Dear Sir,

Immediately after writing to you in October
last (by Dr. De Camp of West Point), proposing terms for exchange
of plants an opportunity presented itself for transmitting to you
what I had on hand, which I embraced, without waiting
the expression of your pleasure on the subject, on whom, by
my plan, the labor of arrangement was to devolve.

My friend, Mr. Gray, a merchant of Detroit, has politely
offered to charge himself with the care of any thing in that
way you may have to send me. He is the bearer of this &
will stop at the N. [New] York Hotel, where I must take the 
liberty of requesting you to deposit such of the plants as
you may have in readiness. Will you furnish him with 
a copy of your Compendium? for which he has
directions to pay you.

Do you personally give much attention to entomology?
If so, you are at liberty to appropriate to your own use a
collection of insects made last season by myself at Saut Ste. Marie [Sault Sainte Marie]

Can you give me any information touching the time or the
manner in which Tanner's narrative is to be published?
