Aster- My investigations have been for the most 
part unaided by the opportunity of observing the 
collections of others. I hope the editing to the new 
edition of Michauex forest trees will fall into
able hands as you very justly observe the original
work needed many corrections.
You may calculate on my doing all in my power
to investigate the flora of my frontier during the ensuing
season but I am afraid that I shall not do all 
that I am desirous of doing as I have no one at present
to do my duty in case I leave my post.

I remain very Sincerely
yours M.C. Leavenworth
