alone in future."

Quinn seemed to enjoy these propositions, and it was apparent at a glance that he had no intention of accepting twenty thousand dollars and renouncing his discoveries.

"Gentlemen," said he, "you are already half convinced that I am no dreamer, for you are financiers, and, while twenty thousand dollars is no more to you than twenty cents is to me, it is not your habit to give your money away. I repeat that you are inclined to have faith in me, and before many minutes I shall have made your belief in my abilities complete."

"Am I to understand that you decline our offer?" demanded Popham.

"Most decidedly!"

"Then there is nothing more to be said. Come on, gentlemen," and Popham started toward the door.

"A moment more, if you please," requested the professor.

"Not another second!" cried Popham. "Our offer is withdrawn; and, if your so-called discoveries amount to anything, we shall find other means for making them ineffective."

I had been interested in proceedings to an extent that had all but caused me to forget my purpose. The plutocrats were about to leave the castle in a temper, and if I wrested tribute from them it must be now or never.

Starting up, I drew my revolver and ran hastily down the iron stairs.
