tion has been answered with quite a good deal of cer- 

 tainty. At least a half hundred carefully planned and 

 executed experiments have, by their results, answered in 



favor of shallow cultiva- 

 tion. Since then we have 

 heard much about this 

 new idea in cultivating 

 the soil. But we are in 

 danger of going to the 

 other extreme. Our 

 fathers "plowed" corn ; 

 they cultivated too deep. 

 Some of us, perhaps, cul- 

 tivate too shallow; we 

 get in trouble with weeds ; 

 and because of our thin 

 mulch, let the water get 

 away from the soil. 



In sections where there 

 is much rain, the shal- 

 low extreme may do; but 

 where moisture is de- 

 manded in the North, 

 where the ground is fro- 

 zen for so manv months ; 

 in the semi-arid regions, 

 where the supply is gen- 

 erally limited a deeper 

 mulch and a more effec- 

 tive mulch is to be prefer- 

 red. Four inches, per-
