288 Clara Gould Mark 



North of this hill 13 feet of the Mercer limestone is shown along 

 the highway, its base being about 110 feet below the flint on top 

 of the hill. A coal drift in the field to the west is apparently at 

 the same level as the base of the Mercer. 



The top of Fairview Knob is fairly well covered with masses 

 of flint, but the underlying impure limestone was found in wood- 

 chuck burrows almost to the top, which indicates that only the 

 lower part of the flint is left. This impure limestone contains 

 numerous irregular cavities out of which clay -like masses have 

 weathered. In the blocks not weathered so much the clay fillings 

 were found. The limestone contains the same fossils as those 

 collected on Buzzard Glory Knob. 



This Logan Stevens Farm. On this farm, a mile and a half 

 west of Fairview Knob, a well was drilled for oil in the summer of 

 1908. A large amount of the flint is shown in the road on the 

 ridge just east of this well, and in the lane near Mr. Stevens' 

 house the Homewood sandstone is exposed. According to the 

 barometer this exposure of Homewood sandstone is 45 feet below 

 the flint on top of the ridge, and the derrick floor at the oil well 

 is 110 feet lower than the sandstone. The Mercer limestone on 

 the Flint Ridge road to the north is 75 feet higher than the derrick 

 floor, or 35 feet lower than the sandstone. The following record 

 was obtained from one of the well drillers:

 vonian and Monroe limestones as well.
