, and trying to go to sleep; but the harder
I tried, the wider awake I grew. I got to feeling very lonely
in the dark, with no company but an undigested dinner.
My mind got a start by and by, and began to consider the
beginning of every subject which has ever been thought of;
but it never went further than the beginning; it was touch
and go; it fled from topic to topic with a frantic speed.
At the end of an hour my head was in a perfect whirl and I
was dead tired, fagged out.

The fatigue was so great that it presently began to make some
head against the nervous excitement; while imagining myself
wide awake, I would really doze into momentary unconsciousness,
and come suddenly out of it with a physical jerk which nearly
wrenched my joints apart--the delusion of the instant
being that I was tumbling backward over a precipice.
After I had fallen over eight or nine precipices and thus
found out that one half of my brain had been asleep eight
or nine times without the wide-awake, hard-working other
half suspecting it, the periodical unconsciousnesses
began to extend their spell gradually over more of my
brain-territory, and at last I sank into a drowse which
grew deeper and deeper and was doubtless just on the very
point of being a solid, blessed dreamless stupor, when--what was
that?

My dulled faculties dragged themselves partly back to life
and took a receptive attitude. Now out of an immense,
a limitless distance, came a something which grew and grew,
and approached, and presently was recognizable as a sound
--it had rather seemed to be a feeling, before. This sound
was a mile away, now--perhaps it was the murmur of a storm;
and now it was nearer--not a quarter of a mile away;
was it the muffled rasping and grinding of distant
machinery? No, it came still nearer; was it the measured
tramp of a marching troop? But it came nearer still,
and still nearer--and at last it was right in the room: it
was merely a mouse gnawing the woodwork. So I had held my
breath all that time for such a trifle.

Well, what was done could not be helped; I would go
to sleep at once and make up the lost time. That was
a thoughtless thought. Without intending it--hardly
knowing it--I fell to listening intently to that sound,
and even unconsciously counting the strokes of the mouse's
nutmeg-grater. Presently I was deriving exquisite suffering
from this employment, yet maybe I could have endured
it if the mouse had attended steadily
