As Abou Hassan had waved his hand to direct the attention of his guests to the splendid results of his new system of trading and his magnificent surroundings it flashed upon the mind of the Caliph that he had seen that hand before. The shapely fingers, and the rings containing many precious stones of unusual size and beauty, recalled to him irresistibly the hands of the old man with his face shielded by the huge green shade over his eyes, whom he had been watching earlier in the evening. So Abou Hassan, the Fortunate Merchant, the young and sparkling host of this gay party, was identical with the villainous purchaser of stolen goods, whose base pursuits the ointment had revealed to him. The new plan of naming one price and taking no other had been practised only with those who feared justice and practised robbery. The Caliph, absorbed in these thoughts, observed nothing that was going on about him until Abou Hassan approached him, and, addressing him, personally requested him to rise and accompany himself and his friends into the garden. Then the Caliph, rising and thanking Abou Hassan for his hospitality, declared that now the moon was up he must pursue his journey, and, taking leave together with Giafer, he left the house of the Fortunate Merchant and returned immediately to the palace.

At length, just as the Caliph was beginning to speculate whether the man could possibly have become suspicious and have effected his escape, Abou Hassan came quickly along the street, hastening evidently to the house where he was to assume his disguise and enter on his business. As he arrived almost exactly opposite to the spot where Haroun and Giafer were standing in the obscurity of the great gateway, there approached from the right or opposite direction that same old beggar and miser who had accosted the Caliph on the previous evening. On perceiving some one before him he began immediately to solicit alms in the whining tone common to his class. "An old man," he said, "a very old man, my lord, ragged, hungry, without shelter." Abou Hassan, as he heard the voice, exclaimed--
