146 GEOLOGY OF OHIO. 
It will be noticed that in this section a bed of limestone occurs near 
the surface, and that the lower part of the boring was in a thick bed of 
- sandstone. This sandstone is the massive stratum which overlies the 
Briar Hill coal, sometimes coming down to it, and sometimes even cut- 
ting it out completely, but more generally resting upon a bed of shale of 
variable thickness. The place of Coal No. 1 is plainly below the bottom 
of this hole. 
Since my first visit to Edinburgh, Mr. Chapman has continued his ex- 
plorations, and others have been carried on by Mr. D. W. Goss, but, so 
far, 1 believe, without very satisfactory results. The many borings made 
show great irregularity in the deposition of the strata here, and it is evi- 
dent that this has been a region through which rapid currents of water 
have swept, which have cut away the coal seams, and deposited sands and 
clays in a very unequal way. This will be evident upon an examination 
of the records of some of the drillings. A well bored one mile north-east 
of the Center gave—

It is evident that this boring has gone far into the Waverly, and it 
reveals the fact that the Conglomerate is here absent. This is somewhat 
surprising, as in the valley of the Mahoning, only a few miles distant, it 
is fully one hundred feet in thickness.
