282 I. c. WHITE — oinoiN of geaitamite 



does south from it. The oil occurs in the Big Injun sand, and in one 

 of the wells on the Brooks farm a peculiar bituminous substance was 

 encountered saturated with petroleum, and described by the drillers as 

 tougii and hard to penetrate — " drilling like rubber," as one expressed 

 it. The deposit was reported as 8 feet thick, and lying directly on top 

 of the Greenbrier limestone, or 67 feet above the Big Injun oil sand. 

 Some of the material was washed out of the sand pumpings by Professor 

 John F. Carll, the geologist, Avho kindly gave me samples for analysis, 

 since its singular geological horizon suggested the idea that it might be 

 grahamite. 



GEOLOGICAL RELATIONS 



The following record of Books well number 1, Whiskey Run oil-pool, 

 received from Mr Carll, will show the geological relations of the mineral 

 in question :

SUGGESTED ORIGIN 



The coaly material at 1,680 feet was found onl}^ in this Brooks well 

 number 1, although many other wells have been drilled within short 

 distances from it on the Brooks farm and others adjoining; hence it is
