There are thousands of situations where a supply of water, either from a spring or a running brook, may be introduced into a garden or grounds with great effect.

" Mildly and toft the western breeze

Just kissed the lake, Just stirred the trees,

And the pleased lake, like maiden coy,

Trembled, but dimpled not for joy;

The water-lily to the light,

Her chalice reared of silver bright".

In most suburban gardens there is sufficient space for a small aquarium; we know of several that are supplied from the village water-works, where a tiny jet is constantly playing, and refreshing the ferns and other moisture-loving plants dispersed among rooks and stones, goldfish disporting in a rustic basin below. If a space of only eight or ten feet diameter can be spared for the purpose, it will greatly add to the gayety of the scene from the windows. A circular pond of five feet in diameter may be surrounded by a border of rook-work of twelve or fourteen inches, the dark stones being merely loosely laid on an even surface, and beyond this a rim of turf two feet wide. The pond should be well puddled with clay, and over the clay a stratum of loam and sand; the rock-work should be formed of dark stones of small size; a light fence of iron-work or thick wire surrounds the whole, and on the turf about eight or ten standard rosea should be planted so as to form a ring, the little fountain throwing its jet from the apex of the central rooks (stones). The stones should be planted with one or two bushes of recumbent juniper; periwinkle, lyco-podium, stone crop, ferns, and some showy perennials, may be set in the crevices.

The) beauty of this little collection far excels a partem, and stands out brightly against the evergreens beyond.

A more extensive garden aquarium may be introduced at the base of a sloping bank, beyond which a mass of shrubs and trees secures shade and coolness to the lounger, and completes the picturesque character of the scene; it must be removed some distance from the house, deriving its chief beauty from repose, and the apparent absence of human dwellings. In such a scene, rustic arbors and seats, old tree stumps, crowded with mosses and ferns, are suitable ornaments, while the rookery itself may be converted into a garden for Alpine plants and ferns, the portions sloping towards the water being planted with marshy and aquatic plants, revelling in moisture under the shadow of alders and willows. An island and peninsula should not be attempted, unless the water covers a large space, and has its dimensions somewhat concealed by trees. It must be constructed according to correct principles to insure success; a concave hollow must be dug, of the needful dimensions, sloping steadily from the outer rim to a depth of not less than six feet in the middle.

Over the bottom must be placed a layer of puddled clay, six to twelve inches in thickness; above the clay, a layer of rich, sandy loam, or well-tempered soil from the bottom of a pond, must be arranged in circular terraces, like the seats in an amphitheatre, so as to form a series of shelves of various depths, from the margin to near the centre. On these shelves may be planted the aquatics, which are intended to be grown in the water. Thus you can place roots at various depths, so as to submerge each sufficiently, which you could not do on a slope, the pots being of course removable for renewal or change of plants, or during severe weather. In any case, the bottom must be of well puddled clay, and the mould above it a strong loam, with a surface of sand and pebbles. No one should undertake such a work unless thoroughly persuaded that he has force enough in himself or his assistants to keep it always in the best condition. Our engraving gives a sectional view of such a construction.
