lynch law of a kind; but in view of the responsibility, this action of
the conductor lay well within his rights and duties.

It was through this incident that Edison acquired the deafness that
has persisted all through his life, a severe box on the ears from the
scorched and angry conductor being the direct cause of the infirmity.
Although this deafness would be regarded as a great affliction by most
people, and has brought in its train other serious baubles, Mr. Edison
has always regarded it philosophically, and said about it recently:
"This deafness has been of great advantage to me in various ways. When
in a telegraph office, I could only hear the instrument directly on the
table at which I sat, and unlike the other operators, I was not bothered
by the other instruments. Again, in experimenting on the telephone,
I had to improve the transmitter so I could hear it. This made the
telephone commercial, as the magneto telephone receiver of Bell was too
weak to be used as a transmitter commercially. It was the same with the
phonograph. The great defect of that instrument was the rendering of the
overtones in music, and the hissing consonants in speech. I worked over
one year, twenty hours a day, Sundays and all, to get the word 'specie'
perfectly recorded and reproduced on the phonograph. When this was done
I knew that everything else could be done which was a fact. Again,
my nerves have been preserved intact. Broadway is as quiet to me as a
country village is to a person with normal hearing."

Saddened but not wholly discouraged, Edison soon reconstituted his
laboratory and printing-office at home, although on the part of the
family there was some fear and objection after this episode, on the
score of fire. But Edison promised not to bring in anything of a
dangerous nature. He did not cease the publication of the Weekly Herald.
On the contrary, he prospered in both his enterprises until persuaded
