MONONGAHELA FOEMATION 91 



bed is rarely absent from the records and varies from 2 to 6 feet, shale 

 included, but all the records are skeleton and give no information above 

 that bed. Westward the Pittsburg soon disappears, but its place in re- 

 lation to the Logan sandstone is clear, so that the horizon is foUovired for 

 the most part without difficulty. At 8 miles west from the Doddridge 

 line the Uniontown, 2 feet thick, is about 235 feet above the Pittsburg, 

 while midway in the county it is 3 feet thick, with a streak of coal at the 

 Waynesburg horizon, 61 feet higher. North from the railroad and 12 

 miles from the Doddridge line a coal bed is at 215 feet below the "Wash- 

 ington; 9 or 10 miles southwest, near Harrisville, this bed is at 223 

 feet below the Washington, but at Harrisville no trace of coal is recorded, 

 though the bed is present 3 miles south from that village. This seems 

 to be the Uniontown, though it is about 260 feet above the calculated 

 place of the Pittsburg. All coals are wanting in the western part of the 

 coiinty, there being no trace in any record of any below the Washington. 



Limestone appears to be wholly wanting, as the drillers rarely make 

 mention of even 'limy shale;" but the red beds appear throughout the 

 section. Tabulating the records, one finds that red shale occurs in some 

 well or other at every foot in 300 feet above the place of the Pittsburg 

 coal bed. Such shale is found in widely separated wells, filling part to 

 all of the first 40 feet; thicknesses of 50, 45, 29, 35^ 26 are recorded 

 between 28 and 100 feet; between 100 and 165 feet are 60, 50, and 7 

 feet in different wells; in two wells, beds of 60 and 31 begin at 165 feet; 

 in three wells one finds beds 85, 110, and 25 feet, beginning at about 180. 

 The interval 180 to 290 feet is marked by thick red beds, sometimes a 

 continuous mass ; at others divided into two or more ; in one case divided 

 by the Uniontown coal bed. The highest which can possibly be in 

 the Monongahela is at 308 feet, 10 feet below a sandstone which may be 

 the Waynesburg. Two great beds are on the west side of the county, 75 

 and 100 feet thick, but it seems hardly possible to determine their rela- 

 tions.* 



Wirt county is southwest from Eitchie. Very little information is 

 available for this county. The Pittsburg is brought to the surface in 

 the Cowrun anticline, or "Oil-break," and a section by the late Mr Min- 

 shall obtained near Burning Springs shows :
