          Under Eriogonum abertianum you say "a fulll account of Mr.
[William] Gambel's plants by Mr. [Thomas] Nuttall will soon be published in
the journal of the academy of Philadelphia." This would
be very useful to me. Under Abronia mucranthum is [Torr.?] in
Iremne iss report P. 96. This you could doubtless furnish me. So 
under Ipomea leptophylla. So "Torr in m. Lyc. N York 2, p.248, t,4.
under Quercus [Torreyi?]. Gray & Engelmann have described some
plants of Proceedings of the American Academy 1. p. 50. Any or all
of these and any others of which I have no knowledge would
be most acceptable to me who have now the prospect before
me of a residence of two or more years in the wilderness. Please
confer with Dr. Gray on the subject and whatever you may 
collect send to Dr. Engelmann and instruct him to forward
them to me "care of Col J.D. Graham" of the Boundary Commission. 
Pray don't send me any thing via San Antonio
for the stupid P.M. will let it lie there forever & ever Amen.
Beside there is no organized mail between San Antonio and
El Paso but only a provate express. Col Graham says he counted
twenty-odd letters for Col. [John] Munroe in command at Santa Fe lying
in the P.C. at San Antonio - some of them too directed "via Fort 
Independence" [carat: Mr.?] franked too & prepaid. Pray send me the sheets
of my plants as fast as published and by the Western Mail.
If they reach me - well if not - it is no great loss. If you have 
a provate opportunity don't fail to send me any thing [carat: mentioned above] of
reasonable bulk & weight which you may be able to procure.

July 2 I have just remitted my packages (4) by the returning train
and a barrel of Cactaceae to Dr. Engelmann. My catalogue of
plant runs up to about 575 including of course some duplicates.
I have entrusted them to the tender mercies of wagon master
teamsters and quarter-masters [carat; merely] tied up in bundles and wrapped
in large wrapping-paper.

If Dr. Gray has returned from Europe you can send him this letter. I have
not written to him though I may do so soon in which case I shall send
