While Ali Baba took these measures, the captain of the forty robbers returned to the forest with inconceivable mortification. He did not stay long: the loneliness of the gloomy cavern became frightful to him. He determined, however, to avenge the fate of his companions, and to accomplish the death of Ali Baba. For this purpose he returned to the town and took a lodging in a khan, and disguised himself as a merchant in silks. Under this assumed character, he gradually conveyed a great many sorts of rich stuffs and fine linen to his lodging from the cavern, but with all the necessary precautions to conceal the place whence he brought them. In order to dispose of the merchandise, when he had thus amassed them together, he took a warehouse, which happened to be opposite to Cassim's, which Ali Baba's son had occupied since the death of his uncle. He took the name of Cogia Houssain, and, as a newcomer, was, according to custom, extremely civil and complaisant to all the merchants his neighbors. Ali Baba's son was, from his vicinity, one of the first to converse with Cogia Houssain, who strove to cultivate his friendship more particularly. Two or three days after he was settled, Ali Baba came to see his son, and the captain of the robbers recognized him at once, and soon learned from his son who he was. After this he increased his assiduities, caressed him in the most engaging manner, made him some small presents, and often asked him to dine and sup with him, when he treated him very handsomely. Ali Baba's son did not choose to lie under such obligation to Cogia Houssain; but was so much straitened for want of room in his house that he could not entertain him. He therefore acquainted his father, Ali Baba, with his wish to invite him in return. Ali Baba with great pleasure took the treat upon himself. "Son," said he, "to-morrow being Friday, which is a day that the shops of such great merchants as Cogia Houssain and yourself are shut, get him to accompany you, and as you pass by my door, call in. I will go and order Morgiana to provide a supper." The next day Ali Baba's son and Cogia Houssain met by appointment, took their walk, and as they returned, Ali Baba's son led Cogia Houssain through the street where his father lived, and when they came to the house, stopped and knocked at the door. "This, sir," said he, "is my father's house, who, from the account I have given him of your friendship, charged me to procure him the honor of your acquaintance; and I desire you to add this pleasure to those for which I am already indebted to you." Though it was the sole aim of Cogia Houssain to introduce himself into Ali Baba's house that he might kill him, without hazarding his own life or making any noise, yet he excused himself and offered to take his leave; but a slave having opened the door, Ali Baba's son took him obligingly by the hand, and, in a manner, forced him in.
