"These Russians have evidently a higher respect for their doctors than have the Swedes," he said to himself. "I am sure that not even the chief surgeon of the army would be treated with anything like the same respect, and, indeed, no one would recognize him at all, if he were not in uniform."

The doctor seemed to pay no attention to what was passing round him, but was muttering angrily to himself. It was not until they dashed out into the open country that he seemed to remember Charlie's presence at his side.

"These people are enough to vex one of the saints, by their stupidity," he said. "Unless they have some one standing behind them with a whip, they cannot be trusted to do what they are told. It is not that they are not willing, but that they are stupid. No one would believe that people could be so stupid. They drive me well nigh to madness sometimes, and it is the more irritating because, against stupidity, one is powerless. Beating a man or knocking him down may do him good if he is obstinate, or if he is careless, but when he is simply stupid it only makes him more stupid than before. You might as well batter a stone wall.

"You slept well and breakfasted well, Captain Carstairs?"

"Excellently well, thank you. What superb horses you have, doctor."

"Yes. I like travelling fast. Life is too short to throw away time in travelling. A busy man should always keep good horses."

"If he can afford to do so," Charlie said with a laugh. "I should say that every one, busy or not, would like to sit behind such horses as these, and, as you say, it would save a good deal of time to one who travelled much. But three such horses as these would only be in the reach of one with a very long purse."

"They were bred here. Their sire was one of three given by the king of England to the czar. The dams were from the imperial stables at Vienna. So they ought to be good."

Charlie guessed that the team must have been a present from the czar, and, remembering what Doctor Kelly had said of the czar's personal communications with him, he thought that the ruler of Russia must have a particular liking for doctors, and that the medical profession must be a more honoured and profitable one in Russia than elsewhere.

After driving with great rapidity for upwards of an hour along the banks of the Neva, Charlie saw a great number of people at work on an island in the middle of the river, some distance ahead, and soon afterwards, to his surprise, observed a multitude on the flat, low ground ahead.
