Usage [3]  A light brown dye is obtained from the bark; The bark is a source of tannins; The bark can be used as a cork substitute; The bark contains pitch, it burns with a lot of heat and almost no smoke, so it is prized as a fuel; The small roots have been used to make baskets; The plant has insecticidal properties; A resin is obtained from the trunk, similar to Abies balsamea; The resin can also be used as a caulking material on boats; A fast growing and fairly wind-resistant tree, it is often used in shelterbelt plantings; Wood - heavy, strong, fine grained, durable, though it can be of variable quality. It dries quickly, does not warp and is easily worked, it is used for heavy construction, telegraph poles, furniture etc; It is also used as a good quality fuel;
