THE PENINSULAR AND ORIENTAL COMPANY'S NEW STEAM-SHIP "DELTA." The vessel, the handsomest of her class that has yet been built on the Thames, has been constructed by the Thames Iron Shipbuilding Company, from lines furnished by Mr. Ash, of that firm, under the immediate superintendence of the Peninsular and Oriental Company's surveyor, Mr. Robinson : she is fitted up with all his and other recent improvements, each of which, as they are shown to contribute to the convenience and' comfort of the traveling public are adopted in the company's ships as they are built. She is 350ft. over all, with a beam of 35 ft. 3 in. Her engines, made. by Messrs. Penn, of Greenwich, were formerly in the Valetta, which ship was recently" fitted with engines of less power; and the speed she realised, and the rate of the Delta's going, prove incontestably that less power than has hitherto been considered necessary will, with the lines adopted in the naval architecture of the present day-at least such as are used by the present crack builders in London - obtain a higher rate of speed than used to be obtained with one third more, power in proportion to the tonnage. At the trial-trip of the Delta, in Stokes' Bay, the average of four runs at the measured mile gave a speed of 14.609 knots-the greatest ever attained at that place by any previous vessel. The Delta is more than double the tonnage of the Valetta, whose engines she now carries; and, though having on board 300 tons more coal, and displacing 1200 tons more than the above-mentioned vessel, the Delta obtained the same steaming results. She is fitted with Lamb and Summer's boilers; is 1960 tons burden, and of 400 horses nominal, with an indicated power of 1612 horses.
