When I got settled in Paris I struck out to see the Eiffel Tower
station. I found it was just about to be opened and it was my intention
to try to get a job there for I believed it would be the only way I’d
ever get to see the installation.
I asked a _gendarme_, as they call an armed policeman over there, who
was standing hard by, where the office of the wireless station might
happen to be--that is, I asked him in the deaf and dumb alphabet, and I
gathered from the motions he made with his hands and arms that it was in
the underground building. I hied me down the stairs and found myself in
a small, central area-way from which doors around it opened into the
office, receiving, dynamo and sending rooms.
Not being able to read French, as I explained to some officials
afterward, I had carelessly opened the door on which the sign read
_Bureau de Transmitteur_ instead of _Bureau de Telegraphie sans Fil_
with the result that I saw the whole blooming sending apparatus. There
were two operators in charge but they didn’t think I was worth noticing.
The sending apparatus was very much the same as that I saw in the
cableless station at Glace Bay. This is easily explained because there
is only one way to change a large amount of low pressure electricity
such as is generated by an alternating current dynamo into high
potential, high frequency electricity and that way is to use a
transformer to _step up_ the pressure of the alternating current;
condensers are then charged with the latter current and this in turn is
discharged between a pair of spark balls, or a rotary spark-gap which is
used for the same purpose.
Not having been thrown out of the sending room and having seen all there
was to see I opened the door to the _Bureau de Recepteur_ and took a
good look at the receiving apparatus. The detectors were of the
_electrolytic_ type, each of the cups which contained the solution
having three wires sealed in it instead of one; this was the invention
of Prof. Branly of Paris who got up the _coherer_ several years before
Marconi began his experiments in wireless.
The door of the _Installation d’Alimentation Electrique_ was open and I
glanced in at the dynamos, motors and storage batteries and from the
size of its equipment I judged the station to be about 100 horsepower.
Having seen it all I opened the door of the _Bureau de Telegraphie sans
Fil_ and walked in just as we do in offices over here.
Somebody must have told the _Directeur_, or _manager_ as we would call
him in good old English, that I was coming for before I could explain in
sign language that I wanted a job he, with the aid of a couple of other
conspirators, hustled me unceremoniously out, up the stairs and on to
the green grass of the park. No, it wasn’t exactly a case of _sour
grapes_ but after I had seen the apparatus of the station and added it
to my Christian Science collection I didn’t want the job anyway.
