Living in America today are many hundreds of thousands of people whose lives are characterized by continual movement each crop season from town to town, from state to state, and from region to region. There are 3 large-scale pathways (streams) the migrants follow: (1) along the Pacific Coast, from southern California to Washington; (2) from the south-central region of Texas, Louisiana, and Oklahoma and terminating in states like Minnesota, Michigan, and Wisconsin; and (3) along the Atlantic Seaboard, from Florida to New England. The migrant labor forces are made up of Mexicans, Negroes, and Whites living under conditions characterized by poor housing, bad sanitation, poor diets, and inadequate medical care. In a very real sense the migrant farmers form a "subculture," living apart from the rest of the nation in many ways. They not only live apart, but they feel the implications of their behavior. The author states that, on the basis of his observations, it is this isolation that specially characterizes migrant farm life. (EJ)
