24 GEOLOGICAL SURVEY OF ALABAMA. 



highly inclined coal seams, in and near the base of Straight 

 Mountain, and to assign them to their true position and re- 

 lation to the other seams. Examination of seams was made 

 and measurements taken in the Cowden Gap in section 28, in 

 the Waide Gap in section 27, and in the Cloivdus Gap in 

 section 13, all in T. 13 of R. 1 east. Also in the Allgood Gap 

 in S. 4, T. 12 of K 2 east, with the following results : The 

 outcrop of the Cowden Seam is in the S. E. of S. E. of S. 28, 

 515 feet southeast of the vertical rocks, average dip of strata 

 in this space 15 southeast, height of seam above the high- 

 est of the vertical rocks, at the southeast base of Straight 

 Mountain, 171 feet. y 



This seam varies in thickness from 3 feet 9 inches to 4 

 feet 6 inches. The coal is of low grade, impure, cokes im- 

 perfectly, gives a red ash. It shows here the following 



SECTION : 



Roof, yellowish-brown shale Seen 6 feet. 



COAL , 30 inches. 



Slate, dark, soft 4 inches. 



COAL 16 inches. 



Bed Rock, hard, gnarly, yellow-gray sandrock. 



No other outcrop of coal was found up the branch toward 

 the southeast from which the relation of this seam to those 

 above or below it could be inferred. 



About a mile southwest of the Cowden Gap opening, on 

 "Dry Branch," a seam of coal was exposed which was 

 classed as identical with the Cowden Seam, which showed 

 the following 



SECTION : 



Roof, slate 



COAL, slaty 30 inches. 



Shale, parting 7 inches. 



COAL 15 inches. 



Clay, dark 4 inches. 



Bed Rock, hard sandstone.
