Baxter. He did not believe the men recognized him as the
person who had been at the Meadow Inn one day with Mary. They had
hardly glanced at him then, he thought.

"That's a mighty powerful extinguisher you have there, young man," said
Melling. "May I ask the make of it? We ought to carry one like it on
our car," he told his companion.

"It is the Swift Aerial Fire Extinguisher," said Tom gravely, with a
glance at Mr. Damon.

"The Swift--Tom Swift?" exclaimed Melling. "Do you mean--"

"I am Tom Swift," put in the young inventor quickly. "And this is one
of my inventions. I might add," he said slowly, looking first Melling
and then Field full in the face, "that I was aided in perfecting the
chemical extinguisher by Josephus Baxter."

The effect on the two men, whom Tom believed were scoundrels, was
marked.

"Baxter!" cried Field.

"Is he associated with you?" demanded Melling.

"Not officially," Tom answered, delighted at the chance to "rub it in,"
as he expressed it later. "I have been helping him, and he has been
helping me since he lost his dye formulae in--in your fire!"

"Does he say he lost them in the fire of our factory?" demanded Field
aggressively.

"He believes he did," asserted Tom. "I helped carry him out of the
laboratory of your place when he was almost dead from suffocation. He
remembers that he had the formulae then, but since has been unable to
find them."

"He'd better be careful how he accuses us!" blustered Field, in his big
voice.

"We could have the law on him for that!" squeaked the bigger Melling.

"He hasn't accused you," said Tom easily. "He only says the formulae
disappeared during the fire in your place, and he is just wondering,
that is all--just wondering!"

"Well, he--we, I--that is, we haven't anything from Baxter that we
didn't pay for," declared Field. "And if he goes about saying such
things he'd better be careful. I am going--"

But he suddenly became silent as his companion's elbow nudged him. And
then Melling took up the talk, saying:

"We're much obliged to you, Mr. Swift, for putting out the fire in our
car. But for you it would have been destroyed. And if you ever want to
sell the extinguisher process of yours, you'll find us in the market.
We are going into the dye business on a large scale, and we can always
use new chemical combinations."

"My extinguisher is not for sale," said Tom dryly. "Come on, Mr. Damon.
We can take you into town, I suppose," Tom
