          advantage you I will willingly endeavor to give it. I will willingly
forward it in an way in my power. I have also a Mineral which
I intend sending you by this opportunity as I am no mineralogist I
cannot tell whether it is of any importance or not. So far as I
can learn only a smallpiece of it has come into my possession.
Some 3 or 4 years ago it was found in the center of a large nook which
was blown at Schaghticoke point for the purpose of receiving 
the [crossed out:?] axle of a water wheel of a factory. A considerable quantity
of [rock chrystals?] as they were called were also found along with this
but I never have been able to find any of them. This is the  history as 
I learned it, whether it is correct or not I am unable to determine.
If it is worthy a place in your Lyceum you may present it, if
not return it or dispose of it as you think proper. At all events 
let me know your opinion respecting it. I send this by the
Rev'd Alexander [Bellious?]. Perhaps he may call upon you,
if you find it convenient write by him. He probably will
remain in New York a week or two. If I think of anything 
before sealing this I will add it as a P.S.

I remain your sincere friend

grasses which were not named in your last, inform me, as I intend
studying the grasses this summer I wish all possible information
aspecting them. I also find them considerably efficient and also 
interesting. I know many of the Carices were not far enough around
to be accurately determined but I did not revisit the places where 
they were collected when they were farther around & of course was
