where certainly recognized. In Vinton county, indeed, it has not been 
clearly identifi:d. There are several thin seams near its proper horizon. 
As to its identification with the Hatcher Coal, nothing need be added to 
the statements already made under the previous head. 
12. The next coal seam is one of Dr. Newberry’s main numbers in 
Kastern Ohio, viz.,Coal No. VII. It is a well-developed and well-known 
seam in the Hocking Valley, being here styled the Bayley’s Run Coal. 
Tt lies at eighty to one hundred feet above Coal No. VI, with an average 
elevation, say, of uinety feet. It takes its name from the Sunday Creek 
region, where its distance from No. VI is a little below eighty feet. It is 
shown in good force on Meeker’s Run, in York township, Athens county, 
onthe landof J. L Gill, Esq. It is here eighty-seven feet above the Nelson- 
ville Coal. It has a thickness of four feet, andagrees in character with the 
twoseams next belowit. It is held by many to be a coking coal and some 
good results have been obtained in this way, butit is doubtful whether it is 
rich enough in bituminous matter to make the process possible in the ordi- 
nary ovens. This latter test is always understood in claiming it as acok- 
ing coal. There is little doubt that the driest burning coals of our series 
‘can be coked by proper or possible management; but it seems improba- 
ble that any coal now known in the Hocking Valley will use its slack in 
the p:ocess of coking, in ovens of the ordinary type. There is no ex- 
tended seam, at any rate, of which this is true. The product of single 
mines may possibly give such a result. 
All through the southern counties, at one hundred to one hundred 
and twenty feet above Coal No. VI, a coal horizon is found, which is iden- 
tified in a general way with No. VII. It is not known to be worked except 
on the Monitor Furnace lands, opposite Ashland, Kentucky. The seam 
measures there three feet, and lies one hundred and two feet above the 
Sheridan coal. 
13. A coal seam that is nowhere very valuable, but that is as steady 
throughout a wide area as any other geological element, is next met 
with. It is named Coal No. VIla on the section. It lies about sixty or 
seventy feet above Coal No. VII. It seldom exceeds thirty inches in thick- 
ness, and is opened but infrequently. The coal is said to be of fair 
quality. Itis a northern seam principally. At least it has not been 
indentified south of the Hocking Valley, but this may result from a lack 
of sufficient work upon its proper horizon. 
14. Coal No. VIIb is, on the contrary, found only to the southward. 
Through Lawrence and Gallia counties a thin seam of coal is often found 
associated with the Cambridge Limestone. Lying well up in the Barren
