What does Piggy believe can still bring all the boys together in Lord of the Flies chapter 11?

Piggy seemed to think that the presence of the conch would help to restore common sense and order to the boys who had become part of Jack's tribe. He hoped that by reminding the boys of the sensible course which Ralph had tried to adopt he might persuade them to give up their 'savage' ways. Unfortunately Piggy's manner of speaking simply infuriated the boys, who objected to being spoken to as if they were naughty schoolboys being chastised by an elderly fat school teacher.
