THE PREGLACIAL DRAINAGE OF OHIO. 43-' 



Allen counties ; (2) following the channel westward in Indiana. 

 These points will be considered in order. In Washington town- 

 ship, Auglaize county, Ohio, near the Shelby county line, a well 

 in section 23 shows 298 feet of drift ; while in section 22 imme- 

 diately to the west there are 76 feet only. In section 14 due 

 north from 23 a well showed 300 feet of drift without striking 

 rock. The depth of drift outside the channel in this locality 

 cannot be stated since no wells have been drilled there. 



In Wapakoneta two wells have been sunk, one on the east 

 side of the city and the other on the west. The former disclosed 

 125 feet of drift and the latter 90 feet. One mile north of the 

 last well 130 feet are found. One and one-half miles northeast 

 of Wapakoneta in section 16 two wells disclose depths of drift of 

 398 and 400 feet, with a mile and one-half northwest only 68 

 feet are found. This shows a drop in the rock floor of 332 feet 

 in the surface distance just given. 



The next point at which the channel is struck is in section 

 34, Duchouquet township. These wells are near the village of 

 Cridersville and just south of the Allen county line. Two wells 

 there disclose depths of drift of 400 and 486 feet; while within a 

 mile either east or west of these the depth is less than 130 feet. 

 From Cridersville the channel runs northeast into Perry town- 

 ship, Allen county. In the northeast corner of section 25 there 

 are 394 feet of drift, while one-fourth mile due south from this 

 there are only 166 feet, and one-half mile northwest only 123 feet. 

 Obviously the channel is here very narrow. To the northeast 

 in section 20 there are 350 feet, but beyond this the drill dis- 

 closes no marked variations in depth of drift, and so the channel 

 could not be followed farther. The apparent shallowing of this 

 channel to the northeast indicates that the flow of water was to 

 the southwest. 



In German township, Allen county, from three to five miles 

 northwest of Lima, several comparatively deep drives are found. 

 In section 15 there are 235 feet; in section 16 there are 262 feet; 

 in section 8 there are 214 feet. But these depths of drift are inter- 

 mingled with very much shallower ones, so that their interpre- 

 tation is not easy. Possibly they may result from several deep 

 but very narrow canons.
