dent for two years, and Mr. Kaiser, the Curator of the 
moss-herbarium, has assisted in answering the questions 
that have been referred to us for decision. 
Acting as Secretary for the Stokes’ Fund and the Wild 
Flower Preservation Society I have answered letters, dis- 
tributed literature and arranged for the cooperation of 
various Garden Clubs and other associations, including the 
Boy Scouts, Torrey Botanical Club, schools, etc. The 
Audubon Societies also are cooperating, in order to secure 
native fruits for the birds. Owing to disturbed war con- 
ditions and the added cost of all color work, no illustrations 
of our native wild flowers needing protection have been 
printed, but four new ones are ready to be printed. 
During the year a general supervision of the lantern 
slide collection was entrusted to me and 196 colored and 
207 uncolored slides were added to the collection, including 
Dr. Pennell’s Colombian and Dr. Rose’s Ecuador slides, 
as well as Mr. Parson’s slides of the school garden work and 
the photographs of the soldier students at work. Colored 
records were also made of some of the exceptionally fine 
dahlias from the west border, and a small set of some of 
our rarest native orchids were also added. Several appli- 
cations for the loan of slides have been received but so 
far no provision has been made for this purpose. 
Respectfully submitted, 
Exizapetu G. Britton, 
Honorary Curator of Mosses.
