Drilling for oil and gas in Missouri continued at a slightly lower rate than has been prevailing. A summary of operations for the past few years as compiled and published by the Missouri Geological Survey and Water Resources is as follows: Two oil pools are being developed in Cass County. Neither area has been drilled completely, and detailed descriptions will not be given at this time. In the Endicott pool in the southern part of T. 44 N., R. 33 W., oil is found in the Warrensburg sand, which is now considered to be the Big Lake sand of eastern Kansas. The top of the sand is about 125 ft. below the Herthalimestone. The best well is reported to have made 14 bbl. per day for the first four days. The oil is 30" to 32' BB. gravity. This is the only pool in the state, aside from the older areas on the east and west edges of Lees Summit, Jackson County, that is producing oil from the Warrensburg sand. Drilling continues in the Knoche pool in the central part of T. 46 N., R. 33 W., where the oil is found in the Squirrel sand. The oil produced by both these pools is sold by truck in Kansas City.

Previous articles in this column have defined the manpower situation as it. applies to the coal industry. There is at present a shortage of experienced managers, mining engineers, technicians and skilled workers. The extent of this shortage is controversial, but it is sufficiently important to have received the serious attention of coal industry people at all levels. It has also been discussed by union officials, educators, government agencies and trade publications as well as other communications media. Discussion is not enough, however. A plan of action is needed. Some suggestions for such a plan are presented here. First, the coal industry must interest itself in government training programs. The U.S. Government (primarily the Bureau of Mines and HEW) is planning to spend or is spending millions of dollars to educate and train technicians, inspectors, engineers and miners. The new Federal Health and Safety Academy at Beckley, W. Va., for example, will involve an expenditure of $20-30 million for the physical plant alone. There are encouraging signs that the present hierarchy in the Bureau of Mines intends to seek the advice of mining educators on some of these projects, but industry should also demand a voice in the policy to be followed in making these expenditures.

H. C. WEED*—Referring to the use of "dummy fuse" for checking the shots in chute blasting operations, I believe that an even better practice is to blast the chutes with no delay electric blasting caps. Permanent wires can be strung through the grizzly lines and the lead wires from the shots attached to these lines. Using this method, no time is lost in spitting the individual fuses. The possibility of a fused charge becoming dislodged by previous shots and falling into the chute below is eliminated and there is no chance of a man walking back into his own blast. A small hand twist blasting machine or a radio "B" battery can be used to fire the shots if the lines are fired individually. If so desired the entire area can be blasted at once by a switch at the manway or in the drift below. providing a sufficient source of electricity is available. In case a switch is used, proper precaution for locking the switch must be provided. R. H. WIGHTMAN (author's reply) —We do use electric blasting when the number of shots is large; but we have found it more satisfactory to use fuse and caps for individual shots on the grizzly.

THE fall meeting of the Petroleum Division of the American Institute of Mining and Metallurgical Engineers will be held in Fort Worth on Oct. 19 and 20. The Texas Hotel will be headquarters. for this meeting, the technical sessions being held in the ball-room of the hotel. During the evening of the nineteenth a smoker will be held at the Fort Worth Club. In working out the program for this meeting, J. B. Umpleby, vice-chairman for production engineering, considered it especially desirable to offer as complete a discussion as possible of the subject of air-gas lift, its theory and practice, and its relationship to gas-oil ratios. The entire first day will be devoted to sessions on this subject. One session of the second day will be devoted to the use of electricity in oil-field operations and the second to the handling of congealing oils and paraffin. In addition to this program there will be one or more sessions when petroleum engineering research problems will be discussed. This meeting of the Division is primarily devoted to production engineering, as will be seen from the pro-gram. During one of the sessions, however, a brief review with forecasts of the production situation will be presented.

The time effect in reheating certain steels below the critical range is very marked. The increased toughness, shock-resisting power, and machinability of steel subjected to a long, high drawing temperature has been thoroughly demonstrated and is of practical importance, particularly in the manufacture of "smokeless" rifle-barrel steel. The time effect in tempering is most important when a maximum drawing effect is desired, in which case the highest physical properties as well as ease of machining are important considerations. These are the conditions in drilling a rifle barrel. A hole, 0.30 in. in diameter and 24 in. long for the Springfield rifle, and 30 in. long for the Russian military rifle, has to be drilled in the heat-treated material. This barrel-drilling operation is probably the most difficult one in rifle manufacture, and anyone who has been connected with rifle manufacture knows how seriously production is affected when "hard" or non-uniform steel for barrels is encountered. The importance of high physical properties (tensile strength, toughness and resilience) in a rifle barrel is obvious. The physical properties of two different lots of barrel steel are given below. The first lot, No. 1, gave serious trouble in the drilling operation; the second gave no trouble at all.

In the fall of 1937, the Department of Mining at Penn State was being reorganized and the department records were moved to the Records Room of the School. An inventory of the contents of the vault disclosed six folders of records that had been forgotten for 27 years. These files, apparently preserved by former Dean W. R. Crane, plus the recollections of several former members of the Association described below, unfolded the "lost chapter" in mineral industries education.1 It was apparent at an early date in technical education that an association of mining schools with common interests and problems would have definite value. By 1902 sufficient interest had developed in this idea to cause the holding of a preliminary meeting for the purpose of organization. The first meeting was held at the Montana School of Mines on September 4, 1902. At that time, officers were elected and resolutions were adopted that there be formed an organization to be known as the National Association of State Mining Schools. The object and purpose of this Association was to advance the interests of state mining schools in every way, particularly by promoting legislation for the benefit of such schools. The second meeting was held September 10, 1903, and a resolution was passed that the American Mining

Frank Owen, El Perú Venezuela (communication to the Secretary): Mr. Cragoe's accurate description of the rich and extensive mines of the Frontino and Bolivia Co. is of much interest to those acquainted with Colombian mining. While the labor in that part of Colombia is, of course, admittedly far inferior to that of white miners, it is,. nevertheless, decidedly superior to that available in other parts of the republic, and in the northern mining regions of South America generally. The Autioquenos have been miners for several generations, and many of those employed at the Frontino Co.'s works have been brought up at the mines, which is a distinct advantage. The ground encountered in the surface-workings of that district being very treacherous, they are skillful timber-men, every miner being able to put in his own timber in tunnels, stopes, etc., so that, except for the main shafts, where sawn timber is used, special timber-men are not required. In the shallow workings it is the custom for a miner to come out of the mine into the thickly-wooded bush and select and cut the timber he requires, which he will then take into the mine and put in

The age of specialization has made man increasingly dependent on a larger number of different metals and minerals. Overexploitation during World War II and lavish squandering of irreplaceable mineral wealth in the past has resulted in the rapidly approaching exhaustion of some of the major domestic ore sources. History clearly points out that the United States cannot continue to be a world power on an "import to survive" policy. A constructive program of development and appraisal of the nation's mineral wealth, including the planned conservation of her resources, must be adopted. Strictly speaking, conservation of minerals must mean the orderly exploitation of our resources and the prevention of waste in use, with due regard for the future. Real concern for the future may not extend beyond a few generations. Eventually science and invention should take care of the problems arising from shortages of some minerals, and the national defense aspects of domestic deficiencies can be provided for by stock piling and other measures. Early conservationists had this viewpoint; but with a rapidly developing industry and population, a farsighted policy that would deny full realization of immediate ambitions became unpopular. Consequently, the politically minded conservationist broadened the concept to include "prudent use of resources" and brought under the conservation umbrella
