"Besides, it's the print of a bare foot," Prescott went on. "You see the way in which it is pointing?"
"Yes; toward that patch of low bushes yonder. But our chap couldn't have run through those low bushes, or we'd have seen him."
"Yes; if he had been holding himself erect."
"Or even had he crouched and run," Dave affirmed.
