"Do you know what that is?" he whispered, "That is ultra-violet."He chuckled oddly at my surprise. "You thought ultra-violet was invisible, and so it is--but you can see that and many other invisible things now.

  "Listen to me! The waves from that thing are waking a thousand sleeping senses in us; senses which we inherit from aeons of evolution from the state of detached electrons to the state of organic humanity. I have seen the truth, and I intend to show it to you. Do you wonder how it will seem? I will tell you."Here Tillinghast seated himself directly opposite me, blowing out his candle and staring hideously into my eyes. "Your existing sense-organs--ears first, I think--will pick up many of the impressions, for they are closely connected with the dormant organs. Then there will be others. You have heard of the pineal gland? I laugh at the shallow endocrinologist, fellow-dupe and fellow-parvenu of the Freudian. That gland is the great sense organ of organs--I have found out. It is like sight in the end, and transmits visual pictures to the brain. If you are normal, that is the way you ought to get most of it...I mean get most of the evidence from beyond."

  I looked about the immense attic room with the sloping south wall, dimly lit by rays which the every day eye cannot see. The far corners were all shadows and the whole place took on a hazy unreality which obscured its nature and invited the imagination to symbolism and phantasm. During the interval that Tillinghast was long silent I fancied myself in some vast incredible temple of long-dead gods; some vague edifice of innumerable black stone columns reaching up from a floor of damp slabs to a cloudy height beyond the range of my vision. The picture was very vivid for a while, but gradually gave way to a more horrible conception; that of utter, absolute solitude in infinite, sightless, soundless space. There seemed to be a void, and nothing more, and I felt a childish fear which prompted me to draw from my hip pocket the revolver I carried after dark since the night I was held up in East Providence. Then from the farthermost regions of remoteness, the sound softly glided into existence. It was infinitely faint, subtly vibrant, and unmistakably musical, but held a quality of surpassing wildness which made its impact feel like a delicate torture of my whole body. I felt sensations like those one feels when accidentally scratching ground glass. Simultaneously there developed something like a cold draught, which apparently swept past me from the direction of the distant sound. As I waited breathlessly I perceived that both sound and wind were increasing; the effect being to give me an odd notion of myself as tied to a pair of rails in the path of a gigantic approaching locomotive. I began to speak to Tillinghast, and as I did so all the unusual impressions abruptly vanished. I saw only the man, the glowing machines, and the dim apartment. Tillinghast was grinning repulsively at the revolver which I had almost unconsciously drawn, but from his expression I was sure he had seen and heard as much as I, if not a great deal more. I whispered what I had experienced and he bade me to remain as quiet and receptive as possible.

  "Don't move," he cautioned, "for in these rays we are able to be seen as well as to see. I told you the servants left, but I didn't tell you how. It was that thick-witted house-keeper--she turned on the lights downstairs after I had warned her not to, and the wires picked up sympathetic vibrations. It must have been frightful--I could hear the screams up here in spite of all I was seeing and hearing from another direction, and later it was rather awful to find those empty heaps of clothes around the house. Mrs. Updike's clothes were close to the front hall switch--that's how I know she did it. It got them all. But so long as we don't move we're fairly safe. Remember we're dealing with a hideous world in which we are practically helpless...Keep still!"

  The combined shock of the revelation and of the abrupt command gave me a kind of paralysis, and in my terror my mind again opened to the impressions coming from what Tillinghast called "beyond."I was now in a vortex of sound and motion, with confused pictures before my eyes. I saw the blurred outlines of the room, but from some point in space there seemed to be pouring a seething column of unrecognizable shapes or clouds, penetrating the solid roof at a point ahead and to the right of me. Then I glimpsed the temple-like effect again, but this time the pillars reached up into an aerial ocean of light, which sent down one blinding beam along the path of the cloudy column I had seen before. After that the scene was almost wholly kaleidoscopic, and in the jumble of sights, sounds, and unidentified sense-impressions I felt that I was about to dissolve or in some way lose the solid form. One definite flash I shall always remember. I seemed for an instant to behold a patch of strange night sky filled with shining, revolving spheres, and as it receded I saw that the glowing suns formed a constellation or galaxy of settled shape; this shape being the distorted face of Crawford Tillinghast. At another time I felt the huge animate things brushing past me and occasionally walking or drifting through my supposedly solid body, and thought I saw Tillinghast look at them as though his better trained senses could catch them visually. I recalled what he had said of the pineal gland, and wondered what he saw with this preternatural eye.

  Suddenly I myself became possessed of a kind of augmented sight. Over and above the luminous and shadowy chaos arose a picture which, though vague, held the elements of consistency and permanence. It was indeed somewhat familiar, for the unusual part was superimposed upon the usual terrestrial scene much as a cinema view may be thrown upon the painted curtain of a theater. I saw the attic laboratory, the electrical machine, and the unsightly form of Tillinghast opposite me; but of all the space unoccupied by familiar objects not one particle was vacant. Indescribable shapes both alive and otherwise were mixed in disgusting disarray, and close to every known thing were whole worlds of alien, unknown entities. It likewise seemed that all the known things entered into the composition of other unknown things and vice versa. Foremost among the living objects were inky, jellyfish monstrosities which flabbily quivered in harmony with the vibrations from the machine. They were present in loathsome profusion, and I saw to my horror that they overlapped; that they were semi-fluid and capable of passing through one another and through what we know as solids. These things were never still, but seemed ever floating about with some malignant purpose. Sometimes they appeared to devour one another, the attacker launching itself at its victim and instantaneously obliterating the latter from sight. Shudderingly I felt that I knew what had obliterated the unfortunate servants, and could not exclude the thing from my mind as I strove to observe other properties of the newly visible world that lies unseen around us. But Tillinghast had been watching me and was speaking.

  "You see them? You see them? You see the things that float and flop about you and through you every moment of your life? You see the creatures that form what men call the pure air and the blue sky? Have I not succeeded in breaking down the barrier; have I not shown you worlds that no other living men have seen?" I heard his scream through the horrible chaos, and looked at the wild face thrust so offensively close to mine. His eyes were pits of flame, and they glared at me with what I now saw was overwhelming hatred. The machine droned detestably.

  "You think those floundering things wiped out the servants? Fool, they are harmless! But the servants are gone, aren't they? You tried to stop me; you discouraged me when I needed every drop of encouragement I could get; you were afraid of the cosmic truth, you damned coward, but now I've got you! What swept up the servants? What made them scream so loud?...Don't know, eh! You'll know soon enough. Look at me--listen to what I say--do you suppose there are really any such things as time and magnitude? Do you fancy there are such things as form or matter? I tell you, I have struck depths that your little brain can't picture. I have seen beyond the bounds of infinity and drawn down demons from the stars...I have harnessed the shadows that stride from world to world to sow death and madness...Space belongs to me, do you hear? Things are hunting me now--the things that devour and dissolve--but I know how to elude them. It is you they will get, as they got the servants...Stirring, dear sir? I told you it was dangerous to move, I have saved you so far by telling you to kee
p still--saved you to see more sights and to listen to me. If you had moved, they would have been at you long ago. Don't worry, they won't hurt you. They didn't hurt the servants--it was the seeing that made the poor devils scream so. My pets are not pretty, for they come out of places where aesthetic standards are--very different. Disintegration is quite painless, I assure you--but I want you to see them. I almost saw them, but I knew how to stop. You are curious? I always knew you were no scientist. Trembling, eh. Trembling with anxiety to see the ultimate things I have discovered. Why don't you move, then? Tired? Well, don't worry, my friend, for they are coming...Look, look, curse you, look...it's just over your left shoulder..."

  What remains to be told is very brief, and may be familiar to you from the newspaper accounts. The police heard a shot in the old Tillinghast house and found us there--Tillinghast dead and me unconscious. They arrested me because the revolver was in my hand, but released me in three hours, after they found it was apoplexy which had finished Tillinghast and saw that my shot had been directed at the noxious machine which now lay hopelessly shattered on the laboratory floor. I did not tell very much of what I had seen, for I feared the coroner would be skeptical; but from the evasive outline I did give, the doctor told me that I had undoubtedly been hypnotized by the vindictive and homicidal madman.

  I wish I could believe that doctor. It would help my shaky nerves if I could dismiss what I now have to think of the air and the sky about and above me. I never feel alone or comfortable, and a hideous sense of pursuit sometimes comes chillingly on me when I am weary. What prevents me from believing the doctor is one simple fact--that the police never found the bodies of those servants whom they say Crawford Tillinghast murdered.

  HE

  I saw him on a sleepless night when I was walking desperately to save my soul and my vision. My coming to New York had been a mistake; for whereas I had looked for poignant wonder and inspiration in the teeming labyrinths of ancient streets that twist endlessly from forgotten courts and squares and waterfronts to courts and squares and waterfronts equally forgotten, and in the Cyclopean modern towers and pinnacles that rise blackly Babylonian under waning moons, I had found instead only a sense of horror and oppression which threatened to master, paralyze, and annihilate me.

  The disillusion had been gradual. Coming for the first time upon the town, I had seen it in the sunset from a bridge, majestic above its waters, its incredible peaks and pyramids rising flowerlike and delicate from pools of violet mist to play with the flaming clouds and the first stars of evening. Then it had lighted up window by window above the shimmering tides where lanterns nodded and glided and deep horns bayed weird harmonies, and had itself become a starry firmament of dream, redolent of faery music, and one with the marvels of Carcassonne and Samarcand and El Dorado and all glorious and half- fabulous cities. Shortly afterward I was taken through those antique ways so dear to my fancy--narrow, curving alleys and passages where rows of red Georgian brick blinked with small-paned dormers above pillared doorways that had looked on gilded sedans and paneled coaches--and in the first flush of realization of these long-wished things I thought I had indeed achieved such treasures as would make me in time a poet.

  But success and happiness were not to be. Garish daylight showed only squalor and alienage and the noxious elephantiasis of climbing, spreading stone where the moon had hinted of loveliness and elder magic; and the throngs of people that seethed through the flume-like streets were squat, swarthy strangers with hardened faces and narrow eyes, shrewd strangers without dreams and without kinship to the scenes about them, who could never mean aught to a blue-eyed man of the old folk, with the love of fair green lanes and white New England village steeples in his heart.

  So instead of the poems I had hoped for, there came only a shuddering blackness and ineffable loneliness; and I saw at last a fearful truth which no one had ever dared to breathe before--the unwhisperable secret of secrets--the fact that this city of stone and stridor is not a sentient perpetuation of Old New York as London is of Old London and Paris of Old Paris, but that it is in fact quite dead, its sprawling body imperfectly embalmed and infested with queer animate things which have nothing to do with it as it was in life. Upon making this discovery I ceased to sleep comfortably; though something of resigned tranquillity came back as I gradually formed the habit of keeping off the streets by day and venturing abroad only at night, when darkness calls forth what little of the past still hovers wraith-like about, and old white doorways remember the stalwart forms that once passed through them. With this mode of relief I even wrote a few poems, and still refrained from going home to my people lest I seem to crawl back ignobly in defeat.

  Then, on a sleepless night's walk, I met the man. It was in a grotesque hidden courtyard of the Greenwich section, for there in my ignorance I had settled, having heard of the place as the natural home of poets and artists. The archaic lanes and houses and unexpected bits of square and court had indeed delighted me, and when I found the poets and artists to be loud-voiced pretenders whose quaintness is tinsel and whose lives are a denial of all that pure beauty which is poetry and art, I stayed on for love of these venerable things. I fancied them as they were in their prime, when Greenwich was a placid village not yet engulfed by the town; and in the hours before dawn, when all the revellers had slunk away, I used to wander alone among their cryptical windings and brood upon the curious arcana which generations must have deposited there. This kept my soul alive, and gave me a few of those dreams and visions for which the poet far within me cried out.

  The man came upon me at about two one cloudy August morning, as I was threading a series of detached courtyards; now accessible only through the unlighted hallways of intervening buildings, but once forming parts of a continuous network of picturesque alleys. I had heard of them by vague rumor, and realized that they could not be upon any map of today; but the fact that they were forgotten only endeared them to me, so that I had sought them with twice my usual eagerness. Now that I had found them, my eagerness was again redoubled; for something in their arrangement dimly hinted that they might be only a few of many such, with dark, dumb counterparts wedged obscurely betwixt high blank walls and deserted rear tenements, or lurking lamplessly behind archways unbetrayed by hordes of the foreign-speaking or guarded by furtive and uncommunicative artists whose practises do not invite publicity or the light of day.

  He spoke to me without invitation, noting my mood and glances as I studied certain knockered doorways above iron-railed steps, the pallid glow of traceried transoms feebly lighting my face. His own face was in shadow, and he wore a wide-brimmed hat which somehow blended perfectly with the out-of-date cloak he affected; but I was subtly disquieted even before he addressed me. His form was very slight; thin almost to cadaverousness; and his voice proved phenomenally soft and hollow, though not particularly deep. He had, he said, noticed me several times at my wanderings; and inferred that I resembled him in loving the vestiges of former years. Would I not like the guidance of one long practised in these explorations, and possessed of local information profoundly deeper than any which an obvious newcomer could possibly have gained?

  As he spoke, I caught a glimpse of his face in the yellow beam from a solitary attic window. It was a noble, even a handsome elderly countenance; and bore the marks of a lineage and refinement unusual for the age and place. Yet some quality about it disturbed me almost as much as its features pleased me--perhaps it was too white, or too expressionless, or too much out of keeping with the locality, to make me feel easy or comfortable. Nevertheless I followed him; for in those dreary days my quest for antique beauty and mystery was all that I had to keep my soul alive, and I reckoned it a rare favor of Fate to fall in with one whose kindred seekings seemed to have penetrated so much farther than mine.

  Something in the night constrained the cloaked man to silence and for a long hour he led me forward without needless words; making only the briefest of comments concerning ancient names and dates and changes,
and directing my progress very largely by gestures as we squeezed through interstices, tiptoed through corridors clambered over brick walls, and once crawled on hands and knees through a low, arched passage of stone whose immense length and tortuous twistings effaced at last every hint of geographical location I had managed to preserve. The things we saw were very old and marvelous, or at least they seemed so in the few straggling rays of light by which I viewed them, and I shall never forget the tottering Ionic columns and fluted pilasters and urn-headed iron fenceposts and flaring-linteled windows and decorative fanlights that appeared to grow quainter and stranger the deeper we advanced into this inexhaustible maze of unknown antiquity.

  We met no person, and as time passed the lighted windows became fewer and fewer. The streetlights we first encountered had been of oil, and of the ancient lozenge pattern. Later I noticed some with candles; and at last, after traversing a horrible unlighted court where my guide had to lead with his gloved hand through total blackness to a narrow wooded gate in a high wall, we came upon a fragment of alley lit only by lanterns in front of every seventh house--unbelievably Colonial tin lanterns with conical tops and holes punched in the sides. This alley led steeply uphill--more steeply than I thought possible in this part of New York--and the upper end was blocked squarely by the ivy-clad wall of a private estate, beyond which I could see a pale cupola, and the tops of trees waving against a vague lightness in the sky. In this wall was a small, low-arched gate of nail-studded black oak, which the man proceeded to unlock with a ponderous key. Leading me within, he steered a course in utter blackness over what seemed to be a gravel path, and finally up a flight of stone steps to the door of the house, which he unlocked and opened for me.
