 My Dear Friend


 Yours of Sept. 4th reached me
 this morning, & I thank you heartily for
 the remittance, which came in capital time


 Do not put yourself out in the least to send
 me any more until the 23rd October, when
 some bills become due. Perhaps I could keep
 them back until 1st November-


 To keep the account simple I endorse the
 sum you send $100 on one of your notes as
 paid direct by you to me. When you want
 to pay Sprague for work done for Smithsonian
 you can replace it to him & thus settle your
 account with Henry.


 Agassiz is now back, says I shall soon
 have a proof from Sonrel.


 Sprague will now finish the rest of the plates
 for Genera vol. 2. & in the meanwhile try
 his hand at engraving to see if he can do it
 well, if not employ Sonrel, & take up your
 dozen plates & do them right off. They will
 be Fremontia, Batis, Portulacacae, Amarantha-
 etc. what else-


 Meanwhile, write your text if you can, & let
 Sprague have at it to aid him. If the plants do
 not [?] he will be sure to find it out as
 he works.
