, and thence along
the Muskakituck, through Jennings and Ripley counties to Lawrenceville,
and you leave the rough and hilly portion of Indiana, to the right. Much
of the country we have denominated hilly is rich, fertile land, even to
the summits of the hills. On all the streams are strips of rich alluvion
of exhaustless fertility. The interior, on the two White rivers and
tributaries, is moderately undulating, tolerably rich soil, and much of
it heavily timbered with oaks of various species, poplar, beech, sugar
tree, walnuts, hickory, elm, and other varieties common to the West.
There is much level, table land, between the streams. Along the Wabash,
below Terre Haute, is an undulating surface, diversified with forest and
prairie, with a soil of middling quality, interspersed with some very
rich tracts. Along the Wabash and its tributaries above Terre Haute, the
land in general is first rate,--a large proportion forest, interspersed
with beautiful prairies. The timber consists of oaks of various species,
poplar, ash, walnut, cherry, elm, sugar tree, buckeye, hickory, some
beech, sassafras, lime, honey locust, with some cotton wood, sycamore,
hackberry and mulberry on the bottom lands. The undergrowth is spice
bush, hazel, plum, crab apple, hawthorn and vines. Along the northern
part of the State are extensive prairies and tracts of barrens, with
groves of various kinds of timber and skirts of burr oak. Towards lake
Michigan, and along the Kankakee and St. Joseph rivers, are lakes,
swamps and marshes.

_Rivers._--The Ohio meanders along the southeastern and southern parts
of the State for 350 miles. The east and west forks of White river, and
their tributaries, water the interior counties for 100 miles in extent.
They are both navigable streams for flat boats during the spring and
autumn floods. The Wabash river has several heads, which interlock with
the waters of the St. Joseph and St. Mary's, which form the Maumee of
lake Erie. It runs a south-westwardly course across the State to Warren
county,--thence southwardly to Vigo county, where it becomes the
boundary between Indiana and Illinois, along which it meanders to the
Ohio, which it enters 12 miles above Shawneetown. The St. Joseph of lake
Michigan, already noticed under the State of Michigan, makes a curve
into Elkhart and St. Joseph counties, forming what is called the _South
Bend_. The Kankakee, which is the longest branch of Illinois river,
rises in Indiana, n
