Each time one donkey transported salt through the ditch, he reached the middle and lay down in the water. All the salt floated away with the water, so the donkey walked light the rest of the way.
The owner noticed this and decided to teach the donkey a lesson. He loaded it with cotton and sent it through the ditch. The donkey, as usual, reached the middle, and there he lay down in the water. The cotton got wet and instead of five mana it began to weigh twenty.
From then on, the donkey never went into the water.
