THE BLOTINT MOUNTAIN COAL FIELD. 49 



readily located by the exposed fossils. It was hence called 

 the Guidt.' .s"/m, because it was a well known landmark, and 

 aided in assigning other seams to their proper horizons. 

 This seam is lost sight of in the divide between the two 

 main basins of this field, but makes its appearance again in 

 the Locust Fork basin. A good deal of coal has been taken 

 from it in sections 19 and 20 of T. 12, Kange 3 E. The coal 

 is equally as good as in the Blackburn River basin, and a 

 little thicker 12 to 14 inches thick. The overlying fossil- 

 filled shale is replaced by about the same thickness of fossil- 

 filled dark //.sx'/, slate. This is the only seam that is known 

 to carry this kind of slate. It mines up in large square 

 blocks, like roofing slate, and splits smoothly one way. 

 Wherever split there is at least one beautiful impression of 

 a fern leaf, or frond, on one or both sides of the slate. 



This seam was also seen on the bottom lands of Dry Creek 

 in S. 19, T. 11, of R. 4 E. about three miles east of Walnut 

 Grove. Slate fissile, and full of fossilleaf-impressions. 

 This coal seam was stripped and raised from the bed by 

 /n//-/v// HinjiH-x, occasionally, for many years. It is not 

 worked now, but is widely known as the Hoym-* !*<!. This 

 seam was only seen at these two places in the Locust Fork 

 U-isin. The position of the Haynes bed is close to the ele- 

 vated southeastern margin of Bristow's Cove the continu- 

 ation and representative of Straight Mountain with the 

 trend of the seam closing in toward that uplift. 



This condition is due to the fact that above, or northeast 

 of, the Locust Fork of the Warrior River, the trend of the 

 Cove is t-fiftt of northeast, and that in the course of about 

 twelve miles, this eastward trend has cut into the Blount 

 Mountain Coal Field about one and a half miles. Hence all 

 of the coal seams near its northwestern side are cut by the 

 edge of the cove at an acute angle, and end or terminate in 

 that uplift, which makes the southeastern rim of the cove. 

 Hence this seam cannot be found any farther toward the 

 1 northeast. This opening was made on its southeastern out- 

 crop, and at or near its most northeastern extension.
