when obtainable. Identification of a single leaf is often impos- 
sible. For identification of plant diseases, representative portions 
of the part diseased should be sent. 
DOCENTRY 
To assist members and others in studying the collections, the 
services of a docent may be obtained. Arrangements should be 
made by application to the Curator of Public Instruction one week 
in advance. No parties of less than six adults will be conducted. 
This service is free of charge to members and accompanying 
friends; to others there is a charge of 50 cents per person. For 
information concerning membership in the Botanic Garden see 
pages i-i11 of this PROSPECTUS. 
EXTRA-MURAL LECTURES 
The Botanic Garden does not officially schedule members of its 
personnel for lectures or talks outside the Botanic Garden, except 
for lectures on the Garden itself or some aspect of its work. In 
such cases no fee is charged beyond traveling expenses. 
Several members of the personnel are available for lectures to 
garden clubs and other organizations on topics of general horti- 
cultural or botanical interest. A list of lecturers, with lecture 
topics and the fee charged, may be had by addressing the Curator 
of Public Instruction. 
MEETINGS OF OUTSIDE ORGANIZATIONS 
The Brooklyn Botanic Garden is glad to welcome outside or- 
ganizations wishing to hold meetings at the Garden, provided the 
general purpose of the organization is closely allied to that of the 
Botanic Garden (e.g., Botanical Groups, Garden Clubs, Nature 
Study Clubs, Conservation organizations, etc.), or that the specific 
purpose of the meeting is of mutual interest and advantage to 
the organization and the Botanic Garden. Meetings must always 
be arranged for in advance. A folder giving full details, and an 
application blank may be had by addressing The Custodian.
