Much might be written about the decoration of these yachts; but it may suffice to give illustrations of the dining- and drawing-rooms in the steam yacht _Beryl_, owned by the Right Hon. Baron Inverclyde. The saloons are in the Old-English style, and are treated with decorative freedom, but with strict simplicity. The walls in both cases are framed in solid figured white Austrian wainscot oak, highly finished and polished. The drawing-room has silk tapestry panels, relieved with chaste carving on the window canopies, dado rail and mantelpiece, and divided with bevelled and carved pilasters, with carved Corinthian capitals. In the dining-room, on the other hand, there is no tapestry, the whole being of oak, suitably carved. In the ports there are large plate-glass windows, fitted with Greenwood springs. In each room there is a large cupola skylight, which, with its rich stained glass, gives a fine decorative effect. The drawing-room cupola is fitted with a brass mushroom ventilator. The ceiling in each case is of yellow pine, moulded, ribbed, and beamed in the Tudor style, and painted flat white, picked out with gold. [Illustration: Plate XXV. THE DRAWING ROOM. THE DINING SALOON.] [Illustration: THE STEAM YACHT "BERYL," OWNED BY LORD INVERCLYDE.] The drawing-room has a slow-combustion grate having brass mounts, with richly-carved oak mantelpiece, marble jambs, tiled hearth, and fire-brasses and fender. The dining-room has a steam radiator enclosed in a cabinet with Numidian marble top and brass-grilled front. The _Beryl_ is a vessel of 160 ft. in length, with a displacement of 500 tons at slightly less than 12-ft. draught. She steams at 13.3 knots with the engines indicating 910 horse-power, steam being supplied from a large single-ended boiler with three furnaces. As typical of the engines adopted in the yachts built by the Scotts, we give an illustration on Plate XXVI., facing page 72, of the engines of the _Grianaig_. In the thirty years that have elapsed since the first _Greta_ was built, the ratio of horse-power to tonnage has increased from 1 to 1 to 2 to 1, the steam pressure from 74 lb. to 200 lb.; and the piston speed from about 300 ft. to 675 ft. per minute. The aim has been to ensure reliability by a steady- and easy-running engine. An effective appearance has always been aimed at, and the result has invariably been a highly-finish design. Yachts' engines are invariably balanced, whether so specified or not, as the gain in comfort to all on board, owing to the absence of vibration, is so marked as to more than compensate for the extra cost involved. Forced lubrication has also been applied, although the engines may be of the ordinary open type: the main bearings, crank-pins, cross-heads, eccentrics, valve gear, pump gear, etc., are all included in the system, which has given every satisfaction.
