178 CULTURE OF THE GRAPE. 



training is also a great help. There is, therefore, no 

 practical difficulty in obtaining good eyes within a rea- 

 sonable distance from the base by the single, short-spur 

 system. But, should the spur increase in the course of a 

 few years, a new shoot from one of the dormant eyes at 

 the base of the spur may be trained up for one season. 

 The old spur may then be cut away, and the wound cov- 

 ered with shellac dissolved in alcohol to a creamy thick- 

 ness ; and the young shoot will then form a new spur as 

 good as the first. Upon old canes, it will be well to 

 renew one or two spurs on each vine each year, rather 

 than do the whole work of renewal upon a vine in 

 a single year.
