Edison, Thomas A. (Thomas Alva), 1847-1931; Inventors -- United States -- Biography
The test under these more favorable circumstances was a success. "The
record was as perfect as copper plate, and not a single remark was made
in the 'time lost' column." Edison was now asked if he thought he could
get a greater speed through submarine cables with this system than with
the regular methods, and replied that he would like a chance to try
it. For this purpose, twenty-two hundred miles of Brazilian cable then
stored under water in tanks at the Greenwich works of the Telegraph
Construction & Maintenance Company, near London, was placed at his
disposal from 8 P.M. until 6 A.M. "This just suited me, as I preferred
night-work. I got my apparatus down and set up, and then to get a
preliminary idea of what the distortion of the signal would be, I sent a
single dot, which should have been recorded upon my automatic paper by
a mark about one-thirty-second of an inch long. Instead of that it was
twenty-seven feet long! If I ever had any conceit, it vanished from my
boots up. I worked on this cable more than two weeks, and the best I
could do was two words per minute, which was only one-seventh of what
the guaranteed speed of the cable should be when laid. What I did
not know at the time was that a coiled cable, owing to induction, was
infinitely worse than when laid out straight, and that my speed was as
good as, if not better than, with the regular system; but no one told me
this." While he was engaged on these tests Colonel Gouraud came down
one night to visit him at the lonely works, spent a vigil with him, and
toward morning wanted coffee. There was only one little inn near
by, frequented by longshoremen and employees from the soap-works and
cement-factories--a rough lot--and there at daybreak they went as soon
as the other customers had left for work. "The place had a bar and six
bare tables, and was simply infested with roaches. The only things
that I ever could get were coffee made from burnt bread, with brown
molasses-cake. I ordered these for Gouraud. The taste of the coffee, the
insects, etc., were too much. He fainted. I gave him a big dose of gin,
and this revived him. He went back to the works and waited until six
when the day men came, and telegraphed for a carriage. He lost all
interest in the experiments after that, and I was ordered back to
America." Edison states, however, that the automatic was finally adopted
in England and used for many years; indeed, is still in use there. But
they took whatever was needed from his system, and he "has never had a
cent from them."
