Here one reaches the higher measures again. The succession above 

 the Nelson (Sewanee) coal bed appears to be clear ; the sandstone, num- 

 ber 15, is that so persistent between the Bonair and Rockcastle ; number 

 11 is the Rockcastle, about 280 feet above the Bonair, and number 1, at 

 about 330 feet above the Rockcastle, is in place of the Corbin,that being 

 very nearly the interval at Pikeville, almost due west from Dayton. If 

 these identifications be correct, the Richland coal of Hayes is at the 

 horizon of the Barren Fork coal bed in Pulaski county of Kentucky. 



No section or note is available for the region northeast from Dayton 

 until Rockwood, 30 miles distant, in Roane county, is reached. There
