oil going to Toledo, Findlay, Newberg and Cleveland. It entered the field 
in December, 1&9, and began shipping the following month. The quan- 
tity shipped has ranged from 3,000 to 6,000 barrels per month. In 1899 
a small refinery was built at Scio, and is reported to have used about 100 
barrels per day. It was short lived, however, for in 1901 the Standard 
Oil Company secured control of it, and since then it has been quiet. 
Geology of the Field.—The surface rocks lie in the Conemaugh for- 
mation or Lower Barren Coal Measures, the Upper Freeport coal passing 
below drainage a few miles to the west, while the Pittsburg coal appears 
in the hill tops a short distance beyond the eastern limit of the pool. 
Conotton Creek, flowing in a northwesterly direction and having a broad 
valley, divides the field into two nearly equal parts. Through this valley 
the two railroads run and the village is built on it. The topography of the 
field is rough. ‘The succession of strata below drainage is shown by the

The coal seam reported at a depth of 185 feet is probably the Upper 
Freeport. The sand rock lying 20 feet higher cannot be the Cow Run 
as named by the driller since the interval between the two should be about 
100 feet. The Salt sand ranges in thickness from 40 to 75 feet, and 
usually contains a large quantity of brackish water, but is sometimes dry.
