In search of a 19th-century outhouse in Dorchester

The Boston Preservation Alliance posts an interview with city archaeologist Joe Bagley. He brings us up to date on the archaeological digs in the front yard of Old City Hall (site of an even older home for Boston Latin School) - they've found the remains of a building, but which one? - and alerts us that his next major project will be at at the Epiphany School in Dorchester, looking for an outhouse that would have been in use when the site was home of the Industrial School for Girls in the mid-19th century.
