Miss Elsie T. Hammond, and material should be called for at the 

 Information Booth on the ground floor. 



Special Work for the Blind. — Short courses of two or three 

 lessons will be given to blind children of elementary and junior 

 high school age. The work will be both in the greenhouses and 

 on the grounds, supplemented by special opportunities for handling 

 living materials in order to acquaint the children with the world 

 about them. This series will be given free of charge to classes 

 of not more than 15 children and not less than 7. The work will 

 be offered on school days to supplement and enrich regular class- 

 work. 



Study and Loan Material for Colleges, High Schools, and 



Junior High Schools 



Available at the Brooklyn Botanic Garden, 1941-1942 



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 ol 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 2-4433), 

 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.
