The ore contains an undesirable per centage of silica, but in other re- 

 spects is of fair quality. When the mine is driven under the hills the 

 ore will become a blue carbonate, but probably much oxydized ore may 

 be obtained by stripping along the outcrop. Here, as at the Akron 

 Furnace, the ore, limestone, and coal are all in the same hill and can be 

 put into a furnace at very small cost. 



On Meeker Run, below Nelsonville, the Bessemer ore, one foot eleven 

 inches thick, is reported on the land of J. L. Gill, Esq. It is seventy-six 

 feet above the Nelsonville coal. It is eleven feet seven inches below the 

 Bayley's Run coal, here about ninety feet above the great seam. About 

 twelve feet below the Bessemer ore is the limestone, two feet ten inches 

 thick. On this limestone is a deposit of ore reported to be a foot thick. 

 I have no analyses of any of the ores on this estate, except that furnished 

 by Prof. T. S. Hunt, of the ore below the Nelsonville seam of coal, which 

 has already been given. 



I have little doubt that the Bessemer ore will be found extensively 

 in the hills west of the Hocking River, in the vicinity of Nelsonville. 

 I think I have seen traces of it on Floodwood, and it is reported at Salina, 

 and as far north as Lick Run. In the hills between the Hocking River 

 and Monday Creek it is often seen. W. B. Brooks,, Esq., reports its 

 existence, in fine thickness, on his coal lands in Section 19, Ward 

 township, Hocking county. It is said to be nodular above and in a solid 

 layer belovr. This ore is about eighty-five feet above the Nelsonville 

 seam of coal and eighteen to twenty feet above the limestone. The 

 Bayley's Run coal, three feet thick, is found a little above the Bessemer 

 ore. At an elevation of one hundred and fourteen feet above the Nelson- 

 ville coal is another reported deposit of ore, and still another one hun- 

 dred and s.iventy-six feet above the same coal. It has already been 

 stated that the Baird ore is found below the coal on the Brooks land.
