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 haye, 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. 3a, and the coal seam often found 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. J have nodoubt that it is theequivalent 
of the Patnam 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.
