PREFACE 



The aim of this volume is to set forth in 

 a plain way the salient facts of that new 

 branch of agricultural science which is 

 now imiversally known as dry-farming. 

 The writer has taken special care to deal 

 only with the data obtained by rehable 

 farmers, experiment-station workers, to- 

 gether with the results of his own experi- 

 ence. It is therefore hoped that this little 

 manual Avill form a safe and useful guide 

 to those thousands of settlers who are 

 ceaselessly pouring into the great semi- 

 arid plains of the United States and 

 Western Canada and be of genuine value 

 as well to all those interested in the study 



and practice of agriculture,
