1559. Terrace and conservatory. We observed, when treating of ground, and of the ancient style, that the design of the terrace must be jointly influenced by the magnitude and style of the house, the views from its windows (that is, from the eye of a person seated in the middle of the principal rooms), and the views of the house from a distance. In almost every case, more or less of architectural form will enter into these compositions. The level or levels will be supported partly by grassy slopes, but chiefly by stone walls, harmonising with the lines and forms of the house. These, in the Gothic style, may be furnished with battlements, gateways, oriels, pinnacles, &c.; or, on a very great scale, watch-towers may form very picturesque, characteristic, and useful additions. The Grecian style may, in like manner, be finished by parapets, balustrades, and other Roman appendages.
