"I guess there's plenty of room under the peaks for mischief to be plotted," Ed suggested, "I can see pigeon holes all along the cliff."
"Caves, do you mean?" asked Will.
"Sure," was the reply. "Those cliffs are of volcanic formation, and some of the strata are softer than others, and the water has cut into the heart of the range in many places."
"One would naturally suppose that such openings would be filled with ice in Alaska," Will suggested.
"They may be filled with ice in the winter," answered Ed, "but in the summer time they are hiding places for bears and crooked miners."
The boys advanced to the edge of the stream and Will swept his field glass along the distant slope.
Presently he handed the glass to Ed.
"Tell me what you see," he said.
"I see something that looks like the eye of a wild animal looking out over the valley!" answered the boy. "What can it be?"
"My first idea was that some one had built a fire in a cave," Will answered, "but the more I look at it, the more I suspect that the light comes from an electric."
