upright systems, as the High Renewal. At the 

 annual pruning only one cane is left. This com- 

 prises twelve or fifteen buds, and is tied up 

 diagonally across the trellis, the point or end of 

 the cane usually being bent downward somewhat, 

 in order to check the strong growth from the 

 uppermost parts. The shoots 

 hang from this cane, and 

 they may be pinched back 

 when they reach the ground. 

 In the meantime, a strong 

 shoot is taken out from the 

 opposite side of the head 

 which usually stands a foot 

 or less from the ground to 

 make the bearing wood of 

 the next year; and this new 

 cane will be tied in an op- 

 posite direction on the trellis 

 from the present bearing 

 cane, and the next renewal 

 shoot will be taken from 

 the other side of the hea'd, 

 or the side from which the 

 present bearing wood sprung; 

 so that the bearing top of 



the vine is alternated in either direction upon the 

 trellis. This system, and similar ones, allows of 

 laying down the vines easily in winter, and in- 

 sures excellent fruit because the amount of bear-
