B. C. MADDEN, JR.2-My comments have no connection with any particular paper; however, since we have talked of stress-corrosion cracking of aircraft parts, cartridge cases? coffee urns, bridge wire, etc., I feel I must mention the apparent significance of this symposium being held in Philadelphia, where perhaps the most famous stress-corrosion crack exists-that of the Liberty Bell. This noon I took advantage of an opportunity to see the Liberty Bell; I commend it to your attention. CHAIRMAN C. S. Cole 3That is true, the illustrations close at hand are the ones we often overlook.

Several alternatives are available for treating lower grade gold ores averaging 0.04 to 0.10 oz per ton. These include heap, vat, and agitation leaching and may involve conventional zinc precipitation or carbon adsorption-electrowinning systems. Each of these processes have their inherent economic and operating advantages and disadvantages and the selection of the optimum method for a given gold ore is solely based on economic evaluation of the applicable processes. In this paper an effort is made to provide engineering feasibility estimates for the above processes under varying operational conditions such as ore grade and price of gold.

Belting worth thousands of dollars can be ruined in a few minutes because of careless maintenance or lack of maintenance. Proper belt conveyor maintenance means having a clean conveyor system at all times. The belt line should be visually inspected during each shift. Equipped with proper maintenance instructions, one belt man can patrol a belt line of 2 to 3 km (1.5 to 2 miles). His duties would be to lubricate drives and idlers (except sealed-for- life type), maintain belt and conveyor frame alignment, detect sticking idlers, and maintain an unobstructed right-of-way.

Grad, the abbreviation for Graduate Resume Accumulation and Distribution, is a computerized information retrieval system operated on behalf of college placement officers around the country by the non- profit College Placement Council, Inc. Grad is free to all engineering candidates (regardless of the number of years of experience) and is a means of getting together college alumni who are seeking new employment and prospective employers. Who is Qualified? Candidates must have at least a bachelor's degree from a four-year college or university, or. in lieu of this, be accredited by a professional institute such as AIME as a full Member.

Among the bills now pending in Congress is one to authorize exploration for and disposition of coal, phosphate, sodium, oil, oil shale, and gas on, public domain. One, to provide protection and government revenue for potash and for zinc ores and products. One to prevent withdrawal of mineral lands from entry and occupancy by law, also to promote, production of quicksilver, tungsten, sulfate, pyrites, and sulfur, and of manganese and manganiferous ores. Three resolutions have been introduced to suspend requirements of annual assessment work on mining claims during year 1919 and one to relieve owners of mining claims mustered into military service.

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

In recent years there has been an increasing effort to attract students into engineering. Obviously, the effort is necessary because young people find the image of the engineer unattractive. Some of the things they find unattractive are real, some are not, and part of the problem is too little knowledge of the field. First, I would like to comment on some of the ideas which appear to be justified. Engineering is a difficult course of study. True, and nothing can or should be done to change this. The education is continually being improved, but it is unlikely to be made easier.

The fourth National Exposition of Chemical Industries will be held in the Grand Central Palace, New York, during the week of Sept. 23, 1918. Dr. Bacon, of the advisory committee, is now head of the Chemical Warfare Section of the National Army, and a member of General Pershing's staff. The coming Exposition will be the largest ever held, and it will be necessary to use four floors of the Grand Central Palace. The exposition is a war-time necessity, and regarding it as such, each exhibitor is planning his exhibit so that it will be of. the greatest benefit to the country.

US 4,190,434 - In the thermal production of magnesium metal, a mixture of calcined dolomite, an iron- silicon-aluminum alloy as a reductant, and residual slag from the production of ferrochromium is smelted to evolve magnesium vapor, which is then condensed. The use of bauxite is lessened or eliminated because of the relatively high alumina content of the residual slag. R. Bonfils, A. Mena, C. Payn, and L. Septier, assigned to Ste.
