Nicholas Barbon and Sir Dudley North had already attacked the mercantile theory as to the precious metals and the balance of trade; Joseph Massie and Barbon had anticipated his theory of interest.
It was this constant warfare with the Indians and the necessity for hard continuous work, owing to the lack of precious metals in Chile, that no doubt helped to produce in the settlers the strength and hardihood of character that distinguishes the Chileans among South American races.
The precious metals brought in by the tribute were collected in the great, treasure-houses at Susa, Persepolis, Pasargadae and Ecbatana, where gigantic masses of silver and, more Money and especially, of gold, were stored in bullion or partially Coinage.
From the 6th to the 12th century a large number of massive and splendid works in the precious metals were produced at Byzantium or under Byzantine influence, many of which were largely decorated with niello; the silver dome of the baldacchino over the high altar of S.
The Inquisition never had any jurisdiction whatever over the Indians; compulsory labour by the Indians was never legalized except on the missions, and the law was little violated; they were never compelled to work mines; of mining by the Indians for precious metals there is no evidence; nor by the Jesuits (expelled in 1767, after which their missions and other properties were held by the Franciscans), except to a small extent about the presidio of Tubac, although they did some prospecting.
By continuing the treatment of these in the ordinary way of refining, poling and granulating, all the foreign matters other than gold, copper and silver are removed, and, by exposing the granulated metal to a high oxidizing heat for a considerable time the copper may be completely oxidized while the precious metals are unaltered.
He permitted many members of his regiment who had been prospectors in California to prospect the territory, with the result that mines were located at Stockton, Bingham Canyon, Little Cottonwood and elsewhere; but attempts to smelt lead-silver ore near Stockton about 1866 were not successful, and the mining of precious metals did not become an established industry in the Territory until about 1870.
This will create a cascading effect; once energy, for instance, is free, it will make precious metals free.
With increased skill in large castings, and the discovery of the use of cores, by which the fluid bronze was poured into a mere skin-like cavity, hammered or repousse work was only used in the case of small objects in which lightness was desirable, or for the precious metals in order to avoid large expenditure of metal.
A heavier value is shown by the precious metals -- the gold plates from Khorsabad (18) giving 129, and the gold daric coinage (21, 35) of Persia 129.2.
