Waterford in a jiffy," said Tom, and he kept his word, for the speedy aeroplane carried him and his guest rapidly through the night, bringing Tom safely back home.
It was several days after this, during which time Tom and Ned had had many talks about the proposed trip. They had figured on what sort of a craft to use in the journey. Tom had about decided on a small, but very powerful, dirigible balloon, that could be packed in a small compass and taken along.
"This city may be in some mountain valley, and a balloon will be the only way we can get to it," he told Ned.
"That's right," agreed his chum. "By the way, you haven't heard any more about Andy; have you?"
"Not a thing. Haven't even seen him. None of us have."
"There goes Rad, I wonder if he's seen him."
"No, or he'd have mentioned it to me. Hey, Rad," Tom called to the colored man, what are you going to do?"
"Whitewash de back fence, Massa Tom. It's in a mos' disrupted state ob disgrace. I'se jest natchally got t' whitewash it."
"All right, Rad, and when you get through come back here. I've got another job for you."
