My Dear Sir

I have in my possession
a collection of plants which I make
during teh year 1849 & 50 in wht Creek
& Cherokee country while attached
to the Creek Boundary Survey as
physician & naturalist under the
command of Capt. L. Sitgreaves &
Lieut. Woodruff Top. Engr. [topograhical engineer] U.S. Army.

Also a collection made between San
Antonio & El Paso Texas during the
spring of 1851 as I passed through
that country whilst attached to the
party under the command of Capt.
L. Sitgreaves. U.S.A. oon our way to New
Mexico to explore the Rivers Zuni
Great & Little Colorado of the west.

I am directed by Col. Abert
to write and ask if you would
undertake the  naming and 
describing of them should any of them
