The limestone Kb. 14 of the above section, I belief to be the Quarry 

 creek bed of Clark county, and the distance between that bed and the 

 limestone of the Embarras, (Xo. 3 of the section,) which is here only 

 about 93 feet, while at Greenup it is 130 feet or more, shows the same 

 thinning out to the northward of the beds above the Quarry creek lime- 

 stoue, that was observed in Clark couuty in the strata below that rock. 

 Hence, the main coals, if found fully developed here, would be reached 

 at a depth somewhat less than in Cumberland. The total thickness of 

 the outcrops to be seen along the Embarras river, in this county, does 

 not exceed a hundred feet of Coal Measures, and includes the horizon 

 of coal No. 16 of the general section and the thin coal above it. Coal 

 No. 15 should be found underlaying nearly the whole of this county, 

 if it has not been cut out by denuding agencies. It is the thickest 

 of the upper seams, sometimes attaining a thickness of 2J to 3 feet. It 

 has been worked for many years in the vicinity of Shelbyvillein shafts 

 and inclined tunnels, and affords a semi-block coal of good quality. 



Economical Geology . 



Coal. — No outcrop of a coal bed thick enough to be worked to advan- 

 tage was found in the county, and unless No. 15 may be found beneath 

 the heavy drift deposits in the western part of the county, there is no 

 hope of obtaining an adequate supply of this indispensable article of 

 fuel without sinking to the main seams in the lower part of the Coal 

 Measures. A shaft from six to eight hundred feet in depth might reach 

 2STo. 7 or the Danville seam, but it would require one more than a thou- 

 sand feet deep to reach the bottom of the Coal Measures in any part 

 of this county. * 



Building Stone. — Sandstone of a fair quality for building purposes 

 may be obtained at various points along the bluffs of the Embarras 

 river, and the rock obtained from the quarries near the Westfield road 

 appears to be a durable stone, can be easily quarried, and has been very 

 generally used for the supply of the adjacent region. In the southern 

 portion of the county the rock is comparatively soft, and at the few
