portion of the Wakatomaka which hes so nearl)' coincident 

 with the boundary between Licking and Coshocton Counties 

 formerly constituted a part of the main axis of the Old Hanover 

 Creek or whether the tributary which parallels this portion of 

 the creek about two miles further to the East may h.ive prev- 

 iously received its headwaters from further North, and hence 

 have been the main line of drainage, was left an open question 

 for the field work to settle. 



Finally, with regard to the Rocky Fork, it seemed quite 

 evident that from the point where tliat stream turns South its 

 upper waters must, in preglacial times, have flow^ed either 

 northwest into the Old Mt. Vernon River or southwest into the 

 North P'ork. They may have even been divided, portions 

 going into each basin. In how far these hypotheses accorded 

 with the facts is now to be seen. As the field work had to be 

 done on Saturdays and during brief two- and three-day recesses 

 in regular school work I found it impossible to make a strictly 

 consecutive study of the whole area. Consequently the single- 

 day periods were utilized for working up that portion of the 

 region which was near at hand, while more distant sections were 

 reserved for times when trips of a few days length would make 

 visits to them more profitable. — All of which is to explain why 

 no attempt will be made to present the facts in the order in 

 which they were gathered and studied. 



As it was at first deemed that the location of the preglacial 

 Walhonding would have an important bearing upon the settle- 

 ment of minor modifications in its locality, that part of the sub- 

 ject will be taken up first. After preliminary trips, one up the 

 Walhonding from Coshocton to some four miles above Warsaw, 

 the other up the Old Hanover Creek, it was decided that the 

 most economical as well as the surest method would be to trav- 

 erse the present water shed extending from Coshocton west- 

 ward between Wakatomaka and the Walhonding. Such a trip 

 was taken in company with Professor Tight and resulted in 

 demonstrating that the water shed referred to is a rock ridge 

 throughout its whole length and contains no gaps sufficient 

 either in width or depth to have ever carried even a small part
