Though most of our own metallurgical works are not so located as to be forced to pay much attention to the removal of noxious vapors, the efforts made abroad possess some interest for American metallurgists. Besides containing sulphurous acid, the gases from the roasting furnaces hold varying quantities of sulphuric acid, and Dr.
And that is the way the farmer's son has learned hog scalding from the time when our ancient fathers got tired of eating bristles and decided to take their pork clean shaven. To-day there are books telling just how many degrees of heat make the water right for scalding hogs, and the metallurgists have written down the chemical formula for puddling iron.
As soon as this stage in the negotiations was reached, it only remained to send a committee of financiers and metallurgists, in company with Dr. Syx, to the Rocky Mountains. They started under the doctor's guidance, completing the last stage of their journey on horseback. "An inspection of the records at Washington," Dr.
It is not France, noble and democratic, which inspires these movements, but a plutocratic situation which has taken the same positions, but on worse grounds, as the German metallurgists before the War. It is the same current against which Lloyd George has several times bitterly protested and for which he has had very bitter words which it is not necessary to recall.
Tested in England, it proved to be pure lead, a metal so rare that some metallurgists have doubted its existence: the finds have been mostly confined to auriferous lands. The African metal is rich.
In some instances, where more than common strength was required, as in the legs of tripods and tables, the bronze was ingeniously cast over an inner structure of iron. This practice was unknown to modern metallurgists until the discovery of the Assyrian specimens, from which it has been successfully imitated.
So has it always been with chemistry, the most cosmopolitan of sciences, the most secret of arts. Quietly and stealthily it crept through the world; the tinker brought it with his solder and his flux; the African tribes who were the first workers in iron passed it on to the great metallurgists who forged Damascan and Toledan steel.
As architects, as designers, as sculptors, as metallurgists, as engravers, as upholsterers, as workers in ivory, as glass-blowers, as embroiderers of dresses, it is evident that they equalled, if they did not exceed, all other Oriental nations. It is the object of the present chapter to give some account of their skill in these various respects.
The wood for the Jewish Temple was roughly cut, and the stones quarried, by Israelite workmen; but all the delicate work, whether in the one material or the other, was performed by the servants of Hiram. The metallurgists of Sidon probably supplied the cherubic figures in the inner sanctuary, as well as the castings for the doors, and the bulk of the sacred vessels.
They make the Australian a savage; incapacitate the negro, who can never invent an alphabet or an arithmetic, and whose theology never passes beyond the stage of sorcery. They cause the Tartars to delight in a diet of milk, and the American Indian to abominate it. They make the dwarfish races of Europe instinctive miners and metallurgists.
