The rows arenine feet apart, and the vines and posts twelvefeet apart in the row. Contiguous rows arebraced by a connecting-pole, as in Fig. trunk of the vine ends in a T-shaped this T-head, five canes are carried outfrom spurs.

Thechief advantage of this training is that it allowsof the growing of bush-frnits between the rows,as seen in Fig. 308.
