Where a vine has failed to grow the first season, replant with extra strong vines, as they will find it difficult to catch up with the others; or the vacancy can be filled up the next season, by a layer from a neighboring vine, made in the following manner: Dig a trench from the vine to the empty place, about eight to ten inches deep, and bend into it one of the canes of the vine, left to grow unchecked for that purpose, and pruned to the proper length. Let the end of it come out to the surface of the ground with one or two eyes above it, at the place where the vine is to be, and fill up with good, well pulverized earth. It will strike roots at almost every joint, and grow rapidly, but, as it takes a good deal of nourishment from the parent vine, that must be pruned much shorter the first year. When the layer has become well established, it is cut from the parent vine; generally the second season. Pruning is best done in the fall, but it can be done on mild days all through the winter months, even as late as the middle of March. Fall-pruning will prevent all flow of sap, and the cuttings are also better if made in the fall, and buried in the ground during winter. All the sound, well-ripened wood of last season's growth may be made into cuttings, which may be either planted, as directed in a former chapter, or sold; and are an accession to the product of the vineyard not to be despised, for they will generally defray all expenses of cultivation. TRAINING THE VINES ON ARBORS AND WALLS. This is altogether different from the treatment in vineyards; the first has for its object to grow the most perfect fruit, and to bring the vine, with all its parts, within the easy reach and control of the operator; in the latter, our object is to cover a large space with foliage, for ornament and shade, fruit being but a secondary consideration. However, if the vine is treated judiciously, it will also produce a large quantity of fruit, although not of as good quality as in the vineyard. [Illustration: FIG. 14. FIG. 15.]
