At about the time that Chavis and Kester had discovered Ruth's pony and had clambered up the slope in search of the girl, the two figures on the timber-fringed level near the break in the canyon wall were making grotesque shadows as they danced about in the dying sunlight. Masten's science had served him well. He had been able, so far, to evade many of Randerson's heavy blows, but some of them had landed. They had hurt, too, and had taken some of the vigor out of their target, though Masten was still elusive as he circled, with feet that dragged a little, feinting and probing for openings through which he might drive his fists. A great many of his blows had reached their mark also. Randerson's face was covered with livid lumps and welts. But he seemed not to mind them, to be unconscious of them, for on his lips was still the dogged smile that had reached them soon after the fight had started, and in his eyes was the same look of cold deliberation and unrelenting purpose. He had spoken no word since the fight began; he had taken Masten's heaviest punches without sign or sound to indicate that they had landed, always crowding forward, carrying the battle to his adversary, refusing to yield a step when to yield meant to evade punishment. Passion, deep and gripping, had made him for the moment an insensate automaton; he was devoid of any feeling except a consuming desire to punish the despoiler of his "kid." But he was holding this passion in check; he was its master--it had not mastered him; he had made it a vassal to his deliberation. To have unleashed it all at once would have made him too eager, would have weakened him. He had chosen this punishment for Masten, and he would see that it was sufficient. But, as Randerson had well known, Masten was no mean opponent. He stepped in and out rapidly, his blows lacking something in force through his inability to set himself. But he landed more often than Randerson; he blocked and covered cleverly; he ducked blows that would have ended the fight had they struck him with their full force. Masten had been full of confidence when the fight started. Some of that confidence had gone now. He was beginning to realize that he could not beat Randerson with jabs and stinging counters that hurt without deadening the flesh where they struck; nor could he hope to wear the Westerner down and finally finish him. And with this realization came a pulse of fear. He began to take more risks, to set himself more firmly on his feet in order to give his blows greater force when they landed. For he felt his own strength waning, and he knew what the end would be, should he no longer be able to hold Randerson off.
