The first of these tables shows a good deal of doubt as to the exact 
position of the top of the Salt sand and also of the Big Injun. The 
bottom of the Big Injun is more regular in position, being from 015 
to 545 feet above the Hundred-foot sand, the average being 532 feet. 
The second table, which gives the positions of various oil sands above 
and below the Ilundred-foot sand, shows the Berea to average 212 
feet above, the Thirty-foot 107 feet below, and the Gordon 205 feet

CHARTIERS TOWNSHIP, WASHINGTON COUNTY. 
Only a small portion of Chartiers Township is included in the 
Burgettstown quadrangle. This portion is in the southeast corner 
and is bordered on the north and west by Mount Pleasant I ownship. 
Members of the Washington formation. —The Waynesburg fcC A” 
coal shows as a good blossom fully as prominent as the Waynesburg 
bed. The Waynesburg “ B ” coal was identified by the limestone bed 
above it. 
Members of M onongahela formation. —The Pittsburg coal out¬ 
crops in the Chartiers Creek valley to a point half a mile above the 
junction of Westland Run. It continues in outcrop up Westland 
Run bevond the boundary of the township. The Redstone and 
Sewicklev coals both show as blossoms of 8 or 10 inches in thickness. 
They are easily found on the roads leading to the north and south 
from Chartiers Creek. The lower half of the Benwood limestone is 
well developed and prominent. Both the Dinsmore and Bulger lime¬ 
stones are prominent on all roads, the Bulger being resistant enough 
to form a terrace on the hillsides. The heavy blue bed near the 
top of the Benwood is also very thick and prominent. The Union- 
town and Waynesburg coals show only as blossoms a few inches thick 
and are hard to identify. 
Intervals. —In the small portion of Chartiers Township within the 
quadrangle the formations have so much dip that no good measure¬ 
ment of intervals could be made by comparing the elevation of
