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 different 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 enumerated 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 wiil 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. | 
From 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 comparing 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. OD) 
and in the Big Vein of Salineville, the Big Vein of the lower portion at 
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 ca 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.
