This suggestion seemed not a bad one. So, as they wandered on through the mist, Randall fired his rifle at intervals.
It was not long ere an answer came. It was a faint shot, and far in the distance.
But it was enough.
It indicated the fact that the Scorcher was not beyond hearing. Frank tried to locate the searchlight’s glare.
The sound of firing seemed to come from a point higher up the mountain side, and the adventurers accordingly kept on in that direction.
At intervals Randall fired his gun, and the answer came. But one fact impressed the trio curiously.
This was that the firing sounded more and more distant, though they were going as the sound guided them directly toward it.
The meaning of this was not easy to understand.
Fainter and fainter grew the answering shots. Then Randall halted.
“We are certainly going in the wrong direction!” he declared. “Pretty quick we won’t be able to hear those shots at all.”
