In the above section the coals are apparently the same with those 

 opened at Wells's mine, the distance between them being here seventy-two 

 feet, and fifty-four feet there. The lower coal in the above section has 

 not been worked to any extent. It is reported poor. The "Finley Coal," 

 or No. 7, at Moreland's, has the following composition : 



1. Black shale. 



2. Slaty coal 18 inches. 



3. Coal 30 " 



4. Slate parting 1^ " 



5. Coal 18 " 



6. Fire-clay. 



Nearly a mile further up Island Creek, this coal has been opened on the 

 farm of Mr. H. F. Fleming, three and a half to four feet thick, and of good 

 quality, though, as shown by analyses, inferior to the Steubenville coal. 



In the highlands back of the river the Pittsburgh seam is found in 

 many localities from Knoxville south. It is quite largely worked for 

 home use, but it lies at a distance from the railroad, and the coal it fur- 

 nishes is of fair but not superior quality. It cannot, therefore, be profit- 

 ably shipped. 



Knoxville is built upon a higher hill than any in the neighborhood. 

 Several seams of buflf limestone occur on the hill, and the Pittsburgh 

 coal lies one hundred and eighty-five feet from the top. It is here four" 

 feet thick, and is mined on the farm of Mr. T. S. Mills. 



Coal No. 8 also occurs in some of the high hills between Knoxville 

 and McCoy's Station, and towards the south and west it is found on all 

 the land which is high enough to catch it. It is mined in many places 

 near Pekin and Richmond. 



The following section was taken from Knoxville south to Island Creek. 

 The heights were measured by barometer in bad weather, and are there- 

 fore not to be relied upon. For example: the distance between Coal 

 No. 8 and the crinoidal limestone, which is elsewhere in this region 

 about two hundred feet, as shown by the barometer, is, according to the 

 series of observations, only one hundred and sixty-two feet :
