What caused the friction between Ralph and Jack in Lord of the Flies?

Before all else Ralph wants to be rescued and his determination to keep the signal fire lit at all costs is evidence of this. Ralph also feels a sense of responsibility, as the elected chief. He wants to improve living conditions for all the boys by building shelters and using specified toilet locations. He sees the need to maintian order in their lives as a way to avoid their slide into savagery. On the other hand Ralph is also aware of the lure of hunting, bathing and 'playing at savages.'During the journey to find the beast, when he throws his spear at a boar and takes part in the mock hunt of Robert, Ralph feels the attraction of hunting and the need to kill very strongly indeed.
