REPORT OF THE ASSISTANT DIRECTOR 
Dr. N. L. Brirron, Drrector-1n-Culer. 
Sir: I have the honor to submit the following report for 
the year 1917. 
The weekly reports of the Superintendent are submitted 
herewith for your files to supplement the annual reports 
to follow, which include only the more important details 
of maintenance for the year. 
The season of 1917 was remarkable for its cold, wet 
spring, being two weeks or more later than the average. 
There were no floods of any consequence, but a rather 
violent storm occurred in October which uprooted 27 trees.
