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 their classes, accompanied by 
their teachers, to come to the Botanic Garden, for lectures either 
by a teacher, or by a member of the Garden staff. 
(b) Notice of such a vist should be sent at least two days previ- 
ous to the date on which a talk is desired. These talks will be il- 
lustrated 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 1917. 
(c) 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. 
(d) The principal of any secondary or high school in Brooklyn 
may arrange also for a series of six lessons on plant culture to be 
given during the fall to a class. These lessons will be worked 
out for the most part in the greenhouse. Such a course must be 
arranged for in advance, and the class must be accompanied by 
its teacher. Adapted for pupils above the fourth grade.
