There is a definite market among young people for descriptive material on the Peace Corps. This is a short, lively account of a privately financed forerunner to the Peace Corps, known as Operation Crossroads Africa. The author in the summer of 1960 accompanied 183 young people to Africa where they worked with Africans performing manual labor, clearing bush, building schoolhouses and so on. The main purpose of the book is not to discuss the work performed but to point out the alteration of attitudes among the participants. Emergent Americans are those who understand a world in which the white man is no longer master and the African no longer colonial. High school and college students will be interested to learn how this transition took place among their contemporaries only a year ago.
