Near Bloomfield several borings have been made for oil, but no records 
have been kept. Many persons agree, however, in the statement that a 
coal seam two and one-half feet thick was passed through at a depth of | 
about 180 feet, and another five feet thick at a depth of 260 feet. If the 
statement is true, these coals are doubtless Coals No. 7 and 6; the latter 
the Steubenville shaft coal. 
At Southfield Station the Pittsburgh coal does not appear immediately 
on the railroad, but is seen about one mile north, where we have the 
following section.

One mile east of the station and half a mile north of the road, on the 
farm of Mr. Davis, a coal seam two and one-half feet thick is opened. 
This lies above the sandstone seen at Shelley’s, and is probably Coal 78. 
Half a mile west of Gould’s Station Coal No. 8 outcrops, and has been 
worked 332 feet above the railroad. Another opening nearer the station - 
is 315 feet above the track. 
At Mingo Junction acoal seam twenty inches in thickness is seen 
about twenty feet above the top of the shaft. This is one of the small 
coals, 7a or 7b, which lie about midway of the Barren Measures. 
The following notes on the geology of the southern and western por- 
tions of the county have been furnished me by Prof. J. J. Stevenson: 
Warren Township.—In this township Coal No. 8 is available in the hill- 
sides on both Big and Little Short Creek, but owing to its altitude is 
opened at few localities. Near the junction of the two streams, it is two 
hundred and seventy-five feet above Short Creek, and at Portland it is 
nearly three hundred. The elevation above the stieam diminishes to- 
ward the western line of the township to about two hundred and ten feet. 
The hills are very steep, and the difficulty of constructing roads up their 
sides is so great that most persons prefer to obtain their coal from the few
