e asked me if I could tell him how to fix a key so that it
would not 'break,' even if the circuit-breaker was open, and also so
that it could not be easily detected. I told him to jab a penful of
ink on the platinum points, as there was sugar enough to make it
sufficiently thick to hold up when the operator tried to break--the
current still going through the ink so that he could not break.

"The next night about 1 A.M. this operator, on the press wire, while
I was standing near a House printer studying it, pulled out a glass
insulator, then used upside down as a substitute for an ink-bottle,
and threw it with great violence at me, just missing my head. It would
certainly have killed me if it had not missed. The cause of the trouble
was that this operator was doing the best he could not to break, but
being compelled to, opened his key and found he couldn't. The press
matter came right along, and he could not stop it. The office boy had
put the ink in a few minutes before, when the operator had turned his
head during a lull. He blamed me instinctively as the cause of the
trouble. Later on we became good friends. He took his meals at the same
emaciator that I did. His main object in life seemed to be acquiring
the art of throwing up wash-pitchers and catching them without breaking
them. About one-third of his salary was used up in paying for pitchers."

One day a request reached the Western Union Telegraph office in Boston,
from the principal of a select school for young ladies, to the effect
that she would like some one to be sent up to the school to exhibit and
describe the Morse telegraph to her "children." There has always been
a warm interest in Boston in the life and work of Morse, who was born
there, at Charlestown, barely a mile from the birthplace of Franklin,
and this request for a little lecture on Morse's telegraph was quite
natural. Edison, who was always ready to earn some extra money for his
experiments, and was already known as the best-informed operator in the
office, accepted the invitation. What happened is described by Adams
as follows: "We gathered up a couple of sounders, a battery, and sonic
wire, and at the appointed time called on her to do the stunt. Her
school-room was about twenty by twenty feet, not including a small
platform. We rigged up the line between the two ends of the room, Edison
taking the stage while I was at the other end of the room. All being
in readiness, the principal was told t
