There was an instant volcanic upheaval. The Indian, startled, leaped back. Jack was upon him like a wildcat. They struggled, their bodies so close that the Kiowa could not use his rifle. The Texan had a double advantage, that of surprise and of a more muscular body. Moreover, the redskin made the mistake of trying to cling to his gun. He was flung down to the ground hard, the white man on top of him. Jack became aware that the Indian was going to shout, and knew that if he did all was lost. His strong, brown fingers closed on the throat of the brave. There was a wild thrashing of limbs in a struggle to escape. The grip tightened, cut off a gurgle of escaping air. The naked arms and legs jerked more feebly.... When Roberts crept away into the darkness he carried with him the knife of the Kiowa. The rifle would only have hampered him, since he had to travel fast and light. With every yard gained now he was nearer safety. He knew he was leaving the camp behind. Presently he rose to his feet and traveled faster. For the safety of the two on the island depended upon the speed with which he covered the distance between him and Tascosa. The plainsman seldom walks. His high-heeled boots would be torture on a long tramp. When he wants to reach a place, he rides on horseback. Jack had not walked five miles at a time within a dozen years. Now his long legs reached for the ground in a steady stride that ate up the leagues. He guided his course by the stars until he struck the river far above the camp. Once he stopped for a drink, but the thought of Ridley on the island drove his tired limbs on. Heel and toe, heel and toe, the steady march continued, till the Ranger, lithe and strong though the wind and sun and outdoor life had made him, was ready to drop with fatigue. His feet, pushed forward in the boots by the height of the heels, burned as with fire from the pain of outraged flesh rubbing against stiff leather. But it was not in him to quit. He set his teeth in his exhaustion and ploughed on up the trail. At last he saw the far, faint lights of Tascosa. The last mile or two were interminable, but he walked into the Bird Cage just as the clock on the wall was striking three. The music had started for a dance. A girl in a spangled dress ran up to him. "Come on. Let's dance," she cried; then stopped and looked at him in surprise: "What's the matter with you?" The Ranger climbed up on the bar and beat upon it with the heel of his boot. The dancers stopped in their tracks as the music died. "The Kiowas are on the warpath. They've got two white men trapped on the big island below the bend. Gather all the horses, guns, and men you can. We start in twenty minutes."
