THE N. W. HARRIS PUBLIC SCHOOL EXTENSION 
OF FIELD MUSEUM OF NATURAL HISTORY 
In addition to the collections in the Museum, the scope of 
the institution is extended by means of maintaining a sys- 
tem of Museum Extension to the Public Schools of Chicago. 
This was accomplished through the benefaction of the late 
Norman Wait Harris, who provided an endowment of $250,- 
000, the income from which is utilized for this purpose. This 
endowment has been supplemented by a contribution of 
$25,000 from the heirs of the Harris Estate. 
The cases prepared for this work, numbering nearly 800, 
are circulated to the public schools of Chicago by means of 
a motor car, especially designed for the purpose. Ten 
examples of these cases are exhibited at the south end of 
Stanley Field Hall.
