Historian Renny Stackpole will discuss the antebellum period of shipbuilding and the impact of the Civil War on this industry at the Thomaston Historical Society, Thursday, June 13, at 7 p.m.

The presentation is part of the Georges River Land Trust’s 2013 Walks and Talks series exploring the environment and history of the St. George River.

Stackpole, a resident of Thomaston, former director of the Penobscot Marine Museum and trustee of the General Henry Knox Museum, will focus on letters of the Gilchrist family of Thomaston, a major source for information on the topic.

Thomaston was a major shipbuilding center, and the talk will appropriately be held at the Historical Society, 80 Knox St., adjacent to the current Lyman-Morse boatyard and the last original building of Montpelier, General Knox’s mansion, which has been recreated further north in Thomaston.

Shipbuilding was and continues to be a significant industry in the area, and the mission of the land trust includes conserving the traditional heritage of the Georges River watershed region.

The land trust's annual Walks and Talks include hikes on the Georges Highland Path, paddles on the St. George River, the Garden Tour and lectures on flora, fauna and environment. The next event is a paddle and lunch on the middle St. George on Saturday, June 22, beginning at 10 a.m.
