“Well, as I would only be in the minority, I suppose I may as well vote in the affirmative,” said Mr. Chadwick.

“I’m only an outsider,” piped Dick, “and as I’ve got no business here anyhow, I don’t suppose you’ll take me. But I say, yes; because if we do get this Mega-what-you-may-call-um and the professor lets me take pictures and write a story, it’ll be the biggest newspaper stunt pulled off for a long time.”

“You’re appointed special correspondent of the expedition, then,” laughed Jack.

“I don’t know how to dank you,” declared the professor fervently. “You haf done a service to science dot cannot be paidt in money, even if ve don’t get der Megatherium. Budt now ve gedt down to business. If vee gedt der Megatherium or proof dot he exists, I agree to pay you fifteen thousand dollars for der use of der Vundership. If ve don’t gedt him, I pay you half dot sum undt five tousandt additional for your services. Does dot suit you?”

“Suits me,” said Jack, almost at once, after a glance had passed between himself and Tom.

“Very vell, den. Dot is arranged mitout fuss or fedders. I gif you an agreement.”

“Oh, that’s all right,” said the elder of the two owners of the Wondership, but the professor tore out of his pocket-book a leaf of paper and with his fountain pen rapidly scribbled and signed a contract.

“If I die, der people for whom I am doing dis vurk vill see dot you gedt der sum agreed upon,” he said, as he handed the paper to Jack, who took it under protest.

The preparations for the trip into the unknown regions to the west of them occupied most of the rest of that day. It was decided to leave Judkins in the camp with a supply of provisions, as no more weight than was necessary was wanted in the air craft,—for that they would have to make much of their voyage by the “air route” there was no question. The engineer appeared quite agreeable to this plan and apprehended no danger. In a week at the outside they were to fly back and see how he was faring.

They decided to make the start the next morning, which would bring them into the region the professor wished to reach about daybreak of the day following. This would give them an opportunity to scour the country and fix a permanent camp.
