The science and nature books which Dr. Fenton has done over the years have taken their place as authentic and vivid. This is a somewhat new departure for him, as he- in collaboration with Alice Epstein -- tells the story of the cliff dwelling Indians of Arizona some 800 years ago. These were the Sinagua Indians; they had farms on level ground, though their homes were in the cliffs, made of stone and clay. We follow the pattern of their lives,- their industry, their division of labor, their tools, their pottery, their dances dedicated to their gods, their means of communication, their animals, and so on. The rhythmic prose in use here sometimes seems to hamper the natural flow of thought, but the substance of the text provides another facet to the study of the American Indian, whether as a school supplement or in scout work.
