At the Pennsylvania Steel Works, Steelton, Pa., a series of trials has been made with oil as fuel in steel-heating and open-hearth steel-furnaces with the following results : First Trial.—Hot 14-inch ingots, six to a charge, were heated in two Siemens' heating furnaces in the blooming mill, the oil being put in first in March, 1888. The oil used had been partly refined, so that the paraffine and some of the naphtha were removed. During a run of six weeks the consumption of oil was about 61/2 gallons per ton of blooms, including the oil required to keep the furnace hot over Sunday.

MANY members of the National Societies died in service overseas during the World War. No memorial to these engineers has been set up but a unique and interesting suggestion has been made. While Edward Dean Adams, Fellow of the American Society of Civil Engineers, and Associate of the Ameri-can Institute of Electrical Engineers, ,vas in Belgium last June as delegate of the National Societies, En-gineering Foundation, and Engineering Societies

Flue-dust, to most blast-furnace operators, means a troublesome by-product, the formation of which should be curtailed, if not prevented entirely. However, with the increasing use of fine ores, larger furnaces, and high-pressure blast, the production of flue-dust is constantly increasing, and amounts annually in the United States to from 3,000,000 to 3,500,000 tons, an exceedingly high tonnage, of which a large part has been discarded as valueless.

Manganese Products, Inc. has developed a chemical process for the recovery of high-grade manganese oxides from low-grade manganese ores. Ammonium sulphate is also produced. Manganese ore is leached with sulphurous-sulphuric acids. The impurities are removed with ammonia, heat, and air. Manganese oxides are produced by addition of more ammonia and air under pressure. Ammonium sulphate is recovered from the remaining solution.

The House Ways and Means Committee recently heard a bitter dispute over whether gasoline with lead is a worse pollutant than gasoline without lead. The lead industry is also squarely in the middle of this dispute for obvious reasons. Lead used in gasoline amounts to 270,000 tpy, or more than 254 of the annual total mined in the U.S. Few industries can face the loss of such a market without wondering how they are to stay in business. The lead industry picked up unexpected support in this dispute, however, when the AFL-CIO stepped up with outright opposition to the President's proposal to tax lead in gasoline.

Curious petroleum, mining and metallurgical engineers together with oceanographers, geologists, geophysicists and those in related disciplines, some 11,500 of them, poured into the Albert Thomas Convention Center in Houston, Tex. to see, and learn. This year's successful Conference, held April 22-24 featured a technical offering of 145 papers presented at 28 sessions. In addition, a total of 500 exhibits were provided by 260 companies.

A $5000 contract to explore for asbestos in Marinette County. Wis., has been entered into between the Government and the Star Mining Co. of Madison, Wis. The Government will contribute 90 pct or $4500 to the cost of the project. The United States presently produces about 8 pct of its asbestos requirements. "Sulphur stockpiles are at a minimum for national security arid must not be further reduced," was the warning given by L. M. Williams, Jr., president of Freeport Sulphur Co. He stated that although the long-range outlook is favorable , current sulphur production cannot meet the demand and as a result the United States faces a crisis in the coming months.

A method to improve the quality of Magmont zinc concentrates to become acceptable feed to an electrolytic zinc refinery is described. The magnesia content of zinc concentrates produced was too high due to particle locking with sphalerite in coarse fractions. Regrinding the concentrates to a very fine particle size and then refloating the sphalerite was chosen to eliminate a sufficient amount of the magnesia to make the concentrates acceptable.

The October meeting of the Mining and Geological Society, Lehigh University, was held in the Eckley B. Coxe Mining Laboratory, and was called to order at 8:15 p. m., by President R. L. McCann. After the reading of the minutes of the previous meeting, a short business session was held, for the purpose of electing a Vice-President to succeed G. S. Borden, who has left college. Nominees for the office were: H. J. Sloman, P. S. Justice, L. Sargeant. Dr. F. F. Hintze, of the Geology Department, was elected a member of the Advisory Committee, which now consists of the President-

This paper describes the use of the magnetometer, under geological direction, in exploration of the Sudbury nickel district. The writer's experience at Falconbridge has led him to the belief that only through detailed work, and by careful correlation of both geological and geophysical results, can geophysical prospecting methods be applied successfully to mining exploration problems. It is hoped that the basic technique described in the paper will be found to have general application.

The operation of a mineral processing plant with a complex flowsheet is represented by a mathematical operator. Such a representation permits a quantitative evaluation and monitoring of the separation processes in different sections of a processing plant, and gives an overall separation efficiency of the plant.

Objective stockpile goals have been met for antimony, bismuth, fluorspar, and iridium, while those for bauxite, cadmium, copper, lead, zinc, manganese, mercury, platinum, tin, and vanadium have not, according to a report by the Munitions Board. Total materials under inventory and contract represent about 78 pct of entire stockpile goals, the report stated. Frobisher, Ltd., of Canada has been given permission to survey power possibilities in certain lake and river basins in the Yukon believed to have a potential of 5 million he. Canadian Resources Minister, Robert Winters, also announced that his Government has rejected a bid by Aluminum Co. of America concerning use of Canadian waters to power a proposed Alaska aluminum project. Alcoa is reported hopeful of resuming negotiations.
