His attitude was one of such expectation and watchfulness that I
stopped a moment, wondering at it.

I resumed my downward way, and stepping out upon the level of the
railroad, and drawing nearer to him, saw that he was a dark, sallow
man, with a dark beard and rather heavy eyebrows. His post was in
as solitary and dismal a place as ever I saw. On either side, a
dripping-wet wall of jagged stone, excluding all view but a strip
of sky; the perspective one way only a crooked prolongation of this
great dungeon; the shorter perspective in the other direction
terminating in a gloomy red light, and the gloomier entrance to a
black tunnel, in whose massive architecture there was a barbarous,
depressing, and forbidding air. So little sunlight ever found its
way to this spot, that it had an earthy, deadly smell; and so much
cold wind rushed through it, that it struck chill to me, as if I
had left the natural world.

Before he stirred, I was near enough to him to have touched him.
Not even then removing his eyes from mine, he stepped back one
step, and lifted his hand.

This was a lonesome post to occupy (I said), and it had riveted my
attention when I looked down from up yonder. A visitor was a
rarity, I should suppose; not an unwelcome rarity, I hoped? In me,
he merely saw a man who had been shut up within narrow limits all
his life, and who, being at last set free, had a newly-awakened
interest in these great works. To such purpose I spoke to him; but
I am far from sure of the terms I used; for, besides that I am not
happy in opening any conversation, there was something in the man
that daunted me.
