In the United States deposits of stibnite (antimony sulphide) near 
Gilliam, Ark. ; Battle Mountain, Lovelocks, and Austin, Nev. ; Burke 
and Kingston, Idaho; Tonasket, Okanogan County, Wash.; Granite- 
ville and San Emigdio Canyon, Cal.; Antimony, Utah; Red Bridge, 
Oreg. ; and other places are potentially productive in times of prices 
as high as those now prevailing. 
A greater benefit than the temporary operation of the mines 
would probably accrue to this country from the establishment of 
smelters which would import and smelt Chinese, South American, 
Canadian, and Mexican antimony ores. At present the only regular 
antimony smelting in this country is done by a smelter which is said 
to be a branch of an English smelter. 
ARSENIC. 
The consumption of white arsenic in the United States in 1913 
amounted to about 7,200 tons, valued at $570,000, of which 2,513 
tons, valued at $159,230, was produced in this country as a by 
product from copper and precious-metal smelters, and the remainder 
was imported largely from European countries. For the present 
imports of arsenic will probably be seriously diminished by the 
European war. The American smelters can save much more arsenic 
than they do now, for the cheapness of the product has prevented the 
saving of all that was practicable, and the war would seem to open 
the way for an increase in the American output. 
Works for the exclusive production of arsenic have been erected 
at only two places in the United States—Brinton, Va., and Mineral, 
Wash. It is difficult for such plants to produce arsenic to be sold in 
competition with the by-product of the smelters except in periods 
of high prices, such as may again prevail if the war and its indus 
trial disturbances are long continued. 
PLATINUM. 
The production of platinum from domestic sources in the United 
States in 1913 only amounted to 1,034 fine ounces. Of this, only 483 
ounces was taken from placer mines in California and Oregon. As 
the estimated world’s production in 1913 amounted to 268,339 ounces, 
the United States output amounted to less than one-half of 1 per 
cent. Of the world’s output Russia contributed over 90 per cent 
and Colombia about 6 per cent. In addition to refined metal and 
manufactures of platinum valued at $3,065,489, the refiners in the 
United States recovered 39,154 fine ounces of platinum from im 
ported sands and ore. Much of this was probably used in the manu 
facture of jewelry. It is rather difficult to determine exactly what 
effect the war will have on the Russian mines. The output will 
undoubtedly decrease, but the European consumption of platinum
