Part 4

The delicate fire, that plays and vanishes elsewhere, but cannot vanish in London, has nowhere else so gross and dead a following. Even in the north, where the factory makes a denser cloud, you find the blue close by, and the horizon cleaner, or so it seems. Little distant things on the verge, the lashes of the eyes of earth and sky, are more perceptible than they are in London, even with a west wind. Here the fiery Ariel has no delicate companionship, no one near but Caliban.
