the distinguished British bryologist, which was purchased by 
contributions of money made by Messrs D. O. Mills, Andrew 
Carnegie, J. Pierpont Morgan, James W. Ford, G. W. Per- 
kins, and C. F. Cox; by securing this valuable herbarium, 
the collections of mosses at the Garden are now probably as 
complete as any in existence, and they will therefore be of 
great assistance to all American students of these plants. 
The herbarium of lichens, accumulated by Dr. H. E. Hasse, 
and presented by Mr. John I. Kane, has materially strength- 
ened our collections of these interesting plants. 
Details of the work in this department will be found in the 
report of the Head Curator. 
Contributions of money for the increase of the museum 
and herbarium collections have been received from friends 
of the Garden and credited to the Museum and Herbarium 
Fund as follows:

Library 
As shown by the report of the Librarian hereto appended, 
the number of volumes added during the year was 2,733 and 
the library now contains 20,362 volumes. The collection is 
rapidly becoming one of the most perfect of its kind, due to 
the policy adopted last year of empowering the firm of H. 
Georg & Company of Geneva, Switzerland, to obtain for the 
garden all of the older literature of botany, not already 
secured, which is offered for sale in Europe. In this way, 
many volumes have been secured which could not have been 
obtained by the ordinary methods of purchasing from the
