In terms of age, there are two specific groups of boys in Lord of the Flies: the bigguns (the older boys) and the littluns (the younger boys). Among the older boys, there is the choir, led by Jack; all of the others not part of the choir initially become allied with Ralph. Jack's choirboys become the hunters of the group, and they quickly become absorbed with killing the wild pigs that roam the island. It is obvious from the start that Jack has a hunger for power, and he is unhappy that he is not voted the leader instead of Ralph. This power struggle between the two oldest boys appears to be a problem from the first, and it can be anticipated to be a continuing form of conflict. Ralph recognizes that the boys are without the leadership of grownups, and that in order to be rescued, some form of smoky signal fire must be kept going for rescuers to see. Ralph claims that his father, a naval officer, has told him that there are no uncharted islands in these waters, and that eventually the boys will be rescued.
