He had hardly covered half the distance to the outer air when there came another quaking, and more rocks fell, one hitting him on the arm. The torch was knocked from his hand and he tripped and fell. Then came a crash and a roar, and to Dave it seemed as if the end of the world had come. He was more than half-stunned, and he fell against a wall of rocks, wondering what would happen next.


CHAPTER XXIX

ANOTHER LANDSLIDE

It was another landslide, crashing and roaring down the side of the mountain, carrying rocks, dirt, and brushwood before it. The earth roared and shook, and it was said afterwards that the slide could be heard many miles away.

Down in the mine that he had but just discovered, Dave remained crouching against a wall of rock, murmuring a prayer for his safe deliverance from the peril that encompassed him. Every moment he expected would be his last—that those rocky walls would crash in on him and become his tomb. Roar followed roar, as the landslide continued and more rocks fell. Then the air around him seemed to be compressed, until he could scarcely breathe.

"Oh, if I were only out of this!" he thought, and at that moment he would have gladly given all he was worth to have been in the outer air once more.

Gradually the roaring and the quaking ceased, and Dave breathed a little more freely. He groped around in the darkness and managed to locate the fallen torch, which still glowed faintly. He swung it into a blaze with nervous energy.

Was the landslide at an end? Fervidly he prayed that it was. Torch in hand, he tried to make his way to the spot where he had entered the mine.

He soon found this impossible, for the reason that the passageway had shifted, and huge rocks blocked his way. Several times he tried to climb over the rocks, only to fall back helplessly. He cut his hands and broke his finger-nails, but this availed him nothing.
