Swallows and Amazons

After bathing and eating breakfast the next morning, the children fish for minnows using worms and then use the minnows as bait to catch fish. Their nautical knowledge helps them succeed: They anchor the boat and watch the wind direction so that their floats don’t drift. Roger catches a yard-long pike that disgorges a perch and then flops back into the water. Susan cleans and fries the perch.

The children decide to name various places on the island: the Landing-Place, the Harbor, the Western Shore, the Camp, a promontory called Darien, Houseboat Bay, Shark Bay. They do not name their own island because of the possibility that it has already been named by the people who left the fireplace behind.

The following day, taking turns with their telescope, they observe various boating activities on the lake and see a sailboat heading for Houseboat Bay.

A loud bang and smoke come from the area of Houseboat Bay. The children conclude that a sailboat is fighting the pirate who lives on the houseboat. Suddenly, the sailboat, helmed by two girls dressed in caps, shorts, and knickerbockers (baggy pants), sails straight to the island. The Walkers hide in case the girls, whose sailboat is called the Amazon, are enemies.
