“I shall follow the canyon up and try to dislodge the outlaws,” replied Frank.

“Very good, sir?” cried Barney, with readiness. “We’ll go ahead thin?”

“Yes.”

Barney took the reins and the Steam Man went on up the gorge.

In a short while they had reached the dam which had held back the lake.

Here a course was found directly out upon a vast plain.

Frank was about to direct the man’s course thither when an incident occurred to for a moment delay them.

A loud and harsh voice came from the cliff above.

“Hello, down there!”

The speaker could not be seen. The Steam Man came to a halt.
