of August. Daily instruction was given in nature study, scout- 
craft and woodcraft. 
On October 12 I accompanied a party consisting of 150 scouts 
and Io scoutmasters from Flatbush District to Staten Island, 
when one hour’s instruction was given in nature study. 
On December 29 I conducted several members and friends of 
the Natural Science Club of Boys’ High School on a trip through 
Van Cortlandt Park, and the woods along the aqueduct beyond, 
for the purpose of studying and collecting twigs and fruits of 
trees and shrubs. 
These outside activities in nature study instruction Paha but a 
small part of the assistance to Boy Scouts, Camp Fire Girls, and 
other groups, which we are undertaking. One or more classes, 
in groups ranging from 6 to 20, have been held almost daily at 
the Garden throughout the school year. The pupils are taught, 
by outdoor study as well as indoors, to recognize and to become 
familiar with the principal trees, shrubs, and wild flowers. 
Specimens of leaves, twigs, flowers, and fruit are collected, 
mounted, and labeled. These mounts become the pupil’s own 
property, and together with the notes taken in class and on field 
trips, constitute the basis for a Garden certificate in tree study. 
In the aggregate I have personally instructed 834 individuals, 
with an attendance of 1,759.: 
The work reported above for holidays and during the summer 
months is exclusive of the regular Garden classes with which I 
assisted, and which are fully reported by Miss Shaw, curator of 
elementary instruction.

The position of librarian at the Brooklyn Botanic Garden was 
assumed by me in September,.1916. The greatest need to a new-

was a catalogue or finding-list. Therefore, every effort has been
