As the bus reached a lower level I began to catch the steady note of a waterfall through the unnatural stillness. The leaning, unpainted houses grew thicker, lined both sides of the road, and displayed more urban tendencies than did those we were leaving behind, The panorama ahead had contracted to a street scene, and in spots I could see where a cobblestone pavement and stretches of brick sidewalk had formerly existed. All the houses were apparently deserted, and there were occasional gaps where tumbledown chimneys and cellar walls told of buildings that had collapsed. Pervading everything was the most nauseous fishy odour imaginable.
