ever, been opened on itsouterop. It underlies the surface of Wabash 
County at a moderate depth from a point north of Friendsville south- 
ward to Bellmont and Keensburgaud westward to the bottom land of 
Bonpas Creek. No coal which could be correlated with the Friends- 
ville bed has been recorded in the wells near Bonpas Creek, with the 
possible exception of one point southwest of Cowling. It has not been 
found in Edwards County. Neither has it been recognized at Mount 
Carmel nor southward along the Wabash River above Rochester, 
and there is every evidence that it has pinched out and disappeared. 
A deep drilling at Grayville, made expressly for information regard- 
ing coals, failed to find any over a few inches in thickness, indicating 
that the Friendsville vein has disappeared to the southwest as well as 
to the west and east. 
The Friendsville coal maintains rather persistently an av T erage 
thickness of about 3 feet. It is mined by shafts 1 mile east of Friends- 
ville, 2 miles southeast of Friendsville, 1| miles south of Bellmont, and 
at McClearys Bluff, on the Wabash River. It has been mined in the 
past at Sugar Creek, Maud, and at several points northwest of Mount 
Carmel. The coal burns moderately freely, but has a large ash con- 
stituent and does not coke. 
The dips of the Friendsville coal are more irregular in character 
but less in amount than those exhibited by the coals in Indiana. The 
general dip, however, is still to the west. The highest altitudes at 
which the coal occurs is from 450 to 460 feet, these altitudes being 
reached at a number of points between Mount Carmel and Friends- 
ville. East of Friendsville the altitude of the coal declines to 400 feet 
or less near Crawfish Creek, while to the west, southwest, and south 
the gentler but more persistent dip carries it downward to an altitude 
of about 350 feet in the vicinity of Cards Point, 385 feet at Maud, 395 
feet at Bellmont, 360 feet at Keensburg, 370 feet at Rochester, and 
335 feet 1^ miles southwest of Cowling.
