WILLIAMSON COUNTY. 115 



associated with shale and thin bedded sandstone. This is above the 

 section seen at the mill. The following is the section here : 



Ft. 



IMn bedded sandstone 8 to 10 



Sandy shale 1 4 to 6 



Coal No. 6 1 



Sandy shales to the water level 12 to 15 



Davidson's mine, one mile and a quarter south of Crab Orchard, 

 belongs to a still higher level, and the coal is there five and a half feet 

 in thickness overlaid by bituminous shale and a dark bluish gray impure 

 limestone. A little to the eastward of the coal mine the overlaying 

 sandstone is well exposed in the bed and banks of a shallow ravine, 

 showing a thickness of twenty to twenty-five feet. This sandstone 

 stands exposure well, and when found in beds of sufficient thickness 

 for heavy work furnishes a durable building stone. About three quar- 

 ters of a mile east of Davidson's mine the thin coal that outcrops at 

 Sarahsville was found in the bed of a small branch, and apparently 

 from forty to fifty feet below Davidson's coal. A section of the beds 

 seen here show the following order of succession : 



Ft. 



Brown and buff sandy shale and sandstone 20 to 25 



Dark ash-gray limestone 2 to 3 



Bituminous shale 1 to 3 



Coal Xo. 7 (Davidson's) 5 to G 



Fire-clay 2 



Unexposed 30 to 40 



Brown and buff sandy shale 10 



Coal Xo. 6 lto 11 



Bine sandy shale, exposed _. 1 



On Mr. Weley's land, two miles and a half southwest of Marion, a 

 thin coal has been found on Crab Orchard creek, which is probably 

 identical with the thin seam in the foregoing section. 



At Mr. Motsingee's mine, one mile and a half west of Crab Orchard 

 village, the coal is about five feet thick with a roof of bituminous clay 

 shale. The coal is of fair quality, tolerably free from pyrite, and the 

 upper eighteen inches is a good smith's coal. About a hundred yards 

 to the south of the coal opening the hard, dark, ash-gray limestone 

 usually found above No. 7 coal has been quarried and burned for limr, 

 though but poorly adapted to that purpose. The coal here and at 

 Davidson's is mined by tunneling into the hill side on the outcrop of 

 the seam. 



On Mr. Feank Ensmingee's place, one mile east of Crab Orchard, 

 the following beds overlaying coal No. 7 were seen : 



Ft. 



Hard sandstone in thin beda - 8 



Bine sandy shale 4 to C 



Brown shale and sandstone 10 to 12 



Blue shale « to 10 



CiDnainon-colored limestone - 1 



Bituminous shale A to 1 



Coal, said to be six inches thiftk A
