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 Steuben ville 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 mam 

 seam in the rolling-mill shaft at Steubenville, and this as Coal No. 6. 

 For reasons given elsewhere, I 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 EUN. 



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. 



" I am informed by Mr. Lowe that in a boring on Panther Run, abont 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.
