120 GEOLOGT OF OHIO. 



The Valley of North Fork.- — In the region about Achor nearly all the coal 

 Beams -which have been referred to in the preceding notes are exposed 

 and worked. They here attain good thickness, and are generally of ex- 

 cellent quality. 



At the mine of Isaac Dyke, on Camp Run, Coal No. 6 has been worked 

 for some years. It is here from three feet nine inches to four f^et six 

 inches in thickness, and very good. Beneath it is a stratum of fire- clay, 

 which rests upon the White or Freeport limestone. About twenty-five 

 feet below No. 6 is Coal No. 5, h«re about two feet in thickness, and not 

 worked. At a lower interval in the bed of Camp Run Mr. Dyke reports 

 a heavy bed of coarse cannel. 



Coal No. 6 is also worked about Achor by William and John Burt, 

 George Burson, and Mr. Boerum, all in section 15 of Middleton township. 

 On section 5 it is worked by Hiram Burt, Madison Wherry, and the heirs 

 of W. J. Billingsly ; on section 1, b.y Mark Burt; section 12, by Isaac 

 Booth; section 11, by Jane Nevin; section 22, by Isaac Dyke, Eli Guy, 

 Ephraim Latta, and Thomas George ; section 14, by John Young ; section 

 13, by Jeremiah Booth. 



Coal No. 7 is not worked in the immediate vicinity of Achor, but it is 

 visible in the tops of many of the hills, and has been opened on the land 

 of J. W. Billingsly in section 10. 



In several places about Achor a heavy bed of cannel comes in below 

 Coal No. 6. This is well exposed on the lands of P. T. Brown, on what 

 is culled Bald Knob, in section 11; also on the lands of J. W. Billingsly, 

 leased by Mr. Brown, in section 10, and on the farm of W.-Eddings, in 

 Bection 36 of Middleton township. 



The cannel coal of Bald Knob has been carefully examined by Professor 

 B. Silliman, jr., who has published a detailed report upon it. I give below 

 three analyses of this coal made by Professor Silliman. From these it 

 will be seen that it is of about the character and value of the Darlington 

 cannel, now so extensively mined and shipped to the eastern markets.

An analysis of another specimen from the same locality will be found 

 in the table at the end of this chapter. 



The relative position of this cannel coal will be seen at a glance by the 

 following section taken on the land of J. W. Billingsly:
