Is my paper on Mexican weights and measures, presented at the Bethlehem meeting, I gave a formula for the reduction of Mexican ounces per carga to American ounces per ton, which may prove misleading. I wish therefore to substitute the following rule: To reduce Mexican ounces per carga of 300 Mexican pounds to Troy ounces per ton of 2000 pounds avoirdupois, multiply the number of ounces per carga by 6.078. Or, to reduce Troy ounces per ton of 2000 pounds avoirdupois to Mexican ounces per carga of 300 Mexican pounds, multiply the number of Troy ounces per ton by 0.165.

The Mining and Metallurgical Club of the University of Toronto held a very successful meeting at the Engineers' Club on Jan. 29, 1917. Interesting papers on the Arizona Mining Districts and on the Creighton Mine at Sudbury were read. Several members of the freshman class who have changed from other branches of engineering to mining have been taken into the Club, so that we are now booming. We are also making an attempt to have more of our members apply for junior membership in the Institute, and hope to report favorably along these lines in the near future. C. A. RICHARDSON, Secretary.

PROFESSOR CECIL H. DESCH of Sheffield Univer-sity is to give the sixth annual Institute of Metals lecture in connection with the A. I. M. E. meeting in February. Professor Desch is well known to metallur-gists in this country not only from his books on metal-lography, intermetallic compounds, the physicist in metallurgy, and the chemistry and testing of cement, but also by his many published papers in the technical journals. Professor Desch is the third distinguished foreigner to lecture before the. Institute of Metals under its pro-gram which calls for an annual lecture by a distin-

HE Hose Memorial Lecture, in memory of Henry Marion Howe, Past President of the Institute, was authorized in April, 1923, as an annual address to be delivered by invitation under the auspices of the Institute by an individual of recognized and outstanding attainment in the science and practice of iron and steel metallurgy or metallography, chosen by the Board of Directors upon recommendation of the Iron and Steel Division. The following were the Howe lectures and lecturers for the years indicated: 1924 What is Steel? By Albert Sauveur. 1925 Austenite and Austenitic Steels. By John A. Mathews.

MEMBERS of the Research Committee lunched to-gether on Monday and discussed the work and plans of the Committee. Some re-assignment of duties was made and a request put in for another member specializing in lead and zinc. By request, Director Flinn of the Engineering Foundation presented the problem of the proposed investigation of iron alloys. It was decided to call together a special committee in May to determine on recommendations. A. C. Fieldner discussed coal research and Chairman Manning was authorized to ascertain by letter ballot the opinions, on certain phases of this, of all members of the Committee.

Data about shipments in this county are more plentiful than in most others. Canal records, although not complete, are available for 1837-1840, 1856-1857, 1859 and 1864. The census figures, and those of the reports of the Secretary of Internal Affairs, are very evidently too .low. Local consumption within the county has always been large, mainly due to the Cambria Iron Company, and other manufacturing plants, in Johnstown; here a large coke supply was made from coal directly from the mines, neither coal or coke being handled by any outside transportation agency. All available data is shown in Table 35.

J. Pearson (British Iron and Steel Research Association, London, England)—Dr. Wagner has referred to the work of Richardson and Dancy and Gellner and Richardson on the reduction at 900°C of wustite films on iron. He has assumed that iron ions and electrons migrate backwards to the iron-wustite interface and that the reduced iron grows on the metal substrate. This would be a possible explanation of the results of these workers were it not for the fact that, as stated by Gellner and Richardson but not stressed, this growth in the center of the specimen can occur even

The University of Idaho Mining Society held a meeting on Oct. 23, and elected the following officers: President, Sam Bloom; Vice-President, Lloyd McDougall; Secty Treas, Jess W. Wade. Regular meetings are held on the first and third .Tuesdays of each month, for informal lectures and reports on technical subjects. The Mining Club of the University of Wisconsin has held four recent meetings On Oct. 17, sixteen new members were inducted, and a committee was appointed to buy a Liberty Bond. The second meeting, Oct. 31, was devoted to general entertainment, at the home of Professor McCaffery.

The material described below was made at Furnace No. 2, Longdale, Va., Oct. 28, 1907, during a sudden derangement of working, in the course of which the furnace became entirely bridged over and for some time no solid material whatever descended into the hearth. This caused the hearth to become so completely emptied that, at the tuyere-level, a pricker put in at one tuyere could be seen by looking in at the opposite one. The tap-hole was opened and the iron got out with some difficulty. It ran sluggishly, throwing many sparks, but was not

To the question, "Do the Pennsylvania anthracites contain phosphorus ?" asked at the last meeting of the Institute during the discussion on the metallurgical value of Western lignites, I can now give a definite answer. Through the kindness of a gentleman connected with the Philadelphia and Reading Railroad, and another connected with one of the principal ironworks on the Lehigh, there was sent to the Iron-masters' Laboratory a number of samples of the coals now largely shipped from the Schuylkill and Lehigh regions. Seventeen of these I examined for their contents of ash and phosphorus, and obtained results as follows

WHEN the atomic age broke suddenly upon the world in 1945 with all its terrible implications, predictions concerning the future of atomic energy were as numerous as columnists and often inflated. Today, some seven years since the explosion and probably ten since the Government took over development of nuclear energy, the impact on our way of living has been largely political (except of course for the thousands of people who have become employed in the AEC). Considering the world situation, weapons have come first naturally. But credible progress in the plow-share uses of nuclear energy-medicine, agriculture, power-can also be noted.

The most notable development in oil and gas operations in Montana during 1938 were extensions to the Kevin-Sunburst and Cut Bank fields. No new fields were discovered, although about 20 widely scattered wildcat wells were operated. Within or adjacent to proved fields about 100 wells were drilled, resulting in 81 oil wells and 14 gas wells. In general, production activities were below those of 1937, largely because of market conditions. Markets for crude were improved late in the year by construction of refinerirs at Pocatello, Idaho, Spokane, Washington and Cut Bank; and also by price concessions. However, demand was much

SPONGE iron as produced at Anaconda is a fine, -35 mesh, impure product, about 50 pct metallic iron, obtained from the reduction of iron calcine at a temperature of 1850°F by use of coke resulting from slack coal. The metallic iron particles are bulky and spongey and precipitate copper readily and rapidly from a copper sulphate solution. Investigation of the treatment of Greater Butte Project, Kelley, ore at Anaconda early showed the desirability of using sponge iron as a precipitant for the copper in solution resulting from desliming of the ore in a dilute sulphuric acid solution.

(Read at the Wilkes-Barre Meeting, May, 1877.) IN vol. 33 of the Proceedings of the Institution of Civil Engineers, London (part 2, for 1870-71), may be found a statement of the cost of two blast furnaces, together with a somewhat detailed description. The attempt will be made in this note to restate these items of cost, so that the information may be rendered perhaps more accessible to our members than in its present place of record, and also in order that the items may be more intelligibly compared among themselves, or with similar items in other cases.
