West Virginia. The Ohio basin does not show a uniform slope towards
its centre downward in the direction of its major axis. It is undulating,
and often exhibits areas of considerable extent, with a northern slope
and drainage. In West Virginia, the Monongahela flows northward to
meet the Alleghany at Pittsburg. In the Second District, I find small
areas with a similar slope and drainage. Several of the smaller tributaries of the Muskingum river flow in a northerly direction. The principal
rivers in the District are the Muskingum, Scioto and Hocking, all flowing into the Ohio river. Between the Scioto and the Hocking are several
smaller streams, the Little Scioto, Pine creek, Symmes' creek, Indian
Guyandotte creek, Raccoon creek, Leading creek, and Shade river, all
emptying into the Ohio. Between the Hocking and Muskingum is the
Little Hocking. Above the Muskingum, the principal tributaries of the
Ohio are Duck creek, Little Muskingum river, Sunfish and Captina
creeks. The Little Muskingum river flows, during its entire course, in a
basin parallel to the Ohio river, and only eight or ten miles from it. The
Indian Guyandotte creek flows in a basin similarly parallel to the Ohio.
In the northern part of the district there is a pretty large area, with a
northwestern slope. This area is drained by Wills' creek, which flows
northward through Noble and Guernsey counties, and then westward and
empties into the Muskingum river above Dresden, near the north line of
Muskingum county.
The south fork of the Moxahala creek drains a considerable valley
which slopes to the north. This fork rises in the high lands between
Oakfield and Bristol, in the southern part of Perry county, and flows
northward for twenty miles. The Moxahala empties into the Muskingum
two or three miles below Zanesville. The south fork of the Licking
river flows to the northeast. Wolf creek, which rises in the northern
part of Morgan county, flows in a valley which shows a remarkable
parallelism with that of the Muskingum. It maintains an average
distance of five or six miles from the Muskingum for twenty miles, and
then, as the Muskingum turns and flows northward, in Windsor township,
Morgan county, it also bends to the north and northeast in Wesley and
Palmer townships, Washington county, and enters the former near Beverly, in Waterford township, in the same county. The south fork of Wolf
creek rises within two or three miles of the Ohio river, in Warren township, Washington county, and flows to the northward. Nearly all of the
western part of Washington county is drained by that creek, and consequently slopes to the north. These facts are of great significance as
showing original undulations of the surface, before the present work of
drainage began. How far the underlying strata show corresponding
undulations will hereafter be determined as the different parts of the
District are studied in detail. Very limited observations made in the
valley of the Moxahala appear to indicate that in portions of the val
