SCENE.- A transparent curtain of net extends across the stage from right to left, about six feet back of the foot-lights. Throughout the text, what goes on in front of this curtain is referred to as the Real-play; what goes on behind the curtain is the Play-play. Upon the sides of the curtain, Right and Left, is painted a representation of an attic room in a tenement house. The curtain becomes thin, practically nothing at center, so the audience sees the main action of the Play-play clearly. At Right in the Real-play is a window opening on a fire-escape, and in front of the window a cot where the child sleeps. At Left in the Real-play is a window, an entrance door, a flat-topped desk and two chairs. This setting of the Real-play remains unchanged throughout the four acts. The scenes of the Play-play change with each act. For Act I the set is a drawing-room in a wealthy old New York home, entrances Right-center and Left.
