distance from Coventry, though, in this case, the absence of some culminating 

 architectural feature to close the vista is much felt. 



The most important point in the formation of an avenue is that the trees shall be 

 chosen and arranged with due regard to uniformity in their size and habit when fully 

 grown. This is most difficult where one portion of the route is more exposed than 

 another to cutting winds, but much may be done by obtaining the whole quantity 

 required from one nursery and selecting individual trees for each position.

GRASS. 



All the remarks on the choice of trees for garden work given in another chapter 

 apply equally to those required for avenues, but, while in a smoky district or one where 

 towering height must be sacrificed for sturdy growth, the tap-root must be cut and the 

 leading shoot pruned at a later date ; in the open country there are many positions 

 where by far the finest result would be obtained by planting closer together and leaving 

 tap-root and leading shoot in their natural state. 



Arrange- The distance apart the trees should be planted in the rows at either side of the 



ment of avenue depends not only on the species to be used, but also on whether those on either 



trees. side of the roadway are to be placed opposite to one another as in the first sketch 



(No. 83) or diagonally as in the second (No. 84). The former arrangement is to be 



recommended where the surroundings of the avenue are restrained and conventionalized, 



and the latter where it passes through more or less natural scenery. The spaces between 



the trees in the former case would 

 vary from thirty feet for Lombardy 

 poplars to sixty feet for full-grown 

 elms, and in the latter rather less,

Where the scale of the mansion

warrant the greatest magnificence 



possible, double avenues, of four lines of trees, may be formed, especially where side 

 tracks for foot passengers are desired in addition to the central carriage drive. In 

 such cases, the two central lines of trees would be planted opposite to one another, and 

 the outer two, diagonally to the trees nearest to them (No. 85). Additional effect may 

 be obtained by pollarding the inner rows of trees and allowing the outer ones to tower 

 above them, an arrangement which will be familiar to those who know Chelsea Hospital,
