livered on Saturday afternoons in the museum building 
from April 28 to October 20; instruction by docents has 
been somewhat expanded, this being made available for 
parties of both children and adults every week-day after- 
noon. Nature-study lectures were delivered to high 
school students. The laboratories and experimental 
grounds and greenhouses have been used by advanced 
students from colleges and universities. Increased use of 
the library has been made by visiting students and inves- 
tigators. The amount of information given out by mail is 
increasing, requiring much of the time of members of the 
staff. Botanical exploration under the auspices of the 
Garden was accomplished in Argentina, in Colombia, in 
South Carolina, and in Florida. In cooperation with the 
Horticultural Society of New York, public exhibitions of 
plants and flowers were given monthly during the summer, 
and over 5,000 rose bushes were planted in the new rose 
garden. 
In cooperation with the International Children’s School 
Farm League, instruction in gardening was organized in 
April and has since been continued; land for the purpose 
was prepared on the eastern side of the grounds south of 
the nurseries, rooms for teaching purposes were fitted up 
in the mansion, and greenhouse instruction has been given 
in one of the propagating houses. All courses are available 
for students during 1918. 
Publications during 1917 include Volume 18 of the 
Journal, Nos. 31 and 35 of the Bulletin, Volume 9 of 
Mycologia, 3 parts of North American Flora, 11 numbers of 
Contributions, and the second volume of Addtsonia.
