boviclcns, ScMzodus Alpinus, S. amplus, Macroclieilus inliabilis, Eupacliycrinus 

 tuber culatus, or a closely allied species, Zcacrinus mucrospinus, and several un- 

 determined species of Bryozoa. This group of fossils, if found in connection 

 with a coal, the position of which could not be determined from the associated 

 strata, would certainly be considered as strongly indicating an upper coal hori- 

 zon, and their occurrence here at the very base of the Coal Measures, shows 

 that many species at least, of the fauna of the carboniferous epoch, range 

 through the whole extent of the coal-bearing strata. 



We also found this seam well exposed in the cuts of tha C. B. & Q. railroad, 

 through the bluffs on the north side of Spoon river, below Lewiston. It is 

 divided here by a parting of shale, which leaves both divisions of the seam too 

 thin to be of any practical value for mining, as the average thickness of the 

 two divisions ranges from six to twelve inches only, and they are too widely 

 separated at this point to be mined together. In the vicinity of Bernadotte, a 

 good section of the lower coals may be seen in the bluffs of Spoon river, but 

 the horizon of No. 1 coal was only indicated by a bed of bituminous shale, four 

 feet in thickness. 



The following section was made near .Bernadotte : 



Clay shale with iron ore 5 to 6 



Sandstone and shale 15 " 20 



St. Louis limestone 6 



No. 1 coal is probably represented in the above section by the lower bed of 

 bituminous shale, and we find two additional seams of bituminous shale below 

 the upper coal in this section that are not found at Seaville. Nevertheless, 

 there can be no doubt of the equivalency of the strata at these localities, as at 

 both, the sandstane at the base of the section rests directly upon the St. Louis 

 limestone. 



In the vicinity of Avon, in the northwest corner of the county, a seam of 

 cannel coal occurs, occupying, apparently, about the same horizon as the lower 

 bed of bituminous shale in the foregoing section, though, from the imperfect
