First edition. The route Simpson explored in 1859 shortened the distance to California by 250 miles, and was adopted by the overland mail, pony express and telegraph. Submitted in 1859, the report on the explorations was not published until this edition because of the Civil War, although parts of it appeared in Simpson's "The Shortest Route to California," Philadelphia, 1869. In addition, this volume offers the first printing of Edward M. Kern's diary of Fremont's 1845-1846 explorations.
