Although this boring commences above the horizon of No. 5 coal, 

 it was found to be too thin at this point to be of any practical 

 value, while the two lower seams penetrated in the bore were also 

 valueless. This barren area is not very extensive, as No. 5 out- 

 crops on Silver creek, about four miles a little east of north from 

 Lementon, with its normal thickness of five to six feet. Probably 

 a boring two or three miles east of this point would result in find- 

 ing this seam of coal with its average thickness, and at less than a 

 hundred feet from the surface. 



The following is a record of a boring made at Chapin, on the 

 county line between Scott and Cass counties :

A shaft was sunk to the first cdal, No. 12 of the record, but it 

 proved to be an unproductive seam, and the experiment was soon
