C. IRON POINT ORE. 
Five analyses of the ore from this valuable seam are given below. 
Most of the samples come from beyond the field considered in the present 
report, but the horizon is well marked in the Hanging Rock District. 
_ The analyses are not equally complete. 
1. Fannie Furnace, Shawnee—oné hundred and five to one hundred and twenty feet 
above Coal No. VI, calcined ore. | 
2. Gould and Moore’s lands, Carbon Hill—Ward township, Hocking county, one hun- 
dred and thirty feet above Coal No. VI. From weathered outerop of seam. . 
3. Moxahala Furnace, Whitlock Bank.

C. PIG IRONS. 
The results of four analyses of the iron made by Star Furnace, Jackson 
county, will be found below. This furnace uses native ores solely and Jack- 
son Shaft coal for fuel. There is no other furnace district of the State 
in which all the materials that go into the stack are deriyed from the 
immediate neighborhood. Some use Lake Superior or Missouri ores, 
and some use Connellsville coke in connection with the native supply, 
but no,foreign materials are here employed.
