than at points above or below, for the valley is exceptionally narrow there. 

 The bordering uplands also reach a higher elevation there than in other 

 parts of this section of the Muskingum. 



DRAINAGE TRIBUTARY TO THE WESTWARD OUTLET. 



The portion of the westward outlet between Dresden and Newark 

 apparently received the drainage from about the same territory as is now 

 tributary to Wahatomaka Creek and the lower course of Licking Kiver. 

 The headwater portions of the North Fork and the Middle or Raccoon Fork 

 of Licking River appear to have discharged directly westward into the 

 Scioto Basin, as determined by Tight, there being an old divide crossed by 

 the Raccoon Fork near Grranville, and by the North Fork south of Utica.^ 

 The South Fork of Licking once received a larger drainage from the east 

 than it does at present. Jonathan Creek, wliich now leads eastward into 

 the Muskingum from near the Licking reservoir, crosses an old divide at the 

 narrows in its lower course near Fultouham, as determined by Tight and 

 Davis.^ The greater part of the old di-ainage was in the reverse direction 

 from the present stream, and entered the old outlet near the Licking 

 reservoir. Farther south the old outlet received the headwater portion of 

 Hocking River from as far down as Rockbridge, in northern Hocking 

 County, including the entire drainage basin of Rush Creek. It also received 

 the drainage of the district now tributary to Little Walnut Creek, a portion 

 of the outlet now being followed by the creek. 



CHANGES IN OWL CREEK DRAINAGE BASIN. 



Owl Creek, which drains tlie greater part of Knox County and adjacent 

 parts of Morrow and Richland counties, unites with Mohican Creek in west- 

 ern Coshocton County to form the Walhonding River. It is the first 

 drainage line of importance that leads into the Muskingum from the west 

 above the old outlet. The changes of drainage which it has experienced 

 were partially worked out and discussed by Read prior to 1878.^ The 

 writer examined the drainage basin in 1890, and subsequently it was 

 examined by Tight and his assistants. It has been noted by each of the , 

 persons who have examined this drainage basin that the stream crosses an
