As I have already alluded to the improvement that will be effected by introducing a shrubbery to harmonise the intended flower-garden with the trees in the park, you will probably wish to know if any thing of the kind will be required on the back-front of the house; but in that case there will be less difficulty, as the terrace affords an admirable medium for uniting the architectural stiffness of a mansion with the beautiful wildness and grace of nature. There is always a degree of incongruity in passing abruptly from the stiff symmetrical forms of a building, to the unsymmetric, though graceful, forms of a tree left in a state of nature; and it was no doubt a feeling of this kind which induced our ancestors to surround their houses with formal architectural gardens and trees clipped into stiff and regular forms. In more modern times something of the same kind was done, by always adding to the house verandas, porticos, and terraces, which formed a connecting link between the building and its grounds. After a time these also were laid aside; and about the beginning of the last century, when Brown and his followers would admit nothing but what they called nature in garden scenery, the park was allowed to come close up to the windows of the house, and, as a writer in the Gardener's Magazine observes, the inhabitants of the mansion might "leap from their windows into jungles, and steppes, and wildernesses, where the lion and the panther would be more at home than the lady in her silken sheen."
You will see from these observations that there are styles marking different periods in gardening, as well as in architecture; and, in some cases, it is advisable to preserve a certain degree of similitude between the style of the garden and that of the house. Of course, however, this can only be done as far as is consistent with modern comforts; and the fact of your house being partly Elizabethan does not entail upon you the necessity of having a formal garden with high clipped hedges, and trees cut into a thousand fantastic forms, any more than it obliges you to sit in rooms darkened by stone mullions and small-paned casements, because the courtiers of Queen Elizabeth were obliged to submit to such inconveniences. With regard then to the back-front of your mansion, I would leave the terrace in its present form, with its stone alcoves at each end, as it corresponds so well with the style of that part of the house which appears to have been added in the reign of Anne or George I.; and I would preserve and repair the stone balustrade with urns at regular intervals, and the stone steps leading from the terrace, which are all in the same style as the house; I would also have them lead into an architectural garden below. The form of this garden should be quite regular, or, if you prefer the term, quite formal; and it should be ornamented with fountains, urns, and statues. The natural boundary of this garden is the piece of water before alluded to, the borders of which should be planted with a few tufts of shrubs to break, but not disguise, the regularity of the outline. On the other side of the water these tufts must be continued, but in a much wilder and more natural manner; and here and there the plantation must take the character of a clump, and consist of low trees, mingled with shrubs of the largest size. This will unite the house and garden with the park scenery as regards the view from the drawingroom windows, and on the side of the garden, gravel walks may be carried on through the various scenery of the park, a stone bridge being thrown over the water on the side nearest the entrance-front; and, farther on, a rustic bridge may be thrown over the stream in a situation where it is not seen from the house.
I think it very desirable that openings should be made in several places through the mass of wood, to admit views of the distant scenery from the drawingroom; as, for instance, if there is a church or a tower, or any other object that would form a suitable termination to a vista. In the reign of William and Mary, when the Dutch style of gardening was fashionable, nothing was more common than long vistas of the kind called patte d'oie, all springing in rays from one point, and each terminating in some ornamental object, such as a temple, an obelisk, or a statue. Some slight approximation to this style, by cutting long vistas through your woods, might therefore be very consistently introduced wherever a suitable occasion for it may occur.
In planting your architectural garden, you must observe that it should have rather a different character from the small garden in front of your sitting-room window. The architectural garden should contain standard rose trees, almond trees, double-blossomed peaches and cherries, the Chinese magnolia, or yulan tree, and other showy-flowering trees, planted in company with arbutus, phillyrea, Minorca box, and other evergreens of a similar character. In the shrubbery, at each end of the garden, but not forming part of it, these trees should be continued, and mixed with variegated hollies, the different kinds of Cratæ'gus, and other trees that are ornamental, and that never attain a large size.
I have already suggested that in various parts of the pleasure-grounds advantage should be taken of any natural inequalities that may exist, to form different scenes; and I have now only to add that advantage may be taken of singular peculiarities, should you wish to form in your grounds one of those arboretums which are now so fashionable.
An arboretum is a collection of trees and shrubs, in which all the different species of natural order are planted together; and it does not necessarily imply that these orders should be arranged in any particular manner; as indeed botanists are not agreed as to how they should be placed, Jussieu having adopted one plan, De Candolle another, and Dr. Lindley another. The only essential point is, that all the plants which agree sufficiently to form an order should be placed together; as, for example, all the Coníferæ or cone-bearing trees, such as the pines and firs, the cedars, the cypresses, and the junipers; and all the Cupulíferæ or nut-bearing trees, such as the oak, the chestnut, the beech, and the hazel. Thus in your grounds, where there is a valley, it may be formed into what is called an American ground, consisting of the shrubs allied to the heath family, and planted with rhododendrons, azaleas, kalmias, and other similar plants. A glen may be planted with pines and firs, so as to form it into a kind of pinetum; and an open space among trees may be turned into a rose-garden or rosery. In this way most of the exotic trees and shrubs that will stand the air in English gardens may be planted in groups, without going to much expense, and with less formal appearance than that of a regular arboretum. Besides, the beautiful colours which some of the exotic trees will take in autumn give them a splendid appearance, when they are backed by other trees with verdant foliage.
The rose-garden will be a very beautiful object if skilfully arranged; and, by thus forming your park into a succession of scenes, you will not only increase its beauty in the eyes of strangers, but add very materially to your own enjoyments by increasing the objects of interest within your reach.
I do not suppose you will have any occasion to renovate the turf in any part of your park; but, if you should, the best way is to get a mixture of the seeds of several sorts of grasses, such as the fox-tail meadow grass (Alopecùrus praténsis), the sweet-scented vernal grass (Anthoxánthum odoràtum), the crested dog's-tail grass (Cynosùrus cristàtus), and other valuable kinds. If ever you find a patch of grass has become bare, have an iron rake drawn over the ground two or three times, so as to loosen it, and then sow a few seeds of the grasses I have mentioned, when the ground is in a tolerably moist state from rain. This will generally be sufficient; but if it should not, as the seed of the fox-tail meadow grass is very often bad, you have only to add a little seed of the common white clover, and the ground will appear green in a few days.
