This depicts logging operations on the upper reaches of the Maine Rivers. Trees were dragged over the snow to banks of the stream, and shot down in the spring on ‘swollen waters’ to such cities as Bangor, where two hundred sawmills cut logs into boards and planks before being sent to ports, most often along the East Coast, but also around the world. Ox were much stronger than horses, and used more regularly early on before teams of horses became more common.
