"I don't believe there's going to be any explosion at all!" exclaimed Elmer. "He wouldn't be apt to lay a fuse that would burn fifteen or twenty minutes, and you've certainly been that length of time coming up here, to say nothing of the time we've been talking!"
"All right!" Tommy exclaimed. "Perhaps he was loading up that pillar with dynamite just for the fun of it!"
"It would be a nice thing to have him blow that money out of the pillar and get away with it, wouldn't it?" scoffed Will.
"Come on, then," shouted Tommy, "I can take you to the firing line in about a minute. If you want to see an earthquake in a coal mine, just come along with me! You'll see it, all right!"
The boys left the old tool house without spending any more time in conversation, and hastened down the ladders to the lower level. On the way down the last gangway they heard some one moving about in the darkness, and then came a cry of warning.
"Stand clear! Stand clear!"
"That's Ventner's voice!" exclaimed Will.
"There's a blast going off in a minute!" the voice came again.
"Now we've gone and done it!" exclaimed Will. "After all the trouble we've taken to make that fellow think we've left the country, we've let him bump right into us. I wonder if he really has fired the fuse."
"Stand clear! Stand clear!" shouted the voice.
