The White Star Company is also building two immense boats to be named the _Olympic_ and _Titanic_. They will be 840 feet in length and will be the largest ships afloat. However, it is said that freight and passenger-room is being more considered in the construction than speed and that they will aim to lower no records. Each will be able to accommodate 5,000 passengers besides a crew of 600. All the great liners of the present day may justly be styled ocean palaces, as far as luxuries and general appointments are concerned, but as the _Mauretania_ and _Lusitania_ are best known, a description of either of these will convey an idea to stay-at-homes of the regal magnificence and splendors of the floating hotels which modern science places at the disposal of the traveling public. Though sister ships and modeled on similar lines, the _Mauretania_ and _Lusitania_ differ somewhat in construction. Of the two the _Mauretania_ is the more typical ship as well as the more popular. This modern triumph of the naval architect and marine engineer was built by the firm of Swan, Hunter & Co. at Wellsend on the Tyne in 1907. The following are her dimensions: Length over all 790 feet. Length between perpendiculars 760 feet. Breadth 88 feet. Depth, moulded 60.5 feet. Gross tonnage 32,000. Draught 33.5 feet. Displacement 38,000 tons. She has accommodation space for 563 first cabin, 500 second cabin, and 1,300 third class passengers. She carries a crew of 390 engineers, 70 sailors, 350 stewards, a couple of score of stewardesses, 50 cooks, the officers and captain, besides a maritime band, a dozen or so telephone and wireless telegraph operators, editor and printers for the wireless bulletin published on board and two attendants for the elevator. The type of engine is what is known as the Parsons Turbine. There are 23 double ended and 2 single ended boilers. The engines develop 68,000 horse power; they are fed by 192 furnaces; the heating surface is 159,000 square feet; the grate surface is 4,060 square feet; the steam pressure is 195 lbs. to the square inch. The highest speed attained has been almost 26 knots or 30 miles an hour. At this rate the number of revolutions is 180 to the minute. The coal daily consumed by the fiery maw of the furnaces is enormous. On one trip between Liverpool and New York more than 7,000 tons is required which is a consumption of over 1,500 tons daily. There are nine decks, seven of which are above the water line. Corticine has been largely used for deck covering, instead of wood as it is much lighter. On the boat deck which extends over the greater part of the centre of the ship are located several of the beautiful _en suite_ cabins. Abaft these at the forward end are the grand Entrance Hall, the Library, the Music-Room and the Lounging-Room and Smoking-Room for the first cabin passengers.
