“ How do you know that I have not been an assassin?"The Bishop replied:--"That is the concern of the good God."Then gravely, and moving his lips like one who is praying or talking to himself, he raised two fingers of his right hand and bestowed his benediction on the man, who did not bow, and without turning his head or looking behind him, he returned to his bedroom.When the alcove was in use, a large serge curtain drawn from wall to wall concealed the altar. The Bishop knelt before this curtain as he passed and said a brief prayer. ”
