and partly obtained during 1907. Much time has been given 
by the curators to the accurate naming and classification of 
the herbarium, which is being more and more consulted by 
curators from other institutions and by students from all parts 
of the country. 
The very important collection of fungi of the herbarium 
was rearranged and installed in new herbarium cases in the 
large room at the west end of the upper floor of the museum 
building, which has hitherto been used for miscellaneous pur- 
poses, thus leaving much additional space for the collection 
of ferns, mosses and lichens, in the rooms east of the library. 
Some additional assistance in mounting and distributing speci- 
mens, obtained by gift, purchase, or exchange, which have 
accumulated in the storerooms, is very desirable during the 
coming year, in order that this material may be made avail- 
able for students and investigators. 
Library 
The use of the library by students and visitors is increasing 
as the collection becomes more complete. 592 volumes were 
added during the year, obtained by purchase and by gift, the 
total number of volumes being now 20,458, as appears in the 
report of the librarian, hereto appended. The endeavor to 
secure the older literature of botany, systematically com- 
menced two years ago, has been continued, and many im- 
portant works now difficult to obtain have been added. As 
pointed out in previous reports, this literature is continually 
becoming scarcer, owing to the largely increased number of 
libraries throughout the world, and it is therefore highly im- 
portant that the effort should be continued, and funds are de- 
sired for this purpose. During the year a contribution of 
$100, from Mr. E. S. Harkness, was credited to the Special 
Book Fund. 
The position of librarian, held by Miss Anna Murray Vail 
since 1899, became vacant in October by her resignation, 
which was received with much regret. Dr. John Hendley 
Barnhart was appointed librarian at that time.
