Art. XLV.—On the Oil-producing Uplift of West Virginia; by 
Prof. KE. W. Evans, 
THE most productive oil region of West Virginia, so far as 
developments have yet gone, is ; confined to a line of uplift, ex- 
tending from Burning Springs on the Little rye: in a di- 
pele from twelve to fourteen degrees east of n rth, to the 
Ohio river,—a distance of 35 miles. Thus iinited. the line is 
ally. bisected by the Northwestern Virginia railroad, at Petro- 
pn soe which will therefore serve as a convenient point 
of refe 
In its central portion, which for convenience I shall wei sts 
as the middle segment, the upheaval is most marked, an 
hibits some pipes features. This part is about ten mails in 
length, arid is also nearly bisected by the railroad. A cross- 
section of it, as ands out from the railroad cuttings, the records 
of borings, and the frequent exposures of rock along the streams 
of the neighborhood, is shown in fig. 1, It is a decapitated
