"Wonder where we will camp for to-night," he mused, as he gazed around him. "I hope we find some nicer spot than this. This looks so lonely and spookish. Well, I suppose I've got to go on, or they'll get ahead of me, and it would be no fun to get lost. A fellow——"
Dave came to a stop in his musings and also drew up his horse. He had taken but a few steps farther, and now saw, to one side of the rocky defile, a small opening, leading into a sort of hill.
"Looks as if it might be a kind of cave," he told himself. "I guess I'd better dismount and take a look inside. It might be the entrance to the lost mine!"
Suiting the action to the word, Dave leaped from his horse, and letting the steed stand, approached the cave. The entrance was comparatively small and he had to stoop down to peer inside.
As he did this there came a sudden ominous growl from the interior of the cave. It was the growl of a wild beast and caused the youth to leap back in alarm. Then a slinking body came into view and a full-sized mountain lion showed himself!
Dave ran toward his horse. But as the mountain lion gave another growl, the horse snorted and plunged, in sudden fright. Then the steed took to his heels and went clattering along the rocky defile.
"Stop!" yelled the youth. "Stop!" And then he set up a call for assistance.
At the sound of his voice, the mountain lion paused, just outside the entrance of the cave. Evidently he did not wish to become trapped in such narrow quarters. He eyed Dave with glaring eyeballs, and showed his gleaming teeth. His tail began to switch from side to side, and he crouched low, as if contemplating a spring at the boy.
