A study of conflicting races in the United States, by an expert foreign observer without sectional or racial bias.""--Chinese, Japanese, Mexican, Negro, Indian these are the races on which the writer concentrates his attention, though some of the others come in for more or less casual comment, by way of contrast in problems. He analyzes the history of each race in its relation to the conflicting forces of white versus red or brown or black --the impossibility of satisfactory assimilation the mistakes made in human and political handling of the problems -- the present status the chances for improvement in the future. One does not finish the book with any high degree of praise for the treatment accorded those of other colors by the American citizen or the American government. Not a book for general sale, but should interest those engaged in social work, Americanization (so-called), or students of racial problems. For college libraries; for public libraries.
