Jack challenges Ralph's authority as a chief. What is said and how does it end?

In chapter 8, at the meeting, Jack tells the other boys that the beast is a hunter, and he informs them that Ralph thinks that the boys are cowards. He continues his attack on Ralph, claiming that Ralph is no proper chief, for he is a coward himself. Jack asks the boys if they want Ralph to be fired as chief. When nobody agrees with him, Jack runs off in tears. He asserts that he is no longer going to be part of Ralph's lot. Jack leaves the group on the beach.
