“Upon my word, it looks somewhat as if something or somebody had inhabited it.”
Frank made this statement in all seriousness. It certainly did look as if the cavern had been inhabited by some animal, or even human beings.
There seemed to be a well beaten path over the icy surface.
This extended into the cavern an indefinite way.
Frank was now interested.
He was determined to follow it.
Accordingly he thrust some fresh cartridges into the breech of his rifle and started into the cavern.
Barney followed him.
For some way they kept on. The path was plain and well worn. But as yet nothing had been seen of animal or human being.
The cavern was now enlarging into mighty arched chambers.
