Conflicts are rising

 Ralph tries to set things in order. He reestablishes rules regarding the fire and where to go to the bathroom. The subject of the beast is brought up. Jack argues the island is too small for a beast. One of the boys claims the beast comes from the sea. The boys argue. Simon suggests that they are the beast. They all make fun of him. The arguing continues. Jack storms away from the meeting with his hunters, who make horrific sounds in the darkness. Piggy begs Ralph to call them back with the conch. He longs for grown ups to make things right.  I believe that Simon is right. The beastie symbolizes the monsters that the boys are becoming. They are afraid of turning savage.
