Immigration
(1913)
“ Such movements as these have usually resulted in a nation’s losing the most valuable elements of its population. The cause has usually been religious.A different type of forced migration has been exemplified in the slave trade. In this case the migrants are compelled by actual force to go from one region to another specified one. The movement of the Africans to America is a familiar example. The motive is the economic one of securing a supply of labor at a minimum expense. Still another type is furnished by the penal colonies, such as have been established in Australia and elsewhere. ”
