154 CULTURE OF THE GRAPE. 



HIGH TRELLISES. 



The same rule will apply to all high trellises. When 

 the number of cordons, or fruiting-arms, exceeds two, it 

 is generally best to adopt the double-arm plan, as is rep- 

 resented in fig. 24, p. 125. When vines are trained on 

 the sides of buildings, instead of supporting them with 

 leather loops nailed to the building, as is frequently done, 

 it is far better for the building and for the vine to erect 

 a trellis standing out from six inches to a foot from the 

 building. This is generally constructed of wood, with 

 upright posts, and light, horizontal cross-bars. A neater 

 and less expensive way is to nail brackets, or arms, from 

 six inches to a foot in length, to the si$e of the building, 

 at suitable intervals, for the support of the horizontal 

 wires, which are to be fastened to the ends of the arms. 

 By keeping the vine at this distance from the building, 

 there is opportunity for the air to circulate behind the 

 foliage, and thus prevent dampness and decay. 



Should the system of horizontal branch - training be 

 applied to the side of a building, the grape-arm may be 

 secured horizontally to the building. In front of each 

 arm, and about on a level, two wires are to be stretched;
