The road was fair enough for stout walkers, and the air grew lighter and easier to breathe as the two ascended. But the settled gloom remained as it had remained for days back. Nature seemed to have come to a pause. The sense of hearing, no less than the sense of sight, was troubled by having to wait so long for the change, whatever it might be, that impended. The silence was as palpable and heavy as the lowering clouds--or rather cloud, for there seemed to be but one in all the sky, and that one covering the whole of it.
Although the light was thus dismally shrouded, the prospect was not obscured. Down in the valley of the Rhone behind them, the stream could be traced through all its many windings, oppressively sombre and solemn in its one leaden hue, a colourless waste. Far and high above them, glaciers and suspended avalanches overhung the spots where they must pass, by-and-by; deep and dark below them on their right, were awful precipice and roaring torrent; tremendous mountains arose in every vista. The gigantic landscape, uncheered by a touch of changing light or a solitary ray of sun, was yet terribly distinct in its ferocity. The hearts of two lonely men might shrink a little, if they had to win their way for miles and hours among a legion of silent and motionless men--mere men like themselves--all looking at them with fixed and frowning front. But how much more, when the legion is of Nature's mightiest works, and the frown may turn to fury in an instant!
