Circumstances occurred to prevent this contingency. Loud shouts went up from below, and great excitement seemed to ensue.

Then the distant exchange of rifle shots was heard.

Frank exchanged startled glances with Montaine, and a sudden inspiration seized him.

“My soul!” he cried. “Do you believe it possible that Silver Sam and his men have whipped the greasers and have penetrated to this place?”

“Begorra, there’s a fight goin’ on out there phwativer it manes!“cried Barney.

“Yes, and a hot one,” added Montaine.

This was true.

The report of rifle shots were now rapid and near at hand. The yells and cries of the contestants could be plainly heard.

The amphitheater had been cleared of greasers in a twinkling.

It seemed to the prisoners a good opportunity to make an attempt to escape.
