Excerpt from Anthropological Papers of the American Museum of Natural History, 1916, Vol. 17 The horse culture complex of the American Indian offers an excellent opportunity to study diffusion, because most of the essential facts are obtainable. The horse was introduced by Europeans at an early date and spread ahead of interior exploration. In particular, many of the tribes west of the Mississippi River became. Horsemen before their discovery by Europeans. The history of horse introduction is briefly outlined in the American Anthropologist, Vol. 16, N o. 1, pp. 1 - 25. The investigation here reported is the intensive study of collections of riding gear and horse-using appliances to be found in anthropological collections. The material avail able in the Museum gives us a representative series for each important tribe in the horse-using area so that we may proceed in confidence. A preliminary statement of the results attained in this study were published in the Proceedings of the National Academy of Sciences, Vol. 1, p. 254. In the selection and comparison of specimens the writer has been aided by Mr. William A. Sabine, assistant in the Museum, whose great knowledge of specimens and their distribution was indispensable to the task. Other acknowledgments are due to Mr. S. Ichikawa for the illustrations and to my secretary, Miss Bella Weitzner, for gathering reference material.
