The Lyon Well was bored at the point of Paint Creek, 

 where its South, or Little (Oil) Fork, and its North, or Open 

 Fork, unite. The well-house stands on a plate of rock a few 

 feet above the water-bed. A well was blasted through 20 

 feet of massive sandrock, under which the auger went down 

 through 2 feet of shale, followed (at intervals not now remem- 

 bered by Mr. Lyon, whose record of the well is lost) by 

 micaceous sandstone, 33 feet of shale, blue sandstone, Avhite 

 marble, and blue limestone, to a depth of 213 feet.* Shows 



* The men on the ground told me that 30 feet of blue slate rock was 

 the first bored through, beginning, say, 10 feet beneath the bed of the 

 creek ; then a thin but very hard rock. They said that this Belt of slate 

 was struck in the three wells on the creek above and below the Lyon 

 "Well, viz., the Donnell Well, bored 200 yards below the Lyon well, 

 and 200 feet deep, the second Lyon Well, and the Warner Well, both 

 near together, about half a mile up the Oil Fork, and 100 to 140 feet 

 deep, quitting in hard rock. In the Lyon Well, they thought they 

 struck a very hard thin rock about 140 feet down, and another 260 feet 

 down, whereupon the auger fell 4 inches, and the gas blew the oil to the 

 surface, and it began to flow. Such details from memory are worth 

 little.
