formal instruction to classes in both elementary and advanced 
courses, and opportunities will be freely offered to teachers in 
local schools to use the Garden collections, laboratories, class- 

rooms, library, conservatories and plantations in any way that 
may facilitate their work. ‘To this end, two ample classrooms 
and an elementary laboratory are included in the plans for the 
laboratory building, while one of the houses of the conserva- 
tories, adjacerit to the laboratory building, will be devoted pri- 
marily to this work. So far as the resources of the Garden will 
permit, study material will be freely supplied to schools for class 
use. 
In addition to the work of formal instruction, it is the 
purpose of the Garden authorities to offer every possible facility 
for investigation. In addition to the elementary laboratory, the 
plans of the building include three laboratories for advanced 
work, a physiological dark-room, a constant temperature room, 
and, in addition to these, ten private research rooms, for the use 
of registered investigators. One of the conservatory houses is 
designed primarily for research work, and a portion of the 
grounds is assigned as an experimental garden, to facilitate work 
in experimental evolution and plant breeding. 
On account of the ample facilities in systematic botany al- 
ready offered elsewhere in Greater New York, no special effort 
will be made for the present to develop this phase of the science, 
except in so far as is necessary in the administration of our liv- 
ing collections, and as a natural outgrowth of the work of the 
Garden as a whole. Emphasis will be placed largely on the 
experimental phases of botany, while a herbarium will be de- 
veloped chiefly with reference to the local flora, the collections 
of living plants, and the needs and activities of the other de- 
partments of the Garden. 
he departmental organization of the Garden and the classi- 
fication of the plantations have already been given in detail in 
the Recorp for April, 1912.
