Kasim, her husband, was at his shop. When he came home, his wife said to him: "Kasim, I know you think yourself rich, but 'Ali Baba is infinitely richer than you. He does not count his money, he measures it." Then she told him the stratagem she had used to make the discovery, and shewed him the piece of money, which was so old that they could not tell in what prince's reign it was coined. Now Kasim, after he had married the rich widow, had never treated 'Ali Baba as a brother, but neglected him; and now, instead of being pleased, he conceived a base envy at his brother's prosperity. He could not sleep all that night, and went to him in the morning before sunrise. " 'Ali Baba," said he, "I am surprised at you; you pretend to be miserably poor, and yet you measure gold. My wife found this at the bottom of the measure you borrowed yesterday".
By this discourse, 'Ali Baba perceived that Kasim and his wife, through his own wife's folly, knew what they had so much reason to conceal; but what was done could not be undone. Therefore, without showing the least surprise or trouble, he confessed all, and offered his brother part of his treasure to keep the secret Kasim rose the next morning long before the sun, and set out for the forest with ten mules bearing great chests, which he intended to fill, and followed the road which 'Ali Baba had indicated. He was not long before he reached the rock, and found the place, by the tree and other marks which his brother had given him. When he reached the entrance of the cavern, he pronounced the words, "Open Simsim!" The door immediately opened, and when he was in, closed upon him. In examining the cave, he was rejoiced to find much more riches than he had expected. He quickly laid as many bags of gold as he could carry at the door of the cavern; but his thoughts were so full of the great riches he should possess, that he could not think of the word to make it open, but instead of "Simsim," said, "Open, Barley!" and was much amazed to find that the door remained fast shut He named several sorts of grain, but still the door would not open, and the more he endeavoured to remember the word "Simsim," the more his memory was confounded, and he had as much forgotten it as if he had never lieard it mentioned. He threw down the bags he had loaded himself with, and walked distractedly up and down the cave, without having any regard to the riches around him.
About noon the robbers visited their cave. At some distance they saw Kasim's mules straggling about the rock, with great chests on their backs. Alarmed at this, they galloped full speed to the cave. They drove away the mules, who strayed through the forest so far, that they were soon out of sight, and then, with naked sabres in their hands^ they approached the door, which, on their captain pronouncing the proper words, immediately opened.
Kasim, who heard the noise of the horses' feet, at once guessed the arrival of the robbers, and resolved to make one effort for his life. He rushed to the door, and no sooner saw the door open, than he ran out and threw the leader down; but he could not escape the other robbers, who, with their scimitars, soon deprived him of life.
The first care of the robbers after this was to examine the cave. They found all the bags which Kasim had brought to the door, to be ready to load his mules, and carried them back to their places, but they did not miss what 'Ali Baba had taken away before. Then holding a council, and deliberating upon this occurrence, they guessed that Kasim, when he was in, could not get out again, but could not imagine how he had learned the secret words by which alone he could enter. So to terrify any person who should attempt the same thing, they cut Kasim's body into four quarters and hung two on one side, and two on the other, within the door of the cave. Then they mounted their horses, and went to beat the roads again, and to attack the caravans they might meet In the meantime, Kasim's wife was very uneasy, when night came, and her husband was not returned. She ran to *Ali Baba in great alarm, and said: "I believe, brother-in-law, that you know Kasim is gone to the forest, and upon what account; it is now night, and he has not returned; I am afraid some misfortune has happened to him." So after midnight, 'Ali Baba departed with his three asses, and went to the forest, and when he came near the rock, having seen neither his brother nor the mules in his way, was alarmed at finding some blood spilt near the door, which he took for an ill omen; but when he had pronounced the word, and the door had opened, he was struck with horror at the dismal sight of his brother's body. He went into the cave, however, to find something to enshroud the remains; and having loaded one of his asses with them, covered them over with wood. The other two asses he loaded with bags of gold, covering them with wood also as before; and then bidding the door shut, came away. When he came home, he drove the two asses loaded with gold into his yard, and left the care of unloading them to his wife, while he led the other to his sister-in-law's house.
There he knocked at the door, which was opened by Marjaneh, a clever slave-girl, who was fruitful in inventions to meet the most difficult circumstances. When he came into the court, he unloaded the ass, and taking Marjaneh aside, said to her: "You must observe an inviolable secrecy.
Your master's body is contained in these two panniers. We must bury him as if he had died a natural death. Go now and tell your mistress. I leave the matter to your wit and skilful devices".
Marjaneh went out early the next morning to a druggist, and asked for a sort of lozenge which was considered efficacious in the most dangerous disorders. The apothecary inquired who was ill. She replied, with a sigh: "Her good master Kasim himself; and that he could neither eat nor speak." In the evening Marjaneh went to the same druggist's again, and with tears in her eyes, asked for an essence which they used to give to sick people only when at the last extremity. "Alas!" said she, taking it from the apothecary, "I am afraid that this remedy will have no better effect than the lozenges, and that I shall lose my good master".
