WABASH AND EDWAEDS COUNTIES. 55 



In the bed of the river at low water there is an outcrop of micaceous 

 sandstone No. 2, of the first boring, which contains iron nodules, some 

 of which inclose fossil ferns, and one was found containing Leaia trica- 

 rinata. In the bed of the river, a little further down, an impure argil- 

 laceous limestone has been found below the river level. 



At Hanging-rock bluff, about three miles north-east of Mt. Carmel, 

 there is an outcrop of massive sandstone similar to that at the town, 

 which projects into the bed of the river at low-water, and rises above it 

 to the hight of 30 to 35 feet. Three quarters of a mile nearly west of 

 Hanging-rock, at Mr. Eeel's place, there is an exposure of the beds 

 above the sandstone showing the following section: 



Ft. In. 



Soft brown shales 4 to 6 



Bituminous shale 1 to 3 



Dark, hard bituminous limestone 3 



Coal— So. 10? 1 6 



Clay shale 1 to 2 



ilassire sandstone 30 to 35 



The limestone here is a steel-gray, passing into black, and weathering 

 to an olive-brown, and filled with crushed shells of small size, among 

 which Rkynchonella Osagensis seemed to be most conspicuous. It is 

 possible that the sandstone at Hanging-rock belongs below that at Mt. 

 Carmel, as the beds seemed to rise to the northward, so far as we could 

 find the rocks exposed, and this sandstone may be the bed No. 4 in the 

 boring made at the river bank. This seems the more probable from 

 the fact that no trace of the limestone or coal has been found above 

 the Mt. Carmel sandstone, where it should appear if these sandstones 

 are identical. Furthermore the outcrop at Hanging-rock is about a 

 mile to the eastward of the Mt. Carmel bluff, and the general western 

 dip of the strata would naturally bring up the lower beds in this direc- 

 tion. Furthermore the rock seemed harder and appeared to be less 

 affected by atmospheric influences at the former locality than at Mount 

 Carmel. If the sandstone is the same at these localities, the limestone 

 and coal at Keel's place must be a mere local deposit; but I believe 

 this limestone to be identical with that at Eochester mills in the river 

 bank, which represents the horizon of No. 10 coal. On Coffee creek 

 there is a good exposure of the beds overlaying this limestone, and the 

 following section, commencing in the bed of the river at low-water mark, 

 and extending up the creek for about a mile, shows the general charac- 

 ter and relative position of the rocks in this vicinity : 



Ft. In. 



No. 1. Coal, hard and splinty— No. 13 ? 3 



No. 2. Space unexposed ? 



No. 3. Brown shale 4 to 6 



No. 4. Shaly impure limestone 1 to 2 



No. 5. Clay shale li to 2 



No. 6. Blackshale 6 



No. 7. Coal— No. 12 4
