London, March 29.-Gulielmo Mar
conf. the inventor. who recently after
long delay obtained permission from the
French government to establish a sta
ton on the French coast for the pur-
pose of experimenting with wireless
telegraphy between England and
France, announces that he has con-
Quoted successful experiments between
the South Foreland. county Of Kent,
and Boulogne, at the mouth of the
Lianne
The Times this morning prints hun
dred word dispatch, the first press mes
sage by the Marconi system of wireless
telegraphy describing the experiments
between the South Foreland and Bou-
logne. The experiments were conducted
with the Morse code, which was read
as distinctly as if the terminil had been
connected with wires.
The South F'oreland is the most cas-
terly land in England, consisting of a
chalky cliff about 200 feet in height.
projecting into the North Sea, and hav-
ing two light houses, with an eleva
ton of 372 feet Signor Marconi's sys-
tenn of wireless telegraph has been in
practical operation off the English
South Foreland lighthouse and the East
Goodwin lightship, g. distance of -
miles. The distance from South Fore
land to Bouiogne sur Mer is 80 miles,
the greatest previous distance covered
having been IS miles, between Pn<le
and Bournemouth in England. An ex-
perience of IA months had shown him
that no kind of weather would stop the
working of his apparatus. The vertical

of his system and he has found that
the distance to which signals may be
sent varies according to the square of
the length of this conductor. For sig
Mailing IS miles he used a conductor so
feet high and in his application to NJ
Lockroy he contended that with a con-
ductor ia feet high he could establish
communication between points on OPP
posite sides of the strait of Dover and
even go that distance 10 miles better.
His experiments have already proven
that when such vertical wire or con-
ductor is employed no hindrance to
signalling is caused by hills or other
obstacles, or by the curvature of the
earth. One of his most interesting and
valuable experiments was the installa-
ton fitted up last autumn between Os-
borne house, Isle of Wight, and the
royal yacht on which the Prince Of
Wales was recuperating after his ac-
cident. This gave an opportunity to
study the effect of intervening hills,
and as the yacht moved about to vari-
Gus positions, doubts were set at rest
as to the possibility of telegraphing
across long stretches of land Commu-
nication between lightships and shore
Is matter of great Importance and
the wireless system between South
Foreland lighthouse and East Goodwin
lightship worked through the fiercest
storms Of the latter part of February
without interruption, the messages be-
ing flashed continually from ship to
shore and vice versa.
Signor Marconi Is much the most sue
cessful experimental among the many
who have worked along the same lines
He is now in his 18th year He is an
Italian and it was in Italy that he be-
gan his especial work The Italian
government paid him a large sum of
money for his invention to be used on
warships. From Italy he went to Eng
land and his success has already in
terested Emperor William, who has in
structed experts to experiment with
the wireless system for the benefit of
the German army and navy.
He recently, in the course of a lee
ture on the system. illustrated its pr1n-
ciple by likenng it to that upon which
a tuning fork will respond to vibra-
tions caused by striking another tun-
ing fork near it,
