Yet I soon subordinated all my fears to my growing curiosity and fascination. Just what Crawford Tillinghast now wished of me I could only guess, but that he had some stupendous secret or discovery to impart, I could not doubt. Before I had protested at his unnatural pryings into the unthinkable; now that he had evidently succeeded to some degree I almost shared his spirit, terrible though the cost of victory appeared. Up through the dark emptiness of the house I followed the bobbing candle in the hand of this shaking parody on man. The electricity seemed to be turned off, and when I asked my guide he said it was for a definite reason.
“It would he too much . . . I would not dare,” he contin-ued to mutter. I especially noted his new habit of muttering, for it was not like him to talk to himself. We entered the laboratory in the attic, and I observed that detestable elec-trical machine, glowing with a sickly, sinister violet luminos-ity. It was connected with a powerful chemical battery, but seemed to be receiving no current; for I recalled that in experimental stage it had sputtered and purred when in action. In reply to my question Tillinghast mumbled that this permanent glow was not electrical in any sense that I could understand.
He now seated me near the machine, so that it was on my right, and turned a switch somewhere below the crowning cluster of glass bulbs. The usual sputtering began, turned to a whine, and terminated in a drone so soft as to suggest a return to silence. Meanwhile the luminosity increased, waned again, then assumed a pale, ontre colour or blend of colours which I could neither place nor describe. Tillinghast had been watching me, and noted my puzzled expression.
“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 Trninghast 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 in-vited 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 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 musi-cal, 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 ef-fect 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 re-main as quiet and receptive as possible.
