YOUNG COUNTY. 501 



same sandstone was found in this at the top as was seen in the Russell shaft. 

 The coal, of which we took samples from a heap at the mouth of the mine, 

 presented the same general appearance as that of the coal from the other 

 openings in the vicinity. An analysis of the coal is given in another part of 

 this Report. 



Plate VII shows the various localities mentioned in the vicinity of Carbon- 

 dale. 



JONES MINE. 



About one-half mile southeast of Carbondale, on the J. C. Jones survey, is 

 the Jones mine. An opening has been made on the coal seam for more than 

 one hundred feet. The tunnel was partly filled with water from surface 

 drainage at the time of my visit so that I could not enter it. 



The top part of the coal is eighteen inches thick, then four inches of slate, 

 and then two feet of coal. The roof is a heavy bedded yellowish sandstone 

 with uneven structure. The coal is thicker here than at any place I have 

 seen in the vicinity, and it is the only place where the heavy-bedded sand- 

 stone lies directly upon the coal. From some cause the clay and shaly sand- 

 stone that is ordinarily above this coal seam and the massive sandstone have 

 been destroyed and the sandstone has formed upon the coal bed. 



This state of things continues for some distance, for on Huffstuttle Creek, 

 about two miles west of Carbondale, the coal outcrops again, and it is there 

 again overlaid by the massive sandstone. 



About one-half mile east of Carbondale and about the same distance north 

 of the Jones mine coal has been taken out of a shallow pit in the bed of a 

 branch. The pit was filled up at the time of my visit so that I could not see 

 the coal nor any of the surrounding strata, and can not therefore say whether 

 it is the same or a different seam from that at the Jones mine, but take it to 

 be the same. 



About two miles and a half south of Carbondale there is an outcrop of the 

 coal in a branch. The seam is divided by one foot of impure limestone. 

 The bottom part of the seam is twenty-two inches thick and the upper part 

 twelve inches thick. From some cause the parting in the seam, which at all 

 other places where I have seen it is slate, has here changed into an impure 

 limestone. Above the coal is a shaly sandstone and on top of that is a con- 

 glomerate. The same seam is seen just a small distance east of this place, 

 and there the parting between the beds is slate. About three feet of coal is 

 shown at the last place mentioned. About a mile northeastward from the 

 last mentioned place, on the eastern side of a hill, the coal outcrops below a 

 bed of limestone, very much the same as at the mouth of Whisky Creek on 

 the Brazos above Belknap. Between the bed of limestone and the coal seam 

 40— geol.
