The problems presented by the culture, problems of historical reconstruction, Dr. Kroeber will also refer to, but discussion of the problems, of such subjects as culture areas, as the current phrase goes, as diffusion and acculturation, will not be presented in this book—it is a book of pictures. But if the reader wants to learn of how the problems are being followed up, he is directed to the bibliographical notes in the appendix. If the pictures remain pictures for him, well and good; if they lead him to the problems, good and better. Anthropology is short on students.
