His Best Previous Work.
The distance between South Fore
land lighthouse to BonIogne is thirty
two miles, the greatest previous
eighteen miles between Poole and
Bournemouth, in England. An ex-
perience of fourteen months had
shown him that no kind of weather
would stop the working of his appn-
ratus. The vertical conductor he uses is
the main feature 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 con
ductor. For signaling eighteen miles
he used a conductor eighty feet high
and in his application to N. Lockroy
he contended that with a conductor
LA feet higher he could establish com
m%unication between points on opposite
sides Of the strait of Dover and even
ten miles further.
His experiments have already proved
that when such a vertical wire or CON
ductor is employed no h%indrance to
signaling is caused by hills or other
obstacles or by the curvature of the
earth. One of his most valuable ex-
periments was the installation fitted
up last autumn between Osborne
house, Isle of Wight, and the royal
Yacht on which the prince of Wales
vas recuperating after his accident.
Tais gave an opportunity to study the
effect of intervening hills, and as the
yacht moved about to various positions
doubts We're set at rest as to the posi-
bility of telegraphing across long sec
tons of land. Communication be-
tween light ships and shore is a matter
of great Importance, and the wireless
system between South Foreland light
house and East-Goodwin lightship
worked through the fierce storms of
the latter part of February without in
terrnption, the messages being flashed
continually from ship to shore and vice
versa.
