108 J. J. STEVENSON — CARBON TFEROtlS OF APPALACHIAN BASIN 



junction can not be made. The conglomerate appears to follow the Fer- 

 riferous along the western edge of the basin.* 



The effort now is to trace the section through the more southerly 

 counties of Kentucky, where the section begins to show extreme varia- 

 tion — a fact of some interest in view of the other fact that along the 

 western border in this region the Rockcastle group begins to assume the 

 proportions so notable farther south. 



The Kentucky river is formed in Lee county by the union of three 

 forks ; the South fork, rising in western Bell county, flows northward 

 through Cla} T and Owsley to Lee, which is south from Wolfe and east 

 from Estill ; the Middle fork, rising in Leslie, east from Clay, flows 

 northward through Leslie, Perry, and Breathitt into Lee, while the 

 North fork, rising in Letcher, flows through Letcher, Perry, and Breathitt 

 into Lee and receives tributaries also from Wolfe. This region was 

 studied by Mr Hodge. 



Mr Hodge remarks that a noteworthy change in composition of the 

 rocks takes place beyond a line extending across northwest Breathitt, 

 southeast Owsley, and northern Clay. Up to this line from the north- 

 west, the rocks above the Sharon sandstone are largely shale, but thence 

 south east wardly the shales are replaced in great part by sandstone and 

 the measures thicken rapidly. 



In central Wolfe county, at some distance south from Mr Lyon's line, 

 Mr Hodge finds this succession, the identifications being b}^ the writer :

10. Calcareous shales 27 



1 1 . Coal bed [Sharon] 



Mr Hodge regards numbers 3, 7, and 11 as coal beds 3, 2, and 1 of the 

 Kentucky series. Number 9 is the little coal bed seen at so many places 

 between the Quakertown and the Sharon, and number 5 is evidently the 

 same with the upper split of the Quakertown, which has been followed
