FIRST EDITION IN ENGLISH, preceded by the first edition in French, published in New Orleans in 1824. Beltrami, a member of the Long Expedition and a political refugee from Italy, traveled up the Mississippi River as well as the Red River to what is now Minnesota in their search to find the source of the Mississippi River. His writing is evocative. "He had much to say of the aborigines, and expatiates upon the natural history and scenery of the region he visited with intelligence and enthusiasm" (Tuckerman). After tension arose with Major Long, Beltrami continued his search alone. He discovered Lake Julia and claimed it was the source of the Mississippi River. The first edition met with harsh criticism, to which the preface to this edition responds by adding 2 letters, one describing western Pennsylvania and the other his ocean voyage. Buck 181; Howes B-338; Monaghan, pp.10-11; Rusk, The Literature of the Middle Western Frontier, p.89; Sabin 4605; Tuckerman, America and Her Commentators, p.342; Wagner-Camp 26a:2 (with p.545 misnumbered 54 as the present copy).
