4. At Mannington, also in Marion county and 8 miles southwest from 

 Fairview, one has A. J. Montgomery's record of the well drilled by him 

 for Doctor White, which gives the succession in detail and shows the in- 

 creasing thickness of Conemaugh, the intervals being 607 to the Upper 

 Freeport, 807 to the Clarion, and 845 to the Pottsville, which shows

 one finds the beginning of a change, which is complete in the next sec- 

 tion, the record of a well at Joetown, 9 miles southwest from Manning- 

 ton, which shows

428 feet and resting on the limestone. At Fairview a thin coal bed is 

 shown at 11 feet above the Pottsville ; at Mannington it is in shale at 21 

 feet, while here it is represented by 5 feet of black shale. Number 3 is 

 divided by 3 feet of black shale at 32 feet from the top. The upper 

 part of the section, numbers 1 to 4, is that which is familiar in Monon- 

 galia, Wetzel, and northern Marion, equivalent evidently to the Home- 

 wood, Mercer, and Connoquenessing, with the Sharon coal bed (Camp- 

 bells Creek) underlying the last. The interval from the Pittsburg coal 

 bed to the Great Limestone is 1,243 feet at Fairview, 1,241 feet at Man- 

 nington, and 1,240 feet at Joetown. The section below number 4 is 

 clearly equivalent to the red rock and other materials between the Sharon 

 coal and the Limestone, of which one finds at Fairview 165 feet, at 

 Mannington 111 feet, and here feet, while the interval from number 

 4 to the limestone is 161 feet. 



At about 15 miles west from Joetown, a well in Wetzel county shows 

 the Roaring Creek and Pottsville in contact, the top of the latter being 

 at 809 feet below the Pittsburg coal bed, the succession being
