"Yes; he has not been used enough of late. He'll be quiet before night, for I am enjoying this so much that I should like to return in the same way." "I am delighted to hear you say so. My spirits begin to rise the moment I am with you, and you are the only woman I ever knew from whose side I could not go with the feeling, 'Well, some other time would suit me now.'" Her laugh rang out so suddenly and merrily that her horse sprang into a gallop, but she checked him speedily, and thought, with an exultant thrill, "Graydon now has surely revealed an unmistakable symptom." To him she said: "You amuse me immensely. You are almost as outspoken as little Harry, and, like him, you mistake the impression of the moment for the immutable." "Now, that's not fair to me. I've been constant to you. Own up, Madge, haven't I?" With a glance and smile which she never gave to others, and rarely to him, she said: "I own up. I don't believe a real brother would have been half so nice.". "Let the past guarantee the future, then. Shake hands against all future misunderstandings." She was scarcely ready to shake hands on such a basis, but of course would have complied. In the slight confusion her hand relaxed its grasp on the curb-rein, and at the same moment a locomotive, coming along the side of the opposite mountain, blew a shrill whistle. Instantly her horse had the bit in his teeth, and was off at a furious pace. At first she did not care, but soon found, with anxiety, that he paid no attention to her efforts to check him, and that his pace was passing into a mad run. The gorge was growing narrower, and the lofty mountains stood, with their rocky feet, nearer and nearer together. She could see through the intervening trees that the road and rail-track were becoming closely parallel, and at last realized that her horse was unmanageable. When the engineer of the train saw Madge's desperate riding he surmised that her horse was not under control, and put on extra steam in order to take the exciting cause of the animal's terror out of the way. He thought he could easily reach the summit of the clove where the carriage-drive crossed the track before Madge, and then pass swiftly over the down-grade beyond; but he had not calculated on the terrific speed of the horse; and when at last the track and roadway were almost side by side the frantic beast, with his pale rider, was abreast of the train. For a moment the engineer was irresolute, and then, too late, as he feared, "slowed up." The narrow road, with a precipitous mountain on the left, was so near to the flying train that the passengers in an open car could almost touch Madge, and she was to them like a strange and beautiful apparition, with her white face and large dark eyes filled with an unspeakable dread.
