of Tenmile Creek can probably be taken out better from a somewhat 
deeper shaft sunk near the head oi Patterson Run or on Craig Run or 
Craynes Run in Greene County. Most of the coal in the borough of 
Deemston can be mined from shafts which will doubtless be sunk on 
Plum Run, along which the depth of the coal varies from 190 feet at 
the mouth of the run to 430 feet near its head. Below Plum Run oh 
Tenmile Creek the coal approaches the surface. It is probable that 
the eastern part of the borough of Deemston can be best developed 
from the heads of the valleys in the vicinity of Deemston. The depth 
of shaft necessary in the two valleys west of Deemston will be about 
350 feet and on Fishpot Run east of Deemston 250 to 300 feet, accord- 
ing to exact location. 
In the southwestern quarter of the quadrangle almost any point 
along Tenmile or Little Tenmile Creek or their larger tributaries is 
suitable for shafl locations, but no shaft should be sunk within a mile 
or so of the point where the Amity anticline crosses Tenmile Creek l\ 
miles east of Hackneys. Along this creek between Bissell and Hack- 
neys the coal will probably be reached between 440 and 480 feet below 
the surface; and mining can be conducted with good drainage in ever! 
direction except toward the south. The area south of the creek can 
probably be best developed by working northward from near the 
heads of Craynes and Boyd runs and Ruff Creek in Greene County, 
thus working up the dip. 
On Bane Creek the coal descends from 450 feet below the surface at 
its mouth to about 720 feet in the bottom of the Nineveh syncline near 
McCracken station. Between Hackneys and Sunset workings can be 
carried east of the creek to the limit of a profitable haul, but as the 
strike here is about parallel to the creek, the area west of the creek 
should be mined from shafts situated farther west, in some of the side 
valleys. Above Sunset the strike of the rocks is more nearly at right 
angles to the creek and hence mining can be conducted both east and 
west of the creek in this part of the area. A shaft about 700 feet deep 
sunk on the axis of the syncline near McCracken could mine in all 
directions with every advantage. By referring to the map it will be 
seen that the Waynesburg and Washington Railroad follows Bane 
Creek northward from Hackneys to its source and thence climbs over 
the hills to Washington. This railroad is a narrow-gage line with 
steep grades and hence can not now be used for hauling coal ; but if it 
should be rebuilt on a broad gage and connected with, the Mononga- 
hela Valley by way of Tenmile Creek, it would furnish an outlet for the 
coal in this region. 
On Little Tenmile Creek the coal is nearest the surface near Lone 
Pine, where its depth is about 330 feet. From this point the bed 
descends in both directions to about 470 feet below the surface at the
