public popular lectures covering a wide field of botanical 
and horticultural subjects are delivered here on Saturday 
afternoons from spring to autumn; these are fully illustrated 
by means of a very extensive collection of lantern slides 
owned by the Garden which is constantly being increased. 
A noteworthy part of this collection is the series of delicately 
and accurately colored slides of flowers, fruits, trees and 
shrubs, by Mrs. Adelaide S. Van Brunt, from photographs 
made during many years by her late husband, Cornelius 
Van Brunt. 
The Horticultural Society of New York holds several of 
its monthly meetings at the Garden, using the large lecture 
hall, and also uses the basement museum hall adjacent for 
the purpose of exhibitions. 
The Torrey Botanical Club holds monthly meetings from 
October to May, on the afternoon of the last Wednesday of 
each month, in the museum building, and many of its field 
meetings on Saturday afternoons throughout the season 
are held at the Garden. 
THE LIBRARY 
The library of the Garden is located in the center of the 
upper floor of the museum building, and is available for 
consultation, by permission. It has been formed by the 
Board of Managers in order to provide for the use of 
students, all the literature of botany, horticulture and re- 
lated sciences, and is rapidly becoming one of the most 
complete collections of books and pamphlets in the world 
dealing with these subjects. It consists of a reading room, 
circular in shape, and two stack rooms opening off from it. 
The collection contains over 28,000 bound volumes. 
In addition to its own books, the library has on deposit 
many of the botanical works belonging to Columbia Uni- 
versity and the New York Academy of Sciences. 
The Cox collection of Darwiniana, named in honor of 
the late Charles Finney Cox, by whom the collection was 
made, consists of a complete set of the works of Darwin.
