companied 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. Blank forms are 
provided by the Garden for this purpose. 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 1926-7. 
(c) The Garden equipment, including greenhouses, plant mate- 
rial, lecture rooms, lantern and slides, is at the disposal of teachers 
who desire to instruct their own classes at the Garden. Arrange- 
ments must be made in advance so that such work will not conflict 
with other classes and lectures. For High School classes address 
Curator of Public Instruction. For Junior High and Elementary 
School classes address Curator of Elementary Instruction. 
(d) The principal of any elementary or high school in Brooklyn 
may arrange also for a series of six lessons on plant culture to be 
given during the fall or spring 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 accom-

grade. 
C. Seeds for School and Home Planting.—Penny packets of 
seeds are put up by the Botanic Garden for children’s use. In

secured on application to the Curator of Elementary Instruction. 
D. Conferences.—Conferences may be arranged by teachers 
and principals for the discussion of problems in connection with 
gardening and nature study. The last Monday afternoon of each 
month will be reserved for such conferences: appointments must 
be made in advance. Address Miss Ellen Eddy Shaw. 
E. Study and Loan Material.—To the extent of its facilities, 
the Garden will provide, on request, various algae and protozoa, 
as well as living plants, leaves and twigs, or other plant parts for 
study. Where containers are necessary, as in the case of the 
algae and protozoa, they must be furnished by the school. Petri 
dishes will, on request, be filled with sterilized nutrient agar ready 
for use in the study of bacteria and molds. They should be
