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. However, it does include the large folding map, which Wagner-Camp does not call for with this issue. 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 archaeological remains. Emory's descriptions of the various Indian tribes that he encountered were steps toward the newly-forming discipline -Anthropology- concerned with primitive man." Senate Executive No. 7, 30th Congress, 1st Session. Cowan p.195; Graff 1249; Howes E145; Wagner-Camp 148:2; Wheat Transmississippi 544; Zamorano Eighty 33.
