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." The larger House of Representives issues of the report, of which this is the first (30th Congress, 1st Session, Doc. 41), to contain the reports of Lieutenant Abert, Colonel Cooke, and Captain Johnson as well as that of Emory. The two maps are "Map of the Territory of New Mexico" and "Sketch of part of the march & wagon road of Lt. Colonel Cooke." The very large folding map was not originally issued for this House issue, but both maps are bound-in towards rear. Lacks two of the plates.
