But then his words chopped squarely off in his throat. The plodding advance commenced again. And the next instant a gray form revealed itself at the edge of the thicket.
It was Graycoat, half-blind with his madness, and desperate in his agony.
There was no more deadly thing in all the hills than he. Even the bite of a rattlesnake would have been welcomed beside his. He stood a long instant, and all his instincts and reflexes that would have ordinarily made him flee in abject terror were thwarted and twisted by the fever of his madness. He stared a moment at the two figures, and his red eyes could not interpret them. They were simply foes, for it was true that when this racking agony was upon him, even lifeless trees seemed foes sometimes. He seemed eerie and unreal as he gazed at them out of his burning eyes; and the white foam gathered at his fangs. And then, wholly without warning, he charged down at them.
He came with unbelievable speed. The elder Lennox cried once in warning and cursed himself for venturing forth on the ridge without a gun. He was fully twenty feet distant from Dan; yet he saw in an instant his only course. This was no time to trust their lives to the marksmanship of an amateur. He sprang towards Dan, intending to wrench the weapon from his hand.
But he didn't achieve his purpose. At the first step his foot caught in a projecting root, and he was shot to his face on the trail. But a long life in the wilderness had developed Lennox's reflexes to an abnormal degree; many crises had taught him muscle and nerve control; and only for a fraction of an instant, a period of time that few instruments are fine enough to measure, did he lie supinely upon the ground. He rolled on, into a position of defense. But he knew now he could not reach the younger man before the mad coyote would be upon them. The matter was out of his hands. Everything depended on the aim and self-control of the tenderfoot.
And at the same instant he wondered, so intensely that all other mental processes were subjugated to it, why he had not heard Dan shoot.
He looked up, and the whole weird picture was thrown upon the retina of his eyes. The coyote was still racing straight toward Dan, a gray demon that in his madness was more terrible than any charging bear or elk. For there is an element of horror about the insane, whether beasts or men, that cannot be denied. Both men felt it, with a chill that seemed to penetrate clear to their hearts. The eyes flamed, the white fangs of Graycoat caught the sunlight. And Dan stood erect in his path, his rifle half raised to his shoulder; and even in that first frenzied instant in which Lennox looked at him, he saw there was a strange impassiveness, a singular imperturbability on his face.
"Shoot, man!" Lennox shouted. "What are you waiting for?"
But Dan didn't shoot. His hand whipped to his face, and he snatched off his thick-lensed glasses. The eyes that were revealed were narrow and deeply intent. And by now, the frenzied coyote was not fifty feet distant.
All that had occurred since the animal charged had possibly taken five seconds. Sometimes five seconds is just a breath; but as Lennox waited for Dan to shoot, it seemed like a period wholly without limit. He wondered if the younger man had fallen into that strange paralysis that a great terror sometimes imbues. "Shoot!" he screamed again.
