expected to be near the end of their gold production, F.Lynwaod Garrison, Philadelphia mining- engineer, warned the American Institute of Mining and Metallurgical Engineers meeting recently in New Yark. The future production of the Witwatersrand's gold mines, said Mr. Gamsan, depends on the possibility of mining and milling profitably the large tonnage of relatively low-grade ores known t o exist in that area. The director of the U. S. Mint, Robert J. Grant, presented figures showing that the production of new gold is mounting throughout the world following the decline that set in after the World War. Since the discovery of America, 40,000 tons of gold have heen produced throughout the world, Mr. Grant estimates. In the ~roductionof new a d d . he said South Africa not only stands first just now hut in rrrrnt yrars hxs iwen f ~ inr the lead of allothcr regions. In tllr futurrrconumic development of the world, thcrcfort. the South African supply of the standard metal is of paramount inlportnncr I h r i n ~the nrxt l r s ywrs, African productton r i l l bemmr even more important de~pitt-the critical technical prohlcms at prescnt facing the gold industry of that continent. Bankers joined with the engineers in discussing whether enough gold is being mined and whether the present business depression is related t o the gold supply. The money users of the nation plan t o join forces with the engineers in conserving t h e gold supply by devising methods of using less gold in their monetary dealings, George E. Roberts, vice-president of the National City Bank, indicated in his discussion.Science S r n . 6 ~
