In the above section the coal midway of the Barren Measures is prob- 
ably the Harlem seam, or 76. It will be noticed that there are two thin 
coals below this a few feet above the creek, then a seam three feet thick 
near the creek level. Sixty-two and a half. feet below this is another 
coal four feet thick, with a foot of limestone just beneath the fire-clay. 
Forty-one feet below this:again is a coal reported to be cannel, four feet 
thick, and fifty-seven feet below the ‘‘cannel coal” another seam five and 
one-half feet thick is said to have been passedthrough. When wecompare 
this Wills Creek section with those afforded by the shafts and “test 
well” at Steubenville, we find the task of co-ordinating them quite easy. 
The limestone coal (No. 35 of the Wills Creek section) is plainly the 
Shaft Coal of Steubenville. It is exposed in the bed of the Ohio, just 
above the mouth of Wills Creek; is reached at the depth of 75 feet in 
the shaft of Cable & Co.; at 80 feet in the Busted Shaft; at 172 feet in 
the boring in Stony Hollow; at 188 feet in the Rolling Mill Shaft; 204 
feet in Averick’s Shaft; at 221 feet in Boreland’s Shaft, and at 234 feet
