F. N. FLYNN, Clifton, Ariz.-I would like to ask Mr. Mathewson what percentage of his leaching liquor is wasted at this time? It has a bearing on the question in connection with the New Cornelia, and I think it is a very important question. E. P. MATHEWSON, Anaconda, Mont.-I am not sure what the percentage is now, but we don't discard the strong liquors. Something like 25 per cent. of the wash water taken out each day is sent over a special set of scrap iron tanks, and the copper recovered there. We had a little trouble at first. We did not proceed to use the sponge iron for the reason that the plant we originally contemplated was abandoned for flotation. Our original idea was to use a leaching process on all the tailings of the mill, but we found it would take a great deal of time to build a plant; and the cost of operating the plant we estimated to be about the same and the recovery the same. It was a question of time with us, and we decided to adopt flotation. That changed our plans. We now have the leaching plant, treating the tailings of the old dump, and the flotation applied to the current tailings. The sponge iron was figured for the large plant. We can get all the scrap iron necessary for the small plant-plenty from the scrap produced in the main plant of the smelter.

MANY years ago when the writer chaperoned a group of student officers from Wright Field on their re- quired inspection trip through the Mid- dletown plant of American Rolling Mil1 Co., Leo Reinartz was our guide. After the party had watched continuous strip being rolled and was ready to move on we ventured a remark-to emphasize the difference between Armco iron and automobile fender stock-that this strip was ordinary steel. The remark was overheard by our guide and the effect was instantaneous; in a rather re- proachful tone Leo said: "Gentlemen, your teacher has been in this plant many times, and he should know by now that we, in this company, never make ordinary steel-all of our prod- ucts are the highest possible quality."

A NOTED Prospector Passes-Stories of the grizzled old prospector that discovered what turned out to be a famous and highly profitable mine, only to die in poverty through the shenanigans of "the Interests," are legion. It is pleasant, therefore, to be able to report that the discoverer of one of Canada's most famous mines was more fortunate.

The American Institute of Mining Engineers, the American Society of Civil Engineers, the American Society of Mechanical Engineers, and the American Institute of Electrical Engineers have established the . Engineering Societies Employment Bureau under the management of their Secretaries. One of the purposes of the Bureau is to keep in touch with all engineering firms with a view to supplying them with desirable men. Plans are under way to assist in placing men who are retiring from the government service. The Bureau is not intended to be exclusively for the benefit of unemployed members, of the Founder Societies; non-members who are introduced properly will be registered. Information, registration forms, etc., may be obtained from the office of the Bureau, Engineering Societies Building, 29 West 39 Street, New York, Room 903.
