Published in May 1921 
A Geography as readable as the most interesting novel 
The author’s aim is to provide an authoritative study of the 
state, presenting in compact form the wide range of physical 
influences which make up the geographic env ironment in which 
men live. 
The natural features and natural resources of the state are 
treated in some detail. The great occupations of mankind— 
agriculture, mining, manufacturing, transportation, and trade 
—are discussed with sufficient fulness to give an adequate 
idea of their development and present importance within the 
state. The population census of 1920 for Illinois is treated 
in a final chapter. The book is designed to be of interest 
to the busy citizen who wishes to know his state as a unit in 
its present-day activities; to teachers and pupils who would 
know Ilhnois well enough to interpret other regions in com- 
parison with the home state; to all who wish to learn the 
reasons for the high rank of [llinois in many lines of human 
endeavor. 
The reader will find among the references listed in the bibli- 
ography a wealth of material with which to continue a study 
of the state and its resources as fully as may be desired. 
Abounds with drawings, maps, illustrations, and colored insert maps
