Two lumber mills began operating on the island in the early 1880s. In 1912, the Stone Lumber Company at Marksville had added 13 km of railroad with a locomotive to reach dense woodlots up the mountain and deliver timber to the mill. For a time both the train and mill were operated around the clock. By the end of the 1910s, the mill had produced and shipped two and a half million board feet of maple and pine lumber around the world. The rail line operated for almost 25 years until mill ceased operation in the depression of the 1930s and the tracks were dismantled.
