Ohio, and Virginia, crossing the Alleghany 
mountains of Virginia, and returning by the 
Alleghanies of Pennsylvania, always on foot. 
Next year, 1826, I left Kentucky and settled

Several botanical excursions and journeys 
were undertaken in 1831, in Delaware, New 
Jersey, and the Taconick mountains. While

mountains. 
In the year 1833 I proposed to visit the 
Apalachian mountains as far as Alabama : but

again in the Cotocton mountains. — In a second
