Department propagating houses was also planted with 
shrubs. Considerable other work planned for the fall 
had to be deferred until the spring, as the unusual dry 
weather of the fall prevented an earlier undertaking of 
transplanting work. 
Investigations and Lectures 
In addition to my routine duties, I have continued my 
studies upon North American orchids, and have given much 
time to horticultural botany and to an investigation of the 
hardy woody plants of the collections and to those native 
to the Garden. 
I have given four lectures in the regular courses of public 
lectures at the Garden. I have continued my work of 
superintending the making of colored drawings for Addi- 
sonia, and have acted, with Dr. Barnhart, as one of the 
cditers of this publication. 
Respectfully submitted, 
EORGE V. Nasu, 
Head Gardener.
