"The Sioux book gives the lore and logic of Indian life. It is rapid reading. Yet it unobtrusively overflows with Miss Sandoz's lifetime love and respect for these plains pioneers, and with her careful insights into their ways." —R. C. Nelson, Christian Science Monitor
"Here in these well established patterns of conduct . . . is a picture of an orderly, deeply respected way of life that is no more. . . . A worthwhile appraisal." —Kirkus
