In 1874, the Ontario-Quebec boundary was surveyed and the land above Lake Temiskaming, including the northern townships, was mapped by Dr. Robert Bell and his assistant Arthur Barlow in 1887.
In 1899, Barlow wrote a report on the geology and natural resources of the area, which suggested that the rich belt of clay that lay north of the big lake was ideal for agricultural settlement.
They were followed by settlers from Renfrew and the Southern Counties of Leeds, Cumberland, Frontenac and Lennox & Addington, many of whom where descendants of United Empire Loyalists United Empire Loyalist Paddle wheel boats operated by Oliver Latour in the early 1880s, from the most southern tip of Lake Temiskaming, at Mattawa traveling as far north as 'Uncle Tom's Town' on the Blanche River delivering settlers, livestock and supplies.
