454 GEOLOGY OF OHIO. 
Sharon, Middlesex, etc., where conditions precisely similar to those of 
the Mahoning Valley in Ohio, are the basis of an ae of almost 
equal importance. 
2. The Tuscarawas region, at present represented by but two fur- 
naces in blast. } 
3. The River region, or region of Steubenville and environs of 
Wheeling, where the fuel used is coke, and the ores Lake Superior and 
Missouri. In this division are included the various establishments at 
Leetonia, Columbiana county, Irondale, Steubenville, Mingo, Martin’s 
Ferry and Bellaire. But as a slight exception to the generalization of 
the materials of this region, at Leetonia there is used some little native 
ore and no Missouri ore, and a certain proportion of raw coal in addi- 
tion to the coke. 
4, Central Ohio or Hocking Valley region, where the fuel is raw 
coal from the Hocking Valley, with some admixture of coke and the 
ores of Lake Superior and Missouri with about one-half native coal 
measure ores. 
5. The Hanging Rock region of Southern Ohio. ‘The ores are the 
celebrated hydrated and carbonated ores of the Coal Measures, and the 
fuel charcoal, coke and raw coal. This region comprises some forty- 
two furnaces in blast, and some in course of erection, in the counties of 
Vinton, Jackson, Gallia, Scioto and Lawrence. At Jackson, Ironton, 
ete., the use of raw coal has been successful for several years past, and 
at Ironton quite a considerable quantity of Missouri ore is now im- 
ported. 
6. In thesixth region we may include the isolated points of manu- 
facture in the northwestern part of the State, where the Lake Superior 
ores are smelted with charcoal, as at Antwerp and Cecil, Paulding 
county. ‘This region is now of little importance, as possibly before this 
appears in print, these charcoal furnaces will all be abandoned, but it 
may confidently be expected that there will rise in their stead, at 
various points on the Lake Shore, where railroad communication is 
direct with the coal fields, other establishments using the Lake Superior 
ores, and raw coal or coke from the rich deposits of the eastern part of 
the State. ‘Thus at Toledo, Sandusky, Elyria, or Black River, etc., 
the railroads to the coal fields and the excellent harbors present most 
excellent facilities for important industries. These same remarks apply 
with equal force to the future prospects of such towns as Painesville, Ash-
