Ivy or ornamental creepers may be grown on the wall having a northern exposure; and almost any kind of plant thought desirable may be cultivated in the interior of the garden; provided such trees or shrubs as may be planted there are not allowed to grow to such a height as to shade the peach wall.

At b b two pairs of houses are shown; the fronts of which are also parallel to a north and south road, and the gardens of which have nearly the same advantages as those shown at a, except that a small portion of the garden of the house next the north will be in the shade during the greater part of the winter season; as shown by the triangular shadow thrown upon that garden in the diagram.

At c are two rows of houses similar to those at a; but, as their direction is south-west, the sun will shine on both sides of these houses, and both on their front and back-gardens, every day on which he appears, throughout the year.

The small proportion of shadow which these houses will throw upon their gardens may be considered as represented by the triangular masses of shade on the front gardens on one side of the road, and on the back gardens on the other. The actual shadow thrown by a row of connected houses on the ground, would, of course, be a parallelogram, and not a series of triangles; but our object in giving this diagram is not so much to show the actual shadows that will be thrown at any particular time upon the ground, as to indicate the proportion of shadow which one position of the house and garden fences will throw on the ground relatively to what will be done by another position. In the double detached houses, b, d, f, etc, the proportion of shadow which we have shown in the diagram also indicates the part of the garden which will be most in shade throughout the year. The walls of those gardens which have a south-east exposure, will ripen figs, apricots, and the finer plums; while those having a north-west exposure, may be devoted to currants or morello cherries; or to roses, and the finer kinds of ornamental creepers.

At d, on both sides of a road in the same direction, are shown double detached houses, the gardens of which have similar advantages to those at c, but increased in consequence of the houses being detached, and their diagonals being south and north, which admits of the sun shining all round them on every day on which he appears.

At ff, on a road in the direction of south-east and north-west, are shown double detached houses, square in the plan; the diagonals of which, being directly south and north, their exterior walls and their gardens will have nearly the same advantages as those of the houses shown at d; but with this difference, that a wall having a south-west aspect is not considered quite so good for ripening the finer fruits, or growing the more delicate creepers, as one facing the south-east.

At g are shown two rows of houses on the north and south sides of a road running east and west; by which it will be seen that the front or street gardens of the houses on the south side of the road, will be entirely in the shade during the greater part of the winter; while the gardens behind these houses will be entirely in the sun throughout the year. As the side walls of these gardens (at h) can only enjoy the sun one half of every day, neither of them are fit for ripening the finer fruits; but both of them will grow plums and cherries, and both are admirably adapted for ornamental climbers. Against the wall at the farther end of the garden, which will be in the shade almost every day in the year, ivy and some very hardy climbers may be planted, such as the Virginian creeper and the Ayrshire rose: and against the house at the opposite end, which will be fully in the sun every day in the year, may be planted a vine and a fig; the latter to cover the lower part of the wall, as high as the first-floor windows, and the former to clothe the upper part as high as the roof.

The walks of such gardens will be equally dry on both sides of the garden, because one boundary wall does not throw more shade on the walk running parallel to it, and near it, than the other; and, provided the cross walk at the south end is kept at such a distance from the end wall, or boundary fence, as not to be shaded by it, it will be as dry as the side walks. Hence, these gardens are more favourable for invalids to walk in during winter, and immediately after rains, than those can be where one of the aide walks is chiefly in shade, as will be the case in the gardens of the houses at a a. The front gardens of the houses on the north side of this east and west road will enjoy the sun throughout the day during the whole year, and are, therefore, unless the road is very dusty, suitable for the culture of the finer flowers and shrubs. The gardens at i, behind these houses, are, however, the most unfortunate of all in point of aspect; for one half of them will be entirely under shade during the whole of the winter months, and also during a considerable portion of both the spring and autumn.

Only the small portion of wall at the bottom of this garden, which forms the end of it, is fit for the finer fruits; the remainder should be covered with ornamental climbers: and the walks, during the greater part of the year, will unavoidably be cold and damp.

At k are shown two pairs of houses, one on the south and the other on the north side of an east and west road, which partake more or less of the character of the houses shown at g: but the two gardens at m, being open and airy, will be very suitable for taking exercise in throughout the year; and a vine or a fig may be placed on the south side of the house. The gardens at l will not be much inferior to those at m, in consequence of the sun being admitted to the sides of the house as well as to its front. In this case, as in the gardens of the houses at d, b, and f, the great advantage of detached houses, in point of the enjoyment of the sun and air, is obvious.

Single detached houses, it will be sufficiently obvious, are subjected to the same laws respecting shade as detached houses which are in pairs.
