Ninety-five volumes of periodicals have been collated and made 
ready for the binder. Eighty-seven pamphlets have been put into 
pamphlet binders. 
The collection of photographic negatives and lantern slides has 
been cataloged. The collection numbers 1059 negatives and 946 
lantern slides, colored and uncolored. The entries have been 
made on cards printed with a special form designed at the Garden 
for this purpose. Twelve hundred (1,200) cards have.been 
written and are ready to be filed. 
The set of index cards of Agricultural Experiment Station lit- 
erature numbers 5,693, and the filing of these cards has been 
started. The books most in demand for the work of the herbar- 
ium have been deposited in that room, in order to facilitate the 
work, and the classification and cataloging have been started. 
During the summer, I visited the New York Botanical Garden 
Library and spent some time at the Missouri Botanical Garden 
Library, with a view of devising a scheme for the classification of 
our library. I also consulted the various classifications of botanic 
literature that have been published and several that were sub- 
mitted to us in manuscript. 
Feeling convinced that the important factor in the arrange- 
ment of such a library is simplicity, and that the classification of 
the books need not be an index to the science, I drew up a classi- 
fication and submitted a copy to each member of the Garden staff. 
Some time afterward, we met to discuss the classification and 
after altering a few details, it was adopted. 
The following is an outline of the main topics on which the 
classification is based:
