My dear Miss Horr:- 
Am glad to hear of your moss-class and 
that you are at work on the "local flora." If you will pardon 
my giving you unsought advice "Do keep a record and specimens 
of all local mosses !" send duplicates either to the Mew England 
J.otanl.oal Club or to v. ?. Collins, 468 Hope street. Providence, 
Rhode Island, who has a card catalogue of all Dew England mosses. 
You may and probably will, add some extensions of ranges , varia ¬ 
tions or rare species to his list l 
Sincerely yours.
