Agricultural Text Books for High Schools 



The four agricultural books described below are planned especially for High 

 Schools in which agriculture is taught. They constitute a complete four year 

 graded course. Each book is complete in itself and is prepared to cover the sub- 

 ject as thoroughly as the time allotted to agriculture in one year will permit. 



They are thoroughly practical; they discuss subjects in their logical order, con- 

 tain laboratory exercises and experimental work, and a list of questions after each 

 chapter to emphasize the important features of each lesson. These books 

 constitute a complete, concise and practical course that will meet the urgent need 

 of the modern agricultural High School.
