In his interpretation of the Lewis and Clark Corps of Discovery Expedition across the continent, 1804-1806), Swagerty (history, U. of the Pacific), author of numerous articles on the fur trade, argues that the expedition's success was due largely to Corps members' adoption of Indian ways (e.g., diet, dress, transportation, diplomatic protocols including women's role in mediation). This "Indianization" led to their greater awareness of differences among native tribes, and helped shape subsequent white-Indian relations. The two-volume set includes maps, color plates, other illustrations, excerpts from the journals and other supporting information. The Arthur H. Clark Co. is an imprint of the University of Oklahoma Press. Annotation 2012 Book News, Inc., Portland, OR (booknews.com)
