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.

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 t
