A descriptive survey of the cultural institutions of the Dakota Indians discusses three stages of change: the tribal period, the reservation, and the city. The tribal culture was characterized by deep familial ties, generosity, and cooperation, with individualism in religious activities. Inconsistent governmental policy, different geographical conditions, and the introduction of Christianity produced cultural disorganization during the reservation period. The effect of urban culture on the Indian immigrant resulted in either an inability to adjust and withdrawal to the edge of the community or a commitment to the urban law of progress. Statistical measures are used only to indicate the strength and direction of cultural norms and views. Suggestions for further study are included. (JH)
