The principal aim of this study is to present statistical and other informational data concerning the numerous labor problems that arose in the United States during the recent war, and to outline the development of war labor administration. The data were gathered during the war period and the study was completed shortly after the cessation of hostilities. No pretense is made to discuss the developments that have taken place in the period of reconstruction, except where it has seemed necessary to add data to round out certain phases of the presentation. The conclusions in the final chapter were formulated in the light of the war experiences of the United States and, altho the months subsequent to the signing of the armistice have uncovered developments that may seem to invalidate some of the conclusions regarding the future relations of capital and labor, the author is still of the opinion that his analysis has adequate basis in fact and that future developments will sustain his conclusions.
This opportunity is taken to express the writer's appreciation of the very valuable criticisms and suggestions made by Professor John A. Fairlie of the University of Illinois, who has read the manuscript. The author is especially indebted to his wife, Anna E. Watkins, whose constant coöperation has made this study possible.
