cases ; and they are sent to the schools in groups which 

 are frequently changed. 



The value of these exhibits has been summed up by 

 Doctor Maria Montessori, who, after careful inspection 

 of typical cases, made the following statements in an 

 unsolicited letter: 



"I admire very much the way in which nature is 

 interpreted in this exhibit. The units attract the 

 child's attention and do not teach errors. They truly 

 represent nature. 



"I consider the collection a most desirable contri- 

 bution to school work and education generally. I hope 

 that many more of these beautiful exhibits may be 

 made." 



Ten typical cases of this series are exhibited in 

 Stanley Field Hall. The success of this movement has 

 been greatly aided by the hearty cooperation given by 

 the superintendent, principals and teachers of the 

 schools of Chicago. 



THE LIBRARY 



The work of the Museum Library, briefly told, is to 

 supplement the Museum collections and to facilitate 

 the work of the Scientific Staff. As the Museum seeks 

 to interest and instruct its visitors in its exhibits, so 

 the library endeavors to supply books descriptive of 

 those subjects; for no exhibit, however carefully or 

 fully labeled, can give all the information that may be 

 desired by a specially interested visitor. 



The library is divided into four sections, corres- 

 ponding to the four departments of the Museum. In 

 the section of the Department of Anthropology may be 

 found books pertaining to the history of the American 

 Indian, the natives of the Philippine Islands, Mexico,
