PROBABLY no man has been of greater service to the Institute and has kept more in the background than Henry Krumb. A Vice-President continuously) for the last eleven years, apparently neither his picture nor a biographical sketch ever have adorned these pages and were he forewarned in the present instance he would order us to "forget it." He is a Columbia School of Mines man, Class of '98. He worked underground at Rossland, B. C. for a time, then for a year and a half a. chief engineer of the famous Camp Bird at Ouray, Colo. For three wars he was examining engineer for the Guggenheims and since 1901 has been an independent consulting engineer with experience throughout the Americas.

JOHN HUNTER NEAD, chief metallurgist of the Inland Steel Co., Chairman of the Iron and Steel Division for 1939, a native of Missouri and graduate of the University of Michigan, first taught chemistry after graduating from college and then decided to follow the field of his college specialization and be a metallurgist. In succession he was associated with the H. H. Franklin Co., Syracuse, N. Y., the Watertown Arsenal, the Racine Steel Castings Co., and the Minneapolis Steel and Machinery Co. During the World War he held a commission as Captain in the Ordnance Department and served both overseas and on the technical staff in Washington. Returning to civilian life, Hunter Nead was research metallurgist and then chief metallurgist of the American Rolling Mill Co. from 1919 until 1931, when he went to his present position with Inland.

NOT a few physical metallurgists started their profession- al careers as chemists or physicists, only to surrender later to the attractions of metallurgy. The present Institute of Metals Chairman varied this more usual sequence in hat his first love was electrical engineering, when as a recent graduate he served on the staff of the General Electric Co., of Schenectady. Soon turning to metallurgy as a more interesting field, he was metallurgist and then chief engineer of the Wads- worth Watch Case Co. from 1920 to 1927. Since 1927 he has been with the International Nickel Co. at the Bayonne, N. J., research laboratories where he is staff adviser.

A full account of the wonderful Arizona meeting will be published in the December Bulletin. For the strenuous, interesting, and altogether happy week, we express our hearty thanks to those marvels of energy and thoughtfulness, the members of the local committees in Texas, New Mexico and Arizona. In this number we publish the discussion resulting from the technical session on "Flotation." Because of the timeliness of the subject, this session's discussion was transcribed first and sent to the contributors, and, thanks to their promptness in revising, we are able to print it in this issue.

PRIMARY blasting at the open pit of the Cananea Consolidated Copper Co. has been developed to meet several conditions peculiar to the operation. Mining at Cananea is not confined to the open pit but is in conjunction with the underground mine which has been in operation for many years. Several old stopes included in the pit area were filled with waste obtained in stripping for the pit. The main haulage tunnel for the underground ore passes directly under one section of the pit and at present is but 180 ft below the pit floor. The pit as originally laid out called for an overall final pit limit slope of 60°. However, the upper 275 ft - a fairly soft oxidized capping, was carried at a 50° slope and the lower benches, which constitute 750 ft in combined height, are being mined to an over-all final slope of 60°.

On Jan. 1, the office of the. National Service Committee was established at 502 McLachlen Building, Washington, D. C. The first work was to review current legislative information; which is being continued and good results are accomplished. Whenever matters of importance appear in the Congressional Record, notice thereof with such documents as are germane are forwarded to the members of the committee for their information and advice. The first formal report of the chairman was on the so-called Smith-Howard bill to secure Federal endowment for the establishment of engineering research. The chairman of the Committee, at the request of the Executive Committee of the Engineering Council, appeared before the Senate Committee on Education and Labor for the purpose of opposing those features of the so-called Kenyon bill which would create a practically permanent commission dominated by the Engineering Corps of the Army over all Federal engineering projects as well as state and municipal projects receiving Federal aid. The greater part of the time has been expended in correspondence and consultation on the matter of the establishment of a Department of Public Works. The results of this work lead to the belief that there is much promise of the establishing of such a department by the 66th Congress Hall members of engineering societies, as well as the societies themselves, will unanimously agree on and support a measure, and in order to secure such unanimous support, it will be advisable to call a conference of engineering societies. .

FAR north of the Arctic Circle is a totally industrial community which until 1945 could not boast a single specimen of the rat family, and where today you will be awarded a bottle of fine cognac for every rat-dead or alive. Amazing but true, the spot is Longyear City, the Norwegian mining town on the arctic island of Spitzbergen. Perhaps you have also heard of the town built on soil that never thaws, where huge blocks of ice must be melted to fill the city's fresh water reservoirs, and where the Far North dictates a way of life all its own. Here, coal is king and men must work hard for their "black gold." Spitzbergen is a rough, tough piece of Norway, made up of a half dozen isolated islands between 74 and 81 degrees north latitude. Covering twice the area of Belgium, they are home to
