��The Nasal Flute— You Blow Your Soul Into It

GOOD things come slowly, which ex- plains why it required ten years of experimenting on the part of Aurion V. Chevers, of East Providence, Rhode Island, to devise the musical instrument which he is holding to his nose. It is made of wood and consists of a hollow chamber with two holes for the nostrils and one hole for the mouth. Musical sounds are produced with it by blowing through the nose, and the tone and pitch are varied by closing or opening the mouth. In this way many tones can be produced.

���To play the flute, you place it against your nose and breathe as melodically as possible through your nostrils

��A New Type of Hydro-Generator. It Moistens Gas Engine Fuel

THE new type of fuel-moistening de- vice shown in the accompanying broken-away sketch is designed particu- larly for use on trucks. It consists of a special combined intake and exhaust man- ifold, carbureter and water tank. The

��water tank is mounted on top of the en- gine, underneath the hood, and feeds a small amount of water to a special noz7le which is incorporated in the carbureter float chamber.

The carbureter differs from that of conventional design, in that the float chamber and air-in- take are in two sepa- rate pieces, several inches apart, the air-intake having a special bell-mouthed connection with the intake portion of the combined manifold. Between the air-inlet and the throttle valve, a special pipe leads directly to the intake manifold, through which the additional amount of air furnished, is controlled.

The water is sy- phoned from the tank

���into the special fuel nozzle, while the air is fed into the intake manifold through its own inlet. The fuel and water mixture striking the hot exhaust manifold is raised to a high temperature, the water turning into steam as it mixes with the air fed into the cylinders. As pointed out previously in the Popular Science Monthly, the admission of a small amount of steam wath the atomized fuel tends to give greater power and to keep the engine cylinders free from carbon.

��Fuel and water vaporize against the hot manifold. Steam keeps down the carbon

��Canned Music for the Hindus in Their Native Language

AT Calcutta, talking-machine records are made in all the principal lan- guages of India — Hindustani, Tamil, Telugu and Marathi. Though few natives of India, comparatively speaking, are rich enough to buy talking-machines, it is common for companies or individuals to tour the country, giving concerts with the machines. Before the war records in the native languages were— of course- made in Germany, but now they are produced only in India.
