He thought this a good way to advertise.

He finally bought a good book about electricity.

Soon the bas.e.m.e.nt of the house at Port Huron was filled with many things beside printing presses.

He used stove-pipe wire, and soon had a telegraph wire between the bas.e.m.e.nt and the home of a boy friend.

Perhaps it was a good thing that all the children in the Edison family were not like Thomas.

Had they been, the poor old house would scarcely have held them.

But the mother was proud of all that Thomas did.

She did not worry over the bottles, wires, strings, and printing presses.

About this time Thomas did a brave thing.

The station agent at Mt. Clemens had a baby boy two years old.

This baby crept on to the track in front of a train just coming in.

Quick as thought, young Edison rushed to the track and saved the child at the risk of his own life.

The baby's father was very grateful and offered to teach Thomas telegraphy.

Of course, Thomas was very happy, and accepted the offer.

He came to Mt. Clemens every evening, after working hard all day.

He did so well that, in five months, he was given a position at Port Huron.

He earned six and one-quarter dollars a week.

He worked almost night and day, so that he might learn all he could about it.

His mother said that the world would hear from her boy some day.

Afterwards he worked in several places.

In Indianapolis, though not yet seventeen, he invented his first telegraph instrument.

This was thought to be a great thing for so young a boy to do.

He lost several places because he tried new ways.

At last, he was obliged to walk nearly all the way to Louisville because he had no money.

Here he was given a good position.

He stayed several years.

Under the telegraph rooms was an elegant bank.

One day, while experimenting, he spilled a great bottle of acid.

This acid went through the floor into the bank below.

Of course it spoiled the ceiling, handsome carpets, and furniture.

So the unfortunate inventor had to leave Louisville.

He finally gave up trying to be a telegraph operator.

He opened a little shop.

He invented many things, and kept on thinking.

He could not make his inventions successful, for he had little money.

He thought so hard that he forgot everything else.

Once he was asked to speak before a company.

He forgot all about it.

They sent for him, and found him at the top of a house putting up a telegraph line.

He went in his working clothes to make his speech.

He felt queer when he found a room full of elegant ladies.

But he made a good speech.

Then he went to New York.

There he walked the streets three weeks, looking for work.

n.o.body wanted a man who experimented.

By chance, he one day went into an office where the telegraph instrument was out of repair.

He offered to fix it.

They laughed at him, but let him try.

He succeeded in fixing it.

They gave him a good position.
