The Fourth World of the Hopis

by Harold Courlander. Crown, $6.95. Mr. Courlander has spent years collecting oral material among the Hopis and has arranged it in what he modestly hopes is correct chronological sequence from Creation myths to early wanderings to collision with the Spaniards. The casual reader is likely to find more confusion than enlightenment in the myths, but the later sections of the book, giving the Hopi version of established historical events, are another story and a good one.
