flight. Come! there's no danger."

"I--I almost believe I will," she said hesitatingly. "Will you take me
down when I want to come?"

"Of course," said Tom. "Get in, and we'll start."

The Humming-Bird was all ready for a trial flight, and Tom was glad of
the chance to test it, especially with such a pretty passenger as was
Miss Nestor.

"Bless my shoelaces!" cried Mr. Damon. "I can see where I am going to be
cut out, Tom Swift. I'll not get many more rides with you now that Miss
Nestor is taking to aeroplaning, you young rascal!" And he playfully
shook his finger at Tom.

"Oh, I don't expect to get enthusiastic over it," said Miss Nestor, who,
now that she had taken her place in one of the small seats under the
engine, appeared as if she would be glad of the chance to change her
mind. But she did not.

"Now, if you take me more than five feet up in the air, I'll never speak
to you again, Tom Swift!" she exclaimed.

"Five feet it shall be, unless you yourself ask to go higher," was the
youth's reply, as he winked at Mr. Damon. Well he knew the fascination
of aeroplaning, and he was almost sure of what would happen. "You can
take a tape measure along, and see for yourself," he added to his fair
passenger. "The barograph will hardly register such a little height."
