Investigations and Lectures 
I have continued my studies in horticultural botany, 
especially upon the hardy woody collections of the Garden, 
and also upon the orchids. 
T have acted with Dr. Barnhart as one of the editors of 
Addisonia, and have continued my supervision of the 
preparation of drawings for that periodical. I have given 
three lectures in the regular public courses of the Garden. 
Mr. K. R. Boynton, Head Gardener’s Assistant, had 
charge of the conservatory beds and their collections, and 
gave valuable aid in the installation of the gladiolus col- 
lection. He performed his duties up to the time of his 
induction in the service of his country in May. Mr. John 
Hartling has been acting in that capacity since that time. 
Respectfully submitted, 
EORGE V. Nass, 
Head Gardener.
