CHAPTER XL VI. 



REPORT ON THE GEOLOGY OF AUGLAIZE COUNTY. 



BY N. H. WINCKELL. 



SITUATION AND AREA. 



Auglaize county lies immediately south of Allen. It is bounded east 

 by Ha/din and Logan, south by Logan and Shelby, and west by Mercer. 

 Its county seat, Wapakoneta, is situated on the Auglaize River, thirty- 

 six miles from the Indiana State line, and seventy-nine from the Michi- 

 gan State line. The area of the county is three hundred and ninety- 

 eight square miles. It has an irregular general outline. Its length east 

 and west is about thirty-nine miles. Its width varies from seven and a 

 half to twenty-three. 



NATURAL DRAINAGE. 



Its situation is near the summit, but on the north side of the broad 

 watershed between the Ohio and Lake Erie. Indeed, some portions of it 

 are drained southward through the Muchinippic Creek into the Miami 

 River. It necessarily contains no large streams. Those in the eastern 

 part of the County present the same peculiarity of direction as already 

 noted in the case of the streams of Allen county. They flow toward the 

 south-west or west, turning at right angles toward the north-west or 

 north. Some of those again which have acquired a northerly direction 

 are diverted a second time from their most direct course, and are made to 

 run diagonally across the general slope of the country. Thus the St. 

 Mary's, after passing one such barrier at the village of St. Mary's, en- 

 counters a second near Kossuth, which it cannot pass, but maintains a 

 diagonal instead of a direct descent to its junction with the St. Joseph, 

 in Indiana. These streams are to a great extent dependent on springs 

 from the gravelly reservoirs embraced within the Drift. The St. John's 

 Ridge serves at once as a barrier to the Pusheta Creek, which flows 

 along its upper or southern side, and as the reservoir from which flow 

 northward a number of the tributaries of the Auglaize. Gravelly de- 

 posits in the same ridge give rise to springs in such numbers in the
