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.
[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.
DISCOVERY OF SILVER IN PERU.
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.
