This was made up of low frequency transformers, revolving spark-gaps
which changed the high pressure alternating currents into high frequency
electricity. Then there were the high pressure oscillation transformers,
the condensers and switches of large size which were actuated by
telegraph sending keys. Yes, indeed, here were the real sights of a
cableless station and it was fully worth all that my round voyage cost
me to see it. Having feasted my eyes on this greatest of twentieth
century wonders to my heart’s content we went outside to get a
_close-up_ of the aerials.
“You see, Jack, we have two separate and distinct aerial wire systems.
The first, which is strung up between the four great towers is used only
for sending and the second which is suspended from the sticks is used
only for receiving. These latticed towers are built of wood and each one
is 410 feet high and together they form a square each side of which is
220 feet across.
“The sending aerial is formed of a large number of nearly parallel wires
all of them spread out at the top and coming together at the bottom like
an inverted pyramid. This aerial which has 60,000 feet of wire in it was
suspended from the tops of the towers. A leading-in wire is secured to
the ends of all the aerial wires where they come together at the bottom.
It leads, as you see,” he pointed to the side of the building, “into the
room through insulators where it is connected to the rotary spark-gap
through a closed circuit.
“These masts, or sticks, which are arranged in three rows, hold up the
receiving aerials. There are 18,000 feet of wire in it and it is made in
the shape of a fan with the handle pointing in the direction of Clifden
where our other station is located.”
Before leaving Howard told me that when he heard the _Marconi Company_
intended to build a pair of cableless stations it was his great ambition
to be one of the operators and in getting this position he had realized
it. For myself I preferred to go on making my collection of cableless
stations rather than to be planted up there at Glace Bay even though
this was one of the three places in the world where the overland
telegraph lines and transatlantic cableless meet and form a clearing
house for the news of two continents.
It was my intention to sail for Belfast, Ireland--all the big steamers
touch at that port on their way from New York to Liverpool--and go over
to Clifden to see the cableless station there. Before leaving, however,
I got it straight from Mr. Bottomley, who was the President of the
American _Marconi Company_, that it was built from the same plans as the
one at Glace Bay and that the apparatus was exactly the same, I
concluded not to bother adding it to my collection but to go to Paris
direct and get the Eiffel Tower station instead.
