Herbaria in addition to those mentioned in previous reports 
now incorporated are: 
The C. L. Anderson herbarium. 
The L. T. Chamberlain herbarium. 
The Nicolas Pike herbarium. 
The local herbarium, containing only plants growing 
within one hundred miles of New York City, has been con- 
stantly added to by specimens obtained as gifts, by exchanges, 
and by the collections brought together by representatives of 
the Garden detailed to accompany the weekly field excursions 
of the Torrey Botanical Club, as well as by those selected 
from the general collections coming into the possession of the 
Garden from time to time. All the material originally 
received as the herbarium of the Torrey Botanical Club, and 
which formed the nucleus of this local collection, has been 
mounted and rearranged so as to be readily accessible. 
(6) Columbia University herbarium. For this collection 
1,294 specimens were received. From these and from 
material previously accumulated, about 700 sheets containing 
877 specimens were distributed in the cases. Imperfectly 
mounted specimens have been permanently mounted as far 
as time and assistance permitted, while such portions as were 
constantly handled in connection with the duties of members 
of the staff and the research work of the students were 
remounted or securely strapped to the sheets. Some progress 
has been made on the incorporation of the Morong collection, 
the property of Barnard College, in the general Columbia 
herbarium. 
(c) Duplicate herbarium. Specimens secured by mem- 
bers of the staff on trips of exploration, not needed for the 
permanent collection, and similar material from other sources, 
have been placed in this series, and have from time to time 
been sent to individuals or other institutions in exchange for 
desiderata. In this way over 12,200 specimens were dis-
