I have not spoken of grafting the branch above ground. A few words on that will suffice. It may be as readily done as below ground, and with nearly the same prospect of success, but can scarcely be hoped to be enduring, unless a new vine is made of it by layering, so that the utility of the art will be diminished, except in particular cases.

If the grafting is done below ground, no cementing is needed, and the cleft or splice mode may be chosen, according to convenience. The fitting is always supposed to be well done, and the fine, permeable soil somewhat compactly replaced, and the shading by no means omitted. Some stocks in the open air will form no granulations, and no operator will succeed with them. If there is great natural dissimilarity in the texture of the wood, the union will be reluctant. Delaware will join with Clinton so that close observation is needed to discover the junction. In the propagating-house no fear is ever entertained as to the result; and it may be remarked, the scions that, are well grown in the propagating-house will grow when those which are produced in the open air will fail. The perfection of the wood secures the result in one case, and wan of it causes failure in the other. Imperfectly ripened wood from deficiency of climate, or numerous other causes, often defeats the operation. A frame and sash will, under good management, secure success in grafting the vine.

It must be remembered that the vine has a repugnance to a union with a foreigner even of the nearest affinity, and will make great efforts to do its "upper air work with its own apparatus, rejecting, if possible, that which is thrust upon it. The young shoots, which will generally start in profusion, must be watched and removed before they appear above ground, or at least at their first appear ance. If their leaves are suffered to expand, the action is fatally turned iron the graft.

For the amateur, an operation of skill and beauty, and, withal, to test hi dexterity and skill, may be performed in the summer - the last-of June or be ginning of July. A piece from a fine healthy cane of last season is taken, of which a shoot of short-iointed wood of the current year is growing, perhaps having made a length of eighteen inches. This shoot is cut back to one large leaf, which will have a well-developed bud at its base, and also a lateral, which must also be shortened to one leaf. The portion of old wood taken may ex tend from an inch and a quarter to an inch and a half above and below the current year's shoot. Half of the wood opposite the shoot is to be taken off by splitting in the middle. On the vine which is to receive this, have a cane of last season selected of equal size, and from which a piece carrying a shoot is to be removed to receive that already prepared. Accuracy of fitting, as well a rapidity of performance, is required to insure success. The piece must be firmly bound to its place by slips of bass. It must then be surrounded with moss, securely and neatly tied, which is to be kept moist for a few days, until union has taken place.

It must also be shaded by a surrounding of paper, see cured by tying above and below.

The cane is now to be cut off immediately above the first shoot above that on which the operation has been performed, and the shoot above shortened to two or three leaves. This shoot is to be entirely removed after the graft ha begun to grow strongly. The opposite dangers to be guarded against an first, attempting it too early, and before the new shoot has sufficiently advanced in the formation of wood and development of buds; for next season's buds are called upon to do the growing; second, to avoid dangers from immaturity of wood by lateness and consequent weakness at the end of the season. Buddin; may be performed successfully, so far as growing of the bud is concerned, but is an operation of no value except to the curious.

Grafting of the vine is much less extensively applicable with advantage that the grafting of trees, from other causes than those mentioned. The stock chosen are often unsuitable; if of the wild vine, for want of similarity of struc ture. One of fine texture, like the Delaware, will form a lasting and happy union with one that is coarse and dissimilar. One that has lost health and vigor will not have it restored by grafting, and one that has been badly planted will suffer from the defect much more decidedly than before; and in such cases, when the ground is already occupied by hungry roots, the remedy by layering, which is easily applicable when young stocks are used, is inadmissible because the first possessor will keep it filled with its own roots, despite their frequent removal. Grafting an old vine is, under the most favorable circum stances, but a temporary expedient, which will, after all, be not fully satisfactory; and the same care and skill, if expended upon a well-chosen new vine, will not only build up a new status which will be perpetual, but will yield by layers judiciously taken a remuneration for the past and revenue for the future.

Albeit, I do not advise the taking of layers from choice fruiting vines; in the first place, for a reason of my own, which I will not divulge; and in the second, because it will take proportionately from its productiveness, and much more than proportionately from its size and beauty, as well as from the quality of the fruit.

Just as I am about to conclude, the Horticulturist, with the communication from El Medico, comes before me with his long chapter of failures, in answer to which I am able to add very little. I have for many years been conversant with the "old German" vineyardist of whom he speaks, and have repeatedly witnessed his success and that of his Cincinnati neighbors in grafting. To have-the scions of well-ripened, but not gross wood, is a point indispensable to success which I have omitted to notice; and wood that has been well grown in a house is greatly to be preferred, as it is for all propagating purposes. I hope these hints will furnish El Medico with suggestions of all the important conditions of success, as well as dangers to be avoided.

[There, El Medico, you have the philosophy of grafting the grape. If you [ others master the principles upon which success depends, the application of the different modes of performing the operation becomes greatly simplified. Let us know how you like it, and whether you would like to have the modus operandi illustrated with cuts. We take it for granted that you, in this matter, represent a large class of our readers. You will also find something to your purpose in Mr. Adair's article. The Doctor, we are glad to see, has adopted our word " vineyardist." Though not in the dictionaries yet, it has the merit of being regular in its formation, and is concise and expressive. - Ed].
