NEW YORK, Aug. 2 (UPI) -- A Hofstra University archaeological team says it will need at least two more summers to prove that the Lloyd Harbor estate in New York once housed slaves.
The team has so far unearthed around 1,000 artifacts dating back to the 1800's and will finish out their first summer of digging next week, New York Newsday reported Thursday.
The U-shaped foundations, postholes and artifacts that they have found have also helped them prove their theory that the structure once housed slaves.
Team leader Chris Matthews said they will need at least two more summers digging to fully document whether or not slaves lived at the estate.
"I don't think we'll have any trouble making a case for it," said Matthews, an associate professor of anthropology. "I think we've found enough to say that this was occupied in the 18th century, and there's no evidence at this point that anyone else was living on this property that would've occupied this house other than the laborers."
