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.
