"A plausible explanation, but I'm not sure it's good," Wyndham replied with a smile. "The head of our house was often extravagant but never, I think, a miser. We're not a greedy lot."

"You were traders; the object of trading is to get rich."

"I doubt if this was my uncle's, or some of my other ancestors' object, I think they valued money for what it would buy. Anyhow, they seldom kept it long."

"Since most of us value money for what it will buy, I don't understand," Marston rejoined.

"You bought a country house, a sober sportsman's life, and the liking of honest friends. Well, your investments were sound, but there are men of other temperaments they mightn't satisfy. I don't think they would have satisfied Rupert Wyndham."

"Then what did he expect to get in the swamps?"

"I don't know," said Wyndham, with a curious smile. "Perhaps strange experiences; perhaps knowledge and power. I imagine he knew he must buy them and was willing to pay."

"Power over tattooed bushmen!" Marston exclaimed. "What could they teach him?"

"Things we have begun to experiment with and their Ju-Ju men knew long since. The white man who knows the meaning of their tattoo marks has gone some distance; they're not all tribal signs. However, I don't know what Rupert Wyndham learned and it looks as if I shall not find out. Our object's very matter of fact; to earn as much money as possible."

"That is so. I mean to stick to it," said Marston firmly.
