THE distance between Moscow and Irkutsk, about to be traversed by Michael Strogoff, was three thousand four hundred miles. Before the telegraph wire extended from the Ural Mountains to the eastern frontier of Siberia, the dispatch service was performed by couriers, those who traveled the most rapidly taking eighteen days to get from Moscow to Irkutsk. But this was the exception, and the journey through Asiatic Russia usually occupied from four to five weeks, even though every available means of transport was placed at the disposal of the Czar’s messengers. Michael Strogoff was a man who feared neither frost nor snow. He would have preferred traveling during the severe winter season, in order that he might perform the whole distance by sleighs. At that period of the year the difficulties which all other means of locomotion present are greatly diminished, the wide steppes being leveled by snow, while there are no rivers to cross, but simply sheets of glass, over which the sleigh glides rapidly and easily. 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.” This podorojna was made out in the name of Nicholas Korpanoff, merchant, living at Irkutsk. It authorized Nicholas Korpanoff to be accompanied by one or more persons, and, moreover, it was, by special notification, made available in the event of the Muscovite government forbidding natives of any other countries to leave Russia.
