The American Mining Congress, 841 Munsey bldg., Washington, D. C. J. F. Callbreath, Secretary. The American Mining Congress is a trade association rather than a technical society and as such does not issue scientific papers. Aside from the articles appearing in the monthly Mining Congress Journal, and the Proceedings of the Annual Meetings, only two works have been issued. They are: The standard handbook on mining methods, practice and equipment. $3.

A general method-of-lines numerical approach for modeling gas driven fractures has been developed and tested. The numerical solutions agree very well with known similarity solutions for laminar and turbulent flow. Acceptable accuracy is obtained with a very few numerical grid points and with modest execution times. The model has also been checked against the results of several field tests, in which air was used to drive axisymmetric fractures into permeable tunnel-bed tuff.

University of Nevada's recent Bonanza Days celebration turned out to be the real thing when Kennecott Copper Co, presented the school with $30,000 for new laboratory equipment for the MacKay School of Mines, J. C. Kinnear, Jr., general manager of Kennecott's Nevada Div., handed the check to Stout, university president, Chemical Construction Inter-American Ltd,, signed a contract with Noranda Mines, Ltd. for construction of a sulphur-iron plant in the Niagara Peninsula. Work has been started and it is expected that the plant will be finished by summer 1954.

A system of core logging and computerized entry and retrieval is described which permits accurate and rapid logging of core, cuttings and geophysical records derived from exploration and development bore holes. The system is so constructed that older drilling records can also be utilized. Output consists of conventional computer print out and graphic logs with a variety of scales, symbols and formats. Such logs can be used in constructing rock profiles which are necessary in property assessment and mine development.

The sixty-fifth Congress created a commission on classification and standardization of wages of Government employees consisting of three members of the Senate and three ex-members of the House of Representatives: The Chairman of the National Service Committee has been notified orally by the Vice-chairman that when said Commission reaches the consideration of engineers' salaries in the Government service, request will be made for assistance of Engineering Council. As it is probable that this request will be received prior to the June meeting of Council, it is recommended that action be authorized concerning the appointment of a suitable committee of Council to undertake this work.

This month, Foote Mineral Co. will start to commercially recover tin in the area of Kings Mountain, North Carolina. For 50 years there have been intermittant efforts to recover it but it has finally become economic as a by-product in the mining and concentrating of the associated lithium ore. An unusual deposit of a nonmetallic mineral which is high in sericite, low in quartzite, and similar in physical characteristics to pinite, has been discovered by the Summit Mining Corp. in Adams County, Pa. Work is in progress to determine its suitability for ceramics, fillers, and extenders for insecticides.

First actual production of titanium metal at the newly constructed Henderson, Nev., plant of Titanium Metals Corp. of America occurred in mid-October. Production will be expanded rapidly until the initial goal of 10-tons per day is reached. This will be equivalent to eight times the present world production of titanium metal. W. Eberstady & Co., New York City, has announced plans for construction of a $400 million plant for the manufacture of synthetic liquid fuels from coal in southern Illinois, if the Government will guarantee a minimum price for the gasoline and other products to be produced.

There are many methods of analysis available for compounds similar to those used in solvent extraction processes. However, the majority of these methods are not directly applicable to the determination of solvent extraction reagents, especially in raffinates. The number which are applicable is further reduced if limited to the more simple methods suitable for process control purposes. Commercial extractants are complex mixtures. The complexity is increased by the addition of diluents and modifiers in two-phase systems containing metals. Raffinates from solvent extraction processes contain the more polar components of the extractants and the products of decomposition. Only a limited amount of information is provided by total organic carbon or spectrophotometric analysis. The complexities of the systems require a combination of methods.

A meeting of the New York Local Section of the American Institute of Mining Engineers, in joint session with the American Electrochemical Society, was held at the Engineering Societies Building, 29 West 39th Street, New York City, Nov. 20, 1913. Mr. Lawrence Addicks, Chairman of the American Electrochemical Society, presided at the meeting, in conjunction with Mr. Louis D. Huntoon, Chairman of the New York Local Section of the American Institute of Mining Engineers.
