“Think about it,” said Browne on Saturday at an orientation session for the dig, held at the Wright Building. “The meetinghouse was everything.”

A town’s meetinghouse served as the house of worship, courthouse and town hall, Browne said.

Chartier told the large crowd gathered at the Wright Building that they would be looking for the town’s second meetinghouse, built in 1707. The first meetinghouse was where the cemetery is now. The third meetinghouse was constructed on Tremont Street.

Some initial ground penetrating radar scanning has been done on the site, Browne said. This is often a first step in an archeological dig and can show where the foundation of the building is. The cost of the radar was offset by the First Parish Church.

“The radar has already indicated some interesting things about the site,” he said. “Once that information comes in, we’ll know where to dig.”

Chartier is excited about the possibilities.

“This site has the potential to cover the entire period of New England history,” he said. “We don’t know what’s out there.”

The dig will take place from Oct. 6-18, and volunteers will work in three hours shifts. People will be assigned different jobs including diggers, note-takers, photographers, washers and cataloguers. The site will be arranged in a grid, and volunteers will dig test pits along the grid. Then the pits will be carefully  excavated.

“Archeological site are such a limited resource,” Chartier said. “We want to do it right and for the right reasons.”

Chartier told the interested volunteers they may not be finding entire artifacts –– perhaps just a piece of a pot, a few nails, the lead from a window, etc. However, he said a careful process and a trained eye will be able to spot these fragments.

“When you’re actually out digging, you’ll be able to see these things jump out at you, the stains and so forth,” Chartier said. “When you dig, if you see any kind of funny shaped rock, call us over.”

Even these little pieces can provide the team clues. For example, Chartier said the lead used to hold in diamond-shaped pieces of glass in old windows often has a date stamped on it, or the name of the manufacturer.

“That gives you a real absolute date to work from,” he said.

Although there is no concrete proof the second meetinghouse was situated on the Chestnut Street lot, Chartier said he was excited to get digging.

“There’s a high likelihood something was going on here,” he said.
