30 OUR MINERAL RESERVES. for jewelry and other purposes will be negligible. Prices for the metal were high during the last two years, and any large increase in values will probably result in a lessened consumption. The supply of crude metal available from sources other than Russia will not probably exceed 20,000 troy ounces. The high prices in 1913 did not result in any increase of the output from domestic mines, and it is not likely that the yield of platinum from such mines in 1914 will exceed 2,000 ounces. The sources of the domestic output have been limited to placer mines in California and Oregon and the Rambler mine in Wyoming and to the recovery from the refining of foreign and domestic bullion, scrap, sweepings, etc. It is reported that ore which carries considerable platinum is now being mined in Nevada. Although it appears that the supply of platinum will be only about 25 per cent of that formerly available, it will be sufficient for neces sary mechanical purposes if it is not diverted to mere purposes of personal adornment. RADIUM. The European war has, for the present at least, totally closed the European market to American radium ores. As is well known, the uranium ores of Colorado and Utah are sold exclusively for their radium content, so little use being known for the uranium that the ores can not be sold for their content of that element. The closure of the European market leaves the miners without a buyer; so that while the war lasts, and probably for some time afterward, the market will be restricted and without the benefit of competition. As already pointed out by Secretary Lane, had the bills introduced in Congress been passed, the United States Government would prob ably have been in the market as a buyer, and the miner might now have a chance to sell his ore. MISCELLANEOUS MINERALS AND MINERAL PRODUCTS. CEMENT. The United States imports relatively little hydraulic cement, only 34,630 barrels having been imported in 1913, whereas the domestic production in that year was nearly 93,000,000 barrels. There is little or no need to import any cement, for all parts of the country are now fairly well supplied with mills for the manufacture of Portland cement, and the supply of raw materials is practically inexhaustible. A significant feature of the cement industry, however, is the fact that, though only about 80 per cent of the normal cement-producing capacity of the country is employed at the maximum, there is often an overproduction ; yet the exports of hydraulic cement have scarcely exceeded 4,200,000 barrels in any year, this amount being only about
