feet and a half in height between the top and bottom strips which form the frame; the width, four feet, the same as the distance between the two smaller frames ; and the bottom strip two feet and a half above the floor."

When this is completed, it will present the appearance of a large frame between two smaller ones.

Cover all the space above and below the frames with cloth of the same color as that upon the back-wall, so that the frames will appear to be hanging upon the wall.

Behind the frames, erect a platform two feet and a half above the floor, upon which the performers are to stand.

If gas is available, fasten a rod, with burners upon it, over the top of the curtain or folding-doors. The best way is to make for it a shelf supported upon two posts about eight feet high. Over the burners, and behind them, tack sheets of common tin, bent so as to throw the light down. If you cannot get the tin conveniently, fasten behind the burners a white sheet, which will serve the purpose very well. If the curtain does not come to the ceiling, a shawl or thick cloth must be put above it, so that the light cannot show over the curtain into the darkened room where the audience sit. When gas cannot be had, and kerosene-lamps are used, holes must be made in the board to fasten them firmly in their places.

Next make a veil of black tarlatan-muslin large enough to cover the space before the folding-doors or posts which support the curtain.

The construction of the frames will be clearly understood by examining the diagram on the next page, in which all the details of measurements, and the relative positions of the frames, are very plainly exhibited in skeleton form, previous to applying the covering, which hides all of the construction except the three picture-frames.
