“God, it’s a woman!”

He leaped, at the words, out of the shadow of the butte into the moonlight of the level, straight into the path of the running horse, which at sight of him slid, reared and came to a halt, snorting and trembling. Trevison had recognized the girl; he flung himself at the horse, muttering: “Dynamite!” seized the beast by the bridle, forced its head around despite the girl’s objections and incoherent pleadings—some phrases of which sank home, but were disregarded.

“Don’t!” she cried, fiercely, as he struck the animal with his fist to accelerate its movements. She was still crying to him, wildly, hysterically, as he got the animal’s head around and slapped it sharply on the hip, his pistol crashing at its heels.

The frightened animal clattered over the back trail, Trevison running after it. He reached Nigger, flung himself into the saddle, and raced after Levins, who was already far down the level, following Rosalind’s horse. At a turn in the butte he came upon them both, their horses halted, the girl berating Levins, the man laughing lowly at her.

“Don’t!” she cried to Trevison as he rode up. “Please, Trevison—don’t let that happen! It’s criminal; it’s outlawry!”

“Too late,” he said grimly, and rode close to her to grasp the bridle of her horse. Standing thus, they waited—an age, to the girl, in reality only a few seconds. Then the deep, solemn silence of the night was split by a hollow roar, which echoed and re-echoed as though a thousand thunder storms had centered over their heads. A vivid flash, extended, effulgent, lit the sky, the earth rocked, the canyon walls towering above them seemed to sway and reel drunkenly. The girl covered her face with her hands. Another blast smote the night, reverberating on the heels of the other; there followed another and another, so quickly that they blended; then another, with a distinct interval between. Then a breathless, unreal calm, through which distant echoes rumbled; then a dead silence, shattered at last by a heavy, distant clatter, as though myriad big hailstones were falling on a pavement. And then another silence—the period of reeling calm after an earthquake.

“O God!” wailed the girl; “it is horrible!”

“You’ve got to get out of here—the whole of Manti will be here in a few minutes! Come on!”

He urged Nigger farther down the canyon, and up a rocky slope that brought them to the mesa. The girl was trembling, her breath coming gaspingly. He faced her as they came to a halt, pityingly, with a certain dogged resignation in his eyes.

“What brought you here? Who told you we were here?” he asked, gruffly.
