This atlas contains 65 (out of 66) beautifully rendered, steel engraved maps, including 33 (out of 34) double-page maps. There are several thematic maps and diagrams interspersed throughout the text that display the geology, weather, tides, agriculture, flags and animal kingdoms of the world. This 1864 edition is the last year with steel engraved plates, with many of the maps featuring vignettes, and some retaining the early strap-work style borders. It also has the desirable edition of the New Military Map of the United States which shows all state and territory boundaries rather than the limits of military divisions. And it features the double-page Civil War map Vicinity of Richmond. The double-page map of the state of New York is missing.

The Southwest map is the late 1863 - early 1864 edition in this series of maps. Arizona still claims the Southern tip of Nevada and has the county configurations of the old New Mexico Territory, with the addition of Castle Dome and Ewell counties in the south. The Utah/Nevada border is now at 115°. This is a completely new plate with extensive revisions in the watershed and mountain detail and several of the earlier notations removed. But it retains the note in the area of Quartzite, Arizona calling the area "exceedingly fertile and abundantly timbered and well watered." The map details the U.S. Mail routes, the Emigrant roads to California, the proposed railroad route through Utah, Nevada and California, and the Pony Express trail. The double-page map of Texas shows county development mostly in eastern Texas and only the three large counties of El Paso, Presidio and Bexar in the west. The panhandle, noted as the Staked Plains (Elevated Table Land, without Wood or Water), includes a large section that is unorganized. There is nice depiction of the wagon roads, many named, with several completed railroads. The inset maps include a 'Plan of Sabine Lake,' 'Plan of the Northern part of Texas,' and 'Plan of Galveston Bay.' The map of the Northwest shows the newly created territory of Idaho. The map of Minnesota shows the newly created region of Dakota with an undefined western boundary.

The maps are all very good with very light toning and an occasional spot of foxing. There are light damp stains on the edges of the text block, entering the border on some maps. The engraving of the flags has a long centerfold separation and a long tear at right. The front hinge has separated from the text block. The covers are moderately worn and stained, and the spine shows light wear.
