The Salt Merchant and His Ass

A PEDDLER drove his Ass to the seashore to buy salt. His road home lay
across a stream into which his Ass, making a false step, fell by
accident and rose up again with his load considerably lighter, as the
water melted the sack. The Peddler retraced his steps and refilled his
panniers with a larger quantity of salt than before. When he came again
to the stream, the Ass fell down on purpose in the same spot, and,
regaining his feet with the weight of his load much diminished, brayed
triumphantly as if he had obtained what he desired. The Peddler saw
through his trick and drove him for the third time to the coast, where
he bought a cargo of sponges instead of salt. The Ass, again playing
the fool, fell down on purpose when he reached the stream, but the
sponges became swollen with water, greatly increasing his load. And
thus his trick recoiled on him, for he now carried on his back a double
burden.
