The idea generally prevails, that tlie system of vines placed above each other in the 

 manner shown on page 22, constitutes the entire Thomcry jjlan of training, whereas, it 

 jnly constitutes one of the most important members of the princij)al section. The 

 entire Thomery plan is a vine garden in the form of a parallelogram, the dimensions 

 of which, for illustration, may be stated at two hundred feet in length by fifty in 

 breadth, having its length in an easterly and westerly direction, so that the principal 

 sheltering wall may have a southerly aspect. The most favorable exposure for a cold 

 or temperate latitude is south-east, being that afforded by the wall running nearly north- 

 east and south-west. 



The hight of the wall, on the north or northerly side, is generally about nine feet, 

 and in exposed situations, one or two feet more or about two feet higher than that of 

 the ends, while in all cases the wall of the southerly side does not exceed six feet, un- 

 less to protect from intrusion. 



The principal or northerly wall, and about twenty feet in front of it, are occupied by 

 five rows of vines, as shown in the engraving, Plate No. S3, page 36. The principal 

 row is trained upon a trellis that is fastened to the wall, but from six to nine inches in 

 advance of it ; the last distance is not too great. 



The remaining thirty feet is occupied by a system of walls less elevated, on which 

 vines are trained, some running parallel and some at right angles to the northerly wall, 

 for a full account of which see Landmaeks. 



The outer walls are called walls of inclosure, and the others walls of shelter, 

 although the walls of inclosure, and especially that on the north, are even more walla 

 of shelter than those which perform no other office.
