66 GEOLOGICAL SURVEY OF ALABAMA. 
The Whetrock seam, or under-seam of the Wadsworth, is 
thin at this point. 
The following is a section of the Wadsworth and Whet- 
rock seams in the Cahabu basin, the Wadsworth being the 
upper, and separated from the Whetrock by forty feet of 
measures : 
| Wadsworth and Whetrock seams, at the Carr & Davis slope, in N. W. 14 
of N. W. 14 of section 9, township 20, 8., range 8, W.; direction of 
strike N., 15° E. from the true meridian, direction of dip S., 75° E., 
rate of dip 16°}.

Since the above section was made the South Birmingham 
Coal and Iron Company, who have bought the property as 
stated above, have driven the slope further down in the 
basin and I am informed they found the Wadsworth much 
thicker than three and a quarter feet, 
The Gould seam, I consider after examining it at different 
points, will average three feet in thickness in this basin; it 
is an easily mined coal and has a good roof; I have always 
found it in this basin a solid seam, without any serious 
layers of slate in it, though I have seen it in the Coosa field 
with a twelve inch layer of slate in the middle of it. The 
Gould seam in the Cahaba field bids fair to be worked ex- 
tensively in the future for the purpose of making a superior 
quality of coke.
