“You must not—­you shall not behold this!” said I, shudderingly, to Usher, as I led him, with a gentle violence, from the window to a seat.  “These appearances, which bewilder you, are merely electrical phenomena not uncommon—­or it may be that they have their ghastly origin in the rank miasma of the tarn.  Let us close this casement;—­the air is chilling and dangerous to your frame.  Here is one of your favourite romances.  I will read, and you shall listen;—­and so we will pass away this terrible night together.”

The antique volume which I had taken up was the Mad Trist of Sir Launcelot Canning; but I had called it a favourite of Usher’s more in sad jest than in earnest; for, in truth, there is little in its uncouth and unimaginative prolixity which could have had interest for the lofty and spiritual ideality of my friend.  It was, however, the only book immediately at hand; and I indulged a vague hope that the excitement which now agitated the hypochondriac, might find relief (for the history of mental disorder is full of similar anomalies) even in the extremeness of the folly which I should read.  Could I have judged, indeed, by the wild overstrained air of vivacity with which he hearkened, or apparently hearkened, to the words of the tale, I might well have congratulated myself upon the success of my design.

I had arrived at that well-known portion of the story where Ethelred, the hero of the Trist, having sought in vain for peaceable admission into the dwelling of the hermit, proceeds to make good an entrance by force.  Here, it will be remembered, the words of the narrative run thus: 

“And Ethelred, who was by nature of a doughty heart, and who was now mighty withal, on account of the powerfulness of the wine which he had drunken, waited no longer to hold parley with the hermit, who, in sooth, was of an obstinate and maliceful turn, but, feeling the rain upon his shoulders, and fearing the rising of the tempest, uplifted his mace outright, and, with blows, made quickly room in the plankings of the door for his gauntleted hand; and now pulling therewith sturdily, he so cracked and ripped, and tore all asunder, that the noise of the dry and hollow-sounding wood alarmed and reverberated throughout the forest.”

At the termination of this sentence I started, and, for a moment, paused; for it appeared to me (although I at once concluded that my excited fancy had deceived me)—­it appeared to me that, from some very remote portion of the mansion, there came, indistinctly, to my ears, what might have been, in its exact similarity of character, the echo (but a stifled and dull one certainly) of the very cracking and ripping sound which Sir Launcelot had so particularly described.  It was, beyond doubt, the coincidence alone which had arrested my attention; for, amid the rattling of the sashes of the casements, and the ordinary commingled noises of the still increasing storm, the sound, in itself, had nothing, surely, which should have interested or disturbed me.  I continued the story:
