The big dig

What do you think is buried in Harvard Yard - besides trust-fund receipts and tattered khakis? Tomorrow is Harvard Yard Summer Excavation Results Day for the Archaeology of Harvard Yard project, a course for student archeologists digging for 17th-century structures and artifacts. Prior excavations have unearthed 17th-century printing type from the nation’s first printing press. See what they found this time and bring questions for staff and students. Aug. 4 from 8:30 to 11:30 a.m. (rain date is Aug. 6). Free. Harvard Yard, Cambridge. 617-496-1027. www.peabody.harvard.edu
