Bob, Frank, and the officers jumped at once to the ground. Then they separated, the officers on one side of the track and Bob and Frank on the other.
“We ought to get some distance away from the track,” said Bob. “It isn’t likely the gang will remain close at hand when they expect the train to run off.”
“That’s so, Bob,” returned the young man. “Come, here is a path. Let us take that.”
The path led to a spot fully a hundred feet back of the track. They pursued it in silence until Bob caught Frank by the sleeve as a signal to stop.
“What is it?” whispered the young man.
“They are just ahead.”
“You are sure?”
“Yes. I heard Grogan talking.”
“Hark!”
They listened. This time it was Barker who was speaking.
