marked, that there is great confusion among our geologists rela- 
of coal at Athens, Ohio. My own investigations 
to believe the Wheeling and Pomeroy seams to be entirely dis- 
tinct, while the Athens coal is probably the continuation of the 
omeroy seam. The Athens coal is probably the same with the 
‘ Coal, (Athens Co.) which, by all our Ohio geolo- 
gisis, is regarded as the continuation of the Pomeroy seam. The 
omeroy seam, as traced by myself, from Federal Creek into the 
northwestern part of Washington County, is found to be from 
Sixty to seventy feet above the very limestone group which is 
80 persistent, and which carries with it the Coal Run and Wheel- 
Federal Creek 
heeling, and Pomeroy 
ave 
everywhere from fifty to seventy feet above the limestone group. 
Doubtless the seam of coal which is found in the hills above the 
heeling seam at Belleair (near Wheeling), is the equivalent of 
the Pomeroy coal. 
’ 
he Bear Creek coal, which I propose to examine, is without 
e 
doubt th 
e geological equivalent of the Pomeroy s 
1owever, greatly modified in structure b

which I shall 
hereafter explain. Before the Bear Creek coal disappears to the 
south, there is evidence of a struggle in that direction between the 
vegetation and the water. The coal-marsh was repeatedly flood-
