LoNoON, March 2S.-GugliOlmO
Marconi, the inventor, who recently.
after long delay, obtained permission
from the French Government to estab-
hsh station on the French coast for
the purpose of experimenting with
wireless biography between England
and France, announced that he has
conducted successfully experiments be-
tween the South Foreland, county of
Kent, and Boulogne
The Times this morning prints a
hundred-word dispatch, the first, press
message by the Marconi system of
wireless telegraphy, describing the ex-
periments between the South Foreland
and Boulogne. The experiments We're
conducted with the Morse code, which
was read as distinctly as if the termini
had been connected with wires
The South Foreland is the most east
erly land in England, consisting of a
chalky cliff about 200 feet in height,
projecting into the North sea and hav-
ing two lighthouses, with an elevation
of 372 feet. Marconi's system of wire
less biography has been in practical
operation off the English coast for sew
eral months between the South Fore
lightship, a distance of twelve miles.
The distance from South Foreland
lighthouse to BoulogneSu Mer is thir-
ty-two miles, the greatest previous dis
lance covered having been eighteen
miles, between Poole and Bourne
mouth, in England. An experience of
fourteen months had shown that no
kind of weather would stop the work
ing of the apparatus. The vertical con-
ductor Marconi used is the main feat
ure 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
signaling eighteen miles he used con-
ductor eighty feet high, and in his ap-
plication to M. Lockroy, he contended
that with conductor ia feet high he
could establish communication between
points on opposite sides of the Strait
of Dover and even go that distance ten
miles better
HIS experiments have already proved
that when such vertical wire or con-
ductor is employed, no hindrance to
signaling is caused by hills or other
obstacles or by the curvature of the
earth.
Communication between lightships
and shore is a matter of great impor-
lance and the wireless system between
South Foreland lighthouse and East
| Goodwin lightship worked through
the fierce storms of the latter part of
February without interruption, the
messages being flashed continually
from ship to shore and vice versa
Signor Marconi is much the most
successful experimental among the
many who have worked along the
same lines. He is now in his twenty
sixth year. He is an Italian and it was
in Italy that he began his special work
The Italian Government paid him a
large sum of money for his invention,
to be used on warships. From Italy he
went to England and his success there
has already interested Emperor Will
lam, who has instructed German eX-
perts to experiment with the wireless
cI-c of hn
army and navy. He recently, in the
course Of a lecture on the system, il
lustrated its principle by likening it to
that upon which a tuning fork will re-
spOnd to vibrations caused by striking
another tuning fork near it.
