Yet after all, the sight was worse than I had dreaded. There are horrors beyond horrors, and this was one of those nuclei of all dreamable hideousness which the cosmos saves to blast an accursed and unhappy few. Out of the fungus-ridden earth steamed up a vaporous corpse-light, yellow and diseased, which bubbled and lapped to a gigantic height in vague outlines half-human and half-monstrous, through which I could see the chimney and fireplace beyond. It was all eyes — wolfish and mocking — and the rugose insect-like head dissolved at the top to a thin stream of mist which curled putridly about and finally vanished up the chimney. I say that I saw this thing, but it is only in conscious retrospection that I ever definitely traced its damnable approach to form. At the time it was to me only a seething, dimly phosphorescent cloud of fungous loathsomeness, enveloping and dissolving to an abhorrent plasticity the one object to which all my attention was focussed. That object was my uncle — the venerable Elihu Whipple — who with blackening and decaying features leered and gibbered at me, and reached out dripping claws to rend me in the fury which this horror had brought.
It was a sense of routine which kept me from going mad. I had drilled myself in preparation for the crucial moment, and blind training saved me. Recognising the bubbling evil as no substance reachable by matter or material chemistry, and therefore ignoring the flame-thrower which loomed on my left, I threw on the current of the Crookes tube apparatus, and focussed toward that scene of immortal blasphemousness the strongest ether radiations which man’s art can arouse from the spaces and fluids of Nature. There was a bluish haze and a frenzied sputtering, and the yellowish phosphorescence grew dimmer to my eyes. But I saw the dimness was only that of contrast, and that the waves from the machine had no effect whatever.
Then, in the midst of that daemoniac spectacle, I saw a fresh horror which brought cries to my lips and sent me fumbling and staggering toward that unlocked door to the quiet street, careless of what abnormal terrors I loosed upon the world, or what thoughts or judgments of men I brought down upon my head. In that dim blend of blue and yellow the form of my uncle had commenced a nauseous liquefaction whose essence eludes all description, and in which there played across his vanishing face such changes of identity as only madness can conceive. He was at once a devil and a multitude, a charnel-house and a pageant. Lit by the mixed and uncertain beams, that gelatinous face assumed a dozen — a score — a hundred — aspects; grinning, as it sank to the ground on a body that melted like tallow, in the caricatured likeness of legions strange and yet not strange.
I saw the features of the Harris line, masculine and feminine, adult and infantile, and other features old and young, coarse and refined, familiar and unfamiliar. For a second there flashed a degraded counterfeit of a miniature of poor mad Rhoby Harris that I had seen in the School of Design Museum, and another time I thought I caught the raw-boned image of Mercy Dexter as I recalled her from a painting in Carrington Harris’s house. It was frightful beyond conception; toward the last, when a curious blend of servant and baby visages flickered close to the fungous floor where a pool of greenish grease was spreading, it seemed as though the shifting features fought against themselves, and strove to form contours like those of my uncle’s kindly face. I like to think that he existed at that moment, and that he tried to bid me farewell. It seems to me I hiccoughed a farewell from my own parched throat as I lurched out into the street; a thin stream of grease following me through the door to the rain-drenched sidewalk.
The rest is shadowy and monstrous. There was no one in the soaking street, and in all the world there was no one I dared tell. I walked aimlessly south past College Hill and the Athenaeum, down Hopkins Street, and over the bridge to the business section where tall buildings seemed to guard me as modern material things guard the world from ancient and unwholesome wonder. Then grey dawn unfolded wetly from the east, silhouetting the archaic hill and its venerable steeples, and beckoning me to the place where my terrible work was still unfinished. And in the end I went, wet, hatless, and dazed in the morning light, and entered that awful door in Benefit Street which I had left ajar, and which still swung cryptically in full sight of the early householders to whom I dared not speak.
The grease was gone, for the mouldy floor was porous. And in front of the fireplace was no vestige of the giant doubled-up form in nitre. I looked at the cot, the chairs, the instruments, my neglected hat, and the yellowed straw hat of my uncle. Dazedness was uppermost, and I could scarcely recall what was dream and what was reality. Then thought trickled back, and I knew that I had witnessed things more horrible than I had dreamed. Sitting down, I tried to conjecture as nearly as sanity would let me just what had happened, and how I might end the horror, if indeed it had been real. Matter it seemed not to be, nor ether, nor anything else conceivable by mortal mind. What, then, but some exotic emanation; some vampirish vapour such as Exeter rustics tell of as lurking over certain churchyards? This I felt was the clue, and again I looked at the floor before the fireplace where the mould and nitre had taken strange forms. In ten minutes my mind was made up, and taking my hat I set out for home, where I bathed, ate, and gave by telephone an order for a pickaxe, a spade, a military gas-mask, and six carboys of sulphuric acid, all to be delivered the next morning at the cellar door of the shunned house in Benefit Street. After that I tried to sleep; and failing, passed the hours in reading and in the composition of inane verses to counteract my mood.
