CHAP. 31. (6.)—SILVER.

After stating these facts, we come to speak of silver ore, the next949 folly of mankind. Silver is never found but in shafts sunk deep in the ground, there being no indications to raise hopes of its existence, no shining sparkles, as in the case of gold. The earth in which it is found is sometimes red, sometimes of an ashy hue. It is impossible, too, to melt950 it, except in combination with lead951 or with galena,952 this last being the name given to the vein of lead that is mostly found running near the veins of the silver ore. When submitted, too, to the action of fire, part of the ore precipitates itself in the form of lead,953 while the silver is left floating on the surface,954 like oil on water.

Silver is found in nearly all our provinces, but the finest of all is that of Spain; where it is found, like gold, in uncultivated soils, and in the mountains even. Wherever, too, one vein of silver has been met with, another is sure to be found not far off: a thing that has been remarked, in fact, in the case of nearly all the metals, which would appear from this circumstance to have derived their Greek name of “metalla.”955 It is a remarkable fact, that the shafts opened by Hannibal956 in the Spanish provinces are still worked, their names being derived from the persons who were the first to discover them. One of these mines, which at the present day is still called Bæbelo, furnished Hannibal with three hundred pounds’ weight of silver per day. The mountain is already excavated for a distance of fifteen hundred957 paces; and throughout the whole of this distance there are water-bearers958 standing night and day, baling out the water in turns, regulated by the light of torches, and so forming quite a river.

The vein of silver that is found nearest the surface is known by the name of “crudaria.”959 In ancient times, the excavations used to be abandoned the moment alum960 was met with, and no further961 search was made. Of late, however, the discovery of a vein of copper beneath alum, has withdrawn any such limits to man’s hopes. The exhalations from silver-mines are dangerous to all animals, but to dogs more particularly. The softer they are, the more beautiful gold and silver are considered. It is a matter of surprise with most persons, that lines traced962 with silver should be black.
