contact with the inside sphere. Under these conditions, 

 waves and billows in the surface of the crust would be formed, 

 producing vast folds. These folds formed mountains, which 

 have been worn by erosion until we can see many of the layers 

 bent and twisted. If, however, there were weak spots in the 

 surface of the earth's crust, one part would slip, leaving the 

 rest elevated. The part remaining in its original position 

 would form a mountain. We called this process faulting.

140. THE SOURCE OF FOOD THE SOIL 



Vegetable food must always be the real source of our energy 

 and sustenance. While meat forms part of our diet, as well 

 as vegetables and fruits, yet we must realize that our meat- 

 producing stock lives upon grains and other plant growths. 



Thus we must in the end depend upon those who will till 

 the soil. Moreover, if these agriculturists would only realize 

 the nobility of their profession, would study and put into
