Abstract
AN address to the sixteenth annual convention of the American Mining Congress, Philadelphia, October 20–24, by Mr. C. L. Parsons, of the Division of Mineral Technology, Bureau of Mines, is published in Science of October 31, dealing with the present commercial situation as regards radium and its ores, the available sources of radium in America and elsewhere, the prospecting for, concentration, and costs of mining carno-tite, and the probable future of radium in the treatment of disease. A bulletin is about to be issued by the Bureau of Mines, and an advance statement was issued in April directing attention to the fact that in 1912 nearly three times as much radium in the form of carnotite deposits was produced from Colorado as from all the rest of the world put together, and was exported almost entirely to Europe.
