The Caliph being tired with the walk and the excitement of the morning, slept so long and soundly that it was night and quite dark when he awoke. And being even then but half awake he did not realize that he was no longer in the castle-dungeon; therefore, perceiving that it was not yet light, he turned over and went to sleep again. In a few hours' time, in the midst of a dream that he was in his own palace at Bagdad and presiding at some great feast, he awoke once more, saw that it was beginning to be light, remembered where he was, and found himself exceedingly hungry. Going, therefore, very quietly into the next apartment, he found the innkeeper lying there soundly asleep, and on the table the remains of a substantial supper. At once seating himself, the Caliph was not long in finishing the repast and assuaging the pangs of hunger.
Having all his life been used to eat and drink whatever he required, without any thought of payment, it is very likely that he might have eaten his meal and departed without the least concern or thought of the fact that he possessed at that moment nothing to pay for it. However, it so fell out that he was enabled to recompense his involuntary host very handsomely. For after he had finished eating, and before he rose from his seat, he heard a slight rustling sound outside the room, as though some one were stealthily approaching.
Now the Caliph, before lying down to rest on the previous afternoon, had taken the precaution to bestow the mysterious and wonderful charm he had picked up, in a place of safety. He had put it inside his turban, in such a way that he could feel it pressing like a soft elastic pad upon his forehead. And therefore, in virtue of his contact with that charm, he was still invisible to every other human being.
Such being the case, the thief peering into the room saw no one but the keeper of the inn, who was sleeping very soundly. Entering, therefore, with noiseless tread, his feet being bare, he approached the sleeper, and extracted very dexterously a small packet of coin which he carried secreted in his girdle. With this packet the thief glided from the room, and stopping outside but a single instant to place it inside the folds of his own turban, he walked briskly away.
The Caliph followed him closely. About a hundred yards from the door of the inn there flowed a small stream or brook, across which the only bridge was a couple of planks. Just as they arrived at this point the Caliph took off the fellow's turban, and, with a push from behind, threw him into the water. The stream was neither deep nor swift, and the thief soon picked himself up, scrambled to the other side, and then, without once looking back, took to his heels, being fully persuaded that it was the man he had just robbed who had pursued and overtaken him. The Caliph, after taking the parcel of coin out of the turban, which he then threw away, walked quietly back towards the inn, without deigning to bestow another thought on the thief whom he had thrown into the water.
Before he reached the door of the inn, he saw the innkeeper, who had awoke and discovered his loss, rush out of the house wild and bareheaded, his turban having tumbled or been knocked off in his excitement. Running past the invisible Caliph, and loudly cursing all villains and robbers, and especially that one who had just taken his money, he caught sight of the thief himself, scrambling up, dripping wet, on to the opposite bank of the stream, and, with much vociferation, he continued in hot pursuit. The noise he made brought out, of course, all those who had been passing the night at the inn, and very naturally they all commenced at once to follow the pursuer and pursued.
The Caliph then quietly entered the deserted house, and placing the packet of money carefully in the innkeeper's turban, where he would be sure to find it on his return from the chase, he left, and taking another road, and one leading, as far as he could judge, in the direction of his own dominions, he continued his journey.
He walked along for some hours without meeting any one except a few peasants, or encountering any noteworthy incident whatsoever.
At length he became tired with his long march, and the heat of the noontide sun became so oppressive, that, espying a thick clump of trees at a short distance from the road, he gladly made his way to that pleasant shelter, lay down on a grassy bank, with a log for his pillow, and composed himself to rest and sleep.
On waking, after two or three hours of very sound and refreshing sleep, he found that owing to some change in his position his turban had fallen off. This, in itself not very serious or remarkable accident, gave him on the present occasion much apprehension and concern. For in his turban he had placed, as has been mentioned, the invisible object, whatever it might be, which had in some inexplicable manner conferred upon him also, while he was in contact with it, the condition of invisibility.
