“Well, we will have to fight our way out,” said Frank, desperately.

Then a happy thought seemed to strike him.

“But first let us see if there is not some other method of leaving the place,” he cried.

“Bejabers, I don’t think that,” cried Barney, looking doubtfully at the high surrounding cliffs.

“Perhaps not!”

However, Frank turned the Horse about and began to make a circle of the enclosure.

But everywhere the cliffs seemed to present the same impregnable face.

There did not seem a crevice anywhere by which one could have hoped to crawl out of the place.

It was a hopeless outlook.

There seemed no other way but to fight a way out through the pass.
