ry me!' he said. 'All right, I will give you $60
per week to run both shifts.' He went at it. His executive ability
was greater than that of any other man I have yet seen. His memory was
prodigious, conversation laconic, and movements rapid. He doubled
the production inside three months, without materially increasing the
pay-roll, by increasing the cutting speeds of tools, and by the use of
various devices. When in need of rest he would lie down on a work-bench,
sleep twenty or thirty minutes, and wake up fresh. As this was just what
I could do, I naturally conceived a great pride in having such a man in
charge of my work. But almost everything has trouble connected with it.
He disappeared one day, and although I sent men everywhere that it was
likely he could be found, he was not discovered. After two weeks he came
into the factory in a terrible condition as to clothes and face. He sat
down and, turning to me, said: 'Edison, it's no use, this is the third
time; I can't stand prosperity. Put my salary back and give me a job.' I
was very sorry to learn that it was whiskey that spoiled such a career.
I gave him an inferior job and kept him for a long time."
Edison had now entered definitely upon that career as an inventor which
has left so deep an imprint on the records of the United States Patent
Office, where from his first patent in 1869 up to the summer of 1910
no fewer than 1328 separate patents have been applied for in his name,
averaging thirty-two every year, and one about every eleven days; with a
substantially corresponding number issued. The height of this inventive
activity was attained about 1882, in which year no fewer than 141
patents were applied for, and seventy-five granted to him, or nearly
nine times as many as in 1876, when invention as a profession may
be said to have been adopted by this prolific genius. It will be
understood, of course, that even these figures do not represent the full
measure of actual invention, as in every process and at every step there
were many discoveries that were not brought to patent registration, but
remained "trade secrets." And furthermore, that in practically every
case the actual patented invention followed from one to a dozen or more
gradually developing forms of the same idea.
An Englishman named George Little had brought over a system of automatic
telegraphy which worked well on a short line, but was a failure when put
upon the longer circuits for which automati
