'But tell us why, your Excellency,' he asked, politely. 'What will prevent us, supposing you give your consent?'

'The plague may prevent your going,' came the answer. 'You have no idea of the nature or of the importance of this pest. Manchuria to-day is in the last stage of disorder. Thousands die every twenty-four hours, while there is no time and not enough men to conduct the burials. The victims are being burned. From Manchuria to Pekin is not such a far cry, while the neighbourhood of these ruins you seek is even closer to the infected area. You must understand me, I do not say that your own fear of contagion will hold you back. That is not the position at all. What I do suggest is that it may be prudent of your leader to remain in these parts, rather than go farther afield. For disaster does not come of its own accord in the eyes of my countrymen. You have seen for yourself how their thoughts run. The poor ignorant fellows believe that a pest is brought, is settled upon them by way of punishment, and should you and your friends be away in some savage part, all alone, you might very well be set upon as the cause of the disaster. In this city of Hatsu, thanks to the scheming of that rascal Chang, you were accused of this crime, and his ignorant tools snapped at the chance of killing you. In the neighbourhood of those Mongolian ruins the natives are, I fear, likely to be even more ignorant and stupid. However, we will see what can be done; I might be able to send an escort. And now I propose travelling farther with you. I myself shall visit the camp where your friends are situated, so that I may formally welcome them to my province.'

Imagine the Professor's astonishment at the return of David and Dick. He emerged from a deep excavation, which the coolies had been engaged in beneath the debris covering the ruined city wherein Tsin had dwelt once on a time, and advanced with something approaching consternation on his face.

'Returned already,' he cried. 'Why? And with an escort, and a mandarin too if my eyes don't cheat me. Not got into trouble, I do hope.'

'Heaps,' laughed Dick, enjoying the position. 'The exalted official following comes to greet you. He's already chopped off three heads while in our company.'

'It's Twang Chun himself, the governor of the province,' explained David, laughing at his chum's fun. 'We happened to meet him. The chopping off of heads is a long story. But his Excellency comes to welcome you to the province, and to discuss the question of your journey to the Mongolian city. He thinks there may be difficulties.'

'I trust not, indeed. This expedition of ours would be shorn of half its profit if we were unable to go to Chi-Seang, for, if report speaks true, there are relics to be discovered of the very greatest interest. But I will speak with his Excellency; bring him to the tent. I will get washed, and put on clean clothing.'

The meeting between the two gentlemen was most cordial, and as may well be imagined, every one belonging to the Professor's staff worked hard so as to prepare entertainment for his Excellency, since Twang Chun was, indeed, an exalted official, and as became one of his high rank and importance, travelled with an escort and retinue to match. In a very short space of time his camp had been pitched, when David had an opportunity of seeing how such things could be done in this country of the Dragon. A most gorgeous silken tent was erected, boasting of an inner lining of painted silk which made of the place a veritable palace. And in rear were placed tents for his retinue, less imposing perhaps, but grand in their magnificence when compared with those to be seen in this country.

'Him wonerful man,' lisped Jong, who was something of a hero now that he had returned to his comrades, and whose busy tongue was already wagging freely. Indeed, long before the Professor or Alphonse gathered the full details of David's exploit, and of Dick's assistance, all else within the camp were familiar with them. There was even violent movement amongst the stolid Chinese. Ho Hung leaped wildly into the air, and gave free vent to his enthusiasm, while the more placid Fing chuckled hugely. As for Jong himself, he vowed that he would never stop giggling, for the reversal of the fortunes of attackers and attacked was so amusing. It tickled the faithful Chinaman immensely, when he recollected how he and his masters had hoodwinked every one, and how they had conveyed the deputy-governor of Hatsu from the city and right under the noses of the soldiery. Next to David and Dick, perhaps the wise and strong Twang Chun claimed his admiration.

'Velly velly fine, Excellency,' he lisped again. 'Him knowee so velly well how to manage little tings like dat which happen to us. Him oh so nicee and gentle. Kuttee off de heads of de rascal nicee. Jong tink him fit almost to be de Empelor.'
