As the muleteer had sold all his wares he was indulging in a sleep, and had it not been for the dog-flies that teased the mules they would also have slept.

Juan let the muleteer pass; but as the last mule came up he seized it, and, taking off its trappings, and disencumbering it of its ponderous albarda, or saddle, he freed the animal on the roadside, and replaced the trappings and the saddle on himself.

His companions were not slow in seizing the prize and hurrying away with it, while Juan Rivas continued for some distance along the road, following in the train of mules.

As soon as he considered that his companions would be out of sight, he commenced backing with all his strength, which brought the mules to a sudden halt and caused their bells to tinkle.

The muleteer looked back to see if anything was wrong, but, perceiving nothing, bestowed a hearty blow on his mule, and on he went again.

The student now began to rear and jump about so that the muleteer pulled up, and, having dismounted, proceeded to inquire into the cause of the mule so misbehaving itself; but his astonishment was great when, instead of a mule, he saw a human being bearing the trappings and the saddle.

“What merry freak is this,” demanded the muleteer, addressing the student, “that I see you replacing my mule?”

“It is no merry freak, indeed it is not,” replied Juan Rivas, “but a sad reality. You see before you, good master, a poor, miserable creature, who for his many offences against Mother Church was transformed into a mule, and sentenced to remain so for a number of years. My term of punishment has just expired, and I am restored to my natural form.”

“But where is my mule that cost me one hundred crowns not many years ago?” asked the muleteer.

“You do not understand me, good master,” replied the student. “I was the mule, and the mule was I; now I am I. When you used to kick your mule, you really kicked me; when you fed it, you fed me; and now, when you speak to me, you speak to all that remains of your mule. Now do you understand?”
