André Michaux's Travels into Kentucky, 1793-96; François André Michaux's Travels West of Alleghany Mountains, 1802; Thaddeus Mason Harris's Journal of a Tour Northwest of Alleghany Mountains, 1803.

A compilation of three travel journals documenting journeys across the trans-Alleghany West, combining close botanical observation, descriptions of landscapes and settlements, practical notes on cultivation and timber, and reports of encounters with local inhabitants. The texts alternate daily journal entries and scientific commentary, supplemented by maps, illustrations, and editorial material, and together they chronicle routes, plant collections, and experimental attempts at transplantation while also recording the social and geographic conditions encountered during exploration.
