It is some little treason to a natural storm to admire too eagerly the mimic wrack and menace of the paltry tempest of the smoke. Only by acknowledging the climate of London to be more than half an artificial climate, and by treating our own handiwork--the sky of our manufacture--with a relative contempt, are we excused for thinking the effects in any sense beautiful. Let us avoid serious words of description. The whirls of floating smoke that darken the sunset are 'lurid' to no very grand purpose; and the threat from even twice as many kitchen fires never would be terrible. It is a tale signifying nothing. Let us grant that there is now and then an effect of handsome grime, but there is no system in this scenery of smoke. What form seems at times to declare itself is bestowed by the light. The sun rules from a centre, whatever the circumference be made of--mist from mountain heights or vapour from that series of successive fleeting solitudes, the ocean, or refuse from a million fireplaces; and from this reigning centre his rays seem to compel a kind of organism. There is no chance-medley where he rules, because of his long, distributed lights, and straight, infallible, divergent shadows that pick off the points and pinnacles of a thousand distances. The lowering sun will not permit the smoke to show so shapeless, so lifeless, so unbounded as it is; he takes his place in the middle of a wheel, and commands at any rate a mechanical order. Otherwise, and without a sun lowered into your picture, the smoke-mingled sky is the most unplanned in the world. It has no confederacy, and no direction. Nothing leads, and there are no figures, no troops, no companies; there is no history, nor approach. The smoke is helpless. It is perpetually subject to gravitation; no wind makes it buoyant, and no electric impetus lifts it against a wind. It constantly and drearily drops, as you may see if you look against any London horizon; the minute shower that it carries never ceases and never lifts, but sifts down momently from the low sky into which the chimneys raised it at first. That one upward spring was all its life. Thenceforth it does but drift until it is all shed, to the last black atom, upon the face of the town. And yet you may, twenty times a day in London, hear the smoke called cloud. Thunderstorms are announced as lurking in the heart of the powerless bosom of the smoke, and showers are threatened where there never was anything so fresh as a drop of rain. The puny darkness is supposed capable of lightnings, and out of the grime is expected the thunderbolt. The splendid name of the cloud is given to this poor local vesture of decay; no use or custom seems sufficient to make the London sky of mechanical suspension familiar to the citizen; when he faces it at the end of a brief distance he calls it by the names proper to the celestial heights, and he is hardly convinced of the truth when he sees it walk his streets.
