ENGINEERING department problems of unravel- ling filing systems of reference data, detail drawings, magazine tear sheets, technical records, manufacturers' catalogs-and coordinating them with the information classification systems employed by the company library and other information services -are being solved in many cases by adopting a basic classification system such as that used by Sweet's Catalog Service and applying its classification and indexing methods to file or bookshelf. By this procedure the engineering department does away with the confusion, duplication, and conflict that exist between personal, department, and company library files. It establishes a pattern for regulating and distributing the potential information that piles up daily in the engineering department basket marked "Incoming."

EUGENE McAULIFFE, * St. Louis, Mo.-The method employed by the Engineer's Committee in arriving at a proper selling price for coal and coke represents hard painstaking effort based on a thoroughly scientific foundation; and the United States Fuel Administration can well point with pride to the work of this committee. The results so obtained placed

THE etch-pit technique for revealing dislocations in bulk samples allows one to determine dislocation densities and to study their behavior under various mechanical and thermal treatments. We have developed a chemical polish-etch for the development of etch pits on the (1100) plane of Cd which appear to

Nippissing Mines Co., Ltd., a Ventures subsidiary, has bought into the, Vermont Copper Co. Inc. which operates a copper mine in Vermont producing 700 tons daily. The Vermont Mining Co. has been in operation since 1943 under the present management. When present owners wanted to convert their holdings to cash, the Ventures people saw possibilities in the area which, has been little explored but has a sizable production record. Final approval of the Anaconda-Harvey project for a 72,000 ton aluminum reduction plant at Kalispell, Mont., has been announced by Defense Production Administration. After considerable discussion in the past few weeks regarding Anaconda's entrance into the aluminum field, the approval stated "clearly the best arrangement."

The writers are to be congratulated for their excellent paper on a subject dear to the hearts of manufacturers of cold rolled sheets. Gary Works produces rimmed steel ingots up to 53,000 pounds teemed 91 inches high in 31 x 84 inch molds. By the writers' definition, this puts us in the small mold category, and a comparison of their adopted melt shop practice with our established rimmed steel practice discloses not a dime's worth of difference between us. This should give comfort to the writers for we at Gary have- never encountered the frequency of white line rejections as described in their paper.

This paper is the first in a series which will describe geology, mining methods, and production costs of some of Turkey's more important minerals. In this paper the economically significant minerals-chromite, meerschaum, and magnesite-of the Tastepe district are described. The cost data presented are believed by the author to be the first made public on Turkish chromite mining.

This paper assesses some of the critical factors that must be considered and addressed in the implementation of small computer systems for technical applications within a coal company. Aspects of hardware selection that are somewhat specific to the coal industry are discussed, and a table of potential areas of application is presented. The dilemma of internal software development is presented and a software development program based on a users group approach is outlined and discussed in detail.

Coal Transport Via Pipe Line Claimed Feasible Moving coal via pipe line is a project proposed by the U. S. Bureau of Mines. A pipe line 100 miles long capable of transporting 5000 tons of coal a day with water could be built for about $10 million. The cost of moving the coal 100 miles would be between $1.28 and $2.01 a ton.

Henry D. Hibbard, Plainfield, N J. (communication to the Secretary*):—This very interesting history is a valuable addition to our knowledge of the basic process and its introduction to this country. In addition to the attempts noted in the paper which were made here to establish the basic Bessemer process, and the experiment with the Siemens-Martin process at the Otis works, there were others made with the latter-named process at about the same date, all of which failed or, at least, were discontinued. The first attempt which survived was that of Carnegie,

Recognizing the fact that the problems of the committee named by the Board to prepare the "official ticket" for officers and Directors of the Institute are various and difficult; and desiring to assist this committee by setting forth some of the principles that should guide the committee and some of the qualifications that should be required of candidates, the following instructions are formulated and the Secretary is directed to publish them in MINING AND METALLURGY concurrently with the publication of the names of each newly appointed Nominating Committee and to send a copy to each member of the Committee.

SOME time ago, a firm engaged largely in the manufacture of copper sulphate, applied to me for information as to the practicability of obtaining the copper from their mother liquors by means of electricity ; having reference, more especially, to obtaining the electric current from some magneto-electric or dynamo-electric machine. The mother liquors were the result of several solutions of commercial scrap copper, containing impurities, the quantity of which
