TUSCARAWAS COUNTY. 53 



between Dover and New Philadelphia are underlain by two hundred feet 

 of sand, gravel, and bowlders, which have been filled into the old valley 

 since the remote period when the continent stood higher; the drainage 

 was freer than now, and the Tuscarawas flowed with a rapid stream far 

 below its present bed.

In the northern part of Tuscarawas county the rocky strata are some- 

 what covered with Drift, especially in the valleys, but in all the central 

 and southern portions of the county, the highlands are without drift, the 

 slopes of the hills, ravines, and roads showing the geological structure 

 distinctly, and the soil is derived exclusively from the decomposition of 

 the underlying rocks. This difference in the character of the surface 

 deposits is also indicated by the material transported by the streams. 

 Most of those which flow from the north bring down drift-gravel and 

 bowlders, and have sandy or gravelly bottoms; while those which flow 

 into the Tuscarawas from the south, south-east, and south-west, carry 

 only the wash from the shales of the Coal Measures, and their valleys 

 have clay bottoms. 



The soil of Tuscarawas county, being for the most part of local origin,
