The disturbed measures next to the northwest edge of the 
Blocton basin have a varying rate of dip of from six degrees 
to sixty degrees. The main part of the basin is nearly flat, 
the rate of dip varying from one degree up to fifteen de- 
grees. The synclinal of this basin is wide and flat, and ex- 
tends from the northeast end to the southwest end. 
Around the Cahaba Coal Mining Company’s mines the 
syuclinal becomes divided by an anticlinal that shows itself 
between No. 1 and No. 2 mines, into two synclinals, extend- 
ing for several miles in both directions. These synclinals 
are wide and almost flat, and embrace a large territory of 
nearly level measures. The inclination or fall of the syn- 
clinal line, of this basin, is from the northeast end to the 
southwest end. The base of the Millstone Grit, measured 
from a given datum line, has a lower altitude at the south 
end of both the Cahaba and Warrior Coal Fields, and a 
higher altitude at the north end of both Coal Fields than at 
any other point; consequently the large Montevallo Con- 
glomerate, the cap rock of our Alabama Coal Measures, is 
visible at the surface at the south end of both coal fields, 
which can be seen at the shoals in the Warrior River be- 
tween Tuscaloosa and Northport, and in the Montevallo
