24 MISSODRI BOTANICAL GARDEN. 
Through the college year. Miss Mulford was occupied at 
the Garden with a study of the United States representa- 
tives of the genus Agave, on which she presented a thesis 
for the Doctor's degree, which she received from Washing- 
ton University at its last commencement. 
Since the opening of the present college year, one can- 
didate for the Master's degree has been devoting two 
mornings a week to a study, at the Garden, of trees and 
shrubs in their winter condition, under my instruction, in 
addition to taking several of the undergraduate electives in 
botany at the University. 
Very respectfully, 
Wm. Trelease, 
Director.
