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.
