DIRECTOR 
SUBMITTED TO THE BOARD OF TRUSTEES OF THE MISSOURI 
BOTANICAL GARDEN, JANUARY 13, 1915 
Gentlemen: 
I have the honor to submit herewith the Twenty-Sixth 
_ Annual Report of the Director.

eases of structural timbers, illustrating the more common 
types found on wood. Various kinds of treated timbers, 
showing both freshly treated material and timbers show-

of the Garden. The new residence was completed and
