former prodigality had occasioned; taking an oath never to give an inhabitant of Bagdad any entertainment while he lived.  He drew the strong box into which he had put the rents received from his estates from the recess where he had placed it in reserve, put it in the room of that he had emptied, and resolved to take out every day no more than was sufficient to defray the expense of a single person to sup with him, who, according to the oath he had taken, was not of Bagdad, but a stranger arrived in the city the same day, and who must take his leave of him the following morning.

Conformably to this plan, Abou Hassan took care every morning to provide whatever was necessary, and towards the close of the evening, went and sat at the end of Bagdad bridge; and as soon as he saw a stranger, accosted him civilly invited him to sup and lodge with him that night, and after having informed him of the law he had imposed upon himself, conducted him to his house.  The repast with which Abou Hassan regaled his guests was not costly, but well dressed, with plenty of good wine, and generally lasted till the night was pretty far advanced; instead of entertaining his guests with the affairs of state, his family, or business, as is too frequent, he conversed on different agreeable subjects.  He was naturally of so gay and pleasant a temper, that he could give the most agreeable turns to every subject, and make the most melancholy persons merry.  When he sent away his guest the next morning, he always said, “God preserve you from all sorrow wherever you go; when I invited you yesterday to come and sup with me, I informed you of the law I have imposed on myself; therefore do not take it ill if I tell you that we must never see one another again, nor drink together, either at home or any where else, for reasons best known to myself:  so God conduct you.”

Abou Hassan was very exact in the observance of this oath, and never looked upon or spoke to the strangers he had once entertained; if he met them afterwards in the streets, the squares, or any public assemblies, he affected not to see them, and turned away to avoid them, that they might not speak to him, or he have any communication with them.  He had acted for a long time in this manner, when, one afternoon, a little before sunset, as he sat upon the bridge according to custom, the caliph Haroon al Rusheed came by, but so disguised that it was impossible to know him; for that monarch, though his chief ministers and officers of justice acquitted themselves of their duty very punctually, would nevertheless inform himself of every thing, and for that purpose often disguised himself in different ways, and walked through the city and suburbs of Bagdad, sometimes one way and sometimes another.  That day, being the first of the month, he was dressed like a merchant of Moussul, and was followed by a tall stout slave.
