JEFFERSON COUNTY. 761 
In sinking the La Grange shaft three thin seams of coal were cut. Of 
these two are twenty-two feet above the shaft seam, respectively seven 
and fifteen inches thick, separated by two feet of sandstone. These are 
regarded by Mr. Andrew Roy, State Inspector of Mines (report for 1876, 
p. 172) as the equivalent of the Mingo and Steubenville shaft coals, and 
as Coal No. 7, while the shaft coal of La Grange and Rush Run he con- 
siders the representative of the coal found forty-four feet below the main 
seam in the rolling-mill shaft at Steubenville, and this as Coal No. 6. 
For reasons given elsewhere, | am compelled to dissent from this opin- 
ion. In my judgment Coal No. 7 runs out just above Steubenville. The 
Shaft Coal at Steubenville, Mingo, and Rush Run is all the same seam, 
and Coal No. 6. The lowest coal in the Rolling Mill Shaft is probably 
Coal No. 5.* 
. The Pittsburgh seam, at La Grange, is about five feet thick, with a 
parting of slate, sometimes two, near middle. The coal works in large 
cubical blocks, resembling that mined at Pittsburgh in appearance and 
character, though containing a little more sulphur. An analysis of it 
will be found in the table at the end of the chapter. 
RUSH RUN. 
At Rush Run the Steubenville Shaft Coal has attained extraordinary 
dimensions, in some places being nine feet in thickness. It is, however, 
generally less, being but two feet thick in the highest part of the mine, 
and the average thickness would not be greater than seven to eight feet. 
The coal is divided by partings, and is less uniform in quality than the 
Steubenville coal. Some portions of the seam, however, closely resemble 
it, and there can be no reasonable doubt that they are geologically the 
same. We have reason to believe, also, that the Rush Run coal is the 
same with the Great Vein of the Hocking Valley region. This cannot 
be demonstrated because throughout all the interval between these two 
localities all the lower coal group are deeply buried, but the Rush Run 
and Hocking Valley coals hold the same relative position to the Pitts- 
burgh coal and the crinoidal limestone, which may be and have been 
traced through. The shaft by which the Rush Run coal is reached is 
255 feet deep to the coal. It is owned by Messrs. Peck & Ramsay, who 
have now for several years carried on extensive and successful coal 
business. 
* T am informed by Mr. Lowe that in a boring on Panther Run, about three miles 
south-east of La Grange, on the West Virginia side of the Ohio, the shaft coal was 
struck at a depth of 347 feet from the surface, and that 29 feet above high-water mark 
in the Ohio. The coal is there six feet ten inches in thickness. Two small seams were 
passed above it, one 160, the other 210 feet from the surface.
