114 GEOLOGY OF OHIO. 



four seams of coal are seen, of which the lowest is No. 3, the highest 

 probably No. 6. Of the these, the latter has a thickness of four feet, 

 while forty feet below it is another coal, twenty-six inches thick, which 

 perhaps represents No. 5. 



At Harker's, on the north side of Liverpool, where most of the coal 

 used in the vicinity is obtained, the following section was taken : 



FT. IN. 



1. Slope, with old clay opening near top and sandstone at base 120 



2. Shale 5 to 10 



3. Coal, old opening fallen in (reported thickness) 2 6 



4. Interval, partly covered ; massive sandstone, twenty-five to thirty 



feet thick, ne^r the hase 50 



5. Coal 1 20 



6. Fire-clay, used for pottery - 8 



7. Interval ; gray shales above, massive sandstone, twenty to twenty- 



five feet thick, below 110 



8. Coal, thin. No. 4. (?) 



9. Fire-clay and shale, with nodules of calcareous iron ore 15 



W. CoalNo.3 1 



11. Hard, blue, sandy fire-clay 15 to 20 



12. Slope, with sandstone at base to river 45 



In Ellison's Hill, north of Liverpool, five seams of coal have been dis- 

 covered, which are probably the same with those opened in the Yellow 

 Creek valley, though the section presents some peculiarities in the inter- 

 vals which separate them. For example, above No. 3, which is only 

 eight inches in thickness, no coal is seen — though one may be present — 

 within a distance of fifty feet. At this level is a seam eighteen inches 

 thick ; sixty-five feet above it, another, twenty-five to twenty-seven 

 inches thick; sixty feet above this is a coal seam forty-five inches in 

 thickness, probably No. 6; and eighty feet above that lies another coal, 

 No. 7, (?) four feet thick. 



At N. A. Walker's pottery, on the west side of Liverpool, is a better 

 exposure ; and here the following series of strata are seen : 



FT. IN. 



1. Greenish shales, reported to contain a coal two feet thick, about 



one hundred feet above the next lower seam 40 



2. Sandstone , 85 



3. Grayshale 8 to 12 



4. Coal, worked, containing considerable sulphur 2 



5. Fire-clay 9 to 10 



6. Interval ; shale above, sandstone below 90 



7. Coal, local 2-4 



8. Fire-clay, local 3 o 



9. Sandstone 40
