CLAY COUNTY. 95 



of fossiliferous limestone which probably belongs above the coal. 



Three-quarters of a mile south of Maysville is a sandstone quarry 

 owned by Hugh Miller. The rock is of a yellowish gray color, and the 

 exposure from seven to eight feet thick. The so-called "salt pond" is on 

 the south half of sec. 4, T. 3, R. S, and is a bog surrounded by high 

 ground. Sticks may be thrust into it through the spongy mass to the 

 depth of ten or fifteen feet, and cattle, and formerly wild animals also, 

 resorted here for water. 



At Moore's quarry, on sec. 14, T. 4, R. 6, there is a fine grained buff 

 sandstone that was used in the foundation, and also for caps and sills 

 for the Masonic Hall building in Louisville. There are three layers of 

 the rock exposed from 8 to 10 inches thick, over laid by two feet of siliei- 

 ous shale. 



At J. Elkiks' place, on sec. 36, T. 5, R. 5, the following section was 

 found:

LimestoDe in the bed of the creek ? 



Down the creek the limestone is two feet thick, the upper part full of 

 encrinite stems and Fmulina cylindrica. The limestone is quite compact 

 and will take a good polish. Still lower down on the creek there is a 

 thin coal below the limestone. This limestone is again seen on Lime- 

 stone creek, on sec. 34, T. G, R. 4? near the. north line of the county." 



The limestone above mentioned is undoubtedly the same as that 

 found over the coal at Lamkius' mine near Louisville, and on Dismal 

 creek east of Larkiusburg, and a limestone very similar in appearance 

 is found on Muddy creek near the north-east corner of the county, 

 where it is quarried both for lime and for building stone. 



E co no mica I Geology, 



Coal. — The only coal seam in the county that promises to be of any 

 value for mining operations is that at Mr. Lamkin's place northwest of 

 Louisville, and this is so unevenly developed that there are probably 

 but few localities in the county where it will prove to be of any prac- 

 tical value. At some points it affords from 18 to 20 inches of good 

 coal and possibly may thicken at some localities to a little more than 

 that, while at others it thins out to a few inches or is wanting altogether, 

 and its place is only indicated by a thin streak of bituminous shale. 

 Where well developed it affords a very good quality of coal, and may 

 be worked to advantage in a limited way to supply the local demand. 

 I believe it to be the same as the Nelson coal found in the south-west 

 corner of Effingham county, which is JSTo. 16 of the general section and 

 the highest workable coal in the State.
