Excerpt from The Pennsylvania Magazine of History and Biography, Vol. 28 Rolling Mill at Manchester, in Allegheny County, to make iron rails. Connected with this mill were two coke furnaces, built in 1863. The company operated the works until Sep tember, 186 7, when they were leased by Springer Harbaugh. On January 1, 1870, Harbaugh, Mathias Owens took pos session as owners, and on August 1, 1874, they failed, when the manufacture of rails was abandoned. The works them selves have long been abandoned A few other iron-rail mills in Western Pennsylvania, including those which were equipped for the manufacture only of mine rails and other light rails, need not be mentioned. Of these mills those which made rails of heavy sections never at any time pro duced any considerable tonnage. It is a noteworthy fact that Allegheny County, with all its enterprise in the manufacture of iron and steel, did not begin to make rails of heavy sec tions until the Superior Rolling Mill was built in 1865. Iron rails are not now made in Western Pennsylvania, except occasionally a very few tons of light rails for lum ber and mine roads.
