Dark blemishes in the lumber as a result of branches growing from the tree trunk

These are hard cross-grained disfigurements in timber which are formed where shoots on trees are developed into branches. The resin ducts in the timber run parallel to the growth and resin in the knots flow to the surface of the timber. The exposed surface of the knot must be sealed before paint is applied.
