The History of Caliph Stork by Wilhelm Hauff

Scarcely, on the next morning, had the Caliph Chasid breakfasted and dressed himself, when the Grand-Vizier appeared, to accompany him, as he had commanded, on his walk. The Caliph placed the box with the magic powder in his girdle, and having commanded his train to remain behind, set out, all alone with Mansor, upon their expedition. They went at first through the extensive gardens of the Caliph, but looked around in vain for some living thing, in order to make their strange experiment. The Vizier finally proposed to go farther on, to a pond, where he had often before seen many storks, which, by their grave behavior and clattering, had always excited his attention. The Caliph approved of the proposition of his Vizier, and went with him to the pond. When they reached it they saw a stork walking gravely to and fro, seeking for frogs, and now and then clattering at something before her. Presently they saw, too, another stork hovering far up in the air.

"I will wager my beard, most worthy sire," exclaimed the Grand-Vizier, "that these two long-feet are even now carrying on a fine conversation with one another. How would it be, if we should become storks?"
