pigeon-post and stay there till eventide whilst the forty slaves stood on guard at the Khan; and when darkness came on they loosed the forty dogs that they might keep watch over the place by night. Such were the doings of Dalilah the Wily One in Baghdad and much like them were The Adventures of Mercury Ali of Cairo.[FN#214] Now as regards the works of Mercury ’Alí; there lived once at Cairo,[FN#215] in the days of Saláh the Egyptian, who was Chief of the Cairo Police and had forty men under him, a sharper named Ali, for whom the Master of Police used to set snares and think that he had fallen therein; but, when they sought for him, they found that he had fled like zaybak, or quicksilver, wherefore they dubbed him Ali Zaybak or Mercury Ali of Cairo. Now one day, as he sat with his men in his hall, his heart became heavy within him and his breast was straitened. The hall-keeper saw him sitting with frowning face and said to him, “What aileth thee, O my Chief? If thy breast be straitened take a turn in the streets of Cairo, for assuredly walking in her markets will do away with thy irk.” So he rose up and went out and threaded the streets awhile, but only increased in cark and care. Presently, he came to a wine-shop and said to himself, “I will go in and drink myself drunken.” So he entered and seeing seven rows of people in the shop, said, “Harkye, taverner! I will not sit except by myself.” Accordingly, the vintner placed him in a chamber alone and set strong pure wine before him whereof he drank till he lost his senses. Then he sallied forth again and walked till he came to the road called Red, whilst the people left the street clear before him, out of fear of him. Presently, he turned and saw a water-carrier trudging along, with his skin and gugglet, crying out and saying, “O exchange! There is no drink but what raisins make, there is no love-delight but what of the lover we take and none sitteth in the place of honour save the sensible freke[FN#216]!” So he said to him, “Here, give me to drink!” The water-carrier looked at him and gave him the gugglet which he took and gazing into it, shook it up and lastly poured it out on the ground. Asked the water-carrier, “Why dost thou not drink?”; and he answered, saying, “Give me to drink.” So the man filled the cup a second time and he took it and shook it and emptied it on the ground; and thus he did a third time. Quoth the water-carrier, “An thou wilt not drink, I will be off.” And Ali said, “Give me to drink.” So he filled the cup a fourth time and gave it to him; and he drank and gave the man a dinar. The water-carrier looked at him with disdain and said, belittling him, “Good luck to thee! Good luck to thee, my lad! Little folk are one thing and great folk another!”——And Shahrazad perceived the dawn of day and ceased saying her permitted say, When it was the Seven Hundred and Ninth Night,
