CHAPTER XVI 

 LESSONS FROM EXPERIENCE 



The Great Plains Region of North America includes 

 a large part of the Prairie Provinces of Canada and most 

 of the United .States lying between the Mississippi Valley 

 and the Rocky Mountains. This large area includes 

 many soils and climatic conditions and its problems 

 therefore, are not the same in all parts. They are, how- 

 ever, sufficiently similar to justify the inclusion under 

 one cover of the experiences of the settlers in its different 

 parts. It has therefore been thought wise to ask some 

 of the leading agronomists in this large area to sum- 

 marize the experience of the best farmers and the re- 

 sults of experiment station work in their respective 

 states and provinces. These summaries, for which the 

 author is very much indebted to the writers, are as fol- 

 lows :
