Excerpt: ...that the efficiency of human energy was low, began to analyze operating conditions and the result of this analysis is one of the prime factors which enables American industrial labor to earn more per day than in any other country and American manufacturers to sell their products at a profit in countries where labor receives but 40 to 50 per cent of what it receives in this country. Until a comparatively recent date, efficiency engineering was confined to industrial plants and construction work. The results obtained in these lines has suggested its application to mining and from the very nature of the necessary working conditions in mining, it would seem that even greater results might be looked for than in other industries. The cost of production in mining may be divided into two parts, viz: Supplies and Labor. Of these the latter is the larger. Supplies--Supplies are usually considered practically a constant factor in the cost of production. They are, at least, less affected by a study of the details than labor. The importance of having excessive capital tied up in supplies is recognized, but it is doubtful if the interest on the amount necessary to carry an adequate stock of those in general use, would meet the loss due to the delays caused by continually running short of material. The amount of supplies which is necessary to cany, is affected by the standardization of equipment. For instance, nearly every manufacturer of power drills is glad to have his machine given a trial. If this trial were made on ground which were fairly uniform, a careful record kept of the performance of each machine and a comparison made of the records, it would probably result in one machine of each type being selected as a standard and a basis established...
