540 GEOLOGY OF NORTHWESTERN TEXAS. 



On the south side of Hubbard's Creek, about one mile from the Berry 

 Meadows mine, there is another outcrop of the same seam of coal. 



SLOAN SHAFT. 



One mile north of the Jake Wizeart mine, on the north side of the hill 

 fronting on the Clear Fork of the Brazos River, an opening has been made 

 on the coal seam that shows the seam to be about the same as at the other 

 places mentioned in the vicinity. 



On the north side of the Clear Fork of the Brazos, and about one and a half 

 miles north of Crystal Falls, is the Wasson mine. The coal outcrops in the 

 head of the hollow, and is about at the same level as the Sloan mine. There 

 is over this seam the same shaly limestone as seen at the outcrops and shafts 

 on the south side of the river, and it is evidently the same seam. A tunnel 

 has been driven into the hill at this place directly north one hundred feet, 

 following the coal. The coal at this place is thirty-six inches thick, with 

 the same seam of shale as seen at the other places. Here it is six inches thick. 

 The bottom layer of coal is twenty inches thick and the upper layer sixteen 

 inches thick. 



ALBERT SIDNEY JOHNSTON MINE. 



About six miles west of the town of Crystal Falls, on the Albert Sidney 

 Johnston survey, the coal seam is in the bed of the Clear Fork of the Brazos 

 and is always covered with water. 



It was at this place that the United States soldiers when stationed at Fort 

 Griffin used to get their coal. They would wade into the river and with 

 levers prize up the blocks of coal and float them to the shore and load them 

 on their wagons. This is the same seam (No. 7) as was seen at Crystal Falls, 

 A few years ago Charles A. Ashburner, of the Pennsylvania Survey, visited 

 this place, and his report of the locality put the bed of coal at this place forty- 

 five feet below the seam at Crystal Falls; but this could not be for the reason 

 that the strata dip to the northwest, and this locality being west of Crystal 

 Falls it would necessarily be at a lower height than at Crystal Falls. I ran 

 in a line of levels between the two places and traced the outcrop from hill to 

 hill as well, and know that it is the same seam. 



The seam could not be examined with any degree of satisfaction at this 

 place, as it was at least two feet under water. Its thickness has been re- 

 ported as at least four feet, but I do not consider the report as any way re- 

 liable. The seam will have to be worked at this place on the west or north 

 side of the river. There is, however, a high hill on the east side that will 

 furnish very good cover, but the probabilities are that the covering is poor in 

 the valley on the east side of the river in the Johnson Bend.
