Then said she:--I have heard, O auspicious King, that Peri-Banu said further to Prince Ahmad, "Natheless I will grant this largesse also as the Sultan hath set his mind upon it, and no harm shall come therefrom to me or to thee, albe 'tis a matter of great risk and danger, and it is prompted by not a little of malice and ungraciousness. But give careful heed to my words, nor neglect thou aught of them, or thy destruction is certain-sure. I now will tell thee what to do. In the hall of yonder castle which riseth on that mountain is a fountain sentinelled by four lions fierce and ravening; and they watch and ward the path that leadeth thereto, a pair standing on guard whilst the other two take their turn to rest, and thus no living thing hath power to pass by them. Yet will I make known to thee the means whereby thou mayest win thy wish without any hurt or harm befalling thee from the furious beasts." Thus saying she drew from an ivory box a clew of thread and, by means of a needle one of those wherewith she had been plying her work, made thereof a ball. This she placed in the hands of her husband, and said, "First, be thou careful that thou keep about thee with all diligence this ball, whose use I shall presently explain to thee. Secondly, choose for thyself two horses of great speed, one for thine own riding, whilst on the other thou shalt load the carcass of a freshly slaughtered sheep cut into four quarters.

At this moment thou shalt see the four lions; and the two that wake and watch will rouse the twain that sleep and rest. All four will turn their jaws to the ground and growl and roar with hideous howlings, and make as though about to fall upon thee and tear thee limb from limb. However, fear not nor be dismayed, but ride boldly on and throw to the ground from off the led-horse the sheep's quarters, one to each lion. See that thou alight not from thy steed, but gore his ribs with thy shovel stirrup[FN#344] and ride with all thy might and main up to the basin which gathereth the water. Here dismount and fill the phial whilst the lions will be busied eating. Lastly, return with all speed and the beasts will not prevent thy passing by them." Next day, at peep of morn, Prince Ahmad did according to all that Peri-Banu had bidden him and rode forth to the castle. Then, having passed through the
