the ingenious mechanism which reads and registers the beating of the
financial pulse.

Edison came first to New York in 1868, with his early stock printer,
which he tried unsuccessfully to sell. He went back to Boston, and quite
undismayed got up a duplex telegraph. "Toward the end of my stay in
Boston," he says, "I obtained a loan of money, amounting to $800, to
build a peculiar kind of duplex telegraph for sending two messages over
a single wire simultaneously. The apparatus was built, and I left
the Western Union employ and went to Rochester, New York, to test the
apparatus on the lines of the Atlantic & Pacific Telegraph between that
city and New York. But the assistant at the other end could not be made
to understand anything, notwithstanding I had written out a very minute
description of just what to do. After trying for a week I gave it up and
returned to New York with but a few cents in my pocket." Thus he who
has never speculated in a stock in his life was destined to make the
beginnings of his own fortune by providing for others the apparatus
that should bring to the eye, all over a great city, the momentary
fluctuations of stocks and bonds. No one could have been in direr
poverty than he when the steamboat landed him in New York in 1869. He
was in debt, and his few belongings in books and instruments had to
be left behind. He was not far from starving. Mr. W. S. Mallory, an
associate of many years, quotes directly from him on this point: "Some
years ago we had a business negotiation in New York which made it
necessary for Mr. Edison and me to visit the city five or six times
within a comparatively short period. It was our custom to leave Orange
about 11 A.M., and on arrival in New York to get our lunch before
keeping the appointments, which were usually made for two o'clock.
Several of these lunches were had at Delmonico's, Sherry's, and other
places of similar character, but one day, while en route, Mr. Edison
