Then Aladdin ordered the jewelers to stop their work, and to take back all the Sultan's jewels as well as their own. And that night he called up the Slave of the Lamp once more, and bade him finish the window. This was done before the morning, and great was the surprise of the Sultan and all his workmen.
Now Aladdin did not grow proud of his great riches but was gentle and courteous to all, and kind to the poor, so that the people all loved him dearly. He fought and won many battles for the Sultan, and was the greatest favorite in the land.
But far away in Africa there was trouble brewing for Aladdin. The wicked old Magician who had pretended to be Aladdin's uncle found out by his magic powers that the boy had not perished when he left him underground, but had somehow managed to escape and become rich and powerful.
"He must have discovered the secret of the lamp," shrieked the Magician, tearing his hair with rage. "I will not rest day or night until I shall have found some way of taking it from him."
So he journeyed from Africa to China, and when he came to the city where Aladdin lived and saw the wonderful palace, he nearly choked with fury to see all its splendor and richness. Then he disguised himself as a merchant, and bought a number of copper lamps, and with these went from street to street, crying, "New lamps for old."
As soon as the people heard his cry, they crowded round him, laughing and jeering, for they thought he must be mad to make such an offer.
Now it happened that Aladdin was out hunting, and the Princess sat alone in the hall of the jeweled windows. When, therefore, she heard the noise that was going on in the street outside, she called to her slaves to ask what it meant.
Presently one of the slaves came back, laughing so much that she could hardly speak.
"It is a curious old man who offers to give new lamps for old," she cried. "Did any one ever hear before of such a strange way of trading?"
The Princess laughed too, and pointed to an old lamp which hung in a niche close by.
"There is an old enough lamp," she said. "Take it and see if the old man will really give a new one for it."
The slave took it down and ran out to the street once more, and when the Magician saw that it was indeed what he wanted, he seized the Magic Lamp with both his hands.
