My dear D
I must write one line to thank you for your letter of the 30
I hope, also, before end of year to hear that you have found time to write on the geographical distribution of the U.S. plants; & if my letter caused you to do this some year or two before you otherwise would have done it, I shall congratulate myself in private, at having done good Botanical work.
Pray believe me with cordial thanks | Yours very sincerely | Charles Darwin
