A month after the shipwreck. Through Ernst's narration - and the diary he is keeping of events - the family are still struggling with living/surviving off the land and are growing crops, keeping chickens, rearing wild pigs and a goat. But, prompted by the sudden activity of the island's volcano, they are planning to escape and have improved the raft to make it seaworthy. Parsons and Ben have set up home in a squalid cave on a barren outlying island nearby. They fear the family may surprise them and steal the boat. From their island they observe the unsuspecting Robinson's through a telescope. Parsons is still bent on revenging himself on David. Exploring the island the children find a tunnel leading to a cave with a large carved head and a sarcophagus. Christina removes a large black pearl from the cave.
