"At the age of six Skipper went on the force. Clean of limb and sound of wind he was, with not a blemish from the tip of his black tail to the end of his crinkly forelock. He had been broken to saddle by a Green Mountain boy who knew more of horse nature than of the trashy things writ in books. He gave Skipper kind words and an occasional friendly pat on the flank. So Skipper's disposition was sweet and his nature a trusting one."
