“Have you got a camp near by?” questioned Jack.

“Yes; we’re right where we can keep our eyes on you.”

The men went out and once more the four Rovers were left to themselves. Jack and Randy now felt better, and while the latter took up the lantern the young major made a careful inspection of the walls of the cavern.

This inspection was disappointing. There were several nooks and angles in the back of the cave and one large crack and several small ones, all leading upward. But nothing in the way of an opening large enough to admit the passage of the body was revealed.

“It isn’t likely that those fellows would leave any loophole for us,” remarked Randy, as he held up the lantern. “They probably went over this place very carefully before they set those logs up and chained them.”

“I suppose that’s true,” was Jack’s answer. “But I’m going to get out of here somehow if I possibly can.”

“Humph! I guess we all want to get away if it can be done, Jack.”

“If we don’t get away soon those rascals will hold our dads up for thousands and thousands of dollars.”

“I know that, too. But we’re not going to be able to get away if this prison is secure, and if they’re going to set a guard to watch us. For all you know, they may be listening to every word we’re saying.”
