TWENTY-NINTH CHAPTER 



SOME LEADING PRINCIPLES. 



A LTOGETHER it must be considered poor policy 

 to grow any kind of crop without proper feed- 

 ing. There are cases, however, where the manure 

 supply is scant, and cannot well be replenished. 

 What shall we do with the amount at our disposal ? 

 The same quantity of plant foods needed for the 

 production of thirty bushels of wheat would be 

 sufficient for that of 165 bushels of potatoes, or 

 forty- five bushels of corn, 600 bushels of apples, or 

 other fruit crops in proportion, or several hundred 

 bushels of beets or carrots, or other vegetables in 

 proportion. 



Thus a certain amount of plant food in the form

 peaches, or strawberries perhaps $300. This shows 

 plainly how foolish it would be to stint orchard and 

 small fruit patches in order to be able to put the 

 manure on the wheat field. And if we have no man-
