There beneath you is the monster, stretching acre upon acre into the far distance. High over head hangs the stagnant pall of its fetid breath, reddened with light from myriad eyes endlessly, everywhere blinking. Thousands of acres of cellular tissue, the city’s flesh outspreads layer upon layer, enmeshed by an intricate network of veins and arteries radiating into the gloom, and in them, with muffled, persistent roar, circulating as the blood circulates in your veins, is the almost ceaseless beat of the activity to whose necessities it all conforms. The poisonous waste is drawn from the system of this gigantic creature by infinitely ramifying, thread-like ducts, gathering at their sensitive terminals matter destructive of its life, hurrying it to millions of small intestines to be collected in turn by larger, flowing to the great sewers, on to the drainage canal, and finally to the ocean.
