any interculture, except lioelng^, gave respectively 60 and 80 lbs. 
less corn per acre than the uninanured and untouched plots ; 
while two plots similarly treated, but with the addition of forking; 
between the rows, showed a decrease of 175 lbs. and 165 lbs, re- 
spectively, when compared with the ordinary wheat. The potatoes 
planted between the wide-drilled wheat were a complete failure.
