The first thing to be done when you have fixed upon your ground is to form the _walks_, marking them out by two garden lines, and then digging out the space between in the shape of an inverted arch, which should be from one to two feet deep in the centre. The arch is then partly filled in with brick-bats, stones, or any other hard rubbish which can be procured, leaving a little hollow space exactly in the centre to serve as a drain. Care must be taken, when filling in the rubbish, to put the largest pieces in first, then pieces somewhat smaller, and then pieces broken very small, which are rammed down as hard as possible, so as to make a smooth surface immediately under the gravel. The gravel before laying it down should be sifted, and all pieces larger than a moderate-sized gooseberry should be thrown on one side. As soon as the small gravel is laid down and evenly spread it should be rolled, and this rolling should be repeated occasionally till the walk becomes quite hard and firm. If the gravel does not bind well, it may be improved by mixing with it powdered burnt clay, in the proportion of one wheelbarrow full of clay to a two-horse cart load of gravel. The clay may be burnt by making it into a heap, intermixed with, and surrounded by, faggot wood. Gravel walks should always be slightly raised in the middle, in order that the water may run off on each side. If you should have an old gravel walk that wants renovating, the gravel should be loosened with a pick, turned over, raked, and firmly rolled, adding a coating of fresh gravel if necessary. If weeds should appear on a gravel walk, they are best killed by watering them with salt and water, and this liquid will prevent any other weeds from appearing. _Box edgings_ are the best for gravel walks, and March or April is a good season for planting them. The following is the mode of performing this operation, which requires some attention, as the beauty of the edging depends on its regularity. The margin of the bed for about a foot in breadth should be watered, and afterwards beaten firm and level with the back of a spade; a garden line should then be stretched along close to the walk, and a shallow trench opened, sloping towards it at an angle of rather less than 45°. Some dwarf box having been procured from the nurseryman, it should be divided into separate plants, and the branches and roots trimmed, so that the plants may be nearly of a size. These are laid along the sloping face as regularly as possible, with their tops rising about an inch above the soil, and the earth is drawn upon them, so as to fill up the trench and make them quite firm. The plants are then watered, and nothing further is required but to supply the place of any that may chance to die, and to keep the tips neatly trimmed.
