46 GEOLOGICAL SURVEY OF ALABAMA. 
19, range 2 west, the rate of dip was 25°; in the northwest 
quarter of the northwest quarter of section 36, township 19, 
range 2 west, on the J. S. Jones’ land, the direction of dip 
is northwest, and the rate of dip 80°. This steep dip is 
evidently caused by the great upthrow of the boundary 
fault that is in close proximity at this point. The most 
level point of this basin is that occupied by the synclinal 
and anticlinal in the north portion of the basin. The Acton 
basin is eight and a half miles in length by nearly five 
miles in average width, and contains an area of forty-two 
square miles. The amount of good workable coal in it, in 
seams of two feet thickness and upwards, and less than 
three thousand six hundred feet in depth, is from careful 
computation 143,000,000 tons net, making no allowance for 
waste in mining, loss in pillars, etc.; but this represents the 
gross amount.of coal in the ground.
