Report Foreword: Migratory agricultural workers made an outstanding contribution to the war effort by harvesting food crops on the Atlantic Seaboard. Without their contribution, the armed forces, the nation, and the world would have had less to eat. The Agricultural Extension Service aided these migrants to overcome travel and other difficulties and so to continue their accustomed seasonal visits to areas of need. In the earlier war period, without this assistance, the number of migratory workers decreased so greatly that it was necessary to begin replacing them with foreign workers. This is a record of this migration in the war years and is recognition of the national service rendered by these thousands of farm workers and of the assistance rendered then by the many Extension Service employees who were so untiring in their aid.
