The night passed restlessly. He saw the first rays of dawn break over the range and creep farther and farther down the valley, throwing a pale pink over the landscape and sending gaunt shadows slinking off into the light. A whinny from Pat aroused him. He arose painfully, gazed at the man at his feet, and then turned his eyes toward the distant horizon. A second whinny disturbed him and he shifted his gaze. Far above two great buzzards, circling round and round, faded into the morning haze. From a neighboring sand-dune a jack-rabbit appeared, paused a quivering moment, then scurried from view. The morning light grew brighter. A third whinny, and Pat now slowly started toward him. But again he fastened his eyes upon the distant horizon, hoping for a sight of the ranch wagon. But no wagon appeared. At length he turned to the horse. Pat stood soberly regarding the man, his ears forward, head drooping, tail motionless, as if recognizing in this mute object an erstwhile master. And suddenly lifting his head, he sounded a soft nicker, tremulously. Then again he fell to regarding the still form with strange interest. The form was still, still for all eternity. For the man was dead. Stephen sat down. He was shaking with fever and weakness. He placed a handkerchief over the face in repose, almost relieved that peace had come to this troubled soul. Then he thought of possible action. He realized that he was utterly lost. He had Pat, and for this he was thankful, since he knew that he could at least mount the horse and leave him to find a way out. But the horse alone must do it. He himself was bewildered, for the desert in broad day, as much as in the long night, revealed nothing. On every hand it lay barren, destitute of movement, wrapped in silence, seeming to mock his predicament. Yet he could not bring himself to mount at once. He sat motionless, suffering acutely, knowing that the least exertion would increase his pain--a machine run down--not caring to move. Suddenly, off to the east appeared a horse--a gray. It cantered majestically to the top of a dune, and stood there--head erect, nostrils quivering, ears alert, cresting the hillock like a statue. Stephen shivered. For instinctively he knew this to be the gray stallion, the cross-bred, that had trampled the form beside him. His first impulse was to mount Pat and spur him in a race for life; his second impulse was to crouch in hiding in the hope of escaping the keen scrutiny of that merciless demon. He chose the race. Springing to his feet, he leaped for Pat, and he grasped the saddle-horn. In his haste he slipped, lost his stirrup, and fell back headlong. The shock made him faint, and for a time he was unconscious. Shrill neighing aroused him, and, hastily gaining his feet, he saw Pat running lightly, well-contained, to meet the swiftly advancing gray stallion. Then events moved with a terrible unreality.
