A Passage Garden forming the approach to the principal rooms of a large property often occurs as an accidental necessity of the site; but occasionally a narrow strip of land is purposely arranged in this manner, with the chief object of commanding a distant prospect. In the latter case, the enclosing fences are kept low, and the surface strewn with gravel and ornamented chiefly with flowering plants, avoiding the use of high shrubs or trees calculated to obstruct the view. The level area of a Passage Garden generally consists of beaten earth or clean sand, having a pathway formed of stepping stones of various shapes. Examples, however, are common in which these foot-stones are embedded in a concreted or cemented surface. Here and there, at the sides and in the corners of the enclosure, are introduced rocks, stone lanterns, and groups of trees or shrubs. The angle nearest the west should always be planted with leafy vegetation, to afford shade from the glare of the evening sun.
