PREFACE 



The leaders in American farm-life to-day realize that the 

 farmer must be not only a good business man, but he must also 

 be acquainted with the science of agriculture. Therefore this 

 book aims to deal with the business side of farming and to 

 assemble the scientific knowledge of agriculture as studied and 

 practiced by a number of experts. 



In order to make this practical knowledge more accessible to 

 the farmer, technical terms have been eliminated and an easily 

 comprehended terminology has been maintained throughout the 

 book. 



The author is indebted to many experiment stations for their 

 cooperation in supplying information and illustrations, credit 

 for which is given in the pages of this book. 



He is particularly pleased to acknowledge his deep obliga- 

 tions to the International Harvester Company, the Du Pont 

 Powder Works, and the Gould Force Pump Company, for their 

 contributions. 



Grateful acknowledgment is due the Country Gentleman, the 

 Wisconsin Farmer, Doubleday, Page & Co., and the Macmillan 

 Company for extracts taken from their publications. 



The U. S. Department of Agriculture has given valuable 

 service to the editor in furnishing material and in supplying 

 bulletins from which extracts and illustrations have been taken. 



The farmer and his family are the most potent factors in 

 making the United States the greatest producing nation as well 

 as the greatest nation of happy homes. It is therefore hoped 

 that this book will aid in increasing production and happiness 

 among the tillers of the soil.
