In response to suggestions of members of the Founder Societies, the following telegram was sent, Oct. 29, to the President and each member of his cabinet. "Engineering Council respectfully recommends appointing on new Industrial Conference two or more engineers familiar with industrial problems. Council represents five national societies of professional engineers having forty-one thousand members. Washington office in McLachlen Building."

AT the Morenci branch of the Phelps Dodge Corporation, of which Frank Ayer is manager, several new types of machines that have been developed by Charles Mitchell, shop foreman in the drill steel shop, invite comment for their time and labor-saving qualities. Foremost of these is an adjustable gage-block and gaging device for attachment to drill-sharpening machines, developed and patent applied for by Mr. Mitchell. It replaces the blocks on the standard Ingersoll-Leyner drill steel sharpener No. 5. Features of the device are gage blocks with a flat surface which can readily be removed when worn and planed in any flat planer; blocks that can be adjusted with a templet to give a far more accurate gage than was formerly possible; and a center stop that is adjustable and can be accurately set to center any standard size drill steel.

The oil and gas industries in Montana continued through the year of 1937 with but little change. No new fields were discovered, and production of old fields did not vary greatly. No outstanding wildcat wells were drilled. Perhaps most notable were extensions in the western part of the Kevin-Sunburst field. Acid treatment of wells in the Kevin and Pondera fields continued with gratifying results.

SEAMSYS and CSD/SMP are sets of computer programs that assist geologists and mine engineers in modeling and evaluating coal properties. The systems are tailored for treatment of waste and coal quality data, including metallurgical coal product capabilities. The gridded SEAMSYS model honors all drillhole data and incorporates user- defined mining parameters, losses and dilutions, and operational constraints. A variety of reserve reports and graphic displays are available from the model. Preliminary mine planning is accomplished through automatic cut generation and production targeting. CSD/SMP refines the preliminary plans to help anticipate the consequences of various mine schedules and evaluate equipment capacity requirements.

A method is proposed for computing (a possible solution of) the ground reaction curve, for use in tunnel support analysis, in cases where the initial stress field is not hydrostatic. Rock around a circular tunnel is assumed to behave as an elasto-plastic material with a Mohr-Coulomb yield envelope.
