This is a later edition of Harper and Brothers' abridged two volume set that documents the monumental efforts of Lewis and Clark on their trek across the northwestern United States. Bound into the front of Volume I is a folding map, which is a reduced version compiled by William Clark in 1814, entitled Map of Lewis and Clark's, Track Across the Western Portion of North America, from the Mississippi to the Pacific Ocean.... The map is incredibly accurate and filled with extensive notes concerning the epic expedition. This edition is without the five additional plates found in earlier publications. Volume I has 371 pages, volume II has 395. 16mo. Both volumes are hardbound in their original green cloth covers with gilt titling on the spines.
