The fog tiptoes into the streets. It walks like a great cat through the air and slowly devours the city.

The office buildings vanish, leaving behind thin pencil lines and smoke blurs. The pavements become isolated, low-roofed corridors. Overhead the electric signs whisper enigmatically and the window lights dissolve.

The fog thickens till the city disappears. High up, where the mists thin into a dark, sulphurous glow, roof bubbles float. The great cat's work is done. It stands balancing itself on the heads of people and arches its back against the vanished buildings.

I walk along thinking about the way the streets look and arranging adjectives in my mind. In the heavy mist people appear detached. They no longer seem to belong to a pursuit in common. Usually the busy part of the city is like the exposed mechanism of some monstrous clock. And people scurry about losing themselves in cogs and springs and levers.

But now the monstrous clock is almost hidden. The stores and offices and factories that form the mechanism of this clock are buried behind the fog. The cat has eaten them up. Hidden within the mist the cogs still turn and the springs unwind. But for the moment they seem non-existent. And the people drifting hurriedly by in the fog seem as if they were not going and coming from stores, offices and factories. As if they were solitaries hunting something in the labyrinths of the fog.

Yes, we are all lost and wandering in the thick mists. We have no destinations. The city is without outlines. And the drift of figures is a meaningless thing. Figures that are going nowhere and coming from nowhere. A swarm of supernumeraries who are not in the play. Who saunter, dash, scurry, hesitate in search of a part in the play.

This is a curious illusion. I stop and listen to music. Overhead a piano is playing and a voice singing. A song-boosting shop above Monroe and State streets. A ballad of the cheap cabarets. Yet, because it is music, it has a mystery in it.

The fog pictures grow charming. There is an idea in them now. People are detached little decorations etched upon a mist. The cat has eaten up the monstrous clock and people have rid themselves of their routine, which was to tumble and scurry among its cogs and levers. They are done with life, with buying and selling and with the perpetual errand. And they have become a swarm of little ornaments. Men and women denuded of the city. Their outlines posture quaintly in the mist. Their little faces say, "The clock is gone. There is nothing any more to make us alive. So we have become our unconnected selves."
