 Dear Sir, 


                                       I hope Sir you will excuse me for not 
 writing to you ere this, The Plants I designed sending to 
 you. I kept in my possession until a few days before
 I received your letter, which was near the period the navigation
 closed. At that time I supposed that my letter had 
 not reached you, and having an opportunity, I sent this
 plants to Dr. Darlington of West Chester. 


 The Dr. has ever been a valuable friend to me, in aiding 
 me in the different departments of Natural Science.
 But he did not give me any satisfaction in relation to 
 a number of my difficult carices, grasses, & Salices. I am
 sensible that your Monograph of N. American Cyperaceae
 would afford me much assistance, and I have been long 
 anxious to have a copy of it in my possession. You think you could
 spare me a copy. One left as Lea & Blanchards, Corner
 of 4th and Chestnut St. Philadelphia, Directed to me, in the 
 care of B. Pyle, before the first of June will reach me. 


 I designed visiting New York this Spring, but I now
 find it impossible and I must abandon the idea until a 
 future period. I can however send you Plants to Philadelphia 
 at any time during the summer.


 The Flora of North America is an invaluable work, and 
 permit me to say, that my own insufficiency is all that prevents
 me from satisfactorily determining every species that I have met
 with, that falls within the limits of work in my possession.
 I hope it will be finished in the same style is has been 
 thus far progressed, only that the number of subscribers
 will increase, which will be the case when it is known.
 My friend Dr. Mead of Illinois, an excellent Botanist, (and a 
 Millerite) says in his last letter to me, he has recieved
 six numbers of the work, which for many reasons far exceeds
 in point of utility all other works he has ever seen, and he
 would like to have seen it finished! 


 I will now proceed to give you a list of all the plants
 that I recollect having met with peculiar to this section
 of country, but not having my journal at hand I 
 cannot recollect all that I have met with. Any information
 in my possession relative to any of the plants will be communicated
 to you with the greatest of pleasure. 


 A complete set of Specimen of the Carices between 40 & 50
 different species, and the Salices 13 species, of this County
 are in the possession of Dr. Darlington, the Carices I
 have determined are
