Constructed in 1867, Mill No. 2 was the second mill built by Daniel McLachlin on the Madawaska river at the bridge. Called "The Little Mill", it was smaller in size and output than Mill No.1, beside it. After the much larger Mills No. 3 and 4 were built along the shore of Chats Lake in the 1870s and 80s, Mills no. 1 and 2 slowly ceased production. All of the mills ceased operation in 1929 due to a decline in business over the 1920s. However, Mill No.2 operated again to saw logs for shipment to the J.R. Booth Company from 1936 to 1938. Its stone foundations were demolished in 1972 when Ontario Hydro constructed the weir.
