Horseback exercise is a curious thing, certainly, in some of its effects. When Robert was afoot that morning several things had combined, as we have seen, to make him gloomy, despondent, and generally out of sorts. Ewing's backsliding had annoyed him, and the possibility or probability of Phil's accuracy of information and judgment in the matter of Cousin Sudie and Dr. Harrison had depressed him sorely. When he found himself on the back of this magnificent colt, whose delight it was to carry a strong, fearless rider, he fell immediately into hearty sympathy with the high spirits and bounding pulses of the animal. He struck out into a gallop, and in an instant felt himself in a far brighter world than that which he had been traversing ten minutes since. His spirits rose. His hopefulness returned. The world became better and the future more promising. Mr. Robert Pagebrook felt the unreasonable but thoroughly delightful exhilaration to which Billy Barksdale referred when he said, "Bob is the happiest fellow in the world; he gets glad sometimes just because he is alive." That was precisely the state of affairs. Mr. Robert on this high-mettled horse was superlatively alive, and was glad because of it. There is more of joy than many people know in the mere act of living; but it is only they who have clear consciences, springy muscles, and perfect health of both mind and body who fully share this joy. Robert Pagebrook had all of these, and was astride a perfect horse to boot; and that, as all horsemen know, is an important element in the matter. He galloped on toward The Oaks, leaving his troubles just where he mounted his horse. He forgot Ewing's apostasy; he forgot Dr. Harrison, but he remembered Cousin Sudie, and that right pleasantly too. Naturally enough, being on horseback, he projected himself into the future, which is always a bright world when one is galloping toward it. He would heartily enjoy the coming fox-chase--particularly on such an animal as that now under him. Then his thoughts pushed themselves still further forward, and he dreamed dreams. His full professorship would pay him a salary sufficient to justify him in setting up a little establishment of his own, and he should then know what it was to have a home in which there should be love and purity and peace and domestic comfort. The woman who was to form the center of all this bliss was vaguely undefined as to identity and other details. She existed only in outline, in the picture, but that outline strikingly resembled the young woman who carried the key-basket at Shirley--an accidental resemblance, of course, for Mr. Robert Pagebrook was positive that he was not in love with Cousin Sudie.
