me up in this vase of copper, and he put on the leaden cover his seal, which is enchantment enough to prevent my coming out. Then he had the vase thrown into the sea. During the first period of my captivity I vowed that if anyone should free me before a hundred years were passed, I would make him rich even after his death. But that century passed, and no one freed me. In the second century I vowed that I would give all the treasures in the world to my deliverer; but he never came.

"In the third, I promised to make him a king, to be always near him, and to grant him three wishes every day; but that century passed away as the other two had done, and I remained in the same plight. At last I grew angry at being captive for so long, and I vowed that if anyone would release me I would kill him at once, and would only allow him to choose in what manner he should die. So you see, as you have freed me to-day, choose in what way you will die."

The fisherman was very unhappy. "What an unlucky man I am to have freed you! I implore you to spare my life."

"I have told you," said the genius, "that it is impossible. Choose quickly; you are wasting time."

The fisherman began to devise a plot.

"Since I must die," he said, "before I choose the manner of my death, I conjure you on your honour to tell me if you really were in that vase?"

"Yes, I was" answered the genius.

"I really cannot believe it," said the fisherman. "That vase could not contain one of your feet even, and how could your whole body go in? I cannot believe it unless I see you do the thing."

Then the genius began to change himself into smoke, which, as before, spread over the sea and the shore, and which, then collecting itself together, began to go back into the vase slowly and evenly till there was nothing left outside. Then a voice came from the vase which said to the fisherman, "Well, unbelieving fisherman, here I am in the vase; do you believe me now?"

The fisherman instead of answering took the lid of lead and shut it down quickly on the vase.

"Now, O genius," he cried, "ask pardon of me, and choose by what death you will die! But no, it will be better if I throw you into the sea whence I drew you out, and I will build a house on the shore to warn fishermen who come to cast their nets here, against fishing up such a wicked genius as you are, who vows to kill the man who frees you."

At these words the genius did all he could to get out, but he could not, because of the enchantment of the lid.

Then he tried to get out by cunning.

"If you will take off the cover," he said, "I will repay you."

"No," answered the fisherman, "if I trust myself to you I am afraid you will treat me as a certain Greek king treated the physician Douban. Listen, and I will tell you."

The Story of the Greek King and the Physician Douban

In the country of Zouman, in Persia, there lived a Greek king. This king was a leper, and all his doctors had been unable to cure him, when a very clever physician came to his court.

He was very learned in all languages, and knew a great deal about herbs and medicines.

As soon as he was told of the king's illness he put on his best robe and presented himself before the king. "Sire," said he, "I know that no physician has been able to cure your majesty, but if you will follow my instructions, I will promise to cure you without any medicines or outward application."

The king listened to this proposal.

"If you are clever enough to do this," he said, "I promise to make you and your descendants rich for ever."

The physician went to his house and made a polo club, the handle of which he hollowed out, and put in it the drug he wished to use. Then he made a ball, and with these things he went the next day to the king.

He told him that he wished him to play at polo. Accordingly the king mounted his horse and went into the place where he played.
