schools. Requests from Elementary Schools should be made to 
Miss Elsie T. Hammond, and material should be called for at the 
Information Booth on the ground floor. 
Study and Loan Material for Colleges, High Schools, and 
Junior High Schools 
Available at the Brooklyn Botanic Garden, 1942-1943 
The Botanic Garden is able to supply various plants and plant 
parts for study ; certain protozoa; sterilized nutrient agar ; and also 
material and mounts for exhibit purposes. When containers are 
necessary, as in the case of agar, algae, and protozoa, they must 
be furnished by the school. 
In the past, the Garden has offered this service gratis, but both 
on account of the increasing demand and because of the decrease 
in appropriations, it has become necessary to make a small charge 
for the material supplied or loaned. A Price List of the various 
materials furnished will be mailed on request. 
Requests should be made by mail or telephone (Main 24433), 
at least one day in advance, to Miss Jeanne P. Walther, and the 
material should be called for at Room 204. Unpotted material 
will be mailed if the school pays postage.
