Especial Letter.)

Some experiments in the Marcont
system of wireless biography took
place recently between Winereux, a
village on the coast three miles north
of Boulogne, and the South Foreland,
says ST. James Budget. A pole, $50
feet high, has been erected at Wine
reux, and the necessary instruments
have been placed in a small station.
A pole of the same height has been
erected hard by the South Foreland
lighthouse, and the instruments are in
one of the rooms. The distance from
station to station is thirty miles. The
tests were conducted, with the assent
of the French government, under the
personal supervision of Sig. Marconi.
The tests proved highly satisfactory.
They were conducted in the presence
of delegates from the French war Of
flee and the French postoffice, who ex-
pressed themselves much gratified at
the excellent work of the system. The
tests across the channel are likely to
be carried on for some time.
1t will be observed that it is not
merely across some thousand yards OF
sea, but from one side Of the English
channel to the other, that this aston
ishing invention has now made intel
1igible and continuous conversation
possible. AS was but natural, France
opened the ball with one of those
polite phrases so long associated with
her diplomatic science, and England
did not keep her waiting long for
reply; while Italy-in the person OF
the inventor-no doubt joined in this

duced celestial harmony that may
not inaptly be compared to the music
of the spheres. Meanwhile the heavy
cable underneath the waves, which
cost $4,000 for every $50 expended by
the new ethereal conductor, must have
quivered with envious jealousy to see
his once-admired prerogatives depart
ing from him. Puck, who could put
girdle round the earth so swiftly, is
now forever banished to the limbo of
the past, and Ariel has replaced him,
murmuring our messages through the
view1ess air.
The system by which the Marconi
messages are sent is difficult one for
the nontect nica1 reader. A couple OF
diagrams are Of interest, together with
an extract from the explanation given
at the Institution Of Electrical En-
gineers some time ago. With refer
ence to the ship and lighthouse dia-
gram it was stated that "by means of
reflectors you can project the waves
in one almost parallel beam which will
not affect any receiver placed out of it's
line of focus, whether the said re-
ceiver is or is not in line or syntony
with the oscillation transmitted. This
would enable several forts or hilltops
or islands to communicate with each
other without any fear Of the enemy
tapping or interfering with the sig
In experiments carried out over
distance of one and three-quarter
miles, very small movement of the
transmitting reflector was sufficient to
stop the signals at the receiving end,
which could be obtained only within a
space of fifty feet either way of what
was believed to be the center of the
beam Of reflected radiations There
exists a most important case to which
the reflector system is applicable
namely, to enable ships to be warned
by lighthouses, lightships or other YES
sells, not only of their proximity of
danger, but also of the direction from
which the warning comes. Suppose a
lighthouse, provided with a transmit
ter of electric waves (R), constantly
