Join SVT, OAR, and the Maynard Historical Society on Thursday March 25, 7:00pm at Wolbach Farm for a talk about the History of the Ice Trade on the Assabet River. For much of the 19th century Boston was the hub of the ice export business, shipping ice as far as India. Thoreau writes in Walden of 100 men descending on Walden Pond the winter of 1846-47. Led by David Mark of Maynard, this talk will give you an in-depth history of the ice trade and ice houses on the Assabet River.
