Study Material for Schools 



As in former years, we have continued to supply fresh study 

 material to the schools to the extent of our facilities — twigs, 



leaves, sections of wood, flowers, protozoa, algae of various sorts, 

 fern prothallia. fern sori, etc. This part of our work has been in 

 charge of Miss Rusk. lucludiug material supplied to the schools 

 by the department of Elementary Instruction, we furnished last 

 vear io<y,oi i pupil with nub mat< i i! and is isl I in thi \ i 

 21 different high schools and annexes in Brooklyn, 12 Junior High 

 Schools, 66 elementary schools in Brooklyn, and 22 private and 

 parochial schools of Greater New York. 2,33s petri dishes were 

 filled with nutrient agar for the study of molds and bacteria. 

 This part of our work has grown so far that the average demand 

 in one month of the school vear is not much less than the total 

 annual demand si.\ years ag — nameh 358 dish Sinci th 



filling of these dishes is a time-consuming operation, it will be 

 necessary, if the demand contnnn to in reas idler to limit the 

 amount given out, or to have additional assistance. A small green- 

 house devoted entirely to the growing of materials for the schools 

 is urgently needed. 



Personal Class Work 



I have carried on as usual the courses on the Life of Plants and 

 General Botany, with weekly exercises throughout the school year. 

 The new course given for student nurses has already been men- 

 tioned (p 62) In tin -|)i' o uid fall courses on the trees and 

 shrubs of Greater Xew York, given on Saturday afternoons in 

 the various parks and woodlands of the Greater City, 36 and 6^ 

 students were registered respectively. The classes were divided 

 into two sections, each of which received instruction, alternately, 

 on succeeding Saturdays, from Miss Rusk and myself. In De- 

 cember a practical field test was given at the north end of Central 

 Park. 



As usual, in cooperation with the Brooklyn Boy Scout head- 

 quarters, I have conducted several tests for boy scouts for merit 

 badges in Forestry and Conservation.
