A carrier on his way to a market town had to stop at some houses by the roadside, in the way of his business, leaving his cart and horse upon the public road, under the protection of a passenger and a trusty dog. Upon his return he missed one of the women passengers, and likewise a led horse which was owned by a gentleman of the neighborhood. The horse he was taking along, tied to the end of the cart. On inquiry he found out that during his absence, the woman, who had been anxious to try the mettle of the pony, had mounted it, and the animal had set off at full speed. The carrier expressed much anxiety for the safety of the young woman, casting at the same time an expressive look at his dog. Oscar observed his master's eye, and aware of its meaning, instantly set off in pursuit of the pony. Coming up with it soon after, he made a sudden spring, seized the bridle, and held the animal fast. Several people, having seen his actions, and the dangerous situation of the girl, hastened to her aid. Oscar, however, notwithstanding their repeated endeavors, would not let go his hold, and the pony was actually led into the stable with the dog still clinging to it. When the carrier entered the stable, Oscar wagged his tail in token of his satisfaction, and at once gave up the bridle to his master.
