Drilling in Missouri in 1939 was marked by wildcatting in the northern half of the state. The total completions numbered 82, exactly half the 164 of 1938. There were 15 gas wells with an initial open flow of 6,383,150 cu. ft., 4 oil wells with about 40 bbl. initial production, and 63 dry holes. The wildcatting followed the widely publicized leasing activity in the Forrest City Basin in northwestern Missouri, northeastern Kansas, southeastern Nebraska and southwestern Iowa. It is worth noting that

Based on the belief that operating details are a definite contributing factor to major economies, this paper traces the development of crushing cavity design in Symons cone crushers to attain maximum liner utilization. Wear rates are analyzed and compared in this presentation and drawings illustrate succeeding design changes.

EMBRITTLEMENT of hard-tempered martensite (500°F embrittlement) appears to be coincident with the beginning of the third stage of tempering. During the first stage, primary martensite of steels containing over 0.25 pct C decomposes to a mixture of c carbide and martensite of appreciably constant carbon content close to 0.25 pct.' During the third stage of tempering, cementite forms. In steels with
