Jack of the Pony Express

"Your father is a little late to-night, isn't he Jack?" "Yes, Mrs. Watson, he should have been here a half-hour ago, and he would, too, if he had ridden Sunger instead of his own horse." "You think a lot of that pony of yours, don't you, Jack?" and a motherly-looking woman came to the doorway of a small cottage and peered up the mountain trail, which ran in front of the building. Out on the trail itself stood a tall, bronzed lad, who was, in fact, about seventeen years of age, but whose robust frame and athletic build made him appear several years older. "Yes, Mrs. Watson," the boy answered with a smile, "I do think a lot of Sunger, and he's worth it, too." "Yes, I guess he is. And he can travel swiftly, too. My goodness! The way you sometimes clatter past my house makes me think you'll sure have an accident. Sometimes I'm so nervous I can't look at you."
