208 GEOLOGY OF OHIO. 
The records of the Wellsburg and Brilliant gas-wells that have 
been drilled within the last year will add to this series, if they are 
accepted, a 6 feet seam of coal that was reported as passed through 
about 450 feet beneath the Shaft seam. The value of the records 
depends on the care with which they were kept, and the discernment 
with which the work was followed. Without more knowledge than 
is now in our possession, it would not be safe to identify this seam 
as the Sharon coal of the general scale. It can, however, be said that 
the reported coal is just about where geology would locate this bottom 
seam, if required to find a place for it. The intervals would range as 
follows :

The good faith of the record is not questioned, but so anomalous 
are the facts reported that judgment may well be suspended until the 
claim shall be rendered more probable or less so by the rapidly accumu- 
lating facts of the same order. A basin of Block coal under the Free- 
port, and even under the Pittsburgh coals would be a fact without a 
parallel in our geology so far. 
In regard to the Lower Kittanning coal in Jefferson county, nothing 
needs to be added to the statements already made as to this seam in 
Columbiana county. All the facts and conditions reported there are 
exactly duplicated here. The clay is very extensively worked from 
Port Homer as far down the river as Toronto (Sloan’s Station), and 
the coal comes out to some extent with it, but it is never valued highly, 
nor would it often be sought on its own account. 
The Middle Kittanning coal (No. 4 of the Ohio Valley, and No. 6 
of the Tuscarawas Valley) has been worked at but a single point in 
the county to any considerable extent. It constitutes the Strip Vein 
NotrEe.—Since writing the above, Albert Smith, who is drilling the gas-well for the Jefferson Iron 
Works at Steubenville, has informed me that he kept close watch when passing this horizon, and 
found a considerable bed of black slate at a depth of about 650 feet, but not a particle of coal. He 
found no coal, in fact, below the Clarion horizon.
