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:
