To design and execute a scene in either of these styles of imitative art, the artist would require to have, to a certain extent, the eye of a landscape-painter; the science of an architect and of a botanist; and the knowledge of a horticulturist. Every part of nature, whether rude or refined, may be imitated according to art For example, an old gravel-pit, which had become covered with bushes and indigenous trees, and contained a hovel or rude cottage in the bottom, with a natural path worn in the grass by the occupants, would be improved according to imitative art, if foreign trees, shrubs, and plants, even to the grasses, were introduced instead of indigenous ones; and a Swiss cottage, or an architectural cottage of any kind that would not ho recognised as the common cottage of the country, substituted for the hovel. To complete the character of art, the walk should be formed, and gravelled, at least, to such an extent as to prevent its being mistaken for a natural path. Rocky scenery, aquatic scenery, dale or dingle scenery, forest scenery, copse scenery, and open glade scenery, may all be imitated on the same principle; vis. that of substituting foreign for indigenous vegetation, and laying out artificial walks.

This is sufficient to constitute a picturesque imitation of natural scenery.
