LOTF (Chapter 11) - "Castle Rock"

The next morning, Ralph and his few companions try to light the fire in the cold air, but the attempt is hopeless without Piggy’s glasses. Piggy, squinting and barely able to see, suggests that Ralph hold a meeting to discuss their options. Ralph blows the conch shell, and the boys who have not gone to join Jack’s tribe assemble on the beach. They decide that their only choice is to travel to the Castle Rock to make Jack and his followers see reason.
