CUMBERLAND, COLES AND DOUGLAS COUNTIES. 99 



Shelbyville coal of Shelby county, making an aggregate thickness of 

 200 to 250 feet. Not more than one-half of these beds are exposed in 

 the county, and we have to rely on the borings made at Greenup, and a 

 general acquaintance with the outcrops in adjoining counties, for a full 

 description of the strata. 



The following is a record of the bore made just north of the town of 

 Greenup, by Messrs. Dtjnlap & Co., in 1S66, for oil :

1. Shale 51

The very hard rock No. 5 which was found here at the depth of 181 

 feet is probably the Quarry creek limestone. Another boring was sub- 

 sequently made by Mr. Talbot near his mill at the railroad depot, for 

 coal, and the following is his report, given from memory :

As this boring was made especially in search of coal, it is probable 

 that closer attention was given to the character of the beds passed 

 through than at the other, and the section reported corresponds much 

 better with the outcrops in Clark county. The hard rock, which I 

 presume represents the Quarry creek limestone, was found in the Talbot 

 boring at a depth of 140, while at the Dunlap well it was reported at 

 181 feet, although the latter well was commenced at a level at least ten 

 to fifteen feet below the former ; hence we may infer that the reported 

 depth of the boring was no more reliable than the character of the
