which was prepared with the assistance and under the super- 

 vision of C.-E. A. Winslow, Curator of Public Health. The 

 folio consists of a series of fifteen photographic enlargements 

 illustrating the spread of disease and its prevention. Twelve 

 of these folios, each accompanied by an explanatory guide, 

 have been added to the circulating collections, and are much 

 appreciated, especially by the high school teachers. Two 

 additional public health folios are being prepared under the 

 supervision of Professor Winslow, and will be issued in 1913. 

 The distribution of the regular circulating collections to 

 the schools has progressed as usual, and has required the 

 services of two messengers. During the year, 491 schools 

 have been on our list, as follows: 



Manhattan 169 



Brooklyn 153 



Queens 48 



Bronx 49 



Richmond 21 



Corporate Schools 21

The total number of pupils reached is 1,275,890, a larger

Fifty collections were rented to the Newark schools and 

 were studied by 35,821 pupils, and in a few cases the collec- 

 tions have been loaned to other outside institutions. 



Upon request of Miss Annie Carroll Moore, the Supervisor 

 of Children's Rooms of the New York Public Libraries, the 

 department has continued to supply various branch libraries 

 of the city with ethnological collections illustrating the culture 

 of the Indians, Chinese, Japanese, Koreans and Africans.
