HOW TO MAKE AN HARMONICON.

| Of some good wood—say pine, which is very suitable for thf purpose—make a box without top about fourteen inches long and twe inches deep, varying in width frott • 3in. at one extremity to sin. at the other. Half-inch should be the thickness of the wood. Two lengths ol narrow tape should next be stretched from end to end of the box for the purpose of supporting slips of glass whose vibrations produce thr

musical notes. r . moat be parallel with and Jia. «in»*»r.t from the sides, and sho.i d hi secured by small nails. Take a ♦having from the top of each end piic«, so that th* tapes may lie this distanc* 'below th# top of the box. Next cut yo»r gl*s» slips an inch wide, but of varying lengths, to fit the vary ini |«WthS of the box. Tna thinnest glass alone is suitable. Place on the upcs and tunc to the desired musical note ; this must be done by carefully chipping bits off the corners by means of a Pair of pincers. It need scarcely be sai't that this is an operation ol some nicety, but it must bo undertaken if the barmonicon is to be of any practical use. As the bass, or the wide end, is approached, the glass should increase the slightest imaginable degree in thickness. The tuning satisfactory, glue the slips to the tape. Lastly, add four lengths of wood Jin. thick to the top of the box to conceal the ends of the glass slips, and paint or varnish or decorate as fancy may suggest. Two little blocks of cork glued to strips of light wood about 6in. long will serve for the hammers with which the instrument ,is played.
