But since the Muscovite Government had believed these hordes reduced to absolute submission, they had been abandoned, and now could not be used; just at the time when they were needed. Many of these forts had been reduced to ashes; and the boatmen even pointed out the smoke to Michael, rising in the southern horizon, and showing the approach of the Tartar advance-guard.

As soon as the ferryboat landed the tarantass on the right bank of the Ichim, the journey across the steppe was resumed with all speed. Michael Strogoff remained very silent. He was, however, always attentive to Nadia, helping her to bear the fatigue of this long journey without break or rest; but the girl never complained. She longed to give wings to the horses. Something told her that her companion was even more anxious than herself to reach Irkutsk; and how many versts were still between!

It also occurred to her that if Omsk was entered by the Tartars, Michael's mother, who lived there, would be in danger, and that this was sufficient to explain her son's impatience to get to her.

Nadia at last spoke to him of old Marfa, and of how unprotected she would be in the midst of all these events.

"Have you received any news of your mother since the beginning of the invasion?" she asked.

"None, Nadia. The last letter my mother wrote to me contained good news. Marfa is a brave and energetic Siberian woman. Notwithstanding her age, she has preserved all her moral strength. She knows how to suffer."

"I shall see her, brother," said Nadia quickly. "Since you give me the name of sister, I am Marfa's daughter."

And as Michael did not answer she added:

"Perhaps your mother has been able to leave Omsk?"

"It is possible, Nadia," replied Michael; "and I hope she may have reached Tobolsk. Marfa hates the Tartars. She knows the steppe, and would have no fear in just taking her staff and going down the banks of the Irtych. There is not a spot in all the province unknown to her. Many times has she traveled all over the country with my father; and many times I myself, when a mere child, have accompanied them across the Siberian desert. Yes, Nadia, I trust that my mother has left Omsk."

"And when shall you see her?"

"I shall see her--on my return."

"If, however, your mother is still at Omsk, you will be able to spare an hour to go to her?"

"I shall not go and see her."

"You will not see her?"

"No, Nadia," said Michael, his chest heaving as he felt he could not go on replying to the girl's questions.

"You say no! Why, brother, if your mother is still at Omsk, for what reason could you refuse to see her?"

"For what reason, Nadia? You ask me for what reason," exclaimed Michael, in so changed a voice that the young girl started. "For the same reason as that which made me patient even to cowardice with the villain who--" He could not finish his sentence.

"Calm yourself, brother," said Nadia in a gentle voice. "I only know one thing, or rather I do not know it, I feel it. It is that all your conduct is now directed by the sentiment of a duty more sacred--if there can be one--than that which unites the son to the mother."

Nadia was silent, and from that moment avoided every subject which in any way touched on Michael's peculiar situation. He had a secret motive which she must respect. She respected it.

The next day, July 25th, at three o'clock in the morning, the tarantass arrived at Tioukalmsk, having accomplished a distance of eighty miles since it had crossed the Ichim. They rapidly changed horses. Here, however, for the first time, the iemschik made difficulties about starting, declaring that detachments of Tartars were roving across the steppe, and that travelers, horses, and carriages would be a fine prize for them.

Only by dint of a large bribe could Michael get over the unwillingness of the iemschik, for in this instance, as in many others, he did not wish to show his podorojna. The last ukase, having been transmitted by telegraph, was known in the Siberian provinces; and a Russian specially exempted from obeying these words would certainly have drawn public attention to himself--a thing above all to be avoided by the Czar's courier. As to the iemschik's hesitation, either the rascal traded on the traveler's impatience or he really had good reason to fear.
