COOPERATION WITH OTHER INSTITUTIONS AND ORGANIZATIONS 
In the Annual Report for 1925 we published a list of 840 institu- 
tions with which this Garden was in active cooperation that year. 
The number has not diminished. The following for 1933 are 
mentioned to illustrate the variety and scope of this cooperation: 
1. Metropolitan Museum of Art—On May 8, the Metropolitan 
Museum of Art opened a special exhibit to illustrate the use of 
— 
plants as sources of design, the Brooklyn Botanic Garden, the 
New York Botanical Garden, the New York Public Library, and 
the New York Aquarium cooperating. This proved to be an in- 
teresting and instructive exhibit, but it entailed a very great amount 
of work. As the horticulturist has reported, the Brooklyn Bo- 
tanic Garden sent growing plants weekly or oftener to the total 
number of 570, besides 41 bunches of cut flowers and branches. 
In connection with the exhibit, the Museum held, from June 1 
to 30, an exhibition of the work of students in New York High 
Schools and Schools of Design, with studies based upon plant 
forms. Considerable use was made of the Botanic Garden planta- 
tions and library by art students in preparation for this exhibit. 
The main exhibit continued open until September 10. The esti- 
mated attendance was 90,000. 
The Merchants’ Association of New York.—Since 1922 the di- 
rector has been a member of the Committee on Plant Quarantines 
7 
and Their Administration, and on September 26, 1933, accepted 
the chairmanship of the Committee, succeeding Mr. John H. Love, 
the first chairman, who resigned. This Committee, organized in 
1922, is concerned primarily with the interests of commercial horti- 
culturists—growers, importers, wholesalers, and retailers—as af- 
fected by the administration of the Federal Plant Quarantine Law, 
known as Quarantine 37. 
Horticultural Society of New York—Since 1928, the director 
of the Garden has served as a member of the board of directors 
of the Horticultural Society of New York. 
During the year Dr. Svenson, of the Garden staff, gave a course 
of instruction, consisting of twelve sessions, under the auspices 
of the Society, and on November 13 commenced a repetition of 
this course. These courses have been largely attended and very 
popular.
