=French Control.=--French control of tungsten deposits is not large. It includes the production of France and of Tonkin, a part of that from Portugal, and a comparatively small interest in Bolivia. During the war, control in Portugal was attempted by England and France. The prices offered by the English and French were much below the market prices at New York, and the Portuguese government stepped in and raised prices to a point somewhat lower than those of the United States, but 20 per cent. higher than the prices offered by England and France. =Japanese Control.=--Japan has within her own borders a considerable number of tungsten deposits in the southern part of the islands, but all are small. In Korea important deposits have been discovered and actively worked, especially within the last two years. Deposits in Manchuria are said to be controlled by the Japanese; little is known of them, and if they exist they are probably small. Japanese ores have largely come to the United States for several years. As has been said, Japanese firms have erected electric furnaces in which a part of the tungsten ores are reduced, probably the equivalent of 25 to 35 tons per month of concentrates carrying 60 per cent. WO₃. =American Control.=--The United States controls entirely the tungsten deposits within its own borders and Alaska. Americans operating in Mexico have produced 200 to 300 short tons of scheelite concentrates per year, from deposits in the Sahuaripa district, Sonora. Wolframite is said to have been shipped from Sinaloa to the United States, but its real origin is unknown. Contact metamorphic deposits about 60 miles southwest of Nacozari carry 0.7 per cent. WO₃ and 1 to 2 per cent. copper. They are owned by Americans but are not now productive. In Bolivia, Americans own some of the more important tungsten mines. The American firms known to own tungsten properties there are W. R. Grace & Co., local address, La Paz; Stewart, Wilson & Hepburn, Oruro; Easley Inslee, La Paz; and C. Dillon, Oruro. Their total output is estimated to amount to about 1,600 tons, out of a total output of more than 4,000 tons for the country. In southern China, American firms have largely developed the tungsten trade, so that through this source the United States (or rather American capital) controls, unless hindered, a yearly output of perhaps 9,000 short tons of tungsten concentrates. In Siam one or two United States companies have attempted to produce tungsten, but English influence during the war made difficult the shipment of even small lots of ores to this country.
