I have actually seen mules carrying to the coast, for transportation to England, a cargo of such cinders. But the first case is much the most curious. The Chilian miners were so convinced that copper pyrites contained not a particle of copper, that they laughed at the Englishmen for their ignorance, who laughed in turn, and bought their richest veins for a few dollars.
Here is a scale of gold; take it up on the needle-point. You have done it. Why? Because gold is a soft metal. Now take up this scale from your pyrites?" "I can't." "No, because iron is a hard metal. Here is another childish test a bloodstone, called by some the touchstone. Rub the pyrites on it. It colors it not a hard metal. Now rub this little nugget of pure gold I have just bought."
The sparks are struck from two lumps of iron pyrites; and as soon as the tinder has caught, it is gently blown till the fire has spread an inch around, when the pointed end of a piece of oiled wick being applied, it soon bursts into a flame, the whole process occupying a couple of minutes.
They kindled fire by striking together a piece of iron pyrites and touchwood, and never travelled without a small bag containing such materials. They fed on large birds, and killed them with the greatest ease. "I engaged one of these Indians," writes Mackenzie, "by a bribe of some beads, to describe the surrounding country upon the sand.
But the same thing has been found in the feathers of certain birds whose color is metallic green, and it has been proven that such birds pick up and swallow shining bits of copper pyrites. Why should not the ux do the same thing? Still, my only reason for believing in the existence of the bird was this single feather. I had easily proved that it belonged to no known species of bird.
Agnello's assay necessarily involved the addition of other substances for the purpose of separating the gold; and it has been suggested that the gold produced by him was itself added during this process. There is no good reason for thinking so. Pyrites often contains a minute proportion of gold.
Here the two fragments of pyrites were thrown, under orders, into the water; so that the eight villagers might know just why the whole thing was being done. Next the two men, still unconscious, were buried up to their necks. Their heads, lolling helplessly, were all that was exposed.
At one of the worst turnings we met several bullock-carts filled with iron pyrites from the copper-smelting. The custom of the drivers of these carts is to stop at the bottom of a steep bit of hill, and then put five or six pairs of oxen to draw up one cart. The process is a slow one, but is better for the oxen.
At Rancie the lias nearest the granite is not only filled with iron-ore, but charged with pyrites, tremolite, garnet, and a new mineral somewhat allied to feldspar, called, from the place in the Pyrenees where it occurs, "couzeranite." "Hornblende-schist," says Dr.
Between it and its walk of gneiss occur veins of the minerals so characteristic of the locality, and for which it has become famous serpentine, asbestos, phlozopite, gurhofite pyrites, biotite, aragonite, dolomite, tremolite, and possibly others in lesser quantity. Serpentine.
