Investigations and Lectures 
In addition to routine duties, I have continued my orchid 
studies and have been occupied particularly with horti- 
cultural botany especially in its relation to the hardy woody 
plants of the Garden collections. 
I have given three of the lectures of the regular public 
courses at the Garden. My work of superintending the 
making of colored drawings for Addisonia has been con- 
tinued, and I have acted, with Dr. Barnhart, as one of the 
editors of that publication. 
Respectfully submitted, 
Geo. V. Nasu, 
Head Gardener.
