In regard to movement, the scenery of the streets has no likeness to anything in nature. Clouds wing one way, streams flow, trees toss, thrill, and remain, but the crowd moves all ways without ever changing its spots, its dull violence of colour and contrast. Summer and day make the streets impossible for the painter. But the summer of London is most local and characteristic--not only in the west, when the scent of mignonette and the recurrent click of the bearing-rein and bit where carriages stand waiting are the very signs of town; summer at the Bank, summer that gives to the walls of Lombard Street a faint hint of reflected light, and fills at a glance ten thousand serried windows with the images of the sun. If there is everywhere a lack of spirit and sweetness, it is only that sunshine, with every tree and every flower, is converted to London and turns a Londoner. But such charm as there may still be in the touches of the sun are perceptible rather in the few streets that keep their ancient narrowness. Here there is precisely the possibility of that inter-reflection of sunshine and warm light, from house to facing house, which in its gentle splendour is the chief loveliness of summer in southern cities, where walls are here and there blank, and tenderly coloured. Reflected light is the beauty of shadows, and really one may see a shadow faintly so transformed in the course of the delicate curves of City streets. Such curves are not in the wider streets; they are beautiful, apart from the chances and changes of light which they foster, and many a narrow street leading to the right and to the left out of Cheapside, or some other of the central London ways, takes curves as subtle as those of a swimming fish's tail. Otherwise London curves are distressingly ugly and dreary--those of a crescent, for example. But as much as the crescent offends, the light wave of a fish's-tail street pleases the eye, with its fine deflections. A wave of this kind is frequent enough in villages, but a certain height in the houses gives it all its character in London.
