Much of the material on which the statements in the preceding essay are based is information collected by the University of California's Ethnological and Archaeological Survey of California since 1901 and as yet unpublished. Of old accounts dealing with the religion of the Indians of California, the best is by the Franciscan missionary Boscana, entitled Chinigchinich and published in the 1846 edition of a volume by A. Robinson called Life in California. It deals with the Shoshonean Indians of Mission San Juan Capistrano. An occasional reference of value may be found in other works, such as Venegas' History of California. The series of translations and republications of early explorers in California and the Southwest, published in the Land of Sunshine, later Out West, beginning in 1899, is also convenient, though naturally it deals but incidentally with religion. Reid's account of the Indians of Los Angeles county, published in an early Los Angeles newspaper and republished by Alexander Taylor in the fourteenth volume of California Farmer in 1861, is particularly good, though less so on the side of religion than on most others. Stephen Powers' Tribes of California, issued in 1877 as the third volume of the Contributions to North American Ethnology, a government series, deals with the Indians of the greater part of the state and contains many references to their religious life. Powers is however often very inexact, and the value of his work is in its comprehensiveness rather than in its reliability. An important work is Creation Myths of Primitive America, by Jeremiah Curtin, which consists of a collection of myths from the Wintun and Yana of Northern California. The differences of form which these myths show from most Indian myths that have been published in translation are apparently chiefly due to the method of their presentation by the author. Curtin's introduction is very suggestive but exaggerated. Professor R. B. Dixon has brought out a paper on Maidu Myths, and another, a great part of which is devoted to religion, on the Northern Maidu, both in the seventeenth volume of the Bulletin of the American Museum of Natural History. These two contributions are among the most careful studies as yet made by a trained observer in any part of the state. The same author has also published briefer articles on Some Coyote Stories from the Maidu Indians of California, System and Sequence in Maidu Mythology, and Some Shamans of Northern California, in recent volumes of the Journal of American Folk-Lore, and on The Mythology of the Shasta-Achomawi in the American Anthropologist for 1905. Professor P. E. Goddard has published Life and Culture of the Hupa, the last portion of which refers to religion; and Hupa Texts (with both interlinear and current translations), almost all of which are religious in character. These two papers constitute Volume I of the University of California Publications in American Archaeology and Ethnology.
