" He would spend entire days in the foothills, ostensibly searching for gazelle, but on the few occasions that he came close enough to any of the beautiful little animals to harm them he invariably allowed them to escape without so much as taking his rifle from its boot. The ape-man could see no sport in slaughtering the most harmless and defenseless of God's creatures for the mere pleasure of killing. In fact, Tarzan had never killed for "pleasure," nor to him was there pleasure in killing. It was the joy of righteous battle that he loved—the ecstasy of victory. And the keen and successful hunt for food in which he pitted his skill and craftiness against the skill and craftiness of another; but to come out of a town filled with food to shoot down a soft-eyed, pretty gazelle—ah, that was crueller than the deliberate and cold-blooded murder of a fellow man. Tarzan would have none of it, and so he hunted alone that none might discover the sham that he was practicing. "
