The record of a boring at Charleston, on the Kanawha, suffices to link

Number 1 is the Stockton, number 5 the Winnifrede, and number 8 

 the Campbells creek. Number 3 may be the Lewiston. The great mass 

 of shales observed in so many sections toward the west has become un- 

 important and the Lower Pottsville shows no shales or coal in the record. 

 The Stockton coal bed is about 800 feet below the Pittsburg coal bed, the 

 increased interval being due chiefly to thickening of the Charleston 

 sandstone and the Upper Conemaugh. 



The identity of the Campbell Creek coal bed with that at Warfield, 

 Kentucky, seems to have been placed practically beyond doubt by 

 Doctor White's studies, thus fixing it at the Sharon horizon. A matter 

 of very curious interest is the presence of the lenticular limestones along 

 the Kanawha valley and in a so great area within Kentucky, while they 

 are absent or at least not reported from the intervening space in West 

 Virginia, except in one of Doctor White's sections. The Winnifrede 

 coal bed is evidently equivalent to Kentucky coal 3, the Splint of War- 

 field, the Peach Orchard and McHenry coals of Kentucky, representing 

 the Mercer horizon of Pennsylvania and Ohio. The Stockton is dis- 

 tinctly equivalent to Kentucky coal 6, which is at a little distance above 

 the Ferriferous limestone, and therefore the Lower Kittanning of Penn- 

 sylvania ; but the Stockton may embrace a higher bed and represent the 

 whole Kittanning horizon. This reference bears out the suggestion made 

 by Doctor White that the Stockton might prove to be Lower Kittanning 

 and not Upper Freeport, as has been the belief for almost one-third of a 

 century. The relation of the Coalburg is not wholly clear. To the 

 writer it appears to be most nearly at the horizon of Kentucky coal 4,
