These sections suffice +0 show the great want of uniformity in the ma- 

 terial directly above the lower coal; the last section, with five feet of 

 Conglomerate wedged between a three-foot coal above and a five-foot coal 

 below, does not indicate a proper Sub-conglomerate coal, or a coal below 

 the true horizon of the Conglomerate. It marks a local subdivision during 

 the deposition of Coal No. 1, after which, the debris of a Conglomerate 

 ridge bordering the marsh, was carried down on to the coal and re-ce- 

 mented into rock. Similar local deposits of Conglomerate debris are 

 found in the ropf of Coal No 1, in Trumbull county. This fact, men- 

 tioned in my report on that county in Vol. I, has been quoted by Prof. 

 Lesley, of the Pennsylvania Survey (report of progress, 1875), as evi- 

 dence that our Coal No. 1 is Sub-conglomerate, and he suggests that the 

 bed of sandstone found above this coal is a combination of the Conglom- 

 erate. While it is true, in Ohio, that Coal No. 1 is often, topographically, 

 below the Conglomerate, is bordered by Conglomerate and Waverly 

 rocks, which rise in hills of considerable height along the margin of the 

 old coal swamps, the debris of which is sometimes found in the roof of 

 the coal, it is quite certain that nowhere in the northern or north-west- 

 ern part of our coal-field is this coal geologically below the Conglomerate. 

 It is also certain that the great bulk of this rock is found outside of the 

 productive coal territory. The most of the ravines which penetrate far 

 into the Coal Measures and expose the rocks below the lowest coal, show 

 that this Conglomerate is very thin or wholly wanting. It would be of 

 incalculable benefit to the northern part of the State if this coal could 

 be found under the broad expanse of Conglomerate which covers the 

 most of Geauga and Medina counties and the northern parts of Summit 

 and Portage, but its base is exposed in too many places (where it is
