Marcos was thrown so hard and so far that he fell on his head and shoulder three feet in front of the horse. It was the narrowest place in the whole road, and the knowledge of this flashed through Marcos' mind as he fell. He struck one of the white stones that mark the boundary of the road, and heard his collar-bone snap like a dry stick. Then he rolled over the edge of the precipice into the blackness filled by the roar of the river. He still had one hand whole and ready, though the skin was scraped from it, and the fingers of this hand were firmly twisted into the bridle. He hung for a moment jerked hither and thither by the efforts of the horse to pick himself up on the road above. A stronger jerk lifted him to the edge of the road, and Marcos, hanging there for an instant, found an insecure foothold for one foot in the root of an overhanging bush. But the horse was nearer to the edge now; he was half over and might fall at any moment. It flashed through Marcos' mind that he must live at all costs. There was no one to care for Juanita in the troubled times that were coming. Juanita was his only thought. And he fought for his life with skill and that quickness of perception which is the real secret of success in human affairs. He jerked on the bridle with all the strength of his iron muscle; jerked himself up on the road and the horse over into the gorge. As the horse fell it lashed out wildly; its hind foot touched the back of Marcos' head and seemed almost to break his spine. He rolled over on his side, choking. He did not lose consciousness at once, but knew that oblivion was coming. Perro, the dog, had been excitedly skirmishing round, keeping clear of the horse's heels and doing little else. He now looked over after the horse and Marcos saw his lean body outlined against the sky. He had let the reins go and found that he was grasping a stone in his bleeding fingers instead. He threw the stone at Perro and hit him. The surprised yelp was the last sound he heard as the night of unconsciousness closed over him. Juanita had gone to bed very tired. She slept the profound sleep of youth and physical fatigue for an hour. In the ordinary way she would have slept thus all night. But at midnight she found herself wide-awake again. The first fatigue of the body was past, and the busy mind asserted its rights again. She was not conscious of having anything to think about. But the moment she was half awake the thoughts leapt into her mind and awoke her completely.
