60 GEOLOGY OF OHIO. 
The Lower Freeport coal is here, as everywhere else throughout 
this region, a little more than 300 ft. below the Crinoidal limestone. 
The distance in this measurement is 331 ft. On Island Creek it was 
found to be 336 ft. On King’s Creek, on the other side of the river, 
it is 308 ft. The coal makes one more appearance in the main valley 
before it dips below the surface. Just above the mouth of the creek, it 
is found level with the river at low water. 
From this point on, Newberry’s account of it is clear and succinct. 
In vol. III, page 756, he says, ‘‘the limestone coal of the W:lls Creek 
section” (the Lower Freeport of our last section) “is plainly the shaft 
coal of Steubenville. It is exposed in the bed of the Ohio just above 
the mouth of the Wills Cieek ; is reached at the depth of 75 feet in the - 
shaft of Cable and Co. ; at 80 feet in the Bustard shaft; at 172 feet in 
the boring at Stony Hollow; at 188 feet in the rolling mill shaft; at 
204 feet in Averick’s shaft ; at 221 feet in Boreland’s shaft, and 234 
feet at the Mingo shaft. At Mingo, Borelands and the Bustard shaft, a 
band of nodular limestone was found just below the fire-clay, as in the 
Wills Creek boring.” But furthermore we find in the relations of the 
Crinoidal limestone, confirmatory proof of the conclusion just reached 
that the Steubenville shaft coal is the Lower Freeport or Roger seam. 
This persistent stratum is found directly above each of the following 
named shafts at Steubenville, viz., Alicanna shaft, Stony Hollow shaft, 
and Market Street shaft. In the first the interval between the shaft 
coal and the Crinoidal limestone is 313 feet, in the second, it is 326, and 
in the third it is 330 feet. Gathering up all the measures that we have 
thus far found of the interval in question, we obtain the following series. 
A second column shows the interval between the Clay Vein and the 
limestone :
