PREFACE 



THE most successful farmers of the present day 

 are those who work in harmony with the forces and 

 laws of nature which control the growth and de- 

 velopment of plants and animals. These men have 

 gained their knowledge of those laws and forces 

 by careful observation, experiment and study. 



This book is a result of the author's search for 

 these facts and truths as a student and farmer and 

 his endeavor as a teacher to present them in a sim- 

 ple manner to others. 



The object in presenting the book to the general 

 public is the hope that it may be of assistance to 

 farmers, students and teachers, in their search for 

 the fundamental truths and principles of farming. 



In the first part of the book an attempt has been 

 made to select the most important and fundamental 

 truths and principles underlying all agriculture and 

 to present them in the order of their importance, 

 beginning with the most important. 



An endeavor has been made to present these 

 truths to the reader and student in a simple and in- 

 teresting manner. As far as possible each advance 

 step is based on a previously stated fact or truth. 

 A number of side truths are introduced at various 

 places.
