CHAPTER LXXV. 



REPORT OF THE GEOLOGY OF SHELBY COUNTY. 



BT JOHN HU8SET. 



This county is situated in the second tier of counties from the bound- 

 ary line between Indiana and Ohio, and about half-way of the State from 

 north to south. It is bounded on the north by Auglaize county, on the 

 east by Logan and Champaign, on the south by Miami, and on the west 

 by Darke and Auglaize. The county seat is Sidney. The water-shed 

 between the Maumee and Miami River systems is partly in the northern 

 part of this county.. The road known as the Kettler turnpike, in a gen- 

 eral way, may be regarded as marking the line of the water-shed, at least 

 for some miles of its course, nearest the Laramie Reservoir. The water- 

 shed bears to the north-east, after leaving this county, into Hardin and 

 Wyandot counties. 



ELEVATION OP THE COUNTY. 



At Cincinnati, low water in the Ohio River is four hundred and thirty- 

 two feet above tide- water, and the water in the Sidney Feeder is five hun- 

 dred and twelve feet above low water in the Ohio, or nine hundred and 

 forty-four feet above tide-water. The greatest elevation yet measured in 

 the county is one hundred and thirty-four feet, on the Towana turnpike, 

 east of the Miami River. The line between this county and Champaign, 

 on this turnpike, is one hundred and twenty-one feet above the water in 

 the feeder. The greatest elevation on the line of the Stewart turnpike 

 is one hundred and twenty-one feet, and on the line between Shelby and 

 Logan counties one hundred and eleven feet above the water in the 

 canal. On the Infirmary turnpike the greatest elevation is eighty-seven 

 feet, and at the end of this road, on the line between this county and 

 Miami, it is forty feet below the level of the canal. On the St. Mary's 

 turnpike, about two miles from Sidney, the highest point is reached at 

 one hundred and twelve feet above the water in the canal. The bottom 

 of the reservoir is about eight feet above the water in the canal. The 

 main canal extends entirely across the county, running in a north-
