USES ACETYLENE IN FOREST
Foresters Utilize it to Flash Messages by Morse Telegraph Code.
The new acetylene signal lantern used in the national forest service for signaling by the Morse telegraphic code works so successfully that messages can be read by the naked eye at a distance of nineteen miles when good binoculars were used at the receiving station.
The gas is produced by the ordinary carbide and water, and the tank which is adjustable to the back of the lantern, is sufficiently large for about three hours of signaling.
When burning normally only enough gas is admitted to the lantern to maintain a minute flame, but when the controlling key is depressed the gas aperture is enlarged and the flame flares up instantly, producing a dash, which continues so long as the key is kept depressed. The dots and dashes of the Morse code are thus produced by manipulation of the key.
