Plants are also propagated by layers. To do this, take a shoot which comes up near the root, bend it down so as to bring several eyes under the soil, leaving the top above-ground. If the shoot be cut half through, in a slanting direction, at one of these eyes, before burying it, the result is more certain. Roses, honeysuckles, and many other shrubs are readily propagated thus. They will generally take root by being simply buried; but cutting them as here directed is the best method. Layers are more certain than cuttings. _Budding and Grafting_, for all woody plants, are favorite methods of propagation. In all such plants, there is an outer and inner bark, the latter containing the sap vessels, in which the nourishment of the tree ascends. The success of grafting or inoculating consists in so placing the bud or graft that the sap vessels of the inner bark shall exactly join those of the plant into which they are grafted; so that the sap may pass from one into the other. The following are directions for _budding_, which may be performed at any time from July to September: [Illustration: Fig. 64] Select a smooth place on the stock into which you are to insert the bud. Make a horizontal cut across the rind through to the firm wood; and from the middle of this, make a slit downward perpendicularly, an inch or more long, through to the wood. Raise the bark of the stock on each side of the perpendicular cut, for the admission of the bud, as is shown in the annexed engraving, (Fig. 64.) Then take a shoot of this year's growth, and slice from it a bud, taking an inch below and an inch above it, and some portion of the wood under it. Then, carefully slip off the woody part under the bud. Examine whether the eye or germ of the bud be perfect. If a little hole appear in that part, the bud has lost its root, and another must be selected. Insert the bud, so that _a_, of the bud, shall pass to a, of the stock; then _b_, of the bud, must be cut off, to match the cut b, in the stock, and fitted exactly to it, as it is this alone which insures success. Bind the parts with fresh bass or woolen yarn, beginning a little below the bottom, of the perpendicular slit, and winding it closely around every part, except just over the eye of the bud, until you arrive above the horizontal cut. Do not bind it too tightly, but just sufficient to exclude air, sun, and wet. This is to be removed after the bud is firmly fixed, and begins to grow. Seed-fruit can be budded into any other seed-fruit, and stone-fruit into any other stone-fruit; but stone and seed-fruits can not be thus mingled. Rose-bushes can have a variety of kinds budded into the same stock. Hardy roots are the best stocks. The branch above the bud must be cut off the next March or April after the bud is put in. Apples and pears are more easily propagated by ingrafting than by budding.
