signals may be sent varies according 10 the square
Of tho length Of this conductor. For signalling
eighteen miles he used d conductor eighty feet
high and in his application to NJ. lNckroY he
contender that with a conductor IA feet high he
could establish communication between points on
opposite sides Of the Strait Of Dover and even ten
miles further
His experiments have already proved that when
such vertical wire or conductor. is employed no
hindrarce 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 apparatus fitted up last autumn between
Osborne House. Isle of Wight and the royal yacht
on which the Prince Of Wales was recupcratng
after his accident This gave an opportunity TO
study the effect Of intervening hills and as the
yacht moved about to various positions doubts
were set al rest a. 10 the possibility Of telegraph
ing across long stretches Of land.
