Presentation Abstract... Selected Prose of John Wesley Powell:   John Wesley Powell: "Soldier, Explorer, Scientist"; "Pioneer Statesman of Federal Science"; Director, U.S. Geological Survey, 1881-1894; Director, U. S. Bureau of (American) Ethnology, 1879-1902. Powell: Since my last writings and public appearances, many words have been penned, many works published, and several biographies made available, among them Lincoln, Darrah, Stegner, Terrell, and Worster (see: Marcia Thomas, John Wesley Powell: An Annotated Bibliography; and Earle E. Spamer, Bibliography of the Grand Canyon and Lower Colorado River). Though thousands of words have appeared on the pages and innumerable thoughts have crossed the minds, I have been particularly silent in response. I take this opportunity to join the discussion at the 2007 Grand Canyon History Symposium to reiterate my views of western reclamation and arid lands, and the implication of science in their implementation.
