For a moment the mule hung his head in a dejected manner, as though thinking out some new plan. Suddenly his meditations were interrupted by a yell directly in one of his long ears, and a sharp pain felt in both sides at once. He sprang forward to escape these annoyances; but they clung to him as close as did his new rider. Faster and faster he flew, while harder and harder spurred Glen, and louder grew his yells. All at once the animal stopped, as short as on the former occasion; but this time the rider did not fly over his head. The fact is, the mule was now so thoroughly frightened and bewildered that he had no idea of stopping until his lower jaw was jerked back so sharply that had it belonged to any other kind of an animal it must have been dislocated. Even Glen had no idea of the power of that cruel Mexican bit, and was almost as greatly surprised as the mule at its sudden effect.
