Decoration by means of rough woodwork, the park being left in place, or by means of uncut stones, artificial rockwork, or the like, or by such combination of these materials and devices as will cause the general appearance of what is thought to be rural in character. Where woodwork is used it is customary to provide a continuous sheathing as of boards, upon which are nailed the smalllogs and brancheswith their bark, moss, etc., carefully preserved; but these strips of wood are often arranged in ornamental patterns, causing anything but a rural appearance.
