Susan goes to a sawmill with David, who explains how gnomes cut down dead trees to make furniture and birdhouses. Susan gets bored and goes for a ride on Swift with a little boy named Tom. Swift gets his leg caught in a trap in the forest, and Tom tries to cross a river to get help. The current catches him and he is left hanging on a rock in the middle of the river. Susan gets help from David, and he sends an eagle to pick up Tom. The other gnomes free Swift from the trap.
