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 on which he sat. His eyes were bent fixedly before
him, and throughout his whole countenance there reigned a stony
rigidity. But, as I placed my hand upon his shoulder, there came a
strong shudder over his whole person; a sickly smile quivered about his
lips; and I saw that he spoke in a low, hurried, and gibbering murmur,
as if unconscious of my presence. Bending closely over him, I at length
drank in the hideous import of his words.

"Not hear it?--yes, I hear it, and _have_ heard it.
