Chapter 4 is entitled "Painted Faces and Long Hair," which are powerful symbols that represent the boys' gradual decline into savagery as the hunters paint their faces like barbarians and allow their hair to grow long and unkempt. The masks that Jack and his hunters wear liberate them and are the outward manifestations of their inherently savage nature. Their long hair is another sign of their increasing barbaric personalities and distance from civilization. After being removed from civilization for an extended period of time, the boys' appearance corresponds to their increasingly savage behavior. When Jack initially paints his face, Golding writes,
He [Jack] capered toward Bill, and the mask was a thing on its own, behind which Jack hid, liberated from shame and self-consciousness (89).
Jack's mask allows him to distance himself from civilization and gives him the freedom to behave like a violent, bloodthirsty savage.
Golding also illustrates how the boys are becoming increasingly savage by depicting their insensitive personalities as Roger and Maurice proceed to destroy the littluns' sandcastles on the beach. In chapter 4, Jack also becomes more obsessed with hunting and allows his hunters to neglect their duties maintaining the signal fire, which results in the boys missing a rare opportunity to be rescued when a ship passes. Overall, the chapter's title indicates two powerful symbols that represent the boys' increasingly savage behavior on the uninhabited island.
