There are so many different designs of garden architecture that it is of very little use trying to describe any particular form. I would recommend, however, that the design chosen be as simple a one as possible. The flower-beds should be made of rather a large size, and afterwards may be planted with roses, and herbaceous and bedding plants; they will also serve the additional purpose of containing the clipped trees. I do not, of course, mean that all the beds should be of uniform size or shape; but the beds in which trees are to be planted should be from twenty-five to forty feet in length, and from five to seven feet wide. A bed of these dimensions will be found to answer all purposes fairly well, whatever be the design adopted, and whatever shape may be given to the beds themselves. All the paths, with the exception of the main walks between the quarters or divisions, should be grass; and those main walks should have a substratum of some hard material and be covered on the surface with loose gravel. Some objection may be raised to grass walks as being of an unserviceable nature for general garden work; but, if the main walks are made as suggested, the amount of work and trampling on the grass paths will be reduced to very small proportions, and even when necessary to do any heavy work over the latter, such as wheeling manure or other traffic of a similar nature, dry or frosty weather can usually be chosen as the most convenient moment. [Illustration: OLD-FASHIONED BOX GARDEN, CHASTLETON HOUSE ] In making the flower-beds, box should always be used for edging; never stones or ornamental tiles, as anything of this description is altogether out of keeping with the general features of a Topiary garden. There may be a slight objection to box edging on account of the difficulty of getting it to grow well in certain soils. Generally speaking, I have never had the slightest difficulty in getting it to flourish and remain in a healthy condition, provided it gets proper treatment. I have some boxwood at Levens which has not been relaid for nearly, if not quite, a hundred years; and yet it is in a strong, healthy state. When the portion of the garden intended to be devoted to Topiary gardening has been laid out, attention should be given to the other portion of the grounds; and, as none of the old formal gardens were considered to be complete without a bowling-green and hedges of yew, horn-beam, or holly, a bowling-green should be made and then enclosed by one or another of these species of hedge.
