and Nevada, which in 1920 produced over half of the copper mined in the United States, 13 are now operating, compared with two year ago. In May, 1922, the output of nine of the 13 mines was 24,SS3,OO0 pounds, compared with 22,764OOO pounds produced in April, 1922, and 5,952.- 900 pounds in May, 1921. Production of copper in the United States dur ing May was reported to be 68 per cent of normal, compared with 59 per cent in April, 46 per cent in six months period, Ju1y-December, 1921. The trend of copper prices continued upward during June, and at present quotations (13.5O to IA cents per pound) mining of this me tai is profitable for the mines with l relatively low production costs.3 The average price per pound of electroly- tic copper in New York was 1889. cents in June, compared with aver age prices of 1896 cents in May, 12.S2 cents in April, 12.94 cents in; June, 1921, and 14.11 cents during the five years, 1909-1913 Increased activity was noted in gold, silver, and lead mining in the district during June, 1922, as com pared with May, 1922.
