The luminous yellow vapour had now risen a height of ten or fifteen feet, and formed a roof both over the land and over the red water, under which it was possible to see for a great distance. The surface of the red oil or viscid liquid was perfectly smooth, and, indeed, it did not seem as if any wind could rouse a wave on it, much less that a swell should be left after the gale had gone down. Disappointed in his search for water to drink, Felix mechanically turned to go back.
He followed his luminous footmarks, which he could see a long way before him. His trail curved so much that he made many shortcuts across the winding line he had left. His weariness was now so intense that all feeling had departed. His feet, his limbs, his arms, and hands were numbed. The subtle poison of the emanations from the earth had begun to deaden his nerves. It seemed a full hour or more to him till he reached the spot where the skeletons were drawn in white upon the ground.
He passed a few yards to one side of them, and stumbled over a heap of something which he did not observe, as it was black like the level ground. It emitted a metallic sound, and looking he saw that he had kicked his foot against a great heap of money. The coins were black as ink; he picked up a handful and went on. Hitherto Felix had accepted all that he saw as something so strange as to be unaccountable. During his advance into this region in the canoe he had in fact become slowly stupefied by the poisonous vapour he had inhaled. His mind was partly in abeyance; it acted, but only after some time had elapsed. He now at last began to realize his position; the finding of the heap of blackened money touched a chord of memory. These skeletons were the miserable relics of men who had ventured, in search of ancient treasures, into the deadly marshes over the site of the mightiest city of former days. The deserted and utterly extinct city of London was under his feet.
He had penetrated into the midst of that dreadful place, of which he had heard many a tradition: how the earth was poison, the water poison, the air poison, the very light of heaven, falling through such an atmosphere, poison. There were said to be places where the earth was on fire and belched forth sulphurous fumes, supposed to be from the combustion of the enormous stores of strange and unknown chemicals collected by the wonderful people of those times. Upon the surface of the water there was a greenish-yellow oil, to touch which was death to any creature; it was the very essence of corruption. Sometimes it floated before the wind, and fragments became attached to reeds or flags far from the place itself. If a moorhen or duck chanced to rub the reed, and but one drop stuck to its feathers, it forthwith died. Of the red water he had not heard, nor of the black, into which he had unwittingly sailed.
Ghastly beings haunted the site of so many crimes, shapeless monsters, hovering by night, and weaving a fearful dance. Frequently they caught fire, as it seemed, and burned as they flew or floated in the air. Remembering these stories, which in part, at least, now seemed to be true, Felix glanced aside, where the cloud still kept pace with him, and involuntarily put his hands to his ears lest the darkness of the air should whisper some horror of old times. The earth on which he walked, the black earth, leaving phosphoric footmarks behind him, was composed of the mouldered bodies of millions of men who had passed away in the centuries during which the city existed. He shuddered as he moved; he hastened, yet could not go fast, his numbed limbs would not permit him.
He dreaded lest he should fall and sleep, and wake no more, like the searchers after treasure; treasure which they had found only to lose forever. He looked around, supposing that he might see the gleaming head and shoulders of the half-buried giant, of which he recollected he had been told. The giant was punished for some crime by being buried to the chest in the earth; fire incessantly consumed his head and played about it, yet it was not destroyed. The learned thought, if such a thing really existed, that it must be the upper part of an ancient brazen statue, kept bright by the action of acid in the atmosphere, and shining with reflected light. Felix did not see it, and shortly afterwards surmounted the hill, and looked down upon his canoe. It was on fire!

Fiery Vapours
Felix tried to run, but his feet would not rise from the ground; his limbs were numb as in a nightmare; he could not get there. His body would not obey his will. In reality he did move, but more slowly than when he walked. By degrees approaching the canoe his alarm subsided, for although it burned it was not injured; the canvas of the sail was not even scorched. When he got to it the flames had disappeared; like Jack-o’-the-lantern, the phosphoric fire receded from him. With all his strength he strove to launch her, yet paused, for over the surface of the black water, now smooth and waveless, played immense curling flames, stretching out like endless serpents, weaving, winding, rolling over each other. Suddenly they contracted into a ball, which shone with a steady light, and was as large as the full moon. The ball swept along, rose a little, and from it flew out long streamers till it was unwound in fiery threads.
But remembering that the flames
