When the armed soldiers scattered from before the door of the smelting-furnace, he had boldly waded through the burning spirit; he knew very well that it could not set fire to clothing immediately and he took care to hold his hands in front of his eyes to save himself from being blinded. He tore the door open and hastily vanished through it.

Like their kindred in Britain, they had successfully exploited the mineral treasures of the country, and their skill as miners is eloquently upheld by the mute witness of age-old cinder-heaps by which are found the once busy bronze hammer and the apparatus of the smelting-furnace, speaking of the slow but steady smith-toil upon which the foundation of civilization arose.

We set out early in the morning, and by mid-day reached the ravine of Paypote, where there is a tiny rill of water, with a little vegetation, and even a few algarroba trees, a kind of mimosa. From having firewood, a smelting-furnace had formerly been built here: we found a solitary man in charge of it, whose sole employment was hunting guanacos.

At these words, however, the adventurer recovered himself. He saw a pitiless enemy and a troop of armed men hastening to the door of the smelting-furnace and that way of refuge was consequently closed. The same instant an infernal idea occurred to him. Hastily snatching up a burning torch from the altar with a couple of vigorous bounds he approached the smelting-furnace.

Sticks were plentiful for firewood, so that it was a good place to bivouac for us; but for the poor animals there was not a mouthful to eat. June 11th. We rode without stopping for twelve hours till we reached an old smelting-furnace, where there was water and firewood; but our horses again had nothing to eat, being shut up in an old courtyard.

Thus, in analyzing the crust of the globe, we find at once two kinds of rocks, the respective work of fire and water: the first poured out from the furnaces within, and cooling, as one may see any mass of metal cool that is poured out from a smelting-furnace to-day, in solid crystalline masses, without any division into separate layers or leaves; and the latter in successive beds, one over another, the heavier materials below, the lighter above, or sometimes in alternate layers, as special causes may have determined successive deposits of lighter or heavier materials at some given spot.

Thus, if twenty parts had been the weight of tin ore, the result might perhaps have been fourteen parts of metal and six parts of dross. And now, gentlemen, having explained to you the testing process, if you will follow me, I will show you the opening of one of our furnaces. The smelting-furnace just shows the testing process on a large scale.

Thus, in analyzing the crust of the globe, we find at once two kinds of rocks, the respective work of fire and water: the first poured out from the furnaces within, and cooling, as one may see any mass of metal cool that is poured out from a smelting-furnace today, in solid crystalline masses, without any division into separate layers or leaves; and the latter in successive beds, one over another, the heavier materials below, the lighter above, or sometimes in alternate layers, as special causes may have determined successive deposits of lighter or heavier materials at some given spot.

I could never bring myself to have a poor slave tortured, or put to death, because he roasted ore in a manner which I did not think so good as my own method; nor even because he was not so well convinced as I was of the advantages of our Cornwall smelting-furnace.

Benjamin Jones, a merchant of Philadelphia, invested a portion of his fortune in the purchase of one hundred thousand acres of land in the then unbroken forest of the Pines. The site of the present hamlet of Hanover struck him as admirably adapted for the establishment of a smelting-furnace, and he accordingly projected a settlement on this spot.
