One of these finds. known as the Tungsten Reef Mines. promises to be one of the largest producing properties in this country. and it is probable that in the future both Nevada and Arizona will outrank California and Colorado as prodiicing States. * The Nevada properties have been equipped with extensive mining and concentrating plants. but these were only in operation about two months before the slump in the late fall of 1918. The Arizona property had been provided with a large concentrating plant. whichwas delivered on the ground. but has not been erected on account of market conditions for the material. Production in the United States during the year 1918 continued at a high level until the signing of the armistice in November of that year.- when a decided reaction set in. caused by cessation of the demand and by heavy importations of foreign ores. chiefly ore from China. particularly that which did not have to be mined but could be picked -up from the ground by. cheap coolie labor. Prior to the Wvar Germany was In absolute control of the tungsten refining Industries. as very little was being refined in the United States or England. American ores were shipped to Germany. reduced there. and returned to us in the forms of ferrotungsten and tungsten powder.
