Charles Desilver. Philadelphia, 1856.
13 1/2″ x 16 1/2″ [21 1/2″ x 24 1/2″ in mat and frame]. From “A New Universal Atlas,” Philadelphia, C. Desilver, 1856, p. 37. Wheat Transmississippi West 890. Moffat 42.
Colored by counties. Depicts roads, explorers’ routes, and suggested railroad routes. The Gadsden Purchase is marked “Proposed Arizona Territory.”
A brightly colored map produced for Augustus S. Mitchell’s atlas, and a map which claims to have been very updated. Desilver’s map was well suited for school geography. It was issued shortly after the Gadsden Treaty of 1854, therefore the current southern border with Mexico is depicted. A great number of Indian tribes are shown. Great Indian Treaty Ground is marked. The counties are shown in vivid color, with several counties stretching across Utah and New Mexico. Updates to the map include the addition of new trails, including Fremont’s and Kearney’s routes.
