 and small, it is customary to remove them by pulling 

 them off, rather than by cutting them off. In well-pruned 

 vineyards the cost of stripping ought npt to exceed $1 

 an acre. 



Early autumn freezing is one of the most damaging of 

 all forms of frost-injury, because the plant has no time in 

 which to recuperate, and a hard winter may add to the 

 destruction. Fortunately, such freezes before the foliage 

 falls are very infrequent. Probably little can be done 

 except to await the condition as it 

 presents itself in very early spring. 



It is not often that special treat- 

 ment needs to be given to plants 

 injured by late frosts; but the re- 

 moval of the killed 

 parts, or sometimes 

 even a further head- 

 ing-back, is the 

 rational procedure. 

 This should be sup-

 tillage and other 

 care.
