There is very little need of saving much of the old 244 GRAPES wood except to form a trunk and enough of the last years growthto furnish the buds necessary for the main shoots of the nextseason (Fig. 170). An examination of the accompanying figureswill give a clear idea of the great amount of wood that can be cutaway each year. For example, if five or six buds are left to form asmany more shoots, there will be as much new wood as the rootsystem can support and bear a crop of fruit. The effect of not pruning the vines each year is to so graduallydivide the strength of the plant that the new growth in any one partis very limited and the possibility of fruit is thereby reduce
