“‘Why, in order that the countings may not get mixed, of course; it is necessary that when he has paid for one idol he should carry it to a place aside, and then return and pay for the second, carrying it to the first, and in such a manner to the end. In this way the sun sinks behind the mountains.’ “‘But,’ said Yung, his voice thick with his great discovery, ‘if he could pay for the entire quantity at once, then it would take but a hundredth part of the time, and so more idols could be sold.’ “‘How could this be done?’ inquired Ning wonderingly. ‘Surely it is impossible to conjecture the value of so many idols.’ “‘To the unlearned it would indeed be impossible,’ replied Yung proudly, ‘but by the aid of my literary researches I have been enabled to discover a process by which such results would be not a matter of conjecture, but of certainty. These figures I have committed to tablets, which I am prepared to give to your mercenary and slow-witted father in return for your incomparable hand, a share of the profits, and the dismissal of the uninventive and morally threadbare Li Ting.’ “‘When the earth-worm boasts of his elegant wings, the eagle can afford to be silent,’ said a harsh voice behind them; and turning hastily they beheld Li Ting, who had come upon them unawares. ‘Oh, most insignificant of table-spoilers,’ he continued, ‘it is very evident that much over-study has softened your usually well-educated brains. Were it not that you are obviously mentally afflicted, I should unhesitatingly persuade my beautiful and refined sword to introduce you to the spirits of your ignoble ancestors. As it is, I will merely cut off your nose and your left ear, so that people may not say that the Dragon of the Earth sleeps and wickedness goes unpunished.’ “Both had already drawn their swords, and very soon the blows were so hard and swift that, in the dusk of the evening, it seemed as though the air were filled with innumerable and many-coloured fireworks. Each was a practised swordsman, and there was no advantage gained on either side, when Ning, who had fled on the appearance of Li Ting, reappeared, urging on her father, whose usually leisurely footsteps were quickened by the dread that the duel must surely result in certain loss to himself, either of a valuable servant, or of the discovery which Ning had briefly explained to him, and of which he at once saw the value.
