tisfaction and comfort to hear you talk so
reasonably is inexpressible: and it gives me as much joy as if I
had brought you into the world a second time; but I must tell you
my opinion of this adventure, and observe one thing which you may
not have noticed; the stranger whom you brought home the evening
before your illness to sup with you went away without shutting
your chamber-door after him, as you desired; which I believe gave
the devil an opportunity to enter, and throw you into the
horrible illusion you have been in: therefore, my son, you ought
to return God thanks for your deliverance, and beseech him to
keep you from falling again into the snares of the evil spirit."

"You have found out the source of our misfortunes," answered Abou
Hassan. "It was that very night I had this dream which turned my
brain. I bade the merchant expressly to shut the door after him;
and now I find he did not do it. I am persuaded, as well as you,
the devil finding it open came in, and filled my head full of
these fancies. The people of Moussul, from whence this merchant
came, may not know how we at Bagdad are convinced from experience
that the devil is the cause of troublesome dreams when we leave
our chamber-doors open. But since, mother, you see I am, by the
grace of God, so well recovered, for God's sake get me out of
this horrible place, which will infallibly shorten my days if I
stay here any longer." The mother, glad to hear her son was so
well cured of his foolish imagination of being caliph, went
immediately to the keeper, and assuring him that he was very
sensible and well, he came, examined, and released him in her
presence.

When Abou Hassan came home, he stayed within doors some days to
recover his health by better living than he had found at the
hospital. But when he had recovered his strength, and felt no
longer the effect of the harsh treatment he had suffered in his
confinement, he began to be weary of spending his evenings alone.
He accordingly entered again upon the same plan as he had before
pursued; which was, to provide enough every day to regale a
stranger at night.

The day on which Abou Hassan renewed his custom of going about
sun-set to the end of Bagdad bridge to stop the first stranger
thee offered, and invite him to do him the honour of supping with
him, happened to be the first day of the month, that which the
caliph always set apart to go in disguise out of some one of the
gates to observe what was
