In our kindlier clime the rich soil, too, produces vegetables and fruits upon which we might do very well, if necessary, without ever eating meat; but in the bleak land where Bobby and Jimmy lived the summer is short and the soil is barren, and there are no vegetables, and no fruits save scattered berries on the inland hillsides. And so it is that here men must depend upon flesh and fish for their existence and they must kill if they would live.
