On the northern line of the county, in Prairie township, this coal 
constitutes the “limestone” seam, mined by Joseph Redett. (See 
Figs. III and XI). The limestone roof is 5 feet thick; the coal is 3 to 4 
feet thick, averaging 39 inches; the clay floor is 5 feet thick. The 
arrangement of benches and partings is similar to thatat J. Amsbaugh’s 
(Fig. X). The middle bench carries a good deal of sulphur and is 
troubled with soot veins from 0 to 2 inches thick. The upper bench 
is cleaner, and is used as a smith’s and steam coal at Fredericksburg. 
In Richland township this coal was opened by Wm. White, but it 
proved to be of poor quality.

This coal was formerly mined and shipped by rail at Fredericks- 
burg, near the north line of Prairie township. 
It is the “sandstone vein” of Wayne Hill (Fig. IID), and was 
33 to 44 feet thick over a limited area, which is mined out. Around 
the margin, 32 inches of good coal remain, lying in one bench, and now 
mined on Joseph Redett’s farm. The coal isa cementing, purple ash 
coal, contains much sulphur, and is apt to attach to grate bars. This is 
the only place known where it is worth mining. On Rev. Mr.
