Describe the hunter's two plans to get Ralph in Lord of the Flies chapter 12?

The first plan which Jack and his hunters put into effect is to send a boulder crashing down from the top of castle rock and into the thicket where Ralph is hiding. When this fails to drive Ralph out of hiding or open up a route by which they can reach him they put into action their second plan. The second plan is to smoke him out, unfortunately the fire which they light quickly gets completely out of control and threatens to destroy the entire island.
