disposition to columnar formation is again manifested, extending from the west side, but in an irregular manner, to the bending pillars first described.

OTHER GROTTOS AND CAVERNS.

There are few countries which have not to boast of a variety of natural excavations; and these have, from their extent, structure, and the curious phenomena they exhibit, in the formation of petrifactions, &c., been at all times objects of popular attention. Among those particularly deserving of notice are the following.

The volcanic country bordering on Rome, is peculiarly diversified by natural cavities of great extent and coolness; on which last account it is related by Seneca, that the Romans were accustomed to erect seats in their vicinity, to enjoy their refreshing chillness in the summer season. He gives a particular account of two such grottos belonging to the villa of Vatia; and it was in a place of this kind that Tiberius was nearly destroyed while at supper. Its roof suddenly gave way, and buried several of his attendants in its ruins; which so alarmed the others, that they fled and abandoned the emperor, with the exception of Sejanus, who, stooping on his hands and knees, and covering the body of Tiberius with his own, received all the stones which fell at that part from the roof, insomuch that, although he himself sustained considerable injury, the emperor escaped unhurt.

The grottos of the Cevennes mountains, in lower Languedoc, are both numerous and extensive. The principal one is not to be explored without much precaution, and without a safe guide. The entrance, which is low and narrow, leads to a spacious amphitheater, the petrifactions hanging from the roof of which have a most splendid effect by the light of torches. Hence the visitor has to descend to several chambers, one of which is named the Chamber of the Winds; another, of Echo; another, of the Cascade; another, again, of the Statue, &c.; on account of their exhibiting these different phenomena. In the grotto of Valori, at a small distance, the different natural curiosities which are to be found at every step, may be viewed at leisure, and without apprehension, as the visitor never loses sight of the light at the entrance, and is, therefore, not under any dread of not returning in safety. Here he is gratified by a view of the most singular petrifactions, representing flowers, fruits, bee-hives, and, in short, a variety of objects, in many of which the resemblance is nearly as accurate as if they had been sculptured.

In a wood, about five leagues from Besançon, in the province of France called Franche Comte, an opening, formed by two masses of rock, leads to a cavern more than nine hundred feet beneath the level of the country. It is in width sixty feet, and eighty feet high at the entrance, and exhibits inside an oval cavity of one hundred and thirty-five feet in breadth, and one hundred and sixty-eight in length. To the right of the entrance is a deep and narrow opening, bordered with festoons of ice, which, distilling in successive drops on the bottom of the cavern, form a mass of about thirty feet in diameter. A similar one, but somewhat smaller, produced by the water which drips in less abundance from the imperceptible fissures in the roof, is seen on the left. The ground of the cavern is perfectly smooth, and covered with ice eighteen inches thick; but the top, on the outside, is a dry and stony soil, covered with trees, and on a level with the rest of the wood. The cold within this cavern is so great, that, however warm the external atmosphere may be when it is visited, it is impossible to remain in it for any length of time.

These natural ice-houses are not unfrequent in France and Italy, and supply this agreeable luxury at a very cheap rate. Thus, in the same province, in the vicinity of Vesoul, is a cavern which, in the hot season, when it is eagerly sought, produces more ice in one day, than can be carried away in eight. It measures thirty-five feet in length, and in width sixty. The large masses of ice which hang pendent from the roof, have a very pleasing effect. When mists are observed in this cavern, they are regarded by the neighboring peasantry as infallible prognostics of rain; and it is worthy of observation, that although the water in the interior is always frozen in the summer, it becomes liquid in the winter season.

A grotto near Douse, also in Franche Comte, forms a similar ice-house, and is remarkable on account of the various forms of its congelations, which represent a series of columns, sustaining a curious vault, which appears to be carved with figures of men, animals, trees, &c.

The caverns of Gibraltar are numerous, and several of them of great extent. The one more particularly deserving attention is called St. Michael’s cave, situated on the southern part of the mountain. Its entrance is one thousand feet above the level of the sea, and is formed by a rapid slope of earth, which has fallen in at various periods, and which leads to a spacious hall, incrusted with spar, and apparently supported in the center by a large stalactitical pillar. To this succeeds a long series of caves, of difficult access. The passages leading from the one to the other are over precipices, which can not be passed without the aid of ropes and scaling-ladders. Several of these caves are three hundred feet beneath the upper one; but at this depth the smoke of the torches carried by the guides becomes so disagreeable, that the visitor is obliged reluctantly to give up the pursuit, and leave other caves unexplored. In these cavernous recesses, the process and formation of the stalactites is to be traced, from the flimsy quilt-like cone suspended from the roof, to the robust trunk of a pillar, three feet in diameter, which rises from the floor, and seems intended by nature to support the roof from which it originated.

The variety of forms which this matter takes in its different situations and directions, renders this subterraneous scenery strikingly grotesque, and in some places beautifully picturesque. The stalactites of these caves, when near the surface of the mountain, are of a brownish yellow color; but, in descending toward the lower caves, they lose the darkness of their color, which is by degrees shaded off to a pale yellow. Fragments are broken off, and, when wrought into different forms, and polished, are beautifully streaked and marbled.

About seven English miles from Adlersberg, in Carniola, is a remarkable cavern, named St. Magdalen’s cave. The road being covered with stones and bushes, is very painful; but the great fatigue it occasions is overbalanced by the satisfaction of seeing so uncommon a cavern. The visitor first descends into a hole, where the earth appears to have fallen in for ten paces, when he reaches the entrance, which resembles a fissure caused by an earthquake, in a huge rock. The torches are here lighted, the cave being extremely dark. This wonderful natural excavation is divided into several large halls, and other apartments. The vast number of pillars by which it is ornamented give it a superb appearance, and are extremely beautiful: they are as white as snow, and have a semi-transparent luster. The bottom is of the same materials; insomuch that the visitor may fancy he is walking beneath the ruins of some stately palace, amid noble pillars and columns, partly mutilated, and partly entire. Sparry icicles are everywhere seen suspended from the roof, in some places resembling wax tapers, which, from their radiant whiteness, appear extremely beautiful. All the inconvenience here arises from the inequality of the surface, which may make the spectator stumble while he is contemplating the beauties above and around him.

In the neighborhood of the village of Szelitze, in Upper Hungary, there is a very singular excavation. The adjacent country is hilly, and abounds with woods, the air being cold and penetrating. The entrance into this cavern, fronting the south, is upward of one hundred feet in hight, and forty-eight in breadth, consequently sufficiently wide to receive the south wind, which here generally blows with great violence; but the subterraneous passages, which consist entirely of solid rock, winding round, stretch still farther to the south. As far as they have been explored, their hight has been found to be three hundred feet, and their breadth about one hundred and fifty. The most inexplicable singularity, however, is, that in the midst of winter the air in this cavern is warm; and when the heat of the sun without is scarcely supportable, the cold within is not only very piercing, but so intense, that the roof is covered with icicles of the size of a large cask, which, spreading into ramifications, form very grotesque figures. When the snow melts in spring, the inside of the cave, where its surface is exposed to the south sun, emits a pellucid water, which congeals instantly as it drops, and thus forms the above icicles: even the water which falls from them on the sandy ground, freezes in an instant. It is observed, that the greater the heat is without, the more intense is the cold within; so that, in the dog-days, every part of this cavern is covered with ice. In autumn, when the nights become cold, the ice begins to dissolve, insomuch that, when the winter sets in, it is no longer to be seen; the cavern then is perfectly dry, and has a mild and gentle warmth. It is, therefore, not surprising that swarms of flies, gnats, bats, owls, and even great numbers of foxes and hares, resort thither, as to their winter retreat, and remain there till the return of spring.

MINES, METALS, GEMS, &C.

“Through dark retreats pursue the winding ore,
Search nature’s depths, and view the boundless store;
The secret cause in tuneful numbers sing,
How metals first were framed, and whence they spring:
Whether the active sun, with chymic flames,
Through porous earth transmits his genial beams
With heat impregnating the womb of night
The offspring shines with his paternal light:
Or whether, urged by subterraneous flames,
The earth ferments and flows in liquid streams;
Purged from their dross, the nobler parts refine,
Receive new forms, and with new beauty shine:
Or whether by creation first they sprung,
When yet unpoised the world’s great fabric hung:
Metals the bases of the earth were made,
The bars on which its fixed foundation’s laid:
All second causes they disdain to own,
And from the Almighty’s fiat sprung alone.”

The transition from the caverns and caves of the earth, to its MINES, and the various metals and gems they contain, is both natural and easy; and having dwelt on the former, we propose next to advert to the latter. By the word “_mines_” we understand those excavations, in which metals, minerals and precious stones are sought and found; and according to the substances which they yield they are variously spoken of as “gold mines,” “silver mines,” “lead mines,” &c., &c. The richest and most celebrated gold and silver mines are those of Mexico and Peru, in South America, and those lately discovered in California and Australia. Iron mines are more abundant, or at least more abundantly worked, in Europe than elsewhere, though the rapid increase of iron mining in the United States gives promise that our country may in this respect some day rival the old world. Copper mines have been found chiefly in England, Sweden and Denmark; and of late years copper has been found to be abundant in the region of our northern lakes. Lead and tin mines are numerous in England, the latter chiefly in the county of Cornwall; and lead is also found in abundance in the United States. Quicksilver mines abound principally in Hungary, Spain, Friuli, in the Venetian territories, and in Peru. Diamond mines are mainly in Brazil, and some in the East Indies; and salt mines are in Poland.

To explain the structure of mines, it should be observed that the internal parts of the earth, as far as they have been investigated, do not consist of any one uniform substance, but of various strata, or beds of substances, extremely different in their appearances, specific gravities and chemical qualities, one from another. Neither are these strata similar to each other, either in their nature or appearance, in different countries; insomuch that, even in the short extent of half a mile, sometimes, the strata will be found quite different in one from what they are in another place. As little are they the same either in depth or solidity. Innumerable cracks and fissures are found in all of them; and these again are so entirely different in size and shape, that it is impossible to form any inference from what may have been met with, relative to that which remains to be explored.

In Cornwall, the most common opinion entertained by the miners, is, that crude and immature minerals nourish and feed the ores with which they are intermixed in the mines; and that the minerals themselves will, in process of time, be converted into ores productive of those metals to which they have the nearest affinity, and with which they are most closely intermingled. And a distinguished professor, who is familiar alike with geology, chemistry and mineralogy, after visiting the mining districts of California, has given it as his opinion, that gold is constantly being formed there, by some powerful agency of nature which is still and steadily at work. And as a somewhat kindred view, Mr. Price, in his mineralogy of Cornwall, thinks it is most reasonable to conclude, that metals were made and planted in veins, at, or very soon after, the creation of the world; but that, in common with all other matter, they are subject to a degree of fluctuation, approaching to, or receding from, their ultimate degree of perfection, either quicker or slower, as they are of greater or less solid and durable frame and constitution. He supposes in every metal a peculiar magnetism, and an approximation of particles of the same specific nature, by which its component principles are drawn and united together; more particularly the matters left by the decomposition of the waters passing through the contiguous earths or strata, and deposited in their proper nidus or receptacle, until, by the accretion of more or less of its homogeneous particles, the metallic vein may be denominated either rich or barren.

DIAMOND MINES.

The word _diamond_, is supposed to be a corruption of the word _adamant_, in allusion to the great hardness of this gem, which is the most valuable of all the precious stones. Diamonds were originally discovered in Bengal, and in the island of Borneo; and about the year 1720, were found in Brazil. They are found of all colors; and those which are colorless, or of some decided tint, are most esteemed, though the latter kind are very rare. Those which are slightly discolored are the least valuable.

The specific gravity of the diamond, is, to that of water, in the proportion of about three and a half to one. It is the hardest of all known substances, and can only be cut and polished by its own dust or powder. The art of splitting or cutting and polishing this gem, though probably of remote antiquity in Asia, was first introduced into Europe in 1486, by Louis Berghan, of Bruges, who accidentally discovered that by rubbing two diamonds together, their surfaces might be rendered smooth. And the fine powder which is rubbed off by such friction, serves to grind and polish them. The diamond is of the nature of _charcoal_, or pure carbon, and is combustible: under the blow-pipe it burns away in a blue, lambent flame.

The high value attached to diamonds does not depend so much on their beauty and hardness, as on their great scarcity, and the labor and expense necessary in procuring them. Hitherto they have been observed only in the torrid zone; and Brazil is the only part of America in which they have been found. The historical account of their discovery in that country is as follows. Near the capital of the territory of Serro do Frio flows the river Milho Verde, where it was the custom to dig for gold, or rather to extract it from the alluvial soil. The miners, during their search for gold, found several diamonds, which they were induced to lay aside in consequence of their particular shape and great beauty, although they were ignorant of their intrinsic value.

The diamond works on the river Jigitonhonha are described by Mr. Mawe as the most important in the Brazilian territory. The river, in depth from three to nine feet, is intersected by a canal, beneath the head of which it is stopped by an embankment of several thousand bags of sand, its deeper parts being laid dry by chain-pumps. The mud is now washed away, and the =cascalhao=, or earth which contains the diamonds, dug up, and removed to a convenient place for washing. The process, which is as follows, is seen in the cut on the next page. A shed, consisting of upright posts which support a thatched roof, is erected in the form of a parallelogram, in length about ninety feet, and in width forty-five. Down the middle of its area a current of water is conveyed through a canal covered with strong planks, on which the earth is laid to the thickness of two or three feet. On the other side of the area is a flooring of planks, from twelve to fifteen feet in length, imbedded in clay, extending the whole length of the shed, and having a gentle slope from the canal. This flooring is divided into about twenty compartments, or troughs, each about three feet wide, by means of planks placed on their edges; and the upper ends of these troughs communicate with the canal, being so formed that water is admitted into them between two planks about an inch separate from each other. Through this opening the current falls about six inches into the trough, and may be directed to any part of it, or stopped at pleasure, by means of a small quantity of clay. Along the lower ends of the troughs a small channel is dug, to carry off the water.

On the heap of earth, at equal distances, three high chairs are placed for the overseers, who are no sooner seated than the negroes enter the troughs, each provided with a rake of a peculiar form, and having a short handle, with which he rakes into the trough from fifty to eighty pounds’ weight of the earth. The water being then allowed to pass in by degrees, the earth is spread abroad, and continually raked up to the head of the trough, so as to be kept in constant motion. This operation is continued for a quarter of an hour, when the water begins to run clearer; and, the earthy particles having been washed away, the gravel-like matter is raked up to the end of the trough. At length the current flowing quite clear, the largest stones are thrown out, and afterward those of an inferior size; the whole is then examined with great care for diamonds. When a negro finds one, he instantly stands upright, and claps his hands; he then extends them, holding the gem between the fore-finger and the thumb. An overseer receives it from him, and deposits it in a bowl, suspended from the center of the structure, and half filled with water. In this vessel all the diamonds found in the course of the day are deposited, and at the close of the work are taken out and delivered to the principal overseer, who, after they have been weighed, registers the particulars in a book kept for that purpose.

When a negro is so fortunate as to find a diamond of the weight of seventeen carats and a half, the following ceremony takes place: he is crowned with a wreath of flowers, and carried in procession to the administrator, who gives him his freedom by paying his owner for it. He also receives a present of new clothes, and is permitted to work on his own account. For small stones proportionate premiums are given; while many precautions are taken to prevent the negroes from stealing the diamonds, with which view they are frequently changed by the overseers, lest these precious gems should be concealed in the corners of the troughs. When a negro is suspected of swallowing a diamond, he is confined in a solitary apartment, and means taken to bring the gem to light.

In the East Indies, the kingdom of Golconda, extending two hundred and sixty miles along the bay of Bengal, and having a breadth of two hundred miles from east to west, abounds in diamond mines. They are chiefly in the vicinity of the rocky hills and mountains which intersect the country, and in the whole of which diamonds are supposed to be contained. In several of the mines they are found scattered in the earth, within two or three fathoms of the surface, and in others are met with in a mineral substance in the body of the rocks, forty or fifty fathoms deep. The laborers having dug five or six feet into the rock, soften the stone by fire, and proceed till they find the vein, which often runs two or three furlongs under the rock. The earth being brought out and carefully searched, affords stones of various shapes, and of a good water. This earth is of a yellowish, and sometimes of a reddish color, frequently adhering to the diamond with so strong a crust that the separation becomes difficult.

To find the diamonds, the workmen form a cistern of a kind of clay, with a small vent on one side, a little above the bottom; in this vent they place a plug, and throwing into the cistern the earth they have dug, pour in water to dissolve it. They then break the clods, and stir the wet earth in the cistern, allowing the lighter part to be carried off in the form of mud, when the vent-hole is opened to let out the water. They thus continue washing, until what remains in the cistern is pretty clean; and then, in the middle of the day, when the sun shines bright, carefully look over all the sand, at which practice they are so expert, that the smallest stone can not escape them. The brightness of the sun being reflected by the diamonds, aids them in their research, which would be foiled if a cloud were to intervene.

The largest known diamond was found in Brazil, and belongs to the king of Portugal. It weighs sixteen hundred and eighty carats; and, although uncut, it is valued at the enormous sum of two hundred and twenty-four millions sterling, which gives an estimate of nearly eighty pounds sterling for each carat, the multiplicand of the square of its whole weight being taken. The one next in magnitude and value, is probably that mentioned by Tavernier, in possession of the Great Mogul. It was found in Golconda in 1550; is of the size of half a hen’s egg, and is said to weigh nine hundred carats. This diamond is the same as the famous “_Koh-i-noor_,” or “Mountain of Light,” now belonging to the queen of England, and which attracted so much attention in the great exhibition at London, in 1851. The one supposed to be next in value, is that belonging to the crown jewels of Russia, which weighs seven hundred and seventy-nine carats, and has been estimated at five millions sterling. But perhaps the most perfect and beautiful diamond hitherto found, is the one known as the Pitt diamond, which was brought from India by a gentleman of that name, who sold it to the Duke of Orleans for one hundred thousand pounds sterling. It was worn by Bonaparte in the hilt of his sword. It weighs about one hundred and thirty-six carats, or five hundred and forty-four grains. It ought, however, to be observed, that these estimates, founded on the magnitude and brilliancy of the gems, are very different from the prices which the most princely fortunes can afford to pay for them. The Russian diamond cost about one hundred and thirty five thousand pounds sterling; and the one called the Pitt or Regent, although it weighed one hundred and thirty-six carats only, was, on account of its greater brilliancy, purchased of a Greek merchant, for one hundred thousand pounds sterling. Several other large diamonds are preserved in the cabinets of the sovereigns and princes of Europe.

Why such immense value should be attached to diamonds, in all civilized countries, and by a kind of common consent, is one of those singular things that seem inexplicable. That a magnificent house, with a large estate, and the means of living not only in comfort but splendor, should be set in competition with, and even deemed inadequate to the purchase of, a transparent crystallized stone, not half the size of a hen’s egg, seems almost a kind of insanity! If for the mere consciousness of possessing a diamond of less than the weight of an ounce, any private gentleman were to pay four hundred and fifty thousand dollars in ready money, and an annuity of twenty thousand dollars besides, he would probably be thought beside himself. And yet not only was the above sum given, but a patent of nobility into the bargain, by the empress Catharine, of Russia, for the famous diamond “Nadir Shah.” In this case, however, though the seller acquired much, the purchaser did not suffer any personal privation; and in reality, notwithstanding the costliness and high estimation of diamonds, they are not put in competition with the substantial comforts and conveniences of life. Among ornaments and luxuries, however, they unquestionably occupy, and have ever occupied, the highest rank. Even Fashion, proverbially capricious as she is, has remained steady in this, one of her earliest attachments, during probably three or four thousand years. There must be, therefore, in the nature of things, some adequate reason for this universal consent; which becomes a curious object of inquiry.

The utility of the diamond, great as it is in some respects, enters for little or nothing into the calculation of its price; at least all that portion of its value which constitutes the difference between the cost of an entire diamond and an equal weight of diamond powder, must be attributed to other causes.

The beauty of this gem, depending on its unrivaled luster, is, no doubt, the circumstance which originally brought it into notice, and still continues to uphold it in the public estimation; and certainly, notwithstanding the smallness of its bulk, there is not any substance, natural or artificial, which can sustain any comparison with it in this respect. The vivid and various refractions of the opal, the refreshing tints of the emerald, the singular and beautiful light which streams from the six-rayed star of the girasol, the various colors, combined with high luster, which distinguish the ruby, the sapphire, and the topaz, beautiful as they are on a near inspection, are almost entirely lost to a distant beholder; whereas the diamond, without any essential color of its own, imbibes the pure solar ray, and then reflects it, either with undiminished intensity, too white and too vivid to be sustained for more than an instant by the most insensible eye, or decomposed by refraction into those prismatic colors, which paint the rainbow, and the morning and evening clouds, combined with a brilliancy which hardly yields to that of the meridian sun. Other gems, inserted into rings and bracelets, are best seen by the wearer; and if they attract the notice of the bystanders, divide their attention, and withdraw those regards which ought to be concentered on the person, to the merely accessory ornaments. The diamond, on the contrary, whether blazing on the crown of state, or diffusing its starry radiance from the breast of titled merit, or “in courts of feasts and high solemnities,” wreathing itself with the hair, illustrating the shape and color of the neck, and entering ambitiously into contest with the lively luster of those eyes that “rain influence” on all beholders, blends harmoniously with the general effect, and proclaims to the most distant ring of the surrounding crowd, the person of the monarch, of the knight, or of the beauty.

Another circumstance tending to enhance the value of the diamond is, that although small stones are sufficiently abundant to be within the reach of moderate expenditure, and therefore afford, to all those who are in easy circumstances an opportunity to acquire a taste for diamonds, yet those of a larger size are, and ever have been, rather rare; and of those which are celebrated for their size and beauty, the whole number, at least in Europe, scarcely amounts to half a dozen, all of them being in possession of sovereign princes. Hence, the acquisition even of a moderately large diamond, is what mere money can not always command; and many are the favors, both political and of other kinds, for which a diamond of a large size, or of uncommon beauty, may be offered as a compensation, where its commercial price, in money, neither can be tendered, nor would be received. In many circumstances also, it is a matter of no small importance for a person to have a considerable part of his property in the most portable form possible; and in this respect what is there that can be compared to diamonds, which possess the portability, without the risk of bills of exchange? It may further be remarked, in favor of this species of property, that it is but little liable to fluctuation, and has gone on pretty regularly increasing in value, insomuch that the price of stones of good quality is considerably higher than it was some years ago.

The art of cutting and polishing diamonds, has a twofold object; first, to divide the natural surface of the stone in a symmetrical manner by means of highly polished polygonal planes, and thus to bring out, to the best advantage, the wonderful refulgence of this beautiful gem; and, secondly, by cutting out such flaws as may happen to be near the surface, to remove those blemishes which materially detract from its beauty, and consequently from its value. The removal of such flaws is a matter of great importance; for, owing to the form in which the diamond is cut, and its high degree of refrangibility, the smallest fault is magnified, and becomes obtrusively visible to all. For this reason, also, it is by no means an easy matter, at all times, to ascertain whether a flaw is or is not superficial; and a person with a correct and well-practiced eye, may often purchase to great advantage, stones which appear to be flawed quite through, but which are in fact only superficially blemished.

Before leaving the subject of diamonds, it may be well to notice some other valuable stones that are much sought and prized for ornament. One of these is the _oriental ruby_. This, in its most esteemed color, is pure carmine, or a blood-red of considerable intensity, forming, when well polished, a blaze of the most exquisite and unrivaled tint. It is, however, more or less pale, and mixed with blue in various proportions; and hence it occurs rose-red, and reddish-white, crimson, peach-blossom red, and lilac-blue, the latter variety being named the _oriental amethyst_. It is a native of Pegu, and is said to be found in the sand of certain streams near the capital of the country; and it also occurs, with the sapphire, in the sands of the rivers of Ceylon. A ruby which is perfect both in color and transparency, is much less common than a good diamond; and when of the weight of three or four carats, is even more valuable than a diamond of the same size. The king of Pegu, and the monarchs of Asia and Siam, monopolize the finest rubies, in the same way as the sovereigns of India make a monopoly of diamonds. The finest ruby in the world is in possession of the first of these kings. Its purity has passed into a proverb, and its worth, when compared with gold, is inestimable. The dubah of Deccan, also, possesses a remarkably fine one, which is a full inch in diameter. The princes of Europe can not boast of any rubies of first-rate magnitude.

The _oriental sapphire_ ranks next in value to the ruby. When it is perfect, its color is a clear and bright Prussian blue, united to a high degree of transparency. The _astoria_ or _star-stone_, is a remarkable variety of this beautiful gem: it is semi-transparent, with a reddish purple tinge. And beside these, there are the _red_ sapphire, often called the oriental ruby, and the _yellow_ sapphire, which is called the oriental topaz. And in addition to these precious stones, or gems, there are also the _emerald_, of a beautiful green color; the _topaz_, which is of a yellow or light wine-color, and which by being heated, sometimes becomes rose-red, so as to be passed off as a ruby; the _jasper_ and _chalcedony_, which are of various colors; the _onyx_, which is a regularly banded agate, much prized for cameos, especially where the colors are very distinct and different; the _cornelian_, which is properly a red or flesh-colored chalcedony, much valued for seal-stones, &c.; and the _blood-stone_, or _heliotrope_, which is deep green, and somewhat translucent, and variegated by blood-red spots: all of which are much used in the various departments of jewelry.

We have reserved for this place, a notice of the hot-well at Clifton, England, which would have been mentioned in connection with the Geysers and other hot springs, but from its connection with the beautiful crystals known as _Bristol stones_ or _diamonds_, some of which are so hard as to cut glass, and are exceedingly clear, colorless and brilliant. When set in rings, in their natural state, these stones often appear of as high a polish and luster, as if they had been wrought by the most skillful lapidary.

The warm spring, or fountain, in the vicinity of which they are found, is called the _hot-well_. It is in the parish of Clifton, and is so copious as to discharge sixty gallons of water in a minute. It rises forcibly from an opening in the solid rock, at about twenty-six feet below high-water mark. On its immediate influx from the rock, the water is much warmer than when it is pumped up for drinking, for it is raised by pumps some thirty feet. Its qualities in a medicinal point of view are supposed to be valuable; but it is not on this point that we propose to dwell, and therefore we pass on to the rocks in the neighborhood, near which the _Bristol stones_ are found. Just below the hot-well, there rises a noble range of hills, which are not more remarkable for their hight, than for their being equally so on both sides the river, the strata in some places answering on each side for about a mile and a half in a serpentine course. These constitute one of the greatest natural curiosities in England. The rock beyond the hot-well, and on the same side, is named St. Vincent’s, a chapel dedicated to that saint having been formerly built on its summit. It is in hight three hundred feet, and has a majestic appearance. It supplies the naturalist with many curious fossils, the botanist with a variety of scarce plants, the antiquary with the remains of a Roman camp, and the less curious inquirer with a view of a most dreadful and surprising precipice.

The rocks in general, when broken up, are of a dusky red, brown or chocolate colored marble, very hard and close-grained, and which, on being struck with a hammer, emit a strong sulphureous smell. It will bear a polish equal to any foreign marble; and, when sawed into slabs and polished, appears beautifully variegated with veins of white, bluish-gray, or yellow. It is often employed for chimney-pieces; but it is principally used for making lime, for which purpose there is no stone in England so well calculated, nor is there any lime so strong, fine, and white, which excellent qualities occasion great demand for foreign consumption.

Here, and in the vicinity, laborers are daily employed in blowing up the rocks with gunpowder, by which process vast fragments are frequently thrown down, and repeatedly strike the precipice with a dreadful crash, which, combined with the loud report of the explosion, reëchoed from side to side by the lofty cliffs, makes a noise resembling thunder, for which it is frequently mistaken by strangers. It is the opinion of the greater part of those who have viewed these rocks, that they were once united, and were separated by some terrible convulsion of nature. A bridge of one arch, from rock to rock, over the Avon, has long been in contemplation; but if the blowing up of these rocks should still be persisted in, the design will be rendered impracticable. This is the more to be regretted, because stone of the same quality is to be procured lower down the river.

Now it is in the fissures and cavities of these rocks, that the beautiful crystals called _Bristol stones_, or _diamonds_, already mentioned, are found. They are clear and brilliant, and being without color, so richly and brilliantly reflect the light, as to be almost next to the diamond in appearance, and are often palmed off on the unpracticed for the latter gem. They are extensively used in many of the plainer kinds of jewelry, and when set over gold-leaf, or thin paper of delicate tinges, are often made closely to resemble some of the richest gems known.

GOLD AND SILVER MINES.[4]

The mines of La Plata, so denominated on account of the abundance of silver they contain, are chiefly situated in the provinces which were formerly attached to the Spanish viceroyalty of Rio de la Plata; but which, since the South American states revolted from the mother country, have been included in the republic of Bolivia, or Upper Peru as it is sometimes called. With the exception of Mexico, Bolivia is the richest country in silver which has yet been discovered, and contains innumerable mines both of that metal and of gold. All its northern provinces teem with mineral opulence; and those of Laricaja and Carabaya, have been distinguished by the production of the latter, and still nobler metal, in its virgin state. In consequence, however, of the recent political convulsions, mining, once the richest source of revenue, is in a depressed state; many of the mines being filled with water and totally neglected.

Footnote 4:

The account of the mines of South America and Mexico is mostly from
Humboldt, and as will be obvious to the reader, has reference in many
things to their past history and progress, rather than to their
present condition.

The mountain of Potosi formerly produced weekly about five thousand marks of silver, that is, from thirty to forty thousand dollars; a surprising produce, when it is considered that it has been wrought since 1545, at which time it was accidentally discovered by an Indian, or native, as represented in the cut. In hunting some goats, he slipped from a slight elevation, and to save himself caught hold of a shrub, which coming away from the ground, laid bare the silver at its root. At the commencement it was still more abundant, and the metal was dug up in a purer state.

The silver was often found in shoots like roots, imbedded in the earth. Six thousand Indians were sent every eighteen months, from the provinces of the viceroyalty, to work this mine. The expedition was called _mita_; and these Indians, having been enrolled and formed into parties, were distributed by the governor of Potosi, and received a small daily stipend, (equal to about thirty-four cents of our currency,) until the period of their labor was completed. They were thus doomed to a forced service, nothing less than slavery, so long as it lasted, which the Spaniards have endeavored to justify by the plea that laborers could not otherwise be procured.

Lumps of pure gold and silver, called =papas=, from their resemblance to the potato, were often found in the sands. The poor likewise occupied themselves in =lavaderos=, or in washing the sands of the rivers and rivulets, in order to find particles of the precious metals.

To compensate for the mines rendered useless by the irruption of water, or other accidents, rich and new ones were daily discovered. They were all found in the chains of mountains, commonly in dry and barren spots, and sometimes in the sides of the =quebredas=, or astonishing precipitous breaks in the ridges. However certain this rule might be in the region of Bolivia, it was contradicted in that of Peru, where, at three leagues’ distance from the Pacific ocean, not far from Tagna, in the province of Arica, there was discovered the famous mine of Huantajaya, in a sandy plain at a distance from the mountains, of such exuberant wealth that the pure metal was cut out with a chisel. From this mine a large specimen of virgin silver is preserved in the royal cabinet of natural history at Madrid. It attracted a considerable population, although neither water nor the common conveniences for labor could be found there, neither any pasturage for the cattle.

In the mint of Potosi, about six millions of dollars were annually coined; and the mines of the old viceroyalty of La Plata, taken collectively, are reckoned to have yielded about sixteen millions.

The mines of Mexico, or what was formerly called New Spain, have been more celebrated for their riches than those of La Plata, notwithstanding which they are remarkable for the poverty of the mineral they contain. A quintal, or sixteen hundred ounces of silver ore, affords, at a medium, not more than three or four ounces of pure silver, about one-third of what is yielded by the same quantity of mineral in Saxony. It is not, therefore, on account of the richness of the ore, but from its abundance and the facility of working it, that these mines have been so much superior to those of Europe.

The fact of the small number of persons employed in working them, is not less contrary to the commonly received opinion on this subject. The mines of Guanaxuato, infinitely richer than those of Potosi ever were, afforded from 1706 to 1803, nearly forty millions of dollars in gold and silver, or very nearly five millions of dollars annually, being somewhat less than one-fourth of the whole quantity of gold and silver from New Spain; notwithstanding which, these mines, productive as they were, did not employ more than five thousand workmen of every description. In Mexico, the labor of the mines was perfectly free, and better paid than any other kind of industry, a miner earning from five to five dollars and a half weekly, while the wages of the common laborer did not exceed a dollar and a half. The =tenateros=, or persons who carried the ore on their backs, from the spot where it was dug out of the mine, to that where it was collected in heaps, had a sum equal to a dollar and ten cents for a day’s work of six hours. Neither slaves, criminals, nor forced laborers, were employed in the Mexican mines.

In consequence of the clumsy, imperfect and expensive mode of clearing them from water, several of the richest of these mines have been overflowed and abandoned; while the lack of method in the arrangement of the galleries, and the absence of lateral communications, have added to the risk, and greatly increased the expense of working them. Labor has not been, as in the working of the European mines, abridged, nor the transportation of materials facilitated. When new works were undertaken, a due consideration was not bestowed on the preliminary arrangements; and they were always conducted on too large and expensive a scale.

More than three-fourths of the silver obtained from America is extricated from the ore by means of quicksilver, the loss of which, in the process of amalgamation, is immense. The quantity that used to be consumed annually in Mexico alone, was about sixteen thousand quintals; and in the whole of South America, about twenty-five thousand quintals were yearly expended, the cost of which there, has been estimated at more than a million dollars. The greater part of this quicksilver, in later years, was furnished by the mine of Almaden in Spain, and that of Istria in Carniola, the celebrated quicksilver mine of Huancavelica in Peru, having greatly fallen off in its produce since the sixteenth century, when it was highly flourishing. The prosperity of the silver mines, both in Mexico and Peru, therefore depended very much on the supplies of quicksilver from Spain, Germany and Italy; for such was the abundance of the ore in those provinces, that apparently the only limit to the amount of silver obtained there, was the want of mercury for amalgamation.
