Worthington, Sept. 6th. 1833.

Dr Torrey
Dear Sir

I received your letter
last evening, and am much obliged to
you for the material assistance you
have rendered me. I would thank you
to give me some directions respecting
the manner in which you prefer to have
plants put up, grasses, mosses and lichens
in particular. Mention the most eligible
size of specimens. I have four or five
suits of most of the plants in the list I
send you, and the specimens generally
are of such size, that each requires
a sheet of foolscap paper. Perhaps
you like them larger. Juniperus No. 3.
grows near Mariella, and I have written
to Dr Hilduth, requesting him to save it
in its different stages of growth. The tree
from which I obtained specimens
was near 20 feet in height.

I hope to hear from you soon, that
I may avail myself of the earliest
opportunity for sending you such
plants as you may request. I should
prefer American plants in exchange.

Yours truly
John L. Riddell

P.S. I omitted to mention that my list
corresponds to Eatons Manual 5th Ed.
Please mention some of the best works which
would facilitate the study of Western
plants. I should be gratified to know
when you intend publishing again.

J.L.R.]
