THE POTATO 27 



"By the use of plenty of alfalfa, mostly fed on 

 the place, he has added to his sandy soil the ele- 

 ment it needed by increasing its organic and humus 

 content, and the sand seems to contain those other 

 elements necessary to the growth of good, clean 

 potatoes." 



The value of aeration is very convincingly il- 

 lustrated by digging into a hill of potatoes grown 

 on heavy, poorly drained and aired soil. The 

 deeper into the hill that tubers are found, the 

 rougher and more diseased they are. It is also a 

 notable fact that the exhibit potatoes from an 

 average field are those that develop close to the 

 surface.
