The Herbarium 
“ Shortly after my arrival in January the new herbarium cases 
were installed; this naturally required some re-arrangement of the 
herbarium material, and a reorganization of unmounted plants in 
storage. As a result all of our herbarium collections are now 
stored in fireproof cases. By good fortune we had the service of 
Mrs. Putz, a former worker in the Garden; thus we have during 
the past year been enabled to get several collections mounted, in-

Van Sinderen, and a large part of a set of Pringle’s plants of 
Mexico. A vast amount of material is still unavailable for use, 
due to the fact that it is unmounted. During the past winter Miss 
Burr has gone over the mosses, in order to combine the various 
collections and to remove duplicates. 
“We are now engaged in the reorganization and sorting out 
of duplicates of the extensive collection of specimens of woody 
plants made by Dr. C. K. Schneider at the Arnold Arboretum in 
1916 and 1917. 
“ During the past year herbarium material has come on an ex- 
change basis from the University of California and the United 
States National Museum. There has also been received as a gift 
from Mr. Vincent Astor the specimens of plants collected by the 
Nourmahal Expedition to the Galapagos Islands, of which I was 
the botanist. 
“In addition to some local specimens collected by Miss Rusk 
aud myself, the herbarium has received a collection of plants 
made by me during the month of August in Tennessee and Ken- 
tucky. The total number of plants in my two collections (dupli- 
cates included) 1s approximately 5,000. 
“Tn addition to routine identification of miscellaneous material, 
the writer has determined Cyperaceae, chiefly Eleocharis, for 
several institutions. 
Classes and Lectures

“During the spring of 1930, with Miss Rusk’s assistance, a 
course was given for eight afternoons on the spring vegetation of 
the New York region, and in the fall a similar series of four 
afternoon classes was held. In addition I gave a course of four
