 Montana, and Arizona is working on 

 different land. He knows that if he can 

 conserve his moisture he wiU reap an 

 abundant harvest.^ His problem then is 

 how best to store up his small annual 

 rainfall. Show him how to do that and 

 he is fully satisfied. Indeed, it is more or 

 less useless to urge the conservation of 

 fertility on men whose real need is more

 pay, and it is more important for the 

 Western farmer to concentrate his mind 

 on the conservation of soil moisture than 

 on the possible exhaustion of his land in 

 ten years' time. There are, of course,

 problem of moisture supply is much more important than 

 the question of fertility.
