Read the excerpt from Jungle Book: Mowgli's Brothers. "He is our brother in all but blood," Akela went on; "and ye would kill him here! In truth, I have lived too long. Some of ye are eaters of cattle, and of others I have heard that, under Shere Khan's teaching, ye go by dark night and snatch children from the villager's door-step. Therefore I know ye to be cowards, and it is to cowards I speak. It is certain that I must die, and my life is of no worth, or I would offer that in the man-cub's place. But for the sake of the Honour of the Pack, – a little matter that, by being without a leader, ye have forgotten, – I promise that if ye let the man-cub go to his own place, I will not, when my time comes to die, bare one tooth against ye. I will die without fighting. That will at least save the Pack three lives. More I cannot do; but, if ye will, I can save ye the shame that comes of killing a brother against whom there is no fault, – a brother spoken for and bought into the Pack according to the Law of the Jungle."
