As he did so he looked at Dick and said in triumph: "Three good cigars that the rebels have left behind.

Have one, Mason ?" "Thanks, but I don't smoke." "All right, I'll find someone else who does." He pulled off a piece of paper wrapped around them, threw it on the floor and put the cigars in his pocket.

Dick was about to turn away when he happened to glance at the wrapping lying on the floor.
His eyes were caught by the words written in large letters: HEADQUARTERS OF THE ARMY OF NORTH-- Something seemed to shoot through his brain.

It was like a flash of warning or command and he obeyed at once.

He picked up the paper and smoothed it out in his hand.
