NOTE. — It is suggested that when such talks as 1, 6, 10 and 11 are desired 
that the groups be made so that the individual child may asssist in the lesson. 
If no more than fifty children are in the section, this may be divided into two 
small groups, and each child will be able to work and take away with him to his 
classroom and home the intimate knowledge thus gained. The above talks will 
be given only at the Brooklyn Botanic Garden, where the greenhouses, 
economic plants and the grounds make it possible to acquaint the children 
with the living material. Principals and teachers should make appointments for 
classes at least one week in advance. These talks are listed by grades to correlate 
with the city syllabus in nature study and geography. Any talk will be given to 
any class of either public or private schools, regardless of this grading.
