When the night came and all the folk had dispersed and gone each his own way, the Khalif said to his Vizier, 'Come, O Jaafer, let us go and amuse ourselves by looking on the other Khalif.' At this, Jaafer and Mesrour laughed, and the three, donning merchants' habits, went out at the privy gate and made their way through the city, in great glee, till they came to the Tigris, where they found the boatman sitting, waiting for them. They embarked with him in the boat and had not sat long, before up came the mock Khalif's barge, with the cresset-bearers crying aloud as of wont, and in it two hundred white slaves other than those of the previous night. 'O Vizier,' exclaimed the Khalif, 'had I heard tell of this, I had not believed it; but I have seen it with my own eyes.' Then said he to the boatman, 'Take these ten dinars and row us along abreast of them, for they are in the light and we in the shade, and we can see them and divert ourselves by looking on them, but they cannot see us.' So he took the money and pushing off, followed in the shadow of the barge, till they came among the gardens and the barge cast anchor before a postern door, where they saw servants standing with a mule saddled and bridled. Here the mock Khalif landed and mounting the mule, rode away with his boon-companions, attended by his suite and preceded by the cresset-bearers crying aloud. Then Haroun and Jaafer and Mesrour landed also and making their way through the press of servants, walked on before them.

'O our lord,' answered they, 'we are foreign merchants, who arrived here this day and were out a- walking to-night, when ye came up and these men laid hands on us and brought us before thee.' Quoth the mock Khalif, 'Since you are strangers, no harm shall befall you; but had ye been of Baghdad, I had struck off your heads.' Then he turned to his Vizier and said to him, 'Take these men with thee; for they are our guests this night.' 'I hear and obey, O our lord,' answered he; and they followed him, till they came to a lofty and splendid palace of curious ordinance, such as no king possesses, rising from the dust and laying hold upon the marges of the clouds. Its door was of teak, inlaid with glittering gold, and by it one passed into a saloon, amiddleward which was a basin of water, with an artificial fountain rising from its midst. It was furnished with carpets and cushions and divans of brocade and tables and other gear such as amazed the wit and defied description. There, also, was a curtain drawn, and upon the door were written these two verses:
