"Oh, I don't know," replied Canfield. "The matter was reported to me early this morning. I couldn't find you before, or you should have had the news sooner. It isn't safe for you to go into the mine!"

"Your information," grinned Will, "comes a little bit late, but it's all right, just the same. Ventner is in there, and there are two men with. It's a mystery how they made their way in without being discovered, but it seems that they did so."

"What are you going to do?" asked Canfield.

"We're going on into the mine."

"In the face of my warning?"

"It's just this way," answered Will. "We left two of the boys on guard in this passage, not so very long ago, and they have disappeared. We suspect that Ventner and the two men to whom you refer have good reason to know something of their whereabouts."

"They won't injure the boys!" pleaded Canfield.

"We don't mean to give them a chance!" insisted Elmer. "We're going to jerk those boys out so quick it'll make their heads swim!"

"But it's positively dangerous!" urged the caretaker.

"If there wasn't an element of danger in the situation, we wouldn't be here!" replied Will, "I don't see as we need to run away from two hold-up men, anyway," the boy went on. "Here are five boys and one full grown man in the gangway. We ought to give a pretty good account of ourselves, in case some one starts anything!"
