 important farm crops have largely lost the power to 

 compete with weeds. They have been so altered from 

 their original wild state by man that were they left to 

 themselves they would become extinct in a few years. 

 Our cropping methods must therefore be intelligently

 land is not to be lost.

 in the struggle. It remains only for him to create condi-
