“By the——!”

Then on the instant an almost unconscious movement, simultaneously executed, set their horses racing across the open in the direction of the suspended lake.

The powerful Cæsar, with his lighter burden, was the first to reach the spot. He drew up more than two hundred yards from where the domed roof forming the lake bed hung above the waters of the creek. He could approach no nearer, and his rider sat gazing in wonder at the spectacle of fallen rock and soil, and the shattered magnificence of the acres of crushed and broken pine woods which lay before him.

The whole face of the hill for hundreds and hundreds of feet along this side had been ruthlessly rent from its place and flung broadcast everywhere, and, in the chaos he beheld, Buck calculated that hundreds of thousands of tons of the blackened rock and subsoil had been dislodged by the tremendous fall.

Just for an instant the word “washout” flashed through his mind. But he dismissed it without further consideration. How could a washout sever such rock? Even he doubted the possibility of lightning causing such destruction. No, his thoughts flew to an earth disturbance of some sort. But then, what of the lake? He gazed up at where the rocky arch jutted out from the parent hill, and apprehension made him involuntarily move his horse aside. But his observation had killed the theory of an earth disturbance. Anything of that nature must have brought the lake down. For the dislodgment began under its very shadow, and had even further deepened the yawning cavern beneath its bed.

The Padre’s voice finally broke his reflections, and its tone suggested that he was far less awed, and, in consequence, his thoughts were far more practical.

“Their works are gone,” he said regretfully. “I’d say there’s not a sluice-box nor a conduit left. Maybe even their tools are lost. Poor devils!”

The man’s calm words had their effect. Buck at once responded to the practical suggestion.

“They don’t leave their tools,” he said. Then he pointed up at the lake. “Say, what if that had come down? What if the bowels o’ that hill had opened up an’ the water been turned loose? What o’ the camp? What o’ the women an’—the kiddies?”

His imagination had been stirred again. Again the Padre’s practice brought him back.
