to have reached the rock. The village is supplied with gas from a well 

 southeast of it. This is reported by the owner, J. C. Wakefield, to have a 

 pressure of 22 pounds to the square inch from a 2-inch pipe, and during 

 the winter of 1896-97 it supplied fuel for 200 stoves. The gas may be 

 derived in part from underlying Coal Measures shale, but muck beds 

 inclosed in the drift afford a probable source. A section of the drift beds 

 penetrated appears on page 215. 



The wells in the following table are the deepest of which records were 

 obtained, and include but a small part of those which have been sunk in 

 the county. There is probably not a township in the county which does 

 not include several wells over 100 feet in depth.
