This is certainly the easiest and most simple method for the vineyardist; can be followed successfully with the majority of varieties, which have moderately soft wood, and even a part of the hard wood varieties will generally grow, if managed carefully.

MODE OF OPERATING.
There are several methods, which are followed with more or less success. I will first describe that which I have found most successful, namely, short cuttings, of two or three eyes each, which are made of any sound, well ripened wood, of last season's growth. Prune the vines in the fall or early winter, and make the cuttings as soon as convenient; for if the wood is not kept perfectly fresh and green, the cuttings will fail to grow. Now, cut up all the sound, well-ripened wood into lengths of from two to four eyes each, making them of a uniform length of say eight inches, and prepare them as shown in Figure 3.
These should be tied into convenient bundles, from 100 to 250 in each, taking care to even the lower ends, and then buried in the ground, making a hole somewhat deeper than the cuttings are long, into which the bundles are set on their lower ends, and soil thrown in between and over them. In spring, as soon as the ground is dry enough, the cutting-bed should be prepared. Choose for this a light, rich soil, which should be well pulverized, to the depth of at least a foot, and if not light enough, it should be made so by adding some leaf mould. Now draw a line along the whole length of the bed; then take a spade and put it down perpendicular along the line or nearly so, moving it a little backwards and forwards, so as to open the cut. Now take the cutting and press it down into the cut thus made, until the upper bud is even with the surface of the soil. The cuttings may be put close in the rows, say an inch apart, and the rows made two feet apart. Press the ground firmly down with your foot along the line of cuttings, so as to pack it closely around the cutting. After the bed is finished, mulch them with straw, or litter, spent tan or saw-dust, say about an inch thick, and if none of these can be had, leaves from the forest may be used for the purpose. This will serve to protect the young leaves from the sun, and will also keep an even moisture during the heat of summer, at the same time keeping the soil loose and porous. If weeds appear, they should be pulled up, and the cuttings, kept clean through the summer. They will generally make a firm, hardy growth of from one to four feet, have become used to all the hardships and changes of the weather; and as they have formed their roots just where they ought to be, about eight inches below the ground, will not suffer so much from transplanting, as either a single eye or a layer, whose roots have to be put much deeper in transplanting, than they were before, and thus, as it were, become acclimated to the lower regions. For these reasons, I think, that a good plant grown from a cutting is preferable to that propagated by any other method. In the Fall, the vines are carefully taken up, assorted and heeled in, in the same manner as described, with single eyes, and cut back to about three inches of their growth. They are then ready for transplanting into the vineyard.
IV.—BY LAYERING.
This is a very convenient method of increasing such varieties as will not grow readily from cuttings; and vines thus propagated will, if treated right, make very good plants. To layer a vine, shorten in its last season's growth to about one-half; then prepare the ground thoroughly, pulverizing it well; then, early in spring make a small furrow, about an inch deep, then bend the cane down and fasten it firmly in the bottom of the trench, by wooden hooks or pegs, made for the purpose. They may thus be left, until the young shoots have grown, say six inches; then fill up with finely pulverized soil or leaf-mould. The vines will thus strike root generally at every joint. The young shoots may be tied to small sticks, provided for the purpose, and when they have grown about a foot, their tips should be pinched off to make them grow more stocky. In the Fall they are taken up carefully, commencing to dig at the end furthest removed from the vine, and separate each plant between the joints, so that every shoot has a system of roots by itself. They are then either planted immediately, or heeled in as described before.
