Without further discussion, the man sat down. His captor stood behind him, one hand on the shoulder of his prisoner, his eyes watching the point of the gulch at which the enemy would appear. Two mounted men showed presently in silhouette. Almost opposite the grove they drew up. "Mighty queer what has become of Hank," one of them said. "But I don't reckon there's any use looking any farther. You don't figure he's aiming to throw us down--do you, Buck?" "Nope. He'll stick, Hank will. But it sure looks darned strange. Here's him a-ridin' along with us, and suddenly he's missin'. We hear a yell, and go back to look for him. Nothin' doin'. You don't allow the devil could have come for him sudden--do you, Jeff?" It was said with a laugh, defiantly, but none the less Jack read uneasiness in the manner of the man. It seemed to him that both were eager to turn back. Giant boulders, carved to grotesque and ghostly shapes by a million years' wind and water, reared themselves aloft and threw shadows in the moonlight. The wind, caught in the gulch, rose and fell in unearthly, sibilant sounds. If ever fiends from below walk the earth, this time and place was a fitting one for them. Jack curved a hand around his mouth, and emitted a strange, mournful, low cry, which might have been the scream of a lost soul. Jeff clutched at the arm of his companion. "Did you hear that, Buck?" "What--what do you reckon it was, Jeff?" Again Jack let his cry curdle the night. The outlaws took counsel of their terror. They were hardy, desperate men, afraid of nothing mortal under the sun. But the dormant superstition in them rose to their throats. Fearfully they wheeled and gave their horses the spur. Flatray could hear them crashing through the brush. He listened while the rapid hoofbeats died away, until even the echoes fell silent. "We'll be moving," he announced to his prisoner. For a couple of hours they followed substantially the same way that Jack had taken, descending gradually toward the foothills and the plains. The stars went out, and the moon slid behind banked clouds, so that the darkness grew with the passing hours. At length Flatray had to call a halt. "We'll camp here till morning," he announced when they reached a grassy park. The horses were hobbled, and the men sat down opposite each other in the darkness. Presently the prisoner relaxed and fell asleep. But there was no sleep for his captor. The cattleman leaned against the trunk of a cottonwood and smoked his pipe. The night grew chill, but he dared not light a fire. At last the first streaks of gray dawn lightened the sky. A quarter of an hour later he shook his captive from slumber. "Time to hit the trail." The outlaw murmured sleepily, "How's that, Dunc? Twenty-five thousand apiece!" "Wake up! We've got to vamose out of here."
