'There's not a doubt that we have come to China at a most unfortunate time,' the Professor had declared. 'If I had heard of the plague in this district before we sailed, I should have delayed my departure. But it is always the same with severe epidemics. There is a case here, and another there at first; then, suddenly, the disease blazes out in all directions, spreads like wild-fire, and creates pandemonium and terror everywhere. China is a country less prepared for such an event almost than any other, for the people are so intensely ignorant. You see they think to escape by rushing away from the infected areas, forgetting that in every case they carry the infection with them.'
'There was news from a place forty miles to the east that a band had taken up its quarters in a town of small proportions, and were terrorising the inhabitants,' David reminded himself. 'Tell me,' he asked of the headman, who had now almost recovered his breath, 'what is there to fear from these fellows? A thousand strong you place them?'
'There is that number at least, Excellency. As to their intentions, I tell you they will eat up all before them. Already they have emptied every sack and bin in our village. That was two nights ago, or almost so. By now they are starving once more, and will seize the first provisions which come their way. They will know at once that men have been camping here. They will investigate, and will gather the fact that it is a European expedition, and therefore rich. That will be enough for this army of frightened people, for though the thought of plague terrifies them, they fear nothing else. Hunger makes them terribly savage. They will murder us all if we do nothing to prevent them.'
'If that's the case I shall certainly object, and pretty strongly,' said David, with a decision which seemed to put heart into the headman. 'Bring your men along. We will see at once what can be done.'
They found on their return to the entrance of the stairway that the Professor and his helpers had been wonderfully busy. Every article of value had been carried down from the surface, while even the ponies had been transported bodily and placed in a position of safety.
'We've done all that's possible, I imagine,' said the leader. 'Now we have only to wait and see what happens. I trust these people will pass without giving us a call. Perhaps they will miss us altogether.'
'I hardly think so,' ventured David. 'The headman tells me that they are wonderfully well informed, and that they have come round this way so as to avoid soldiers sent to arrest their progress, and who are situated at this moment about forty miles to the east. Wouldn't it be as well to send a message across to their commanding officer?'
The Professor jumped at the suggestion. He hastily scrawled a message in Chinese, explaining the situation, and then, having caused two of the ponies to be carried to the surface again, he despatched one of the soldiers with the note.
'Ride fast,' he ordered. 'If these men attack us we shall have need of all the help that can be sent.'
No one who caught a glimpse of the fleeing army from Manchuria could doubt that statement, for a more tattered and desperate set David had never set his eyes on. They reached the excavation works in a straggling mass of hollow-eyed people, many of whom were almost too weak to drag one foot after the other. But there were strong men amongst them, in spite of their sunken cheeks, men whose blazing eyes and hungry looks showed that nothing but superior force would prevent their carrying out whatever they aimed at. Nor did they leave the Professor and his party long in doubt as to their intentions. A couple of ragged but huge men came down the stairway, their pigtails swaying from side to side, and called hoarsely to any one who might be in hearing. The Professor at once showed himself at the door of the apartment which he and his friends were occupying.
