 Chicago, 111.," by Miss Mary Perle Anderson. 



Miss Anderson gave a brief account of the geological history 

 of the ancient Lake Chicago and its succession of beaches, the 

 Glenwood, the Calumet, and the Toleston. These ancient 

 beaches were formed by changes in the lake-level and at the 

 present time are indicated by ridges of wooded land more or less 

 parallel to the present coastal beach of Lake Michigan. The 

 ridges are separated by the low level prairie land which makes 

 up the Chicago plain.
