proper soils are found in decomposed limestone gravels, but oftener in the 
weathered outcrops of rocks 4n eetu. 
As in the other counties of this range, the water supply is not wholly 
satisfactory, but the condition in this respect is somewhat better than in 
Clerment. In the flat lands the only safe and sufficient supply must be

The surface of the county, through its central and southern townships, 
is highly diversified. Several tributaries of the Ohio have cut deep 
valleys, and descend them with a comparatively rapid fall. 
The most considerable topographical feature of the county is the 
valley of White Oak Creek. Straight Creek and Hagle Creek rank 
next in size and importance.
