"Will the dynamite explode?" asked Walter half fearfully.
"Probably not. I hope not. But you can't tell anything about these high explosives. They're very freaky. All we can do will be to remain here and wait for the car either to stop somewhere after the power has been turned off or to rip its way through the wreck we just left. At any rate we are safe in here."
The boys breathed a sigh of relief.
"Then, there is no danger to us?" asked Ned Rector.
"The danger is minimized."
"How far are we from where we started?"
"Probably a couple of miles."
"My! the Professor will be half scared to death when he hears what a fix we are in," half laughed Ned.
"The foreman, Mr. Acomb, said he would telephone to the other end of the drift telling them we were all right and not to worry about us," said Phipps. This relieved the boys' minds of one source of worry.
"Hark!" cautioned the young engineer.
