I imagine that as one penetrated out from some enormous forest of the tropics, the wild beasts would become fewer, the gloom would lighten, and the horror of the place would slowly lift. Yet as one emerges nearer to the edge of London, and nearer to the beautiful influence of the hills, the houses become uglier, the streets viler, the gloom deepens, the errors of civilisation stand bare to the scorn of the fields. Where ugliness reaches the height of its luxuriance, in the dense misery of the place, where one imagines the builder saying, "Here I culminate. Let us give thanks to Satan," there is a bridge of yellow brick, and through it, as through some gate of filigree silver opening on fairyland, one passes into the country.
