          Albany. Aug. 15th 1820

Dear friend,

Now let us have a brisk correspondence
for a few weeks, while I remain at Albany.
I received yours of the 3d [?] yesterday when I was
at Troy. Write to me at Albany until the
10th day of next month.

I am good for nothing, excepting geology, only
for communicating to others what I receive from
you &c.[etc.]. In this I greatly excel. I study every avenue
to the minds of the ignorant. I have picked
up crossed out: a few][added: two] things, which I cannot name. These I
will send you soon. I will "keep an eye out" as you
say; but I do not believe I find any thing new 
to you

Would not it be best for you to give the Crptogamia
of our district in full, excepting Fungi, and
to give the most common or the most clearly of
them? I believe fungi are much more abundant
at the south than the north.

My Manual, 2d. Ed. is not out entirely.
We print another edition this fall, or the
beginning of winter. I intend to give synonyms
and authorities in a fine type on the margins,
in the manner of Cleaveland' mineralogy. I want
a list of the errors you have detected and your 
additional trash.

I am now printing a little book of Exercises 
in Botany, price to be 50 cents. This
you cannot advise me about. It grew out of the
necessities known only to teachers. County people
