The vine, however, does not unite with the same facility as the pear and apple, and, to ensure success, must be grafted under ground, which makes the operation a difficult and disagreeable one. It will therefore hardly become a general practice; but, for the purposes above named, is of sufficient importance, to make it desirable that every vineyardist should be able to perform it. I have generally had the best success in grafting here about the middle of March, in the following manner: Dig away the ground around the vine you wish to graft, until you come to a smooth place to insert your scion; then cut off the vine with a sharp knife, and insert one or two scions, as in common cleft-grafting, taking care to cut the wedge on the scion very thin, with shoulders on both sides, as shown in Figure 4, cutting your scion to two eyes, to better insure success. Great care must be taken to insert the scion properly, as the inner bark or liber of the vine is very thin, and the success of the operation depends upon a perfect junction of the stock and scion. If the vine is strong enough to hold the scion firmly, no further bandage is necessary; if not, it should be wound firmly and evenly with bass bark. Then press the soil firmly on the cut, and fill up the hole with well pulverized earth, to the top of the scion. Examine the stock from time to time, and remove all wild shoots and suckers, which it may throw up, as they will rob the graft of nourishment and enfeeble it. Others prefer to graft in May, when the leaves have expanded, and the most rapid flow of sap has ceased, keeping the scions in a cool place, to prevent the buds from starting. The operation is performed in precisely the same manner, and will be just as successful, I think, but the grafts that have been put in early, have the advantage of several weeks over the others, and the latter will seldom make as strong a growth, or ripen their wood as well as those put in early. Mr. A. S. FULLER performs the operation in the fall, preventing the graft from freezing by inverting a flower-pot over it, and then covering with straw or litter. He claims for this method--1st. That it can be performed at a time when the ground is more dry, and in better condition, and business not so pressing as in spring.--2d. That the scion and stock have more time to unite, and will form their junction completely during the winter, and will therefore start sooner, and make a more rapid growth than in spring. It certainly looks feasible enough, and is well worth trying, as, when the operation succeeds, it must evidently have advantages over any of the other modes.
