CHAPTER XXI
IMPRISONED IN A MINE
"That—that's the track that the empty cars go back on, is it not?" asked Tad, after an interval of tense silence.
"Yes."
"The wreck was on the other track."
Tom Phipps nodded.
"Then what harm can the red car, as you call it, do?" interrupted Ned
Rector.
"That remains to be seen. The chances are that the number two track was blocked when the car of ore was spilled out."
"Which means?" questioned Tad.
"That there may be another collision," smiled the assistant superintendent. His was a wan smile, however, and failed to enliven the Pony Rider Boys.
