Maps AND LIsTs 
It will require another season to complete the new condensed 
form of maps of trees and shrubs which include the main syste- 
matic section, the lilac triangle, the ornamental Malus and Prunus 
section, and the nursery. On the left hand sheet facing each map 
are three typewritten lists: 
1. Grounds, that is, plants on the map of the grounds, alpha- 
betically arranged, giving year of accession and source. 
2. Nursery, additional species and varieties not yet on the 
grounds. 
3. Desiderata, that is, additional plants in the various groups that 
we wish to obtain. 
IRIs 
The report of Dr. George M. Reed, in charge of Jris plantations, 
will be found in the statistical report attached hereto, page 88. 
COURSES 
During the spring I gave ten outdoor lessons on ‘Ornamental 
Shrubs,” studying about two hundred species and varieties at the 
time of flowering, continued with ten lessons in the fall, studying 
foliage and fruits. 
Visits TO OTHER INSTITUTIONS 
During the spring and again in the fall, I visited the Arnold 
Arboretum, taking notes comparing their collections with ours. 
I also collected seeds, and consulted with Mr. Alfred Rehder and 
others. During August I visited Cornell University, consulting 
with Dr. K. M. Wiegand and Dr. A. J. Eames. 
LABELS 
Numerous labels have been put on the grounds, comparatively 
few trees and shrubs now remaining unlabeled. 
In the case of the woody plants the labels have been simplified 
by omitting the hook on the lower buried end of the iron upright. 
The buried end was originally turned at right angles to the upright 
to make it difficult for ‘“vandals”’ to pull up the labels. This 
precaution has now become unnecessary.
