“We’ve got to work lively!” said a man’s voice. “Those campers are beginning to suspect there’s something wrong. We’ll have to clear out, bag and baggage, presses, engine and everything.”

“That’s right,” added another. “Lucky we have the car. We can take most of the stuff in that if we have time, and set it up somewhere else. This graft is too good to give up.”

“Where’ll we take it?” a third voice asked, and the boys, who could not see the speakers, wondered how many of them there were.

“Oh, we can stow it away at——” began the man who had spoken first when there came an interruption from his companion.

“No names!” he cautioned.

“Who’s to hear?”

“You can’t tell. Since those boys opened up the floor of the bungalow, there’s no telling what might have happened. Besides, I don’t want old Jason to know where we are going. I’m going to get rid of him; he’s more trouble than help.”

“Especially with that horrible boy of his,” some one said. “Ugh! I can’t bear the creature!”

“Still he’s been useful. He did the tricks all right. But it was a mistake to go to the bungalow. That’s caused all the trouble. We should have stuck to this end of the cave.”

“We had to have an emergency exit,” declared one of the men, “and the bungalow was the best.”
