Tt is not generallx known how it is that trees grow' knots. It, is to be mentioned in explanation that trees are formed of three parts—-the roots, the parent stem or trunk and the branches. When the trees are cut up into lumber the first of these parts is useless, and generally is left in the ground to he salvaged later for other purposes. The branches of the tree are also comparatively useless, but the trunk produces a number of valuable planks in proportion to its diameter. In spite of the fact that the branches have been lopped off. they leave their marks upon the parent stem in the shape of hard round or oval spots, which are called iC knots.” Each of these knots shows where the limb of the tree was growing, because the limb had its beginning in the heart of the trunk, drawing its sustenance directly from the central source of supply. The hardness of knots is, of course, due to the fact that more strength is required at the* base of the limb than farther out. Another illustration of the thoroughness of nature.
