THE WOODEN HARMONICON.
On a firm stand erect a three-inch soft wood board, a yard high and half a yard broad, in which stand twenty deal rods. The longest should be about five feet. The ones representing semi-tones should be painted a different colour from the others, which can be left plain.
Rub the fingers in rosin-dust and set the rods vibrating with friction, and you will have a manageable instrument, sweet and expressive.
