The prince answered, 'I know not, madam, whether you be in jest or no; but for my own part I seriously declare, before these ladies your sisters, that from this moment I heartily accept your offer, as my lady and mistress. Nor will I pretend to have any power over your actions.' At these words my sisters changed colour, and I could perceive afterwards that they did not love me as formerly.

We had come into the Persian Gulf, not far from Balsora, where I hoped, considering the fair wind, we might arrive the day following; but in the night, when I was asleep, my sisters watched their time and threw me overboard. They did the same to the prince, who was drowned. I swam for some minutes in the water; but by good fortune, or rather miracle, I soon felt ground. I went towards a black place, that, so far as I could discern in the dark, seemed to be land, and actually was a flat on the coast. When day came, I found it to be a desert island, lying about twenty miles from Balsora. I soon dried my clothes in the sun; and as I walked along I found several sorts of fruit, and likewise fresh water, which gave me some hope of preserving my life.

I laid myself down in the shade and soon after I saw a winged serpent, very large and long, coming towards me, wriggling to the right and to the left, and hanging out his tongue, which made me think he was ill. I arose, and saw a larger serpent following him, holding him by the tail, and endeavouring to devour him. I had compassion on him, and instead of flying away, I had the boldness and courage to take up a stone that by chance lay by me, and threw it with all my strength at the great serpent, whom I hit on the head, and killed him. The other, finding himself at liberty, took to his wings and flew away. I looked a long while after him in the air, as an extraordinary thing; but he flew out of sight, and I lay down again in another place in the shade, and fell asleep.

When I awoke, judge how surprised I was to see by me a black woman, of lively and agreeable looks, who held, tied together in her hand, two dogs of the same colour. I sat up and asked her who she was. 'I am,' said she, 'the serpent whom you delivered not long since from my mortal enemy. I knew not how to acknowledge the great kindness you did me, but by doing what I have done. I knew the treachery of your sisters, and, to revenge you on them, as soon as I was set at liberty by your generous assistance I called several of my companions together, fairies like myself. We have carried into your storehouses at Bagdad all your lading that was in your vessel, and afterwards sunk it.

'These two black dogs are your sisters, whom I have transformed into this shape. But this punishment is not sufficient; for I will have you treat them after such a manner as I shall direct.'

At those words the fairy took me fast under one of her arms, and the two dogs in the other, and carried me to my house in Bagdad, where I found in my storehouses all the riches which were laden on board my vessel. Before she left me she delivered the two dogs, and told me, 'If you will not be changed into a dog as they are, I order you to give each of your sisters every night a hundred lashes with a rod, for the punishment of the crime they have committed against your person and the young prince whom they drowned.' I was forced to promise that I would obey her order. For many months I whipped them every night, though with regret. I gave evidence by my tears with how much sorrow and reluctance I must perform this cruel duty.

Now the fairy had left with me a bundle of hair, saying withal that her presence would one day be of use to me; and then, if I only burnt two tufts of this hair, she would be with me in a moment, though she were beyond Mount Caucasus.

Desirous at length to see the fairy and beg her to restore the two black dogs, my sisters, to their proper shape, I caused fire one day to be brought in, and threw the whole bundle of hair into it. The house began to shake at that very instant, and the fairy appeared in the form of a lady very richly dressed.

I besought her, with every form of entreaty I could employ, to restore my sisters to their natural shape, and to release me from the cruel duty that I had always unwillingly performed.

The fairy at length consented, and desired a bowl of water to be brought; she pronounced over it some words which I did not understand, and then sprinkled the water upon the dogs. They immediately became two ladies of surprising beauty, and I recognised in them the sisters to whose human form I had so long been a stranger. They soon after married the sons of kings, and lived happily for the rest of their lives.
