that the trees ou both sides must be planted opposite to each other. 

 The trees ought also to be of the same height, the same size, and, 

 as far as practicable, of an equal degree of vigour ; for if they differ 

 materially in the latter respect, some will grow more freely than the 

 others, and in the course of a few years the lines will present an 

 uneven appearance. But with ordinary care in selectmg the trees, 

 and a little regulation of the growth when needful, there will be no 

 difficulty in keeping all the trees to precisely the same shape and size. 

 The trees which can be the most strongly recommended for 

 promenade walks and geometrical schemes are — 



Ouriressstis Lawsouiana, a handsome tree of medium growth, emi- 

 nently suitable for rather broad walks, cheap, and thriving m ordi- 

 nary soils. , 

 Cupressus Laivsoniana ereda viridis is a fine torm ot the preced- 

 ing ; in growth more erect, and in colour of a much brighter green ; ■ 

 it is one'of the finest of promenade trees. 



Cupressus Lamoniana argentea is less erect than either of the 

 preceding, and forms roundish and dense specimens ; the tips of the 

 shoots silvery, and drooping gracefully. 



Juniperus chinensis, a hardy and beautiful tree of medium growth, 

 and elegant pyramidal habit. 



Junipems excelsa stricta, a beautiful small growing tree, with a 

 neat pvramidal habit and glaucous green foliage. 



Juniperus comvmnis hihernica is the Irish juniper, well known 

 for its upright columnar habit; it can be clipped and kept to a 

 small size, and is, therefore, well adapted for terrace promenades. 



Juniperus liispanica has a dense pyramidal habit, and is very 

 handsome when from four to six feet high. 



- Lihocedrus decurrens, a rather robust tree, columnar m growth, 

 and exceedingly handsome, resembling in some respect a gigantic 

 lycopod. The colour is exceedingly rich. 



Retlnospora ohtusa is a hardy and most elegant tree, forming 

 dense roundish specimens ; but it is not so generally useful as the 

 other things mentioned. 



Taxus fastigata ia the Irish yew, so well known for its columnar 

 habit, and is one of the best trees for promenades and geometrical 

 gardens. It can be clipped to form neat columns three feet in 

 height, or it may be allowed to grow into specimens twelve or fifteen 



feet high. , 



Taxus japonica is similar in character to the preceding, Dut 



d.wfl.ricr. 



Thuja LoUi, a handsome tree of upright growth, somewhat 



similar to Lihocedrus decurrens. 



Thuja orientcdis aurea is dwarf and distinct in character, it torms 

 dense round bushes, and is one of the finest of its class for geome- 

 trical gardens and terraces. The young growth has a golden hue in 

 spring, and the plants are then very attractive. 



Thuja orientalis elegant Issima difi"era irom the preceding in being 

 of a more erect and columnar habit. 



Thujopis borealis, a fine upright evergreen, of rather free growth, 

 and exceedingly handsome for broad promenades.
