The afternoon of my search brought nothing to light, and dusk came as I stood on Maple Hill looking down at the hamlet and across the valley to Tempest Mountain. There had been a gorgeous sunset, and now the moon came up, nearly full and shedding a silver flood over the plain, the distant mountainside, and the curious low mounds that rose here and there. It was a peaceful Arcadian scene, but knowing what it hid I hated it. I hated the mocking moon, the hypocritical plain, the festering mountain, and those sinister mounds. Everything seemed to me tainted with a loathsome contagion, and inspired by a noxious alliance with distorted hidden powers.
Presently, as I gazed abstractedly at the moonlit panorama, my eye became attracted by something singular in the nature and arrangement of a certain topographical element. Without having any exact knowledge of geology, I had from the first been interested in the odd mounds and hummocks of the region. I had noticed that they were pretty widely distributed around Tempest Mountain, though less numerous on the plain than near the hilltop itself, where prehistoric glaciation had doubtless found feebler opposition to its striking and fantastic caprices. Now, in the light of that low moon which cast long weird shadows, it struck me forcibly that the various points and lines of the mound system had a peculiar relation to the summit of Tempest Mountain. That summit was undeniably a center from which the lines or rows of points radiated indefinitely and irregularly, as if the unwholesome Martense mansion had thrown out visible tentacles of terror. The idea of such tentacles gave me an unexplained thrill, and I stopped to analyze my reason for believing these mounds glacial phenomena.
The more I analyzed the less I believed, and against my newly opened mind there began to beat grotesque and horrible analogies based on superficial aspects and upon my experience beneath the earth. Before I knew it I was uttering frenzied and disjointed words to myself: "My God! ... Molehills ... the damned place must be honeycombed ... how many ... that night at the mansion ... they took Bennett and Tobey first ... on each side of us." ... Then I was digging frantically into the mound which had stretched nearest me; digging desperately, shiveringly, but almost jubilantly; digging and at last shrieking aloud with some unplaced emotion as I came upon a tunnel or burrow just like the one through which I had crawled on that other demoniac night.
After that I recall running, spade in hand; a hideous run across moon-litten, mound-marked meadows and through diseased, precipitous abysses of haunted hillside forest; leaping, screaming, panting, bounding toward the terrible Martense mansion. I recall digging unreasoningly in all parts of the brier-choked cellar; digging to find the core and center of that malignant universe of mounds. And then I recall how I laughed when I stumbled on the passageway; the hole at the base of the old chimney, where the thick weeds grew and cast queer shadows in the light of the lone candle I had happened to have with me. What still remained down in that hell-hive, lurking and waiting for the thunder to arouse it, I did not know. Two had been killed; perhaps that had finished it. But still there remained that burning determination to reach the innermost secret of the fear, which I had once more come to deem definite, material, and organic.
My indecisive speculation whether to explore the passage alone and immediately with my pocket-light or to try to assemble a band of squatters for the quest was interrupted after a time by a sudden rush of wind from the outside which blew out the candle and left me in stark blackness. The moon no longer shone through the chinks and apertures above me, and with a sense of fateful alarm I heard the sinister and significant rumble of approaching thunder. A confusion of associated ideas possessed my brain, leading me to grope back toward the farthest corner of the cellar. My eyes, however, never turned away from the horrible opening at the base of the chimney; and I began to get glimpses of the crumbling bricks and unhealthy weeds as faint glows of lightning penetrated the woods outside and illumined the chinks in the upper wall. Every second I was consumed with a mixture of fear and curiosity. What would the storm call forth—or was there anything left for it to call? Guided by a lightning flash I settled myself down behind a dense clump of vegetation, through which I could see the opening without being seen.
If heaven is merciful, it will some day efface from my consciousness the sight that I saw, and let me live my last years in peace. I can not sleep at night now, and have to take opiates when it thunders. The thing came abruptly and unannounced; a demon, ratlike scurrying from pits remote and unimaginable, a hellish panting and stifled grunting, and then from that opening beneath the chimney a burst of multitudinous and leprous life—a loathsome night-spawned flood of organic corruption more devastatingly hideous than the blackest conjurations of mortal madness and morbidity. Seething, stewing, surging, bubbling like serpents' slime it rolled up and out of that yawning hole, spreading like a septic contagion and streaming from the cellar at every point of egress—streaming out to scatter through the accursed midnight forests and strew fear, madness, and death.
God knows how many there were—there must have been thousands. To see the stream of them in that faint, intermittent lightning was shocking. When they had thinned out enough to be glimpsed as separate organisms, I saw that they were dwarfed, deformed hairy devils or apes—monstrous and diabolic caricatures of the monkey tribe. They were so hideously silent; there was hardly a squeal when one of the last stragglers turned with the skill of long practise to make a meal in accustomed fashion on a weaker companion. Others snapped up what it left and ate with slavering relish. Then, in spite of my daze of fright and disgust, my morbid curiosity triumphed; and as the last of the monstrosities oozed up alone from that nether world of unknown nightmare, I drew my automatic pistol and shot it under cover of the thunder.
Shrieking, slithering, torrential shadows of red viscous madness chasing one another through endless, ensanguined corridors of purple fulgurous sky ... formless phantasms and kaleidoscopic mutations of a ghoulish, remembered scene; forests of monstrous overnourished oaks with serpent roots twisting and sucking unnamable juices from an earth verminous with millions of cannibal devils; moundlike tentacles groping from underground nuclei of polypous perversion ... insane lightning over malignant ivied walls and demon arcades choked with fungous vegetation.... Heaven be thanked for the instinct which led me unconscious to places where men dwell; to the peaceful village that slept under the calm stars of clearing skies.
