EDGAR, FORD AND CHAMPAIGN COUNTIES. 269 



was not strongly enough marked to decide their relations; but my impression 

 at the time was, that the limestone was the higher bed. I will not, however, 

 insist upon that interpretation of the facts, since it in no way affects my deter- 

 mination about the overlying beds, and Prof. E. T. Cox, who surveyed Clark 

 county, though confessing that he nowhere saw the direct connection of the two 

 sets of beds, is very strongly of the opinion that the sandstone is the higher. 



From the Koman Catholic church before mentioned, there is an almost con- 

 tinuous outcrop, down Brouillet's creek, as given in the section, until we meet 

 the first workable coal seam just below the State line. A similar section is ex- 

 posed upon Coal creek, two or three miles farther south, which joins Brouillet's 

 creek at the Indiana furnace. On both these streams, Nos. 13 and 18 furnish 

 large quantities of ironstone nodules of fine quality. 



No. 11 of the section, with its numerous pebbles of black, bituminous lime- 

 stone, furnishes a readily recognizable horizon, for some miles along the creek, 

 near and below Baldwinsville. 



No. 12, although quite variable in character within short distances, is no- 

 ticeable for containing the Caulcrpites marginatuSj which marks the same level 

 along the Salt Fork in Vermilion county. 



No. 14 contains a few fossils in good preservation, such as Spirifer lineatus, 

 S. planoconvexus, Spirifeiina Kentuckensis, Pleurotomaria sphserulata, P. Gray- 

 villensis, Productus longispinus, Cyathaxoniaprolffera, Astartella, etc. 



The coarsely concretionary structure of No. 19 allies it with corresponding 

 beds in Vermilion county, which there lie perhaps thirty feet higher than coal 

 No. 7. 



With the exception of the limestone No. 3 of the section, whose distribution 

 has already been spoken of, the small outcrops along the streams in the south- 

 ern part of the county are so disconnected, and of such common characters, 

 that it would be next to impossible to determine their exact equivalents in the 

 section. On Clear creek, in the northwest quarter of section 7, township 12, 

 range 11 west, a few feet of a soft, fine grained sandstone, somewhat ferrugin- 

 ous, has been quarried to a small extent, principally for grindstones. It is un- 

 derlaid by four or five feet of very dark drab clay shale. This may be the 

 equivalent of No. 12 of the section, but I am rather inclined to believe that No 

 7 has here taken the form of a sandstone. In either case, it is not impossible 

 that the report may he correct, that coal was struck at eighty feet, in a boring 

 made in this neighborhood some time since. The shales and irregular shaly 

 sandstones, which outcrop just at the railroad bridge over the main branch of 

 Sugar creek, evidently belong to Nos. 4 and 5 of the section. In going down 

 this creek, we find no beds of rock evidently in place, except about a mile north 

 of Elbridge, where two or three feet of soft, drab clay shale make their ap- 

 pearance at two or three points, but give no indication of their position in the
