WASHINGTON COUNTY. 497 
county is found further down the creek, and probably continues through 
Marietta township, it being, possibly, the seam found on the county 
infirmary farm. While there are, then, eastern and western dips, there 
is also the marked northerg dip already referred to. If we stand on 
the hill on the south side of Cow Run, in the center of the uplift, we 
find by leveling across to the north side, a distance of about a quarter of 
a mile, that the corresponding strata—the buff limestone, for example— 
are forty feet lower on the north than on the south side. Hence the 
axis of the arch of the uplift dips rapidly northward, and of course the 
arch soon flattens down and is lost in small undulations, generally too 
small to be easily detected. The arch also, doubtless, flattens down to 
the south, for on Hight-Mile Run, so far as I have examined, the anti- 
clinal is not very strongly marked, and all efforts to obtain oil there in 
any considerable quantity have failed. The following is a record of 
strata in a well—the Greenback well—bored by Messrs. Curtiss and Min- 
shall within the Cow Run uplift. The top of the well is about one 
hundred and forty feet below the Pomeroy seam of coal:

The oil has been chiefly derived from the two sandrocks, Nos. 7 and 11. 
The Newton well—the first one bored on Cow Run—obtained its oil from a 
fissure in the first sandrock, while many more recent wells extend down 
to the lower sandstone. The oil is found in fissures, and these fissures in 
our oil fields of Ohio and West Virginia are to be found along anticlinal 
lines. Not at all points within the uplift, or “break,” do we find oil. 
There are many dry wells where oil was most confidently expected. 
But generally, at Cow Run, while one is not sure in the most promising
