 My Dear Prof.


 Yours of the 19th Inst. is before me
 in which my guesses have been satisfactorily answered. 
 Indeed I had made into my mind that
 the answers would be such as they were.


 You have however forgotten to say anything
 about the Fistuca [Festuca?] that I recently sent you
 for examination.  I have another task for
 you which is none lesss than to describe a
 new species of Scirpus which I discovered &
 collected yesterday not far from the high
 bluff on the North side of Tom's River &
 about two miles from the village - In its
 general appearance it resembles S. triqueter
 but differs in form texture & other particulars
 from that species - It is 3-4 feet high
 of a light green. - The spikes closely
 sessile from 6-11 in number conical and
 smaller than in S. triqueter and nearer the
 summit - the stem wing angled and [crossed out: the]
 deeply grooved or channeled equally on all (3)
 sides, a transverse or horizontal section would
 be represented by the following cut [drawing: a triangular structure with concave sides having the underlined word "bud" at each depression] The stem
 too is very soft, easily compressed - whilst the old
 species ^ [inserted: is more rigid, darker green &] [crossed out: looks none] which is only channelled on two sides
