UConn Professor Robert Thorson will be at the library to speak about the history of New England stone walls, with an emphasis on eastern Massachusetts. Thorson will describe the historic and technological stages that led to the phenomenon now considered to be the signature landform of rural New England. The talk will be followed by a question and answer period and general discussion. Copies of his three books will be available for purchase, signing and inscribing. This program is part of our Lifelong Learning Series and co-sponsored by the Wayland Historical Society.
