left to glower at heaven in impotent rage for evermore!

Finally we stood in a level, narrow valley (a valley that had been
created by the terrific march of some old time irruption) and on either
hand towered the two steep peaks of Vesuvius. The one we had to climb
--the one that contains the active volcano--seemed about eight hundred or
one thousand feet high, and looked almost too straight-up-and-down for
any man to climb, and certainly no mule could climb it with a man on his
back. Four of these native pirates will carry you to the top in a sedan
chair, if you wish it, but suppose they were to slip and let you fall,
--is it likely that you would ever stop rolling? Not this side of
eternity, perhaps. We left the mules, sharpened our finger-nails, and
began the ascent I have been writing about so long, at twenty minutes to
six in the morning. The path led straight up a rugged sweep of loose
chunks of pumice-stone, and for about every two steps forward we took, we
slid back one. It was so excessively steep that we had to stop, every
fifty or sixty steps, and rest a moment. To see our comrades, we had to
look very nearly straight up at those above us, and very nearly straight
down at those below. We stood on the summit at last--it had taken an
hour and fifteen minutes to make the trip.

What we saw there was simply a circular crater--a circular ditch, if you
please--about two hundred feet deep, and four or five hundred feet wide,
whose inner wall was about half a mile in circumference. In the centre
of the great circus ring thus formed, was a torn and ragged upheaval a
hundred feet high, all snowed over with a sulphur crust of many and many
a brilliant and beautiful color, and the ditch inclosed this like the
moat of a castle, or surrounded it as a little river does a little
island, if the simile is better. The sulphur coating of that island was
gaudy in the extreme--all mingled together in the richest confusion were
