The learned Selim soon arrived. 'Selim,' said the Caliph to him, 'Selim, it is said thou art very learned. Just look at this writing whether thou canst read it; if thou canst read it, thou gettest a new robe of honour from me; if thou canst not, thou gettest twelve boxes on the ears and twenty-five lashes on the soles of thy feet, for having been called Selim the learned without cause.' Selim bowed and said: 'Thy will be done, O Master!' For a long time he looked at the writing; suddenly, however, he exclaimed: 'That is Latin, O Master, or let me be hung!' 'Say what it means,' demanded the Caliph, 'if it is Latin.' Selim began to translate: 'Man who findeth this, praise Allah for his goodness. He who takes a pinch of this powder in this box and therewith says "Mutabor," can change himself into any animal, and also understand the language of animals. If he afterwards wish to resume his human form, let him bow thrice to the East and say the same word. But beware when thou art changed that thou laughest not, or the magic word will depart from thy memory for ever, and thou remainest a beast.' When Selim the learned had read this, the Caliph was pleased beyond measure. He made the learned man swear not to reveal the secret to any one, presented him with a splendid robe, and dismissed him. Then turning to his Grand Vizier he said: 'This I call making a bargain, Mansor! How glad I am at being able to become an animal! Come to me to-morrow morning. We will then go together into the fields, take a pinch out of the box, and then listen to what is said in the air and the water, in wood and field.' Next morning, scarcely had the Caliph Chasid breakfasted and dressed himself, when the Grand Vizier appeared as ordered, to accompany him on his walk. The Caliph put the box with the magic powder in his girdle, and having ordered his suite to remain behind, he and the Grand Vizier set out alone on the journey. They first passed through the large gardens of the Caliph, but looked in vain for any living thing on which to try the experiment. The Vizier at last proposed to pursue their journey to a pond, where he had often seen many animals, especially storks, whose grave manners and clappings had always excited his attention. The Caliph approved of the Vizier's proposal, and went with him towards the pond. Having arrived there, they saw a stork soberly pacing up and down looking for frogs, and chattering something now and then to itself. At the same moment they saw far up in the sky another stork hovering in this direction. 'I wager my beard, most gracious Master,' said the Grand Vizier, 'this long-legged pair are now having a pleasant talk. How would it be if we turned into storks?' 'Wisely spoken,' replied the Caliph. 'But first, let us consider how we may become men again. It is easy enough! If we bow thrice to the East, and say Mutabor, I shall be Caliph and thou Vizier. But for heaven's sake no laughing, or we are lost.'
