PHYTOPATHOLOGICAL SURVEY OF THESTREES AND 
SHRUBS OF PROSPECT PARK AND THE BOTANIC 
GARDEN (BROOKLYN). II. REPORT OF 
THE SECOND SEASON’S WORE 
Dr, C. Stuart Gacer, Director. 
Sir: I beg leave to submit herewith my report as Resident In- 
vestigator at the Brooklyn Botanic Garden for the season of 
1917. The report deals with a continuation of the studies on 
the diseases of trees and shrubs in the Brooklyn Botanic Garden 
and Prospect Park, Brooklyn. These studies were begun in the 
summer of 1916. 
Fortunately it was possible to begin the work the present 
season on the first of April and continue it until the twelfth 
of September. The longer period-made possible much more ex- 
tended studies of the condition of the woody plants in the Park 
and the Garden. The spring months were particularly favorable 
for making careful observations of the trees for the presence of 
wood-destroying organisms. It was comparatively easy to note 
the occurrence of decayed areas before the trees had come out 
into leaf. It was also possible to secure additional collections of 
fungi, as some forms develop their fruiting stages in the spring 
months. It is to be regretted that the time could not be extended 
in the fall, for that is the season for the appearance of the repro- 
ductive structures of many fungi.
