Ashley, in the coal report on Greene County’, says: 
“Lower Carboniferous.—The Kaskaskia is well represented in this 
county by limestone and sandstone, with some shales. 
“The uppermost limestone, which is not very persistent here, usually 
is found but a few feet below Coal I or the equivalent horizon. This lime- 
stone, while often absent, attains a thickness of 20 feet in places. Then 
comes a variable thickness of sandstones and shales, and below that still 
heavier beds of limestone. The lower limit of the Kaskaskia is somewhat 
in doubt, as by some it is drawn at the top of this lower limestone, by others 
part way down it. The lower part of this limestone is probably of St. 
Louis age, and extends down into the Mitchell limestone.”

In the report on the road materials of Greene County, Blatchley says :* 
“TWuron Limestone—The rocks of the IIuron group lie close to the surface 
over the greater part of Greene County, east of White River. On the high- 
est ridges and hills they are capped with the Mansfield sandstone. For the 
most part the exposed Iluron rocks are also sandstone, but several localities 
there are outcrops of hard bluish Huron limestone, which appear well 
adapted for road improvement. 
“The principal one of these exposures visited was on the land of 
George Cox, southwest quarter of the northwest quarter of section 3 (7 N.., 
4 W.). At this point the Indianapolis Southern Railway Company was con- 
structing a viaduct 2,215 feet in length and 147 feet in height across Rich- 
land Creek, and a quarry had been opened to secure crushed rock for the 
concrete work in connection therewith. In this quarry the blue limestone 
was exposed in fourteen layers, each four to thirty inches in thickness, and 
aggregating seventeen feet. This limestone was both overlain and under- 
lain with a Huron sandstone, the overlying portion being three to seven
