The most beautiful tributary of the Mississippi is the Ohio, the Belle rivière of the early French settlers, the only large river it receives from the east. No stream rolls for the same distance so uniformly and peacefully; its banks are adorned with the largest sycamores, its waters clear, and studded with islands covered with the finest trees. All the other great tributaries flow from the west: its confluence with the Missouri, which enters it like a conqueror, and carries its white waves to the opposite shore, presenting one of the most extraordinary views in the world. The country around these vast watercourses is of the most varied description, alternately exhibiting wild rice-lakes and swamps, lime-stone bluffs and craggy hills, deep pine forests and beautiful prairies, the prairies showing an almost perfect level, in summer covered with a luxuriant growth of grass and flowers, without a tree or a bush, the only tenants of which are elks and buffaloes, bears and deer, and the savages that pursue them. The bluffs of the Mississippi are for the most part perpendicular masses of limestone, often shooting up into towers and pinnacles, presenting at a distance the aspect of the battlements and turrets of an ancient city. In the season of inundation, below the mouth of the Ohio, the river presents a very striking spectacle. It sweeps along in curves or sections of circles, from six to twelve miles in extent, measured from point to point, and not far from the medial width of a mile. On a calm spring morning, and under a bright sun, this sheet of water shines like a mass of burnished silver, its edges being distinctly marked by a magnificent outline of cotton-wood trees, at this time of the year of the brightest verdure, among which those brilliant birds of the country, the black and red bird, and the blue jay, flit to and fro, or wheel their flight over them, forming a scene which has all of grandeur or beauty that nature can furnish, to soothe or enrapture the beholder. The curvilinear course of the Mississippi is one of its most striking peculiarities. It meanders in uniform bends, which, in many instances, are described with a precision equal to that obtained by the point of a compass. The river sweeps round the half of a circle, and is then precipitated in a diagonal direction across its own channel, to another curve of the same regularity upon the opposite shore. Instead of calculating distances by miles or leagues, the boatmen and Indians estimate their progress by the number of bends which they have passed. This conformation, which distinguishes most of the streams of the Mississippi valley, must have transpired under the operation of some law; but hitherto no solution of the problem has been given which is quite satisfactory. Geological appearances indicate that this stream, like the Orinoco, had in former ages a much broader volume, though a shorter course; that, in fact, it once found its estuary not far below the present mouth of the Ohio; the alluvial country now stretching from thence to the south, near a thousand miles, being then an arm of the sea. “No thinking mind,” says Flint, “can contemplate this mighty and resistless wave, sweeping its proud course from point to point, curving round its bends through the dark forests, without a feeling of sublimity. The hundred shores, laved by its waters; the long course of its tributaries, some of which are already the abodes of cultivation, and others pursuing an immense course without a solitary dwelling of civilized man on their banks; the numerous tribes of savages that now roam on its borders; the affecting and imperishable traces of generations that are gone, leaving no other memorial of their existence, or materials for their history than their tombs, that rise at frequent intervals along its banks; the dim, but glorious anticipations of the future—these are subjects of contemplation that cannot but associate themselves with a view of this river.”
Though far inferior to these streams of the western world in point of length and volume, the Nile of the ancient continent may be placed at the head of remarkable rivers. One of its chief peculiarities is the solitary grandeur of its flow; for not a single affluent enters it from the junction of the Tacazze to the sea, a distance of 1500 miles—a circumstance without a parallel in the physical condition of rivers. Another of its striking features is its long course through a desert, dry, barren, and hideous, depositing by its annual inundation the richest soil on those portions of it which lie contiguous to its banks; and hence has originated the apt comparison of its career to the path of a good man amidst an evil generation. Egypt would be completely sterile were it not for the periodical overflow of its only stream, which both covers a large part of its surface with a layer of alluvion, and imparts to it the requisite moisture.
“Rich king of floods! o’erflows the swelling Nile—
——glad to quit
The joyless desert, down the Nubian rocks
From thund’ring steep to steep he pours his urn,
And Egypt joys beneath the spreading wave.”
It requires the river to attain a medium rise in order to benefit the country: too little, involving scarcity and famine; too much, compromising the safety of the people and their dwellings. Wilkinson calls a rise of 19 cubits, tolerable; 20, good; 21, sufficient; while a rise of 22 cubits is abundant enough to fill every canal, and a rise of 24 cubits would overwhelm and ruin the villages. A cubit is rather more than 21 inches; so that, in order fully to meet the wants of the country, a perpendicular rise of 38 feet is necessary. The Nile is also distinguished among rivers for the pleasant taste and salubrity of its waters when not in flood; properties highly extolled by the ancients, and acknowledged to belong to it by modern travelers. It is a common saying with the Egyptians, that if Mahomet had tasted of its stream, he would have sought a terrestrial immortality in order to enjoy it forever. The physical circumstances of the river easily account for the possession of this attribute. The air above is pure and serene. But little rain falls upon the country through which the greater part of its course is prosecuted, and no snow or hail. Hence there is little drainage into it from the surrounding land, and its waters are kept free from any noxious taint derived from earths and minerals, except from those in its immediate channel. The same property of being remarkably pure and salutary is ascribed by Herodotus to one of the Susianic rivers, of which alone, according to tradition, none but the kings of Persia drank.
“There Susa, by Choaspes’ amber stream,
The drink of none but kings.”
