          You ask for Hypnum [instacostunsis?], I should think you
[write?] it, but I don't know it, or can't find it, if I have ever seen
it. I am troubled to read some of your specific names & yet I
may say, I write so badly, that I am rarely troubled to read any
thing I see.

On my trip to Troy, I found [Lithorpumum?], which
you sent me, & collected Podophyllum for you, tho' I fear they
will not be in very good shape, as I had no [conveniences?] for
preparing them. I got also Pinus nigra, in fine state. I made
it a geological excursion, & on my return, [?] from Troy
[nearby?] cost to this town, over hills & vallies, in a [sod/sad?] road, which
I often left for short distances. The argillite forms the bank of the
river in some planes in Troy. Gray Wacke [graywacke] lies on it about 1 1/2
mile back from the river. This rock is most evidently a kind of
aggregate. It often contains rounded masses of quartz, and as you go from
the river, the materials become rather coarse - at least , quartz in
longish pieces abounds in it, sometimes feldspar, & it looks like
porphyry. It can hardly be claystone porphyry were I well acquainted
with Clinkstone (can not you send me a piece? soon) I might know whether
it is not Clinkstone porphry in some places [added: It is however a [?]-diposite not a porphry.]. The G. Wacke extends nearly
to the Taconick range - I followed up a stream for miles, & was over
its hills, for it forms huge masses - full of seams of quartz - tends
to [break?] on this [amount?] into [?] [?] [forms?] - pretty hard 
covers a tract at least 12 miles in width, [?] [?] [?]. Occcasionally
you find a stratum of argillite, reddish, a chlorite slate. The Ta
conick range bends to the E. where I crossed it, forming a large basin.
About seven miles from the foot of it, you come to chlorite slate, tho'
hills of the Wacke extend within 4 miles of the Mt. But at about 4 miles
from the Mt. the G. Wacke croses entirely as a rock, you [see] only
[?] fragments of it in the streams - the chlorite slate [?] into
mica slate more & more, till at the Mt., you can hardly tell what
much of it is. You find however [?] mica slate, & [toliose?] slate, & some
argillite, mixed with this unnamed mixture of them all, a [?].
them all. Our common route to Troy is about 10 miles south, or
north of the plan I [?], & much less hilly. On the north route, you
find much more argillite, in Hoosack in great quantities of roofslate 
upon [?] Pittstown, is much narrower, & I [suspect?], it croses at the
north. And also East of Hudson city, it is much less abundant, If I
recollect. But on the S. rout to Troy, you [?] over a wide span
of it. The gray wacke seems to be on the micaslate or the [?]
slate connected with it, of the Taconick range. I was much surprized to
find in the basin on the west of the range, exactly the same mixture
of chlorite & quartz which comes [added: in] one part of our valley, & is [scattered?]
over it considerably. It disappears as you [?] the range W., but
shows itself abundantly soon as you get down the w. side. As a
waggon accompanied me, I brought home specimens pretty largely,
I intend now to send to our Geol. Society specimens from Hosack
Mt. to Troy. My [?] is now extended to the River. And if
Col. Gibbs is going on with any such thing in N.Y., I would
send him also. [Really?], my friend, I did not intend to give you
such a dose of rocks - tho' hard the material, I hope they will sit
cosy, & digest with facility.

The [?] [Acid?] [operates?] [?] here. I have made it for the physicians, of
excellent strength 2 drops in 24 hours have a decided effort.

I began this letter I have got [fine?] Podophyllum for you - have
found out, as I believe, Carex oligocarpa. I sent you one as C. sterilis?
but it is C. paniculata - and another , I sent you, must be C. bromoides,
if it grows on wet land as Muh. says - but Eaton says, on dry soil.
Have found too Scirpus planifolius - & today [Golium?] [aporism?] - it
curious that we have always [passed?] it. [Covrens?] stricta too, [?].
to Elliott, who says it is C. sanguinia of Walt., & has been supposed to be

P.S. to the whole. You seem to think well enough of Emmons - I find an interest in him, because I have aided in saving him from a wild & ruinous 
course in College - & he now does well considering all the [?]. In Johnson, I have no special interest, & know not much about him, only what
I told you. He thinks [some?]. But as he was going, a raw countryman into the city to
attend lectures, I thought possibly you might give him a word of advice,
which might be worthwhile to him, and good advice. This was the amount of
what I expected. I know [he/this?] would not be [vanity?] for you in any shape.
If I am badly represented by my delegates, you will yet form your own opinion _
perhaps I am a bad fellow to be represented at all.
[Say's Choncology?] & of the journal you mention. Economy is the order of the day.

I have a mineral on hand which will not ans
wer interrogations very distinctly & definitely. If
I apply a knife he will give way - the blowpipe he stands
like a salamander - an acid he [?] at, without any
[frothing?], as I can percieve. He is a [stocastical?] fellow, on
[?] - white [nearly?] - seems resolved to be a bully. Comes
from an ore bed.
