The article (below) published in the Rutland Herald Oct. 28, 1931 was reprinted Feb. 22, 1994. It discusses area blockhouses, including Capt. Thomas Sawyer's blockhouse in North Clarendon Village, and events from the 1770's.
The photo above is of the 1750 blockhouse at Ft. Edwards in Nova Scotia. We do not know what area blockhouses looked like, but the blockhouse shown may be representative. A photo of a similar design can be seen in the Fort Hill entry in the Places collection.
