Washington, single sheet (25.75 by 23 inches). ***CONTENT: This is the celebrated ""General Map"" issued with Volume I of Emory's monumental ""Report on the United States and Mexican Boundary Survey"". Major Emory was assigned to the Boundary Commission after the Mexican War by President Franklin Pierce. No sooner was the first Survey completed, the Gadsden Purchase necessitated another survey, which is summarized in Emory's report and this map. The map shows the topography of the region from the Mississippi to the Pacific, and is one of the foundation maps for the western U.S. and northern Mexico. It represents the amalgamation of fifty years of government-sponsored western explorations, beginning with Lewis and Clark, and portrays the first reasonably correct cartographic picture of this vast region of the West. Meticulous engraving highlights the topography of western mountain ranges, and the map also illustrates water courses, geographic and cultural features (towns, forts, transportation routes, etc.), as well as ""unexplored areas"". ***CONDITION: The map is complete and near Fine, with no tears or repairs. The paper is supple, fresh, clean, and bright, with very minor creases. This is a handsome copy, one of the best I have seen. Nickles 349 (in part). BMNH 2178. Wheat 916.
