The thought forced itself upon Dave in spite of his effort to take a more cheerful view of the situation. He was hemmed in--not an avenue of escape seemed open.

"I won't give up! I won't! I won't!" he muttered, half savagely, and got up from the rock on which he had sunk down to rest. Climbing around in that place where the footing was so uncertain had taken both his wind and his strength, and he was panting, and his knees shook beneath him.

Only a short time had elapsed since that dreadful first shock had come, yet to the youth it seemed an age.

He looked at the torch. It had burned well down and would not last much longer. And when it was gone he would be left in total darkness!

This was a new cause for fear, and it made Dave move around faster than ever.

Suddenly he stopped short. A new sound had reached his ears--a strange, weird sound that made his flesh creep and his hair stand on end.

It was the cry of a wildcat--shrill and uncanny in that pent-up s.p.a.ce.

Slowly it came nearer, although from what direction our hero could not at first make out.

He waited behind a spur of rocks and the cry--it was more a whine of fright than anything else--came closer. Then, on a shelf of rocks but a short distance away, Dave caught sight of the beast.

It was limping along on three feet, dragging a bleeding hind leg and a bleeding tail behind it. Evidently it had been caught between the falling stones as in a trap and had pulled itself loose in a mad effort to save its life.

For the moment Dave forgot his other perils as he faced the beast.

Evidently the wildcat had scented the youth, for it gave a savage cry as of defiance. Perhaps it thought that Dave was responsible in some way for the pain it was suffering.

The youth's hand was on the rocks and almost unconsciously it closed on a sharp stone about as big as his fist. Raising the stone, he took quick aim and threw it at the wildcat.

As my old readers know, Dave was a good baseball player and, at Oak Hall, had often filled the pitcher's box with credit. He threw the stone with accuracy and vigor, and it landed fairly and squarely on the head of the wildcat.

There was a weird screech, and the beast whirled around and around on the rocks, coming closer and closer to our hero. Once it clawed savagely at Dave, but he shoved the creature off before any damage was done. Then it fell down in a cleft of some rocks, where it snapped and snarled until Dave sent down a heavy boulder on top of it, thus ending its misery.

"Phew!" gasped the youth, after the excitement was over. "That was almost as bad as when we shot the mountain lioness!"

He had dropped the end of his torch, but now picked it up once more and commenced to move around as before. He proceeded blindly, not knowing in what direction to turn to reach the outer air.

"Where can the others be?" was a question he asked himself more than once. Were they, too, caught underground, or had the awful landslide carried them down into the valley and buried them?

In the course of his climbings Dave presently came to a new turn, one which had before escaped his attention. This turn led upward and gave him fresh hope. But, just as he fancied that he was getting close to the outer air, he reached a flat wall, and further progress in that direction was out of the question.

His heart sank like lead in his bosom, and he walked slowly back to the point from which he had started. How to turn next he did not know.

Half an hour pa.s.sed, and Dave was almost in despair. His torch had reached its end and was on the point of going out. Then, not knowing what else to do, he set up a cry for help.

There came no reply, and he cried again. Then he pulled out his pistol and fired a shot.

The discharge of the weapon echoed and reechoed throughout the cave and brought down several small stones. Then, to Dave's intense surprise and joy, an answering shot came back.

"Who is it?" he yelled. "I am here! This way! _This way!_"

"h.e.l.lo!" was the long-drawn-out answer, coming from some point that appeared to be over his head. "Where--are--you?"

And then, as Dave's torch gave a final flicker and went out, our hero saw a shaft of light move over the rocks above his head.

"It's Roger's flashlight!" he told himself, and then he set up another cry.

The rays of the flashlight became stronger and of a sudden they shot downward, directly in Dave's face.

"It's Dave!" came in Roger's voice. "Are you all right?"

"Yes," was the ready reply. "That you, Roger?"

"Yes. Phil is with me."

"Were you hurt?"

"Shaken up a bit, that's all," replied Phil, and now Dave saw his chums standing in an opening that was about eight feet above his head.

"We had better get out of here," went on Roger, quickly. "Another landslide may bury us alive!"

"I've found the mine!" cried Dave. "I've got some nuggets from it--and a pick, a crowbar, and a broken lantern, all with your uncle's initials on them!"

"Good for you!" cried the senator's son. "Phil and I found some evidences of the mine up here--an old coat of my uncle's and some of his stakes. But we had better get out now--we can talk this thing over later."

"I can't get out down here--the pa.s.sageway is blocked with rocks."

"Did you get in from below?" cried Phil. "We got in from up here."

A few words more pa.s.sed, and the two boys on the upper ledge of rocks pa.s.sed down a length of rope they carried, and by that means Dave was soon enabled to climb up and join them. There were no more quakes, so all began to breathe more freely. Yet they felt that it would be advisable to leave the cave-mine without delay.

"It certainly is the lost Landslide Mine!" exclaimed Roger. "Oh, how glad I am that it has been found! And how glad my folks will be to get the welcome news!" Even the peril of the present situation could not rob him of his joy over the discovery that had been made.

He and Phil had picked up several small nuggets, so that all were sure they had really discovered the lost mine.

"But they will have to be careful how they work this mine," said Dave, as he walked along with his chums. "They can't work it from below--it will be too dangerous."

"Oh, they'll find some way, don't fear," answered Roger. "As long as they know the gold is there, they'll find a way to get it."

"Where are the others?" went on Dave, as he saw daylight ahead, much to his satisfaction.

"That we don't know," answered Phil. "But we are hoping they are safe."

"By the way, did you see Merwell and Haskers?" cried Dave, suddenly.

"Why, no--not since they ran away from our camp," returned Roger.

"I saw them--just before I found this opening. They were below me, the two of them and Sol Blugg."

"Maybe they got caught," muttered Phil.

No more was said just then, for the boys had to do some climbing over several big rocks, and needed their breath. Then they made a turn, and a moment later came out into the sunlight.

"Oh, how good it seems to be out in the air once more!" murmured Dave.
