T^8 PETROLEUM AND NATURAL GAS. 



800 feet below the Pittsburgh Coal, and being from 25 to 75 

 feet thick. It has not produced oil or gas in quantity any- 

 where in the two counties, but shows of both, as well as 

 abundant salt water, are sometimes found. 



Gas Sand of Rosedale. At Rosedale, Braxton County, 

 just south of the Gilmer Line, several wells have been drilled 

 that show gas in commercial quantity in a sand that comes 

 1500 to 1525 feet below the Pittsburgh Coal horizon and which 

 has been called the "Gas Sand" by the drillers in that locality. 

 This sand is the next to the lowest sandstone member of the 

 Pottsville Series, which is expanded in that region to a total 

 thickness of nearly 800 feet. Sufficient evidence is not avail- 

 able to show whether this sand correlates with any definitely 

 named formation of the Pottsville in northern West Virginia, 

 and it will be referred to as the "Gas Sand of Rosedale." 



Salt Sand of Rosedale. The Salt Sand of Rosedale, which 

 is a prolific oil horizon in that locality, coming about 1625 feet 

 below the Pittsburgh Coal, and being the lowest sandstone 

 formation of the Pottsville, seems to correlate with the lower 

 Salt Sand of northern Lewis. This sand produces a consider- 

 able quantity of oil at Rosedale and also in Courthouse Dis- 

 trict, Lewis, where a small pool has been found on Murphy 

 Creek. It is the gas horizon of the Stumptown region in Gil- 

 mer and at various other points has produced oil and gas. 

 Along the synclines it is nearly always barren of oil and gas, 

 owing to the great amount of water that it contains. 



Maxton Sand. The Maxton Sand, belonging in the 

 Mauch Chunk reds, has produced oil and gas in considerable 

 quantity at numerous points in the two counties, but because 

 of its lenticular character, must be classed as an uncertain 

 economic horizon. 



Little Lime. The Little Lime, which occurs near the 

 base of the Mauch Chunk Series, 1375 to 1775 feet below the 

 Pittsburgh Coal, depending on the locality, and being 10 to 

 30 feet thick, is not generally productive, but made an oil 

 show in the J. C. Marsh No. 1 (281) in Freemans Creek Dis- 

 trict, and flowed oil in the M. O. Edwards No. 996 (473) in 

 Courthouse District, Lewis. 



Big Lime. The Big Lime, or Greenbrier Limestone, be-
