How does Jack propose to deal with the beast in Lord of the Flies? Where do we see this type of behavior historically or in religion?

In chapter 8, after he stormed out of the assembly he'd called because a new vote, Ralph was still elected chief, Jack forms his own tribe.  In their first meeting, he tells the boys that they are going to forget the beast.  But he goes on to say that when they kill something, they will leave something for it. He believes, as he stated at the beginning of chapter 8 before he left the assembly, that the beast is a hunter, too. He believes that it could hunt and kill them if they don't leave a sacrifice for it. Shortly after he declares this at his meeting, he and his hunters kill a pig.  They sharpen a stick at both ends: one end to stick into the ground and the other to stick into the head of the killed pig.  This is the gift he leaves for the beast.  It is this pig's head that Simon "hears" in his trance.  Sacrificing to appease a power has ancient religous roots beginning before recorded time probably.
