The conglomerate at the bottom, also present in Penningtons gap, 

 where it is certainly much thinner, is a new member or at least it can not 

 be recognized, in descriptions of sections farther south. It may be the 

 lowest sandstone of Bradley's Harriman section, which rests on shales, 

 of which much belongs to the Pennington (Shenango) of Campbell, and 

 it may be the lowest conglomerate referred to b}^ Mr Keith. A coal bed 

 at 20 to 30 feet below this conglomerate is described by Campbell as a 

 very fair cannel. Accepting the reference of the conglomerate as given 

 above, this coal bed would be at the place of Bradley's Coal A, and some 

 of the shales assigned by Campbell and Stevenson to the Lower Car- 

 boniferous should be placed in Pottsville. 



The Norton formation extends upward to a bold sandstone, the 

 Gladeville, which was traced through Lee and Wise counties of Virginia 

 and Harlan of Kentucky. The thickness of Norton, as given by Camp- 

 bell, is fully 500 feet greater than Stevenson's estimate, obtained by tying 

 together two sections which evidently were not continuous. Mr Camp- 

 bell gives two measured sections in the western part of Wise county, 

 which together show the upper part of the Norton, and Stevenson gives 

 one in Lee county for the lower portion, the thicknesses being largely 

 estimates. Though not continuous, these enable one to get such under- 

 standing of the succession as is necessary for comparison with adjacent 

 areas in Tennessee and Kentucky. The section by Mr Campbell in- 

 cludes the Gladeville sandstone and seme higher beds which are im- 

 portant in this connection. It is
