1935 more than 1,000,000 packets were distributed. In the early 
spring, lists of these seeds, order blanks for teachers and pupils, 
and other information may be secured on application to the Curator 
of Elementary Instruction. 
E. Conferences.—Conferences may be arranged by teachers 
and principals for the discussion of problems in connection with 
gardening and nature study. Appointments must be made in ad- 
vance. Address the Curator of Elementary Instruction. 
F. Study and Loan Material.—To the extent of its facilities, 
the Botanic Garden will provide, on request, various plants and 
plant parts for study; also certain protozoa and sterilized nutrient 
agar. 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 supphed or loaned. This charge will be made 
only for material furnished to junior high schools, high schools, 
and colleges. As far as possible, material will continue to be 
supplied gratis to elementary schools in case one or more of their 
teachers are members of regular Botanic Garden classes. A Price 
List of the various materials furnished will be mailed on request. 
Requests for high school and college material should be made 
by mail or telephone (PRospect 9-6173), at least a day in ad- 
vance, to the School Service Assistant. Itequests for elementary 
school material should be made to Miss [Elsie T. Hammond, and 
should be called for at the Information Booth on the ground floor. 
High school and college material should be called for at Room 327.
