“ Manufacturers recognize the necessity for comprehensive statistics in the manufacturing branch; they realize that they must know what their goods cost to manufacture; but in comparatively few enterprises is the importance of commercial costs recognized.In the factory, costs are figured down to the most minute detail; what it costs to perform each operation on every part of the completed whole is known; the efficiency of every man—what he costs in wages, in power, and general expense, and the cost of every bit of material he uses—all of this is told by the cost accounting system. ”
