A mountain valley has, at the best, a certain prison-like effect on the imagination, but a mountain valley, an Alpine winter, and an invalid's weakness make up among them a prison of the most effective kind. The roads indeed are cleared, and at least one footpath dodging up the hill; but to these the health-seeker is rigidly confined. There are for him no cross-cuts over the field, no following of streams, no unguided rambles in the wood. His walks are cut and dry. In five or six different directions he can push as far, and no farther, than his strength permits; never deviating from the line laid down for him and beholding at each repetition the same field of wood and snow from the same corner of the road. This, of itself, would be a little trying to the patience in the course of months; but to this is added, by the heaped mantle of the snow, an almost utter absence of detail and an almost unbroken identity of colour. Snow, it is true, is not merely white. The sun touches it with roseate and golden lights. Its own crushed infinity of crystals, its own richness of tiny sculpture, fills it, when regarded near at hand, with wonderful depths of coloured shadow, and, though wintrily transformed, it is still water, and has watery tones of blue. But, when all is said, these fields of white and blots of crude black forest are but a trite and staring substitute for the infinite variety and pleasantness of the earth's face. Even a boulder, whose front is too precipitous to have retained the snow, seems, if you come upon it in your walk, a perfect gem of colour, reminds you almost painfully of other places, and brings into your head the delights of more Arcadian days--the path across the meadow, the hazel dell, the lilies on the stream, and the scents, the colours, and the whisper of the woods. And scents here are as rare as colours. Unless you get a gust of kitchen in passing some hotel, you shall smell nothing all day long but the faint and choking odour of frost. Sounds, too, are absent: not a bird pipes, not a bough waves, in the dead, windless atmosphere. If a sleigh goes by, the sleigh-bells ring, and that is all; you work all winter through to no other accompaniment but the crunching of your steps upon the frozen snow.
