Heaven forbid, replied the caliph, that I, who have been so handsomely entertained by you, should laugh at you; neither do I believe, as much a stranger as I am, that the caliph would be displeased. But let us lay this discourse aside; it is almost midnight, and time to go to bed. With all my heart, said Abon Hassan, I would not be any hindrance to your going to rest; but there is still some wine in the bottle, and, if you please, we will drink it off first. The only thing that I have to recommend to you is, that, when you go out in the morning, if I am not up, you will give yourself the trouble of shutting the door after you, which the caliph promised; and while Abon Hassan was talking, took the bottle and two glasses, and filled his own first, saying, Here is a cup of thanks to you; and then filling the other, put artfully a little powder, which he had about him, into it, and giving it to Abon Hassan, said, you have taken the pains to fill for me all this night, and it is the least I can do to save you the trouble once; come, drink to our good repose. Abon Hassan took the glass, and, to show his guest with how much pleasure he received the honour he did him, whipped it off at once; but had scarcely set the glass upon the table before the powder began to work, and he fell into so sound a sleep, that his head knocked against his knees. The caliph ordered the slave that he had brought along with him, and who came again into the room as soon as he had supped, to take him upon his back, and follow him; but to be sure to observe the house, that he might know it again when he should bring him back; and in this manner the caliph, followed by the slave with Abon Hassan on his back, went out of the house, but without shutting the door after him, as Abon Hassan desired, and went directly to his palace, and, by a backdoor, into his own apartment, where all the officers of his apartment were waiting for him, whom he ordered to undress him, and put him in his bed, which they immediately performed. Then the caliph sent for all the officers and ladies of the palace, and said to them, I would have all those whose business it is to attend my levee wait to-morrow morning upon this man who lies in my bed, and pay the same respect to him as to myself, and obey him in whatever he commands; let him be refused in nothing that he asks for, and be spoken to and answered in every thing he says or does, as if he was the commander of the faithful. In short, I expect you to look upon him as the true caliph, and neglect not the least circumstance. The officers and ladies presently understood that the caliph had a mind to divert himself, and made low bows to show their obedience, and then withdrew, every one full of the part they were to act.
