A moving panorama was displayed on both sides of the river, and, by an optical illusion, it appeared as if it was the raft which was motionless before a succession of picturesque scenes. Here were high granite cliffs, there wild gorges, down which rushed a torrent; sometimes appeared a clearing with a still smoking village, then thick pine forests blazing. But though the Tartars had left their traces on all sides, they themselves were not to be seen as yet, for they were more especially massed at the approaches to Irkutsk.

All this time the pilgrims were repeating their prayers aloud, and the old boatman, shoving away the blocks of ice which pressed too near them, imperturbably steered the raft in the middle of the rapid current of the Angara.

CHAPTER XI BETWEEN TWO BANKS

BY eight in the evening, the country, as the state of the sky had foretold, was enveloped in complete darkness. The moon being new had not yet risen. From the middle of the river the banks were invisible. The cliffs were confounded with the heavy, low-hanging clouds. At intervals a puff of wind came from the east, but it soon died away in the narrow valley of the Angara.

The darkness could not fail to favor in a considerable degree the plans of the fugitives. Indeed, although the Tartar outposts must have been drawn up on both banks, the raft had a good chance of passing unperceived. It was not likely either that the besiegers would have barred the river above Irkutsk, since they knew that the Russians could not expect any help from the south of the province. Besides this, before long Nature would herself establish a barrier, by cementing with frost the blocks of ice accumulated between the two banks.

Perfect silence now reigned on board the raft. The voices of the pilgrims were no longer heard. They still prayed, but their prayer was but a murmur, which could not reach as far as either bank. The fugitives lay flat on the platform, so that the raft was scarcely above the level of the water. The old boatman crouched down forward among his men, solely occupied in keeping off the ice blocks, a maneuver which was performed without noise.

The drifting of the ice was a favorable circumstance so long as it did not offer an insurmountable obstacle to the passage of the raft. If that object had been alone on the water, it would have run a risk of being seen, even in the darkness, but, as it was, it was confounded with these moving masses, of all shapes and sizes, and the tumult caused by the crashing of the blocks against each other concealed likewise any suspicious noises.

There was a sharp frost. The fugitives suffered cruelly, having no other shelter than a few branches of birch. They cowered down together, endeavoring to keep each other warm, the temperature being now ten degrees below freezing point. The wind, though slight, having passed over the snow-clad mountains of the east, pierced them through and through.

Michael and Nadia, lying in the afterpart of the raft, bore this increase of suffering without complaint. Jolivet and Blount, placed near them, stood these first assaults of the Siberian winter as well as they could. No one now spoke, even in a low voice. Their situation entirely absorbed them. At any moment an incident might occur, which they could not escape unscathed.

For a man who hoped soon to accomplish his mission, Michael was singularly calm. Even in the gravest conjunctures, his energy had never abandoned him. He already saw the moment when he would be at last allowed to think of his mother, of Nadia, of himself! He now only dreaded one final unhappy chance; this was, that the raft might be completely barred by ice before reaching Irkutsk. He thought but of this, determined beforehand, if necessary, to attempt some bold stroke.

Restored by a few hours' rest, Nadia had regained the physical energy which misery had sometimes overcome, although without ever having shaken her moral energy. She thought, too, that if Michael had to make any fresh effort to attain his end, she must be there to guide him. But in proportion as she drew nearer to Irkutsk, the image of her father rose more and more clearly before her mind.
