II. By the Lower Louisiana, our author means only the Delta of the
Missisippi, or the drowned lands made by the overflowing of the river.
But we may more properly give {vi} that appellation to the whole
country, from the low and flat sea coast above described, to the
mountains, which begin about the latitude 35 deg., a little above the
river St. Francis; that is, five degrees of latitude, or three hundred
and fifty statute miles from the coast; which they reckon to be six
hundred and sixty miles up the Missisippi. About that latitude a
continued ridge of mountains runs westward from the Apalachean
mountains nigh to the banks of the Missisippi, which are thereabouts
very high, at what we have called the Chicasaw Cliffs. Opposite to
these on the west side of the Missisippi, the country is mountainous,
and continues to be so here and there, as far as we have any accounts
of it, westward to the mountains of New Mexico; which run in a chain
of continued ridges from north to south, and are reckoned to divide
that country from Louisiana, about 900 miles west from the Missisippi.

This is one entire level champaign country; the part of which that
lies west of the Missisippi is 900 miles (of sixty to a degree) by
300, and contains 270,000 square miles, as much as both France and
Spain put together. This country lies in the latitude of those
fruitful regions of Barbary, Syria, Persia, India, and the middle of
China, and is alone sufficient to supply the world with all the
products of North America. It is very fertile in every thing, both in
lands and metals, by all the accounts we have of it; and is watered by
several large navigable rivers, that spread over the whole country
from the Missisippi to New Mexico; besides several smaller rivers on
the coast west of the Missisippi, that fall into the bay of Mexico; of
which we have no good accounts, if it be not that Mr. Coxe tells us of
one, the river of the Cenis, which, he says, "is broad, deep, and
