WELLS IN THE WELLSVILLE QUADRANGLE. 
Along the north edge of the quadrangle the convergence sheet is 
governed by two wells on the south edge of the Wellsville quadrangle, 
as follows: 
New Cumberland gas well .—This well is situated on the farm of 
J. B. Campbell, at the north end of New Cumberland. The mouth 
of the well is at an elevation of 655 feet. The Lower Kittanning 
coal outcrops at an elevation of 737 feet east of the well and at 703 
feet across the river to the west. The elevation of this coal bed 
directly above the well would be about 725 feet, or 70 feet above the 
mouth. The interval between the Lower Kittanning coal and the 
Pittsburg coal is 695 feet. Therefore the Berea sand is about 1,354 
feet below the Pittsburg coal.

Edmonston well .—The J. & J. Edmonston well is situated near the 
south edge of the Wellsville quadrangle, west of Knoxville. The 
Berea sand was found at a depth of 1,355 feet. The well mouth is 
at an elevation of 1,103 feet. The well passed through the Pittsburg 
coal at a depth of 10 feet. The Berea sand is therefore 1,345 feet
