Despite centuries of contact with Spanish America and Anglo-America, the Hopi Indians retain a strong cultural tradition of their own. The snake dance is a significant, but overpublicized and often misinterpreted, aspect of that culture. Forrest does not warp the facts, yet his personal observations add nothing to the published anthropological accounts, which he quotes liberally. He does not bring out quite forcibly enough the days of other ceremonial preparations and observances which precede the snake dance, nor does he show how the ceremony fits into the total pattern of life. It stands more or less in isolation as a curious event. The photographs are another matter. Taken by the author in the early years of this century, before the total ban on photography went into effect, they are valuable documents.
