This is not a nation but a teeming nation of nations,"" --and Adamic, author of My America and of Grandsons has already shown in these books his awareness of this as a problem to be faced. In this new volume, he has brought together the results of years of intensive study, personal interview, constructive efforts towards education for the purpose of building the values -- and leveling the intolerances and prejudices involved in race and nationality and groupisms. A collection of personality studies, bits of human records, drawn from people of the Balkans, of Poland, Czechoslovakia, Holland, Finland, men and women who help make America. A composite human document, each part contributing to better understanding of the problem. There has never been a time when racial prejudice was more alive -- or when it has been more essential to face its problems with intelligence and good will. Here is a first step.
