means Of hempen rope, and are braced
apart by a needle or spar Of wood. The
wireless telephone, just as the wireless
telegraph, depends upon the projection OF
electric waves that pass through the at
.mosphere, and solid substances as well,
with the velocity OF light, which is 100000
miles a second or more than seven timea
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 forma-
tion 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. Tels-
phony Is the art OF translating 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, as
only the air vibrations can be measured
by the ear. In the wireless telephone
the air waves are translated into ths
vibration Of an electrical discharge
which oscillates the ether.
one exceptionally valuable feature OF
the wireless telephone which the United
States Government is utilizing as rapidly
as possible, Is its adaptabillty to the
lighthouse and lightshp service. Because
OF the absence OF wire maintenance
charges It costs no more TO talk from
shore to a lighthouse or a lishtshlp than
II would cost to talk between two blocks
OF a congested city district ana the light
house keeper or lightship people need
have no expert training in order to oper-
ate the apparatus.
Government shows It's Appreciation.
At every turn the Government has
shown its appreciation OF the invention,
which, in addition to having been I'm
stalled on the thirty odd battleships.
cruisers and torpedo-boat destroyers of
the Pacific fleet before they started on
their voyage around the world. has also
been installed at Fortress Monroe, Mare
Island and other army posts.
| Stlll 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 TO
passengers travelling on the passenger
vessels. A service OF this kind, aided by
a huge receiver so that all OF the passen-
gers gathered In a large salon could hear
the music or operate airs slmultane-
ously, should prove most welcoms
innovation for steamship travellers. II Is
within the range OF possibilities, at an
early date, that the traveller by Great
Lakes steamer may be able to spend his
evenings listening 20 the voices OF caruss
or Melba simultaneously with the audien-
ces who see the singers in person at
Covent Garden, London, or the Metro
polltan or Manhattan opera Houses in
New York.
With the first great long distanes
wireless station nearing completion at
Toledo, with twenty-five other long dis
tance stations already contracted far
construction along the lake front, with
work going ahead on seventy-five small
er shore stations and with fifty odd more
already projected, there is reason 20 ex-
pect that by the time Great Lakes naVi-
cation opens in the Spring for the season
OF 1903, the wireless telephone system
will be in full operation on the Great
Lakes with nearly 200 stations In use.
The central station OF the system will
be located at Sault ste Marie, a contract
for its construction already having been
let, Chicago, Cleveland, Detroit, Mllwau-
See, Duluth, Buffalo, Erie and Plttsburg
are among the cities being provided with
long-distance stations, while among other
