62 GEOLOGICAL SURVEY OF ALABAMA. 



This seam has also been cut by James Smith on the hills 

 or river bluff, northeast of the Locust Fork, but the pros- 

 pect was not so good as on the southwest side of the river. 

 Probably the seam becomes thinner northeast of the river. 

 The hill or high ridge which contains this seam does not 

 extend far in that direction. One mile northeast of the 

 river it becomes broken up into knobs, and these soon be- 

 come less and less prominent, until they sink into an undu- 

 lating plateau, which does not contain any of the coal seams 

 of the quartzitic group. 



The downward flexure of the coal measures, in this basin, 

 has its greatest depression at, or near, the Locust Fork of 

 the Warrior, in a southeast and northwest direction; and 

 northeast of the river the measures are gradually elevated 

 till they attain their normal level. The lower coal seams of 

 this group must necessarily come to the surface within one 

 or two miles northeast of the river. The measures here 

 contain much less rock and hard strata than exists south- 

 west of the river, and are more abraded. The outcroppings 

 of the seams have not been discovered ; there are no rocky 

 ledges to designate their positions, and it is very probable 

 that they very materially thin out towards the northeastern 

 end. 



Number 26 of the General Section is a seam that as yet 

 has received no distinctive name, and about which but little 

 is known.' 



It lies immediate between the Upper Bairn, Carnes Seam 

 No. 25, and the Bynum Seam No. 27 of the General Section. 



Some prospector first cut this seam in a pit on the north 

 side of the long high ridge which holds the quartzitic group 

 of coal seams, in the S. E. of N. E. of S. 18, T. 12, E. 3 E. 

 Its position is about 40 feet above the Upper Bairn, Carnes 

 seam, and probably about the same distance below the Bt/- 

 num Seam. The pit was not cut far enough into the hill to 

 reach or expose any cap rock, or probably to show the full 

 thickness of the seam. 



The roof was shale. The seam had increased from 8
