Joily town coal and Middle AY ashing ton limestone. —The Jolly- 
town coal bed is from 10 to 12 inches thick north of Buffalo Creek, 
but in the area to the south of this stream it seems to be represented 
by only a few inches of black friable shale. The heavy yellow bed 
of the Middle Washington limestone may be found from 72 to 78 
feet above the Washington coal at all points in the township where 
this horizon is exposed. The bed is not so prominent as it is in 
Hopewell and Independence townships, and in some places the top 
section seems to be wanting, though the heavy yellow bed character¬ 
istic of this member can always be found. 
Lower Washington limestone and Washing ton and Little Wash¬ 
ington coals. —The Washington coal and associated beds form the 
most prominent group outcropping in the township. They are char¬ 
acteristically exposed at the sharp bend in the road uphill west of 
Taylorstown. On the top of the hill 1 mile west of Taylorstown a 
ridge road branches northward to Buffalo Creek, on which this coal 
outcrops near its north end about 130 feet above the stream. The 
following section taken along this road gives a fair idea of the 
associated beds:
