from Hastings telling when it sails), and to reach 

 Austin and Fredericksburg in time to accompany the 

 troops that are about to be sent up, by a new road, 

 across a new country, to El Paso, in New Mexico. 

 Look on the map (Wislizenus) and you will see the 

 region we mean him to explore this summer ; the hot 

 valley of Rio del Norte, early in the season, the moun- 

 tains east, and especially those west in summer. He 

 will probably stay two years, and get to Taos and 

 Spanish Peaks this year or next. We shall have 

 government recommendations to protection, and let- 

 ters to an officer (commanding) who, through Henry, 

 has already made overtures to collect himself or aid in 

 the matter.

I have finished all the copy of " Genera Illustrata," 

 vol. ii., at length; the printer has yet two or three 

 sheets to set up. The plates are working off in New 

 York. It will now soon be off my hands. It is long 

 since I have done anything at Exploring Expedition 

 plants. I am now going at them. It is a shabby, un- 

 satisfactory collection. . . . 



CAMBRIDGE, November 2, 1849. 



. . . Sorry I am that you could not be here while 

 Harvey is here ; he will be south by Christmas. He 

 desires me to say that he expects to spend the first half 

 of December in New York at Dr. Hosack's, and will 

 be most glad to see you. I am sure you will like him. 

 We are perfectly charmed with him. A quiet, unaf- 

 fected, pleasant man extremely lovable. He works 

 away at a table in my study. His course is a very in- 

 teresting one. He is a beautiful writer, but not very 

 fluent extempore, though with more practice he would 

 be a fine lecturer. He has a good audience. . . .
