One of the special books in the Bullis Collection is titled: An Essay on Bridge Building: containing analyses and comparisons of the principal plans in use: with investigations as to the best plans and proportions, and the relative merits of wood and iron for bridges, by Squire Whipple (Utica, NY: H. H. Curtis, 1847).
A visitor to the Bullis Room this last week stopped by to look at this book again. The book and its author are of interest to many local people because the Aldrich Change Bridge, which was rescued from abandonment and re-erected in Macedon and Palmyra's Aqueduct Park during 2003 and 2004, was originally built in 1858 from a design by Squire Whipple.
We're not sure how this book came to be a part of the Bullis Collection, but it is invaluable as a source of bridge building techniques. If you haven't visited Aqueduct Park recently and looked at the Aldrich Change Bridge, we encourage you to do so this summer. Thanks to Squire Whipple's knowledge and a group of local volunteer bridge enthusiasts, it's there for us to appreciate and enjoy.
