The ORANGERY is entered by a massive doorway between two splendidly carved colossal lions, after Canova. It is 108 feet in length and 27 in width, and, beside its myriads of beauties as a conservatory, contains some exceedingly fine specimens of sculpture. From the centre of the Orangery egress is had to the grounds, and at its north end a corridor (in which are some pieces of ancient sculpture and mosaic) leads to the baths and to a staircase which gives access to the banqueting or ball-room, and the open pavilion. These are not, of course, shown to the public; but, nevertheless, a few words may well be added concerning them. The BALL-ROOM, or BANQUETING-ROOM, as it is sometimes called, is a magnificent apartment, 81 feet long by 30 in width, and very lofty. The ceiling is divided into compartments, each of which contains a beautiful painting set in richly-gilt framing; the whole of the intermediate parts being painted in fresco, with medallions of crest and coronet and monogram of the Duke. Prominent among the subjects on the ceiling are Sir James Thornhill’s “Perseus and Andromeda,” paintings by Louis Charon, and a view of Chatsworth, with allegorical figures in the front. Over this room is the open PAVILION, from which extensive and charming views of the surrounding country are obtained. [Illustration: _The Pavilion and Orangery, from the East._] The lower, or BASEMENT STORY, remains to be noticed. This, like the other stories we have described, runs round the four sides of the quadrangle of the main building; the basement of the north wing being devoted to the kitchens and domestic and business offices. The grand staircase occupies the inner south-east angle, the grand hall and various private apartments taking up the east side. On the north is the entrance, the sub-hall, the north corridor, and various private apartments. The west front is occupied by the Duke’s private suite of rooms, the Marquis of Hartington’s private rooms, the west entrance, the west staircase, and corridor. The south side comprises the south corridor, the Chapel at the south-west corner, the Oak Room, the south entrance, the Stag Parlour, and other apartments. It will only be our province on this story (having already described the sub-hall, north corridor, and grand hall), to speak of the corridors, the Chapel, and cursorily of one or two other of the apartments on this floor. Passing beneath the grand staircase in the great hall is the “GROTTO ROOM,” the ceiling of which, supported by four massive pillars and twelve pilasters, is divided into compartments; some of them being enriched by the _insignia_ of the Order of the Garter. Opposite the entrance is a boldly and powerfully sculptured fountain-piece, the central subject of which is Venus at the Bath; the accessories being dolphins, crabs, lobsters, fish, and other appropriate objects. To the east of this room is an ante-room giving access to the south-east sitting-room (a
