basal eye) in order to provide wood for the fol- 

 lowing year. At the pruning following the one 

 represented in the cut, the fruiting part of the 

 arms- will be removed at M, and a new fruiting 

 spur or cane made of the cane which comes from 

 the eye on the wood spurs w. The basal bud on 

 w will in all probability have produced a cane 

 which can be cut back to one eye to furnish a 

 new wood -spur. If this is not the case it shows 

 that too much wood was left the first year, and 

 therefore no fruit -cane should be left on this 

 arm, but only a single spur of two or three eyes. 

 This will be a return to short pruning, and must 

 be resorted to whenever the small size of the 

 canes or the failure to produce replac- 

 ing wood near the head of the vine 

 shows that the vigor is diminishing. If, 

 on the contrary, the arm shows an abun- 

 dance of vigorous canes, proving that 

 the vine has not overborne, a fruit -cane 

 may be left from one of the shoots 

 coming from the lower buds of the 

 fruit -cane c, and a new wood -spur of

the canes, from the wood-spur of the previous 



year (w) . In this case, the removal of 



the arm at k is deferred one year, and the extra 



vigor of the vine is made use of to produce an 



extra crop.
