. 1. Block ore 6-8 



2. Blue shale 6-8 



3. Limestone, fossiliferous 8 



4. Thin coal. 



At Henry Hazelton's, a little higher up Monday Creek, the ore, seen 

 in the bed of the creek, which was believed to be the equivalent of the 

 block ore last mentioned, was found by Professor Irving, in 1869, to be 

 one hundred and fifty feet below the great seam. There is flint under 

 the ore, and a thin coal under the flint. At McCuneville, on Monday 

 Creek, still higher up the stream, there is a blue fossiliferous limestone 

 reported by Mr. McCune to be one hundred and fifty feet below the Great 

 or Nelsonville seam of coal. Thirty feet above this blue limestone is a 

 seam of coal from two to three feet thick. We have, I think, in a hori- 

 zon about one hundred and fifty feet below the Great, or Nelsonville seam, 

 the representative (if such exists in this region) of the Zoar limestone 

 of Tuscarawas county, which is said to overlie Coal No. 3. About forty 

 feet higher is the place of Coal No. 3a, with generally a limestone or 

 fossiliferous shale over it; while approximately midway between the two 

 coals mentioned is another thin seam also with a fossiliferous limestone 

 overlying it. The place of the Putnam Hill limestone is approximately 

 forty feet above Coal No. 3o, and the coal seam often fouad under it is 

 the seam No. 4. This makes the usual interval between Coals No. 3 and 

 No. 4, about eighty feet. This I have found to be the case in extended 

 examinations made in several counties in the First District, where these 

 numbers were first applied. Over each of these seams I have commonly 

 found a limestone, and quite often a limestone over No. 3a, which is 

 generally about half-way between the others. The Putnam Hill lime- 

 stone, the place of which is about eighty feet below the Nelsonville 

 seam, is not often seen in the Monday Creek region. On the hill back 

 of the Bessie Furnace, west of New Straitsville, there is a fossiliferous 

 limestone one foot in thickness, which is seventy-three feet below the 

 Nelsonville or Great seam of coal. I have no doubt that it is the equivalent 

 of the Putnam Hill limestone. The horizon of the Baird ore — here im- 

 bedded in fire-clay— is thirty-four feet higher. 



In the report for 1869, and more particularly in the map, the lime- 

 stones were confused, and in some cases the limestone over Coal No. 3a 

 mistaken for the Putnam Hill, and perhaps in one or two cases a still 

 lower limestone was called the Putnam Hill stone. So far as the errors 

 applied to the more eastern part of the region covered by that report, they 

 were corrected in the report on Muskingum county, in Vol. I, of the Final 

 Reports.
