"Two miles a minute!" breathed Mr. Damon in agreement. "Bless
my wind-gauge! It doesn't seem possible!"

Tom Swift shrugged his shoulders. "It is the impossible that
inventors have to overcome. If we experimenters believed in the
impossible little would be done in this world, to advance
mechanical science at least. Every invention was impossible until
the chap who put it through built his first working model."

"That's understood, old boy," said Ned, already busily
scratching off the form of the contract he proposed to show the
company's legal advisers early in the morning.

When he had read over the notes he had made Tom O.K.'d them.
"That is about as I had the items set down myself on the sheet
that fellow stole from me."

"Wait!" exclaimed Ned, as Tom arose from his chair. "Do you
know what strikes me after your telling me about your second
hold-up?"

"What's that?" asked his chum.

"Are you sure that was the same fellow who stole your wallet?"

"Quite sure."

"Then his second attack on you proves that he got wise to the
fact that your notes were in shorthand. He had a chance to study
them while you visited with Mary Nestor."
