boys' interests.

Early in the evening the hall was filled to overflowing, and ushers were
appointed to seat the crowd. Naturally there was much chattering and
scraping of feet until suddenly a strain of music, an orchestral
selection, began to come out of the horn and there was instant quiet.
After its conclusion came the voice:

"This is our last lecture on Edison. Following this will be given a
series on Marconi, the inventor of the wireless.

"As I have told you, Mr. Thomas Alva Edison's leap to fortune was sudden
and spectacular, as have been most of his accomplishments since. Those
who do really great things along the lines of physical improvement, or
concerning the inception of large enterprises are apt to startle the
public and to surprise thoughtful people almost as though some
impossible thing had been achieved.

"From a mere salaried operator to forty thousand dollars in a lump sum
for expert work was quite a jump.

"The forty thousand dollars, however, did not turn Mr. Edison's head as
has been the effect of sudden wealth on many a good-sized but smaller
minded man.

"He used it as a fund to start a plant and hire expert men to experiment
and work out the inventions which came to him so fast in his ceaseless
work and study. He could get along with as little sleep as Napoleon is

while cannon were booming all around him.

"There was something Napoleonic, also, about Edison's intensity of

genius is the ability to take great pains, Thomas A. Edison is the
greatest genius in the world to-day--if not in all history.

"Sometimes, as Napoleon did with his chief generals before a decisive

coworkers. Sometimes he and they would neither eat nor sleep till they
had fought out a problem of greater importance to the world than even
Napoleon's crossing the Alps or the decisive battle of Austerlitz. But,
though he began to work on a large scale, young Edison's financial
facilities were of the crudest and simplest.

"Almost all of his men were on piece-work, and he allowed them to make
good salaries. He never cut them down, although their pay was very high
as they became more and more expert.

"Instead of _books_ he kept _hooks_--two of them. All
