Now, however, aluminum is universally available and with the expiration of certain patents, the material has sold as low as 25 cents a pound. Electrolytic methods serve also for the refining of nickel and for the production of lead, and as in other fields of metallurgy, these processes are attracting the attention of chemists and of engineers.

Metallurgy and agriculture were the two arts whose invention produced this great revolution. With the poet, it is gold and silver, but with the philosopher it is iron and corn, which have civilized men, and ruined mankind.

Coal is the key to metallurgy and oil to transit. When they are done we shall either have built up such a fabric of apparatus, knowledge and social organization that we shall be able to manage without them or we shall have travelled a long way down the slopes of waste towards extinction.... To-day, in getting, in distribution, in use we waste enormously....As we sit here all the world is wasting fuel fantastically."

The latter was an apt scholar, and made great progress. By chance the work of Isaac Hollandus fell into his hands, and from that time he became smitten with the mania of the philosopher's stone. All his thoughts henceforth were devoted to metallurgy; and he travelled into Sweden that he might visit the mines of that country, and examine the ores while they yet lay in the bowels of the earth.

There he continued to flourish for six years more, making steel and practising benevolence; for, like the Darbys and Reynoldses of Coalbrookdale, he was a worthy and highly respected member of the Society of Friends. He was well versed in the science of his day, and skilled in chemistry, which doubtless proved of great advantage to him in pursuing his experiments in metallurgy.

Le Play the French Professor of Metallurgy, in his Memoire of 1846, still speaks of the cast-steel bearing the mark of "Huntsman and Marshall" as the best that is made, and he adds, "the buyer of this article, who pays a higher price for it than for other sorts, is not acting merely in the blind spirit of routine, but pays a logical and well-deserved homage to all the material and moral qualities of which the true Huntsman mark has been the guarantee for a century."

There were visitors at Myrtle Forge, Abner Forsythe, who owned the other half of Shadrach, his son David, newly back from England and the study of metallurgy, and a Mr. Winscombe, come out to the Provinces in connection with the Maryland boundary dispute, accompanied by his wife. All this Howat Penny regarded with profound distaste; necessary social and conversational forms repelled him.

This is from that author's work entitled, "Electro Metallurgy," American edition: "The cyanide of potassium, so often alluded to while treating of the metallo-cyanides, may be formed in several ways. It may be obtained by heating to a dull redness the yellow ferrocyanate of potash, in a covered vessel, filtering and rapidly evaporating it.

The usual material of the Assyrian ornamental metallurgy is bronze, composed of one part of tin to ten of copper which are exactly the proportions considered to be best by the Greeks and Romans, and still in ordinary use at the present day.

Hence we may reasonably infer that the art of bronze-making was developed in Asia by a copper-using people, and that when metallurgy was first introduced into Europe the method of mixing the copper with tin had already been perfected.
