ANNULAR OR RING BUDDING. This method is one of the simplest and safest to use on the walnut, and especially adapted to young trees of two or three years old, and to smooth limbs of large trees. In this method a ring is cut right around the stock, about an inch long. Then a ring of about the same size is taken from the scion, containing a bud, which is slipped into the corresponding space in the stock, and then bound tightly with soft cotton twine or cloth, covering it up to ex- clude the air. The operation should be per- formed when the trees are in full growth, during July, August, or September, and left to lie dor- mant through the winter, to be started in the Fig. 4- pared. A.

The walnut, as a rule, cannot be grafted successfully by the ordinary meth- ods practiced on fruit trees. The reason is that the scions contain but little wood, the pith in them being much greater than in scions of other trees; and when the scion is prepared (wedge-shaped) very little wood is left in it, and the bark is so thin that, when inserted, it cannot unite with the stock, not being held tlrmly in position. Terminal shoots, however, have a thicker bark and more wood, and are most successful in grafting. Side-grafting is accomplished with success, but can only be performed in the spring, when the sap in the stock begins to rise ; this is necessary, as the scion must be inserted when the bark peels, in the same manner as a bud. The walnut does not put forth until quite late in spring, and to secure good, firm wood it becomes necessary to gather the scions before the trees start; and that they may be kept dormant, a
