For some time they could not use their boat. They were obliged to drag it through a tangled mass of roots and vines and treacherous brake, until they could reach the stream. The exertion they made was almost super-human, and would have been impossible to them except under the terrible incentive that drew them on. Only when they were afloat, and paddling warily along the dubious and unfamiliar current, did they understand how their labor had sapped their strength. And only then, also, did they perceive that they had passed from a world of uproar and elemental upheaving into a realm as secluded and quiet as a tomb.
The mighty winds, it is true, rumbled through the tops of the trees under which they were buried; but the dense mass of boughs and springing verdure that walled in the secret places of the swamp, as with a hundred separate walls, would not permit that wild commotion of the outer air to reach them. Birds had fled hither from the hurricane, and even dared to chirp in the lonely and forsaken thickets of this uncouth wilderness. Day was spreading above the thick canopy of boughs, and was pouring its light all round the vast area of the swamp at its edges; but here, within, there reigned a perpetual and awful twilight. The slow, brown stream ran on ahead, turning here and there, opening into blind creeks, sprawling through the dusk like some great snaky thing with a hundred sinuous arms and feelers; but it was rather by instinct and touch than by any other means that the two men in the canoe traced the main body of the slimy current. No landmarks were to be counted on there: the points of the compass were obliterated.
The swamp was the home of oblivion. They moved through it as through a place set apart for those who are condemned to a death in life.
From time to time they shouted aloud. Having no weapons with them, they could make no other signal. They called to Sylv, with a hope that he might answer to them from the next bend in the stream, or from some adjoining depth of bough and bramble. Yet always the same dead silence swallowed up the sound of their voices, and no human response came back. The raw air, the shade, the moisture of the oozing current, gradually invaded them with a chill that seemed to run through their very bones; but it was with a more deadly chill that they gazed into one another's eyes, and thought, without saying it, that perhaps they were even then pushing their way over the liquid grave in which Sylv might have sought relief.
