These vary in thickness from 3 to 5J feet, and in general show a 
fair correspondence, though the agreement is not so close as in 
the Pigeon Creek district. All the sections contain a main bencl 
of 24 to 38 inches and with one exception have above the main 
fire-clay parting a roof coal reaching a maximum thickness of 2"2 
inches, hut averaging about 10 inches. In one case the sandstone 
roof rests directly on the main bench (section 45). The bottom coal 
is separated from the main bench by 1 to 4 inches of fire clay. In 
three cases the main bench is divided by a knife edge to 2 inches oi 
hone or shale (sections 40, 44, and 48). As a rule the roof is sand- 
stone, but locally it is shale and in some places fire clay. In the last 
case the day is only 6 to 18 inches thick, and directly above it tlie 
sandstone is present, as usual. The main fire-clay parting thickens 
up here and there, as shown in Horn's bank (section 49), to 3 or 4 
feet. In this section the "roof coal" is bony. The other section oi 
Horn's bank (section 48) is more nearly the average. 
On Little Tenmile Creek at the village of Lone Pine the Amity anti- 
cline brings the coal above stream level for about a mile, and it is 
worked at a number of country banks. The sections measured here 
show great uniformity (sections 52 to 58), and may therefore be 
taken as average for the Waynesburg coal in this region. Details 
are given in the next table.
