BUILDINGS: The laboratory building and conservatories are 
located on the eastern side of the Garden, near Washington Ave- 
nue. Entrance to both structures may be had from either Wash- 
ington Avenue or through the Garden from Flatbush Avenue or 
from Eastern Parkway. 
USE OF BUILDINGS: Teachers with classes may arrange in 
advance to hold sessions in the lecture room in the laboratory 
building, or in the class room in the conservatories. There is a 
black-board in the lecture room. 
EQUIPMENT FOR THE USE OF TEACHERS 
LIBRARY: The library is not a circulating library, but is open 
free for reference every day in the week, except Sundays and holi- 
days. Members of the garden staff will, whenever possible, be 
glad to give any information concerning botanical literature. 
Over 65 periodicals on botany or closely related subjects are 
currently received. 
HERBARIUM: The Garden herbarium contains over 104,000 
specimens, including spermatophytes and cryptogams, and may 
be freely consulted by arranging with the curator in charge. 
LANTERN SLIDES: The Garden collection of lantern slides 
numbers at present about 1500, but is constantly growing. These 
slides cannot be loaned for use outside the Garden, but may be 
used by teachers holding class exercises in our lecture room, 
which is equipped with a modern lantern for both transparent 
and opaque projection. 
PLANT MATERIAL: The Garden cannot undertake to supply 
living plant material in large quantities for class use, but will be 
glad to receive requests at anytime, for material in small quantities, 
and these requests will be met to the full extent of our ability to 
do so. Teachers who wish to grow such material as fern prothalli 
and seedlings, or to collect fresh water algae from our lake and 
brook, may obtain permission to do so on application to the 
curator of public instruction. 
LABORATORY APPARATUS: Teachers wishing to set up 
experiments in the conservatories or elsewhere will be supplied 
with simple apparatus, such as beakers, test-tubes, flasks, Petri- 
dishes, etc. Balances for weighing are also available. 
INSTRUCTOR: When notice is given in advance an instructor 
will conduct class exercises on subjects, supplementary to the 
school work, not regularly included in the high school course, 
such as plant propagation, or other applied phases of botany. 
DOCENTRY: Arrangements may be made for the services of a 
teaching guide to conduct classes to any section of the plantations 
or for field lessons in the Garden on any special topic. No special 
permission or arrangement, of course, is required for teachers 
who wish at any time to conduct their own classes through the 
Garden.
