"No, by God! but I'll add another five and make it an even twenty thousand!"

"May I suggest you double instead, and make it thirty?" inquired
Barnabas.

"Ha!—may I venture to ask how much higher you are prepared to go?"

"Why, sir," said Barnabas thoughtfully, "I have some odd six hundred thousand pounds, and I am prepared to risk—a half."

"Vastly fine, sir!" laughed Sir Mortimer, "why not put it at a round million and have done with it. No, egad! I want something more than your word—"

"You might inquire of my bankers," Barnabas suggested.

"Twenty thousand will suit me very well, sir!" nodded Sir Mortimer.

"Then you take me at that figure, Sir Mortimer?"

"Yes, I bet you twenty thousand guineas that you do not pass the winning-post ahead of me! And what's more,—non-starters to forfeit their money! Oh, egad,—I'll take you!"
