Acid treatment of wells in the Kevin and Pondera fields continued with gratifying results.

(written discussion*).-As a sup-plement to the information given by Mr. Bash, a diagram is submitted showing the results of a somewhat similar experiment carried out at the ordnance plant of the Standard Steel Works Co. In this case the ingot to be heated was a nickel-steel octagon ingot, weighing 14,700 lb. (6667 kg.). This ingot was to be forged into two 255-mm. howitzer jackets. A hole was bored half way of the length of the ingot, extending into the longitudinal axis, and a base-metal thermocouple inserted in this hole.

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.

MINE hoist ropes have hitherto been selected by successive approximation, a process both tedious and inexact. The proposed expression is a readily solved synthesis of existing data and the following standard equation:1 [ ] For convenience, a glossary of all terms appears on page 564. Since rope weight (Wr) and bending load (B) are functions of unit rope weight (Wo), which in turn is a function of rope strength (T), W, and B can be expressed in terms of T. Wr as a Function of T: A study of the curve in Fig. 1, unit rope weight vs strength, yields Eq. 2:

Partition (Tromp) curves, as used in diagnosing problems in coal cleaning equipment, are discussed and classified using five arbitrarily chosen types to represent, on a scale from one to five, system performance. Causes of unsatisfactory Tromp curves for various cleaning units, ranging from operational inadequacies to problems best corrected by the equipment builder, are analyzed.
