50 Report of the President 



Thus, in four years, the number of schools has trebled, while 

 the circulation of slides has increased more than sixfold. 

 More important, however, is the increase in number of times 

 that an individual school borrowed slides. The record goes to 

 P. S. No. 168 Manhattan, of which Miss Cecilia A. Francis is 

 Principal, which has been supplied ninety-four times during 

 the year. Other schools that have records of borrowing more 

 than twenty-five times are: 



New York Training School for Teachers 40 times 



P. S. No. 171 Manhattan 47 



P. S. No. 23 Bronx 29 



P.S.No. 42 " 52 



P.S.No. so " 31 



P. S. No. 126 Brooklyn 46 



P.S.N0.149 " 38 



Bay Ridge High School, Brooklyn 26 



The significance of these statistics is that this service is ex- 

 tended to the schools of all boroughs and that the teachers are 

 systematically using these valuable aids to instruction. 



Our experience of previous years has proved that the slides 

 that are arranged in complete lectures are more useful to the 

 teachers than the general selection from the Museum file. So 

 great has been the demand for several subjects that it has been 

 necessary to triplicate some of the sets. During the year, six 

 new sets have been added to the loan series, making a total of 

 twenty sets in all. No. 15, "Implements of Modern Warfare — 

 The Aeroplane," No. 16, "Implements of Modern Warfare — 

 The Submarine," No. 19, "Our National Heroes," and No. 20, 

 "The State Reservation at Saratoga Springs," were prepared 

 by the slide librarian, Miss Virginia B. McGivney. No. 17, 

 "France: Paris," and No. 18, "The French Riviera," were pre- 

 pared by Miss Paula C. Lambert, who generously contributed 

 her services. 



The complete series includes the following: 



1. The War Zone of Western Europe in Time of Peace 



2. The Panama Canal 



3. Our Forests and Their Uses 



4. The Birds of Our Parks
