If we ask any intelligent farmer why he has organized his farm as he has; why he is raising the crops that he raises in just the proportions that he is raising them; why he has as much as he has of each class of livestock; he is likely to tell us that he is doing it that way because he believes it will bring him more money from what he is putting into it than he could get by any other use of his land, labor, equipment and other resources.
