The feature of especial interest is the presence of red, blue, and varie- 

 gated shales so far down in the section. Number 6 is certainly not 

 higher than the Rockcastle sandstone ; yet below it is a mass of shales 

 suggesting the Conemaugh conditions. The interval from the top of the 

 Upper to the bottom of the Lower conglomerate is practically the same 

 as in the other section. The Etna and " Dade " coal beds are mined 

 within 2 miles of this locality. ^ The beds numbers 2 and 5 were seen 

 b} r Mr Hayes, who gives about 60 feet as the interval. The lower bed 

 is of importance. Number 13 is at the horizon of the Sewanee, while 

 the two thick beds are at the horizon of important beds in southern 

 Kentucky.* 



Passing over into Alabama, one finds Mr McCalley's general section of 

 the measures,
