"...it appeared to me that, from some 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 Lancelot 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: ‘But the good champion Ethelred, now entering within the door, was sore enraged and amazed to perceive no signal of the maliceful hermit; but, in the stead thereof, a dragon of scaly and prodigious demeanor, and of fiery tongue, which state in guard before a palace of gold, with a floor of silver; and upon the wall there hung a shield of shining brass with this legend enwritten,
Who entereth herein, a conqueror hath bin;
Who slayeth the dragon, the shield he shall win.
And Ethelred uplifted his mace, and struck upon the head of the dragon, which fell before him, and gave up his pesty breath, with a shriek so horrid and harsh, and withal so piercing, that Ethelred had fain to close his ears with his hands against the dreadful noise of it, the like whereof was never before heard.'
Here again I paused abruptly, and now with a feeling of wild amazement...for there could be no doubt whatever that, in this instance, I did actually hear (although from what direction it proceeded I found it impossible to say) a low and apparently distant, but harsh, protracted, and most unusual screaming or grating sound...the exact counterpart of what my fancy had already conjured up for the dragon’s unnatural shriek as described by the romancer."
