Washington DC, 1850. First Edition. Good. Text: 8vo (224 x 140 mm). 14, [2] pp. (including final blank leaf), some foxing. COMPLETE WITH LARGE FOLDING LITHOGRAPH MAP OF MEXICO, with U.S. Army routes in red (659 x 500 mm). Folds and short repairs where attached to text, light browning. Recent sympathetic drab wrappers, front cover lettered in manuscript. First edition of this excellent map illustrative of both the Mexican-American War and the cartography of Mexico, prepared by members of the U.S. Army Topographical Engineers. Our map is accompanied by the essential text which is not always present. Herein "cartographer M.L. Smith (Lieutenant of the Topographical Engineers) writes to J.J. Abert (Colonel Corps Topographical Engineers) paying homage to the accuracy of Baron Humboldt's map of the Valley of Mexico and stating that it was the only one in which they placed confidence for moving troops in to capture the city. He remarks, however, that he believes that the present map is the first survey of the valley ever made by triangulation. His colleague, E.L.F. Hardcastle, supplements the report with memoirs of the march made in his journal as events occurred. This sparse but pithy report has excellent details on military engineering."
