JEFFERSON COUNTY. W31 
forty feet below it No.5 appears. About ninety feet above a coal out- 
crop is seen, which probably indicates the place of No. 7. Still higher 
are the crinoidal limestone and the Harlem éoal. 
At Moretown three coal seams are seen, apparently the same as those 
exposed at the Tunnel Mill. At Dorrance’s the lowest is three feet 
thick, with much sulphur, and bearing a strong resemblance to the 
Roger vein. The next seam is fifty feet higher, and four feet thick, 
netting over three feet of good coal. The loss is occasioned by a slaty 
band at the top, a feature this coal has in common with the “ Big Vein” 
at Salineville, its probable equivalent. It contains, however, less sul- 
phur here than is usually found in the “Big Vein.” The upper seam, 
sixty feet above the one last mentioned, is said to be twenty-eight inches 
thick. 
At Nebo, the lower of the three seams mentioned is seen near the 
tevel of the creek, and one mile west of this point it passes beneath it 
and disappears. The upper two of the thin coals exposed below appa- 
rently continue to the county line, but are shown only by outcrops. A 
bed of light gray limestone appears midway between the lowest and 
‘middle seam. 
In the Barren Coal Measures which form the hills westof the county 
line, the crinoidal limestone is conspicuously shown, with its associated 
strata, giving the following section :

In the valley of Big Yellow Creek no Drift was found on the surface, 
but a few transported bowlders were seen at a farmer’s house, and are 
said to have come from the bed of the creek. These were probably brought 
down by some tributary of this stream reaching to the margin of the 
Drift area. 
A few observations on the directions of the joints in the coal of this 
region, made by Mr. G. K. Gilbert, give the following results: Two miles 
below Salineville the main cleavage planes are N. 60° E.; at New Salis- 
bury and Irondale, N. and S.; on Big Yellow Creek, near Brush Creek, 
N. 50° E.
