In chapter 10, Jack has set himself up as chief over his own tribe, which consists of all the biguns except Ralph, Samneric, and Piggy. Jack abuses his new-found power by using violence against members of his own tribe and against Ralph's group, using fear and deception to keep control of the boys, and stealing the property of others. Because Jack was angry at Wilfred for an unspecified offense, he tied the boy up and kept him tied for hours, then beat him. When Jack determines they need a way to start their own fires, he plans a midnight raid on Ralph's camp. During that raid, Jack, Roger, and Maurice use violence--"hitting, biting, scratching." Jack deliberately and deceitfully instills fear in his own boys as a way of binding them to the group and to him. He tells them that Ralph's group will "try to spoil things we do," which is a lie. He then warns them of how "the beast might try to come in," reminding them of their struggle against the "beast" (really Simon) at the beach. When one of the other boys questions whether they killed the beast, Jack lies and says no, then says they must leave pigs' heads for it to "keep on the right side of him." This is all deception on Jack's part, designed to make the boys afraid and to bind them together against common enemies. Finally, in a horrendous abuse of power, Jack steals Piggy's glasses, a crime that violates not only Piggy's property rights but also his human rights, since without the glasses his life is severely impaired.
Words that show the sociological status of Jack's group are "tribe," "Chief," "defenders of the gate" or "watchers at the gate," "hunters," and "others." Jack makes sure the others address him as "Chief," showing his superior authority. Members of his tribe are identified by their function, and those outside the tribe are called simple "the others." However, Golding refers to all the boys of Jack's tribe simply as "savages."
