328 APPENDIX II. 



scorched that the distance of 20 inches between the stocks is 

 not sufficient to allow the roots to gather from the earth the 

 nourishment required. This distance must then be increased, 

 without however augmenting the length of the cordons. 



When the position to be given to the cordons is properly de- 

 termined, the plan of their arrangement is traced upon the wall. 

 Begin by indicating at the foot of the wall from A to J (Fig. 70) 

 the point from which each shoot should spring, and from that 

 point draw a vertical line. 



At the point A, this vertical line ceases at the height of the 

 first cordon at 15 inches from the soil ; at the point B, 83.08 

 inches ; at the point c, at 50 inches, and as far as the point E, 

 where the line of the first cordon ceases at 86 inches from the 

 soil. From thence a second series of lines is commenced simi- 

 lar to the first, and we proceed in this manner to the end of the 

 wall. It then only remains to trace, touching the top of each 

 vertical line, the course to be taken by the cordons from 

 right to left, and to indicate where each of them is to cease 

 that is to say 4 at 52 inches from each side of the main stalk. 

 After the conclusion of this operation, the vines are planted in 

 the manner which we intend to describe. 



HORIZONTAL COKDOX OF CHARMEUX (Fig. 72). The arrange- 

 ment which we have just explained is that which was at first 

 generally adopted for the Thomery vines, and is that which is 

 still employed for the trellis of Fontainebleau. But it was not 

 Jong before the cultivators of Thomery remarked that this 

 method presented an important inconvenience. During the 

 formation of the cordons, an entire arm of each stock is shaded 

 by the upper cordon, while the greater part of the opposite arm 

 escapes this unfavorable influence. The result is an inequality 

 of growth between these two arms, and it becomes necessary to 

 employ certain processes, often unavailing, to maintain a pro- 

 per equilibrium of growth between the two arms from the 

 main stalk. To obviate this difficulty, in 1828, M. Oharmeux, 

 senior, invented a new description of horizontal cordoti, which 

 has been adopted by almost all the cultivators of Thomery for the 

 trellises which they have since erected. The plan is as follows :
