Caption reads "Another View of No. 3 Mill Looking down the lumber conveyor from sorting table. The seven cabins house the electric motors that drive the conveyor. Each drives twenty nine rolss. Lumber moving at the rate of three and a half feet a second takes nearly five minutes to reach the sorting table."
The steam-powered No. 3 Mill was built in 1871 along the southern shore of the Ottawa river, east of the Madawaska. It burnt in 1875 and a new mill was built on the same site, opening for production in 1882. It was equipped with the newest machinery of the day, including a 190 foot "Iron Bullet Waste Burner." With the construction of Mills 3 and 4, output grew immensely and the McLachlin Bros. were producing 60,000,000 feet of lumber in a good year. A newspaper article from 1923 stated that there was a downturn in business and that only Mill 3 and 4 were in use for a few months per year. The mills ceased operation in 1929. It was demolished in 1937.
Photograph shows logging crewmen, pointer boat and barge bunkhouse. Among the crew is the foremen, tallyman, cook, cook's helper/camp maintenance and log drivers. In the background are the windmill and beehive burner of the McLachlin Bros. Mill No. 3. The initials 'SB', visible on some oars and the boat may stand for 'sorting boom'.
Caption reads "All the edgings, the slabs too small to be re-sawn, and the waste from the re-saw fall on a transfer and pass under the five slash-saws shown here. These saws, electronically driven, cut this material into four-foot lengths and deliver it to the main conveyor running full length of the lath mill."
