PEUNIN-G GKAPE VINES. 147 



part of the shoot, which had now reached the top of 

 the house and had borne the croj) of grapes, were 

 cut clean out. The following was the appearance of 

 the same four vines, after they had been pruned in 

 the third winter, when they were in a state to pro- 

 duce their futl crop in the following season. (Fig. 30.) 



In the fourth summer a full crop was produced 

 both in the upper and lower half of the house ; the 

 longer shoot d bore its bunches on the upper half of 

 its length, and it was not suffered to extend itself by 

 a leading shoot ; the shorter shoot c bore its bunches 

 on its whole length, and extended itself by a leading 

 shoot to the top of the house ; the sput e was suffered 

 to become a shoot, extending a few joints beyond half 

 the length of the rafter, and from the bottom of the 

 old wood a weaker shoot, as before, was trained, to 

 become the foundation of the lower shoot of the 

 next season. In the pruning season, d, which had 

 become the longest branch in the previous winter, 

 was entirely cut away from the bottom ; the shorter 

 branch c, which had now become the longest, was 

 stripped of its spurs on its lower half of the old wood, 

 and its upper half was left for bearing ; the" extended 

 spur E, became the lower bearing branch, and the 

 weak shoot f (Fig. 31.) at the bottom, was reduced to 

 a spur, to furnish the lower wood for the next year.
