In the exposition of Lord of the Flies, Ralph and Piggy quickly discern that there are no adults on the island and that they should call everyone together, take names of those present on the island, and have a meeting. Using the conch shell, which Ralph discovers "among the ferny weeds," Piggy has the idea of blowing it to summon the other children:
"We can use this to call the others . Have a meeting. They'll come when they hear us" (16).
Piggy shows Ralph how to hold the conch and instructs him on how to blow it properly, unable to do so himself because of his asthma. Piggy's idea is successful, and the conch made "a deep, harsh note [that] boomed under the palms, spread through the intricacies of the forest, and echoed back from the pink granite of the mountain" (17). Boys immediately begin to respond to the call of the shell, appearing on the beach and straggling out of the forest. The conch shell becomes a symbol of authority, inexorably linked in the boys' mind to the adult world where a man at the airport had a megaphone.
With the conch.
