This is the second Senate issue of the book, with Emory's rank given as Brevet Major, and with slight changes in the spelling of the captions. A superb study by topographical engineer and scientist Emory of the lands newly wrested from the Mexican government. As Wagner-Camp notes, "his report was a major contribution to the geographical knowledge of North America…the report includes sections on the plants and animals, as well as on the geology and the prehistoric town sites and other archeological remains. Emory's descriptions of the various Indian tribes that he encountered were steps toward the newly-forming discipline -Anthropology- concerned with primitive man."
