This jack ladder was used to raise logs from Lake Nipissing to cars on the Nosbonsing and Nipissing Railway - the engine of one train can be seen on the left. The lift was powered by a waterwheel in the Wasi Falls, just beyond this image, connected to the lift by a rope. The image is looking to the south, with Nipissing on the right. The line ran 5.5 miles east to Lake Nosbonsing where the logs were dropped into the lake and then floated down the Mattawa River to JR. Booth's lumber mill in Ottawa.
