Of pines, the white spruce is the most common here: the red and black spruce, the balsam of Gilead fir, and Banksian pine, also occur frequently.

The larch is found only in swampy spots, and is stunted and unhealthy.

The canoe birch attains a considerable size in this latitude, but from the great demand for its wood to make sledges, it has become rare.

The alder abounds on the margin of the little grassy lakes, so common in the neighbourhood.

A decoction of its inner bark is used as an emetic by the Indians, who also extract from it a yellow dye.
