While Allen and Watson were talking at the entrance to the cavern, Noel, out of idle curiosity, procured a torch from the camp fire and went on a tour of observation.
The cavern proved to be a narrow and rambling affair, being nothing more or less than a split in the mountain side. The floor was uneven and back from the entrance arose in a series of rough steps.
Up these steps climbed the young man until he had gained a position fully fifty feet above the mouth of the cavern.
At a great distance he heard the falling of water, as the rain swept over some rocks at a rear entrance to the cavern.
Curious to see where the cavern led to he continued his climbing until the light of the camp fire was left far behind.
His torch was burning low but he whirled it into a blaze and went on once more.
Occasionally he slipped, for the rocks were now wet, but this did not daunt him.
At last he reached a spot where the water was flowing in a miniature waterfall. There was an opening over his head but it was out of reach.
"This must be a pretty place in the daylight,"
