of 1,932 feet, and though only five feet thick contained much gas, the closed 
pressure being reported at 440 pounds. The fuel was used in developing 
the surrounding territory, and the well is still producing. The discovery 
of large supplies of gas made operating much easier, and drilling pro- 
eressed rapidly. The limits of the field appear to be now pretty definitely 
determined, though doubtless a fair number of producers will yet be 
secured. In 1gor the Berea sand was tested, 3 wells having been sunk 
on the Stephens farm. The best well produced 20 barrels of oil the first 
day and one the next. All were soon abandoned. From well No. 28 on 
this farm the following data were taken:

Geology of the Field.—This is of interest since it lies on the Burning 
Springs anticlinal which crosses the Ohio near the mouth of Newell’s Run, 
and is known on this side of the river as the Newell’s run uplift. The arch 
must be given high rank among structures of this kind in Ohio. Its mag- 
nitude is shown by the fact that at Eureka, West Virginia, the Berea is 
found at a depth of 1,350 feet, while 4 miles southwest on the Palmer farm, 
a well drilled on the river bank at practically the same surface altitude 
found the sand 1,950 feet below the surface, showing a fall of 600 feet in 
that distance. Passing eastward the same conditions hold, only the crest 
of the arch having been crossed the strata dip to the east. Thus a little 
more than one mile east from the mouth of Newell’s run, the wells on the 
Ohio side of the river strike the Berea at approximately 1,600 feet; while 
at St. Mary’s, West Virginia, 3 miles east frony Newell’s run, the forma- 
tion lies 1,900 feet below the surface. 
The arch has long been known. It appears to have been described 
for the first time by Prof. E. B. Andrews in the American Journal of 
Science for July, 1861, and subsequent reference is made to it by the 
same writer in his report on the Geology of Washington county published 
in 1874.2 According to this geologist the arch crosses the river near the 
mouth of Conley run, which unites with the Ohio nearly 2 miles above 
Eureka. Hence, the Berea should be found there at a smaller depth than 
at Eureka. The First Cow Run sand is placed 200 feet below the surface in , 
the Eureka well by Professor White, while according to Andrews it is 
actually above drainage at the mouth of Conley run. According to this 
the Berea should be found at a depth of not more than 1,150 feet at the 
latter place. The dip, then, between this point and St. Marys, 3 miles
