Bed of Kerr's Eun. (This is the upper part of section No. 29, Map XI.) 



At this point we are well on the eastern slope of the uplift. From a 

 point three-eighths of a mile below, on the stream, it was found that the 

 dip in this distance was one hundred and two feet. This is not the 

 measure of the greatest dip, for the valley here runs in a north-west and 

 south-east direction. 



On ascending a branch west from Williamson's the western dip is 

 very marked. This is seen on the land of H. Pegg. Besides the eastern 

 and western slopes of the uplift, we find, as at Cow run, that the top of 

 the anticlinal arch gradually sinks down and dies away to the north- 

 ward. Near the center of the uplift, on the Ohio, the same limestone 

 which is seen eighteen feet above the bed of Kerr's Run, also near the cen- 

 ter of the uplift, is two hundred and two feet above the water of the Ohio. 

 It is probably not more than a mile in a straight line. If we allow 

 eighty feet for the fall of Kerr's Branch and Ne well's Run, we have one 

 hundred and twenty-two feet of northern dip. North of Williamson's, 

 as we ascend Newell's Run, the dip of the strata to the north was ascer- 

 tained to be proximately one hundred and twelve feet per mile. This 

 carries the Pomeroy coal, with its associated limestone group, below the 

 stream, and higher up the Cumberland seam under the heavy sandrock 

 goes under. The latter coal has been opened and mined a little. It 

 measures twenty-one inches in thickness. Higher in the hills, at the 

 head of the run, is the Hobson seam of coal, the place of which is ninety 

 to one hundred feet above the Cumberland seam. 



The axis of the Cow Run uplift in Lawrence, if produced south, would 

 be about three and a half miles west of the center of the Newell's Run 

 uplift. Wells bored for oil in Newport have not generally been successful. 

 The anticlina arch is so broad and flat that it is very difficult to deter- 

 mine beforehand just where the largest subterranean Assuring of the 

 rocks may be. Wells have been bored in the center and on either slope, 

 some of them very deep, but no large reservoirs of oil have been struck. 

 At some points in West Virginia, by a careful study of the "break," as it 

 is called, I was enabled to predict, upon the position of the rocks on the 

 surface, where the large oil fissures must almost necessarily be found, and 

 these predictions were abundantly verified. But in Newport the same 

 "break," or uplift, so flattens and fades away that I have found it impos-
