"But I've got to get out! I've got to!" he told himself, over and over again. "I can't stay here!" And then he tried to climb the rocks in front of him once more.
It was hard work, especially with the torch in hand. Once Dave tried to carry the torch between his teeth, but it was too short, and his face was scorched, while the smoke almost strangled him.
Suddenly he slipped on some wet rocks and went down and down, he knew not whither. He was stunned by the fall, and the precious light slid from his grasp and rolled several yards away.
"Oh!" he murmured as he gathered his scattered senses and arose slowly to his feet. Then he saw that the torch was on the point of going out and he made a dash for it, and swung it once again into a faint blaze.
As he stepped around he noticed something else that added to his dismay. In his fall he had twisted his left ankle, which gave a twitch that made him shut his teeth hard, to keep from crying out with pain.
"Oh, I hope I haven't broken it!" he muttered. "However am I going to walk on it, even if it is broken?"
In sheer desperation he commenced to climb up the wet rocks down which he had tumbled. The ankle hurt not a little, yet in his excitement the youth scarcely noticed the pain. His one thought was to get out of the cave before another landslide or earthquake occurred.
A few minutes later found Dave on the level from which he had fallen. As he scrambled over the rocks something caught the glare of the torchlight. The youth picked up the object.
"Another nugget!" he told himself. "The place must be full of them!"
But what good would these nuggets be to him or his friends if he could not get out of the mine-cave? He was deep underground and this new landslide or earthquake might bury him and the contents of the mine forever!
