experiments on the 11th inst. with a view to testing the distance
to which it was possible to signal without wires with the
apparatus presently at my command, viz: a six-inch spark coil as
a transmitter, and unexhausted coherers, made in our own

slow steam, the distance was gradually increased, communication
being kept up all the time until, at about three quarters of a
mile, the coherers failed to respond. Careful tests were made,
and all possible variations of spark length tried, but no
effective waves could be detected outside the three quarter mile
radius. By means of flag signals, the launch was instructed to
return slowly, and immediately it entered the magic circle, t h

through the scientific papers could, in a month, attain the
perfection of detail that has taken Mr.Marconi, assisted by some
of the cleverest electricians in England, Five years to
accomplish. . . . The results were not as
satisfactory as I
had anticipated, but were quite sufficient to confirm me in my
opinion that with proper appliances, the system would be quite
reliable, and meet all the requirements for conveying shipping
intelligence to and from Rottnest.TO PUT THINGS IN PERSPECTIVE,
Marconia had succeeded in sending Wireless Telegraphy about 20
miles, to successfully span the ENGLISH CHANNEL in March that
year, and nearer home, the CITY OF YORK had sunk off Rottnest
with the loss of 12 lives during a storm.Communication at the
time was by coloured flags to the Port of
FREMANTLE.
