"Oh, of course! It's wonderful to think of how they got here, Boris, riding right through the enemy's country! It's like the work cavalry did on both sides in our Civil War. They used to get behind the enemy's lines and cut telegraph wires and railways all the time."

"Looking for the raiders," said Fred. "Let's hurry. I think we ought to report what has happened by wireless. Your father's party may need help."
