Source Book for the Economic Geography 

 of North America 



By CHARLES C. COLBY 



Assistant Professor of Geography, the University of Chicago 



The fundamental idea of the book is to make available to the busy teacher the 

 material on this subject which is scattered widely through literature. The course which 

 has been given for a number of years at the University of Chicago has resulted in the 

 collection and organization of the material most suitable for the purpose. 



The book contains short magazine articles and materials from Canadian, Mexican, 

 and United States government publications. The selection of the material has been 

 governed by the concept that there is a direct relation between the environment and 

 the economic activities of the region. The author aims to survey the different sections 

 of the country from the 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 live. 



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.
