PRESENTATION OF MEDALS BY THE AMERICAN INSTITUTE OF MINING AND METALLURGICAL ENGINEERS
ACHIEVEMENT in the mining of cop- per ores and in the smelting and refin- ing of copper was recognized at the annual meeting of the American Insti- tute of Mining and Metallurgical Engi- neers. The William Lawrence Saunders Medal for distinguished achievement in mining was awarded to Francis W. Maclennan, general manager for the Miami Copper Company; and the James Douglas Medal for distinguished achievement in nonferrous metallurgy was awarded to William H. Peirce, president of the Baltimore Copper Smelting & Refining Company and vice- president of the American Smelting & Refining Company.
Mr. Maclennan is a native of Canada and a graduate of McGill University. He has practiced his profession in Can- ada, Peru and the United States. In 1913 he became mine superintendent for the Miami Copper Company, and since 1919 he has served as general manager.
The particular work for which he was cited is the development of a method of mining low-grade copper ore by block caving so efficiently that the over-all cost has been as low as 36 cents per ton of ore. A measure of the success of the operation is the mining of 21 tons of ore per man-shift, a figure never before equalled for underground mining. Previous medalists have been D. W. Brunton, Herbert Hoover, John Hays Hammond and Daniel C. Jackling.
Mr. Peirce, born in Baltimore, was trained as a mechanical engineer. He early entered the copper smelting busi- ness and was remarkably successful in the design and improvement of ma- chines and apparatus for the smelting and refining of copper. He has made notable contributions to these arts, his name being known throughout the in- dustry as the co-inventor of the Smith- Peirce basic converter for the produc- tion of blister copper from matte.
THE PRESIDENT OF THE INSTITUTE AND THE TWO MEDALISTS FRANCIS W. MACLENNAN, WM. H. BASSETT AND WILLIAM H. PEIRCE.
