"The Principles of Scientific Management." By Frederick Winslow Taylor, New York: Harper & Brothers, $1.50. One of the live topics of the times is scientific management as applied to the industries of the nation. The little volume above mentioned is a classic in its field. Its author, who has now retired from the active work of introducing scientific management into manufacturing establishments, spent a large part of his life in developing his chosen subject at the Midvale Steel Works and the works of the Bethlehem Steel Company. A genius for the work combined with infinite patience and unremitting study brought forth the remarkable system which is now being studied and applied by engineers and managers throughout the land.
