Pittsburgh is like Birmingham in England….Setting aside the streets, the shops, the houses, wagons, factories, public buildings, and population, perhaps it may be. It certainly has a great quantity of smoke hanging about it, and is famous for its ironworks.
Dickens visited Pittsburgh on the Pennsylvania Canal in 1842…. Apparently he wasn’t impressed.
