ced all the State north-west of Rock
river, but recently divided into three or four counties. Besides the
Mississippi, it has Fever river, Pekatonokee, Apple river, and Rush and
Plum creeks. A rich county, both for agricultural and mining purposes.
Timber scarce, and in groves; surface undulating,--in some places hilly;
well watered by streams and springs, and has good mill sites. Copper and
lead ore in abundance.

JOHNSON.--The Ohio on the south, Cash river and Big Bay creek,
and a series of lakes or ponds interior. A timbered country, tolerably
level; soil sandy, with considerable quantities of second rate land.

KNOX.--Watered by Henderson and Spoon rivers, and their
tributaries. The prairies large, moderately undulating, and first
quality of soil, with excellent timber along the water courses.

LASALLE.--Besides the Illinois river, which passes through it,
Fox river, Big and Little Vermillion, Crow, Au Sable, Indian, Mason,
Tomahawk, and other creeks, water this county. They generally run on a
bed of sand or lime rock, and have but little alluvial bottom lands.
Deficient in timber, but has an abundance of rich, undulating prairie,
beautiful groves, abundant water privileges, and extensive coal banks.

LAWRENCE.--The Wabash east, Fox river west, and Embarras and
Raccoon through it. An equal proportion of timber and prairie, some
excellent, other parts inferior,--and some bad, miry swamps, called
"_purgatories_."

MACON.--South-east portion, watered by the Kaskaskia and
tributaries; the middle and northern portions by the North Fork of
Sangamon, and the north-western part by Salt creek. The prairies large,
and in their interior, level and wet,--towards the timber, dry,
undulating and rich.

MADISON.--The Mississippi lies west; Cahokia and Silver creeks,
and Wood river, run through it. A part of this county lies in the
American bottom, and is a rich and level alluvion; but much of the
county is high, undulating, and proportionably divided into timber and
prairie. Well supplied with stone quarries and coal banks.

MACOUPEN.--The Macoupen creek and branches water its central
and western parts, the Cahokia the south-eastern, and the heads of Wood
river and Piasau, the south-western parts. A large proportion of the
county is excellent soil, well proportioned into timber and prairie, and
slightly undulating.

MARION.--Watered by the East Fork, and Crooked creek,
tributaries of Kaskaskia river, on its western, and
