My Dear Sir

The balance of my
collection having arrived I thought
it best to write to you and
ask if you could undertake
to name [crossed out: them] and describe them
(should any prove new) immediately
as Col. [J.W.] Abert is anxious to
have them finished so as to
have the report with all the
drawing accompanying it
ready to hand in at opening 
of Congress. If you do not think
you will be able to undertake
and finish them soon do you
think do Gray can? As it is 
now getting so late in the season
there is no time to be lost.

How have you got on with
the Texas & Arkansas collections?
