There are multiple symbols present in Chapter 6 of LOTF.
The conch symbolizes the right to speak. It is a symbol of leadership, which their chief uses to assert control over them. Above all else, it is a symbol of temporary superiority.
The beast symbolizes the boys' fears. The beast is not real. It is a fictional entity created to give shape to their fears and their worst nightmares. It represents the child inside each of them. Above all else, the beast is a symbol of the boys' fear of being alone without adults.
The fire symbolizes the boys' need to be rescued. It is a beacon to any passing ship. It represents the boys' hope that they will be rescued. That they will leave that terrible island and return to their homes. Above all else, the fire is a beacon of hope.
