56 THE PREGLACIAL DRAIXAGE OF OHIO. 



level, making three broad and deep breaches between the prime 

 obstacles barring the glacier's even progress. Huge as it was 

 its course was modified. 



Striae on the hills of Summit county are directed south- 

 west, while on the pure Waverly of Richland and Ashland coun- 

 ties they are southeast; these scorings if projected would meet in 

 the Killbuck valley. How could such scorings be produced? 

 Is it not plain to anyone with operative intelligence, and a mind 

 unbiased by pre-conceptions, that the broad inclined plane from 

 Mansfield to Wooster, facing the high range of hills bordering 

 the Tuscarawas valley from Alassillon to Akron, would of neces- 

 sity influence the ice-front, when a lower plane was there, and 

 lead you to expect and search for just such glacial scratchings? 

 Here were two forces acting the one against the other, and to 

 gether they directed a lob of the glacier that had entered the 

 inviting depression created by the three open channels across 

 Cuyahoga , eastern Lorain, western Summit, Medina and Wayne 

 counties until it was stranded as a bow on the hard high hills of 

 Holmes county, just before it reached the continental divide 

 of the Coal ^Measures; this bow a little more than subtends 

 the south front of Wayne county, the bowstring being about 

 30 miles long, while the central projection is about 8 miles to 

 Millersburg, with the Killbuck valley as a fixed arrow in the 

 bent bow, 



This lobe of the glacier seems to have become detached 

 from the main body just where the Coal Measures end below 

 Loudonville in Ashland county, for the main mountain of ice 

 slid on south over the smoother face of the Waverly that skirts 

 the Coal Measures to below Newark, before it was deflected — 

 a distance of 40 miles. Xow, it was this arrested lobe of the 

 glacier, that brought the load of material that changed the 

 entire topography of the hydroghaphic basin described in this 

 paper; from Cleveland to ^^lillersburg, and from Alassillon to 

 Mansfield, its burden of Life in Death was put down, giving a 

 new physiognomy and a new physiology to the landscape; and 

 the remodeled features, with their fresh expressions, made the 

 face of this valley a thing a beauty to the eye and a blessing to 

 the nation; the angular hills and gorge-like valleys, were rounded
