The wires must be stretched taut on the posts, for which purpose any one of a half-dozen good wire stretchers may be purchased at hardware stores. Some growers loosen the wires after harvest to allow for the contraction in cold weather and others use some one of several devices to relieve the strain. Most growers, however, find it necessary to go over the vineyard each spring to drive down loosened posts and stretch sagging wires, and so take no precautions to release wires in the fall. All agree that the wires must be kept tight during the growing season to protect buds, foliage and fruit from being injured from whipping. _Tying._ The canes are tied to the trellis in early spring, and under most systems of pruning the growing shoots are tied in the summer. This work is done by cheap men, women, boys and girls. A great variety of material is used to make the tie, as raffia, wooltwine, willow, inner bark of the linden or basswood, green rye straw, corn husks, carpet-rags and wire. The same materials are not usually employed for both canes and shoots, since the canes are tied firmly to hold them steady and the work is done early before there is danger of breaking swelling buds, while the summer shoots are tied to hold for a shorter time and more loosely to permit growth in diameter. Tying usually follows accepted patterns in one region but varies greatly in different regions. There is a knack to be learned in the use of each one of the materials named, but with none is it difficult, and an ingenious person can easily contrive a tie of his own to suit fancy or conditions.

No other fruit is so completely transformed by the grower's art from its natural habit of growth. Happily, the grape endures cutting well, and the pruner may rest assured that he may work his will in pruning his vines, following to his heart's desire a favorite method with little fear of seriously injuring his vines. Because of its accommodation to the desires of man in the disposition of the vine, there are many methods of training the grape; there being in the commercial vineyards of eastern America a dozen or more. However, the differences and similarities are so marked that the several methods fall into a simple classification which makes conspicuous their chief features. Thus, all of the methods fall under two chief heads: (1) The disposition of shoots; (2) the disposition of canes. _The disposition of shoots._ Bearing shoots are disposed of in three ways in training grapes; shoots upright, shoots drooping, and shoots horizontal. The terms explain themselves, but the three methods need amplification since their adoption is not optional with growers but depends on several circumstances.
