Guide To Patapsco Valley Mill Sites Our Valley's Contribution To Maryland's Industrial Revolution

This study is part of a project for Patapsco Valley State Park. Is it a complete comprehensive study? Not by a long shot. It is the best collection of this type of information available at this time. It is a study built upon information based in it's bibliography. There is still much to do. When asked how much time it took? I say forever! It never ends! As soon as I finish a section new material seems to surface. I regularly get telephone calls asking, adding or correcting materials. If pursued I would say about eight hours of research per mile to cover both our 1993 and 2003 studies.Peirce, James Walter is the author of 'Guide To Patapsco Valley Mill Sites Our Valley's Contribution To Maryland's Industrial Revolution', published 2004 under ISBN 9781418452971 and ISBN 1418452971.
