ON THE PRODECTION OE EEEECT IN LANDSCAPE AND GARDEN SCENERY. 
By Mr. JOHX COX, Gardexer to AY. AYells, Esq., Redleaf. 
7N the higher branches of the art of Gardening, or such as require the application of a well- 
X educated taste, the production of effect may he considered as the great desideratum to which the 
efforts of the designer should be directed. It matters not what are the means employed, or the parti¬ 
cular parts operated upon, the end is obvious—-viz., to produce an appearance which shall strike the 
observer ; and in proportion to the skill and taste employed, so will the effect he pleasing to the eye 
by its beauty, agreeable to the taste by its consistency, and striking to the imagination by its novelty 
and judicious contrasts ; or, otherwise, formal, commonplace, and unnoticable. 
Many good remarks bearing on this subject have from time to time appeared in the Gardener 1 s 
Macja zine of Botany ; but it appears to me to be one deserving of greater consideration—indeed, of 
so much importance as to be worthy of having especial attention drawn to it: for it is undoubtedly 
the leading idea which should occupy the attention of the designer and improver, whether of Land¬ 
scape, Lawn, or Flower-garden scenery. It is also applicable to the arrangement of plants in conser¬ 
vatories, or wherever then' agency is employed for decorative purposes.
