He was relieved, just the same, when the big cowman rode back, an hour later, and took up the vigil with him. The two talked in subdued tones as they walked back and forth, the lad expressing the opinion that they would find Stacy unharmed when they once discovered the mysterious place into which he had unwittingly stumbled.

"You see, those walls are so thick that we couldn't hear him even if he did call out. He may even have gotten in where they buried those monks we've heard about. I hope not, though."

"He wouldn't know it," said Big-foot.

"No, probably not in the darkness. Did you bring that lantern?"

"Pshaw! I forgot it. Mebby I'd better go back and get it."

"No; never mind, Big-foot. The moon will be up after a time. Then we shall not need it. You are going in for the ten-thirty trick, are you not?"

"That's what the boss said," replied Big-foot.

"Guess we are not going to have any more trouble with them," said Tad, nodding toward the herd.
