The ingenious plan by which pebriK.
"a French inventor, measures the distance
az an Invisible vessel depends upon tho
difference IN the velocity Of sound
waves which travel about LOO teet per
second. and OF Hertzian waves tho
passage OF which is practically instan-
tanoous. The receiving htation-which
may be a lighthouse on shore-haa
train Of clockwork that moves pointer
over a dial one division per second. A
sound wave from gun or whistle and
iertzian wave are started simultaue-
ously from the ship. and the Hert4ian
wave sets the ClockWOrk IN motion,
while tho receiving observer notes the
position Of the pointer when the sound
arrives. The number Of divisions pass

receiver necessary could determine Us
