"It would be something of a joke if we should butt into that detective now, wouldn't it?" Sandy laughed, as they passed down from the second level.
"I shouldn't consider it much of a joke," replied Tommy. "We took a lot of pains to make him think we'd gone out of town!"
As the boys walked softly down the center gangway they heard a fall of rock which seemed to come from the passage next north. This passageway was connected by the main one with a cross-heading situated perhaps three hundred feet from the shaft.
"I don't know much about mines," whispered Elmer as the boys stopped and listened to the clatter of the rocks as they settled down on the floor of the cavern, "but that sounds to me a whole lot like a fall from the roof. I hope the boys are not injured."
The boys walked faster until they came to the cross-passage and then turned to the right. Just as they left the main gangway, they heard the sound of running feet and directly the distant creaking of the ladder rungs.
"Some one's making a hot-foot for the surface!" exclaimed Tommy.
"That's Ventner!" declared Sandy.
"How do you know that?"
"Because he wears heavy boots. We have rubbers on, and Jimmie and Dick, who are down in the mine, are also wearing rubber boots!"
"The farther he gets away from the mine, the better it will suit me," Elmer broke in. "I wish he'd go away and stay for a hundred years!"
