PART I 



The Geology of the Country traversed by 

 THE Chen-T'ai Railway : Western Chihli 

 AND Eastern Shansi 



This section of country contains one of the 

 most extensive and important coalfields in China, 

 and therefore deserves closer attention than the 

 writer has been able to give it. The following 

 notes have been gathered during several journeys 

 by rail between Shih-chia-chuang and T'ai-yiian 

 Fu, so that the conclusions drawn therefrom can 

 only be considered as tentative and not final. It 

 is hoped, however, that they will be of value, as 

 this district has not been too thoroughly explored 

 or described.
