Another female slave hearing this, said: "Now you speak of lamps, I know not whether the princess may have observed it, but there is an old one upon a shelf of the prince's robing-room. If the princess chooses, she may have the pleasure of trying if this fool is so silly as to give a new lamp for an old one, without taking anything for the exchange." The lamp this slave spoke of was the wonderful lamp, which Aladdin had laid upon the shelf before he departed for the chase: this he had done several times before; but neither the princess, the slaves, nor the eunuchs had ever taken notice of it. At all other times except when hunting he carried it about his person. The princess, who knew not the value of this lamp, and the interest that Aladdin, not to mention herself, had to keep it safe, entered into the pleasantry, and commanded a eunuch to take it and make the exchange. The eunuch obeyed, went out of the hall, and no sooner got to the palace gates than he saw the African magician, called to him, and showing him the old lamp, said: "Give me a new lamp for this?" The magician never doubted but this was the lamp he wanted. There could be no other such in the palace, where every utensil was gold or silver. He snatched it eagerly out of the eunuch's hand, and thrusting it as far as he could into his breast, offered him his basket, and bade him choose which he liked best. The eunuch picked out one, and carried it to the princess; but the exchange was no sooner made than the place rang with the shouts of the children, deriding the magician's folly. The African magician gave everybody leave to laugh as much as they pleased; he stayed not long near the palace, but made the best of his way, without crying any longer; "New lamps for old ones." His end was answered, and by his silence he got rid of the children and the mob. As soon as he was out of the square between the two palaces, he hastened down the streets which were the least frequented; and having no more occasion for his lamps or basket, set all down in an alley where nobody saw him: then going down another street or two, he walked till he came to one of the city gates, and pursuing his way through the suburbs, which were very extensive, at length reached a lonely spot, where he stopped for a time to execute the design he had in contemplation, never caring for his horse which he had left at the khan; but thinking himself perfectly compensated by the treasure he had acquired.
