A ship picks Sinbad up. The crew explains that the old man was the Shaykh al-Bahr, Old Man of the Sea. They take Sinbad to the City of the Apes, where people must go out in boats at night to avoid the army of apes that always comes in and eats their food. SInbad is told to collect pebbles to throw at the apes; the apes throw back fruit which people collect. Sinbad collects many cocao-nuts, leaves on a ship, and trades his nuts for spices and pearls. He returns to Baghdad and gives alms and clothes to the poor.
