In "Lord of the Flies" Golding uses many objects as symbols,such as the spear.The spear can be interpreted as a symbol that reminds the reader of the conflicts the boys have created for themselves.This spear symbolizes the danger that is directed to both groups of boys,equally capable of affecting the side that points it or is its target.The time it is created and used is significant as well.The boys are hunting Ralph with that spear which is a direct threat to him,but in that hunt, they set fire to the forest to try and lure Ralph out.What they don't realize is that by setting that fire,they are putting themselves in the line of danger just as much as Ralph.Besides the fact that they could die from the fire,they are also destroying valuable resources they have such as the fruit they must eat to survive.A lesson the author may be trying to get across is that by trying to harm someone else,you are simply harming yourself.

If you glance back a few chapters, you will see that Jack did the same thing in his sacrifice to the beast. He cut off the pig's head, then jammed its head on a stick planted in the ground. He plans to do the same with Ralph.
