GRAPES. 



its first training, and formed with two principals on each 

 side, making four principals to each vine. If, however, 

 the vines should consist of the larger-fruited class, such 

 as Muscat of Alexandria, Black Hamburgh, or Syrian, 

 &c., one principal on the rafter and one on each side 

 will be much better than more. It may likewise be 

 necessary to extend this system still further, where the 

 house is large, and has a great length of rafter, which 

 may be done by forming a second series one half the way 

 up the rafter : by this means a cop will be obtained 

 under the upper as well as the lower part of the roof. 



There are some who adopt a spur system in the ma- 

 nagement of their vines, and who obtain very good 

 grapes ; but in this case a provision must be made for 

 a supply of bearing wood, when the limbs producing 

 these spurs are exhausted, and require to be renewed. 



Vines against the open wall. 



In the management of Vines against the common 

 wall, where it is intended to be wholly occupied for 

 grapes, I should recommend a somewhat similar method 

 of pruning and training to be adopted as that under 

 glass ; with this difference, that instead of cutting 

 down alternately for two shoots, one only will be 

 required. 



The vines should be planted at six feet apart, and 

 supposing the young plant to have one good and vigour- 

 ous shoot, it must be cut down to three or four eyes. 

 As soon as the young shoots are long enough to nail to 

 the wall, two of the best must be selected, and trained 

 horizontally within nine inches of the ground : when 

 each shoot has extended two feet and a half from the 

 stem, it must be trained in a perpendicular direction for 

 two or three feet according to its strength, when it must
