Edwin Seward Puller, Your boy and his training (1916)
“ We hear much, in these latter days, of business and industrial efficiency. Experts in this line are able to systematize a business, a railroad, or a factory so that a given amount of labor will produce a maximum of results. Even such unskilled labor as shoveling is susceptible of scientific improvement. An efficiency expert employed by a great corporation decreased the number of movements of ore shovelers one-half, with a corresponding increase in tonnage of ore handled, and without an increase in the expenditure of physical energy. ”
