Half way down, the earth began to slip. Patricia, looking up and over her shoulder, uttered a cry. A great boulder, imbedded in the earth directly above them, was dislodging itself, was falling! At her cry Landless raised his eyes, saw the threatening mass, caught her around the waist, and with one supreme effort swung her out of the path of the avalanche which descended the next moment, bearing him with it to the ground beneath. He was recalled to consciousness by the dash of water against his face, and opened his eyes to behold Patricia bending over him, very white, with tragic eyes, and lips pressed closely together. She had run to the river, flowing through the sunshine a hundred yards away, for water, which she had brought back in his cap, and she had taken the kerchief from her neck, wet it, and laid it upon his forehead. Her hands were torn and bleeding. He saw them and uttered an exclamation. "It is nothing," she said; "I had to move the rock." Scarcely fully conscious as yet, his eyes glanced from her to the great rock which lay upon one side, and upon which there were bloodstains. "I have had a bad fall," he said unsteadily, but with an attempt to speak lightly because of the trouble in her eyes, "but it is over. Come! we must hurry on. We have no time to lose." As he spoke he strove to rise, but with the effort came a pang of anguish, and he sank back, faint and sick, upon the ground. "Ah! you cannot!" cried Patricia with a great sob in her voice. "It is your foot. The rock fell upon it." After a moment of lying with closed eyes, he sat up and with his knife began to cut away the moccasin from the wounded limb. Presently he looked up. "Yes, it is badly crushed. There is no doing anything with it." For many moments they gazed at each other in a despairing silence, broken by Patricia's low, "What are we to do now?" "We must go on," answered Landless. "It is death to stay here." Holding by the bank against which he had leaned, he dragged himself up and stood for an instant with eyes dark with pain; then, setting his lips, took a step forward. The bronze of his face paled, and beads of anguish stood upon his brow, but he took another step. Patricia, the tears running down her cheeks, came to him and put his arm around her shoulder. "I will be your crutch," she said, striving to smile. "I will carry the gun, too."
