Wildcat drilling operations in Montana during 1933 did not yield any discoveries of oil or gas that were of major importance. There was comparatively little drilling in the older proven fields, as most of the interest was centered in the Cut Bank field, where 44 wells were completed. The total number of wells completed in the state during the year was 79, of which 62 were productive of either oil or gas.

OBSERVATIONS were made over a period of seventeen months to ascertain the economic value of a four-cycle Miller engine direct-connected to a Watts compressor, to determine whether this type of engine could compete suc-cessfully against the old type of two-cycle engine in general use. The accompanying tables show the data obtained. The first, over a period of seventeen months, compares the operating cost per hour and cost per horsepower-hour with

274. The PHYSICAL CHARACTERS of minerals fall under the following heads : I. Characters depending upon Cohesion and Elasticity - viz., cleavage, fracture, tenacity, hardness, elasticity, etc. 11. Specijic Gravity, or the Density compared with that of water. 111. Characters depending upon Light - viz., color, luster, degree of trans- parency, special optical properties, etc. IV. Characters depending upon Heat -viz., heat-conductivity, change of form and of optical characters with change of temperature, fusibility, etc. V. Characters depending upon Electricity and Magnetism. VI. Characters depending upon the action of the senses-viz., taste, odor, feel.

It has been suggested that it would be a desirable feature in connection with the Chicago meeting of the, Institute in September to arrange for a return trip for the fuel men through the coal fields of Illinois, Ohio and Pennsylvania, stopping at various points and possibly touching also Kentucky. Perhaps the petroleum men would be interested in a similar trip and might join them stopping off at different points to visit these oil fields. If the members who would-be interested in such a trip will advise the Secretary before the first of June, indicating their desired stopping points, steps will be taken to perfect arrangements accordingly.

IN several alloys of iron, copper, and lithium as well as in some pure metals, martensite formed on cooling reverts to the parent phase upon heating to a temperature below the equilibrium temperature at which the parent phase becomes stable.' These martensitic transformations, therefore, are thermally reversible, although appreciable hysteresis may be involved. The martensitic reaction has long been

In his paper on "The Accumulation of Amalgam on Copper Plates,"f Mr. R. T. Baylies records the fact that at the Drumlummon mill, at Marysville, Montana, a series of tests proved that silver, instead of showing a strong affinity with the amalgamated surface of the copper plates, gave evidence of a persistent tendency to escape amalgamation; the fineness of the amalgam, as measured in gold, being highest nearest to the battery, and giving place to a constantly-increasing proportion

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."
