d miles) in twenty-two hours and a half--
much the swiftest passage I have ever made over that piece of water.

The next morning I came on with the four o'clock watch, and saw Ritchie
successfully run half a dozen crossings in a fog, using for his guidance
the marked chart devised and patented by Bixby and himself. This
sufficiently evidenced the great value of the chart.

By and by, when the fog began to clear off, I noticed that the
reflection of a tree in the smooth water of an overflowed bank, six
hundred yards away, was stronger and blacker than the ghostly tree
itself. The faint spectral trees, dimly glimpsed through the shredding
fog, were very pretty things to see.

We had a heavy thunder-storm at Natchez, another at Vicksburg, and still
another about fifty miles below Memphis. They had an old-fashioned
energy which had long been unfamiliar to me. This third storm was
accompanied by a raging wind. We tied up to the bank when we saw the
tempest coming, and everybody left the pilot-house but me. The wind bent
the young trees down, exposing the pale underside of the leaves; and
gust after gust followed, in quick succession, thrashing the branches
violently up and down, and to this side and that, and creating swift
waves of alternating green and white according to the side of the leaf
that was exposed, and these waves raced after each other as do their
kind over a wind-tossed field of oats. No color that was visible
anywhere was quite natural--all tints were charged with a leaden tinge
from the solid cloud-bank overhead. The river was leaden; all distances
the same; and even the far-reaching ranks of combing white-caps were
dully shaded by the dark, rich atmosphere through which their swarming
legions marched. The thunder-peals were constant and deafening;
explosion followed explosion with but inconsequential intervals between,
and the reports grew steadily sharper and higher-keyed, and more trying
to the ear; the lightning was as diligent as the thunder, and produced
effects which enchanted the eye and sent electric ecstasies of mixed
delight and apprehension shivering along every nerve in the body in
unintermittent procession. The rain poured down in amazing volume; the
ear-splitting thunder-peals broke nearer and nearer; the wind increased
in fury and began to wrench off boughs and tree-tops and send them
sailing away through space; the pilot-house fell to rocking and
straining and cracking and surging, and I
