The boundary fences of the front garden may be planted with gold and silver-leaved ivy, intermixed with a plant or two of the common ivy; and the boundary fences of the back garden may be wholly planted with either the common or the giant ivy, or with a mixture of both. In the centre of the lawn, in the front garden, may be planted a laurestihus, an arbutus, a phillyrea, an aucuba, a double-blossomed furze, Cotoneaster Uva ursi, a common tit variegated box, an evergreen rhododendron, or some ether compaet growing hardy evergreen shrub, which may be selected from the descriptive catalogue of hardy evergreen shrubs which we shall give in a future page; or a deciduous flowering shrub may be substituted for an evergreen tree, if there should be chiefly evergreens in the adjoining gardens; Among the beautiful deciduous shrubs of moderate growth which require little or no pruning add management, may be mentionedthe Cyddnia japonica (either the pale or the deep red-flowered variety, or a plant of each put into one hole)) the Persian lilac, and the Ribes sanguineum. Of all these plants the two most suitable are the laurestinus and the Cydonia japonica, because neither require any pruning, and both flower in the winter season.

As these plants, however, from their beauty, cheapness, and easy culture, may possibly be common in the Adjoining gardens, if expense should not be an object, one of the evergreen berberries or mahonias, such as Ber-beris dealbats or Mahonia Aquifolium, or Garrya elliptica (a valuable winter shrub), may be selected as the evergreen; or, if a deciduous shrub be pre-ferred| Spiraea ariaefolia, or S. bella, or some other species of that genus, or a yellow azalea, may be substituted. These comparatively rare evergreen and deciduous shrubs are as hardy as the others; and, like them, require ho pruning whatever, further than cutting off dead wood or dead flowers; But if all the Adjoining front gardens are planted with the more rare and beautiful foreign trees and shrubs, and the occupier should have the laudable desire of increasing the general variety in the street, he may step from the garden into the fields, and place in the centre of his grass plot, for ah evergreen, the common spurge laurel) or the double-blossomed furze; and for a deciduous shrub (if he should prefer one), the spindle tree, or any dwarf British willow, may be made choice of.

Should even these be already introduced, he may have recourse to the pine and fir tribe, and take one of the dwarf Varieties of the common spruce, such as Abies excelsa Clanbrasilsans, or a dwarf pine, such as Pinus sylvestris pumilio, or P. s. Mughus.

95. In the back garden, We would merely introduce a few standard low flowering trees, or fruit trees, placing them along the centre of the lawn, that they may not interfere with the walks, along the lawn side of which clotheslines will probably occasionally be placed in the manner before mentioned. (§ 79.) The tree nearest the house should be a double-blossomed hawthorn, because it comes sooner into leaf than any other low tree, and the flowers being double, are not Succeeded by fruit, so that the tree is in no year so exhausted but that it can flower abundantly the year following; whereas a tingle-blossomed thorn, or tree Of any kind in which the flowers are succeeded by a large crop of fruit, seldom blossoms well two years in succession. Such trees, therefore, should never be chosen for points of view where it is wished to have a fine show of blossoms every year; but rather trees which, like the above-mentioned variety of thorn, bear double blossoms. The next tree may either be a Pyrus spectabilis, or transparent or Siberian crab, or some description of apple which has showy blossoms and bears abundantly, such as the Hawthornden. The third tree may be a perfumed cherry, standard all-saints' cherry, double-blossomed cherry, an almond, or a Cotoneaster frigida, C. affinis, or some similar tree, which may be selected from the catalogue of hardy trees and shrubs given hereafters The nest tree may be a mulberry, which thrives and bears abundantly in the very heart of London, and which should always be planted on grass; because, as the fruit drops the moment it is ripe, it can be picked up clean for use, which it cannot if it falls on dug ground or gravel.

The two succeeding trees may be a laburnum and a scarlet thorn; or, if the occupier prefers fruit trees, they may be two pears, say a glout morceau, and a Marie Louise, or abeurre de Capiaumont; or they may be two plums, or cherries: or, if he prefers evergreen trees, they may be two variegated hollies. We recommend the variegated holly, because it is one of the most cheerful of evergreens, and is in no danger of growing out of bounds, so as to require pruning. Next to it, for the climate of London, the cedar of Goa may be planted; but, as the cedar of Goa is somewhat tender, perhaps a preferable plant for a smoky situation would be the Quercus ilex, of which the willow-leaved and beech-leaved varieties may be selected; or, for colder climates, the common red cedar. We have here shown only one line of trees down the centre of the lawn, because they will there have abundance of room: they will not require pruning for many years, and their leaves will drop on the grass, and not litter the walks.

When low-growing trees are planted near the walks, their branches hang over them; and every year those which inconvenience persons passing along the walks require to be cut off, or tied up, and this would occasion expense in keeping, which it is one of the desiderata in this mode of laying out and planting to avoid as much as possible. For this reason no tree or shrub is directed to be planted against the house, because that would be to incur the expense of training and pruning. The trees should be procured of 6ft. or 8 ft. in height, so that their tops may be, when planted, out of the reach of injury from children; and the grass may either be sown, or turf may be procured and laid down. The latter produces the more immediate effect, though it is by much the more expensive, and, in the end, the turf is inferior, from its usually containing a mixture of unsuitable grasses and broad-leaved plants. The grass seeds will produce a close verdant surface in about three months, and, in a year, a much finer lawn than turf brought from common pasture, or meadow, or an old grass field. The flagstones or slates should be laid on brick piers, built on a solid foundation; so that their surface may be at all times level and even at the joints, for walking on.

The surface of paved walks, like that of all others, as far as it is practicable, should be rather higher than the adjoining surfaces: otherwise, in heavy rains, they become receptacles for water, which, being often muddy, disfigures the stones, the pavement, or the gravel: but on this subject we shall enter more at length, when treating of walks, in a future page. If the shrub planted in the centre of the front garden be one of the more rare kinds, the natural loam, which we have supposed to be the soil in both gardens, may require to be mixed with a little sand, peat earth, or vegetable mould, to lighten and enrich it The kinds of grass-seeds proper for sowing the lawn, and the mode of procedure, etc, will be given in a future page.

96. The expense of carrying into execution this manner of laying out and planting a suburban garden will depend chiefly on the price of flagstone or paving slate. In London, this, taking a quantity of the material together, would he from 4d. to 6d. a foot; so that every foot in length, of a walk 3 ft. broad, would cost from 1s to 1s. 6d., independently of the expense of building the piers by which the flagstones are to be supported. The whole expense of making these walks will be about three times that of walks laid with gravel: but the saving of expense in after-keeping will be so very great, that no one who can afford the first cost will ever consider that as a reason for not haying them. If preferred, the walks may, however, be of gravel or asphalte; directions for making which will be given hereinafter. The trees will cost 2s. 6d. each, and the grass seeds for both gardens 2s. 6d. The whole expense of laying out and planting, including the paving, may be between 20l. and 30l.

97. The expense of keeping a garden so laid out and planted, even if it were 200 ft. long and 50 ft. wide, would not cost, in the neighbourhood of London, 20s. a year; and yet it would at all times look neat. The ivy would grow up against the walls, and cling to them, without any expense of nailing or pruning, except when it infringed too much on the lawn in the front garden, or on the walk in the back garden, which it would not do for ten or twelve years, but it might require to be trimmed a little at the roots once a year. In consequence of there being no box or other planted edgings, there would be no expense of keeping them in order, and occasionally renewing them; and the margin of the lawn would only require to be prevented from spreading over the flagstones, by clipping the grass with a pair of shears every time the surface was mown. Neither the trees, nor the shrubs in the front garden, would need any pruning whatever for ten or twelve years, except the cutting out of such dead wood as might appear among the branches. We do not say that the fruit-trees would not be improved by pruning, but merely that, as far as neatness of appearance is concerned, it would be quite unnecessary.

The walks would be cleaned by every shower of rain, and would not even require sweeping, except when the edges of the grass were clipped. The sole expense would thus be that of mowing the lawns and clipping their edges, which might be done six or eight times in the course of the year, at 2s. or 2s. 6d. a time; or the occupier, or his servant, might cut the grass with Budding's mowing-machine, and the edges with a pair of small hedge shears.

98. In planting a garden of this kind in a situation exposed to the smoke, care should be taken to use only those kinds of trees and shrubs which will thrive in close situations, as there are some kinds of shrubs and trees which experience proves will thrive even in the midst of smoke. Thus, for the plot in front, we should recommend Aucuba japonica as an evergreen, because this remarkable plant, though a native of Japan, endures the smoke of London better than any indigenous evergreen shrub whatever; and, as a deciduous shrub, the common purple lilac, which is both hardy and beautiful, and comes early into leaf. The trees in the back garden might be the double-blossomed and scarlet thorns, both of which will grow and look well for at least eight or ten years; the laburnum, the almond, the mulberry (which thrives admirably in the most smoky places), and the weeping or allsaints' cherry (which is one of the few flowering trees that prosper in the gardens of Lambeth Palace, though enveloped in the smoke of numerous houses and manufactories). Ivy, whether common, giant, or variegated, will thrive in the very heart of London. Grass will not live, and look well, in smoky situations, for any length of time; but, if the Poa annua be used, it will ripen its seeds and sow itself every year; and it has this advantage, that daring winter it is greener than any other grass that will grow in a town.

Should it fail in any part, and leave bare patches, seeds may be procured from the seed-shops, and, being sown at any season, will come up in a few days.
