sippi--'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! Such a thing, happening
in the upper river in the old times, could have transferred a slave from
Missouri to Illinois and made a free man of him.

The Mississippi does not alter its locality by cut-offs alone: it is
always changing its habitat BODILY--is always moving bodily SIDEWISE.
At Hard Times, La., the river is two miles west of the region it used to
occupy. As a result, the original SITE of that settlement is not now in
Louisiana at all, but on the other side of the river, in the State of
Mississippi. NEARLY THE WHOLE OF THAT ONE THOUSAND THREE HUNDRED MILES
OF OLD MISSISSIPPI RIVER WHICH LA SALLE FLOATED DOWN IN HIS CANOES, TWO
HUNDRED YEARS AGO, IS GOOD SOLID DRY GROUND NOW. The river lies to the
right of it, in places, and to the left of it in other places.
