longing 1400 to 1800 feet below the Pittsburgh Coal, and be- 

 ing 50 to 100 feet thick, has produced little oil or gas of com- 

 mercial quantity in the two counties. Numerous shows of 

 black oil and pockets of gas are frequently found, but seldom 

 last long. 



Keener Sand. The Keener Sand, resting directly under 

 the Big Lime and representing the upper member of the Po- 

 cono, sometimes being 20 to 50 feet thick when separated 

 from the underlying Big Injun with which it is usually joined 

 without any slate parting, has not produced oil or gas in com- 

 mercial quantity in either county. It showed oil in the J. W. 

 Killingsworth No. 1 (690) well in Glenville District, Gilmer. 



Big Injun Sand. The Big Injun Sand, sometimes coming 

 directly under the Big Lime, and sometimes being separated 

 from it by the Keener Sand and accompanying slate, and at- 

 taining 50 to 150 feet in thickness, long recognized as one of 

 the most prolific oil and gas horizons in the State, has pro- 

 duced only a small quantity of either in Lewis and Gilmer. 

 It often shows oil or gas when drilled through, but has not 

 been generally productive. 



Squaw Sand. The Squaw Sand, belonging in the Pocono 

 Series and being usually regarded as a split off the Big Injun, 

 from which it is sometimes not separated, has produced gas 

 in a few wells and has also showed small quantities of oil, but 

 like the Big Injun above it, offers little hope of any extensive 

 production. Its thickness is variable, being usually not more 

 than 50 feet. 



Weir Sand. The Weir Sand, belonging 275 to 400 feet 

 below the top of the Big Lime, being frequently absent and 

 seldom more than 50 feet thick, is not generally productive, 

 t-ut showed oil in the Hazen Phillips No. 2658 (561), in Banks 

 District, Upshur, near the Lewis Line, and made gas in the 

 John G. Radabaugh No. 2588 (571) in Collins Settlement Dis- 

 trict. Lewis. 



Berea Sand. The Berea Sand, which is the bottom mem- 

 ber of the Pocono Series, being 300 to 500 feet below the top 

 of the Big Lime and usually 10 to 30 feet thick, has produced 

 a large amount of oil and gas in the two counties. In Lewis 

 it is the oil producing stratum of the Fink field in Freemans
