By Layers.—Layering consists in preparing the branch of aplant while still attached to the parent, bending it sothat the partOf>erated on is brought under ground, and then fixing it there bymeans of a forked peg. Some plants root so freely that they needonly pegging down; but in most cases the arrest of the returning sapto form a callus, and ultimately young roots, must be brought aboutartificially, either by twisting the branch, by sphtting it, by girding. Fig. 15.—Propagation by Layers—<j, tonguing; b, ringing. it closely with wire, by taking off a ring of bark, or by tonguing the leaves are cut off the portion which has to be broughtunder ground, and a tongue or slit is then cut from below upwardsclose beyond a joint, of such length that, when the cut part of thelayer is pegged an inch or two (or in larger woody subjects 3 or 4 in.)below the surface, the elevation of the point of the shoot to an uprightposition may open the incision, and thus set it free, so that it may be surrounded by earth to induce it to form roots. The wholebranch, except a few buds at the extremity, is covered with best seasons for these operations are early spring and mid-summer, that is, before the sap begins to flow, and after the firstflush of growth has passed off. One whole summer, sometimes two,must elapse before the layers will b
