Ice used to be a commodity here in Wolfeboro. Back in 1956 the E.V. Moody company delivered 1,600 tons of it to local residents during the summer ( Source 1 ). The ice was harvested out of Goodwin's Basin, now Fernald's Basin, which is part of Lake Wentworth, packed in sawdust and stored in a building off Center street (source 2). My grandfather worked for the company just after World War II. There is also a granite bench with plaque donated by the Moody's near the harvesting location on the Bridge Falls Path. The company shut down in 1964.
Another service the company performed, prior to the invention of bubblers in 1960, was to break up accumulating ice around piers and docks along Winnipesaukee and surrounding lakes.
