They were already beneath the huge gateway, and glancing upward David was able to distinguish the roof, which was blackened with the smoke of ages, for in the cold months the guards were accustomed to place braziers on the roadway so as to make watching possible. A second later, however, the swaying lantern disappeared, the man who carried it diving out of sight into a gallery leading from the gateway. On went the party, Jong leading the ponies, while David had taken the rein of the animal drawing the cart. He heard the wicker of the baskets creaking, and guessed that his prisoners were struggling with might and main. But there seemed no one near enough to hear the noise, while the strong native cart did not feel the movement of the ruffians it carried. Just at the very exit from the gates there stood one solitary sentry, and he, as if bearing in mind the caution which Jong had given his fellow, turned his face away. It was not well, perhaps, he thought, to look too closely upon the doings of such a high personage as the deputy-governor.

'Else it might happen that I should be called in evidence,' he told himself, 'when, had I, indeed, seen his honour, it would be hard to find a reason for denying the fact. A deputy-governor is a mighty person. He may come and go as he likes.'

After all, the incident in such a country as China, where conspiracy is common enough, was not so very remarkable. 'Saving face' is an expression thoroughly well known, and many and many an exalted person has been under the need of cloaking his movements, so that when an accusation of complicity in some conspiracy was levelled at him, he could bring evidence to prove that he had never been seen in that locality, and that, on the contrary, he was at home with his servants. And, no doubt, here was some similar movement. His Excellency was, without fear of contradiction, asleep in his palace. His servants could swear that on the morrow. It was not the business of the guard at the gate to inspect too closely, when he had received a direct message ordering him to pass the governor secretly. Besides, there were the foreign-devils, of whom the rumour had reached him that they had been attacked. Doubtless the baskets he heard creaking in the cart held them securely, though for his part, the guard was not going to be too curious.

'Pass! All's well,' he whispered, as the cart issued from the gate and crossed the drawbridge, with Dick in close attendance. 'Pass to your business.'

The revolving gate scrunched on its runners. The huge hinges creaked. The mass of wood, with its heavy bronze bolts and locks, swung into position with a bang. Then the dull reverberation beneath the drawbridge died away, while the wheels of the cart began to rattle on the hard roadway. David wiped the perspiration from his forehead, while Dick let go a gentle whistle. But not one dared to alter his position. There might be, and probably were, many pairs of eyes watching them from the narrow slits on the outer face of the towers and bastions, the slits from which, even now-a-days, should there be a siege, Chinese soldiers would discharge arrows, using precisely the same weapons as did their forefathers, and that in spite of the fact that many of their comrades were armed with modern rifles. Yes, no doubt, many an inquisitive glance was cast after the party, and it was still necessary to preserve caution. And so they continued, showing black and easily distinguishable on the white roadway, till the latter curled out of sight of the city in a stretch of forest. It was only then that David dared to bring the animal hauling the cart to an abrupt halt, while a whistle caused Jong to draw rein promptly.

'I think,' began Dick, struggling to keep his impassiveness, and yet almost bursting in consequence, 'I think things begin to look a little more healthy. A fellow begins to actually believe that he may be wanting another breakfast. In fact, one may go so far as to say that it's a case of all right.'

Then he went off into a fit of the most hilarious laughter, which doubled him up, till he looked anything but the noble Governor of the city they had just quitted.

'What a tale for the Professor!' he shouted. 'Won't he enjoy the whole thing, and roar when he hears how you've turned the tables.'

'I! We, you mean,' came sharply from David, who was enjoying his friend's remarks immensely. 'We, you should have said.'

'You're wrong. I said you, and I meant you. It's you all the time. There's no one else in it,' declared Dick warmly.
