Billy Duffy was an Irishman, a blacksmith, and a drunkard. He had the Keltic aversion from steady work, and stuck to his forge only long enough to get money for drink; when that was spent, he returned to work. Billy was coming home one day after one of these drinking-bouts, soberer than usual, when he exclaimed to himself, for the thirst was upon him, “By God! I would sell myself to the devil if I could get some more drink.”
