It is as if a delicate vessel of Egyptian glass were put to do the work of an iron smelting furnace; and I have to think of all the possible bands and hardening appliances that can be brought into use for the occasion." "I do not understand," I said. "No; I suppose not. That is the worst of it." "But why am I an Egyptian glass?" I asked. "I am not very old."
Previously they had only half realised that they were soberly and seriously making coats, or working machines, or smelting iron, while these jesters were merely cudgelling their brains or consulting back files. The complexity of the thing had disguised the facts.
Dentila is famous for its iron; the flux used for smelting the iron is the ashes of the bark of the Kino tree. These ashes are as white as flour: they are not used in dying blue, and must therefore have something peculiar in them. I tasted them: they did not appear to me to have so much alkali as the mimosa ashes, but had an austere taste. The people told me, if I eat them, I would certainly die.
These two classes of ores are either treated separately, or mixed together in such proportion as is found by experience to be most suitable for the smelting process. On its arrival at the reduction works the ore is taken direct to the stamp mill.
Is there not an element of the picturesque in the struggles of the Western farmer? Can anything be finer in its way than a night view of Pittsburg that "Hell with its lid off," where the cold gleam of electricity vies with the lurid glare of the furnaces and smelting works?
For centuries after, the Turkish nation continued to celebrate the event of their liberation by an annual ceremony, in which a piece of iron was heated in the fire, and a smith's hammer was successively handled by the prince and his nobles. We can only conjecture how the art of smelting iron was discovered.
This is partly inferred from the circumstance of its having been noticed that the Igorots, who occasionally come down from the mountains to barter with the Christians, use certain coarse jars or vessels of copper, evidently made by themselves with the use of a hammer, without any art or regularity; and as the ignorance of these demi-savages is too great for them to possess the notions necessary for the separation of the component parts which enter into the combination of minerals, and much less for the construction of furnaces suitable to the smelting and formation of the moulds, it is concluded they must have found some vein of copper entirely pure, which, without the necessity of any other preparation, they have been able to flatten with the hammer and rendered maleable, so as to convert it into the rough vessels above spoken of.
Far down the road an ore train clattered along on the way to the Sampler, that great middleman institution which is a part of every mining camp, and which, like the creamery station at the cross roads, receives the products of the mines, assays them by its technically correct system of four samples and four assayers to every shipment, and buys them, with its allowances for freight, smelting charges and the innumerable expenditures which must be made before money can become money in reality.
It is very odd that, in a country where mining had been extensively carried on for many years, so simple a process as gently roasting the ore to expel the sulphur previous to smelting it, had never been discovered.
That was why after he had completed his engineering course at Columbia's school of mines and had served an apprenticeship in Colorado and Arizona the Cabell Smelting Company of New York had sent him out to the Land of Moab, as manager of its new-acquired little antimony mine.
