The application of the doctrine of the existence of seed in metals led to the performance of many experiments, and, hence, to the accumulation of a considerable body of facts established by experimental inquiries.
This is set forth by a double metaphor: one taken from the refiner’s fire, which purifieth metals from the dross; the other, from the fuller’s soap; others read the fuller’s grass, or the fuller’s herb. Some have thought it so hard to determine, that they have kept into the translation the very Hebrew word borith.
All the absolute requirements of social life and of commerce among the ancient Greeks and Romans were satisfied by the use of the precious metals as money, though the want of new facilities and new instruments of commercial exchange must have been constantly experienced.
During early centuries in the history of western civilization adventurers and prospectors concentrated on the precious metals. The voyagers and discoverers who sailed fifteenth century seas were seeking supplies of gold, silver and precious stones that could be cut and converted into the highly prized jewels adorning the crowns and scepters of the mighty.
But his most devoted worshipers thought that the god's noble, benevolent, grave countenance had a wrathful look; for, though nothing had been altered in this, the finest pillared hall in the world; though the beautiful pictures in relief on the walls and ceiling, the statues and altars of marble, bronze, and precious metals between the columns, and the costly mosaic-work of many colors which decked the floor in regular patterns, were the same as of yore, this splendid pavement was trodden to-day by thousands of feet which had no concern with the service of the god.
The engraving given herewith shows a general view of the "Demon" cold saw, designed for cutting iron, mild steel, or other metals of fairly large sections, that is, up square or round, and any rectangular section up to 8 in. by 4 in. The maker, Mr. R.G. Fiege, of London, claims for this appliance that it is a cold iron saw, at once powerful, simple and effective.
Recommendations will be made from time to time for the adoption of: A uniform and consistent water resources policy; A revised public lands policy; and A sound program for safeguarding the domestic production of critical and strategic metals and minerals.
"Oh!" ejaculated my father in a disappointed tone; "but are you sure?" "Sure, sir? Yes. I'm not clever, and I'm better at gunshot wounds and amputations than at medical practice, but I do know a bit about metals and mining. Why, didn't we touch at Banca in '44 and see the tin mining there?" "Yes," said my father; "but I took no interest in it then." "Well, I did, my lad. Tin? No.
The first laws developed for cutting metals were crude, and contained only a partial knowledge of the truth, yet this imperfect knowledge was vastly better than the utter lack of exact information or the very imperfect rule of thumb which existed before, and it enabled the workmen, with the help of the management, to do far quicker and better work.
Nevertheless, their influence led the way in discountenancing the art, and it has so entirely died out that there is probably not a completely tattooed Maori head on living shoulders to-day. Cook had found the Maoris still in the Stone Age. They were far too intelligent to stay there a day after the use of metals had been demonstrated to them.
