this point eastward the valley widens and deepens again. Very 

 soon it begins to fill again with deposited material, probably 

 the most of it carried in by the glacial stream. Two miles 

 above the junction with Mohican marked terraces are seen. At 

 a point rather less than two miles above the junction of the two 

 streams a somewhat startling narrowing of the valley was noted, 

 but a careful examination failed to reveal any decided signs of 

 an eroded col. And under the circumstances of the col further 

 up stream it would require very convincing evidence before I 

 would locate an old col at this point. 



As one comes down into the valley of the Walhonding it 

 is at once evident that the lower part of Owl Creek, that part 

 below the Milwood col, and the Walhonding, originally formed 

 a single continuous axis, to which the drainage brought in by 

 what is now the lower portion of the Mohican made only a very 

 inconsiderable addition. Now the last named stream probably 

 brings in more water than Owl Creek. At the point of junction 

 and for a considerable distance up stream from that place the 

 valley of the Mohican is deep and narrow with quite steep walls 

 and a tortuous course — all the indications of an insignificant 

 pre-glacial existence. In .mother place we have the observation 

 that this character is entirely lost in the upper portions of the 

 stream where it is flowing in the valley of the Old Mt. Vernon 

 River. 



From its formation to Coshocton, a distance of some 20 

 miles, the Walhonding winds about on the flood plain of 

 an old pre-glacial valley. Rock clifls all along this valley, 

 showing where long points between tributary holkiws and 

 ravines have been cut awa}', may be due in part to a recent 

 period of rapid erosion as by the action of glacial waters, and in 

 part to the ordinary phenomena of stream action. Throughout 

 the whole distance from tlie junction of Owl and Mohican 

 Creeks to Coshocton there is not the sign of a gorge to indicate 

 the possibility of an eroded col. At no place is the Walhond- 

 ing flowing on rock bottom where such rock bottom represents 

 the maximum depth of the pre glacial drainage for that immed- 

 iate section of the valley. And if we restore the cols on Owl
