Washington Meridian. Hand tinted full color. Relief shown in hachures. Shows railroads, settlements, counties, waterways, and lakes. Engraved. This is a very unusual and wonderful atlas - it combines the most complete Asher & Adams atlas map set (the same grouping as the late 1874 issue, but updated - see our #41) bound unfolded on edge (this is a huge book) with beautiful illustrations opposite each map of industrial establishments, products, and machinery. It has become very scarce. Its sheer size probably meant that the edition was small in number. Several of the maps are updated and copyrighted 1875; Colorado is substantially changed with the introduction of mountain ranges with "Gold, Silver, Copper and Lead Mineral Belt" overprinted on them. There may have been an 1883 issue of this atlas by George Adams, not listed in Phillips.
