hills. We are familiar with gardens in which both this and a contrary course 
have been adopted, and some, also, wherein only a fertile glen or level is employed. 
The results, as far as they have yet been manifested, uniformly confirm our 
previous declarations. 
Lest it should be imagined that the effect on vegetation of a difference of 
temperature between hills and valleys is solely absolute, or arising entirely from the 
intense coldness of the atmosphere, we shall rectify any such partial view. From 
the greater humidity of the air and soil, and the diminished agency of sun and wind, 
plants in low places are always more charged with moisture, and their growth is 
more exuberant and less mature, than those which inhabit hilly tracts. Hence, in 
addition to the increased amount of frost to which they are liable, they possess within 
themselves the means of rendering it more destructive. We would now expressly 
caution every cultivator against planting tender species either in valleys or very 
expansive plains, and press upon them the importance of choosing an open inclined 
surface for naturalizing exotic plants.

Few gardens are destitute of that most delightful feature of the pleasure 
grounds, a glade of turf : now spreading uninterruptedly in its pleasing verdure, 
and swelling into varied undulations, or assuming a level sweeping aspect ; and 
anon profusely dotted with isolated shrubby, or arboreous ornaments, or diversified 
clumps and plots. If tastefully disposed, the trees or groups scattered over it will 
form occasional shady recesses and retired nooks, through which the glow of a 
summer"'s sun and the rigour of the wintry blast will alike find it difficult thoroughly 
to penetrate. 
There will be other spots, again, which are secluded from cutting winds by 
their depressed position, and the protection of surrounding trees, but which present 
a more ample superficies, and admit a much greater glare of light, the influence of 
which last is modified by the vicinage of the highest forms of vegetation, and the 
partial concavity of the surface. 
Still further, shrubbery walks, bounded by broader or narrower masses of turf, 
will be carried round the whole, or across some of its less interesting portions ; and 
in these grassy outlines, occasional breaks or exjDansions will occur, both to alleviate 
the monotony of long, confined walks, and allow the introduction of handsome 
flowering shrubs. 
All these situations affbrd the precise kind of shelter and shade requisite for the 
sort of shrubs we are about to notice, and which consist of low evergreens that do 
not all positively demand such conditions, but, for the most part, thrive best when 
they are secured. The plants we refer to are the better varieties of dwarf Rhodo-
