in gaol ye number thirty-seven souls; so I will stow you away armed and accoutred each within his jar and will load two upon each mule, and upon the nineteenth mule there shall be a man in an empty jar on one side, and on the other the jar full of oil.  I for my part, in guise of an oil-merchant, will drive the mules into the town, arriving at the house by night, and will ask permission of its master to tarry there until morning.  After this we shall seek occasion during the dark hours to rise up and fall upon him and slay him.”  Furthermore the Captain spake saying, “When we have made an end of him we shall recover the gold and treasure whereof he robbed us and bring it back upon the mules.”  This counsel pleased the robbers who went forthwith and purchased mules and huge leathern jars, and did as the Captain had bidden them.  And after a delay of three days shortly before nightfall they arose; and over smearing all the jars with oil of mustard, each hid him inside an empty vessel.  The Chief then disguised himself in trader’s gear and placed the jars upon the nineteen mules; to wit, the thirty-seven vessels in each of which lay a robber armed and accoutred, and the one that was full of oil.  This done, he drove the beasts before him and presently he reached Ali Baba’s place at nightfall; when it chanced that the house-master was strolling after supper to and fro in front of his home.  The Captain saluted him with the salam and said, “I come from such and such a village with oil; and ofttimes have I been here a selling oil, but now to my grief I have arrived too late and I am sore troubled and perplexed as to where I shall spend the night.  An thou have pity on me I pray thee grant that I tarry here in thy court yard and ease the mules by taking down the jars and giving the beasts somewhat of fodder.”  Albeit Ali Baba had heard the Captain’s voice when perched upon the tree and had seen him enter the cave, yet by reason of the disguise he knew him not for the leader of the thieves, and granted his request with hearty welcome and gave him full license to halt there for the night.  He then pointed out an empty shed wherein to tether the mules and bade one of the slave-boys go fetch grain and water.  He also gave orders to the slave-girl Morgiana saying,” A guest hath come hither and tarrieth here to night.  Do thou busy thyself with all speed about his supper and make ready the guest bed for him.”  Presently, when the Captain had let down all the jars and had fed and watered his mules, Ali Baba received him with all courtesy and kindness, and summoning Morgiana said in his presence, “See thou fail not in service of this our stranger nor suffer him to lack for aught.  To-morrow early I would fare to the Hammam and bathe; so do thou give my slave-boy Abdullah a suit of clean white clothes which I may put on after washing; moreover make thee ready a somewhat of broth overnight that I may drink it after my return home.”  Replied she, “I will have all in readiness as thou hast bidden.”  So Ali Baba retired to his rest, and the Captain, having supped, repaired to the shed and saw that all the mules had their food and drink for the night.—­And as the morn began to dawn Shahrazad held her peace till
