Virey could be plainly seen, embedded to his hips in the loose stones. Writhing, squirming, wrestling, he sought to free himself from that grip of granite. In vain! He was caught in a vise of his own making. Prisoner of the mountain-side that he had used to betray his wife! He had turned toward Adam, face upward. There seemed a change in him, but in the racking excitement of that moment Adam could not tell what.

Then that desert instinct, like the bursting of a flood, moved Adam to the violence of strife, the ruthlessness of nature, the blood-spilling of men. Madness of hate seized him. The torrid heat of that desert sun boiled in his blood, the granite of the slope hardened in his heart, the red veils of smoky shadows colored his sight. Loneliness and solitude were terrible forces of nature—primitive as the beginnings of life. For years the contending strife of the desert had been his. For months desolation, death, decay of Death Valley!

“My turn!” he yelled, in voice of thunder, and, bristling haired, supple, and long armed, with strength and laugh and face of a savage, he heaved a huge rock.

It rolled, it cracked, it banged, it hurtled high, to crash and smash, and then, leaping aloft, instinct as if with mockery, it went over Virey’s head to go on down over the precipice, whence it sent up a sliding roar. Adam heaved another stone and watched it. Virey grew motionless as a statue. He could not dance and dodge away from rolling rocks as Adam had done. How strangely that second rock rolled! Starting in line with Virey, it swerved to the right, then hit the slope and swerved back in line, then, hitting again, swerved once more, missing the miserable victim by a small margin.

“Aha there, Virey!” yelled Adam, waving his hands. “All day and all night I’ll roll stones!”

Virey was mute. He was chained. He was helpless. He could not move or faint or die. Retribution had overtaken him. The nature of it was to be the nature of the slow torture and merciless death he had inflicted upon his wife. As he had chosen the most deadly and lonely and awful spot on earth to hide her and kill her, so the nature that he had embraced now chose to turn upon him. There was law here—law of the unknown forces in life and in the elements. At that very moment a vulture streaked down from the hazed heights and sailed, a black shadow of wide-spread wings, across the slope. What had given this grisly-omened bird sight and scent illimitable?

Adam braced his brawny shoulder under the bulge of a rock weighing tons. Purple grew his face. His muscles split his shirt. His bones cracked. But there was a nameless joy in this exercise of his enormous strength. They were two men—one was weak, the other was strong. And nature could not abide both. The huge rock grated, groaned, stirred, moved—and turned over, slowly to roll, to crunch, to pound, and then to gather speed, growing a thing of power, ponderous, active, changing, at last to hurtle into the air, to plunge down with thunderous crash, then to roll straight as a bee line at Virey. But a few yards in front of him it rose aloft, with something of grace, airily, and, sailing over Virey’s head, it banged and boomed out of sight below. Long the echoes clapped, and at last the silence, the speaking silence of that place, closed on the slope. It awoke again to Adam’s rolling of a stone and another and another and then two together. All these rocks rolled differently. They were playthings of the god of the mountain. The mover of thunderbolts might have been aiming his colossal missiles at an invisible target. All these rolling stones seemed to head straight for Virey, but they were at the last instant deflected by chance. They hit the slope and passed wide or high. They were in league with the evil spirit that had dominated Virey. They were instruments of torture. They were of the nature of the desert. They belonged to Death Valley.

Adam did not soon tire at his gigantic task. The rolling stones fascinated him. From dead things they leaped to life. How they hurtled through space! Some shot aloft a hundred feet. Others split, and rolled, like wheels, down and down, the halves passing on either side of the doomed Virey. A multitude of rocks Adam turned loose, and then another multitude. Into the heaving of every one went his intent to kill. But Virey bore a charmed life.

A time came when Adam rolled his last stone. Like the very first one, it sped straight for Virey, and just as it appeared about to crush him it veered to one side. Adam stared grim and aghast. Could he never kill Virey as Virey had murdered his wife and tried to kill him?

“She—said I’d—never kill—you!” panted Adam, and the doubt in him was a strange, struggling thing, soon beaten down by his insatiable rage. Then he took a stride downward, meaning to descend and finish Virey with his hands.
