234 CAMPBELL'S SOIL CULTURE MANUAL 



But the quest for plants that will grow right out upon 

 the western and northern prairies and make good crops 

 under conditions of cultivation used in the humid regions 

 or with little or no care, is destined to be a dead failure. 

 The owners of land in this region must understand now, 

 513 they will some time, that there are no plants anywhere 

 in the world that will make good crops in dry regions 

 without the most careful preparation of the soil. 



Intelligent farmers everywhere will give all possible 

 encouragement to the effort to introduce new and valuable 

 plants, and they will do well to make a study of these 

 plants in relation to the very best systems of cultiva- 

 tion.
