28 AUTOBIOGRAPHY. [1843. 



the first edition of my " Botanical Text-Book ; " it was 

 in the course of printing when I was appointed to the 

 Fisher professorsliip, so that I could put that title on 

 the title-page, and have a text-book for my class. 



My first session of college work was over about 

 July 1, 1843. The treasurer, Mr. Samuel Eliot, had 

 given me leave to spend a small sum in replenishing 

 the Botanic Garden. I met my friend and corre- 

 spondent, William S. Sullivant, who had taken strongly 

 to mosses, early in August, on the Alleghanies beyond 

 Frostburg, Maryland (the railroad went only to Cum- 

 berland), he coming from Columbus, Ohio, I from 

 Cambridge. There we bought a span of horses and 

 a strong country wagon, and set out on the mountain 

 expedition, some sketch of which is given in the 

 " American Journal of Science " for January, 1846. 

 (The first journey is more particularly detailed in 

 the " American Journal of Science," xlii., no. 1 ; 

 1842 ?) When Sullivant left me, at Warm Springs 

 on the French Broad, anxious to get home, I was left 

 in a pretty lonely condition.
