The forest has a different effect on each child. For Jack, it was a very stressful experience. Being on the island has changed him, turning him from a child to an animal. The author shows in a paragraph his descent into madness. The text says, “...[he] became less a hunter than a furtive thing, ape-like among the tangle of trees.” (Golding, 39) He has become so involved in his hunting that he now appears to be swinging on the trees like a monkey. The passage also states, “...and then the surge of blood again. He passed like a shadow under the darkness of the tree and crouched.” The imagery shows a boy, hiding, blood rushing throughout his face, devoted to hunting a wild pig. Jack has surrendered most of his manners to his savage-like instincts.
