50 GEOLOGICAL SURVEY OF ALABAMA. 
“Y” of the Blocton Mineral Railroad at the Tacoa depot 
and the Squire house on the main line. 
Commencing at said north “Y” and going southeast 
along the railroad, your first steps will be on the fine 
grained sandstone underlying the Whetrock seam ; you will 
next find the hard block sandstone thirty or forty feet 
underneath the Wadsworth ; this hard block sandstone is 
one of the most remarkable rocks for hardness in the whole 
of our coal measures; it is generally from two inches to six 
inches in thickness, breaks up into blocks of from two to 
seven or eight inches across, nearly square. This block 
sandstone has generally a very pale pea green, or very pale 
blue color. The first seam you pass over is the Whetrock 
seam, of about two feet in thickness, dipping to the south- 
east; all the measures along the South and North Railroad 
in this basin have a direction of dip to the southeast. 
Leaving the Whetrock, and passing over forty-seven feet of 
measures, mostly sandstones, you reach the outcrop of the 
Wadsworth seam. My oldest pits exposing these two 
seams, are only a few yards from the South and North 
Railroad at the point between the north “Y” and the main 
line. A few years ago the seams could be seen from the 
railroad, but the wash from the higher ground has covered 
them up. The following is a section of the Wadsworth 
seam taken at this point :
