65 
have been added during the past year to the stock being pre- 
pared to illustrate Garden lectures. Of the total number (460) 
accessioned during the past year, 218 have been colored; and 
848 negatives of botanical subjects were accessioned during 1912. 
Besides these, some illustrative material has been recently pre- 
sented to the Garden by Mr. Levison, arboriculturist of Prospect 
Park, consisting of pieces of trees of various species (to be later 
made up into a part of our loan collection for schools), and por- 
tions of diseased trunks. Also added to our material equipment 
for teaching purposes are the dried plants consisting of over a 
thousand specimens, presented to the Garden by the curator of 
public instruction. 

The research work carried on by the curator of this depart- 
ment during the past four months has concerned mainly the 
continuation of the investigations of the past several years 
having to do with various plant diseases. One paper was recently 
completed on a phase of the rust problem entitled, ‘“Intermingling 
of the perennial sporophytic and gametophytic generations in 
rusts.” This paper was prepared primarily for presentation be- 
fore the scientific meetings held during the recent holidays at 
Cleveland, and for later publication as a Contribution from the 
Garden. On December 29, in company with the director, I 
departed for Cleveland to attend the meetings of the American 
Association for the Advancement of Science and affiliated so- 
cieties, stopping on the way for a short visit to the Buffalo 
Botanic Garden. 
It is respectfully recommended that, if possible, in the fu- 
ture plantations of the Garden some space be provided for the in- 
auguration of school gardens, to be cultivated by pupils of neigh- 
boring schools. Such a development would undoubtedly prove a 
most stimulating means of arousing more general interest in 
plants and in their growth and cultivation, as well as of directing 
the attention of the community, and especially of the school 
children, to the educational activities attempted by our Garden. 
I wish to record here my thanks to Professor Bristol, of 
New York University, for the loan of a microscope for several 
months during the fall; as well as to the authorities of the
