monstrous things burst out; the air grew filled with them: larvae so bloodless and so hideous that I can in no way describe them except to remind the reader of the swarming life which the solar microscope brings before his eyes in a drop of water,—things transparent, supple, agile, chasing each other, devouring each, other; forms like nought ever beheld by the naked eye. As the shapes were without symmetry, so their movements were without order. In their very vagrancies there was no sport; they came round me and round, thicker and faster and swifter, swarming over my head, crawling over my right arm, which was outstretched in involuntary command against all evil beings. Sometimes I felt myself touched, but not by them; invisible hands touched me. Once I felt the clutch as of cold, soft fingers at my throat. I was still equally conscious that if I gave way to fear I should be in bodily peril; and I concentred all my faculties in the single focus of resisting stubborn will. And I turned my sight from the Shadow; above all, from those strange serpent eyes,—eyes that had now become distinctly visible. For there, though in nought else around me, I was aware that there was a WILL, and a will of intense, creative, working evil, which might crush down my own.

The pale atmosphere in the room began now to redden as if in the air of some near conflagration. The larvæ grew lurid as things that live in fire. Again the room vibrated; again were heard the three measured knocks; and again all things were swallowed up in the darkness of the dark Shadow, as if out of that darkness all had come, into that darkness all returned.

As the gloom receded, the Shadow was wholly gone. Slowly, as it had been withdrawn, the flame grew again into the candles on the table, again into the fuel in the grate. The whole room came once more calmly, healthfully into sight.

The two doors were still closed, the door communicating with the servant's room still locked. In the corner of the wall, into which he had so convulsively niched himself, lay the dog. I called to him,—no movement; I approached,—the animal was dead: his eyes protruded; his tongue out of his mouth; the froth gathered round his jaws. I took him in my arms; I brought him to the fire. I felt acute grief for the loss of my poor favorite,—acute self-reproach; I accused myself of his death; I imagined he had died of fright. But what was my surprise on finding that his neck was actually broken. Had this been done in the dark? Must it not have been by a hand human as mine; must there not have been a human agency all the while in that room? Good cause to suspect it. I cannot tell. I cannot do more than state the fact fairly; the reader may draw his own inference.

Another surprising circumstance,—my watch was restored to the table from which it had been so mysteriously withdrawn; but it had stopped at the very moment it was so withdrawn, nor, despite all the skill of the watchmaker, has it ever gone since,—that is, it will go in a strange, erratic way for a few hours, and then come to a dead stop; it is worthless.

Nothing more chanced for the rest of the night. Nor, indeed, had I long to wait before the dawn broke. Nor till it was broad daylight did I quit the haunted house. Before I did so, I revisited the little blind room in which my servant and myself had been for a time imprisoned. I had a strong impression—for which I could not account—that from that room had originated the mechanism of the phenomena, if I may use the term, which had been experienced in my chamber. And though I entered it now in the clear day, with the sun peering through the filmy window, I still felt, as I stood on its floors, the creep of the horror which I had first there experienced the night before, and which had been so aggravated by what had passed in my own chamber. I could not, indeed, bear to stay more than half a minute within those walls. I descended the stairs, and again I heard the footfall before me; and when I opened the street door, I thought I could distinguish a very low laugh. I gained my own home, expecting to find my runaway servant there; but he had not presented himself, nor did I hear more of him for three days, when I received a letter from him, dated from Liverpool to this effect:—

"HONORED SIR,—I humbly entreat your pardon, though I can scarcely hope that you will think that I deserve it, unless—which Heaven forbid!—you saw what I did. I feel that it will be years before I can recover myself; and as to being fit for service, it is out of the question. I am therefore going to my brother-in-law at Melbourne. The ship sails to-morrow. Perhaps the long voyage may set me up. I do nothing now but start and tremble, and fancy IT is behind me. I humbly beg you, honored sir, to order my clothes, and whatever wages are due to me, to be sent to my mother's, at Walworth,—John knows her address."

The letter ended with additional apologies, somewhat incoherent, and explanatory details as to effects that had been under the writer's charge. This flight may perhaps warrant a suspicion that the man wished to go to Australia, and had been somehow or other fraudulently mixed up with the events of the night. I say nothing in refutation of that conjecture; rather, I suggest it as one that would seem to many persons the most probable solution of improbable occurrences. My belief in my own theory remained unshaken. I returned in the evening to the house, to bring away in a hack cab the things I had left there, with my poor dog's body. In this task I was not disturbed, nor did any incident worth note befall me, except that still, on ascending and descending the stairs, I heard the same footfall in advance. On leaving the house, I went to Mr. J——'s. He was at home. I returned him the keys, told him that my curiosity was sufficiently gratified, and was about to relate quickly what had passed, when he stopped me, and said, though with much politeness, that he had no longer any interest in a mystery which none had ever solved.

I determined at least to tell him of the two letters I had read, as well as of the extraordinary manner in which they had disappeared; and I then inquired if he thought they had been addressed to the woman who had died in the house, and if there were anything in her early history which could possibly confirm the dark suspicions to which the letters gave rise. Mr. J—— seemed startled, and, after musing a few moments, answered, "I am but little acquainted with the woman's earlier history, except as I before told you, that her family were known to mine. But you revive some vague reminiscences to her prejudice. I will make inquiries, and inform you of their result. Still, even if we could admit the popular superstition that a person who had been either the perpetrator or the victim of dark crimes in life could revisit, as a restless spirit, the scene in which those crimes had been committed, I should observe that the house was infested by strange sights and sounds before the old woman died—you smile—what would you say?"

"I would say this, that I am convinced, if we could get to the bottom of these mysteries, we should find a living human agency."

"What! you believe it is all an imposture? For what object?"

"Not an imposture in the ordinary sense of the word. If suddenly I were to sink into a deep sleep, from which you could not awake me, but in that sleep could answer questions with an accuracy which I could not pretend to when awake,—tell you what money you had in your pocket, nay, describe your very thoughts,—it is not necessarily an imposture, any more than it is necessarily supernatural. I should be, unconsciously to myself, under a mesmeric influence, conveyed to me from a distance by a human being who had acquired power over me by previous rapport."

"But if a mesmerizer could so affect another living being, can you
