There once lived in a town of Persia two brothers, one named Cassim, and the other Ali Baba. Their father divided a small inheritance equally between them. Cassim married a very rich wife, and became a wealthy merchant. Ali Baba married a woman as poor as himself, and lived by cutting wood, and bringing it upon three asses into the town to sell. One day, when Ali Baba was in the forest, and had just cut wood enough to load his asses, he saw at a distance a great cloud of dust, which seemed to approach him. He observed it with attention, and distinguished soon after a body of horsemen, whom he suspected might be robbers. He determined to leave his asses to save himself. He climbed up a large tree, planted on a high rock, whose branches were thick enough to conceal him, and yet enabled him to see all that passed without being discovered. The troop, who were to the number of forty, all well mounted and armed, came to the foot of the rock on which the tree stood, and there dismounted. Every man unbridled his horse, tied him to some shrub, and hung about his neck a bag of corn which they brought behind them. Then each of them took off his saddle-bag, which seemed to Ali Baba to be full of gold and silver from its weight. One, whom he took to be their captain, came under the tree in which Ali Baba was concealed; and, making his way through some shrubs, pronounced these words--"Open, Sesame!" As soon as the captain of the robbers had thus spoken, a door opened in the rock; and after he had made all his troop enter before him, he followed them, when the door shut again of itself. The robbers stayed some time within the rock, during which Ali Baba, fearful of being caught, remained in the tree. At last the door opened again, and as the captain went in last, so he came out first, and stood to see them all pass by him; when Ali Baba heard him make the door close by pronouncing these words, "Shut, Sesame!" Every man at once went and bridled his horse, fastened his wallet, and mounted again. When the captain saw them all ready, he put himself at their head, and they returned the way they had come. Ali Baba followed them with his eyes as far as he could see them, and afterward stayed a considerable time before he descended. Remembering the words the captain of the robbers used to cause the door to open and shut, he had the curiosity to try if his pronouncing them would have the same effect. Accordingly, he went among the shrubs, and perceiving the door concealed behind them, stood before it and said, "Open, Sesame!" The door instantly flew wide open.
