each of which will produce from one to three bunches of 

 blossoms. As soon as these can be distinguished the cane 

 should be pinched off to the last large cluster and one 

 leaf; thus there will be, when set, one large cluster of 

 fruit and one or more large leaves, besides the leaves of 

 the main canes. During the summer, as soon as a new 

 leaf has been formed beyond the last bunch, the end of 

 the cane is pinched off 

 and at the end of the 

 season we will have short 

 spurs upon which are 

 large bunches of grapes. 

 In pruning the laterals 

 after fruiting, cut back 

 so as to reduce the 

 length of the spur for 

 the next year's cane as 

 much as possible. Fig- 

 ure 113 shows how much 

 the s|)ur would be elon- 

 gated if the cut were 

 made at the large bud, 

 h, and how much shorter 

 it would be if the cut 

 were to be made as 

 sho\\Ti at a. 



Each succeeding sea- 

 son the work is a repeti- 

 tion of that of the third year until the permanent vine 

 reaches the ridge of the house. Each succeeding year, 

 however, will be likely to be met with some new- difficulty, 

 the result of climatic or other changes, insect pests or 

 fungous diseases, which must be met and overcome. If 

 a vine becomes weak or seriously injured by cold the 

 root often may be in a healthy condition, and the top 

 may be renewed by starting a new cane from the ground.
