Orthoptera from South America, Katanga in the Belgian Congo, 
British India, and the Phillippines, all of which will greatly increase 
our collections when studied. 
Plants 
Owing to the illness and death, on March 14, 1921, of Mr. 
Stewardson Brown, for twenty years Curator of the Herbarium, 
the department remained for most of the year without an acting 
head, though the services of Mr. Glenn were secured in catalog- 
uing and distributing accumulated material. On October 1, 1921, 
Dr. Francis W. Pennell, formerly Associate Curator of the New 
York Botanical Garden, assumed charge, with Mr. John M. Fogg, 
Jr., as an aid. 
Little change has been possible, so far, in the housing of speci- 
mens. The rearrangement of the herbarium is progressing as 
rapidly as facilities permit,, and a further step toward making 
available for rapid reference will be the arranging of the specimens 
of each North American species in a definite sequence of countries 
and states. The North American specimens are now grouped in 
distinct covers for each species thus making the herbarium a system- 
atic index of plants; the new arrangement of sheets will make it 
also accessible to students of limited geographic areas. 
The new Curator has had little time for research but has given 
final preparation to a report on the Scrophulariaceae of Cuba. He 
has in partial completion other studies of the plants of this interest- 
ing family. A large number of specimens of Scrophulariaceae, 
from the Central Rocky Mountain States, and from Colombia, 
were brought on from New York for further study. 
Mr. Bayard Long has continued his supervision of the local 
Herbarium. He has answered many queries, determined a large 
number of specimens for various collectors, and has done critical 
study on certain genera. During the spring he continued the 
naming of Yukon plants, collected by Mr. Adolph Muller and left 
in part identified by Mr. Brown. During the summer he was 
again a member of the Gray Herbarium Expedition for the botanical 
exploration of Nova Scotia. 
Minerals 
Mr. Samuel G. Gordon who has had charge of the Mineral- 
ogical collections during the year reports that his time during the 
early part of the year was occupied with the investigation of Penn-
