he could not even begin to explain. He did not walk or climb, fly or swim, crawl or wriggle; yet always experienced a mode of motion partly voluntary and partly involuntary. Of his own condition he could not well judge, for sight of his arms, legs, and torso seemed always cut off by some odd disarrangement of perspective; but he felt that his physical organisation and faculties were somehow marvellously transmuted and obliquely projected—though not without a certain grotesque relationship to his normal proportions and properties.
The abysses were by no means vacant, being crowded with indescribably angled masses of alien-hued substance, some of which appeared to be organic while others seemed inorganic. A few of the organic objects tended to awake vague memories in the back of his mind, though he could form no conscious idea of what they mockingly resembled or suggested. In the later dreams he began to distinguish separate categories into which the organic objects appeared to be divided, and which seemed to involve in each case a radically different species of conduct-pattern and basic motivation. Of these categories one seemed to him to include objects slightly less illogical and irrelevant in their motions than the members of the other categories.
All the objects—organic and inorganic alike—were totally beyond description or even comprehension. Gilman sometimes compared the inorganic masses to prisms, labyrinths, clusters of cubes and planes, and Cyclopean buildings; and the organic things struck him variously as groups of bubbles, octopi, centipedes, living Hindoo idols, and intricate Arabesques roused into a kind of ophidian animation. Everything he saw was unspeakably menacing and horrible; and whenever one of the organic entities appeared by its motions to be noticing him, he felt a stark, hideous fright which generally jolted him awake. Of how the organic entities moved, he could tell no more than of how he moved himself. In time he observed a further mystery—the tendency of certain entities to appear suddenly out of empty space, or to disappear totally with equal suddenness. The shrieking, roaring confusion of sound which permeated the abysses was past all analysis as to pitch, timbre, or rhythm; but seemed to be synchronous with vague visual changes in all the indefinite objects, organic and inorganic alike. Gilman had a constant sense of dread that it might rise to some unbearable degree of intensity during one or another of its obscure, relentlessly inevitable fluctuations.
But it was not in these vortices of complete alienage that he saw Brown Jenkin. That shocking little horror was reserved for certain lighter, sharper dreams which assailed him just before he dropped into the fullest depths of sleep. He would be lying in the dark fighting to keep awake when a faint lambent glow would seem to shimmer around the centuried room, shewing in a violet mist the convergence of angled planes which had seized his brain so insidiously. The horror would appear to pop out of the rat-hole in the corner and patter toward him over the sagging, wide-planked floor with evil expectancy in its tiny, bearded human face—but mercifully, this dream always melted away before the object got close enough to nuzzle him. It had hellishly long, sharp, canine teeth. Gilman tried to stop up the rat-hole every day, but each night the real tenants of the partitions would gnaw away the obstruction, whatever it might be. Once he had the landlord nail tin over it, but the next night the rats gnawed a fresh hole—in making which they pushed or dragged out into the room a curious little fragment of bone.
Gilman did not report his fever to the doctor, for he knew he could not pass the examinations if ordered to the college infirmary when every moment was needed for cramming. As it was, he failed in Calculus D and Advanced General Psychology, though not without hope of making up lost ground before the end of the term. It was in March when the fresh element entered his lighter preliminary dreaming, and the nightmare shape of Brown Jenkin began to be companioned by the nebulous blur which grew more and more to resemble a bent old woman. This addition disturbed him more than he could account for, but finally he decided that it was like an ancient crone whom he had twice actually encountered in the dark tangle of lanes near the abandoned wharves. On those occasions the evil, sardonic, and seemingly unmotivated stare of the beldame had set him almost shivering—especially the first time, when an overgrown rat darting across the shadowed mouth of a neighbouring alley had made him think irrationally of Brown Jenkin. Now, he reflected, those nervous fears were being mirrored in his disordered dreams.
That the influence of the old house was unwholesome, he could not deny; but traces of his early morbid interest still held him there. He argued that the fever alone was responsible for his nightly phantasies, and that when the touch abated he would be free from the monstrous visions. Those visions, however, were of abhorrent vividness and convincingness, and whenever he awaked he retained a vague sense of having undergone much more than he remembered. He was hideously sure that in unrecalled dreams he had talked with both Brown Jenkin and the old woman, and that they had been urging him to go somewhere with them and to meet a third being of greater potency.
Toward the end of March he began to pick up in his mathematics, though other studies bothered him increasingly. He was getting an intuitive knack for solving Riemannian equations, and astonished Professor Upham by his comprehension of fourth-dimensional and other problems which had floored all the rest of the class. One afternoon there was a discussion of possible freakish curvatures in space, and of theoretical points of approach or even contact between our part of the cosmos and various other regions as distant as the farthest stars or the trans-galactic gulfs themselves—or even as fabulously remote as the tentatively conceivable cosmic units beyond the whole Einsteinian space-time continuum. Gilman’s handling of this theme filled everyone with admiration, even though some of his hypothetical illustrations caused an increase in the always plentiful gossip about his nervous and solitary eccentricity. What made the students shake their heads was his sober theory that a man might—given mathematical knowledge admittedly beyond all likelihood of human acquirement—step deliberately from the earth to any other celestial body which might lie at one of an infinity of specific points in the cosmic pattern.
Such a step, he said, would require only two stages; first, a passage out of the three-dimensional sphere we know, and second, a passage back to the three-dimensional sphere at another point, perhaps one of infinite remoteness. That this could be accomplished without loss of life was in many cases conceivable. Any being from any part of three-dimensional space could probably survive in the fourth dimension; and its survival of the second stage would depend upon what alien part of three-dimensional space it might select for its re-entry. Denizens of some planets might be able to live on certain others—even planets belonging to other galaxies, or to similar-dimensional phases of other space-time continua—though of course there must be vast numbers of mutually uninhabitable even though mathematically juxtaposed bodies or zones of space.
It was also possible that the inhabitants of a given dimensional realm could survive entry to many unknown and incomprehensible realms of additional or indefinitely multiplied dimensions—be they within or outside the given space-time continuum—and that the converse would be likewise true. This was a matter for speculation, though one could be fairly certain that the type of mutation involved in a passage from any given dimensional plane to the next higher plane would not be destructive of biological integrity as we understand it. Gilman could not be very clear about his reasons for this last assumption, but his haziness here was more than overbalanced by his clearness on other complex points. Professor Upham especially liked his demonstration of the kinship of higher mathematics to certain phases of magical lore transmitted down the ages from an ineffable antiquity—human or pre-human—whose knowledge of the cosmos and its laws was greater than ours.
Around the first of April Gilman worried considerably because his slow fever did not abate. He was also troubled by what some of his fellow-lodgers said about his sleep-walking. It seemed that he was often absent from his bed, and that the creaking of his floor at certain hours of the night was remarked by the man in the room below. This fellow also spoke of hearing the tread of shod feet in the night; but Gilman was sure he must have been mistaken in this, since shoes as well as other apparel were always precisely in place in the morning. One could develop all sorts of aural delusions in this morbid old house—for did not Gilman himself, even in daylight, now feel certain that noises other than rat-scratchings came from the black voids beyond the slanting wall and above the slanting ceiling? His pathologically sensitive ears began to listen for faint footfalls in the immemorially sealed loft overhead, and sometimes the illusion of such things was agonisingly realistic.
However, he knew that he had
