iris garden. The rear half of each herbaceous border, with 
occasional areas in front for the smaller species, will be 
allotted to this flower. In front of the irises it is planned 
to grow bulbs, followed by annuals and greenhouse plants. 
Considerable of the planting of deciduous shrubs has 
already been accomplished. In the border along the west 
path, 1,550 tulips have been planted, given by John 
Scheepers & Company, Inc., and in the border along the 
path extending to the east, 1,920 tulips were installed. This 
is only sufficient to plant a part of the area here intended 
for bulbs. 
In the various decorative plantations, 31,128 bulbs have 
been planted, 8,374 of these being the gift of John Scheepers 
& Company, Inc. These were distributed as follows: beds 
in the conservatory court, 12,900; fountain at the foot of 
the museum approach, 2,200; iris garden, 3,470; for re- 
placement in groups which were becoming depleted, 5,576; 
bed in conservatory plaza, range 1, 2,900; the remainder 
in various groups of shrubbery. 
Investigations and Lectures 
In addition to routine duties, I have continued my studies 
upon the orchids for North American Flora, and have given 
much time to horticultural botany. 
I have also given four lectures in the regular courses of 
public lectures at the Garden, and have superintended 
the making of colored drawings for Addisonia. 
Respectfully submitted, 
EORGE V. Nasu, 
Head Gardener.
