In the preparation of this study I have had the encouragement and support of Dr. Robert R. Moton, Principal of the Tuskegee Normal and Industrial Institute, Alabama, who generously placed at my disposal the facilities of the Institute's Division of Records and Research, directed by Mr. Monroe N. Work, the editor of the Negro Year Book. Mr. Work has cooperated with me in the most thoroughgoing manner. I have also had the support of the National League on Urban Conditions and particularly of the Chicago branch of which Dr. Robert E. Park is President and of which Mr. T. Arnold Hill is Secretary. Mr. Hill placed at my disposal his first assistant, Mr. Charles S. Johnson, graduate student of the University of Chicago, to whom I am greatly indebted. I must also make acknowledgment of my indebtedness to Dr. Carter G. Woodson, Director of the Association for the Study of Negro Life and History, Incorporated, Washington, D.C., for placing at my disposal the facilities of his organization.

The work of investigation was divided up by assigning Mr. Work to Alabama, Georgia and Florida; Mr. Johnson to Mississippi and to centers in Missouri, Illinois, Wisconsin and Indiana, while the eastern centers were assigned to Mr. T. Thomas Fortune, Trenton, New Jersey, a former editor of the New York Age, and a publicist and investigator of well known ability. It is upon the reports submitted by these investigators that this study rests. I can not speak too warmly of the enthusiastic and painstaking care with which these men have labored to secure the essential facts with regard to the migration of the negro people from the South.
