"Whip-grafting or tongue-grafting is the most usual mode of performing the operation. The stock is headed off by an oblique transverse cut as shown at a, a slice is then pared off the side as at b, and on the face of this a tongue or notch is made, the cut being in a downward direction; the scion c is pared off in a similar way by a single clean sharp cut, and this is notched or tongued in the opposite direction as the figure indicates, the two are then fitted together as shown at d, so that the inner bark of each may come in contact at least on one side, and then tied round with damp soft bast as at c; next some grafting clay is taken on the forefinger and pushed down on each side so as to fill out the space between the top of the stock and the graft, and a portion is also rubbed over the ligatures on the side where the graft is placed." &mdash; Encyclopedia Britannica, 1893
