THE 'BODY OF THE NATION'
BUT the basin of the Mississippi is the BODY OF THE NATION. All the
other parts are but members, important in themselves, yet more important
in their relations to this. Exclusive of the Lake basin and of 300,000
square miles in Texas and New Mexico, which in many aspects form a part
of it, this basin contains about 1,250,000 square miles. In extent it
is the second great valley of the world, being exceeded only by that of
the Amazon. The valley of the frozen Obi approaches it in extent; that
of La Plata comes next in space, and probably in habitable capacity,
having about eight-ninths of its area; then comes that of the Yenisei,
with about seven-ninths; the Lena, Amoor, Hoang-ho, Yang-tse-kiang, and
Nile, five-ninths; the Ganges, less than one-half; the Indus, less than
one-third; the Euphrates, one-fifth; the Rhine, one-fifteenth. It
exceeds in extent the whole of Europe, exclusive of Russia, Norway, and
Sweden. IT WOULD CONTAIN AUSTRIA FOUR TIMES, GERMANY OR SPAIN FIVE
TIMES, FRANCE SIX TIMES, THE BRITISH ISLANDS OR ITALY TEN TIMES.
Conceptions formed from the river-basins of Western Europe are rudely
shocked when we consider the extent of the valley of the Mississippi;
nor are those formed from the sterile basins of the great rivers of
Siberia, the lofty plateaus of Central Asia, or the mighty sweep of the
swampy Amazon more adequate. Latitude, elevation, and rainfall all
combine to render every part of the Mississippi Valley capable of
supporting a dense population. AS A DWELLING-PLACE FOR CIVILIZED MAN IT
IS BY FAR THE FIRST UPON OUR GLOBE.

Chapter 1 The River and Its History
THE Mississippi is well worth reading about. It is not a commonplace
river, but on the contrary is in all ways remarkable. Considering the
Missouri its main branch, it is the longest river in the world - four
thousand three hundred miles. It seems safe to say that it is also the
crookedest river in the world, since in one part of its journey it uses
up one thousand three hundred miles to cover the same ground that the
crow would fly over in six hundred and seventy-five. It discharges three
times as much water as the St. Lawrence, twenty-five times as much as
the Rhine, and three hundred and thirty-eight times as much as the
Thames. No other river has so vast a drainage-basin: it draws its water
supply from twenty-eight States and Territories; from Delaware, on the
Atlantic seaboard, and from all the country between that and Idaho on
the Pacific slope - a spread of forty-five degrees of longitude. The
Mississippi receives and carries to the Gulf water from fifty-four
subordinate rivers that are navigable by steamboats, and from some
hundreds that are navigable by flats and keels. The area of its
drainage-basin is as great as the combined areas of England, Wales,
Scotland, Ireland, France, Spain, Portugal, Germany, Austria, Italy, and
Turkey; and almost all this wide region is fertile; the Mississippi
valley, proper, is exceptionally so.
It is a remarkable river in this: that instead of widening toward its
mouth, it grows narrower; grows narrower and deeper. From the junction
of the Ohio to a point half way down to the sea, the width averages a
mile in high water: thence to the sea the width steadily diminishes,
until, at the 'Passes,' above the mouth, it is but little over half a
mile. At the junction of the Ohio the Mississippi's depth is eighty-
seven feet; the depth increases gradually, reaching one hundred and
twenty-nine just above the mouth.
The difference in rise and fall is also remarkable - not in the upper,
but in the lower river. The rise is tolerably uniform down to Natchez
(three hundred and sixty miles above the mouth) - about fifty feet. But
at Bayou La Fourche the river rises only twenty-four feet; at New
Orleans only fifteen, and just above the mouth only two and one half.
An article in the New Orleans 'Times-Democrat,' based upon reports of
able engineers, states that the river annually empties four hundred and
six million tons of mud into the Gulf of Mexico - which brings to mind
Captain Marryat's rude name for the Mississippi - 'the Great Sewer.' This
mud, solidified, would make a mass a mile square and two hundred and
forty-one feet high.
The mud deposit gradually extends the land - but only gradually; it has
extended it not quite a third of a mile in the two hundred years which
have elapsed since the river took its place in history. The belief of
the scientific people is, that the mouth used to be at Baton Rouge,
where the hills cease, and that the two hundred miles of land between
there and the Gulf was built by the river. This gives us the age of that
piece of country, without any trouble at all - one hundred and twenty
thousand years. Yet it is much the youthfullest batch of country that
lies around there anywhere.
The Mississippi is remarkable in still another way - its disposition to
make prodigious jumps by cutting through narrow necks of land, and thus
straightening and shortening itself. More than once it has shortened
itself thirty miles at a single jump! These cut-offs have had curious
effects: they have thrown several river towns out into the rural
districts, and built up sand bars and forests in front of them. The town
of Delta used to be three miles below Vicksburg: a recent cutoff has
radically changed the position, and Delta is now TWO MILES ABOVE
Vicksburg.
Both of these river towns have been retired to the country by that cut-
off. A cut-off plays havoc with boundary lines and jurisdictions: for
instance, a man is living in the State of Mississippi to-day, a cut-off
occurs to-night, and to-morrow the man finds himself and his land over
on the other side of the river, within the boundaries and subject to the
laws of the State of Louisiana!
