MONONGAHELA POBMATION 67 



has 50 feet of limestone. The interval from Waynesburg to Pittsburg 

 along the western border of Jefferson county is 140, 171, 182, 309, and 

 235 feet, and at 4 miles east from the last is 245 feet, 10 miles north from 

 Wheeling, where it is approximately 260 feet. The Waynesburg is 

 ISTumber 11 and the Upper Sewickley is Number 10 of Stevenson's 

 Jefferson County report. 



Professor Brown finds the Upper Sewickley (Meigs Creek) at 92 

 feet above the Pittsburg, on the Harrison county line. In Harrison, 

 west from Jefferson, the generalized section shows : 



Feet Inches 



1. Waynesburg (11) coal bed 2 



2. Mostly sandstone 91 



3. [Upper Sewickley] (10) coal bed 11 . 



4. Sandstone 60 to 75 



5. Coal bed [Redstone (?)] 2 6 



6. Mostly limestone 15 to 30 



7. Pittsburg coal bed. 7 to 8 



Here, as in Jefferson county, a coal bed (12) is at 50 feet above the 

 Waynesburg. The Upper Sewickley, insignificant in most of Jeffer- 

 son county, is an important bed, triple, the middle bench 4 feet 6 inches 

 and the others 1 foot 2 inches. It averages about 90 feet above the Pitts- 

 burg, though at times decrease in the lower interval makes it less. The 

 limestone above the Pittsburg is replaced by sandstone along the western 

 outcrop. There are mere traces of the Benwood limestone, but at times 

 a thin limestone appears below the Waynesburg coal bed which may 

 represent the Uniontown. The Pittsburg coal bed in the main division 

 varies from 4 to almost 6 feet and the coal is much more variable in 

 quality. At some localities it is excellent, while at others it is decidedly 

 inferior. The roof division is of uncertain occurrence, being absent 

 from considerable areas. It is usually thin, little more than one foot, 

 but it was measured 4 feet at one pit, where the whole thickness was 

 not exposed.* 



Eeturning to the Ohio river, one enters Belmont county, south from 

 Jefferson and Harrison. At Bridgeport, opposite Wheeling, Stevenson 

 found the Waynesburg (11) coal bed 245 feet above the Pittsburg by 

 barometer, 3 feet 6 inches thick, 2 feet above a limestone and 188 feet 

 above a thin coal bed, apparently the Lower Sewickley of the Wheeling 

 section. Professor Brown saw the Eedstone near by at 20 to 23 feet
