The dispatches which this courier bore must have been of immense importance. Michael Strogoff knew, therefore, that every effort would be made to capture him.

But what he did not know, and could not know, was that Marfa Strogoff was in the hands of Ivan Ogareff, and that she was about to atone, perhaps with her life, for that natural exhibition of her feelings which she had been unable to restrain when she suddenly found herself in the presence of her son. And it was fortunate that he was ignorant of it. Could he have withstood this fresh trial?

Michael Strogoff urged on his horse, imbuing him with all his own feverish impatience, requiring of him one thing only, namely, to bear him rapidly to the next posting-house, where he could be exchanged for a quicker conveyance.

At midnight he had cleared fifty miles, and halted at the station of Koulikovo. But there, as he had feared, he found neither horses nor carriages. Several Tartar detachments had passed along the highway of the steppe. Everything had been stolen or requisitioned both in the villages and in the posting-houses. It was with difficulty that Michael Strogoff was even able to obtain some refreshment for his horse and himself.

It was of great importance, therefore, to spare his horse, for he could not tell when or how he might be able to replace it. Desiring, however, to put the greatest possible distance between himself and the horsemen who had no doubt been dispatched in pursuit, he resolved to push on. After one hour's rest he resumed his course across the steppe.

Hitherto the weather had been propitious for his journey. The temperature was endurable. The nights at this time of the year are very short, and as they are lighted by the moon, the route over the steppe is practicable. Michael Strogoff, moreover, was a man certain of his road and devoid of doubt or hesitation, and in spite of the melancholy thoughts which possessed him he had preserved his clearness of mind, and made for his destined point as though it were visible upon the horizon. When he did halt for a moment at some turn in the road it was to breathe his horse. Now he would dismount to ease his steed for a moment, and again he would place his ear to the ground to listen for the sound of galloping horses upon the steppe. Nothing arousing his suspicions, he resumed his way.

On the 30th of July, at nine o'clock in the morning, Michael Strogoff passed through the station of Touroumoff and entered the swampy district of the Baraba.

There, for a distance of three hundred versts, the natural obstacles would be extremely great. He knew this, but he also knew that he would certainly surmount them.

These vast marshes of the Baraba, form the reservoir to all the rain-water which finds no outlet either towards the Obi or towards the Irtych. The soil of this vast depression is entirely argillaceous, and therefore impermeable, so that the waters remain there and make of it a region very difficult to cross during the hot season. There, however, lies the way to Irkutsk, and it is in the midst of ponds, pools, lakes, and swamps, from which the sun draws poisonous exhalations, that the road winds, and entails upon the traveler the greatest fatigue and danger.

Michael Strogoff spurred his horse into the midst of a grassy prairie, differing greatly from the close-cropped sod of the steppe, where feed the immense Siberian herds. The grass here was five or six feet in height, and had made room for swamp-plants, to which the dampness of the place, assisted by the heat of summer, had given giant proportions. These were principally canes and rushes, which formed a tangled network, an impenetrable undergrowth, sprinkled everywhere with a thousand flowers remarkable for the brightness of their color.

Michael Strogoff, galloping amongst this undergrowth of cane, was no longer visible from the swamps which bordered the road. The tall grass rose above him, and his track was indicated only by the flight of innumerable aquatic birds, which rose from the side of the road and dispersed into the air in screaming flocks.
