After a while they catch a sight of a boat sinking with a boy on it calling for help. The children help him aboard to safety ... The four children sail and sing. Not far from the shore they see a girl planting olive-tree branches. The children invite the girl to join them on the boat ... After a while they hear distant children's voice.
