In frosty weather, again, when the houses take hard, stern tints, when the sky is clear over great part of its extent, but with heavy thunderous-looking clouds in places--clouds full of snow--the sun becomes of a red or orange hue, and reminds one of the lines of Longfellow when Othere reached the North Cape-- "Round in a fiery ring Went the great sun, oh King! With red and lurid light." The redness of the winter sun in London is, indeed, characteristic. A sunset in winter or early spring floods the streets with fiery glow. It comes, for instance, down Piccadilly; it is reflected from the smooth varnished roofs of the endless carriages that roll to and fro like the flicker of a mighty fire; it streaks the side of the street with rosiness. The faces of those who are passing are lit up by it, all unconscious as they are. The sky above London, indeed, is as full of interest as above the hills. Lunar rainbows occasionally occur; two to my knowledge were seen in the direction and apparently over the metropolis recently. When a few minutes on the rail has carried you outside the hub as it were of London, among the quiet tree-skirted villas, the night reigns as completely as in the solitudes of the country. Perhaps even more so, for the solitude is somehow more apparent. The last theatre-goer has disappeared inside his hall door, the last dull roll of the brougham, with its happy laughing load, has died away--there is not so much as a single footfall. The cropped holly hedges, the leafless birches, the limes and acacias are still and distinct in the moonlight. A few steps farther out on the highway the copse or plantation sleeps in utter silence. But the tall elms are the most striking; the length of the branches and their height above brings them across the light, so that they stand out even more shapely than when in leaf. The blue sky (not, of course, the blue of day), the white moonlight, the bright stars--larger at midnight and brilliant, in despite of the moon, which cannot overpower them in winter as she does in summer evenings--all are as beautiful as on the distant hills of old. By night, at least, even here, in the still silence, Heaven has her own way. When the oak leaves first begin to turn buff, and the first acorns drop, the redwings arrive, and their "kuk-kuk" sound in the hedges and the shrubberies in the gardens of suburban villas. They seem to come very early to the neighbourhood of London, and before the time of their appearance in other districts. The note is heard before they are seen; the foliage of the shrubberies, still thick, though changing colour, concealing them. Presently, when the trees are bare, with the exception of a few oaks, they have disappeared, passing on towards the west. The fieldfares, too, as I have previously observed, do not stay. But missel-thrushes seem more numerous near town than in the country.
