The carvings in this noble apartment are of matchless character, and hang in a profusion that is almost bewildering. In the panels of the wainscoted walls are festoons of flowers, &c.; over one doorway is a group of leaves and corn, and over the other two are splendid groups of crabs, lobsters, fish, and shells, all “as true to nature as nature itself.” Over the fire-place, across the top, and hanging down the sides of an octagonal tablet, is the richest of all the rich carvings of this suite of rooms. It consists of dead game—heron, pheasants, &c., at the top; over and around these a net is loosely thrown, which, hanging down the sides, forms a groundwork of festoons, on which hang pheasants, woodcocks, grouse, partridges, snipes, and other birds, so true to life that it is only by careful examination that the spectator can discover that they, with the net and all the mouldings, are carved out of solid wood. In this room are several busts in marble by Chantrey, Nollekens, and others. Among these are the Emperor Nicholas of Russia, and his Empress; Fox; Canning; Francis, Duke of Bedford; Lord G. H. Cavendish, &c. There are also cabinets of rare old china. On the central table will be noticed, among rare and valuable articles, the rosary of King Henry VIII.; a fine set of carved ivory chessmen; ivory-carvings, rare glass and china; and silver filigree and other ornaments. And there is also the malachite clock presented to the late Duke by the Emperor Nicholas of Russia, and an exquisitely sculptured marble model of the Victoria Regia. From this room a doorway opens on to the GRAND STAIRCASE—the casings of the doorways, of exquisitely-carved marble, being worthy of especial note—in the south-east angle. Opposite this doorway another door opens into a suite of apartments, of course not shown to visitors, but to which some brief allusion may here be made. Here are the rooms usually known as MARY QUEEN OF SCOTS’ ROOMS, but which really have no possible connection with that ill-fated lady. They are so called because they occupy the same position in the present building as those used by her did in the old one; they overlook the inner court, or quadrangle, on its east side. The other suites of bed-rooms adjoining are known as the “Leicester” and “Wellington” rooms, and they are fitted, as may well be supposed, in a style of princely magnificence. In one of these rooms is the bed and bed-room suite used by Her Majesty Queen Victoria when a guest at Chatsworth. This suite is of satin-wood, hung in green and white satin.
