With the approach of evening all is changed. A mountain will suddenly intercept the sun; a shadow fall upon the valley; in ten minutes the thermometer will drop as many degrees; the peaks that are no longer shone upon dwindle into ghosts; and meanwhile, overhead, if the weather be rightly characteristic of the place, the sky fades towards night through a surprising key of colours. The latest gold leaps from the last mountain. Soon, perhaps, the moon shall rise, and in her gentler light the valley shall be mellowed and misted, and here and there a wisp of silver cloud upon a hilltop, and here and there a warmly glowing window in a house, between fire and starlight, kind and homely in the fields of snow. But the valley is not seated so high among the clouds to be eternally exempt from changes. The clouds gather, black as ink; the wind bursts rudely in; day after day the mists drive overhead, the snowflakes flutter down in blinding disarray; daily the mail comes in later from the top of the pass; people peer through their windows and foresee no end but an entire seclusion from Europe, and death by gradual dry-rot, each in his indifferent inn; and when at last the storm goes and the sun comes again, behold a world of unpolluted snow, glossy like fur, bright like daylight, a joy to wallowing dogs and cheerful to the souls of men. Or perhaps from across storied and malarious Italy, a wind cunningly winds about the mountains and breaks, warm and unclean, upon our mountain valley. Every nerve is set ajar; the conscience recognises, at a gust, a load of sins and negligences hitherto unknown; and the whole invalid world huddles into its private chambers, and silently recognises the empire of the Foehn.
