          My dear Sir,

Your letters of the 10th & 13th were recieved
together last night. Far from wearying of your
letters I never see the handwriting on the address
without pleasure and your enthusiasum for botany
handly surpasses my own, although scarcely
justified by my slight knowledge. As you
know have the most leisure please write
whenever you have any suggestion or information
to communicate and I will answer as promptly
as pressing business will now permit. I know
answer seriatim. Unless Geyer be the German
botanists I have no idea who it can be, but
we will try in the coming expedition to go
beyond him. I will send you the notes on
the Fremontia tonight and will take care
about the extra copies, and more of the report.
I like your idea of publishing from time to
time when I am gone and if I can make a
safe opportunity I will send you a collection from
the foot of the mountains in the Summer. We
can arrange to have as many plates paid for
