At the beginning of Chapter 3, Golding describes Jack as a boy who is slowly becoming a savage hunter. He is crawling on the ground, "dog-like, uncomfortably on all fours yet unheeding his discomfort," and following a trail that he thinks will lead him to a pig. His hair, which Golding describes as "considerably longer than it had been when they dropped in," has become light from the sun. (This is Golding's subtle way of indicating the passage of time.) Because he is so intent on killing a pig, Jack has constructed a makeshift knife:
A sharpened stick about five feet long trailed from his right hand, and except for a pair of tattered shorts held up by his knife-belt he was naked.
Finally, Jack spots a pig, raises his spear, and goes after it. He misses, though, and is disappointed that he has not accomplished his goal.
