The negro problem is, from our present outlook, insoluble. The most laudable of present efforts, that for industrial training, represented by Hampton and Tuskegee Institutes, and the work of Booker T. Washington, leaves the dire fact of two races side by side and yet unassimilated socially, politically, and, in large measure, economically. Two other possibilities, race admixture and caste, are both so repellent to white American thought, that they cannot be looked upon as solutions. Segregation in a separate state, or separate states, is a thorogoing proposal, but is practically impossible. Finally there is the conceivable, but improbable, event of the decrease and extinction of the negroes in America, Their relative number has declined since 1800,[2] but their absolute number still continues to increase. It seems probable that if European immigration were to be stopped that a very large migration of negroes from the South to the North and the West would occur to take places hitherto filled by unskilled immigrant workers. In the year 1915, following the check to immigration as a result of the European war, a very marked movement of this kind set in. If this occurred on a much larger scale it might result in greatly reducing the negro population in some portions of the South, and as the "natural rate of increase" of the negroes in the North is a negative quantity, it might cause the total negro population of the country to begin absolutely decreasing. § 4. #Favorable economic aspects of earlier immigration.# Regarding the immigration problem we are not confined to futile expressions of regret as in the last case. For by the "immigration problem" is meant primarily and mainly the coming of immigrants, and we can by legislation limit or stop their coming, if we will. The question at issue is whether their coming really is an evil or, on the whole, a blessing to the country.
