502 GEOLOGY OF OHIO. 



on the Newport side is at or very near the mouth of a little tributary 

 of the Ohio called Conley's Run. This is a little above the mouth of New- 

 ell's Run. In the immediate bank of the Ohio we find by far the lowest 

 rocks, geologically considered, in the county, for the bottom of this up- 

 lift is, geologically, about one hundred and sixty-five feet lower than the 

 bottom of the Cow Run uplift. The sandrock in which the old Newton 

 well, on Cow Run, found its oil, is here seen in the Ohio River bank. 

 The following section gives the lower strata near the mouth of Conley's 

 Run: 



Ft. In. 



1. Fossiliferous limestone 1 6 



2. Yellow shales 18 



3. Slaty coal 8 



4. Clay and coal 6 



5. Fire-clay, light-colored 6 



6. Coal • 6 



7. Not exposed 20 



8. Sandrock, with some quartz pebbles, first oil rock of Cow Run 25 



9. Iron ore adhering to sandrock 6 



10. Blue clay shale, with nodules of iron ore 1 6 



Level of water Ohio River. (This is the lower part of section No. 29, Map XL) 



The limestone No. 1 of this section is doubtless the equivalent of the 

 Cambridge fossiliferous limestone, which is seen in many counties, and 

 has its place about two hundred and thirty feet below the horizon of the 

 Pomeroy seam of coal. I have observed it nowhere else in Washington 

 county ; indeed, at no other point could we expect to find it except in 

 the Ne well's Run uplift. The thin coal found eighteen feet below this 

 limestone is found in other counties, always holding the same relation 

 to the Cambridge limestone. It is always thin, and of no practical value. 

 There is often a thin seam of coal a few feet above the limestone, but it 

 was not seen in the uplift. No very good exposures of the strata imme- 

 diately above the limestone, however, were seen, and no careful search 

 was made for it. It was not reported as passed through in the Cow Run 

 wells, while the seam eighteen feet below was found in its true place. On 

 the farm of Mr. Joseph O'Neal, between Conley's Run and the mouth of 

 Newell's Run, a well was bored by F. W. Minshall, Esq., the top of the 

 well being four feet below the Cambridge limestone. The following is 

 a record of the strata passed through : 



Ft. In. 



1. Sandstone 15 



2. Coal, etc - 1 6 



3. Sandrock, believed to be the first oil rock of Cow Run 44 



4 Red and blue shales 210 



5. White sandrock, with a strong flow of brine from near the bottom. .100
