whats a quote describig the symbolism to the book of the dsrkness

"Within the diamond haze of the beach something dark was fumbling along. Ralph saw it first, and watched till the intentness of his gaze drew all eyes that way."(1)

This is way back in chapter one. It is our first sense that the only bad stuff on the island is the boys themselves. Here Jack and his Choir come along. Note that from afar, Golding describes them as "something dark". Indeed, this will prove to be true.
