Written by a geologist of national reputa- 

 tion, this textbook covers a year of college 

 ■work in the essentials of modern geology. It 

 succeeds in the difficult task of presenting the 

 subject in a manner that is easily comprehen- 

 sible to the average student. 



In the section on physical geology, the 

 human relation has been emphasized vflienever 

 possible, -while in the historical section the 

 history of life from the evolutionist's point of 

 view has been taken up in broad outline. The 

 illustrations, o! which there are nearly 600, 

 are one of the most vital and helpful features 

 of the book.

 Day* 



The Fundamental In- 

 dustry of Farming 



was generally learned only through actual work 

 on the farm. Nowadays agricultural schools 

 and colleges are supplementing such practical 

 applications in each subject, with information 

 from the man who knows how — who has spent 

 his life in perfecting the methods of his par- 

 ticular farming interest. 



No other series of agricultural texts will be 

 found a more authoritative or helpful guide 

 for agricultural students and fanners than the 

 Country Life Education Series. Each book 

 is written by an expert in his line, and each 

 represents scientific theory, correlated with 

 the most successful farm practice.
