the supply of fuel, as at various points along the lake shore, ete. The 
principal points, nevertheless, of the iron industry of the State will be 
within the limit of the coal area, or closely connected to it by railroad 
communication. While the districts and chief centers of the manufac- 
ture will be spoken of more fully at another place, brief mention may 
be made here of those towns which stand foremost in the iron industry 
of the State. First—Cleveland, on the shore of Lake Erie, is the great 
seaport or distributing place of the ores of Lake Superior, Canada, etc., 
for Northern Ohio and Western Pennsylvania, as well as being the 
commercial center for the iron manufacture-of Northern Ohio. It also 
possesses itself large iron works, which are destined to be multiplied 
greatly, and make the Cleveland district of Ohio a great manufacturing 
center, a rival to its namesake, the celebrated Cleveland district of 
England, besides being the principal source for supplying the markets 
accessible by the chain of the great lakes. Second—Closely connected 
by railroad and every interest, Youngstown, in Mahoning county, is 
the chief town and manufacturing center of the celebrated region of the 
Mahoning Valley, and for real enterprise and quantity of product this 
region leads the manufacture in the State. Third—Steubenville, on 
the Ohio river, is the seat of an important iron industry, which is more 
closely connected in conditions of manufacture and interests with Pitts- 
burgh than with Cleveland. Fourth—The Ohio towns, Martin’s 
Ferry, Bridgeport and Bellaire, opposite to Wheeling. These towns and 
Wheeling, though now occupying a minor position in the iron manu- 
facture on the Ohio river, by the unusual facilities which they have for 
water and railroad communication, and the enormous supplies of fuel 
in the great coal seam, which is everywhere visible in the vicinity, 
must soon occupy a pre-eminent one in this manufacture in the 
valley of the Ohio. Fifth—Ironton, in the extreme southern part of 
the State, on the Ohio, in Lawrence county, is now the center of the 
celebrated Hanging Rock region, and an important point of manufac- 
ture. The circumstances of the supply of ores and fuels, transpurta- 
tion, etc., more fully alluded to when describing the region, offer such 
conditions that we may anticipate for it progress-and high position 
among the manufacturing towns of the State. Beside these chief points 
mentioned, there are others whose importance is not so great, as Lee- 
tonia, in Columbiana county, Massillon or the Tuscarawas Valley, Zanes- 
ville, Jackson, Columbus, and the Hocking Valley. On the lake shore,
