carefully mounted plants to the Hew England Botanical Club, where it is 
a valuable addition to- the Club Herbarium. 
At Brown as part of his graduate work he identified a large portion 
of the mosses collected"by Prof. J. Franklin Collins on the Mt.Katahdin 
trip which several New England Botanical Club members undertook in 1900. 
This interest continued and steadily grew-till he became an acknowledged 
authority on the subject. It has been Mr. Chamberlain’s plan to give up 
teaching in a year or two, so as to devote himself entirely to scientific 
study, and he had thought seriously of doing so last fall. He had 
collected a remarkably fine and complete library of bryological lore, as 
well as a very large moss herbarium, and he was looking forward to years 
of study and classification. 
For over ten years he has been the efficient Secretary-Treasurer of 
the Sullivant Moss Society and Business Manager of their publication, The 
Bryologist. He corresponded with most of the members here and abroad, and 
worked constantly and faithfully for its interests, often paying minor 
deficits from his own pocket. Such services as his can not be paid for, 
it comes from a desire to help others. 
This spirit of helpfulness and service was the keynote of Mr.Chamber¬ 
lain’s character. Although he tried to keep himself.in the background, it 
was his underlying motive in life. He was successful in heIpin others, too, 
in more ways than can be given here. Relatives, friends, students, and even 
casual acquaintances, all remember his characteristic ways of speech and 
writing, and the spirit that was in the man. 
Mr. Chamberlain wrote several articles for Rhodora in its early days, and 
has been a frequent contributor to the pages of Fne Bryologist. As a letter- 
writer he was unexcelled, putting a great deal of himself into what he wrote, 
and gifted there, as elsewhere, with a strong sense of humor.
