"Norton and I went to Sanford where we watched thousands of Chimney swifts enter a large chimney on the Sanford Mohair Mill . . . they flow in, in a steady stream from the Northeast." - a journal entry on this date in 1933 by Herbert M.W. Haven, of Portland. Haven, the founder of Haven's Candy Kitchen, was an amateur naturalist of statewide renown. (Source: Tales of a Homemade Naturalist: The Maine Diaries of Herbert M.W.
