the lower part being mostly slaty sandstone, laminated 
sandstone, and yellow sandstone, the upper part being 4 
very massive grey or white sandstone which, in other parts 
of the field, becomes a conglomerate. You then arrive at 
the Buck seam, which at this point is four feet in thickness, 
of which the following is a section from actual tests in this 
basin:

The outcrop of the Buck seam can be seen in the little 
knoll or point between the south “Y” of the Helena and 
Blocton Branch of the Birmingham Mineral Railroad and 
main line near the wooden bridge. The Buck seam is a 
lower bench of the Mammoth seam, and the same as the 
seam they are now mining in the No. 1, No. 2, and No. 8 
slopes at the DeBardeleben Coal and Iron Company’s mines 
at Henryellen. Itis also the same as the Clark seam in 
the Lolley and Dailey Creek basins. The seam has been 
worked to a limited extent by the Hureka Company, by 
means of a tunnel from one of the gangways of their Black- 
shale slope. The Blackshale slope was south of the South 
and North Railroad, and in the irregular part of this 
basin. (a). 
Continuing southeast along the South and North Rail- 
road, and passing over thirty-five feet of laminated sand- 
stone, you arrive at three streaks of coal, (thin seams of a 
few inches each,) these thin layers of coal follow the meas- 
(a) I must here state that those conducting and superintending the 
Eureka Company’s work, sank this slope contrary to the advice of the 
writer, and after their attention was called to the irregularity of that 
part of the basin.
