Champaign county is located close to the center of Illinois. The
land is flat, and the soil rich. The county lies in the heart of what was once called the
"Grand Prairie". Workable seams of bituminous coal underlie the surface, but overlying quick sands interfere with
their operation. The Sangamon and Kaskaskia Rivers have their sources in this region, and several railroads cross
the county. The soil is a black muck under laid by a yellow clay. Urbana (with a population of 5,708 in 1900) is the
county seat. Other important points in the county are Champaign (9,000), Tolono (1,000), and Rantoul (1,200).
Champaign and Urbana adjoin each other, and the grounds of the Illinois State University extend into each
corporation, being largely situated in Champaign. Large drifted masses of Niagara limestone are found, interspersed
with coal measure limestone and sandstone. Alternating beds of clay, gravel and quicksand of the drift formation are
found beneath the subsoil to the depth of 150 to 300 feet.
