450 ZZF^ ON THE MISSISSIPPI. We made Natchez (three hundred 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 Bkby and himself. This sufficiently evidenced the great value of the chart. By and by, when the fog began to dear 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 Yicksburg, 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 soo- cession, 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 colour 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 em the far-reaching ranks of combing white-caps were dully shaded hy the dark, rich atmosphere through which their swarming legions inarched. 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 pro- duced effects which enchanted the eye and sent electric ecstasies if mixed delight and apprehension shivering along every nerve in the body in unintermittenfr procession. The rain poured down in *.rn*mg volume; the ear-splitting thunder-peals broke nearer and nearer; the wind increased in fury and b«M$an to wrench off boughs and tree*
