COOPERATION WITH LocaL SCHOOLS 
1. Talks at Schools.—The principals of public or private 
schools may arrange to have lantern talks given at the schools on 
various topics related to nature study, such as garden work with 
children, tree planting, and Arbor Day. If an illustrated lecture 
is desired, the lantern and operator must be provided by the 
school, but slides will be furnished by the Botanic Garden. Ad- 
dress the Curator of Elementary Instruction for list of talks and 
for appointments. 
2. School Classes at the Garden.—(a) Schools not provided 
with a stereopticon may arrange for classes, accompanied by their 
teachers, to come to the Botanic Garden, for lectures either by the 
teacher, or by a member of the Garden Staff. 
(b) Notice of such a visit should be sent at least one week 
previous to the date on which a talk is desired. These talks will 
be illustrated by lantern slides, and by the conservatory collection 
of useful plants from the tropics and subtropics. Spring and fall 
announcements of topics will be issued during 1910. 
) The Garden equipment, including greenhouse, plant ma- 
terial, lecture room, lantern, and slides is at the disposal of 
teachers who desire to instruct their own classes at the Garden. 
Arrangements must be made in advance with the Curator of 
Elementary Instruction, so that such work will not conflict with 
regular classes and lectures.
