“«All the jungle is thine,» said Bagheera, «and thou canst kill everything that thou art strong enough to kill; but for the sake of the bull that bought thee thou must never kill or eat any cattle young or old. That is the Law of the Jungle.» Mowgli obeyed faithfully. And he grew and grew strong as a boy must grow who does not know that he is learning any lessons, and who has nothing in the world to think of except things to eat.
Mother Wolf told him once or twice that Shere Khan was not a creature to be trusted, and that some day he must kill Shere Khan. But though a young wolf would have remembered that advice every hour, Mowgli forgot it because he was only a boy—though he would have called himself a wolf if he had been able to speak in any human tongue.”
