1: The Sound of the Shell
Piggy spots a conch shell, and tells Ralph how to use it to make a noise. Ralph does so, and calls all of the other boys on the island who crashed down with the plane. Jack and his Choir, Simon, Sam and Eric, and many other characters join in an assembly (including the littl'uns, which are the youngest kids at about 6 or 7 years old). Rules are set down, and Ralph is to be chief. There is no one else on the island but the young boys, so Jack decides to take his choir out to hunt for wild pigs, although he is unsuccessful in killing a small pig with his knife.
Significance: While Jack's first attempt to kill the pig failed, his quote "next time..." foreshadowed his future of savage hunting.
2: Fire on the Mountain
Ralph then suggests making a signal fire, which would be necessary if they hope to get rescued. The boys scramble off to gather wood to build a fire. Unsure of how to light it, they finally grab Piggy's specs and focus the sunlight to ignite their fire. They were not careful, however, and soon the fire is engulfing half the forest near the mountain. The little boy with the birthmark is noticed to be missing, swallowed up by the raging fire.
Significance: Piggy is averse to most of the other boys, who he thinks are acting like little children (they are children, obviously, but Piggy acts like the adult figure). He cites their irresponsibility in dealing with the fire. Jack also shows signs of belligerence when he argues with Ralph about the signal fire, and claims that "The conch doesn't count on the mountain!"
3: Huts on the Beach
Ignorant to the fussing of the other boys, Simon picks fruit for the littl'uns and makes his way into the jungle finding a clearing. He climbs onto a mat of creepers, and remains there; he enjoys the tranquility of this spot, where he can be in touch with nature.
Significance: Jack is solely concerned with hunting, and cannot see the necessity of other things that can keep them alive. Ralph and Jack are really beginning to fight in this chapter, and it foreshadows much more future conflicts down the line. Simon's actions present him as a very good, peaceful and helpful character, in contrast with many others.
4: Painted Faces and Long Hair
Ralph and the other boys are swimming in the bathing pool later on, when smoke from a ship is spotted in the distance. The signal fire was out , not being watched, obliterating their chances of rescue. Oblivious, Jack and his hunters come proudly marching carrying their first kill, trying to convey their excitement to Ralph. When Ralph yells that a ship passed them by and no fire was going, excuses are made and Jack tries to say that hunting is of utmost importance. In the ensuing fight, Jack punches Piggy, breaking and knocking off his specs.
Finally, the fire is lit again, the pig is roasted, and everyone eats. The hunters reenact the hunt, with a wild tribal dance and one boy being the pig; this is the first time of many that the dance is performed.
Significance: Roger's first showing of aggression foreshadows his becoming a very evil and sadistic figure, Jack's invitation to watch him paint his face is the start of their "evil friendship." Jack's mask of face paint represents a cover that he can hide behind, which liberates and frees him, allowing him to do anything when wearing it, without worrying about any important matters. Jack still does not understand Ralph's concern with the fire, and doesn't seem to care much for getting rescued. The primal dance performed by the hunters highlights their transition into savagery.
