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 Iustrata,” 
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. Iam now going at them. It is a shabby, un- 
satisfactory collection. . . .

.. . Sorry Iam 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. Iam 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. .. .
