TENNESSEE 119 



Mr Hayes gives two sections farther east in this division — the first in 

 northern Cumberland county at probably 12 miles east from the Calf- 

 killer Creek locality, in White, and the second in central Bledsoe near 

 the Sequatchie valley. They are important as illustrating the eastward 

 thickening of the measures, and must be given in full that the change 

 from the western to the eastern conditions may be understood. The 

 Cumberland section is

1. Coarse sandstone [Rockcastle] 60 



2. Interval 100 



3. Coal bed [Sewanee] 1 11

to the Bangor limestone, showing a great increase in the sub-Bonair 

 measures and a moderate increase in the beds above. The Pikeville 

 section in Bledsoe, about 25 miles farther south, is

3. Shales and sandstone 300

It is altogether probable that the highest sandstone of this section is 

 at the Corbin horizon or very near it, as the shales overlying the Rock- 

 castle show a very great thickening in sections northeastward from the 

 Pikeville region, to which reference will be made when studying the 

 eastern escarpment. It is probable that here one finds the full presen- 

 tation of the Rockcastle formation of Crandall, the Lee formation of 

 Campbell's Kentucky folios. The Sewanee coal bed appears to be 

 absent from a considerable portion of western Cumberland and a por- 

 tion of White, but it is important in Bledsoe and most of Cumberland. 



Farther southward the region under consideration includes Grundy 

 and Franklin counties along the western border, with so much of Marion 

 as lies west from Sequatchie valley, the last two extending to the Alabama
