LIGHTS AND SHADES.
If you wish to throw the background of a tableau in shade, intervene screens between the lights at the sides of the stage and that part of the picture you desire to have dark; vice versa with the foreground. Particular points or characters can be more brilliantly lighted than others by placing at the side of the stage a strong light within a large box, open at one side, and lined with bright reflectors. Light of different colors can be thrown successively on a picture, and made to blend one with another, by placing the various colored fires in boxes three feet square, open at one side, and lined with bright reflectors; these, arranged at the side of the stage on pivots, can be turned on, one after another, so as to throw their light on the stage. Before one light has entirely vanished from the scene, a different color should gradually take its place.
