I have only examined that part of Eastland County which lies north of theline of the Texas and Pacific Railway, and will not attempt a description ofany of its natural resources in the present Report except that of the coal inthe northern part of the county. The only place where any prospecting hasbeen done in this part of the county is near Cisco. The mines at Cisco are on seam No. 7. At one time and another therehas been considerable work done on this seam in the vicinity of Cisco. Theoutcrops are numerous. The seam is twenty inches thick, with a band ofslate above it, followed by a seam of coal four inches thick. The band ofslate is from four to ten inches thick between the coal seams. At anotherplace where I examined this seam there are nine inches of coal and twentyinches of bituminous shale. EASTLAND COUNTY. 545. 546 GEOLOGY OF NORTHWESTERN TEXAS. This shale will burn when put on the fire, but loses none of its bulk inburning, and is absolutely worthless as a fuel. There is no probability thatthis seam can be worked in this particular locality, owing to the thinness ofthe seam and the further fact that the stratum of bituminous shale will haveto be taken out of the mine, for it is so highly impregnated with sulphuretof iron that when the material is exposed to the atmosphere and it begins toslack, the sulphuric acid escaping will set the whole mass on fire. The seammay be thicker at some distant locality, but there is no hope that it will changefor the better anywhere near Cisco. Four miles from Cisco, to the north-west, on the line of the Houston and Texas Central Railway, this same seamof coal was found about the level of Sandy Creek. A good deal of work wasdone at this place sever
