d 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.

Oppressed, as I certainly was, upon the occurrence of this second and
most extraordinary coincidence, by a thousand conflicting sensations,
in which wonder and extreme terror were predominant, I still retained
sufficient presence of mind to avoid exciting, by any observation, the
sensitive nervousness of my companion. I was by no means certain that
he had noticed the sounds in question; although, assuredly, a strange
alteration had, during the last few minutes, taken place in his
demeanor. From a position fronting my own, he had gradually brought
round his chair, so as to sit with his face to the door of the
chamber; and thus I could but partially perceive his features,
although I saw that his lips trembled as if he were murmuring
inaudibly. His head had dropped upon his breast--yet I knew that he
was not asleep, from the wide and rigid opening of the eye as I caught
a glance of it in profile. The motion of his body, too, was at
variance with this idea--for he rocked from side to side with a gentle
yet constant and uniform sway. Having rapidly taken notice of all
this, I resumed the narrative of Sir Launcelot, which thus
proceeded:--

"And now the champion, having escaped from the terrible fury of the
dragon, bethinking himself of the brazen shield, and of the breaking
up of the enchantment which was upon it, removed the carcass from out
of the way before him, and approached valorously over the silver
pavement of the castle to where the shield was upon the wall; which in
sooth tarried not for his full coming, but fell down at his feet upon
the silver floor, with a mighty, great and terrible ringing sound."

No sooner had these syllables passed my lips, than--as if a shield of
brass had indeed, at the moment, fallen heavily upon a floor of
silver--I became aware of a distinct, hollow, metallic and clangorous,
yet apparently muffled reverberation. Completely unnerved, I leaped to
my feet; but the measured rocking movement of Usher was undisturbed. I
rushed to the chair in which he sat. His eye
