"So you think that I am in need of out-door exercise?"
"Exactly."
"And that my experience was illusory, the result of vertigo, or some temporary calenture of the brain?"
"To be plain with you, yes."
"But I asked you a while ago if specters or phantoms ever leave tangible evidence of their presence." The Professor's eyes dilated in interrogation. I continued: "Well, this one did. After I had followed him out, I found on the table a long, white hair, which I still have," and producing the little coil from my pocket-book, I handed it to him. He examined it curiously, eyed me furtively, and handed it back with the cautious remark:
"I think you had better commence your exercise at once."
CHAPTER III.
A SECOND INTERVIEW WITH THE MYSTERIOUS VISITOR.
It is not pleasant to have one's mental responsibility brought in question, and the result of my interview with Professor Chickering was, to put it mildly, unsatisfactory. Not that he had exactly questioned my sanity, but it was all too evident that he was disposed to accept my statement of a plain matter-of-fact occurrence with a too liberal modicum of salt. I say "matter-of-fact occurrence" in full knowledge of the truth that I myself had at first regarded the whole transaction as a fantasia or flight of mind, the result of extreme nervous tension; but in the interval succeeding I had abundant opportunity to correlate my thoughts, and to bring some sort of order out of the mental and physical chaos of that strange, eventful night. True, the preliminary events leading up to it were extraordinary; the dismal weather, the depression of body and spirit under which I labored, the wild whirl of thought keeping pace with the elements—in short, a general concatenation of events that seemed to be ordered especially for the introduction of some abnormal visitor—the night would indeed have been incomplete without a ghost! But was it a ghost? There was nothing ghostly about my visitor, except the manner of his entrance and exit. In other respects, he seemed substantial enough. He was, in his manners, courteous and polished as a Chesterfield; learned as a savant in his conversation; human in his thoughtful regard of my fears and misgivings; but that tremendous forehead, with its crown of silver hair, the long, translucent beard of pearly whiteness, and above all the astounding facility with which he read my hidden thoughts—these were not natural.
The Professor had been patient with me—I had a right to expect that; he was entertaining to the extent of reading such excerpts as he had with him on the subject of hallucinations and their supposed causes, but had he not spoiled all by assigning me at last to a place with the questionable, unbalanced characters he had cited? I thought so, and the reflection provoked me; and this thought grew upon me until I came to regard his stories and attendant theories as so much literary trash.
My own reflections had been sober and deliberate, and had led me to seek a rational explanation of the unusual phenomena. I had gone to Professor Chickering for a certain measure of sympathy, and what was more to the point, to secure his suggestions and assistance in the further unraveling of a profound mystery that might contain a secret of untold use to humanity. Repulsed by the mode in which my confidence had been received, I decided to do what I should have done from the outset—to keep my own counsel, and to follow alone the investigation to the end, no matter what the result might be. I could not forget or ignore the silver hair I had so religiously preserved. That was genuine; it was as tangible, as real, as convincing a witness as would have been the entire head of my singular visitant, whatever might be his nature.
I began to feel at ease the moment my course was decided, and the feeling was at once renewed within me that the gray head would come again, and by degrees that expectation ripened into a desire, only intensified as the days sped by. The weeks passed into months; summer came and went; autumn was fast fading, but the mysterious unknown did not appear. A curious fancy led me now to regard him as my friend, for the mixed and indefinite feelings I felt at first towards him had almost unaccountably been changed to those of sincere regard. He was not always in my thoughts, for I had abundant occupation at all times to keep both brain and hands busy, but there were few evenings in which I did not, just before retiring, give myself up for a brief period to quiet communion with my own thoughts, and I must confess at such times the unknown occupied the larger share of attention. The constant contemplation of any theme begets a feeling of familiarity or acquaintance with the same, and if that subject be an individual, as in the present instance, such contemplation lessens the liability to surprise from any unexpected development. In fact, I not only anticipated a visit, but courted it. The old Latin maxim that I had played with, "Never less alone than when alone" had domiciled itself within my brain as a permanent lodger—a conviction, a feeling rather than a thought defined, and I had but little difficulty in associating an easy-chair which I had come to place in a certain position for my expected visitor, with his presence.
Indian summer had passed, and the fall was nearly gone when for some inexplicable reason the number seven began to haunt me. What had I to do with seven, or seven with me? When I sat down at night this persistent number mixed itself in my thoughts, to my intense annoyance. Bother take the mystic numeral! What was I to do with seven? I found myself asking this question audibly one evening, when it suddenly occurred to me that I would refer to the date of my friend's visit. I kept no journal, but reference to a record of some business transactions that I had associated with that event showed that it took place on November seventh. That settled the importunate seven! I should look for whomever he was on the first anniversary of his visit, which was the seventh, now close at hand. The instant I had reached this conclusion the number left me, and troubled me no more.
November third had passed, the fourth, and the fifth had come, when a stubborn, protesting notion entered my mind that I was yielding to a superstitious idea, and that it was time to control my vacillating will. Accordingly on this day I sent word to a friend that, if agreeable to him, I would call on him on the evening of the seventh for a short social chat, but as I expected to be engaged until later than usual, would he excuse me if I did not reach his apartments until ten? The request was singular, but as I was now accounted somewhat odd, it excited no comment, and the answer was returned, requesting me to come. The seventh of November came at last. I was nervous during the day, which seemed to drag tediously, and several times it was remarked of me that I seemed abstracted and ill at ease, but I held my peace. Night came cold and clear, and the stars shone brighter than usual, I thought. It was a sharp contrast to the night of a year ago. I took an early supper, for which I had no appetite, after which I strolled aimlessly about the streets, revolving how I should put in the time till ten o'clock, when I was to call upon my friend. I decided to go to the theater, and to the theater I went. The play was spectacular, "Aladdin; or, The Wonderful Lamp." The entertainment, to me, was a flat failure, for I was busy with my thoughts, and it was not long until my thoughts were busy with me, and I found myself attempting to answer a series of questions that finally became embarrassing. "Why did you make an appointment for ten o'clock instead of eight, if you wished to keep away from your apartments?" I hadn't thought of that before; it was stupid to a degree, if not ill-mannered, and I frankly admitted as much. "Why did you make an appointment at all, in the face of the fact that you not only expected a visitor, but were anxious to meet him?" This was easily answered: because I did not wish to yield to what struck me as superstition. "But do you expect to extend your call until morning?" Well, no, I hadn't thought or arranged to do so. "Well, then, what is to prevent your expected
