the very base of the other. The weak bud 



gives only a shoot ; but the next year it is cut 



to a strong bud and the 

 neighboring spur is cut 

 to a weak one. 



The vine in Fig. 329 

 has spurs in pairs. The 

 one on the left has 

 already been cut six 

 times. The pruning of 

 this vine is explained 

 in Fig. 330. The former 

 prunings are marked by 

 the letters. A more de- 

 tailed view of an old 

 spur is given in Fig. 

 331. 



It is generally best to 

 prune the vines as soon 

 as the fruit is off, there- 

 by allowing the vines 

 to be protected during 



the winter, and destroying the lodging places of 



insects and fungi.
