76 J. J. STEVENSON CARBONIFEROUS OF APPALACHIAN BASIN 



Eed beds are represented scantily in Monroe county. One of 6 feet 

 is at 36 feet below the Upper Sewickley in the southwest part of the 

 county, and an oil record reports 13 feet at 100 feet above the Pittsburg 

 in the southwest; biit exposures are so incomplete throughout that no 

 conclusion respecting distribution of these beds can be drawn.* 



Eeturning to the western outcrop in Athens county, south from 

 Morgan, one has Professor Lovejoy's generalized section for these two 

 counties :

1. Sandstone 60 



2. Coal bed [Uniontown] Blossom 



3. S.hale 10 



4. Limestone to 3 



5. Shale 35

11. Shale 10 



12. Coal bed [Upper Sewickley, Meigs Creek] — 



13. Shale and sandstone 20 



14. Limestone to 12 



15. Shale, limestone, or sandstone 10 to 75 



16. Pittsburg coal bed 



The average intervals are, Number 2, 190, and Number 12, 95 feet 

 above the Pittsburg. The great sandstone on top is evidently the 200- 

 foot conglomerate of Professor Andrews. The Pittsburg coal bed is as 

 irregular in Athens as in Morgan. It is 4 feet to 9 feet 6 inches in 

 the northeastern townships, usually absent in the central, and thin in 

 the southern portions. At one locality, where the overlying sandstone 

 is replaced by shale, thin coals are at 15 and 67 feet above the main 

 coal bed, the former underlying 14 feet of red shale ; at another exposure 

 9 feet of red shale overlie the sandstone. 



The Upper Sewickley is absent from many townships, but occasionally 

 on the eastern (Washington) border it is 6 feet thick. The interval 

 to the Pittsburg is said to vary from 95 to 128 feet, this variation appear- 

 ing to depend much upon the thickness of the sandstone deposit. Not- 

 withstanding the variations in this interval, that between the Pittsburg 

 and Uniontown (Hobson of Andrews) has 185 and 195 as its extremes.
