Economic Geography 



of North America 



By CHARLES C. COLBY 



Assistant Professor of Geography, the University of Chic 



The fundamental idea of the book is to ma 

 available to the busy teacher the naaterial on tl 

 subject which is scattered widely through liteB 

 ture. The course which has been given forj 

 number of years at the University of Chica 

 has resulted in the collection and,organizatior 

 the material most suitable for the purpose. 



The book contains short magazine artic 

 and materials from Canadian, Mexican, an^ 

 United States government publications. The 

 selection of the material has been governed by 

 the concept that there is a direct relation be- 

 tween the environment and the economic activ- 

 ities of the region. The author aims to survi 

 the different sections of the country from tl 

 viewpoint of industrial opportunity.

The Geography of Illinois 



By DOUGLAS C. RIDGLEY 



Professor of Geography in the Illinois State Normal University 



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 

 environment in which men Hve. 



The natural features and natural resources of the state are treated in some detail. 

 The great occupations of mankind — agriculture, mining, manufacturing, trans- 

 portation, and trade — are discussed with sufficient fulness to give an adequate 

 idea of their development and present importance within the state. The popula- 

 tion 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 Illinois well enough 

 to interpret other regions in comparison with the home state; to all who wish to 

 learn the reasons for the high rank of Illinois in many lines of human endeavor. 



Abounds with drawings, maps, illustrations, and colored insert maps
