"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 passageway is blocked with rocks." "Did you get in from below?" cried Phil. "We got in from up here." A few words more passed, and the two boys on the upper ledge of rocks passed 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. "Thank heaven, none of us were killed," added Roger. "No more underground exploring for me," avowed Phil. "More than once I thought we would be buried alive!" "That is what I was afraid would happen to me," said Dave, seriously. "Yes, we can all thank heaven we are out of it." "And now to hunt up Blower and Mr. Dillon," came from the senator's son. "If only they are safe!" murmured Dave. For the time being those who had been on the mountainside below them were forgotten. It was hard work to make their way from rock to rock. All the trails were gone, and they had to proceed with extreme care, for fear of dislodging some rock and rolling down into the valley with it. "There they are!"
