It is reported thai along Little Chartiers Creek, on the boundary 
between South Strabane and Somerset townships, the Washington 
coal was once opened and had a thickness of 2 feet 6 inches. In 
numerous places on the ridge separating North Strabane and Not- 
tingham townships it amounts to several feet. Stevenson reports a 
thicknessof 2 feel 7incheson Tenmile Creek ° in Am well Township, hut 
it is here separated into three benches by two thick fire-clay parting! 
(fig. 6, No. L5). In West Bethlehem Township, H miles above 
Zollarsville, 6 it measures in all 3 feet 3 inches, but 11 inches of this 
is clay (fig. 6, No. L6). At Tenmile village 3 feet 6 inches is 
reported, containing two lire-clay partings, 5 and 6 inches in thickness 
(sec fig. 6, No. 17). 
In the vicinity of Dunn station and West Amity the coal is recorded 
in a number of wells. On Little Daniels Run, 2 miles southwest of 
Scenery Hill, it was once opened and is reported 20 inches thick. 
QUALITY. 
Usually where the Washington coal has been seen in the quadrangle, 
it is made up of many alternating layers of coal and shale and is in 
genera] a very inferior coal. In neighboring districts, however, it is 
frequently found of fair quality, sometimes equaling the Waynesburg 
bed in value. No analyses have been made of the Washington coal 
in this quadrangle, but the following analyses from banks near Tay- 
lorstown, Washington County, and Ryerson Station, Greene County, 
arc given to show the composition of the Washington coal when at 
its best:
