REPORT OF THE ASSISTANT DIRECTOR 
Dr. N. L. Brrrron, Drrector-1n-CuiEr. 
Sir: I have the honor to submit the following report for 
the year 1914. 
The details of maintenance are chiefly outlined in the 
various reports to follow. I submit herewith for your 
files the weekly reports of the Superintendent of Buildings 
and Grounds, which show an unusual amount of work 
accomplished during the year by our laborers. 
The season has been remarkable in many ways. ‘The 
spring was late and cool; the summer wet, but fortunately 
without floods or serious windstorms; the autumn very 
dry, ending with bountiful rains before freezing weather; 
and the closing days of the year the coldest on record. 
Fewer mosquitoes and elm beetles appeared than ever 
before, probably owing to unusual weather conditions. 
The hickory bark beetle and the hemlock borer have ap- 
parently been kept in check by our destructive and pre- 
ventive measures and by the work of woodpeckers and other 
natural enemies. The brood of white grubs which des- 
troyed some of our lawns two years ago matured early in 
the season and escaped in the adult form. The army worm, 
new to the present generation in this vicinity, appeared on 
our borders but did no damage within our boundaries.
