gradually undermined and accumulated here. The ores shows the im- 

 pressions of fern leaves and other vegetable tissues by which it is so 

 widely characterized. A thickness of shale and fire-clay varying from 

 two to ten feet underlies the great coal seam. 



The coal has a thickness of six feet and eleven inches. It has the 

 usual partings and is, in every respect, an excellent representative of the 

 great seam in its best estate. It is overlain by a few feet of shale which 

 is in turn succeeded by a sandstone ledge about twenty feet in thickness. 



Coal No. Via, with a thickness of three feet is next met with, at a 

 height of twenty-eight feet above the great seam. It is a coal of fair 

 quality and would attract attention in many other fields. Its steadiness 

 cannot be relied upon. 



The Lower Buff Limestone and its associated ore are found at an eleva- 

 tion of forty three feet above Coil No. VI. They are styled in the section 

 the Moxahali. lime and ore, but in the body of the report they have 

 been connected in name with the coal seam above them, viz., the Norris 

 Coal, and have been described as the Norris Lime and Ore. The latter 

 name is to be preferred. There are twelve inches of limestone and six of 

 ore in the openings shown. 



The very variable and inconstant seam known in this report as 

 Coal VI6, is found at an elevation of foity-nine feet above the base. The 

 seam is here but one foot thick. Three miles north-east, on the Lefever 

 farm of W. W. Poston, Esq., the same seam has a thickness of over five 

 feet. 



The Shawnee or Buff Limestone holds its usual place at sixty-five feet 

 above the Ntlsonville Coal. It is thirty inches thick in the section here 

 shown, and twelve inches of the ore that accompanies or replaces the 

 limestone is shown above it. The ore seems to have the usual character 

 of the Straitsville seam. 



This is one of the few sections of this region that distinctly shows the 

 Bucbtel ore in its relations to the other elements of the section. Fifteen 

 inches tf ore of fair quality are shown ten feet above the limestone last 

 named. 



Another ascent of ten feet brings us to Coal No. VII, or the Bayley's 

 Eun Coal. There is a fine showing of this seam, four feet in thickness, in 

 the section under review. The coal has all the best characters of this seam 

 in this vicinity. Like the two coals next below it in the section, it is 

 much more bituminous and melting than the great seam. Whether it will 

 prove a valuable coking coal remains tobd demonstrated, the experiments 

 thus far made not having complied with all the necessary conditions. 



Eighteen feet above Coal No. VII a stratified ore, two feet and one inch
