330 GEOLOGY OF ILLINOIS. 



I examined, and no fossils were obtained here, this seam is only provisionally 

 referred to No. 2 of the general section. A similar seam is reported in section 

 17, township 12, range 6, at the foot of the bluff, along Indian creek. This 

 outcrop has not been worked to any extent. 



The general dip of the Coal Measure strata in this region appears to be to 

 the southeast, though not uniformly, but rather in undulations. 



Coal No. 6 first appears in Stark county near its northern line, in township 

 14, range 6/ Here it lies above the creek, and continues above it to the south- 

 ern line of section 16. From here it is not exposed for several miles down the 

 creek. At Medina, section 1, township 13, range 6, it lies considerably below 

 the bed of the river. About a mile west of here it is some ten or more feet 

 above Jack creek, a branch of Spoon river, and farther down this creek, and 

 near its mouth, the coal lies but little above its bed. Farther south, and a lit- 

 tle west, in the northern part of section 14, where it is again exposed, it lies 

 some ten or twelve feet above the river. The exposures, thus far, have all 

 been on the west bank. Half a mile south, and near the eastern line of the 

 section, the coal appears some distance up the bluff, not less than twenty or 

 twenty-five feet above the river. In the northwestern quarter of section 23, 

 it is again exposed along a little run, and but a few feet above its bed. South 

 of here, and near the eastern line of section 2(5, it crops out some twenty or 

 thirty feet above the river. On the level upland, and but a short distance 

 from the bluff, there are two shafts. The first one is about 50 feet deep, and the 

 other one, which is but a few hundred feet to the east, is about 3 Ofeet deeper, 

 both working this same coal. South of this, I did not learn of any exposure 

 for about five miles, when, in section 23, township 12, range 6, it again crops 

 out some six or eight feet above the bed of the river. The course of Spoon 

 river from here is to the southwest, and this coal seam does not, probably, 

 again appear near the river. A statement of the workings and outcrops of 

 coal No. 2, will be found in the report of Knox county. 



Economical Geology. 



Stone for building purposes. Stark county is not very abundantly supplied 

 with good material for these purposes. The supply is unevenly distributed, 

 some parts being destitute, while in others there is plenty. There are but few 

 valuable deposits of limestone in this county. In sections 21, 22, township 14, 

 range 7, the most extensive bed is exposed. It is from six to twelve feet 

 thick, and furnishes considerable building stone, but the layers are thin, sel- 

 dom exceeding four inches, and are very uneven. The stone is of a light drab 

 color, compact, even textured, moderately hard, and is uninjured by the weather. 

 The following section will show the position of this limestone to the underlying 

 coals :
