229. The boundary walk, or fences, of the garden, of whatever kind these may be, can hardly fail to require some repairs. If they are brick walls, on which trees have been trained for many years, the bricks will be full of nail-holes, and their joints will be found open from the falling out of the mortar. The common mode of remedying this evil is to repoint the wall; that is, to fill up the interstices between the bricks with fresh mortar, replacing any greatly damaged bricks with new ones: but, as this is attended with considerable expense, a cheaper and more effectual mode is to brush over the entire wall with a mixture of Roman cement and water, as thick as it can be laid on with a brash. The wall having been previously brushed over with water to clear it from any loose materials, the mixture should be instantly applied; and it should be used as soon as made, or it will set in the vessel it was made in. If one coating of this liquid cement be not sufficient to fill up the holes, a second may be given, after the first has been two or three days laid on; or even a third, if necessary to render the surface of the wall tolerably even.

An old dilapidated brick wall, in the Horticultural Society's Garden, was treated in this manner upwards of twelve years ago, and has ever since been almost as good as new. The coping of walls should be examined and rendered watertight; otherwise, the water will be liable to get into the heart of the wall, and rot it For the repair of copings, cement is admirably adapted; and, even if the coping should require to be entirely renewed, plates of artificial stone, formed of cement, will, in many situations, be found cheaper and better than any other. When a wall is in a bad state, and it is not considered desirable to bestow much expense in repairing it, the cheapest mode that we know of for keeping it standing for a great many years is, to plant ivy at its base, and alios- it to run up; in which case the ivy will not only protect the sides of the wall, but will form a mantled coping to its top. When the boundary fence is of wood, it should be examined, to ascertain whether the parts are rotten "between wind and water" (that is, at the surface of the soil), which is very frequently the case while the tipper pert of the fence is fresh end strong.

In this case, the posts should either be entirely renewed, or the cheaper mode adopted of inserting fresh posts dose to the rotten ones, of each a length as to reach two or three feet above the surface. By nailing these short new posts to the sound pert of the old posts, the fence may he kepi up during another lease. A full-grown hedge, with gaps in it, it one of the worst fences to repair; because young hedge-plants will never thrive among old ones. The only mode, in this case, is to intertwine the adjoining branches, and to insert stakes for retaining these in their position. The hedge will often be found too broad at top; in consequence of which, the light and air are too much excluded from the bottom, which becomes naked; and here the only remedy is to cut in the sides of the hedge, so as to reduce the width at top; when, after two or three years, it will become equally thick from the ground upwards.

280. The walks, whether of gravel or pavement, will hardly fail requiring to be taken up and replaced or renewed; and, as the underground drains are generally along the sides of the walks, both may be renovated at the same time. The edgings to the walks, if of box, will probably be overgrown; in which case they will require to be taken up and replaced by young plants from a nursery, unless the occupier be content to take up the old box, and plant it in rows in the interior of the garden, in the manner called by gardeners laying in, leaving only an inch or two of the plant above the surface, in which state it will commonly throw out fresh roots from the side shoots, and, in a year, be fit to plant out along the walks as edgings. Some gardeners plant old box at once as edgings, where it is finally to remain, burying the plants to within 2 in. of the ends of the shoots; but as, from the length of the old overgrown box, it becomes necessary in this case to bend the plants in planting them, and, consequently, many of them are broken, and thus are liable to die during the summer, it is better to make certain of plants that will live, by rooting the box first in nursery lines, as recommended above.

In almost every case of renovation, of whatever material the edgings to the walks may have been made, whether grass, thrift, strawberries, brick, tile, slate, or stone, they will require to be taken up and replaced, if not renewed.

231. The turfy if there be any, if it does not require the surface on which it grows to be relevelled, may be renewed by digging it down, forming and consolidating the surface by raking and rolling, and afterwards sowing grass seeds; or, if expense be not an object, fresh turf may be procured from an old pasture. In many cases, however, all the renovation that will be required for turf will be the filling up of the inequalities of the surface with fine soil rolling the whole firmly, and sowing grass seeds in the bare places after the first shower; then slightly raking it, and again rolling it after it becomes dry.
