The Boundless Prospect

Take a square box, about six inches long and twelve high, or of any

other proportionate dimensions. Cover the inside with four flat pieces

of looking-glass placed perpendicular to the bottom of the box. Place

at the bottom any objects you please, as a piece of fortification, a

castle, tents, soldiers, &c. On the top, place a frame of glass shaped

like the bottom of a pyramid, as in Fig. 8, and so formed as to fit on

the box like a cover. The four sides of this cover are to be composed

of ground glass, or covered inside with gauze, so that the light may

enter, and yet the inside be invisible, except at the top, which must

be covered with transparent glass: when you look through this glass,

the inside will present a pleasing prospect of a boundless extent;

and, if managed with care, will afford a deal of amusement.
