932 THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 
your no less valuable avocations. But I fear—& if so it admits 
of no excuse—but an appeal to your generosity,—that I have not 
even expressed to you my warmest acknowledgements for the 
completion of your labors on my raw material of Carices—which 
has conferred undeserved honor on me—but luckily at the same 
time made my materials of some value to Botany. Upon two or 
three species I have, I think, heretofore requested your reasons for 
leaving them out—I have since when studying the book [89] 
(for as to studying this year in that of nature during the season 
of the Carices I was utterly unable to do anything) thought that 
I discovered them—especially as regards my Carex nigromargi- 
nata—I have viz. presumed that the very distinct species so called 
by me—is the one you acknowledge as C. marginata—& my 
marginata identical with vestita—which probably is the truth. 
In the occasional moments of leisure which I have had—I have 
begun for your perusal a rather extensive commentary upon your 
excellent Flora (I hope nothing has intervened to prevent your 
putting forth the second part shortly—which I most anxiously 
expect) giving you a full & explicit account of every thing in the 
northern states which I have met with, in any degree not ap- 
parently noticed in your Flora [89]—and adding as full an account 
of my southern observations—not occurring in other books—but 
my progress has been so greatly interrupted that I have not yet 
made sufficient advances to render it worth while to forward it 
to you. This winter I hope to be able to do something that way. 
My European Journey & several important accessions inde- 
pendent thereof have greatly increased my Europ. collect. of plants. 
But a most deplorable stop of any increase of American specimens 
has taken place. Do pray inform me, whether I can hope to pro- 
cure some of my desiderata thro’ your further kindness without 
encroaching too much on your time—& whether our friend Mr. 
Halsey still preserves his botanical zeal—or is in danger of falling 
into the snares of mineralogy (I cry mercy to the professors of that 
honorable Science for my impertinence). 
I should besides be extremely glad to get a number of speci- 
mens of certain New England Carices for exchange. 
I hope, my dear Sir, that these lines will elicit from you some 
sign & token of your still taking some interest in me by letting
