Perhaps certain natural phenomena are most to be feared at that time, such as long-continuing and dense fogs, excessive cold, fearfully heavy snow-storms, which sometimes envelop whole caravans and cause their destruction. Hungry wolves also roam over the plain in thousands. But it would have been better for Michael Strogoff to face these risks; for during the winter the Tartar invaders would have been stationed in the towns, any movement of their troops would have been impracticable, and he could consequently have more easily performed his journey. But it was not in his power to choose either weather or time. Whatever the circumstances, he must accept them and set out.

Such were the difficulties which Michael Strogoff boldly confronted and prepared to encounter.

In the first place, he must not travel as a courier of the Czar usually would. No one must even suspect what he really was. Spies swarm in a rebellious country; let him be recognized, and his mission would be in danger. Also, while supplying him with a large sum of money, which was sufficient for his journey, and would facilitate it in some measure, General Kissoff had not given him any document notifying that he was on the Emperor's service, which is the Sesame par excellence. He contented himself with furnishing him with a "podorojna."
