My dear Mr. Collins; 
I would be very glad to examine your collec¬ 
tion of hepatics and to send you a report on 
them,; Quite a number of additions have been 
made to the New England flora since the publi¬ 
cation of my Preliminary hist in 1903, and I am 
in hopes that still further additions will come 
to light,' I hope there will be some Rhode Is¬ 
land specimens among those you send. 
The catalogue of Sphagnaoeae by Mr. Andrews 
is very welcome. His knowledge of bryophyt.es, 
both mosses and hepatics, seems to be thorough 
ana t,ru3twort|iyj and it was fortunate that. he 
was willing to undertake the study of a group 
which most students are anxious to avoid. How 
is your own catalogue of New England mosses pro¬ 
gressing ? 
Very truly yours,
