Materials Required:—

A piece of thin cardboard fifteen or eighteen inches square, gummed paper or thin tape, paste or mucilage, scissors.

This is made of a piece of cardboard about fifteen inches square. Insert a pair of compasses at one corner, and from the one corner to that diagonally opposite describe a part of a circle and cut along the line marked. Now bend the cardboard over into a conical trumpet shape, and overlap the sides where they join, about an inch. Lay over this join a broad strip of cloth or paper pasted or glued firmly; you can put pins through the cardboard till this is set into place and dried. Now at the pointed end of the cone cut a mouthpiece wide enough to speak easily into; this will need a hole about three inches wide. When you speak into this megaphone your voice will carry a long distance—a quarter of a mile on a quiet evening—and it will give great fun to watch the effect on people who are walking at some distance in the country. For convenience in holding you can paste on to the outside a loop or handle of tape, but do not push this through the cardboard as it is important that there should be nothing projecting inside the trumpet of the megaphone.
