But I do not wonder at the horror caused--for certainly, the mind, voice, and facial expression of the being that awakened on l5 May 1908, were not those of Nathaniel Wingate Peastee.

  I will not attempt to tell much of my life from 1908 to 1913, since readers may glean I the outward essentials--as I largely had to do--from files of old newspapers and scientific journals.

  I was given charge of my funds, and spent them slowly and on the whole wisely, in travel and in study at various centres of learning. My travels, however, were singular in the extreme, involving long visits to remote and desolate places.

  In 1909 I spent a month in the Himalayas, and in 1911 roused much attention through a camel trip into the unknown deserts of Arabia. What happened on those journeys I have never been able to learn.

  During the summer of l9l2 I chartered a ship and sailed in the Arctic, north of Spitzbergen, afterward showing signs of disappointment.

  Later in that year I spent weeks--alone beyond the limits of previous or subsequent exploration in the vast limestone cavern systems of western Virginia--black labyrinths so complex that no retracing of my steps could even be considered.

  My sojourns at the universities were marked by abnormally rapid assimilation, as if the secondary personality had an intelligence enormously superior to my own. I have found, also, that my rate of reading and solitary study was phenomenal. I could master every detail of a book merely by glancing over it as fast as I could turn the leaves; while my skill at interpreting complex figures in an instant was veritably awesome.

  At times there appeared almost ugly reports of my power to influence the thoughts and acts of others, though I seemed to have taken care to minimize displays of this faculty.

  Other ugly reports concerned my intimacy with leaders of occultist groups, and scholars suspected of connection with nameless bands of abhorrent elder-world hierophants. These rumours, though never proved at the time, were doubtless stimulated by the known tenor of some of my reading--for the consultation of rare books at libraries cannot be effected secretly.

  There is tangible proof--in the form of marginal notes--that I went minutely through such things as the Comte d'Erlette's Cultes des Goules, Ludvig Prinn's De Vermis Mysteriis, the Unaussprechlichen Kulten of von Junzt, the surviving fragments of the puzzling Book of Eibon, and the dreaded Necronomicon of the mad Arab Abdul Alhazred. Then, too, it is undeniable that a fresh and evil wave of underground cult activity set in about the time of my odd mutation.

  In the summer of 1913 I began to display signs of ennui and flagging interest, and to hint to various associates that a change might soon be expected in me. I spoke of returning memories of my earlier life--though most auditors judged me insincere, since all the recollections I gave were casual, and such as might have been learned from my old private papers.

  About the middle of August I returned to Arkham and re-opened my long-closed house in Crane Street. Here I installed a mechanism of the most curious aspect, constructed piecemeal by different makers of scientific apparatus in Europe and America, and guarded carefully from the sight of any one intelligent enough to analyse it.

  Those who did see it--a workman, a servant, and the new housekeeper--say that it was a queer mixture of rods, wheels, and mirros, though only about two feet tall, one foot wide, and one foot thick. The central mirror was circular and convex. All this is borne out by such makers of parts as can be located.

  On the evening of Friday, 26 September, I dismissed the housekeeper and the maid until noon of the next day. Lights burned in the house till late, and a lean, dark, curiously foreign-looking man called in an automobile.

  It was about one A.M. that the lights were last seen. At 2.15 A.M. a policeman observed the place in darkness, but the stranger's motor still at the curb. By 4 o'clock the motor was certainly gone.

  It was at 6 o'clock that a hesitant, foreign voice on the telephone asked Dr Wilson to call at my house and bring me out of a peculiar faint. This call--a long-distance one--was later traced to a public booth in the North Station in Boston, but no sign of the lean foreigner was ever unearthed.

  When the doctor reached my house he found me unconscious in the sitting room--in an easy-chair with a table drawn up before it. On the polished top were scratches showing where some heavy object had rested. The queer machine was gone, nor was anything afterward heard of it. Undoubtedly the dark, lean foreigner had taken it away.

  In the library grate were abundant ashes, evidently left from the burning of every remaining scrap of paper on which I had written since the advent of the amnesia. Dr Wilson found my breathing very peculiar, but after a hypodermic injection it became more regular.

  At 11.15 A.M., 27 September, I stirred vigorously, and my hitherto masklike face began to show signs of expression. Dr Wilson remarked that the expression was not that of my secondary personality, but seemed much like that of my normal self. About 11.30 I muttered some very curious syllables--syllables which seemed unrelated to any human speech. I appeared, too, to struggle against something. Then, just afternoon--the housekeeper and the maid having meanwhile returned--I began to mutter in English.

  "--of the orthodox economists of that period, Jevons typifies the prevailing trend toward scientific correlation. His attempt to link the commercial cycle of prosperity and depression with the physical cycle of the solar spots forms perhaps the apex of--"

  Nathaniel Wingate Peaslee had come back--a spirit in whose time scale it was still Thursday morning in 1908, with the economics class gazing up at the battered desk on the platform.

  II

  My reabsorption into normal life was a painful and difficult process. The loss of over five years creates more complications than can be imagined, and in my case there were countless matters to be adjusted.

  What I heard of my actions since 1908 astonished and disturbed me, but I tried to view the matter as philosophically as I could. At last, regaining custody of my second son, Wingate, I settled down with him in the Crane Street house and endeavoured to resume my teaching--my old professorship having been kindly offered me by the college.

  I began work with the February, 1914, term, and kept at it just a year. By that time I realized how badly my experience had shaken me. Though perfectly sane--I hoped--and with no flaw in my original personality, I had not the nervous energy of the old days. Vague dreams and queer ideas continually haunted me, and when the outbreak of the World War turned my mind to history I found myself thinking of periods and events in the oddest possible fashion.

  My conception of time, my ability to distinguish between consecutiveness and simultaneousness--seemed subtly disordered so that I formed chimerical notions about living in one age and casting one's mind all over eternity for knowledge of past and future ages.

  The war gave me strange impressions of remembering some of its far-off consequences--as if I knew how it was coming out and could look back upon it in the light of future information. All such quasi-memories were attended with much pain, and with a feeling that some artificial psychological barrier was set against them.

  When I diffidently hinted to others about my impressions I met with varied responses. Some persons looked uncomfortably at me, but men in the mathematics department spoke of new developments in those theories of relativity--then discussed only in learned circles--which were later to become so famous. Dr. Albert Einstein, they said, was rapidly reducing time to the status of a mere dimension.

  But the dreams and disturbed feelings gained on me, so that I had to drop my regular work in 1915. Certainly the impressions were taking an annoying shape--giving me the persistent notion that my amnesia had formed some unholy sort of exchange; that the secondary personality had indeed had had suffered displacement.

  Thus I was driven to vague and fright speculations concerning the whereabouts of my true self during the years that another had held my body. The curious knowledge and strange conduct of my body's late tenant troubled me more and more as I learned further details from person
s, papers, and magazines.

  Queernesses that had baffled others seemed to harmonize terribly with some background of black knowledge which festered in the chasms of my subconscious. I began to search feverishly for every scrap of information bearing on the studies and travels of that other one during the dark years.

  Not all of my troubles were as semi-abstract as this. There were the dreams--and these seemed to grow in vividness and concreteness. Knowing how most would regard them, I seldom mentioned them to anyone but my son or certain trusted psychologists, but eventually I commenced a scientific study of other cases in order to see how typical or nontypical such visions might be among amnesia victims.

  My results, aided by psychologists, historians, anthropologists, and mental specialists of wide experience, and by a study that included all records of split personalities from the days of daemonic-possession legends to the medically realistic present, at first bothered me more than they consoled me.

  I soon found that my dreams had, indeed, no counterpart in the overwhelming bulk of true amnesia cases. There remained, however, a tiny residue of accounts which for years baffled and shocked me with their parallelism to my own experience. Some of them were bits of ancient folklore; others were case histories in the annals of medicine; one or two were anecdotes obscurely buried in standard histories.

  It thus appeared that, while my special kind of affliction was prodigiously rare, instances of it had occurred at long intervals ever since the beginning of men's annals. Some centuries might contain one, two, or three cases, others none--or at least none whose record survived.

  The essence was always the same--a person of keen thoughtfulness seized a strange secondary life and leading for a greater or lesser period an utterly alien existence typified at first by vocal and bodily awkwardness, and later by a wholesale acquisition of scientific, historic, artistic, and anthropologic knowledge; an acquisition carried on with feverish zest and with a wholly abnormal absorptive power. Then a sudden return of rightful consciousness, intermittently plagued ever after with vague unplaceable dreams suggesting fragments of some hideous memory elaborately blotted out.

  And the close resemblance of those nightmares to my own--even in some of the smallest particulars--left no doubt in my mind of their significantly typical nature. One or two of the cases had an added ring of faint, blasphemous familiarity, as if I had heard of them before through some cosmic channel too morbid and frightful to contemplate. In three instances there was specific mention of such an unknown machine as had been in my house before the second change.

  Another thing that worried me during my investigation was the somewhat greater frequency of cases where a brief, elusive glimpse of the typical nightmares was afforded to persons not visited with well-defined amnesia.

  These persons were largely of mediocre mind or less--some so primitive that they could scarcely be thought of as vehicles for abnormal scholarship and preternatural mental acquisitions. For a second they would be fired with alien force--then a backward lapse, and a thin, swift-fading memory of unhuman horrors.

  There had been at least three such cases during the past half century--one only fifteen years before. Had something been groping blindly through time from some unsuspected abyss in Nature? Were these faint cases monstrous, sinister experiments of a kind and authorship utterly beyond sane belief?

  Such were a few of the formless speculations of my weaker hours--fancies abetted by myths which my studies uncovered. For I could not doubt but that certain persistent legends of immemorial antiquity, apparently unknown to the victims and physicians connected with recent amnesia cases, formed a striking and awesome elaboration of memory lapses such as mine.

  Of the nature of the dreams and impressions which were growing so clamorous I still almost fear to speak. They seemed to savor of madness, and at times I believed I was indeed going mad. Was there a special type of delusion afflicting those who had suffered lapses of memory? Conceivably, the efforts of the subconscious mind to fill up a perplexing blank with pseudo-memories might give rise to strange imaginative vagaries.

  This indeed--though an alternative folklore theory finally seemed to me more plausible--was the belief of many of the alienists who helped me in my search for parallel cases, and who shared my puzzlement at the exact resemblances sometimes discovered.

  They did not call the condition true insanity, but classed it rather among neurotic disorders. My course in trying to track down and analyze it, instead of vainly seeking to dismiss or forget it, they heartily endorsed as correct according to the best psychological principles. I especially valued the advice of such physicians as had studied me during my possession by the other personality.

  My first disturbances were not visual at all, but concerned the more abstract matters which I have mentioned. There was, too, a feeling of profound and inexplicable horror concerning myself. I developed a queer fear of seeing my own form, as if my eyes would find it something utterly alien and inconceivably abhorrent.

  When I did glance down and behold the familiar human shape in quiet grey or blue clothing, I always felt a curious relief, though in order to gain this relief I had to conquer an infinite dread. I shunned mirrors as much as possible, and was always shaved at the barber's.

  It was a long time before I correlated any of these disappointed feelings with the fleeting visual impressions which began to develop. The first such correlation had to do with the odd sensation of an external, artificial restraint on my memory.

  I felt that the snatches of sight I experienced had a profound and terrible meaning, and a frightful connexion with myself, but that some purposeful influence held me from grasping that meaning and that connexion. Then came that queerness about the element of time, and with it desperate efforts to place the fragmentary dream-glimpses in the chronological and spatial pattern.

  The glimpses themselves were at first merely strange rather than horrible. I would seem to be in an enormous vaulted chamber whose lofty stone groinings were well-nigh lost in the shadows overhead. In whatever time or place the scene might be, the principle of the arch was known as fully and used as extensively as by the Romans.

  There were colossal, round windows and high, arched doors, and pedestals or tables each as tall as the height of an ordinary room. Vast shelves of dark wood lined the walls, holding what seemed to be volumes of immense size with strange hieroglyphs on their backs.

  The exposed stonework held curious carvings, always in curvilinear mathematical designs, and there were chiselled inscriptions in the same characters that the huge books bore. The dark granite masonry was of a monstrous megathic type, with lines of convex-topped blocks fitting the concave-bottomed courses which rested upon them.

  There were no chairs, but the tops of the vast pedestals were littered with books, papers, and what seemed to be writing materials--oddly figured jars of a purplish metal, and rods with stained tips. Tall as the pedestals were, I seemed at times able to view them from above. On some of them were great globes of luminous crystal serving as lamps, and inexplicable machines formed of vitreous tubes and metal rods.

  The windows were glazed, and latticed with stout-looking bars. Though I dared not approach and peer out them, I could see from where I was the waving tops of singular fern-like growths. The floor was of massive octagonal flagstones, while rugs and hangings were entirely lacking.

  Later I had visions of sweeping through Cyclopean corridors of stone, and up and down gigantic inclined planes of the same monstrous masonry. There were no stairs anywhere, nor was any passageway less than thirty feet wide. Some of the structures through which I floated must have towered in the sky for thousands of feet.

  There were multiple levels of black vaults below, and never-opened trap-doors, sealed down with metal bands and holding dim suggestions of some special peril.

  I seemed to be a prisoner, and horror hung broodingly over everything I saw. I felt that the mocking curvilinear hieroglyphs on the walls would blast my soul with their messag
e were I not guarded by a merciful ignorance.

  Still later my dreams included vistas from the great round windows, and from the titanic flat roof, with its curious gardens, wide barren area, and high, scalloped parapet of stone, to which the topmost of the inclined planes led.

  There were, almost endless leagues of giant buildings, each in its garden, and ranged along paved roads fully 200 feet wide. They differed greatly in aspect, but few were less than 500 feet square or a thousand feet high. Many seemed so limitless that they must have had a frontage of several thousand feet, while some shot up to mountainous altitudes in the grey, steamy heavens.

  They seemed to be mainly of stone or concrete, and most of them embodied the oddly curvilinear type of masonry noticeable in the building that held me. Roofs were flat and garden-covered, and tended to have scalloped parapets. Sometimes there were terraces and higher levels, and wide, cleared spaces amidst the gardens. The great roads held hints of motion, but in the earlier visions I could not resolve this impression into details.

  In certain places I beheld enormous dark cylindrical towers which climbed far above any of the other structures. These appeared to be of a totally unique nature and shewed signs of prodigious age and dilapidation. They were built of a bizarre type of square-cut basalt masonry, and tapered slightly toward their rounded tops. Nowhere in any of them could the least traces of windows or other apertures save huge doors be found. I noticed also some lower buildings--all crumbling with the weathering of aeons--which resembled these dark, cylindrical towers in basic architecture. Around all these aberrant piles of square-cut masonry there hovered an inexplicable aura of menace and concentrated fear, like that bred by the sealed trap-doors.

  The omnipresent gardens were almost terrifying in their strangeness, with bizarre and unfamiliar forms of vegetation nodding over broad paths lined with curiously carven monoliths. Abnormally vast fern-like growths predominated--some green, and some of a ghastly, fungoid pallor.
