Meekins Library, 2 Williams Street, Williamsburg, Mass.
Artifacts pulled from the Mill River after the 1874 Flood inspired ten third graders in Nicole Derby’s classroom at Anne T. Dunphy School to learn about local history.  Their research and the artwork and writing they created helped them to further understand the  Mill River’s history, and its connection to the production of silk thread, brass faucets, buttons, and more.  Enjoy an exhibit of their artwork and writing at the Meekins Library during the month of May.
