Dr. Kurtz ponderously. "Vy, I vould not efen ride in an outer-mobile,
yet, so vy should I go in von contrivance vot is efen more dangerous?
No, I gomes to your fader in der carriage, mit mine old Dobbin horse.
Dot vill not drop me to der ground, or run me up a tree, yet! Vot?"

"Very well," said Tom, "only hurry, please."

The young inventor, in his airship, reached home some time before the
slow-going doctor got there in his carriage. Mr. Swift was no worse, Tom
was glad to find, though he was evidently quite ill.

"So, ve must take goot care of him," said the doctor, when he had
examined the patient. "Dr. Gladby he has done much for him, und I can do
little more. You must dake care of yourself, Herr Swift, or you
vill--but den, vot is der use of being gloomy-minded? I am sure you vill
go more easy, und not vork so much."

"I haven't worked much," replied the aged inventor. "I have only been
helping my son on a new airship."

"Den dot must stop," insisted the doctor. "You must haf gomplete
rest--dot's it--gomplete rest."

"We'll do just as you say, doctor," said Tom. "We'll give up the
aeroplane matters, dad, and go away, you and I, where we can t see a
blueprint or a pattern, or hear the sound of machinery. We'll cut it all
out."

"Dot vould he goot," said Dr. Kurtz ponderously.
