Rare earth element (REE) analyses of cumulus plagioclase from the PGE ore zone of the Stillwater Complex indicate that pressure fluctuations in the magma chamber acting on a single magma cannot be responsible for features such as the reappearance of Mg-rich olivine on the liquidus. The data are more consistent with a model involving multiple injection and mixing of geochemically distinct magmas. The PGE-bearing sulfides of the J-M Reef are associated with such a reappearance of olivine, indicating that the unusual location of the ore zone may be related to the addition of new magma, compositionally distinct from magmas that produced cumulates in the Ultra- mafic zone of the complex.

HAPPILY, a large group of the non-ferrous fraternity have long valued a personal association with the new Chairman of the Institute of Metals Division. Many others who will meet him, either officially or unofficially this year, will find themselves sharing the enthusiasm with which he has been welcomed to his new office. Albert A. Smith, Jr., was born at Butler, N. J., on Dec. 28, 1904, and moved to New Haven in time to initiate his preparation for Yale University on the home grounds. After receiving a B.S. degree cum laude in 1926, he stayed on for graduate work at the Hammond Laboratory under C. H. Mathewson, and was awarded an M.S. degree in 1928.

AN ENGINEER with as varied geographical experience as H. J. Brown does not often specialize on one particular thing all of his professional life. For forty years he has been engaged in gypsum mining, manufacturing, plant design, construction, and operation. Not only is it his work, but he says it is his hobby as well, though membership in three yacht clubs might belie that statement. New England's new representative on the A.I.M.E. Directorate, who was born in New York, Dec. 20, 1879, went to the Lawrence Scientific School at Harvard at the turn of the century. He tried journalism for a year, with the Boston News Bureau and associated financial

THE two illustrations below, furnished through the courtesy of J. P. Messervey, Deputy Inspector of Mines, Department of Public Works and Mines, Province of Nova Scotia, show a fourth-level stope in the salt mine at Malagash, N. S. Fig. I was taken when the stope was begun, and Fig. 2 shows how it looked two months later, the photographs being taken from the came point. This stope is at a depth of about 300 ft. and is on the MacKay seam, which is the central band of white salt running through the Malagarh deposit. As run be seen. the vein is vertical. and varies from a foot to 50 ft. in thickness. The

At a meeting of the Board of Directors, held Jan. 21, 1916, the following resolution was adopted: Resolved, that this Board has learned with indignation and sorrow of the unprovoked and brutal murder of 18 American citizens on January 10, in the State of Chihuahua, Mexico, and laments especially the death of Messrs. C. R. Watson, C. A. Pringle, H. C. Hase, and W. J. Wallace, who were members of the American Institute of Mining Engineers. As these men and their companies were engaged, in the lawful prosecution of their work, we trust that nothing will be allowed to prevent or delay appropriate action by our Government concerning the outrage by which they lost their lives;

IT SEEMS particularly appropriate that the Institute's Regional Meeting should be held in Minnesota this year. Whether we like it or not, we cannot help looking at things now in the light of the World War and the all-out effort we, as a nation, are making to defend our resources, our institutions, and our way of life. The ability to do this lies in large measure in the ability to forge weapons of defense-the machines of war. The basic ingredients of any defense system, or war machine, are the raw materials of industry-iron ore, providing steel for guns, shells, tanks, and warships; coal for stoking the nation's furnaces; oil to furnish power for war planes, ships, trucks, and mechanized weapons; and all the other materials that play a vital role in the operation of modern armies and navies. The tremendous requirements of full-scale defense programs are indicated by the large number of commodities that are now under priorities because the supply is not sufficient to meet both defense needs and all normal civilian consumption. But out of all these items two are of paramount importance-steel and petroleum. In this age no nation can hope to main¬tain a position as a first-class power in the world without a highly developed industry, particularly the heavy industries based on steel, and without access to the necessary resources for those industries. In 1918, 70 per cent of the iron and steel production of the United States was required for defense purposes. In 1940, 15 per cent of our iron and steel production was consumed for defense purposes, and with the acceleration of the defense program, it appears that the proportion of steel output required for defense purposes will reach 40
