Paint on canvas a scene representing a room or library, and showing a bookcase. The part of the bookcase that would contain the shelves and books must be cut out of the canvas, the framework only being left, and this framework must be so painted as to have a solid, substantial appearance. The canvas that has been cut out must be replaced by a black net or gauze, and the shelves and books must be painted on the gauze, so that when lighted up from the front the bookcase will appear complete. Behind the gauze and close to it the movable cat cloth is hung. This is a piece of canvas dead black in colour, 12 in. larger all round than the cutout portion of the bookcase. The ghost or vision stands behind the cat cloth. The light is now turned down in the scene so that the room is darkened, and at the same time a good light is turned on at the back, and is so arranged that it falls on the front of the figure either from the left- or from the right-hand side. While darkening the scene and turning up the lights behind the eat cloth must be pulled up or drawn on one side, and the ghost scene is complete.

With judicious management this will answer for tableaux by adding accessories on a large or small scale as may be necessary.
