Change in Methods n 



These various figures are given here merely 

 to illustrate the fact that the geographical base 

 of agriculture has changed and that it may be 

 expected still further to change; and that a 

 reaction is likely to follow a great shift. Any 

 shift of considerable area is likely to affect 

 some localities disadvantageously. 



THE SHIFT IN AGRICULTURAL METHOD 



Farming exhibits the remarkable changes 

 that have taken place in the last fifty years 

 in the modes of doing work. The plow is

 mechanical principles and in workmanship. 

 The slight variations in the slope and shape of 

 the moldboard and in the construction of 

 other parts, produce marked results in the 

 effect on the physical condition of the plowed 

 land. The chilled steel construction has pro-
