A shaft was subsequently sunk to the lower coal and it was found to 
be largely composed of slate and worthless. This stratum has been 
found in wells bored at McCoy’s Station, and it was supposed to be Coal 
No. 1. Whether it is really the representative of the Massillon coal can- 
not be determined, although this seems probable from the fact that it 
holds about the proper position for that seam, and no coal whatever was 
found below it. If, as reported by the drillers, the well passed through 
a conglomerate immediately below the coal, this would lend additional | 
probability to this theory. The nearest point to New Cumberland, 
where the Briar Hill coal has been struck, is at Limavyille, forty-five | 
miles north-west. The difference in level between the lower coals of the 
two localities is about 400 feet; the coal at Limaville being 409 feet 
above Lake Erie, while that at New Cumberland is just about the lake 
level. 
The limestone found beneath the ‘clay coal,’ at New Cumberland, is 
apparently identical with that which holds nearly the same position at 
Wellsville. It has not been met with in other sections in this region, 
and would seem to be a local deposit like several of those higher up in 
the series in different parts of Jefferson county. By Professor IJ. A. 
White, of the Pennsylvania Geological Survey, this is thought to be 
identical with the “ Ferriferous Limestone” of Rogers. If this is true, 
there is a great thickening of the Lower Coal Measures toward the east, 
for here this limestone is only about 125 feet above the lowest trace of 
coal found, and what is, for this region, the base of the series, whereas 
the Ferriferous Limestone isin Pennsylvania some 300 feet above the 
Conglomerate. There is very little doubt that the “Creek ” and “ Strip” 
veins of southern Columbiana county—which may be traced along the 
Ohio continuously from Liverpool to Sloan’s Station—are identical with | 
Coals Nos. 3 and 4 of the vicinity of New Lisbon, the first two workable 
coals above the Block coal—(No. 1) at Limaville and vicinity, and with 
the furnace coal and the next seam below it at Leetonia. Thatthey are 
identical with Coals Nos. 3 and 4, of the Tuscarawas Valley, cannot be 
demonstrated, as they have not been, and cannot be traced through the 
divide, but they hold the same relative position to the Barren Measures, 
and Coals Nos. 6 and 7 above, and to the base of the Coal Measures below. 
The flow of gas from the New Cumberland well has always been large,
