thence to the mouth of Indian creek it is irregular, sometimes reaching 

 fifty degrees. 



Clinch river cuts the New Garden fault in the bend opposite the mouth 

 of Indian creek. The Knox limestone is on the southerly side of the fault 

 with the Lower Carboniferous shales in contact with it. On Middle creek, 

 these shales are reported to extend to very near the coal mines. The 

 Stony Ridge fault develops quickly, for the Devonian and the Lower Car- 

 boniferous are well shown on forks of Indian creek between the New 

 Garden and Stony Ridge faults. The road leading from the mouth ot 

 Indian to Baptist valley lies in the shales to Low's fork of Indian, about 

 four miles from mouth of Indian, On Low's fork one comes quickly to 

 the Lower Carboniferous limestones, many of which are full of well-pre- 

 served fossils. The bottom of the group is reached at the main creek and 

 the Chemung sandstones with Productella and Spirophyton are exposed 

 just beyond on Laurel fork. The old Christian coal mines on Laurel fork 

 are nearly two miles from, the Baptist Valley road, and are in the Lower 

 Coal measures or Quinnimont group. The main fork of Indian creek, 

 rising near J. B. Young's house in the " Sinking Waters" region, flows 

 for most of its length through the Lower Carboniferous beds, though 

 occasionally passing over to the Chemung. Very fine specimens of Pen- 

 tremites, Ttrebratula and Athyris have been obtained here. 



The road following Indian creek to its head crosses the summit to Dry 

 fork of Sandy river, reaching that stream at about two miles below the 

 Gap store on the Baptist Valley road, the distance being measured along 

 the stream. The course of this stream is very irregular, and often follows 

 the strike of the beds for a considerable distance. The Devonian rocks 

 are exposed at a little way below where the stream was reached, but no 

 details were obtained respecting them or respecting a limestone which 

 was seen at nearly a mile further down the stream. 



The Stony Ridge fault is reached at three and a half miles from the Gap 

 store or one mile above the mouth of Dick's creek. There a thick bed ot 

 sandstone belonging to the Lower Coal measures is shown at the roadside 

 dipping at a very high angle, while at a few rods further down, but on 

 the opposite bank, D. G. Sayers once opened a coal pit. These rocks con- 

 tinue to the mouth of Dick's creek, beyond which no observations were 

 made along this stream ; but the writer was informed at the mouth of that 

 creek that no limestone occurs on the Dry fork between that place and 

 the State line. The limestone certainly makes its appearance within a 

 very little way east from the Dry fork. 



The road to Crockett's cove leaves the 'Dry fork at Dick's creek and 

 turns from the creek northward within about a mile. Tlie Lower Car- 

 boniferous beds are reached at about three miles from the mouth of Dick's 

 creek. The limestones form a high ridge, only three hundred feet lower 

 than the Stony ridge, made up of Quinnimont sandstones. The whole 

 strip of Coal measures, fronting on the Stony Ridge fault, is not more than 

 a mile wide. The strip of limestone and Devonian gives the cove, a pleas-
