The next morning, while the merchants opened their bales of merchandises, prince Ali, who travelled only for his pleasure, and had brought nothing but necessaries with him, after he had dressed himself, took a walk into that quarter of the town where they sold precious stones, gold and silver works, brocades, silks, fine linens, and other choice and valuable articles, and which was at Sheerauz called the bezestein.  It was a spacious and well-built street, arched over, within the arcades of which were shops.  Prince Ali soon rambled through the bezestein, and with admiration judged of the riches of the place by the prodigious quantities of the most precious merchandises exposed to view.

But among the criers who passed backwards and forwards with several sorts of goods, offering to sell them, he was not a little surprised to see one who held in his hand an ivory tube, of about a foot in length, and about an inch thick, which he cried at forty purses.  At first he thought the crier mad, and to inform himself, went to a shop, and said to the merchant who stood at the door, “Pray, sir, is not that man” (pointing to the crier, who cried the ivory tube at forty purses) “mad?  If he is not, I am much deceived.”  “Indeed, sir,” answered the merchant, “he was in his right senses yesterday; and I can assure you he is one of the ablest criers we have, and the most employed of any, as being to be confided in when any thing valuable is to be sold; and if he cries the ivory tube at forty purses, it must be worth as much or more, on some account or other which does not appear.  He will come by presently, when we will call him, and you shall satisfy yourself:  in the mean time sit down on my sofa, and rest yourself.”

“First, sir,” pursued the crier, presenting the ivory tube to the prince, “observe, that this tube is furnished with a glass at both ends; by looking through one of them, you will see whatever object you wish to behold.”  “I am,” said the prince, “ready to make you all proper reparation for the reflection I have cast upon you, if you can make the truth of what you advance appear; and” (as he had the ivory tube in his hand, after he had looked at the two glasses), he said, “shew
