Ralph brings up a lot of important issues he thinks needs attention, what are they?

Ralph blows the conch shell and the assembly gathers. He begins the assembly seriously, telling them that they are there not for making jokes or for cleverness. He reminds them that everyone built the first shelter, which is the most sturdy, while the third one, built only by Simon and Ralph, is unstable. He admonishes them for not using the appropriate areas for the lavatory. He also reminds them that the fire is the most important thing on the island, for it is their means of escape. He claims that they ought to die before they let the fire out. He directs this at the hunters in particular. He repeats the rule that the only place where they will have a fire is on the mountain. Addressing the spreading fear among the littluns, Ralph then attempts to demystify the question of the "beastie" or monster. He admits that he is frightened himself, but their fear is unfounded. Ralph again assures the group that there are no monsters on the island.
