wireless telephone, Just as the wireless
telegraph. depends upon the projection Of
electric waves that pass through the at
nnosphere, and solid substances as well.
with the velocity OF light, which is 10000
miles second or more than seven times
the circumference OF the globe.
The mechanical principles upon which
the wireless telephone depend seem to
be simple enough. although there is q
great difference OF opinion as to the act
ual explanation OF the phenomena OF
wireless telephony. Speech Is the for7na-
ton OF very rapid complex and ever-vary-
ing series OF vibrations OF the air ana
their measurement by the nerves OF the
ear. Owing to the resistance Of the at
mosphere. these vibrations grow weaker
and at last disappear as we get further
from the source OF disturbance. Tela-
phony is the art Of transfating these
vibrations OF the air into vibrations OF
ether whose Lesser resistance enables
them to be carried to great distances for
translation into air vibrations again, az
only the air vibrations can be measured
by the ear, In the wireless telephone
the DIR waves are translated into tbs
vibration OF an electrical discharge
which oscilates the ether.
One exceptionally valuable feature OF
the wireless telephone. which the United
States Government is utilizing as rapidly
as possible, IS It's adaptsbIlity to tho
lighthouse and lIghtshIn service. Because
OF the absence OF wire maintenance
charges Il costs no moro to talk from
shore TO lighthouse or Ightship than
1t would cost 10 talk between two blocks
OF congested city district. and the light
house keeper or lightship people need
have no expert training in order to oper-
ate the apparatus.
Government shows It's Appreelntion.
At every turn the Government has
shown its appreciation OF the invention.

stalled on tho thirty odd battieships.
cruisers and torpedo-boat destroyers Of
the Pacific feet before they started on
their voyage around the world, has also
been installed at Fortress Monroe, Mare
Island and other army posts.
Still another feature Of the invention,
or rather the benefit that may be derived
from it, is for the supplying Of music
and other forms Of entertainment ID
passengers travelling on the passenger
vessels. A service OF this kind, aided bv
huge receiver so that all Of the passen-
gers gathered in a large salon could hear
the music or operate airs simultane-
ously. should prove most welcome
innovation for steamship travellers. n q
within the range Of possibilities, az an
early date, that the traveller by Great
Lakes steamer may be able to spend his
evenings listening to the voices OF Caruse
or Melha simultaneously with the audien-
ces who see the singers In person AZ
