A dozen feet farther, some four-footed animal suddenly leaped to the edge of the bank, sniffed, and disappeared noiselessly. So taut were his nerves strung that the Sergeant sank upon his knees, releasing one hand to grip his revolver, before he realized the cause of alarm--some prowling prairie wolf. Then, with teeth grimly locked, bending lower and lower, he crept across the rutted trail, and past the dead body of the Indian. Not until then did he dare to breathe naturally or to stand upright; but now, the gully, bending to the right, led away from danger, every step gained adding to their safety. He was confident now, full of his old audacity, yet awake to every trick of plainscraft. The girl's head rested against his shoulder, and he bent his cheek to hers, feeling its warmth. The touch of his unshaven beard pricked her into semi-consciousness, and she spoke so loud that it gave him a thrill of apprehension. He dared not run in the darkness for fear of stumbling, yet moved with greater swiftness, until the depression ended at the river. Here, under the protection of the bank, Hamlin put down his burden and stood erect, stretching his strained muscles and staring back into the dark. What now? Which way should they turn? He had accomplished all he had planned for himself back there in the coach, but now he became aware of other problems awaiting solution. In less than an hour it would be daylight; he almost imagined it was lighter already over yonder in the east. With the first dawn those watchful Indians, creeping cautiously closer, would discover the stage deserted, and would be on their trail. And they had left a trail easily followed. Perhaps the hard, dry ground might confuse those savage trackers, but they would scour the open country between bluff and river, and find the dead warrior in the gully. That would tell the story. To go west, along the edge of the river, wading in the water, would be useless precaution; such a trick would be suspected at once, and there was no possibility of rescue from that direction. They might as well walk open-eyed into a trap. There was but one hope, one opportunity--to cross the stream before dawn came and hide among those shifting sand-dunes of the opposite shore. Hamlin thoroughly understood the risk involved, the treacherous nature of the Arkansas, the possibility that both might be sucked down by engulfing quicksand, yet even such a lonely death was preferable to Indian torture.
