Ralph has 3 different strateiges for 'escaping' the hunters. What were they?

From the text:

At first light he would creep into the thicket, squeeze between the twisted stems, ensconce himself so deep that only a crawler like himself could come through, and that crawler would be jabbed. There he would sit, and the search would pass him by, and the cordon waver on, ululating along the island, and he would be free.
