above New Salisbury. Between this point and Salineville the coal seams 

 are not well shown, and have been very little worked; as a consequence, 

 some confusion has been produced in the minds of the inhabitants of the 

 valley in regard to their identity. Comparing the sections which we 

 have taken at dififerent points on the creek, and which I now place side 

 by side, it would seem that there was no just cause for the difficulty 

 which has been experienced in identifying the Salineville coals with 

 those which have been ^numerated as occurring at points lower down on 

 the stream. 



At Salineville the strata rapidly rise toward the north and west. 

 Three coal seams are exposed here — the upper, called the Strip, the 

 next the Big, and the third the Creek Vein. 



Over the upper or Strip Vein lies a mass, nearly three hundred feet 

 in thickness, of red and greenish shales, with beds of sandstone, which 

 no one wiLl fail to recognize as a portion of the Barren Measures. This 

 is further proven by the presence, at a distance of about two hundred 

 and fifty feet above the Strip Vein, of the Crinoidal limestone, one of 

 the most reliable guides in the entire coal series. 



Under the Strip Vein at Salineville, as at Linton, we also find a bed of 

 impure limestone, which is quite persistent. 



T'rom fifty to sixty feet below the Strip Vein lies the Big Vein of the 

 Salineville series, varying from five to seven feet in thickness; and 

 about forty feet below this another coal seam, under which is another bed 

 of limestone. 



By comp iring this section with that taken at Irondale or Linton, no 

 one will fail to be convinced that, with the common horizon of the Bar- 

 ren Measures and Crinoidal limestones above, we have in the Strip Vein 

 of Salineville, the Groff Vein of Linton (or, in other words. Coal No. 7)' 

 and in the Big Vein of Salineville, the Big Vein of the lower portion of 

 the valley; still further, that in the coal seam which lies below the grade 

 at Salineville Station, but which comes out at the old gas well, we have 

 the representative of the Roger Vein, or Coal No. 5, with its characteris- ' 

 tic limestone under it. 



Going north from Salineville, the railroad rises with great rapidity, 

 but for some distance above town the Strip Vein (Coal No. 7) is visible 

 in many localities along the side of the track, and seems to be dipping 

 with the grade. It is here quite extensively mined by the Hartford Coal 

 Company, and is often referred to as the Hartford seam. In the upper 

 portion of the valley of Yellow Creek the relations of the strata are seen 

 more distinctly than on the railroad.
