Dust! They were dust on the floor or at the foot of the shelf, and their habitations and utensils endured. Venters felt the sublimity of that marvelous vaulted arch, and it seemed to gleam with a glory of something that was gone. How many years had passed since the cliff-dwellers gazed out across the beautiful valley as he was gazing now? How long had it been since women ground grain in those polished holes? What time had rolled by since men of an unknown race lived, loved, fought, and died there? Had an enemy destroyed them? Had disease destroyed them, or only that greatest destroyer--time? Venters saw a long line of blood-red hands painted low down upon the yellow roof of stone.

Here was strange portent, if not an answer to his queries. The place oppressed him. It was light, but full of a transparent gloom. It smelled of dust and musty stone, of age and disuse. It was sad. It was solemn. It had the look of a place where silence had become master and was now irrevocable and terrible and could not be broken. Yet, at the moment, from high up in the carved crevices of the arch, floated down the low, strange wail of wind--a knell indeed for all that had gone.

Venters, sighing, gathered up an armful of pottery, such pieces as he thought strong enough and suitable for his own use, and bent his steps toward camp. He mounted the terrace at an opposite point to which he had left. He saw the girl looking in the direction he had gone. His footsteps made no sound in the deep grass, and he approached close without her being aware of his presence. Whitie lay on the ground near where she sat, and he manifested the usual actions of welcome, but the girl did not notice them. She seemed to be oblivious to everything near at hand. She made a pathetic figure drooping there, with her sunny hair contrasting so markedly with her white, wasted cheeks and her hands listlessly clasped and her little bare feet propped in the framework of the rude seat. Venters could have sworn and laughed in one breath at the idea of the connection between this girl and Oldring's Masked Rider. She was the victim of more than accident of fate--a victim to some deep plot the mystery of which burned him. As he stepped forward with a half-formed thought that she was absorbed in watching for his return, she turned her head and saw him. A swift start, a change rather than rush of blood under her white cheeks, a flashing of big eyes that fixed their glance upon him, transformed her face in that single instant of turning, and he knew she had been watching for him, that his return was the one thing in her mind. She did not smile; she did not flush; she did not look glad. All these would have meant little compared to her indefinite expression. Venters grasped the peculiar, vivid, vital something that leaped from her face. It was as if she had been in a dead, hopeless clamp of inaction and feeling, and had been suddenly shot through and through with quivering animation. Almost it was as if she had returned to life.
