Vines are planted at greater distances than ordinary, and the 

 number diminished, the vacancies are supplied by planting 

 others on the back or contrary side of the wall, and intro- 

 ducing them to the front through apertures. The plan is 

 exemplified in the following Figure.

The treillage against the walls is formed of upright rails, 

 placed at the distance of eighteen or twenty inches apart ; 

 to these are attached horizontal bars, nine inches from each 

 other ; the lowest bar being six inches from the ground. Each 

 Vine occupying no more than one cordon, and the most 

 suitable distance between each cordon being found to be 

 eighteen inches, a wall of eight feet high will contain five 

 cordons ; and the five Vines planted for the purpose will, 

 at twenty inches apart, cover a space of the wall about eight 

 feet in length.
