Sub-marine means under the sea.
This boat could be lowered below the surface of the water.
He found a way to supply it with air.
But he could not get it to run swiftly.
It took much money to build such boats.
He tried to get the French government to help him.
He was often tired and disappointed.
But he never stopped trying.
He tried to destroy some large boats.
This was to be done with torpedoes.
But he was not very successful.
He succeeded in destroying one boat.
But since then others have carried out his plan, and torpedoes are often used in war.
This little story is told of Mr. Fulton:--
He was once in New York working upon his torpedoes.
He invited the Mayor and many others to hear him lecture.
They came and were all much interested.
He showed them the copper cylinders which were to hold the powder.
Then he showed them the clockwork, which, when it was set running, would cause the cylinders to explode.
He turned to a case and drew out a peg.
He then said, "Gentlemen, this torpedo is all ready to blow up a vessel.
It contains one hundred and seventy pounds of powder.
The clockwork is now running.
If I should allow it to run fifteen minutes it would blow us all to atoms."
His audience was much frightened.
They all ran away.
Mr. Fulton put the peg back in its place.
He told them it was then safe.
Not until then did they dare come back.
But now our giant, Steam, became the friend of Mr. Fulton.
Many had tried to put this giant to work.
But at first he seemed rather hard to teach.
Long before, a poet had written these lines, which show how much people hoped to make the giant do:--
"Soon shall thy arm, unconquered Steam, afar Drag the slow barge, or drive the rapid car."
It was a true prophecy.
Mr. Fulton married the daughter of a Mr. Walter Livingston.
This Mr. Livingston had a relative who was a great man, and a rich man.
He was much interested in all inventions.
He often helped inventors with his money.
He had long believed that boats could be moved by steam.
At one time the state of New York gave him the right of all steam boats for twenty years.
He was given the right if he would get one steam boat running within a year.
But the year pa.s.sed and the boat was not built.
Everybody made fun of his "grand rights."
At this time our government made him our minister to France.
There he met Robert Fulton for the first time.
And in Paris Mr. Livingston and Mr. Fulton made a steam boat.
When it was finished they invited their friends to come and see it tried.
Early upon the morning when they hoped to succeed, a messenger came.
He bore sad news.
