This is a mis- taken view, as the scions and buds only perpetuate such char- acteristics- as they in- herit from the parent tree. "Wood of the previous season is preferable for grafting and should be taken only from the very best and most carefully selected parent trees. CLEFT GRAFTING. In its modifications grafting has been longer employed than bud- ding. It is performed during the late winter months just as the buds begin to swell, or very early in the growing period. At that time the upward flow of sap is most rapid and the union will be accomplished most quickly. Scions for any kind of grafting should be selected from the growth of the last season. Terminal twigs were formerly used almost exclusively and are still pre- ferred by some propagators. But, as the bud at the end of the branch rarel}^ produces a strong shoot, ordinarih^ drying up and fall- ing off instead, terminal twigs are no longer used to a large extent. A well-filed fine-tooth saw, a sharp graft- ing knife, a specially devised grafting tool (fig. 7), a short-handled wooden mallet (fig. 8), a quantity of raflia and grafting wax or gi'afting cloth, and a number of scions con- stitute the necessary equipment for grafting. In performing the operation of cleft grafting, the trunk or limb of the tree to be grafted (technically known as the stock) should be cut squarely across with the saw; the knife edge of the grafting tool should then be placed across the stock, either over the center or t
