as a massive sandstone at 25 feet below the Sewanee. The Soddy coal 

 bed rests almost directly on the Etna (Cliff) conglomerate. The Etna 

 (Cliff-Castle Rock) coal bed is 3 feet thick and is mined. The Dade 

 coal bed of Mr Hayes' Etna section is here at 100 feet below the Etna 

 coal, approximately the same distance as in that section ; but here it is 

 not of workable thickness. 



Mr Hayes' section at Rathbun, a few miles northeast from the Daisy 

 mines, is important ; it is as follows, the identifications in brackets being

The interval between Bonair and Etna is 158 feet; at Daisy, it is 170, 

 and at Etna, 140. The Sewanee is 283 feet above the Etna conglomerate, 

 and underlying the sandstone is the Walker, which may be, as Safford 

 suggested, merely a split from the Sewanee. Four coal beds are present 

 in the interval between the conglomerates and three of them are of work-
