showing in all about 530 feet of the Norton. In Stevenson's section at 

 Penningtons gap traces of coal were seen at 25 and 150 feet above the 

 " Bee rock, 1 ' while at 235, 318, 380, and 417 feet are beds which some- 

 times attain workable thickness. A massive sandstone is present at 

 about 325 feet above the " Bee rock." 



In Harlan county of Kentucky, along the foot of Pine mountain and 

 southward, the Norton appears to hold no important bed of coal, aside 

 from that immediately underlying the Gladeville sandstone. Shales 

 375 feet thick overlie the Lee formation, with a 1-foot coal bed at the 

 top, immediately underlying a massive sandstone, which is a notable 

 feature in the topography, and clearly the same with at 325 feet above 

 the Lee in Penningtons gap. The Gladeville sandstone is a marked 

 feature in valleys on the southeast side of the county, and the coal bed 

 underneath it becomes at times 5 feet thick. The Lower Splint coal bed 

 resting on the Gladeville varies greatly, but is persistent and of great 

 commercial importance. The Upper Splint is from 65 to 100 feet above 

 the Lower, and the " Cannel " is 21 to 60 feet higher. On Little Black 

 mountain the Cannel is 150 to 160 feet above the Lower Splint. The 

 " Imboden " coal bed, though attaining great thickness in western Wise 

 county, becomes insignificant in Lee, where it was not identified posi- 

 tively by Mr Campbell. Eastward it was followed to very near the line 

 of Dickenson and Russell counties. The Cannel and Splints overlying 

 the Gladeville sandstone were traced by Mr Campbell to the Dickenson 

 line, about 20 miles from Pound gap, in the Elkhorn region of Kentucky. 



Mr Hodge found a persistent fossiliferous limestone, 1 to 3 feet thick, 

 at about 725 feet above the Imboden coal bed in Little Black mountain 

 of Wise county.
