My own field work was devoted to an attempt to trace the patterns of change among these people since the entrance of the white man into their area. To this end I spent a great deal of time with older informants, but my work was not exclusively “salvage ethnography.” Many aspects of Washo culture have changed dramatically in the past century; this is particularly true in the area of material culture and subsistence activities. On the other hand, I was impressed by the tenacity of the less material aspects of the culture. The always-difficult-to-define world view or ethos of the Washo, which so clearly separates them from other cultures, is very much an entity expressed in the attitudes and actions of the Washo Indians, whether they are oldsters who can remember many aspects of the “old days” or children who have not yet entered the newly integrated schools of Nevada. This continuity seems most clearly expressed in the area which we subsume under the title “Religion.” Almost all Washo, even the youngsters, are familiar with, or at least aware of, Washo mythology, attitudes about ghosts, spirits, medicine, and a number of ritual actions and beliefs which are common elements in Washo life today. This is not to imply that Washo religious activity has not been affected by the tremendous changes which have taken place in western Nevada and eastern California. I suggest that rather than disappearing under the withering rationalism of civilization the religion of the Washo has simply altered and expanded to serve the Washo in new situations. In this work I take the broadest possible definition of religion, conceiving it as any institutionalized activity or attitude which reflects the Washo view of the cosmos. In so doing I have included a number of categories which may not generally be considered suitable for inclusion under the heading of religion. Stewart, for instance, includes shamanism, curing, special powers of shamans, miscellaneous shamanistic information, guardian spirits, destiny of the soul, ghosts or soul, and jimsonweed. My own work includes some of these specifically, incorporates some under other headings, and treats a number of subjects not included in the list given above. The reason for this approach is practical rather than theoretical or philosophical. As anthropological definitions of religions are extremely varied and the activities described as religious under various definitions cover a greater or narrower range, it seems valuable to include as many activities as possible in a purely descriptive work. The goal of this paper is to make as much information as possible about the religious and ritual activities of the Washo available to scholars who may be interested in religion. The inclusion of as many fields of activity as possible permits them to select information which they feel pertinent to their interests.
