Use of the Garden by the Public and Private Schools continues 
to increase. Seven hundred and seventy-five classes, accompanied 
by their teachers, with an enrollment of over 53,000, visited the 
Garden for instruction during 1923. Of the 365 days in the year 
approximately 170 are eliminated from the school calendar by 
vacations, holidays, Saturdays, and Sundays, leaving only about 
195 school days when classes might come from the schools. If 
we make further deductions for the first few days of each school 
term and the days devoted to examinations (about 35), there re- 
main only about 160 days when classes might be expected. On 
this basis the average attendance during the year has been nearly 
five classes or over 330 pupils a day. 
These classes came from 89 (over 46 per cent.) of the Public 
Schools of the Borough. Classes also came from many parochial 
and other private schools. The service of the Garden to the 
City schools now extends from Barren Island to the East River, 
and from Bay Ridge to and into the Borough of Queens. Several 
classes have come to the Garden from Manhattan schools, and 
teachers have been registered in our classes from every borough 
in the City except Richmond (Staten Island). 
At present over go per cent. of the elementary sino: of 
Brooklyn are availing themselves, in some form or another, of 
the educational advantages offered by the Garden. From the 
above statistics one can readily appreciate the extent to which 
public education in Brooklyn would be impoverished if deprived 
of the cooperation of the Brooklyn Botanic Garden. 
Teachers Conferences—But the above paragraphs do not tell 
the whole story. During the year, 391 public school teachers have 
sought conferences with members of the Botanic Garden staff 
concerning illustrative materials, lesson planning in nature study, 
geography, and botany, and other problems inv olving the instruc- 
tion of over 146,000 pupils, whose work has been greatly enriched 
as a result of these conferences.

classes from the schools, our own classes have had an enrollment 
of nearly 4,000 adults and children, with an attendance of nearly 
26,000 as compared to nearly 20,000 in 1922—an increase of 
about 30 per cent.
