4 All About Inventions
l Naturally these achievements aroused intense in-
terest among those to whom the results were commu-
nicated. And when Marconi repeated the experiments
in the laboratory, to the satisfaction of Sir William
Preece and other scientists, they were received with
such emphatic favour that it was decided to carry out
further trials without delay in the open air. Ihe com-
parative security of Salisbury Plain was selected as
the most favourable spot, and here the results were re-
peated without the slightest interference or publicity.
«But these trials proved additionally remarkable, be-
cause it was found possible to send the signals through
houses, hills, and other obstacles with as much facility
as over a stretch of the open level plain.
Moreover, the influence of the height of the capacity
above the ground upon distance was brought home
very strikingly, and forthwith it was decided to
determine how far such signals might be sent with
the instruments available. In order to elevate
the capacity to a sufficiently imposing height weird
fand novel efforts were made. Tiny balloons covered
with tinfoil, and kites of varying forms and design,
similarly covered with tinfoil, were sent aloft, a thin
wire being used instead of the conventional string,
and connected to the instruments upon the ground
below. This work proved somewhat exasperating,
because the fickle Clerk of the British Weather would
persist in intervening, and appeared to be striving
desperately to thwart the realisation of the young
Italian’s dream. Balloon after balloon was wrenched
free and hurried away in mad glee by the boisterous
winds, never to be seen nor heard of again. Kites
were ripped, torn, and smashed by the same rebellious
