This study examines the Katcina phenomenon among the Tusayan villagers, treating Katcinas as supernatural personae embodied in masked dancers and ritual dolls. It presents a calendrical sequence of ceremonies, methods for fixing ceremonial dates, and a tentative classification that distinguishes elaborate rituals (including seasonal return and powámû rites) from abbreviated observances. Detailed descriptions cover mask types, regalia, symbolic motifs, and positions of celebrants, accompanied by plates and figures. Comparative remarks relate these practices to other Pueblo communities while noting cultural affinities and limitations of available data. The author emphasizes careful empirical observation and warns against superimposing Western notions of deities on indigenous ritual concepts.
