To visiting college classes in geology and physiography the Bo- 
tanic Garden offers interesting material for a study of glaciation. 
Notable features are a portion of the Harbor Hill terminal moraine 
(Boulder Hill), the morainal pond (the “Lake’’), the labeled glacial 
boulders, and the Flatbush outwash plain. See Guide No. 7, 
“The Story of our Boulders: Glacial Geology of the Brooklyn bo- 
tanic Garden.” 
Talks at Secondary Schools and Colleges.—Informal illus- 
trated talks on various subjects of an advanced botanical nature 
are always gladly given at Secondary Schools and Colleges by 
members of the staff. Arrangements for such talks should he 
made with the Curator of Public Instruction. 
School Classes at the Garden.*—-Public or private schools, 
both elementary and secondary, may arrange for classes to come 
to the Botanic Garden for illustrated lectures by a member of the 
Garden staff, or for guided tours of instruction through the con- 
servatories and outdoor plantations. 
Visiting classes must be accompanied by their teachers, and 
notice of such visits should be sent at least one week in advance. 
Blank forms for this purpose are provided by the Garden. — Lists 
of talks and trips offered will be sent on request: for Junior High 
and Elementary Schools address the Curator of Elementary In- 
struction; for High Schools, the Curator of Public Instruction. 
Seeds for School and Home Planting.—Penny packets of 
flower and vegetable seeds are put up by the Botanic Garden for 
children’s use. In the early spring, lists of these seeds, order 
blanks for teachers and pupils, and other information may be 
secured on application to the Curator of Elementary Instruction. 
Demonstration Experiments.—Teachers may arrange to 
have various physiological experiments or demonstrations con- 
ducted at the Garden for the benefit of their classes. Communica- 
tions in regard to these matters should be addressed to the Curator 
of Public Instruction. 

* Visits to Botanic Gardens and Museums by Public School classes have 
been generally discontinued by the Board of Education for the duration of 
the war. Visits by classes from Private Schools and Colleges will be sched- 
uled in harmony with existing regulations.
