"That's what the shell's called. I'll give the conch to the next person to speak. He can hold it when he's speaking."
"I'm going by off by myself. He can catch his own pigs. Anyone who wants to hunt when I do can come too."
" Ralph screamed, a scream of fright and anger and desperation. His legs sraightened, the screams became continuous and foaming."
This is when the boys first arrive on the island. Where they are most civilized and they are in order. The conch represents the civilized human beings they are
"When we was coming down I looked through one of them windows, I saw the other part of the plane. There was flames coming out."
This shows the boys picking sides and not staying together and being civilized. Jack doesnt care about the conch anymore even though it keeps the boys together
KILL THE BEAST! CUT ITS THROAT SPILL THE BLOOD!
The boys have gone completely savage and crazy and have lost humanity for the world. Jacks tribe is savage and dirty. There is no point of using the conch because it broke and there is no need for it.
The end(Pigs Head)
"Piggy fell forty feet and landed on his back across the square red rock in the sea. His head opened and stuff came out and turned red."
when the boys first arrived at the island, they are theses young boys. They are scared, innocent, lonely, and don't know what to do on the island.
The boys are starting to see the real world, they are starting to realize what they have to do to survive on the island, survival of the fittest. So, Jack killed a pig and the boys have never done this, they loose most of their sight to innocence.
The boys have killed Simon! They are savage and ruthless boys, who are not scared and have lost sight of reality. The pig head represents the loss of piggy and the loss of innocence between all of the boys. How Ralph was the only one who truly matured and how Jack lost sight of what reality was at a young age.
