RIDERS OF THE PURPLE SAGE
and, though age-worn, he recognized them as steps cut in the rock by the cliff-dwellers. With a pulse beginning to beat and hammer away his calmness, he eyed that indistinct line of steps, up to where the buttress of wall hid further sight of them. He knew that behind the corner of stone would be a cave or a crack which could never be suspected from below. Chance, that had sported with him of late, now directed him to a probable hiding-place. Again he laid aside his rifle, and, removing boots and belt, he began to walk up the steps. Like a mountain goat, he was agile, sure-footed, and he mounted the first bench without bending to use his hands. The next ascent took grip of fingers as well as toes, but he climbed steadily, swiftly, to reach the projecting corner, and slipped around it. Here he faced a notch in the cliff. At the apex he turned abruptly into a ragged vent that split the ponderous wall clear to the top, showing a narrow streak of blue sky.
At the base this vent was dark, cool, and smelled of dry, musty dust. It zigzagged so that he could not see ahead more than a few yards at a time. He noticed tracks of wildcats and rabbits in the dusty floor. At every turn he expected to come upon a huge cavern full of little square stone houses, each with a small aperture like a staring dark eye.
