ugal, 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 rece
