constantly received. These are often as important and should 
be as easily accessible at all times as bound volumes, but owing 
to their unprotected condition, they may be easily destroyed by 
constant use. A system of caring for these has been adopted. 
This consists of binding each one separately in a pamphlet 
binder and treating it as a bound volume. The Gaylord pamphlet 
binder seemed best to serve our purpose. This is a heavy press- 
board binder, faced on the edges with cloth. The pamphlet is 
securely fastened to it by a folded gummed strip, and when 
considered necessary, is further strengthened by the use of wire 
staples, especially designed for the purpose. ‘The design of the 
- library book-plate, printed on the outside cover of the binder, 
makes it additionally attractive, and insures the ready identifica- 
tion of misplaced pamphlets. Various sizes of binders are pro- 
vided as required, and different combinations of colors have 
been chosen for the various classes of publications to be bound 
in them, as follows: for experiment station publications, tan 
pressboard with brown binding; for miscellaneous Government 
publications, tan pressboard with tan binding; for separate re- 
prints, green pressboard with red binding; for other pamphlets, 
green pressboard with green binding. This work of binding 
has been commenced this year and will continue from year to 
year as the library grows. 
The shelving facilities have been somewhat increased by the 
addition of thirty-five “elastic” book units, which have been 
temporarily pressed into service for library use, but even this 
additional equipment does not permit the shelving of all books, 
and many of them, not at present urgently needed in the con- 
duct of the work of the Garden, will remain in storage until 
the completion of our own building. 
As will be seen in the summary on page 70, the growth of 
the library during these two years of its existence has been 
quite significant. 
We have completed to date the following serial publications : 
Rhodora, which has also been bound; Bulletin of the Torrey 
Botanical Club; Journal of Biological Chemistry; The American 
Botanist; The Ohio Naturalist; and Leaflets, by E. L. Greene.
