Ali Baba, more out of his natural good temper, than frightened by the insulting menaces of his unnatural brother, told him all he desired, and even the very words he was to use to gain admission into the cave.

Cassim, who wanted no more of Ali Baba, left him, resolving to be beforehand with him, and hoping to get all the treasure to himself.  He rose the next morning, long before the sun, and set out for the forest with ten mules bearing great chests, which he designed to fill; and followed the road which Ali Baba had pointed out to him.  He was not long before he reached the rock, and found out 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, Sesame,” the door immediately opened, and when he was in, closed upon him.  In examining the cave, he was in great admiration to find much more riches than he had apprehended from Ali Baba’s relation.  He was so covetous, and greedy of wealth, that he could have spent the whole day in feasting his eyes with so much treasure, if the thought that he came to carry some away had not hindered him.  He 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 necessary word to make it open, but instead of Sesame, 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.

Cassim had never expected such an incident, and was so alarmed at the danger he was in, that the more he endeavoured to remember the word Sesame, the more his memory was confounded, and he had as much forgotten it as if he had never heard it mentioned.  He threw down the bags he had loaded himself with, and walked distractedly up and down the cave, without having the least regard to the riches that were round him.

About noon the robbers chanced to visit their cave, and at some distance from it saw Cassim’s mules straggling about the rock, with great chests on their backs.  Alarmed at this novelty, they galloped full speed to the cave.  They drove away the mules, which Cassim had neglected to fasten, and they strayed through the forest so far, that they were soon out of sight.  The robbers never gave themselves the trouble to pursue them, being more concerned to know who they belonged to.  And while some of them searched about the rock, the captain and the rest went directly to the door, with their naked sabres in their hands, and pronouncing the proper words, it opened.

Cassim, who heard the noise of the horses’ feet from the middle of the cave, never doubted of the arrival of the robbers, and his approaching death; but was resolved to make one effort to escape from them.  To this end he rushed to the door, and no sooner heard the word Sesame, which he had forgotten, and saw the door open, than he ran out and threw the leader down, but could not escape the other robbers, who with their sabres soon deprived him of life.
