me that an incontrovertible array of facts pointed to some lingering influence in the shunned house; traceable to one or another of the ill-favored French settlers of two centuries before, and still operative through rare and unknown laws of atomic and electronic motion. That the family of Roulet had possessed an abnormal affinity for outer circles of entity—dark spheres which for normal folk hold only repulsion and terror—their recorded history seemed to prove. Had not, then, the riots of those bygone seventeen-thirties set moving certain kinetic patterns in the morbid brain of one or more of them— notably the sinister Paul Roulet—which obscurely survived the bodies murdered and buried by the mob, and continued to function in some multiple-dimensioned space along the original lines of force determined by a frantic hatred of the encroaching community?
Such a thing was surely not a physical or biochemical impossibility in the light of a newer science which includes the theories of relativity and intra-atomic action. One might easily imagine an alien nucleus of substance or energy, formless or otherwise, kept alive by imperceptible or immaterial subtractions from the life-force or bodily tissue and fluids of other and more palpably living things into which it penetrates and with whose fabric it sometimes completely merges itself. It might be actively hostile, or it might be dictated merely by blind motives of self-preservation. In any case such a monster must of necessity be in our scheme of things an anomaly and an intruder, whose extirpation forms a primary duty with every man not an enemy to the world's life, health, and sanity.
What baffled us was our utter ignorance of the aspect in which we might encounter the thing. No sane person had ever seen it, and few had ever felt it definitely. It might be pure energy—a form ethereal and outside the realm of substance—or it might be partly material; some unknown and equivocal mass of plasticity, capable of changing at will to nebulous approximations of the solid, liquid, gaseous, or tenuously unparticled states. The anthropomorphic patch of mold on the floor, the form of the yellowish vapor, and the curvature of the tree-roots in some of the old tales, all argued at least a remote and reminiscent connection with the human shape; but how representative or permanent that similarity might be, none could say with any kind of certainty.
We had devised two weapons to fight it; a large and specially fitted Crookes tube operated by powerful storage batteries and provided with peculiar screens and reflectors, in case it proved intangible and opposable only by vigorously destructive ether radiations, and a pair of military flame-throwers of the sort used in the World War, in case it proved partly material and susceptible of mechanical destruction—for like the superstitious Exeter rustics, we were prepared to burn the thing's heart out if heart existed to burn. All this aggressive mechanism we set in the cellar in positions carefully arranged with reference to the cot and chairs, and to the spot before the fireplace where the mold had taken strange shapes. That suggestive patch, by the way, was only faintly visible when we placed our furniture and instruments, and when we returned that evening for the actual vigil. For a moment I half doubted that I had ever seen it in the more definitely limned form—but then I thought of the legends.
Our cellar vigil began at ten p. m., daylight saving time, and as it continued we found no promise of pertinent developments. A weak, filtered glow from the rain-harassed street-lamps outside, and a
