Chief among the economic causes why men leave home are (1) seasonal occupations, (2) local changes in industry, (3) seasonal fluctuations in the demand for labor, and (4) periods of unemployment. The cases of homeless men studied in Chicago show how these conditions of work tend to require and to create the migratory worker. 1) The industrial attractions of seasonal work often make a powerful appeal to the foot-loose man and boy. A new railroad that is building, a mining camp just opening up, an oil boom widely advertised, a bumper crop to be harvested in Kansas or the Dakotas fire the imagination and bring thousands of recruits each year into the army of seasonal and migratory workers. 11. Fifty-eight years old and born in Belgium. He came to this country with his parents in 1882. His family moved to a farm in northern Wisconsin where they remained several years. The boy worked during his spare time in the woods. His father soon became tired of farming and decided he could do better in the coal camps of southern Illinois, for he had been a miner in Belgium. After the family moved, the boy grew restless in the mining town and decided to return to his old home town in Wisconsin where he could get a job in the woods which was more to his liking. For several years he divided his time between the northern woods in winter and the mines at his Illinois home in summer. But he never liked coal mining and later began to go to the harvest fields for his summer employment. Sometimes he worked on railroad construction or at other seasonal work. He has spent several winters in Chicago, and usually (he says) he has been able to pay his way. However this year, 1921-22, he has been eating some at the missions. This case shows the steps by which a stationary seasonal worker becomes a migratory worker. It indicates how easily and naturally the migrant may sink still lower in the economic scale until he spends his winters in Hobohemia “feeding at the missions.” 2) Local changes in industry dislocate the routine of work of the wage-earner. The timber in certain regions gives out, mines close down when the ore is exhausted or when prices drop, or in the reorganization of an industry a branch factory may be abandoned. Under these circumstances, certain workers are compelled to look elsewhere for employment. Those who are free to move naturally migrate. The following case is that of a migratory worker who with the passing of the West finds it difficult to make the necessary adjustment.
