280 THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 
especially of the S. American species.—Have you any of the 
Surinam plants left, that you could spare him? He is much in- 
_terested in S. American Botany. Rafinesque’s proposal for the 
Duplicates of Baldwin’s collection was a strange one! You of 
course declined it. 
Did I tell you that I had made an engagement with Dr. Gray 
(of Utica), to aid me in my botanical & chemical labours? He 
lives in my house, & is now working daily at my herbarium. My 
whole collection will soon be arranged according to the Natural 
method, & in the spring (D.V.) I shall attack with zeal, my Flora 
Synopsis of North American plants [92]. Dr. G. will devote part 
of his time to his own concerns (according to our agreement), 
& has made arrangements for publishing collections of dried plants 
of the more difficult genera & families:—such as Gramineae, 
Cyperaceae, Aster, Musci, &c. He hopes to publish the 1st No. 
of his N. Am. grasses in the Spring & the 1st No. of his N. Amer. 
Mosses about the same time. The price will be $5. for 100 sp. 
neatly fastened on white paper, with printed title page, index & 
labels—with a handsome portfolio. The specimens placed loose 
[on] herbarium papers, with printed labels—but without the 
portfolios will be sold at $4 pr. 100.—When you write to your 
German friends please give them this information & cause it 
to be printed in some botanical periodical or magazine in Germany. 
Dr. Gray will spend a month or two every season in collecting 
specimens from the most interesting localities that are not too 
remote. 
Have you seen the 6th edn. of Eaton’s Manual of Botany [20]? 
I have not examined it—nor indeed have I scarcely seen more 
than the covers of the book. I began to read the preface in a book- 
store the other day, & it seemed to be a most remarkable per- 
formance,—but I was interrupted before I had finished the first 
page. Dr. Lewis Beck’s new Work [7] is a pretty good compila- 
tion—but it does not settle many of our difficult plants. 
Have you the 6th No. of Hooker’s Fl. Bor. Amer. [34]? It goes 
partly through the Compositae. The Dr. hoped to have com- 
pleted the Ist. Vol with the 6th No. but he finds it necessary to add 
“a 7th No. The whole work (excluding all the Crypts. but the 
ferns) will make two volumes of 13 numbers.—It is a charming
