A tide of passion, first hot as fire, then cold as ice, rushed over Gale when he saw Rojas take the trail toward Mercedes's hiding-place. The little bandit appeared to have the sure-footedness of a mountain sheep. The Mexican following was not so sure or fast. He turned back. Gale heard the trenchant bark of the .405. Ladd was kneeling. He shot again--again. The retreating bandit seemed to run full into an invisible obstacle, then fell lax, inert, lifeless. Rojas sped on unmindful of the spurts of dust about him. Yaqui, high above Ladd, was also firing at the bandit. Then both rifles were emptied. Rojas turned at a high break in the trail. He shook a defiant hand, and his exulting yell pealed faintly to Gale's ears. About him there was something desperate, magnificent. Then he clambered down the trail.
Ladd dropped the .405, and rising, gun in hand, he staggered toward the bridge of lava. Before he had crossed it Yaqui came bounding down the slope, and in one splendid leap he cleared the fissure.
He ran beyond the trail and disappeared on the lava above. Rojas had not seen this sudden, darting move of the Indian.
Gale felt himself bitterly powerless to aid in that pursuit. He could only watch. He wondered, fearfully, what had become of Lash. Presently, when Rojas came out of the cracks and ruts of lava there might be a chance of disabling him by a long shot.
His progress was now slow. But he was ****** straight for Mercedes's hiding-place. What was it leading him there--an eagle eye, or hate, or instinct? Why did he go on when there could be no turning back for him on that trail? Ladd was slow, heavy, staggering on the trail; but he was relentless. Only death could stop the ranger now. Surely Rojas must have known that when he chose the trail. From time to time Gale caught glimpses of Yaqui's dark figure stealing along the higher rim of the crater.
He was ****** for a point above the bandit.
Moments--endless moments dragged by. The lowering sun colored only the upper half of the crater walls. Far down the depths were murky blue. Again Gale felt the insupportable silence. The red haze became a transparent veil before his eyes. Sinister, evil, brooding, waiting, seemed that yawning abyss. Ladd staggered along the trail, at times he crawled. The Yaqui gained; he might have had wings; he leaped from jagged crust to jagged crust; his sure-footedness was a wonderful thing.
But for Gale the marvel of that endless period of watching was the purpose of the bandit Rojas. He had now no weapon. Gale's glass made this fact plain. There was death behind him, death below him, death before him, and though he could not have known it, death above him. He never faltered--never made a misstep upon the narrow, flinty trail. When he reached the lower end of the level ledge Gale's poignant doubt became a certainty. Rojas had seen Mercedes. It was incredible, yet Gale believed it. Then, his heart clamped as in an icy vise, Gale threw forward the Remington, and sinking on one knee, began to shoot. He emptied the magazine. Puffs of dust near Rojas did not even make him turn.
As Gale began to reload he was horror-stricken by a low cry from Thorne. The cavalryman had recovered consciousness. He was half raised, pointing with shaking hand at the opposite ledge. His distended eyes were riveted upon Rojas. He was trying to utter speech that would not come.
Gale wheeled, rigid now, steeling himself to one last forlorn hope --that Mercedes could defend herself. She had a gun. He doubted not at all that she would use it. But, remembering her terror of this savage, he feared for her.
Rojas reached the level of the ledge. He halted. He crouched.
It was the act of a panther. Manifestly he saw Mercedes within the cave. Then faint shots patted the air, broke in quick echo.
Rojas went down as if struck a heavy blow. He was hit.
But even as Gale yelled in sheer madness the bandit leaped erect.
