“Here he is! Help me!” returned Bob.

“I will.”

Casco’s face fell when he heard that Bob had help close at hand. He made another effort to push the young photographer off, and had almost succeeded when the train-hand appeared.

“By hookey!” cried the man. “Stop that, you villain!”

Just then Casco succeeded in making Bob let go his hold. But now the train-hand caught the youth by the arm, and drew him back in safety to the platform.

“There you are. It was a narrow escape.”

“Thank you!” gasped Bob. “Indeed it was.”

“So he’s safe in that car.”

“Yes.”

“Just wait till I call Jack, and we’ll bag him.”
