Ft. In. 



6. Soft blue shale 25 



7. Shale, with strata of. black bituminous slate 75 



8. Coal, black slate, and fire-clay 10 



9. Hard sandrock, ''cap rock" 20 



10. Sandrock, believed to be the second oil sandrock of Cow Run 45 



11. Black slate 10 



12. Sandrock, a little oil in the lower part 45 



There is a large flow of brine from the sandrock No. 5, forced up from 

 three to four times a day by gas. The coal— No. 8 of the section — is one 

 of the lowest coals of the Coal Measures. Probably the two lower sand- 

 rocks belong to the Upper Waverly. It is remarkable that in the four 

 hundred and fifty-four feet above this coal no other seams should have 

 been found, for this space includes the proper geological horizons of some 

 of the most important seams of coal in the State — such as the Sheridan, 

 Nelsonville, Jackson Hill, and Anthony seams. It is evident from the 

 record of this well, and, indeed, from many other wells near the center 

 of our great coal basin, that seams so important along the western mar- 

 gin of the coal field have not extended to the middle of the field. The 

 conditions favorable to the growth and accumulation of the vegetable 

 materials for seams of coal appear not to have existed. 



On the hill back of Mr. O'Neal's farm we find, one hundred and thirty- 

 six feet above the Cambridge fossiliferous limestone, another body of 

 hard blue limestone, about six feet thick. This is the limestone seen in 

 the bed of Newell's Run, at the forks of the stream, near Basil William- 

 son's house. This limestone is ninety-eight feet below the Pomeroy 

 seam of coal, here associated with the buff limestone group. About forty 

 feet above the limestone, a little above Williamson's, on Newell's Run, 

 is a very thin seam of coal. We find traces of this seam in other coun- 

 ties. It is probably the equivalent of the Jeffers coal in Gallia county. 

 The center of the uplift is found a little east of Williamson's, on Kerr's 

 Run — a branch of Newell's Run — where the lower limestone is eighteen 

 feet above the bed of the run. There is here, therefore, a western dip. 



On the land of Samuel Kerr, on Kerr's Run, in section 5, we find the 

 Pomeroy seam of coal, with the ove: lying limestone group, in the bed of 

 the stream. A geological section taken here is as follows :
