"I'll get him in spite of hell!" CHAPTER XX FIDELITY Meantime Pat was running at top speed across the desert. Yet he was trying to understand this strange call to duty. Roused from fitful slumber by trampling hoofs, he had felt an excited hand jerking him to his feet, and after that a slender rope looped round his lower jaw. Then he had been urged, with a wriggling form on his bare back, frantic heels drumming his sides, and a strange voice impelling him onward past a surging crowd of horsemen, still only half awake, out into the open. When he was well in the fore, he had found himself crowded to his utmost--over sand-dune, into arroyo, across the level--around him thundering hoofs, panting horses, silent men, all speeding forward in the glorious moonlight. It was a strange awakening, yet he had not entertained thoughts of rebellion, despite the fact that he had not liked the flaying rope, the soft digging heels, the absence of bridle and saddle. It was strange; it was not right. None of it had checked up with any item of his experience. Yet, oddly enough, he had not rebelled. Nor was he harboring thoughts of rebellion now. Racing onward, smarting with each swing of the lash, he found himself somehow interested solely in holding his own with the other horses. Suddenly, alert to their movements, he saw a cleft open in their surging ranks, made by the fall of an exhausted horse. Yet the others did not stop. They galloped on, unheeding, though he himself was jerked up. Then followed a swift exchange of words, and then the unhorsed man mounted behind Pat's new master. Carrying a double load now, Pat nevertheless dashed ahead at his former speed, stumbling with his first steps, but soon regaining his stride and overtaking the others. And though it cost him straining effort, he felt rewarded for his pains when one of the men uttered a grunt which he interpreted as approval. But it was all very strange. A canyon loomed up on his left. He had hardly seen the black opening when he was swung toward it. He plunged forward with the other horses, and was the first to enter the canyon's yawning mouth. Between its high walls, however, he found himself troubled by black shadows. Many of them reached across his path like projections of rock, and more than once he faltered in his stride. But after passing through two or three in safety he came at length to understand them and so returned to his wonted self-possession.
