said to Abdallah:  “My son, we are now at the end of our journey.  I shall employ my prayers to obtain from Allah that the earth shall open and make an entrance wide enough to permit thee to descend into a place where thou shalt find one of the greatest treasures that the earth contains.  Hast thou courage to descend into the vault?” Abdallah assured him that he might depend on his fidelity; and then the Dervish lighted a small fire, into which he cast a perfume:  he read and prayed for some minutes, after which the earth opened, and he said to the young man:  “Thou mayest now enter.  Remember that it is in thy power to do me a great service; and that this is perhaps the only opportunity thou shalt ever have of testifying to me that thou art not ungrateful.  Do not let thyself be dazzled by the riches that thou shalt find there:  think only of seizing upon an iron candlestick with twelve branches, which thou shalt find close to the door.  That is absolutely necessary to me:  come up with it at once.”  Abdallah descended, and, neglecting the advice of the Dervish, filled his vest and sleeves with the gold and jewels which he found heaped up in the vault, whereupon the opening by which he had entered closed of itself.  He had, however, sufficient presence of mind to seize the iron candlestick, and endeavoured to find some other means of escape from the vault.  At length he discovers a narrow passage, which he follows until he reaches the surface of the earth, and looking for the Dervish saw him not, but to his surprise found that he was close to his mother’s house.  On showing his wealth to his mother, it all suddenly vanished.  But the candlestick remained.  He lighted one of the branches, upon which a dervish appeared, and after turning round an hour he threw down an asper (about three farthings in value) and vanished.  Next night he put a lighted candle in each of the branches, when twelve dervishes appeared, and having continued their gyrations for an hour each threw down an asper and vanished.  In this way did Abdallah and his mother contrive to live for a time, till at length he resolved to carry the candlestick to the good Dervish, hoping to obtain from him the treasure which he had seen in the vault.  He remembered his name and city, and on reaching his dwelling found the Dervish living in a magnificent palace, with fifty porters at the gate.  The Dervish thus addressed Abdallah:  “Thou art an ungrateful wretch!  Hadst thou known the value of the candlestick thou wouldst never have brought it to me.  I will show thee its true use.”  Then the Dervish placed a light in each branch, whereupon twelve dervishes appeared and began to whirl, but on his giving each a blow with a stick, in an instant they were changed into twelve heaps of sequins, diamonds, and other precious stones.  Ungrateful as Abdallah had shown himself, yet the Dervish gave him two camels laden with gold, and a slave, telling him that he must depart the next morning.  During the night Abdallah stole
