summit of the highest ground; another is found about 4 mile west of 
the,town of Bedford. ‘The line of the outcrop of the coal runs nearly 
north and south and about 4 miles to the eastward of this line of out- 
liers. Passing into Washington township the line swerves to the east, 
and the lastgopening in No. 6 coal is found about 3 miles west of Adams’s 
Mills just inside the county line. 
No. 6 attains position as a mineable coal very soon after its first 
outcrop appears. Beginning in Clark township, where it enters the 
county from the north, its development will be noticed in each successive 
township southward. 
Clark Township.—The whole supply of fuel in this township is 
derived from the No. 6 coal. The mines are all situated in a group on 
the southern edge of the township. The hilly ground to the north- 
ward holds the veins, but in unpromising condition. The first good 
coal is found just south of Killbuck Creek, at Helmick. It is 
opened on the farms of Wm. Darr, Nich. J. Mullett, Joel Glover, 
Thomas Elliott and Samuel Felton. The coal is nearly uniform in 
appearance and quality; it is quite strongly coking; burns with 
the production of much tarry matter and the evolution of a good deal 
of gas, and makes a hot fire. It is high in sulphur and destructive 
to the linings of stoves. Its ash is a strong purple red color. Its 
thickness ranges from 30” to 42’, occurring in two benches, separated 
by 2” or 3” of clay or soft slate. |

Other sections are found in this vicinity, which show the Putnam 
Hill limestone at its normal level above the Lower Mercer, though it 
was concealed in this case. 
Bethlehem Township lies to the south of Clark and east of Jeffer- 
son. Across its southern and western borders the valleys of Killbuck 
and the Walhonding river have cut out all possibility of coals. No
