VERMILION COUNTY. 259 



Two analyses of coals from this seani, given in the aforesaid report, arc as 

 follows : 



Specific gravity 1.811 and 1.3127 



Moisture 9. " 6.4 



Volatile gases 34.5 " 39.17 



Carbon in coke 50. " 48.93 



Carbon in coal 58.8 " 53. 



Ash, (white) 6.5 " 5.5 



This seam has also been opened along Trosper branch, on J. Ogden's land? 

 in the northeast quarter of section 22, township 18 north, range 11 west, 

 about three miles northeast of Georgetown. At the time of my visit, the 

 openings had caved in, so as to prevent examination; and I was informed (hat 

 the coal here contained too much pyrite to be valuable. 



The only other coal openings in the county are the small stripping;* of the 

 thin seams Nos. 5 and 11 of the county section, which I have numbered pro- 

 visionally as coals No. 10? and No. 11 ?, and whose character and distribution 

 have been sufficiently described in the general description of the section. Small 

 quantities of coal of very fair quality can be obtained here for local use ; but 

 the seams are not thick enough to make them of any economical importance. 



Coal No. 8 (probably corresponding to No. 7 of the Illinois valley section 

 see 111. Rep., Vol. iii., p. 5,) does not appear at its proper level, in the section 

 of the rocks of this county, viz: under the limestone, No. 21 of the section. 

 Its only appearance in all this region is at the Horse Shoe bend of the Little 

 Vermilion, in the west half of section 20, township 17 north, range 10 west, 

 about a mile east of the State line, where it comes in suddenly, with a thick- 

 ness of from three to four feet, and a reported roof of black slaty shale. It 

 does not continue to the southward, and there is no reason to expect that it 

 will be found sufficiently developed to furnish any considerable amount of coal 

 within the limits of Vermilion county, though small patches may be found in 

 the regio.i ju.st west of the Horse Shoe. 



Through the region between the Big and Little Vermilions, no coal scams 

 have been developed; but there is every reason for believing that both "No. 

 7" and "No. 6" are in place under all the western portion of this area, except 

 on the slopes toward and near the Little Vermilion, where " No. 7 " can only 

 be looked for high in the bluffs. 



Where the State line crosses the Big Vermilion, the " Eugene" or " Hang- 

 ing Rock" seam, No. 4G of the county section, is probably about fifty feet be- 

 low the water-level, and, judging from the general dip of the rocks, should 

 come to the surface, in going north, before we reach the railroad at " Illiana," 

 or State Line station. In this region, however, the surface is unbroken, and 

 no wells or borings have exposed the rock, the Alluvium and Drift being appa- 

 rently rather deep. The "Hanging Rock " seam, however, even if found here,
