He went off at a run down the moon-lit street, careless if he were observed, now that he had that important letter. David watched him depart, and then strolled back to the cell. He began to feel that the worst part of their troubles were over, as if safety lay before them. The lines left his forehead as he thought of the success which had already attended their efforts, while he smiled a meaning smile as he began to pull off his clothing.

'Strip yours,' he commanded Chang. 'Quick with it.'

'And am I to dress in those of the Tartar, Excellency?' asked the wretch.

'Just as you like. In any case I'm going to provide you with another covering. I don't fancy there'll be any chance of your getting cold.'

'But, Excellency——' whined the man.

'You be slippy and don't waste time talking,' cried Dick, beginning to fathom his chum's meaning. 'Going to provide him with another covering, eh?' he grinned. 'You don't mean that you're——'

'Because, you see,' added Dick, enjoying the discomfiture of the rascal immensely, 'you'll be carried—carried, Chang. Got it?'

It was evident that the wretch had, for he shivered and whined as he sat on the edge of the kang. But David took no more notice of him for the moment. He coolly dressed himself in the clothes this secret enemy had been wearing, and then walked out of the cell. A quarter of an hour later, when Jong arrived on the scene, and the scrunch of wheels was heard outside on the road, two men stood ready to accompany the party.

'Carry out the baskets,' whispered one, who seemed to be none other than the man who had come to warn the inhabitants of Hatsu of the foreign devils. 'You will give all orders till we are out of the city.'
