I well remember that suggestions arising from this ballad led us into a train of thought wherein there became manifest an opinion of Usher's which I mention not so much on account of its novelty, (for other men have thought thus,) as on account of the pertinacity with which he maintained it. This opinion, in its general form, was that of the sentience of all vegetable things. But, in his disordered fancy, the idea had assumed a more daring character, and trespassed, under certain conditions, upon the kingdom of inorganization. I lack words to express the full extent, or the earnest abandon of his persuasion. The belief, however, was connected (as I have previously hinted) with the gray stones of the home of his forefathers. The conditions of the sentience had been here, he imagined, fulfilled in the method of collocation of these stones --in the order of their arrangement, as well as in that of the many fungi which overspread them, and of the decayed trees which stood around --above all, in the long undisturbed endurance of this arrangement, and in its reduplication in the still waters of the tarn. Its evidence --the evidence of the sentience --was to be seen, he said, (and I here started as he spoke,) in the gradual yet certain condensation of an atmosphere of their own about the waters and the walls. The result was discoverable, he added, in that silent, yet importunate and terrible influence which for centuries had moulded the destinies of his family, and which made him what I now saw him --what he was. Such opinions need no comment, and I will make none.

Our books --the books which, for years, had formed no small portion of the mental existence of the invalid --were, as might be supposed, in strict keeping with this character of phantasm. We pored together over such works as the Ververt et Chartreuse of Gresset; the Belphegor of Machiavelli; the Heaven and Hell of Swedenborg; the Subterranean Voyage of Nicholas Klimm by Holberg; the Chiromancy of Robert Flud, of Jean D'Indagine, and of De la Chambre; the Journey into the Blue Distance of Tieck; and the City of the Sun of Campanella. One favourite volume was a small octavo edition of the Directorium Inquisitorum, by the Dominican Eymeric de Gironne; and there were passages in Pomponius Mela, about the old African Satyrs and AEgipans, over which Usher would sit dreaming for hours. His chief delight, however, was found in the perusal of an exceedingly rare and curious book in quarto Gothic --the manual of a forgotten church --the Vigilae Mortuorum secundum Chorum Ecclesiae Maguntinae.

I could not help thinking of the wild ritual of this work, and of its probable influence upon the hypochondriac, when, one evening, having informed me abruptly that the lady Madeline was no more, he stated his intention of preserving her corpse for a fortnight, (previously to its final interment,) in one of the numerous vaults within the main walls of the building. The worldly reason, however, assigned for this singular proceeding, was one which I did not feel at liberty to dispute. The brother had been led to his resolution (so he told me) by consideration of the unusual character of the malady of the deceased, of certain obtrusive and eager inquiries on the part of her medical men, and of the remote and exposed situation of the burial-ground of the family. I will not deny that when I called to mind the sinister countenance of the person whom I met upon the stair case, on the day of my arrival at the house, I had no desire to oppose what I regarded as at best but a harmless, and by no means an unnatural, precaution.

At the request of Usher, I personally aided him in the arrangements for the temporary entombment. The body having been encoffined, we two alone bore it to its rest. The vault in which we placed it (and which had been so long unopened that our torches, half smothered in its oppressive atmosphere, gave us little opportunity for investigation) was small, damp, and entirely without means of admission for light; lying, at great depth, immediately beneath that portion of the building in which was my own sleeping apartment. It had been used, apparently, in remote feudal times, for the worst purposes of a donjon-keep, and, in later days, as a place of deposit for powder, or some other highly combustible substance, as a portion of its floor, and the whole interior of a long archway through which we reached it, were carefully sheathed with copper. The door, of massive iron, had been, also, similarly protected. Its immense weight caused an unusually sharp grating sound, as it moved upon its hinges.
